Of course, all of us have our own style and approach to how we try and communicate in class. So this guide is not intended as being in any way prescriptive. However, it does contain materials that I use when teaching my own MBA and undergraduate classes in this subject. If you have any comments on how we can improve the book or on this teaching guide, please do not hesitate to contact me at nigel.slack@wbs.ac.uk. Content Six types of material are included in this guide. They are • Course plans • Topic teaching guides • Extra cases and teaching notes • Student study guides • PowerPoint slides Course plans The section on course plans is intended as a guide to how the topic can be divided amongst a number of sessions. Clearly, how this is done will depend on many factors, the most important of which is the number of sessions available. Suggested topics are given for courses of one, two, three, five, eight, ten and twelve sessions. 1 This tutor’s guide is intended to accompany ‘Slack N and Lewis M A (2011) Operations Strategy, 3rd Edition, Financial Times Prentice Hall 5 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Topic teaching guides A separate teaching guide is given for each topic (i.e. for each chapter of the text). This indicates the cases that could be used to illustrate and demonstrate some of the issues in the topic. These cases are drawn both from the cases included in the final section of the book and the extra cases provided under ‘Extra cases and teaching notes’. Each teaching guide also contains a number of discussion points, exercises and teaching tips which you may find useful. Extra cases and teaching notes In the first edition of Operations Strategy we included a ‘Case Exercise’ at the end of each of the 15 chapters. Although these cases are no longer in the book itself, they are available in this section of the teaching guide together with teaching notes that will help in debriefing the cases. Student study guides This section of the guide contains study guides that relate to each chapter in the text. These study guides are relatively substantial pieces of work. They can be used either as a ‘background primer’ for lecturers before they take a class in the topic. Alternatively, they can be copied and handed out to students to support students’ individual learning before or after the relevant class. It is hoped that these study guides together with the text will provide a complete learning package that will support students in their studies. PowerPoint slides A full set of PowerPoint slides are included for each chapter. These sets of PowerPoint slides contain not only some of the figures that are included in the text but other slides that you may find useful in teaching. They are presented as a menu of slides rather than a prescription of how you should teach the class. Please feel free to use only the ones that you find useful in communicating the subject. 6 © Nigel Slack and Michael Lewis 2012 Operations strategy Course plans1 Putting a course curriculum together Putting a course curriculum together depends on a number of factors, amongst which are • The time available (number and length of sessions) • The expressed needs of the students • The experience of the students • The other courses that students are studying • The preferences and competences of teaching staff Given the almost infinite number of possible combinations that the list above could generate, it would be a mistake to try and provide any prescriptive list of topics that should be included in a course. However, the following table may provide a broad guide to how the chapters in Slack and Lewis could be divided between sessions.

What is strategy? What is operations strategy? 51 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual How should operations strategy reflect overall strategy? How can operations strategy learn from operational experience? How do the requirements of the market influence operations strategy? How can the intrinsic capabilities of an operation’s resources influence operations strategy? What is the ‘content’ of operations strategy? What is the ‘process’ of operations strategy? The objective of teaching this topic is primarily to convince students that operations management isn’t always ‘operational’. Although Operations Management does deal with the more operational aspects of the operations functions’ activities, operations managers have a very significant strategic role to play. It is also important to demonstrate that there is a whole range of performance criteria that can be used to judge an operation, and which operations managers influence. ('…..although cost is important and operations managers have a major impact on cost, it is not the only thing that they influence. They influence the quality that delights or disappoints their customers, they influence the speed at which the operation responds to customers’ requests, they influence the way in which the business keeps its delivery promises and they impact on the way an operation can change with changing market requirements or customer preference. All these things have a major impact on the willingness of customers to part with their money. Operations influence revenue as well as costs.') It is also vital to stress to students the importance of how the operations function sees its role and contribution within an organisation. ('… you can go into some organisations and their operations function is regarded with derision by the rest of the organisation; how come, they say, that we still can’t get it right. This is not the first time we have ever made this product or delivered this service. Surely we should have learned to get it right by this time! The operations people themselves know that they are failures, the organisation does nothing but scream at them, telling them so….. Other companies have operations functionaries who see themselves as being the ultimate custodian of competitiveness for the company. They are the A team, the professionals, the ones who provide the company with all they need to be the best in the market…') Other objectives are • To explain that there really is something very important embedded within operations and processes. The skills of people within the operation and the processes they operate are the repository of (often, years of) accumulated experience and learning. • To give examples of how markets and operations must be connected in some way. Whether this is because operations are being developed to support markets, or markets are being sought that allow operations capabilities to be leveraged, it doesn’t matter. The important issue is that there should always be a connection between the two. Possible lesson elements Teaching hint – Teaching the nature and importance of the various performance objectives can be done in two ways. 52 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual One can look at each performance objective in turn, using examples of where the particular performance objective has a special significance. For example, • Quality – Use companies (like Bentley or Toyota) that have a reputation for quality products or services. High quality hotels and restaurants can be used, as can luxury services such as high price hairdressers, etc. This can prompt a useful discussion regarding what we mean by quality (although you may wish to reserve this for the lesson on quality). Alternatively, use an example where high conformance is necessary for safety reasons such as blood testing in hospitals. • Speed – Any accident, emergency or rescue service is useful to discuss here. The consequences of lack of speed are immediately obvious to most students. Also, use transportation examples where different speeds are reflected in the cost of the service. First and second class postage is an obvious example as are some of the over-night courier services. Likewise, the fast check-in service offered to business class passengers at airports and the exceptionally fast service of Concorde (depending on whether it is flying when you are reading this!) that offers a fast service at a very high price. • Dependability – Some of the best examples to use here are those where there is a fixed ‘delivery’ time for the product or service. Theatrical performances are an obvious example (or the preparation of lectures). Other examples include space exploration projects that rely on launch dates during a narrow astronomical ‘window’. • Flexibility – We have found the best examples here to be those where the operation does not know who or what will ‘walk through the door’ next. The obvious example would be a bespoke tailor who has to be sufficiently flexible to cope with different shapes and sizes of customers and also (just as importantly) different aesthetic tastes and temperaments. A more serious example would be the oil exploration engineers who need to be prepared to cope with whatever geological and environmental conditions they find drilling for oil in the most inhospitable parts of the world. Accident and emergency departments in hospitals can also provide some good discussions. Unless they have a broad range of knowledge that allows them to be flexible they cannot cope with the broad range of conditions presented by their patients. • Cost – Use the example of low-cost retailers who have achieved some success in parts of Europe by restricting the variety of goods they sell and services they offer. Teaching hint – Try establishing the market-operations link by referring to organisations familiar to the students. Even the ubiquitous McDonalds can be used (in fact there is a very good case on McDonald’s operations in the Harvard Business School series; contact The Case Clearing House for details). The important issue however is to raise the focus of discussion from managing a single part of the organisation (such a single McDonald’s store) to managing the operations for the whole organisation (for example, what are the key operations strategy decisions for McDonald’s in the whole of Europe?). The discussion can then focus on the difference between the two levels of analysis. Discussions can especially look at how the operational day-to-day issues (such as, the way staff are scheduled to work at different times in McDonald’s stores) can affect the more strategic issues for the organisation as a whole (such as, what level of service and costs are McDonald’s franchise holders expected to work to?). 53 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Exercise – One method of establishing the connection between markets and operations is to ask the class members to find a business-to-consumer website, formally list the ‘marketing’ promises that the website makes and then think about the operations implications of these promises. For example, what will the company have to do in terms of its inventory management, warehouse locations, relationships with suppliers, transportation, capacity management and so on in order to fulfil its promises? 54 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 2 Topic – Operations performance Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 2 of Slack and Lewis Boyer, K.K. and Lewis, M.W.

Do the role and key performance objectives of operations stay constant or vary over time? Are trade-offs between operations performance objectives inevitable or can they be overcome? What are the advantages and disadvantages of focused operations? This chapter covers four important issues relating to operations performance. The chapter is placed at the beginning of the book because it provides some of the basic ideas that reoccur throughout the treatment of the various topics in both the content and process of operations strategy. However, it could equally well have been placed towards the end of the book if one wanted to relate back to the various examples used throughout the book in order to demonstrate the nature of operations performance. So, from a teaching perspective, one might want to think about delaying some of these issues towards the end of the course. The four issues related to operations performance that are covered in the chapter are as follows: • There are five ‘generic’ performance objectives. However, note that one may introduce a broader perspective on operations performance at this point, including aspects of corporate social responsibility (CSR) and so on. • The relative importance of these performance objectives changes over time. The text uses the VW example to illustrate this over a number of decades. But several of the cases listed above could also be used to demonstrate this point. • There are trade-offs between the various performance objectives. The text uses the ‘efficient frontier’ concept to illustrate this. But in addition, it is worthwhile exploring the debate over whether trade-offs are real or imagined, and in particular the idea that trade-offs are very real in the short term but can be overcome in the long term. • Focussing an operation on a very small number of performance objectives can lead to superior performance in those objectives. This is the classic ‘focussed factory’ idea that Skinner raised several decades ago. Of course, it applies equally to non-manufacturing operations. Possible lesson elements Teaching hint – An important point to get over here is that performance objectives differ for different operations with different strategies. It may seem obvious but it is fundamental and not all students grasp this initially. An obvious way of demonstrating this is to take two well-known companies in different parts of the same sector competing in different ways. For example, ask the students to contrast a well-known low-cost airline such as Ryanair with Virgin Atlantic’s Upper Class service. 56 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Exercise – Relating to the above point, one could ask students to explore the websites of two organisations such as Ryanair and Virgin and from that deduce differences between the relative importance of each performance objective. Discussion point – ‘Surely the level of service offered by Ryanair is now so low that customers will not be prepared to put up with it even at rock bottom prices?’ Exercise – The text quotes various statements from the website of some well-known companies that emphasise one or more performance objectives. One could ask students to explore some other company websites and identify their stated performance priorities. Teaching hint – Polar diagrams are particularly useful when summarising any company’s performance objectives. What ever company is being discussed, it is useful to have a summary of its strategic stance in the form of a polar diagram. Exercise – One can refine the idea of the relative importance of performance objectives by asking students to distinguish between qualifiers, order winners and delights. Any of the ideas already mentioned can be used to do this. Exercise – The idea of delights is especially useful for teaching experienced students. One can ask them to identify one product or service and ask them to distinguish between qualifiers, order winners and delights now and in the future. See the study notes associated with Chapter 2 for more details on this. Teaching hint – The illustration of how performance objectives change over time used in the chapter is that of VW. One can ask students to take another company with which they are familiar (this works particularly well for experienced students) and trace its history as far as back as their knowledge extends. They could then identify the various phases that the business may have gone through and the associated changes in the relative importance of performance objectives. Exercise – One of the best illustrations of trade-off and focus comes from the (now rather old) Shouldice Hospital case (see Case Clearing House). If you regard this case as too old, you could ask students to look up Shouldice Hospital’s website and ask what trade-offs seem to have been made. Discussion point – ‘Trade-offs are all in the mind. Look at how we used to think about the trade-off between cost and quality when buying automobiles. It was assumed that you had to spend money in order to get a car without defects. The Japanese showed us that it is perfectly possible to get great quality and low price at the same time. In fact, achieving an error-free production process actually reduced the cost of manufacturing the vehicle and therefore reduced the price that could be charged. It is the same with all other types of trade-off isn’t it?’ 57 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 3 Topic – Substitutes for strategy Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 3 of Slack and Lewis Spear, S. and Bowen, H.K.

How do Lean Operations fit into operations strategy? How does Business Process Reengineering fit into operations strategy? How does Enterprise Resource Planning fit into operations strategy? How does Six Sigma fit into operations strategy? What place do these new approaches have in operations strategy? 58 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual This is a slightly unusual chapter in the context of operations strategy. We have included it in the third edition of the text for two reasons. First, users of the text asked us to include brief descriptions of some of the more popular and important approaches that are common currency within operations strategy because students were increasingly asking about these approaches. Second, as we say in the chapter, many organisations believe that by adopting one of these approaches they are adopting an operations strategy. The main point of this chapter is to demonstrate that none of these approaches is a complete operations strategy as such. Nevertheless, the decision to adopt one of these approaches is a strategic decision. Prior to adopting the approach, it is important to understand exactly what it means, what is implied by adopting the approach and how it may have to be adapted over time. In some ways, although the bulk of the chapter comprises brief descriptions of these new approaches, the important discussion comes at the end of the chapter. It is of course important to ensure that students understand the elements within each of these new approaches (which is one of the points we make in the chapter), but it is even more important that they are able to compare and contrast the approaches. The way we do this is to discriminate in terms of two dimensions, radical change versus incremental change and a concentration of process versus a concentration of exactly what changes should take place. This is only one way of discriminating between these new approaches. We find it useful but you may wish to adopt a different approach. Possible lesson elements Teaching hint – Start the session by asking students to identify some of new approaches that they have either come across in their own organisations or (if they are inexperienced students) have heard about. Write these approaches down (they may mention more than the ones we look at the in chapter) and explain the chronology of the approaches, where they originally came from and so on. Discussion point – 'A lot of organisations tried Total Quality Management. If it has been that useful they would still be doing it and yet TQM is now unfashionable. It can’t be any good.' Exercise – Lean operations principles lend themselves to games of various sorts. Simple production games where students make cards or use Lego can be used to demonstrate the effect of between stage inventories and/or pull control. Different games can be devised, especially to demonstrate lean ideas. Here are two ideas. Take a cheap and easily available product that students can easily disassemble and assemble as a mock assembly line. We use electrical plugs. These have to be of the type with enough bits inside them to make the total disassembly/assembly task into four or five stages. Equip the four or five ‘volunteer’ students with appropriate technology (screwdrivers) and set the process running. Initially, allow as much inventory to build up as they wish (this is why a small product is useful). Take keys measures over a three or four minute period such as the number produced, the total throughput time, the amount space of used, the total inventory in the system and so on. Then run the game again, this time with ‘kanban squares’ of (say) one or two units only, between the stages. Demonstrate how this increases throughput time and reduces inventory. As an alternative to a simple product such as the domestic electrical plug, devise a product made with Lego bricks. This involves some initial outlay in order to purchase enough Lego to allow the game to run for some minutes. However, the advantage is that it is easier to balance the 59 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual amount of work at each stage in the line and also one can allow ‘design changes’ and improvements in the system more easily. Teaching hint –There is still an old video in circulation showing the above being done at Hewlett-Packard. The video dates from about 1984 and unfortunately the clothes worn by the people in the video make this obvious. Nevertheless, the video does demonstrate the principles well. And it is now so old that one can make the point to students from service operations that manufacturing operations were starting to understand lean synchronisation (or JIT as they would have called it) 20 years ago. Ask them why it has taken so long to be recognised as being valuable in service businesses? Exercise – With smaller groups such as smaller MBA classes, or even executive classes, let everybody participate in these games in teams of five or six people. After the first one or two runs, set them the challenge of improving the process. While they are doing this walk amongst them with a video camera try and capture shots of them attempting to improve the process. It is not usually difficult to find examples of single individuals dominating discussion, groups splitting into two to do their own thing, poor communication, arguments and so on. The session can then be broadened out and illustrated using selected highlights from this video. This is especially useful for covering the continuous improvement and human issues in lean operations. Teaching hint – Lead a discussion on how lean principles could be used in a retail operation. Lead this discussion back into a discussion of supply chain and how the whole supply chain, from raw materials suppliers through to the retail operation, can be governed using lean synchronisation principles. Exercise – For Six Sigma it is particularly important that students come to understand the nature of variation in process performance and how it can affect quality. We have found the best way to do this is to devise games to demonstrate the choices that need to be made when dealing with variability. Fortunately, it is not difficult to devise games of this sort. Here are two options. • Game 1 – Find some easily available product that contains pieces, supposedly of the same size. We use the small wooden blocks that are used in some children’s building sets and games. Instruct groups of students to measure successive blocks using a micro measuring device (available at specialist and hardware stores). Get them to plot on an SPC chart the variation in the size of the blocks and from that calculate the central and control limits for mean and range. • Game 2 – Do something similar but select an Internet search site such as one that searches for cheap flights or hotel accommodation. Get the students to time the variance in response time and calculate limits as before. The advantage of this approach is that one can ask students to sample from the same site at different times to check whether the process is getting ‘out of control’. Teaching hint – Off-air video clips are particularly useful for teaching quality. One can use any short piece of video that simply shows an operation in practice. Retail organisations, hospitals, trucking companies and so on are all shown frequently on air. Alternatively, select a ‘business’ programme that may have more in-depth pieces. Show the video to students and ask them to define what quality would mean for such an operation. Teaching hint – If one is treating ERP, it can be a complex issue for students to understand. Try basing examples around cooking meals in a domestic situation. Simple recipes and simple numbers are recommended. Inevitably, one will have to simplify the recipes greatly, but this approach does have the advantage of relating to an activity that (some) students might understand. 60 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 4 Topic – Capacity strategy Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 4 of Slack and Lewis Kopper A.

How much capacity should an operation have? How many separate sites should an operation have? 61 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What issues are important when changing capacity levels? Where should capacity be located? Capacity is regarded by some people as a particularly ‘dry’ subject. The reality is very different. Not only is the idea of capacity at the very heart of what operations management is about, the failure to get capacity decisions right in the long term (or in the short term for that matter) can be dramatic and sometimes disastrous. Not only that, but there are always examples of capacity strategy in the press. News stories that look at location decisions, reducing capacity by reducing the number of jobs in a firm, being surprised by the volume of demand, getting forecasts hopelessly wrong, and so on, can all be exploited to illustrate aspects of capacity strategy. In particular, a number of key points are addressed by the chapter. • How we manage capacity in the longer term is influenced by both market and operations resource factors. • The idea of the breakeven point is hugely important. Profitability and volume are not always related in a straightforward manner. • The idea of economies of scale and diseconomies of scale apply to all types of operation. In particular, diseconomies of scale are a function of customer perception as well as the straightforward cost implications of scale. • Various decisions that make up a capacity strategy are interrelated. In particular, the idea of how many sites, how big each site should be, whether it should be specialist or generalist, and its location, are all connected. • The dynamics of capacity change are as important as a static analysis. As volume changes capacity must also change. Making changes that are too early, too late or of the wrong magnitude can all have serious consequences. • Location is becoming a particularly important decision. The economies of location in many industries are changing fundamentally. Easier communication and globalised industries mean that the number of location options available is now often very great. Possible lesson elements Teaching hint – One way to promote a discussion on location issues is to choose a decision currently in the press. Often this can be a government-originated project such as a sports stadium or museum. The class can then be led through the criteria which may be used to decide on the location. Exercise – A related but different exercise can be constructed by asking the class to consider how they would make their local area more attractive to incoming business. ‘If you were the local government officer in charge of attracting business to this area, what could you do to make the area more attractive?’ 62 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Teaching hint – Try contrasting the different approaches to location taken by different types of business. For example, compare the location decision facing a company wishing to build a new factory in a region, with a fast-food restaurant looking for a location in a town where it has no existing outlets. The idea here is to contrast two very different types of location decision. • The new factory location would follow the ideas as set out in the chapter. These tend to assume that location is being chosen primarily on the grounds of minimising the costs associated with the site. The amount of products sold by the company is unlikely to be very much affected by its location, but its costs could be very much affected by location factors. Furthermore, there are likely to be a very large number of sites that the company could choose from. • The fast-food restaurant, on the other hand, is a different sort of location decision. Both revenue and costs will be affected by location. Locating the restaurant away from other restaurants and/or away from passing trade is likely to mean a reduction in revenue. Some locations are better than others at attracting customers. Also, the costs of the location (such as rent and rates etc.) are affected by location. Finally, there are rarely a large number of options to choose the location from. Usually location is more opportunistic. The fast-food restaurant might wait until a site becomes available and then take the decision as to whether to have that site or to wait in case a better one becomes available. Teaching hint – It is important to get over the importance of forecasting in capacity strategy. There are plenty of examples of bad forecasts and there are plenty of examples of saying associated with forecasting. (My personal favourite comes from Paul Gascoigne the footballer, who is reputed to have said, ‘I never make predictions and I never will’). Exercise – The example on IKEA can be made into an interesting little exercise. Ask students to devise two lists. The first list identifies all the factors that contribute to economies of scale at IKEA. The second list identifies the factors that may contribute to potential diseconomies of scale. Ask the students to reflect on how many of the factors that influence diseconomies of scale are either perceptual (it is a maze in there, you can’t get out for hours) or born by bodies other than the company (traffic congestion etc.). Exercise – The idea of breakeven points will be familiar to some students so it is important to choose an exercise that both gets over the main ideas and yet provides some interest for students who are familiar with the topic. The Freeman Biotest case does both these things. Exercise – The Delta Synthetic Fibres case that included in the book works particular well if you can ask the students to build a simple spreadsheet model to examine the effects of different timing strategies on the profitability and cash flow of the company. Discussion point – ‘Just look at the example of Wholefood Markets that is described in Chapter 4 of Slack and Lewis, would you really want to buy organic food from a huge factory-like place like that?’ Teaching hint – The idea of clustering in location is a useful one to explore in class. The obvious cluster to discuss is that of Silicon Valley. However, one can normally find various clusters in whatever region you are teaching. The one I use in the UK is the manufacture of racing cars (both for Formula 1 and for Indie Car Racing) most of which are made in the UK. Get the class to discuss exactly why clusters occur. 63 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 5 Topic – Purchasing and supply strategy Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 5 of Slack and Lewis Harvard Business School.

In what way do companies try to change the nature of the supply network of which they are a part? One of the more important points made in Chapter 1 of the text is the idea that operations management can be analysed at three levels, the level of the supply network, the level of operation itself and the level of individual processes. This chapter is concerned with the decisions relating to supply networks. It is worthwhile thinking about how one positions the whole idea of supply network strategy. The way we have positioned the topic in the text is as a part of the overall set of decisions that go together to make up an operation’s strategy. An alternative, and in some way equally valid, perspective is to see supply network strategy, or ‘supply strategy’ as the overarching idea that dominates what we have called ‘operations’ strategy. If you prefer this view then obviously the material contained in this chapter must come earlier. It may even be merged with the type of topics contained in our Chapter 1. Given one is using the topic in the way it intended in this book, there are a number of key points to get over in any session devoted to supply network strategy. • All organisations have a supply network. One does not have to have any physical flow of physical products in order to have suppliers, customers, suppliers’ suppliers, customers’ customers and so on. • A supply network perspective is by definition a strategic perspective. • Globalisation has changed the nature of how we think about supply networks. • The nature of relationships between different operations in a supply network goes a long way to explain the capabilities of the supply network. • Outsourcing or vertical integration is a particularly important topic given the globalised circumstances of many operations in recent years. • Conventional marked-based supply relationships are more common than is realised and may be perfectly appropriate under certain circumstances. • Partnership relationships are a great idea in theory and can work in practice but pose some very significant difficulties. • Supply networks are dynamic, disturbances in one part of the supply network will have effects on other parts of the supply network. • Improving the performance of supply networks is usually a combination of operational changes and (perhaps more significantly) changes to how the network is configured. 65 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Possible lesson elements Teaching hint – We have found that one of the most important points to come out of this chapter is an understanding of the whole concept of a supply network. One method of achieving this is to lead a discussion on the supply network for a familiar operation such as a restaurant. Suppliers can be traced back to food items, consumables such as napkins etc. Each of these can then be traced back to the suppliers’ suppliers, back to the farm or paper factory etc. Similarly, moving downstream in the supply network, one can work to the consumer directly, or assuming that the restaurant supplies events such as dances and weddings, to the wedding organiser and then to the ultimate consumer. Teaching hint – Try tracing the development of a supply network over time. An ideal one is that for the recorded music industry. Back in the 1950s record labels owned their own recording studios, orchestras, engineers, arrangers, artists and so on. They also often made their own albums and distributed them to their own retail outlets. Contrast this with what a supply network might look like with internet-based distribution of MP3 files. Exercise –Dell is an interesting example. Ask the students to revisit this and draw Dell’s supply network and contrast it with the supply networks of other computer companies. Ask them to list the advantages and disadvantages of Dell’s model. Exercise – Ask students to draw the supply chain for a conventional music store selling CDs and also for iTunes. Ask them to identify other industries that might adopt a similar model to iTunes. (The movie and DVD industries are obvious examples). Exercise – Following on from the former exercise, ask the students to identify as many industries as then can that will be particularly affected by further developments in internet-based channels of distribution. Ask them to draw supply chains that illustrate exactly how they will be affected. Exercise – At the time of writing (2010) possible the most useful example of supply chain innovation is that of Zara. A synopsis of the Zara phenomenon is included in the Inditex case in the final part of the book. There is also a far fuller case available through the Case Clearing House (co-authored by one of the authors of this book, Mike Lewis) and a video produced by Harvard Business School. Either or both can be used very successfully in teaching sessions. Exercise – The idea of ‘trust’ is fundamental to developing supply relationships. The Prisoner’s Dilemma illustration of game theory can be used to distinguish between how businesses can cooperate to maximise the benefits to the group or to operate individually to attempt to maximise their individual benefits. The well-known ‘red-blue’ game can be used to illustrate this (just search on the internet for ‘red-blue game’). Similarly, if students have seen the film ‘A Beautiful Mind’ one can direct them to the scene where Russell Crowe describes the nature of game theory in a bar. Discussion point – ‘All this idea about partnership is nonsense. The nature of business is competition and the nature of competition is trying to maximise ones own return from all business deals. Partnership is just asking businesses to behave in an unnatural manner. It is always going to be doomed to failure’. Exercise – Perhaps the best-known of all management games in this area is the famous ‘Beer Game’. Again, if you have never played this with a class simply use a search engine on the internet and you will find the rules. It is a powerful illustration of supply chain dynamics but it does need practice. If you have never taught it before, do practice with colleagues first! 66 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 6 Topic – Process technology strategy Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 6 of Slack and Lewis McKeen J.D.

What are suitable dimensions for characterising process technology? How do market volume and variety influence process technology? How can process technology be evaluated strategically? There are so many different processing technologies used in operations that it is probably not worth trying to cover all types. However, it is important to make it clear to students that the changing capabilities of process technologies can open up new opportunities for operations. We find it useful therefore to concentrate (a) on the general issues associated with process technology strategy and (b) on newer forms of technology. What is important is to try and get students to think through the implications of adopting process technologies. In doing this it is useful to try and identify new technologies that have not yet been fully developed. For example, security systems are starting to use scanners which take a photograph of a person’s iris in order to verify their authorisation to enter a building or to take money out of a machine etc. A discussion around the operations implications of such new security technologies can be more interesting and rewarding than one which concentrates on a manufacturing (say) technology with which the students may not be familiar. The other way to approach process technology is to do so through the task of evaluation. Any exercise which involves comparing alternative technologies can be used not only to think about the process of evaluation but also to discuss some of the underlying characteristics of the technology in question. Some key points to cover in a session include the following: • To overcome the reluctance of some students to consider process technology as anything other than ‘what engineers do’. • To establish the idea that all operations have some type of process technology. • To illustrate various types of material, information and customer processing technology. • To examine the strategic relevance of process technology choice and development. • To establish the three generic dimensions of process technology, automation (or analytical content), scale (or scalability) and coupling (or connectivity). • To establish the main criteria for evaluating alternative process technologies. Possible lesson elements Exercise – Write up a list of different operations (restaurant, cinema, road side rescue service, bank, etc.) and get the students in groups to answer the following questions. What process technologies are used in these operations? 68 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What advantages does the process technology bring to the operation itself and its customers? How might recent changes and innovations in process technology affect the way these operations use their process technology? What criteria do you think these operations would use to decide whether to invest in new process technology? Teaching tip – Choose an emerging or potential technology and prompt a discussion on its implications for managing operations (e.g. what would be the impact on the operations managers in several business of the widespread adoption of fuel cells in cars?). Teaching tip – Hold a discussion on the impact of MP3 compression on record retailing operations. Discuss whether this is only a threat to record retailers or whether they could harness the technology in some way. Discussion point – In any type of information technology (IT) the issue of scale just does not matter anymore. The only thing that matters is scalability. That is, ‘how easy it is to extend the operating capacity of the technology as quickly as possible’. Exercise – Use the example ‘Will computers eventually do everything?’ as a starting point and ask students, in groups, to identify how computer-based technologies will extend their analytical ability over the next 5 years. Then ask them to identify some of the implications for managing operations of these possible developments. Exercise – The product–process matrix is a particularly important idea to get over to students. If students have some significant degree of work experience it is sometimes possible to group them so that each group represents a particular type of industrial sector. One can then ask them to identify different types of process technology at different parts of the diagonal on the product–process matrix. Exercise – The evaluation framework that uses the three categories of feasibility, acceptability and vulnerability, can be easily structured into an exercise. The simplest way to do this is to ask students to identify a technology purchase that they have recently made in their domestic lives. A more complex exercise would involve them identifying or exploring technology choices that have been made in their own work setting. 69 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 7 Topic – Improvement strategy Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 7 of Slack and Lewis Goldratt, E.M., Cox, J. and Whitford, J.C.D.

How do the needs of the market direct the ongoing development of operations processes? How can the ongoing management and control of operations be harnessed to develop their capabilities? What can operations do to deploy their capabilities into the market? The idea of improvement as an important topic within operations management is now fairly well-established. This chapter attempts to identify the fact that improvement is also a particularly important topic within operations strategy. In particular, all organisations need some strategy that guides their improvement efforts. Given this more strategic nature of the topic, there are fewer individual improvement techniques as such in this chapter than one would find in an operations management text. The ideas covered are more generic and conceptual in nature. The overall framework for the chapter is derived from the four perspectives of operations strategy as originally identified in Chapter 1 of the text. Using these four perspectives, one can identify four aspects of improvement, three of which are unambiguously the concern of the operations function. These are as follows. • Understanding the nature of the existing market positioning adopted by the organisation and translating this into a set of operations resources that will meet the requirements of the market. This is called ‘direct’ in the text. • Developing the internal competencies of the operation’s resources so that they can contribute to the organisation’s strategy as a whole. These competencies should give something to the organisation that is unique and difficult to copy, which allows it to adopt a market position superior to that it is occupying currently. This is called ‘develop’ in the text. • Leveraging the operation’s capabilities into the marketplace so as to achieve sustained competitive advantage. This stage is called ‘deploy’ in the text. Possible lesson elements Exercise – The idea of performance measurement is relatively easy to devise exercise around. For example, get students to identify operations with which they are familiar (fast food restaurants, shops, public transport systems, etc.) and task them with devising suitable performance measurement systems. This should involve them deciding on the most important performance objectives for the type of operation, devising performance measures that reflect the performance objectives, debating the most appropriate form of performance standards and then discussing the practical implications of how to make such a performance system work. For example, how often measurements should be taken, who should take the measurements and so on. Teaching hint – If you are feeling bold, ask the students to list ways in which the performance of a university lecturer could be assessed! 71 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Teaching hint – Get students to devise benchmarking strategies for different types of operations. For example, ‘how could a retail bank benchmark itself against its competitors’ levels of branch service?’ Exercise – The importance-performance matrix teaches particularly well and of all the techniques and approaches described in the book this one is probably the most successful across the broad spectrum of teaching that we do. The technique is only commonsense but the way in which it is structured seems to enable students to understand the nature of prioritisation in operations improvement. There are a number of ways it can be approached. The obvious approach is to use the Kaston Pyral case in the extra case section of this Instructors Manual. This contains a representative mixture of subjective (and pseudo objective) data. More importantly, it can be used to both demonstrate the technique and prompt debate on what the owner could do to improve performance. Exercise – An alternative way of demonstrating the importance of performance matrix where students have some industrial experience is to devise an exercise around that experience. For example, see below. • Step 1 – Choose an operation with which at least one of your group is familiar. The operation should have a relatively clear customer group and also direct competitors. The person or people who know about the chosen operation should act as the sources of information, the rest of the group act as consultants. • Step 2 – Identify the set of competitive factors that have some relevance to this operation. One can use the list of generic performance objectives as a starting point in doing this. So, use quality, speed, dependability, flexibility and cost and expand on each of them if necessary. • Step 3 – Rate each of these on the 9-point importance scale. • Step 4 – Now judge each of these against the 9-performance scale • Step 5 – Position each aspect of performance on the importance-performance matrix in a similar way to the example shown in the text. • Step 6 – Discuss how you might improve the objectives with the highest priority. Discussion point – 'OK, continuous improvement may have its place, but you will never get truly radical change by using continuous improvement. No set of people working at the operational level of the organisation will ever have the vision, knowledge or motivation to make the really dramatic breakthroughs that all companies need.' Exercise – The balanced scorecard as described by Kaplan and Norton is discussed in the chapter. These authors have extended this idea in a particularly useful fashion for dealing with strategic improvement. They call this ‘strategy mapping’ and it is explained in their book, Kaplan, R.S. and Norton, D.P. (2004) Strategy Maps: Converting intangible assets into tangible outcomes, Harvard Business School Publishing Corporation, Boston, MA. It contains many different exercises that can be constructively used, especially with experienced students. Exercise – The idea of developing operations capabilities is an important one to stress. However, it does sometimes confuse students because most development activities are operational in nature yet the consequences of effective operations development are strategic in 72 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual their outcomes. The ‘Turnround at the Preston Plant’ case is particularly useful in illustrating this point. The case is included in the final section of this book. Note that it does require the students to have some idea of statistical process control, not in any great detail, but at least in terms of its objectives. Exercise – The Bohn scale of knowledge described in the chapter can also be made into an exercise. Ask students to identify a process with which they are familiar and then debate what their state of process knowledge is. Exercise – Hayes and Wheelwrights 4-stage model can also be turned into an exercise. See the Study Notes for an example of how to do this. 73 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 8 Topic – Product and service development and organisation Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 8 of Slack and Lewis Cross, R. and Baird, L.

What process do companies use to develop products and services? How should the effectiveness of the product and service development process be judged in terms of fulfilling market requirements? What operations resource-based decisions define a company’s product and service development strategy? Product and service development is not a difficult topic to teach. Largely, this is because all students have bought products and all students have experienced services. Given that customer reaction is an important objective of the design activity, it is easy to use the student group as a sample of consumers and ask them to evaluate alternative designs, and then speculate on some of the organisational decisions that the provider must have taken in order to produce these designs. The main objective of the session is to show how this topic can be analysed in the same way as an organisation’s whole operations strategy. Many of the ideas already explained in the text (for example, the operations strategy matrix) can be used to describe the issues involved in an organisation’s product/service developmental activities. A further objective is to illustrate that there are degrees of development from relatively minor to very major. The degree of development is a significant influence on how product/service design is organised. Key teaching objectives include the following. • To convince students that product and service design is an important issue in terms of its impact on strategic success. • To establish the idea that product and service development can be analysed as an operations strategy. • To examine the resource implications of product/service development in terms of capacity, supply network, technology and organisation. Possible lesson elements Teaching hint – The UK’s Design Council site (www.design-council.org.uk) is a great source for examples and illustrations of product and service design and development. Teaching hint – The issue of sustainability in design is always worth discussing. It may also serve to catch the interest of students (although not all will be motivated by the idea). The Centre for Sustainable Designs site (www.cfsd.org.uk) is useful to find examples that can be used to illustrate a lesson or converted into an exercise. Exercise – We find that the example (Spangler, Hoover and Dyson) is a very good basis for a group exercise or discussion. This issue for discussion is why Spangler never became wellknown, Hoover dominated the market for so many decades and why Dyson has replaced Hoover as the leading manufacturer of vacuum cleaners. 75 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Exercise – Similarly, the box on aircraft ‘stealth technology’ can make a good exercise. In particular, it brings out the idea of technical possibilities versus market acceptance. Exercise – An exercise that can be used with experienced students is to get them to draw the funnel of development (as described in the text), in reality, for their organisation. Rather than a simple and logical smooth funnel, how does it actually look in your organisation? 76 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 9 Topic – The process of operations strategy – formulation and implementation Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 9 of Slack and Lewis Cole, R.E.

Why is sustainability of alignment so important? What is the formulation process trying to achieve? What are the practical challenges of formulating operations strategies? If you are familiar with the first and second editions of this text, you will notice that we have changed the way in which operations strategy ‘process’ is discussed. In the first edition, the three stages of operations strategy process in the first edition were identified as • Fit (or alignment) • Sustainability • Risk In the second edition we compressed the first two stages (fit and sustainability) into one chapter and we made the risk issue part of the final chapter on implementation. Nevertheless, if you are comfortable with the ‘fit, sustainability, risk’ model you may wish to introduce it at this point. Now, in the third edition (and in response to user feedback) we have developed a simple stage model that moves from formulation, to implementation, monitoring, and finally, control. Possible lesson elements Exercise – The ‘line of fit’ model shown in the text is particularly important to illustrate the nature of alignment and it is therefore worth trying to structure an exercise of some sort round this. One can do this either by using a case study (The Dresding Medical Case in the extra cases section of this guide) is ideal for doing this. Alternatively, for experienced students, one can ask them to draw on examples from their own organisations. Exercise – This chapter contains the second part of the story of Dell Computers. At the time of writing, it is not possible to say exactly how market and competitor changes have impacted on Dell’s business model. It is nevertheless a good basis for a discussion and/or exercise irrespective of how things actually work out. The way to do this is to make sure that you are upto-date on Dell’s current competitive position (simply search on the Internet for this). Then examine the reason for Dell’s success initially and ask the students to identify the main reasons why Dell’s business model came under threat. Also, get them to distinguish between sheer scale (as companies get larger they find it more difficult to remain agile) and the appropriateness of the business model as such (customer needs change and therefore operations models must change with them). Teaching hint – The ‘innovators dilemma’ and the idea of disruptive technology always goes down well as a discussion point in class. One could ask students to identify examples of disruptive technology. Some may identify the internet itself as a disruptive technology, others might raise the idea of technology developments in communications or entertainment (MP3 78 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual compression is an obvious example in entertainment). Also ask them to assess the response of the incumbent companies to these threats. A good example is the way established record companies have used Digital Rights Management (DRM) to attempt to protect their intellectual property (or more accurately, failed to protect their intellectual property). Exercise – Either the Hill or the Platts-Gregory models can be used with experienced students as a basis for analysing their own organisations. If you decide to do this, it is important to stress that both these approaches may need to be ‘customised’ to the specific circumstances of their own company or organisation. 79 © Nigel Slack and Michael Lewis 2012 Operations Strategy TEACHING GUIDE 10 Topic – The process of operations strategy – monitoring and control Reading(s) (This section includes the relevant chapter of Slack and Lewis plus any additional reading that may be particularly helpful) Chapter 10 of Slack and Lewis Pearce, J.A.

How does organisational context affect implementation? How does methodology affect implementation? How can project management affect implementation? How can participation affect implementation? Possible lesson elements Exercise – The idea of using the line of fit model to illustrate risk is a particularly useful one. Back in the first edition of the text we used two examples (Virgin Trains and Renault) to illustrate the idea of operations related risks from lying above and below the line of fit. Although these examples need updating, they can still be used in class with some success. Exercise – Utilise the fact that newspapers continually refer to failures. Just go through any of the broadsheets papers and cut out examples of failure. Give a separate one to each group of students and ask them to analyse their failure in terms of why it happened, what the consequences were and what could be done to prevent it occurring again. Teaching hint – If your institution has an off-air recording licence, it is easy to find plenty of failure examples on television. Some of these might be catastrophic failures such as major accidents, others may be alleged service failures such as those dealt with on consumer programmes. Either way, showing a video clip as a prelude to discussion can usually prompt some interesting learning opportunities. Exercise – On residential courses try combining business with pleasure by showing a movie in the evening which demonstrates failure. The next morning this can be used as a case study. An ideal example is the Apollo 13 movie staring Tom Hanks. It is a great example of failure and failure recovery. All manner of lessons come out of this including the importance of improvisation, the use of fail-safe devices, the concept of balancing risks, the role of creativity in failure problem solving and so on. Exercise – The study guide associated with this chapter contains an exercise where students are asked to choose one statement from two that best reflects what they feel is appropriate in their own organisation. This can be used to start a discussion on the role of central operations as described in the text. Exercise – Stakeholder management is a particularly important part of implementation. Ask student groups to identify some major changes that they have heard of (either in their own organisation or those that have been described in the press) and identify the type of stakeholders that will need to be included in the implementation. Ask them to use the power-interest grid to classify these stakeholder groups. 81 © Nigel Slack and Michael Lewis 2012 Extra cases and the topics covered in each case 82 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Case Ch 1 Ch 2 Ch 3 Ch 4 Ch 5 Ch 6 Ch 7 Ch 8 Ch 9 Ch 10 Introduction Perform -ance Subs for strat Capacity Supply Technology Improv -ement Pro/Serv develop -ment Formulation and Implementation Monitoring and control Hagen Style ∗∗ ∗ ∗ ∗ ∗ Dresding Medical ∗ ∗∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗∗ Call-Us Banking Services ∗ ∗ ∗∗ Freeman Biotest ∗ ∗∗ Zentrill ∗ ∗∗ Bonkers Chocolate Factory ∗ ∗ ∗ ∗ ∗ ∗ Aztec Component Supply Ontario Facilities Equity Management ∗ ∗ ∗ ∗ ∗ ∗ Project Orlando at Dreddo Dan’s ∗ ∗ The Focused Bank ∗ ∗ ∗ ∗ ∗∗ ∗ ∗ ∗ ∗ ∗∗ ∗ ∗ ∗ ∗ ∗ ∗∗ ∗ ∗ ∗∗ ∗ Geneva Construction and Risk ∗ ∗ ∗∗ Clever Consulting Saunders Industrial Services ∗ ∗∗ The Thought Space Partnership Customer Service at Kaston Pyral ∗ ∗ ∗∗ Primary focus of case ∗ Secondary focus of case 83 © Nigel Slack and Michael Lewis 2012 ∗ ∗∗ ∗∗ ∗ ∗ ∗∗ ∗ ∗ HAGEN STYLE ‘Hagen Style’ was one of the most successful direct marketing companies in North America, selling kitchen equipment, tableware, containers, small gadgets, salad bowls and so on. Founded around 40 years ago as a manufacturer of plastic kitchenware, it originally sold its products through department stores. However, soon it had evolved into a pioneering direct marketing operation which sold its products (only about half of which were now manufactured by itself) through a network of local representatives. Working from home, they were recruited to service a geographic area, usually within a one-hour drive. In total the company had almost 10,000 representatives although only around 70 per cent of them were ‘active’. Representatives would sell from door-to-door or at places of work, community centres, clubs, etc. and consolidate their orders on a weekly basis. Hagen would receive their orders, pack and dispatch them so that the representatives could deliver to their customers in less than one week. Most representatives still mailed their order to Hagen using pre-printed forms and pre-paid envelopes, some faxed their orders and a growing number posted their consolidated orders by Internet. Whereas many representatives now used the Internet to place orders, most of their customers were not amongst those who would have access to, or be comfortable using, this way of placing orders. Most of Hagen Style’s products were ‘value’ items of reasonable quality with standard rather than innovative design. Orders were received at one of Hagen Style’s two distribution centres (staggered through the week so as to smooth demand on the centres). Both centres, one in Atlanta near the company’s head office, the other, in New Jersey, used the same processes, perfected over many years. First, the representatives’ orders were keyed in to the company’s information system (or checked if they came through the Internet, mistakes by representative were still common using this medium). This information was fed down to the warehouse where each representative’s order (usually containing 20–50 individual items) was packed. Much of the packing process was standardised and automatic. A standard sized box was automatically loaded on a moving belt conveyor and, as it proceeded down the belt, automatic dispensers, each loaded with one of the higher selling products, deposited items in the box. At the end of the belt, if an order was complete, as around 45 per cent were, the box would be automatically check weighed (to ensure that no items had missed the box), the delivery note inserted, filler put in the box to prevent damage in transit, sealed and addressed. Those boxes which needed additional items packing (usually these were less popular or large items which would not fit the automatic dispensers) were automatically routed on to a manual line where operators would complete the packing process. At the end of the packing lines were the loading bays where boxes would be loaded onto the trucks for their journey to the representatives. The packing sequence fed down to the warehouse was calculated so as to ensure that all boxes for a certain area arrived at the correct loading bay just in time for dispatch on the correct truck. Jed Mayer, Hagen Style’s vice president of distribution, was proud of his distribution centres. ‘It is no exaggeration to say that we run one of the slickest order fulfillment operations in the world. Years of investment and improvement have gone into perfecting it. Certainly industry benchmarking studies show that we are significantly superior to similar operations. We have lower costs per order, far fewer packing errors, and faster throughput times from order receipt to dispatch. Our information system, transportation and warehouse people have together created a great system. Our main problem is that the operation was designed for high volumes but the direct marketing business using representatives is, in general, on a slow but steady decline’. 84 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Jed’s anxiety over future business was shared by all the company’s management. Direct selling using door-to-door representatives was increasingly regarded as an old fashioned market channel. Traditional customers were moving towards using catalogues, TV shopping channels, or just buying from supermarkets and discount stores, most of which now stocked the type of products in which Hagen Style specialised. Recently even Hagen Style, bowing to the inevitable, had started selling a limited range of its products through selected discount stores and was planning to sell through a catalogue operation. It reckoned that it could maintain, or even improve, its product margins selling through these channels. The company reckoned that around 35 per cent of its business would be distributed this way within 5 years. The problem was, ‘how to distribute their products through these new channels?’ Should they modify their existing fulfillment operation or subcontract the business to specialist carriers? And what would happen to their distribution centres?’ This posed a problem for Jed. ‘Although our system is great at what it does, the downside is that it would find it difficult to cope with very different types of order. Moving into the catalogue business will mean dealing with a far greater number of individual customers, each of whom will place relatively small orders for one or two items. Our IT systems, packing lines, and dispatch arrangements are not designed to cope with that kind of order. Fedex or UPS would be great at that kind of delivery, but we couldn’t do it with our existing operations. We would have the opposite problem delivering to discount stores. There, relatively few customers would place large orders for a relatively narrow range of products. That is the type of job for a conventional distribution company, of whom there are many who would just love to provide us with their services. So, basically, we just can’t service either of the new market channels from our existing operations. We either invest in new distribution operations, which would be expensive and we don’t have the right experience, or we subcontract these activities. As far as I am concerned, it would be better to concentrate on what we know. For example, I have been talking with Lafage Cosmetics who sell their products in a very similar way to our traditional business. They have always been envious of our fulfillment operation and have indicated that they would be willing to subcontract most of their order fulfillment to us. Also, as our own traditional representativebased business declines, we will have the capacity to move their volume over to our centres. I am sure we could still get profitable business by utilising our distribution skills for the substantial number of companies who still need our kind of service. It’s either that, or give up on distribution entirely and subcontract everything’. 85 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – HAGEN STYLE In many ways this simple example encapsulates the whole dilemma of operations strategy for many companies. ‘Should we simply follow the market and make sure that our operations resources are capable of meeting market requirements? Alternatively, should we recognise the possibly unique strengths which we have and try to find parts of the market where we can exploit those strengths?’ Here is a company whose market is changing. Not dramatically perhaps, but in a clear enough way for the company to realise that their existing way of selling is probably not viable in the long term. Analysis Hagen Style became a successful company through exploiting a niche in the homewares market, namely selling value items through direct sales ‘representatives’. These company representatives either sell door-to-door, or exploit their own social networks, or organise sales through societies, clubs and places of employment. They provide a customised and high contact sales experience even if the products themselves are from a standard range. Their products represent ‘good value’, which is a combination of relatively low cost and reasonable quality. They are neither stylish nor innovative but of relatively conservative design. The representatives also serve another important function, consolidating orders into a weekly ‘batch’ which they place with the distribution centre. Orders are then placed in a staggered sequence throughout the week to smooth demand levels at the distribution centres. Although most consolidated orders are still posted to the distribution centre, internet-based ordering is increasing. Delivery takes place to customers, usually within one week of ordering. However, the traditional direct sales method of selling using representatives is seen as being in steady decline. The company is already selling some items through discount stores and is planning to sell through a catalogue operation (and presumably will need to have a business-to-consumer internet sales operation very soon). Their ‘order fulfilment’ operations include processes which receive orders, check them, pack the orders using some combination of automatic and manual packing, check/weigh the order, send to the dispatch bay and distribute through its fleet of vehicles. It does this in two distribution centres – one in Dortmund and the other in Munich. Considerable investment has been made in the information technology which integrates order information with the physical process of packing the orders and in the automatic packing technology. This has resulted in an order fulfilment operation which is significantly better than other similar operations in the industry. The company’s processes are efficient, low cost, make fewer errors and have faster throughput times than equivalent operations elsewhere. However, the operation, although good at serving the company’s existing markets, would be less effective at serving slightly different sales requirements. 86 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Variety of items per order wide narrow Existing ‘effective’ capability Lafage Cosmetics requirements Existing ‘effective’ capability Catalogue customers small Store delivery Number of items per order large Hagen Style – Comparison of new demands placed on the order fulfilment processes by potential new business opportunities The diagram above illustrates the capabilities and requirements of the company’s order fulfilment processes in terms of the number of items per order (i.e. how big the order is) and the variety of items per order (the number of different products contained within a single order). Relative to the company’s existing capabilities, customers ordering through a catalogue would be likely to place smaller orders with fewer separate items than the company’s representatives. Stores that sell the company’s products on the other hand only sell a limited range but would be selling them in higher volume and placing orders less frequently. If the company take on responsibility for distributing to Lafage Cosmetic’s customers, as has been suggested, the demand placed on the company’s processes would be very similar to their existing services to their sales representatives. 87 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The figure below summarises some of these points in terms of the company’s operations resources and its market’s requirements. Operations Resources Market Requirements • 2 x distribution centres • Cost efficiency • Fast delivery • Traditional ‘representative’ sales channels declining in popularity •As above plus • wider range of requirements • more demand fluctuations? •New channels • catalogue • internet • discount stores • State-of-art packing and information technology • Processes ‘fine tuned’ to traditional ‘representative’ sales channels • Good at what it does • cost efficient • fast throughput Hagen Style – Operations resources and market requirements What is the question? Put simply, this company faces the dilemma of moving with its markets and therefore changing its operations resources to fit its new markets, or alternatively, seeking out new markets which will allow it to exploit its operations-based superiority. Which is more important to it, its markets or its operations capability? This question is linked to the more fundamental one of, ‘what does the company think it is really good at?’ Are its keys skills in understanding the needs of those parts of the market who buy its products? Alternatively, is its key skill the ‘order fulfilment’ business of translating customer orders into fast, high quality and low cost delivery? What are the options? Option A – do nothing, stick with existing services to existing customers through existing channels, minimise any new business involving new channels. Option B – accept that the market is changing and adapt the company’s processes and resources so that they will be capable of serving new channels to market. Option C – limit or abandon new channels to market and seek out new business opportunities (such as the Lafage Cosmetics business) which allow the company to concentrate on what it does best. Option D – try and develop an operation which can serve all parts of the market including existing channels, subcontracted business from Lafage, store delivery and catalogue customers. 88 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Evaluation Option A – the main advantage with Option A is that it requires no action, no disruption and no investment. This makes for a comfortable life, at least in the short term. It may also be a perfectly sensible option to pursue. If the company is not able to afford to invest in either its resources or its markets, there may be little alternative to this option. Moreover, the company may conclude that none of the other options are worth pursuing because of the risks involved in each. The problem, of course, is that the company’s current markets are in long-term decline. So, with demand volume declining, the operation will find it increasingly difficult to maintain the efficiency of its processes. At lower levels of utilisation, costs per order shipped will undoubtedly increase. The issue for the company then becomes one of managing decline in the business. Option B – this option is the ‘popular’ solution to this company’s dilemma. The market is clearly changing, so why not adapt the operations processes to match these changes? If those new markets are both profitable and sustainable this may very well be the best way forward. We do not have information on either the profitability or sustainability of either of the two new market channels mentioned in the case (catalogue/internet-based selling and selling through retail stores). What may give cause for concern is the fact that the company has moved into both these markets as a reaction to the decline in its traditional direct selling channel. In other words, the objective seems to have been to maintain volume rather than increase profitability. So the first issue is to try and assess the profitability of potential new markets. The second issue is how easy it would be to change the company’s operations to match new market requirements. A large part of the company’s efficiency seems to be the result of using automated packing technology. As with most automation, this is likely to be efficient at performing a specified task, but less good at performing a range of tasks. Currently, it will be configured to pack orders with a range of items per order and a range of different items within the order. Both the catalogue customers and store delivery orders require a different combination of number and variety of items per order. More significantly, each of these new markets is different from each other. The technology may be able to be configured for any one of the markets, but it probably could not serve two or three at the same time. Option C – this option is unlikely to require much, if any, change to the company’s existing processes. However, it does depend on both the likelihood of gaining the Lafage Cosmetics business, the size and sustainability as well as the profitability of the Lafage business, and the possibility of gaining other similar business. In other words, how big and how profitable is the market for the kind of services which match Hagen Style’s current capability? Option D – in some ways this is an ideal option. Multiple channels for their own products and subcontracted business from other companies both increases the amount of business for the company and provides a hedge against any one of the markets being served by the company declining. Of course the major problem is that it compounds the operations-based challenge of meeting multiple market requirements. 89 © Nigel Slack and Michael Lewis 2012 DRESDING MEDICAL Since founding her company over 10 years ago, Dr Laura Dresding had never been either so anxious or so enthusiastic about the future of Dresding Medical (DM). The company had enjoyed considerable success, both financial and in terms of market share by designing, manufacturing and supplying a range of medical equipment to hospitals and clinics throughout the USA. Starting with cardiovascular devices, their range expanded to include neurological stimulators and monitoring diagnostic devices. ‘Success has come largely from our research and development culture. Although around 50 per cent of our total manufacturing is done in-house, our core competence is an ability to understand the needs of clinicians and translate those into our products. We were among the first to expand the range and functionality of this type of equipment and integrate it with sophisticated diagnostics software. Admittedly our products tend to be relatively highly priced and we are coming under some cost pressures, but because of our technical excellence and our willingness to modify equipment to individual customer needs, we avoid too much pressure on our prices’. DM’s operations planning and control systems had been relatively informal. A team of specialist sales technicians discussed individual clinical needs with customers and wrote a ‘product specification’ for manufacturing to work to. Around 70 per cent of all orders involved some form of customisation from standard ‘base models’. Manufacturing would normally take around 3 months from receiving the specification to completing assembly. This was not usually a problem for most customers; they were more interested in equipment being delivered on time rather than immediate availability. The manufacturing department was largely concerned with assembling, integrating and (most importantly) testing the equipment. Most components were made by suppliers who had been doing business with DM for some years and were capable of accommodating their strict quality requirements and their need to customise components. Laura Dresding knew the strengths and weaknesses of her manufacturing operations. ‘Manufacturing is really a large laboratory. It is important to maintain that laboratory-like culture because it helps us to maintain our superiority in leading edge product technology and our ability to customize products. It also means that we can call upon our technicians to pull out all the stops in order to maintain delivery promises. However, I’m not sure how manufacturing, or indeed the rest of the company, will deal with the new markets and products which we are getting into’. Dr Dresding was referring to a new generation of ‘small black box’ products which the company had developed. These were significantly smaller and smarter devices which were sufficiently portable to be attached to patients, or even implanted. For example, a cardiac defibrillator which, when necessary, can jolt the heart into maintaining a healthy rhythm and diagnose how and why the heart has gone wrong. Other products included drug delivery systems and neurological implants. All these new products had two things in common. First, they took advantage of sophisticated solid-state electronics and second, they could be promoted directly to consumers as well as to hospitals and clinics. Dr Dresding was under no illusions about the significance of these changes. ‘On the market side we have to persuade health care and insurance companies to encourage these new devices. They may be expensive in the short term but they can save money in the long term. We are hoping that customer pressure will act in our favour. What is more problematic is 90 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual our ability to cope with these new products and the new market they are addressing. We are moving towards being a consumer company, making and delivering a higher volume of more standardised products where the underlying technology is changing fast. We must become more agile in our product development. A new base model currently takes over 3 years to develop; we cannot afford to develop the new products in any more than 12 months. Also, for the first time, we need some kind of logistics capability. I’m not sure whether we should deliver products ourselves or subcontract this. Manufacturing faces a similar dilemma. On one hand it is important to maintain control over production to ensure high quality and reliability; on the other hand, investing in the process technology to make the products will be very expensive. There are subcontractors who could manufacture the products for us, they have experience in this kind of manufacturing but not in maintaining the levels of quality we will require. We will also have to develop a ‘demand fulfillment’ capability which will be able to deliver products at short notice. It is unlikely that customers would be willing to wait the 3 months our current customers tolerate. Nor are we sure of how demand might grow. I’m confident that growth will be fast but we will have to have sufficient capacity in place not to disappoint our new customers. We must develop a clear understanding of the new capabilities which we will have to develop if we are to take advantage of this wonderful market opportunity. Who knows, it could become the first step in transforming the whole company. I see no reason why, eventually, we should not move into running health management clinics ourselves. We are already developing technologies that could monitor patients at a distance. We can even re-programme implanted devices, without surgical intervention, based on our diagnostic systems. I know all these actual and potential changes suggest that we need to develop separate types of operation to service the different markets, but I am really reluctant to destroy the culture of technical excellence we have built up with our current operation’. 91 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – DRESDING MEDICAL This case illustrates an operations strategy dilemma which occurs in most companies at one time or another. It treats a company which is entering a related but different market. The issue is how to think through the implications of these changes as they affect the operations resources within the company. This involves understanding how the company satisfies its current markets, understanding the requirements of the new markets and understanding the implications for the operations function of serving both markets. Analysis DM supplies a range of medical equipment including cardiovascular devices, neurological stimulators and monitoring diagnostic devices to hospitals and clinics. More recently a new generation of standardised products has been developed, designed to be attached or even implanted into patients. Whereas the original products were multi-functional and sophisticated pieces of equipment which almost always had to be customised to the requirements of individual clinics and hospitals, the new range of products could be marketed more directly to consumers as well as being sold through healthcare organisations. The major differences between the current and new generation of products can be summarised as follows. Current product range • Multi-functional devices. • Most delivered products are customised from a ‘base’ product. • Fifty per cent of manufacturing done in-house (especially final assembly and test). • Prices (therefore presumably margins) high but some cost pressures starting to build up. • Product development lead-time around 3 years. • Order lead-time around 3 months. • All manufacturing and delivery (and usually design) is ‘to order’. • Manufacturing operation is ‘laboratory style’. • Sales staff have to be technically very proficient, talk to medics on equal terms, so presumably ‘relationship’ is important in achieving sales. • Long-term relationships with suppliers because of strict quality and customisation requirements. 92 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The new range of products • More limited and targeted functionality. • More of a ‘consumer’ type of product in so much as users can be targeted directly. • Products still supplied through clinics, who would usually charge the customer for the products. Prices are presumably considerably cheaper than current products but expensive on a per customer basis. • Need to persuade healthcare and insurance companies that devices can save money in the long term. • Volumes higher and products more standardised than current range. • Underlying technology changing fast so frequent product updates likely. • New product development lead-times need to be less than 12 months. • Delivery logistics capability will be needed. Production control will be important to maintain quality and reliability levels. • Higher volume process technologies rather than laboratory style one-off manufacture. • New suppliers need to be developed who can maintain quality levels. • Unsure of what will constitute an acceptable order lead-time. • Uncertain growth in demand for products but likely to be fast. • Seen as important to meet demand, especially early in product life cycle. From an operations perspective the differences between the market requirements for the current and new product ranges can be illustrated by examining each of the performance objectives (quality, speed, dependability, flexibility and cost). In this case though it is necessary to ‘unbundle’ these performance objectives slightly, it is important, for example, to distinguish between specification quality and conformance quality. Similarly, here flexibility could be split up into customisation, delivery flexibility and volume flexibility. The figure above shows the profiles of the two product groups. Note that these profiles must be considered, to some extent, approximations. They are derived from the information that is either stated explicitly or inferred in the case. In practice such an analysis would be debated with the company’s management in order to discover the more subtle differences and similarities between the two product groups. 93 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Quality (specification) Cost Quality (conformance) X X X Delivery flexibility X X Speed X X X Volume flexibility Dependability Customisation Current products New products Polar diagram illustrating the relative importance of the performance objectives for the current and new products What is the question? As is sometimes the case in operation strategy, one has to dig a little in order to find the real question in this case. Indeed, identifying the question is, in itself, a major issue for this company. The question is certainly not whether to change. Dr Dresding seems convinced that the market opportunity is too good to miss. However, it may be worth debating the risks associated with moving into the new product range. Certainly it would require very different capabilities from the company’s operations. Dr Dresding is even thinking of changing the nature of the business in a more radical way by moving downstream into ‘managed healthcare’ services. What is in doubt though is whether Dresding will want to continue to market the older products in the long term. However, we have no information on this, or even information that would allow us to make a judgement as to whether it would be wise. The assumption must be that the company will serve both markets, at least in the short to medium terms. Given this, the question seems to be, ‘How do we make the changes to the operations which the new product will require?’ Beneath this is the question of how to serve both markets with two different ranges of products at the same time. 94 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What are the options? If the company is indeed going to develop, manufacture and sell both the current and new range of products, one can frame the options it faces in terms of how distinct to make the processes which design, manufacture and sell each product range. So, the options could be stated in the following manner. Option A – design, manufacture and sell both ranges of products using the same processes. Option B – design, manufacture and sell the two ranges using entirely separate processes (by setting up a separate operation, site or even company). Option C – design, manufacture and sell both ranges of products with some processes shared and some separate. This means that, in effect, there are an infinite number of options available to this company. Of course, there is not sufficient detail given in the case to attempt any definitive answer. Nevertheless, by thinking through the operations implications of the new product range, it should be possible to assess how different the operations which satisfy this new market need to be from existing operations. If they are relatively similar then this would imply that something close to Option A could be considered. On the other hand, if both market requirements and the operations resources which would need to satisfy them are very different for the two product ranges, this would imply that something close to Option B should be considered. Evaluation Evaluating the degree of difference between the two product ranges is an ideal opportunity to explore the operations strategy matrix, which is described in Chapter 2. The matrix is essentially a descriptive device. It acts almost as a checklist by prompting links and associations between the requirements of the market (stated in terms of performance objectives) and the nature of the company’s operations resources (categorised into the four decision area categories outlined in Chapter 2). 95 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Performance objectives Quality (spec) *** Quality (conform) ** ** * Dependability * * * * *** ** Speed ** * Delivery flex ** * Volume flex *** Customisation Cost * * Capacity Lab style manufacture easy to change very important medium importance capacity incrementally *** * * some importance * ** * Supply Network 50% of activities in house * Market Competitiveness Resource Usage *** Process Development Technology and Organisation Low process technology (but high product technology) R&D, Mfg. and Sales all share common knowledge base. Incremental new product development Decision areas Current product range The first operations strategy matrix describes the current state of the company. Specification quality and customisation have already been identified as key market requirements. Specification quality is achieved primarily by the close liaison between research and development, sales and manufacturing, as well as the diagnostic and testing skills within manufacturing. Hence the importance is given to the intersection between development and organisation and specification quality. Development and organisation similarly affects the company’s ability to customise its products. In fact this is closely related to specification quality and again provides an important intersection. Of secondary, although still significant, influence is that between the company’s long-term supply partners and its ability to produce customised high-specification products. Note that speed of delivery is not seen as at all important according to the case study. The second matrix describes the fit which will be required between market requirements and operations resources for the new range of products. We have already seen on the polar diagram earlier that the two product ranges have somewhat different market requirements. Most notably conformance quality for the new product range is particularly important (devices implanted within the body are better if they keep going). Also volume flexibility, to cope with demand uncertainty, becomes important whereas customisation is not at all important. Furthermore, speed in both of delivery and new product development, not currently an issue, becomes fairly important. The overall picture (again this is evident from the earlier polar diagram) is of a market where many different aspects of competitiveness are important rather than one or two key factors only. Although there is some room for debate on this, conformance quality and cost are probably particularly important aspects of market requirements. Conformance quality, as 96 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Resource Usage * *** ** ** * ** * *** *** *** ** * Market Competitiveness Performance objectives Quality (spec) ** Quality (conform) *** Speed ** Dependability ** Delivery flex * ** Volume flex Customisation *** Cost *** Capacity May need to be adjusted quickly very important medium importance depending on demand *** * * some importance * Supply Network Process Development Technology and Organisation New supplies Needs will be needed investment in volume / developed processes R&D, Mfg. and Sales less interdependent. Faster time-tomarket needed Decision areas New product range with the old range, will be influenced by development and organisation issues such as the liaison between the different functions. In addition, now it is also influenced by the capabilities of the process technology which will need to be brought in to manufacture the new products. Cost, previously not an important issue, is also likely to be affected by the efficiency of the process technology, but is possibly most affected by getting capacity decisions right. Too much capacity and excess costs will occur; too little capacity and the company will not be insufficiently volume flexible to meet uncertain and/or fluctuating levels of demand. Although it is a matter of judgement, the two operations strategy matrices do seem to be significantly different. The way in which capacity is managed, supplier networks are managed, process technology is developed and the development and organisation of the company’s infrastructure are all likely to be different for the two different product ranges. Capacity Current product range New product range The laboratory-style manufacturing set-up and the flexibility between functions imply that capacity is relatively easy to change. People, because they share a similar technical knowledge, can be moved between tasks as demand varies The higher volume production using process technologies with fixed capacity limits will mean that changes in output level will involve larger increments of capacity change. There is more risk of getting capacity levels wrong and greater cost consequences of doing so 97 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Supply network Currently suppliers provide components while customised assembly and testing is performed in-house. Most suppliers have been with the company a long time. Presumably relationships are well developed A new set of suppliers will need to be contracted. The companies which supply the components for the new product range are unused to the exacting quality standards demanded by Dresding’s markets Process technology It seems that process technology is relatively general purpose and low tech. Laboratory-style manufacturing processes are need to deal with the high variety implied by customisation The standardised nature of the new range and higher volumes mean that, to be cost efficient, automated process technologies will be needed. The company has no previous experience with such technologies Development and organisations There is a close relationship between the primary functions of research and development, manufacturing and sales. All share a common technical knowledge and work together on developing base products as well as customising products for individual customers. New product development has traditionally taken up to 3 years! To some extent the three functions will each have a more demanding task. If R&D get product designs wrong then they cannot be customised to compensate for any flaws in designs. Manufacturing need to concentrate on getting the capacitydemand balance right and keeping costs low. Sales and marketing now have to thin in terms of market segmentation and promoting products to a wider range of end users. The challenge will be to keep the three functions together organisationally. Also, new product development must get considerably faster 98 © Nigel Slack and Michael Lewis 2012 ‘CALL-US’ BANKING SERVICES ‘Call-Us’ Banking Services (CUBS), a direct financial services company offered a telephonebased banking service. Originally a regional savings and loan company with a small network of ‘bricks and mortar’ branches, they had expanded and developed into a direct banking operations which offered three types of financial product. The first and dominant product group was conventional retail banking. This service offered the normal range of savings and check accounts together with direct debit and payment facilities. The second product group was loan services. This was divided into retail loans, who offered a service to retailers wishing to provide their customers with credit facilities, and personal loans, where individual customers applied directly for loans. The third and newest product group was insurance offering both automobile and home contents insurance. This latter product group was branded differently to the other products and advertised its services separately. The company’s operations were centred around five call centres. Three of these were devoted to ‘account management’ for the retail banking services, one was devoted to loan products and one dealt exclusively with insurance products. All five call centres were in different locations within the region. Account management activities for banking services consisted of simple debit and credit transactions which moved money between different accounts. Customers could phone in at any time of the day or night and conduct their transactions. Demand at any point in time was fairly predictable, especially during the daytime. Demand during the night hours was considerably lower than in the daytime and also less predictable. ‘Most of the time we forecast demand pretty accurately and so we can schedule the correct number of employees to staff the work stations. There is still some risk of course. Scheduling too many staff at any point in time will waste money and increase our costs while scheduling too few will reduce the quality and response of the service we give’.(Peter Fisher, Operations Director) In the loan product call centre the department which processes calls from retail customers was only staffed during normal retail opening hours. But during those hours it was important that sufficient capacity was provided to deal with retail customers calls. Peter Fisher explained, ‘This is very competitive market. If a salesperson in a showroom phones in to arrange a loan for a customer and we don’t answer within two or three rings, the salesperson will simply dial another company and we will have lost the business. Because of this we tend, if anything, to over-staff the department, especially during critical sales times such as Saturday morning’. Once contact was made by the retail store, the customer’s details were keyed into the system which automatically checked them against a credit rating agency’s database. Credit rating agencies are specialist suppliers of information who assess the credit worthiness of individual customers. Loan companies, such as this division of CUBS, purchased services from such agencies. Some agencies, for a higher fee, will guarantee faster and more detailed credit assessments. CUBS were currently considering whether to purchase this enhanced service. Other ways of improving service to ‘retail’ customers were being considered by Peter Fisher. ‘Recently we have been experimenting with installing our own computers into retailers’ showrooms. This would allow a salesperson to enter their customer’s details and links directly and simultaneously to the credit agency and our own systems. It could provide a much faster service for retail customers and would tie them into our company, but it would take considerable investment to install such systems in all our customers’ showrooms’. 99 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The personal loans department in the loan call centre operated very much like the account management call centres. The service was provided 24 hours a day and provided services both to its own banking customers and anyone else who cared to apply for a loan. Similarly, the insurance products call centre operated round the clock and was proving very successful. Because it was a new service, all the technology and ‘multifunction’ information systems were designed specifically to support its operations. ‘We had the advantage of not having to cope with different generations of information systems. Everything is new. This also means that our system response times are fast and we can devote more of our time to providing a more intimate service for the customer. We can also ‘cross-sell’ car insurance to home contents insurance purchasers and vice versa’. Peter was, overall, pleased with the way in which his operations had improved since the company ‘went direct’. However, he felt that a more systematic approach could be taken to identifying improvement opportunities. ‘I need to develop a logical approach to identifying how we can invest our time and money into improving the various aspects of operations performance. We need to both reduce our operating costs and maintain, and even improve, our customer service. At the same time the company, after investing huge sums into reshaping its operations, needs to be careful how it invests further in operations improvement’. More specifically, Peter had been asked to comment on a proposal put forward by the CEO of the bank, Richard Dayton. He was increasingly concerned about the financial position of the bank. Even though this was essentially healthy, the considerable investment in the bank’s operations had heightened the need to recoup the investment through lower operating costs. Peter fully understood Richard’s concerns, but was less sure of his proposal. ‘Richard wants us to consider merging the various divisions of the bank’s operations together. The Marketing and Sales departments would remain separate and focused on their particular markets, but Operations would be put together as one large ‘service provider’. The justification for this is the economies of scale which would result from a single large Operations division. Richard reckons that we could save 3–5 per cent of our current costs. Given that our profits are a little less than 10 per cent of revenue, this is very significant. What worries me is that the benefits of having our existing focused operations divisions are less easy to quantify. I need to decide how to response to Richard’s proposal’. 100 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – CALL-US’ BANKING SERVICES Analysis Figure 1 shows three of the (probably many) trade-offs within Call Company’s operations. The first is the trade-off involved in how staff are scheduled on an hour-by-hour basis. This in fact is the normal trade-off implied in any sort of waiting line system. Scheduling more staff to be on duty than is normal guarantees a fast response time to sales persons calls. This in turn increases the likelihood of gaining extra business and therefore revenue. However, it does mean that there is also an increased likelihood that staff will be under utilised and therefore operations costs will be higher. Reducing the number of staff on duty will reduce costs but may increase response time and therefore reduce revenue. Response time Utilisation of staff Operational cost of credit information Speed and quality of information 1st trade-off 2nd trade-off Staff scheduling in retail loans Level of service purchased from credit agency Operations cost and speed of service Capital investment in ‘retail’ system 3rd trade-off Range of services possible Investment in multifunction system Retail loans onsite investment 4th trade-off Insurance IT system investment Figure 1 Three trade-offs in the Call Centre example The second trade-off mentioned in the case concerns that between investing in a higher level of service from the bank’s supplier of credit information. For a higher fee (and therefore cost to the bank) both the quality and speed of credit assessments can be increased. The trade-off here is between operational cost and the level of service given to customers. However, if the increased quality of credit-worthiness information results in fewer inappropriate loans, then this could recoup some of the cost. 101 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The third trade-off mentioned concerns the possibility of installing the company’s own computer terminals into retailers’ showrooms. Allowing a sales person on-site in the retail customers shop to enter information directly into the system would reduce costs (because the customer would be performing tasks previously performed by the bank’s own staff), increase the speed of response (by cutting out one link in the chain of information) and potentially tie the company into using the bank’s services (because it will be convenient for retail staff to enter customer information once for their own systems and the bank’s). However, the capital investment involved would be substantial (although no precise figure is given in the case). The fourth trade-off illustrated in Figure 1 concerns the insurance call centre’s decision to invest in a relatively sophisticated, multifunctional computer system. This involves a high level of capital expenditure in a state-of-the-art system, but does allow the company to offer a wide range of services as well as allowing the possibility of cross-selling. Both of these abilities increase the likelihood of the company gaining extra revenue. What is the question? According to Peter Fisher, the operations director of CUBS, the question is, ‘How to develop a logical approach to operations improvement?’ The prior analysis has shown how some of the improvement issues for CUBS’ operations can be articulated in terms of trade-offs. In fact, the case describes all its trade-offs in terms of ‘repositioning’. That is, something must be sacrificed in order to gain benefits elsewhere. So, utilisation of staff must be sacrificed if the company is to give better response rates to their customers, more money must be paid to the credit information agencies if the speed and quality of that information is to be improved, extra capital investment must be provided in retail customers locations if costs and quality are to be improved, sophisticated multifunction computer systems must be installed to provide a wide range of services, and so on. An alternative approach is to ask the question, ‘What would it take to improve one aspect of performance without penalties elsewhere?’ Even more ambitiously, ‘Is it possible to gain benefits all round without any sacrifice or even lack of benefit in any aspect of performance?’ A conventional capital budgeting or cost accounting approach would see the company’s decisions in terms of the first question, i.e. ‘How much reduction in one aspect of performance would it take to improve another aspect of performance, and is it worth it?’ The paradox here is that, in spite of describing things in terms of repositioning the trade-offs within his operation, he is actually more interested in overcoming them. Hence his statement, ‘…we need to both reduce our operating costs and maintain and even improve our customer service. At the same time the company, after investing huge sums into reshaping its operations, needs to be careful how it invests further in operations improvement…’. What are the options? Of the four trade-offs discussed in the case, three are still up for discussion while one seems to have been settled. The decision which has already been made is to invest in a new multifunctional system in the insurance call centre which allows call centre staff to offer a range of services and cross-sell products, supported by the new system. So, service levels and revenue-generated activity has been enhanced at the ‘cost’ of capital investment. As for the other three trade-offs, while it is perfectly sensible to take an ‘accounting’ approach to costing out whether it is worth changing the relative positions of the various aspects of performance 102 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual through investment or changes in operational practice, it is also worth exploring the possibility of overcoming the trade-offs. Staff scheduling in retail loans The trade-off here is between staff utilisation (and therefore costs) and response time to customers. Scheduling a large number of staff gives great response times but lousy staff utilisation (and therefore high costs). Scheduling too few staff to be on duty means that they will be well utilised (low costs) but it also means that at times customers will be waiting too long for a response. In fact this is a classic ‘waiting line’, or ‘queuing’ problem. Indeed there are algorithms devised to ‘solve’ it. A trade-off approach, however, would ask the question, ‘What could we do to minimise the effect of the trade-off?’ For example, would it be possible to make a relatively small payment to some staff who lived locally to be ‘on-call’ at particular periods. Then, if demand seemed to be building up to a higher level than forecast, they could be called at home and brought in to staff the centre. This may improve response times without as higher cost penalty as allocating them to a full shift. While this solution retains some elements of trade-off, it also, at least partially, overcomes the trade-off. Another way of overcoming the trade-off would be to improve forecasting methods. It would be at least worth checking if forecasts could be improved. Trade-offs and focus One strategy level trade-off which is not mentioned in the case but is clearly implicit in the way the operation is described, is that between the cost of running the whole operation and the specificity of service offered to support the bank’s different products. The bank has five call centres, three for retail banking services, one for loan products and one for insurance products. To that extent it has adopted a policy of ‘focus’. The call centres are focused on a particular market and a particular set of operational activities to support that market. An alternative operations strategy for the company would be to pool its call centre capacity. This could be done by investing in ‘call switching’ technology. This would, in effect, introduce a further ‘macro’ trade-off between the expense of investing in sophisticated call switching technology which allows calls to be diverted between different centres depending on demand on one hand, and utilisation of call centre staff on the other. Without investing in this system the company would not have to find the investment capital but would incur higher operational costs because at some times staff in one centre would be fully utilised with some customers waiting unacceptably long periods, while in other centres staff may be waiting with no calls to take. So, for a given level of service this is a trade-off between finding the capital to invest in a switching system or incurring the ongoing processing costs of under utilisation of staff. 103 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Specific B Superficial Ideal performance A Quality of service Ideal performance A Quality of service Specific B Superficial Limited Range of services Broad High Low Cost of providing services Figure 2 Currently, the focused nature of the company’s operations implies a concave trade-off curve. Figure 2 illustrates two trade-offs in this way. The first trade-off is that between the quality of service offered in terms of how specific advice can be, first against the range of services offered and second against the cost of providing those services. The company is currently at position A. If it attempted to pool its capacity in order to save costs and took no other action, its quality of service would suffer significantly because staff and systems would not be properly equipped to answer the enquiries associated with a wider range of services. In effect, the company need to make their operations more flexible or more ‘general purpose’. They could do this by providing training, adapting on-screen information systems, etc. This would result in a more conventional convex trade-off curve as shown in Figure 3. Specific C Superficial Ideal performance A Quality of service Ideal performance A Quality of service Specific C Superficial Limited Range of services Broad High Low Cost of providing services Figure 3 Increasing the range of services would still impact on the quality of service but less so. The company’s performance would move to position C on Figure 3. Presumably what the company would then attempt to do is to modify its systems further and improve training and development so that the convex trade-off curve is expanded outwards closer to the ideal performance area as shown in Figure 4. 104 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Specific D C Superficial Ideal performance A Quality of service Ideal performance A Quality of service Specific D C Superficial Limited Range of services Broad High Low Cost of providing services Figure 4 105 © Nigel Slack and Michael Lewis 2012 FREEMAN BIOTEST INC1 Process Line Configuration BRAYFORD BI-LINE 8 Capital cost $5,900,000 $8,800,000 Processing costs Fixed: $150,000/mth Variable: $750/kg Fixed:$400,000/mth Variable: $600/kg Design capacity 1,050 kg/mth 98% ± 0.7% purity 1,400 kg/mth 99.5% ± 0.2% purity Quality Manual testing Automatic testing Maintenance Adequate but needs servicing Not known – probably good After-sales services Very good Not known – unlikely to be good Delivery Three months Immediate Table 4.7 A comparison of the two alternative process line configurations Freeman Biotest was one of the largest independent companies supplying the food-processing industry. Its initial success had come with a food preservative, used mainly for meat-based products, and marketed under the name of ‘FBXX’. Other products were subsequently developed in the food colouring and food container coating fields, so that now FBXX accounted for only 25 per cent of total company sales, which now was slightly over $100 million. The decision The problem over which there was such controversy was related to the replacement of one of the process lines used to manufacture FBXX. Currently, two such process lines were being used; both had been designed and installed by Brayford Corp., a process equipment manufacturer. It was the older of the two Brayford lines that was giving trouble. High breakdown figures with erratic quality levels meant that output level requirements were only just being reached. The problem was: should the company replace the ageing Brayford line with a new Brayford line, or should it commission another process line, the ‘Bi-line 8’line, that would be manufactured by a relatively new company, Bi-Line Inc. V.P. for Technology had drawn up a comparison of the two units, shown in Table 4.7. The body considering the problem was the newly formed Management Committee. The committee consisted of the V.P. for Technology and the Marketing V.P., who had been with the firm since its beginning, together with the V.P.’s for Operations and Finance, both of whom had joined the company only 6 months before. 1 Source: Based on Rochem Ltd., Slack, N., S. Chambers, and R. Johnston (2007) Operations Management, 5th edn, London: Financial Times Prentice Hall. 106 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What follows is a condensed version of the information presented by each manager to the committee, together with their attitudes to the decision. The Marketing Vice President Currently, the market for this type of preservative has reached a size of some $50 million, of which Freeman Biotest supplied approximately 48 per cent. There had, of late, been significant changes in the market – in particular many of the users of preservatives were now able to buy products similar to FBXX. The result had been the evolution of a much more price-sensitive market than had previously been the case. Further market projections were somewhat uncertain. It was clear that the total market would not shrink (in terms of volume) and best estimates suggested a market of perhaps $60 million within the next three or four years (at current prices). Although the food preservative market had advanced by a series of technical innovations, ‘real’ changes in the basic product were now few and far between. FBXX was sold in either solid powder or liquid form, depending on the particular needs of the customer. Prices, however, tended to be related to the weight of chemicals used. Thus, for example, the current average market price was approximately $1,050 per kg. There were, of course, wide variations depending on order size, etc. 'At the moment, I am mainly interested in getting the right quantity and quality of FBXX each month. I’m worried that unless we get a reliable new process line quickly, we will have problems. The Bi-line 8 line could be working in a few weeks, giving better quality too. Furthermore, if demand does increase, the Bi-line 8 will give us the extra capacity.' The Vice President for Technology The major part of the V.P. for Technology’s budget was devoted to modifying basic FBXX so that it could be used for more acidic food products such as fruit. This was not proving easy and as yet nothing had come of the research, although the Chief Chemist remained optimistic. 'If we succeed in modifying FBXX the market opportunities will be doubled overnight and we will need the extra capacity. I know we would be taking a risk by going for the Bi-line 8 machine, but our company has grown by gambling on our research findings, and we must continue to show faith. Also, the Bi-line 8 technology uses principles that will be used in all similar technologies in the future. We have to start learning how to exploit them sooner or later.' The Operations Vice President The FBXX Division was self-contained as a production unit, located at the smaller of the company’s two sites. Production requirements for FBXX were currently at a steady rate of around 1,900 kg per month. The technicians who staffed the FBXX lines were the only technicians in Freeman Biotest who did all their own minor repairs and full quality control. The reason for this was largely historical since, when the firm started, the product was experimental and qualified technicians were needed to operate the plant. Four of the six had been with the firm almost from its beginning. 107 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual 'It’s all right for some of my colleagues to talk about a big expansion of FBXX sales; they don’t have to cope with all the problems if it doesn’t happen. The fixed costs of the Bi-line 8 unit are nearly three times those of the Brayford. Just think what that will do to my budget at low volumes of output. As I understand it, there is absolutely no evidence to show a large upswing in FBXX. No, the whole idea (of the Bi-line 8 plant) is just too risky. Not only is there the risk. I don’t think it is generally understood what the consequences of the Bi-line 8 would mean. We would need twice the variety of spares for a start. But what really worries me is the staff’s reaction. As fully qualified technicians they regard themselves as the elite of the firm; so they should, they are paid practically the same as I am! If we get the Bi-line 8 plant all their most interesting work, like the testing and the maintenance, will disappear or be greatly reduced. They will finish up as highly paid process workers.' The Finance Vice President The company had financed nearly all its recent capital investment from its own retained profits, but would be taking out short-term loans next year for the first time for several years. 'At the moment, I don’t think it wise to invest extra capital we can’t afford in an attempt to give us extra capacity we don’t need at the moment. This year will be an expensive one for the company. We are already committed to considerably increased expenditure on promotion of our other products and capital investment in other parts of the firm. I accept that there might eventually be an upsurge in FBXX demand but, if it does come, it probably won’t be this year and it will be far bigger than the Bi-line 8 can cope with anyway, so we might as well have three Brayford plants at that time.' 108 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE -FREEMAN BIOTEST INC The provision of capacity cannot be always separated from the characteristics of the technology that provides that capacity. So it is in the Freeman Biotest case. The company has two facilities (known as Brayford lines) one of which is starting to prove unreliable. In any event, the total capacity of the two Brayford lines is only a little greater than current volumes. Given that volume is forecast to increase by around 20 per cent in the next few years, there will be a need to invest in extra capacity if demand is to be fulfilled. Analysis Current sales value of the FBXX product = $25 million Average price = $1,050/kg Therefore annual sales volumes = 25 million ÷ 1050 = 23,809.5 kg per year = 1,984 kg per month The total market for such products has been estimated to grow by around 20 per cent in the next three or four years at current prices. Although the market is becoming more price sensitive, if Freeman Biotest retains its current market share, one would expect monthly volumes to rise to around 2,400 kg over this period. This is greater than the combined capacity of the two existing lines, which is 2,100 kg per month. Any evaluation of which facility to invest in will need to examine both technical and financial capacity criteria. Technical Capacity Criteria The most obvious technical criterion is functional capability, that is can the capacity do the job required of it. Certainly, this criterion can be used as an initial screening test to eliminate obviously unsuitable facilities. But, often, there will be several that ostensibly meet the criterion. It may be that the capability requirements are difficult to define or predict, or that neither of the alternative facilities completely fulfils the requirements. As well as absolute capacity, variation in capability can be important; variation both in the sense of reliability, and the process variability in performance that the facility displays. The relative reliability of alternative facilities is usually difficult to predict in advance of purchase. However, if contractors are prepared to give guarantees then this can alleviate some of the cost of repair although not the inconvenience of the facility not being available. Most processes exhibit some variability in performance and a certain level is normally tolerable. However, if the required capability had tolerances on variation in performance this must be used as a criterion. The range of capability could also be an important factor, that is, how adaptable, flexible or general does the facility have to be? This will depend on how accurately we can predict the future use to which the facility will be put. 109 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Financial Capacity Criteria – Costs Cost is clearly a major financial criterion for choosing between facilities. There are, however, two aspects of the cost of any facility, the initial cost and the total life cycle cost. The initial cost is its basic purchase price. Sometimes, limitations on the amount of capital available could eliminate some alternatives that, although they may be good investments, require more initial capital than the company can afford. The total life cycle cost includes the cost associated with acquiring, using, caring, development, design, production, maintenance, replacement and disposal as well as all the support, training and operating costs generated by the acquisition. Financial Capacity Criteria – Benefits The benefits that accrue from investing in capacity cannot always be described accurately in financial terms, but always indirectly reflect in financial performance. Benefits are usually expressed in terms of profit or savings, whichever is more appropriate to the particular decision. Any sensible measure of benefit can be used provided all alternatives are assessed on the same criteria. The timing of benefits can also be important. A useful method of comparing costs and revenue for various levels of use of a facility is by using cost-volume-profit graphs. Risk and uncertainty Most factors that determine the ultimate pay-off of a facilities acquisition decision are, at the time of the decision, only an estimate. We may have more confidence in our forecast of some of the factors than in others, but few of them will be known absolutely. It is useful in such a situation to have some idea of the sensitivity of the outcome of a decision to changes in the various factors. What is the question? In the short-term, the question is whether to invest in a Brayford or a Bi-line 8 facility. New capacity is required both because one of the current Brayford facilities is failing and because demand is almost filling current capacity. In the long-term, the decision concerns not only the type of facilities that will provide the company’s capacity but also must take into account the uncertainties in the marketplace. Broadly speaking, demand is likely to grow slowly if no product technology breakthrough is achieved, but could grow very quickly indeed if the product modifications are developed successfully. Any short-term capacity solution will need to take into account possible future capacity requirements. 110 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What are the options? Put simply, the options are, a) Invest in a Brayford facility. b) Invest in a Bi-line 8 facility. Technical capacity factors: 1. The Bi-line 8 facility gives more capability if needed (1,400 kg per month, against 1,050 kg per month). 2. The quality levels that can be achieved on the Bi-line 8 facility are better, but this is something of a red herring since the case is quite clear in stating that when the Brayford is working properly it achieves perfectly satisfactory quality levels. This would only be an issue if the marketing plan for the future required higher quality levels. 3. There is limited information about the ease of maintenance of each facility. The likelihood is that the Bi-line 8 will be better, but the Brayford is adequate, that is satisfactory. 4. As regards after sales service, again there is little information on the Bi-line 8, but the Brayford is likely to be better. 5. It could be seen as the maintenance and after sales service factors trade-off between the two facilities, but the Bi-line 8’s plus points on maintenance are based on estimates of performance and therefore are less certain. Financial capacity costs 1. The capital cost of the Bi-line 8 is almost 50 per cent more than the Brayford – a considerable cash difference, but its capacity is 40 per cent higher. 2. Figure 1 shows the cost-volume-profit curves for the two alternative strategies. a) buy another Brayford. b) buy a Bi-line 8 (and use it first, bringing in the Brayford when demand exceeds 1,400 kg a month). 111 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual $US 4m Revenue 3m 3 Brayford facilities 2m 1 Bi-line 8 facility 1 Brayford facility 1m 150000 Current volume 1000 2000 3000 Monthly volume (kg) 4000 Figure 1 Cost-volume-profit curves for two alternative capacity strategies 3. From Figure 1: Up to 1,050 kg a month the Brayford option has lower costs. Between 1,050–1,400 kg a month the Bi-line 8 option has lower costs. Between 1,400–2,100 kg a month the Brayford option has marginally lower costs. Over 2,100 kg a month the Bi-line 8 will generate more profit (even assuming that the old Brayford facility will be worth operating). It is evident that the level of profitability depends on the view that the company takes over future sales levels. A very pessimistic view (less than 1,400 kg a month) or a reasonably optimistic view (2,000–2,400 kg a month) favours the Bi-line 8 option. A very little growth marginally favours the Brayford. 4. If we take an optimistic view based on a doubling of sales due to a successful modification of the product, the decision then involves a third and fourth facility. Several combinations 112 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual of the two facilities then become possible, but it seems likely that the company would stay with the type of facilities that it decided to buy at this point in time. In some ways the long-term capacity issue is simpler than the short-term one. Several facilities are likely to be needed in the event of a successful modification to the product. It is therefore useful to examine the operating costs associated with each facility when working at full capacity. Brayford cost at full capacity Cost per kilogram Bi-line 8 cost at full capacity Cost per kilogram = = = = $150,000 + $750 × $1,050 $937,500 $937,500 ÷ $1,050 $892.86 = = = = $400,000 + $600 × $1,400 $1,240,000 $1,240,000 ÷ $1,400 $885.71 The Bi-line 8 provides a lower cost solution although the difference in cost is relatively small, around 1 per cent. Nevertheless, a 1 per cent difference on a $5 or $6 million production cost may still be regarded as significant by the company. Other factors 1. The spares issue is worth mentioning. A mixture of two types of facilities doubles the spares that the company would have to carry and also doubles the quantity of maintenance knowledge that the firm would have to ‘carry’. 2. The effect of introducing new technology into the production system must be recognised. In this case, it would involve some new training to use the Bi-line 8, but in the long run it would de-skill the jobs of the people operating them. 3. If demand does indeed grow rapidly with the modification of the product, one must consider the dynamic problem of increasing capacity as demand increases. The usual capacity planning problems will then be faced, viz: a) Whether to lead or lag demand. b) Whether to go for small capacity increments (Brayford facilities) because these can be more readily used to tailor capacity to demand. 113 © Nigel Slack and Michael Lewis 2012 AZTEC COMPONENT SUPPLIES The senior management team at Aztec Component Supplies knew that they were facing a decision crucial to the future of the company. A plastic injection mouldings manufacturer, they had for the last 20 years specialised in providing industrial mouldings for domestic appliance manufacturers. They were especially adept at moulding relatively large components, such as the outer casing for carpet cleaners. Large components were difficult to make to the high levels of tolerance and finish which customers demanded. Because of this ability they had increasingly focused on the few large customers who were willing to pay their prices. Five years ago, 12 customers accounted for around 80 per cent of Aztec’s sales, now 3 customers accounted for over 90 per cent of sales. The decision concerned an approach which had been made to them by their largest customer, the Desron Corporation. One part of Desron was already their largest customer’s with around 65 per cent of their output. Desron now wanted Aztec to become a sole supplier for a wider range of their larger components. It would, in the first instance, be a 3-year deal whereby Aztec would devote manufacturing cells for each component type exclusively to supply Desron. Although Aztec would not be prevented from dealing with other customers, the amount of business Desron was promising would initially be 5 per cent more than their current total sales and (according to Desron) could double within 5 years. Because Aztec would be manufacturing parts currently made by other suppliers the total variety of parts would increase by around 40 per cent. Prices would be held at current levels in the first year but then would be reduced by 5 per cent per year. Aztec would be responsible for reducing costs in line with price reductions (average cost savings at Aztec had averaged between 2 and 3 per cent per year in the last few years). If Aztec accepted the deal it would also mean them purchasing some new larger machinery to cope with the increased proportion of physically large parts. Ethan Condos, Aztec’s CEO, did not see this as a problem. ‘We need to replace many of our machines anyway. This provides us with the stimulus to do it and our calculations indicate that the deal would give us a good return on the investment. Investment isn’t the problem, it’s the risks of doing the deal which worry me. How do we know that we can cope with the increased variety? We will need to increase the flexibility of our manufacturing operations to cope with this variety, while at the same time reducing costs and maintaining quality levels. And can we achieve a minimum of 5 per cent annual cost reduction? It’s higher than we’ve ever done before. They will help us by providing their own engineers to reconfigure our production system but that will mean exposing ourselves to their scrutiny. I’m nervous about that, the next thing they will be wanting is to examine our financial accounts. Also, what if they ditch us after 3 years? If we accept this deal we cannot keep much of our other business. Just coping with the Desron business will mean us expanding by 5 per cent. Once we have dropped our other customers I doubt if we could get them back easily. Most of all, are we prepared to act as a servant to such a large corporation? Are we ready to put up with so much interference in our business? They are talking about putting their own quality people and production planning people in offices in our plant! As part of the deal they are also insisting that we abandon our MRP (Material Requirement Planning) system and use the more modern ERP (Enterprise Resource Planning) system which they use. They are also insisting that we lease the ERP system from an Applications Service Provider (ASP)’. (Applications service providers hold computer applications such as ERP systems, together with dedicated data bases on their own servers which their clients access using internet-type technologies). 114 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Alice Chang, the Purchasing Vice-President of Desron, was particularly keen that ‘single source’ suppliers, such as Aztec might be, outsourced their planning and control effort using ASPs. ‘Getting our suppliers to use ASPs is particularly important for us. It encapsulates what we are trying to do with sole suppliers. First, we want them to use compatible systems to ensure seamless co-ordination of material flows between their plants and ours. Second, we don’t want to get into negotiations every time we update our systems. We can do a deal with the ASPs for suppliers to update their own systems at relatively low cost at the same time as we update. Third, there needs to be far more transparency around planning decisions with our suppliers. We don’t want to get into plastic injection moulding ourselves, that isn’t our business, but we want to ensure as smooth a supply of parts as if their operation was an integral part of our plants. It is difficult to understand why they are hesitating in accepting this deal. We both agree that, providing they can keep reducing costs, they will be overall more profitable and get better return on assets under the new deal. Also they will have a chance to participate in, and directly influence, our success on which they themselves ultimately depend. For example, they will be expected to take an active part in new product development so they can contribute their expertise in moulding for our mutual benefit. We are not even preventing them from dealing with other companies. I would prefer that they didn’t of course. Just coping with our increased business will be a tough job for them. But they have to understand that unless they make up their minds soon, and fully commit to the deal, we will lose patience. They are not a particularly large supplier, accounting for less than 10 per cent of our purchased parts expenditure. The Desron Group are 50 times bigger than they are, can’t they see we are in a position to help them?’ Ethan Condos was not so sure. ‘Sure it’s a great opportunity but the choice is just too stark for comfort: accept the deal or reject it. Maybe we have to simply be courageous and make a decision one way or the other. If so, we need to fully understand the advantages, disadvantages and, above all, risks of accepting the deal or not. However, I would also like to explore the possibility of some kind of deal which would involve a less radical move than committing ourselves so totally’. 115 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – AZTEC COMPONENT SUPPLIES Partnership, especially between companies of very different sizes, can be something of a mixed blessing. On one hand, closer relationships can lead to considerable mutual benefit. On the other hand, the risks associated with the relationship going wrong can be fatal to both (but especially the smaller) companies. This case explores such a potential partnership. The rewards for both parties could be great, but the risks are also significant. Analysis As a starting point, it is useful to think through the issues contained within this partnership proposal in terms of the changes in market requirements or market position which it implies and the changes to each company’s operations resources (or in the case of Desron, the changes in its supply position). Figure 1 summarises some of the issues under these headings. Aztec Market requirements Operations resources / supply • Desron 65 –105% (?) 200% in 5 yrs (?) • 3-year deal • Prices level year 1 then –5%/year • Guarantees after 3 years?? • Lose other customers for good? • Dedicated cells • Variety Ï 40% Desron • Secure Aztec knowledge of injection moulding for new product development • ‘Seamless coordination’ with Aztec • • Costs need to reduce >5% to maintain profit (historically 2–3% • cost reductions) • Need investment • Desron process engineering help • More (financial?) scrutiny • In-house quality and production planning from Desron • Ditch current systems → ASP Supply quality and planning staff to Aztec Supply process – engineering/cost reduction expertise As far as Aztec’s are concerned, the main impact on its market stance is an increase in Desron business from 65 per cent of its current capacity to 105 per cent of its current capacity. Furthermore, this could increase to 200 per cent of current capacity within 5 years. The deal would also secure Desron business for at least 3 years. However, although prices will be stable in the first year, there is an agreement for ongoing reductions of 5 per cent each year. Also, the deal does not offer any guarantees after 3 years. Just as problematic, Aztec would either have to give up the business from its other customers, with the risk that they would be difficult to win 116 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual back, or expand capacity substantially by around 40 per cent (35 per cent for current business from other customers plus the extra 5 per cent required to meet Desron business). Similar disruption would hit Aztec’s operations resources. They would be required to dedicate manufacturing cells to Desron business and take on all Desron’s work, which implies a 40 per cent increase in variety with all its attendance costs of complexity. The operation would also have to take on responsibility for reducing its costs by more than 5 per cent (in order to guarantee 5 per cent reduction in prices without reduced profits). Historically, it has only achieved a 2 to 3 per cent cost reduction per annum. All this resulted during a period of coping with increased investment. However, Desron would provide process engineering help as well as placing some of their quality and production planning staff within Aztec. Moreover, the operations function would have to ditch its current MRP systems in favour of a new application service provided ERP system. All of this would inevitably mean more scrutiny by their customer. The impact on Desron does not seem to be as great. Desron’s market position may be enhanced because they would have closer access to Aztec’s technical knowledge of injection moulding which could be incorporated in their new product development efforts. However, they would also need to take responsibility for what they call the ‘seamless coordination’ of Aztec’s systems with their own, as well as providing the staff to be based at Aztec’s operations and supplying process engineering capability more generally. What is the question? The question is relatively straightforward in this case. Should Aztec take up the offer to become Desron’s sole supplier of injection moulded parts or should it turn down the offer? Turns down Desron’s offer Accepts Desron’s offer Will Desron find someone else to ‘single supply’? Dedicate to Desron Minimises investment but high vulnerability Retain some other customers Increases investment in capacity but retains ‘safety net’ of other customers Figure 2 Options for Aztec There may also be a subsidiary question namely, if Aztec do take up Desron’s, offer should they attempt to keep any of their other customers or should they dedicate themselves solely to supplying Desron? Figure 2 illustrates these options. 117 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What are the options? The central decision centres around whether the Desron offer is attractive to Aztec and also whether it is really in Desron’s best interests. Let us examine the advantages and disadvantages of the proposed partnership for each company. Figure 3 summarises these. For Aztec, the major advantage is that it guarantees a considerable amount of business. Furthermore, it offers the potential for perhaps substantial transaction costs savings. If they are dealing only with Desron they do not need a sales force as such. All the cost and uncertainty surrounding having to sell their services in the market place is taken away. Similarly, the transaction costs associated with quality control and production planning and control generally will be reduced because Desron are, in effect, taking over responsibility for these on themselves by placing their own staff in Aztec’s operations. Indeed, Desron have undertaken to provide general process engineering expertise to help Aztec with the installation of its new equipment and to help it achieve its cost reductions. According to the case, the deal on paper offers a better return on assets than the current arrangements. Aztec Advantages • • • • Disadvantages • • • • • • Desron More (all?) their business guaranteed Overhead savings because of lower transaction costs – fewer – sales – quality – planning staff needed ‘Better return on assets’ Desron process engineering expertise • • • • 5 per cent reductions ‘Seamless’ coordination Their staff on-site at Aztec Can get out in 3 years if Aztec do not perform Desron could drop them in 3 years No ‘safety net’ of other customers unless they make substantial investment or increase capacity >5% annual cost reduction. Exposure to scrutiny. Cope with +4 per cent variety (cost of complexity?). Cope with new (ASP provided) systems. • • Tied to one supplier (for 3 years) Experience of providing quality and planning staff for Aztec Figure 3 Balanced against this, the deal is only for 3 years initially. Desron could drop them (either because they do not perform or because they have another partner in mind) in 3 years. Also if they retain few, or none, of their other customers, they would not have any safety net of business to grow in place of the Desron business. There is also the risk as to whether they could maintain a greater than 5 per cent annual cost reduction, especially with a 40 per cent increase in variety, while they are getting to grips with the new (ASP provided) systems. Finally, there is Aztec’s reluctance to expose itself to the scrutiny of its customer. 118 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual For Desron the partnership arrangement is not as big a deal. It has the advantage of providing 5 per cent price reductions year on year as well as ‘seamless’ coordination. Moreover, they can get out of the deal in 3 years if Aztec do not perform. However, for those 3 years they are tied to Aztec contractually, so Desron are taking some risk if Aztec fails to perform well. They also have to bear the expense of providing quality and planning staff to manage those functions within Aztec. Key questions Before Aztec decides what to do, they would be well advised to address some particularly important questions. • What happens if they turn Desron down? Are Desron likely to just shrug their shoulders and carry on as before? Alternatively, will they try and seek out some other company who could provide them with a single-sourced supply of components? One would have thought that the risk of Desron looking elsewhere is fairly high. Therefore, unless Aztec can grow its nonDesron business by around 200 per cent before Desron goes elsewhere, it would suffer a fall in volume. All this infers a much more basic question, namely, ‘Does Aztec really have the choice of turning Desron down?’ • What is the value of independence for Aztec? If Aztec becomes a dedicated supplier to Desron it is both losing its independence to try for new business opportunities elsewhere and exposing itself to a possible future decision by Desron to change its supplier arrangements. Is Aztec’s management willing to do this? They are currently in charge of their own destiny. Would they really want to become almost departmental managers for Desron? • What is the outlook for cost savings? Aztec really has to get to grips with understanding the chances of making an excess of 5 per cent per annum cost savings. They need to evaluate to the best of their ability • What would be the extent of transaction costs savings (they can be considerable but might involve sacking people who already perform such jobs as quality and production planning, are they willing to do this)? • What increases in productivity will the new machinery bring? • How much is Desron’s offer of process engineering help really worth to them? They also need to evaluate some of the factors working against cost savings, most notably • • How will the 40 per cent increase in variety affect the costs of complexity? Can the new machinery cope with this variety? • How difficult will the new machinery be to install? What are the dangers of installation causing disruption and extra costs? Can some of the risks be reduced? It is important that Aztec identify what it sees as being the key risks and works out ways to minimise these risks or their impact. For example • Desron volumes drop – traditionally they have simply taken orders from customers like Desron, should they now put themselves in the position of forecasting their customers’ demand levels? 119 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • The new machinery has problems being installed – can we guarantee in advance help from Desron to make sure the machinery goes in smoothly; it is, after all, in Desron’s interests to do this. • The variety proves too costly – start working out now exactly what the variety will mean in terms of its impact on manufacturing and other processes; ensure that the new machinery can cope with this variety. • Have difficulty getting the year-on-year cost reductions – try and formally tie in Desron’s process engineers to share responsibility for doing this, be proactive in organising progress meeting to manage the cost reduction programme. • Desron dumps them in 3 years – ……er…er…. Tricky!….. Get Desron to take an equity stake in the business? 120 © Nigel Slack and Michael Lewis 2012 Zentrill Zentrill were a medium sized chain of fashion women’s apparel retailers with 120 stores, typically relatively small units, in premier High Street locations and shopping malls mainly in California and some Southern states. Their clothes were stylish without being at the extremes of fashion and aimed at relatively affluent customers between the ages of 30 and 60. Gross margins (the difference between what Zentrill pay for clothes and what they sell them for) were undisclosed but, as is common in this part of the fashion market, were very high. Typically an outdoor coat retailing at $1,000 would cost the company less than $200. Zentrill’s designs were exclusive and styled by both in-house design staff and outside consultant designers. All Zentrill’s tailored garments (everything apart from knitwear and accessories) were manufactured by Lopez Industries, a small but high-quality garment manufacturer in Mexico. Traditionally, the fashion retail industry in the northern hemisphere has two seasons; January to July is the Spring/Summer season and August to December is the Autumn/Winter season. Both break points between seasons have traditionally been marked by ‘sales’ where surplus product is marked down for clearance. The proportion of items sold in these sales, or sold through intermediaries (with the Zentrill label removed) could be very high. Typically at Zentrill, only around 50 per cent of items were sold at full price. This caused anxiety to Zentrill’s merchandising vice president, Mary Zueski. 'Achieving only 50 per cent full price sales is obviously an issue to us. Although no worse than most of our competitors, reducing the proportion of discounted sales is the best way to increase our profitability. Sometimes we are left with surplus items because our designers have just got it wrong that season. We can never predict exactly what will sell. However, usually we are quite good at knowing our market. What is more annoying is when a customer walks out of a store because an item which we could have sold to her is not in stock or is not available at that store in her size. Every time this happens hundreds of dollars are walking out of the store with her. Ideally, we would like to be able to promise such a customer that we could deliver the item to her within 24 or 48 hours. Even if we can’t do that, it is important that we sense how sales of different lines are going and flex our order quantities from our manufacturer during the season. Although Lopez is a great supplier in many ways, they do not seem to be very good at being able to change their production plans at short notice. Otherwise, our relationship with them is very good. Our designers like them because they can make almost anything we choose to design, and their quality is excellent, as it should be in our part of the market'. Manuel Lopez, the CEO of Lopez Industries, was fully aware of Zentrill’s views. 'I know that they are happy with our ability to make even the most complex designs to an exceptionally high level of quality. I also know that they would like us to be more flexible in changing our volumes and delivery schedules. We obviously could not deliver within 2 days. The problem of the customer walking out because a size or style is not available in a particular store is caused by the way they manage their own inventory. But I admit that we could be more flexible within the season on a week-by-week basis. Partly, I am reluctant to do this because we have to buy-in cloth at the beginning of the season based on the line-by-line forecast volumes which Zentrill provide for us. Even if we could change our production schedules, we could not get extra deliveries of cloth, nor can we return any surplus cloth to the cloth manufacturers. The problem is that we only deal with high quality and innovative European cloth manufacturers, usually German or Italian. They provide the type of cloth which Zentrill’s designers like to work with. Also, it can give us a competitive advantage because much of the cloth is either lightweight or stretches or has some other characteristic which makes it difficult to machine. 121 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Over the years we have developed considerable skill in machining this type of cloth to high quality standards. Not many garment manufacturers can do that on a mass production basis. Sometimes I think we know more about the characteristics of these cloths than the manufacturers do. Unfortunately, most of our cloth suppliers are very large compared to us, so we do not represent much business for them. Perhaps we should persuade Zentrill to let us use smaller cloth suppliers who would be more flexible?' Typical of the cloth suppliers to Lopez Industries was Schweabsten, a German company that both manufactured cloth and tailored men’s and women’s wear under its own label. Felix Brensten was Schweabstens marketing vice president. 'We compete primarily on quality and innovation. Designing cloth is as much of a fashion business as designing the clothes which it is made into. Around a third of our output of cloth goes to make our own-labeled garments. We do not manufacture these of course; that is done by a whole collection of sub-contract manufacturers. In fact, that is our main problem, finding subcontract manufacturers for our own label products who can cope with high fashion cloths and designs whilst still maintaining quality. The other two-thirds of our output goes to tens of thousands of customers around the world. These vary considerably in their requirements, but presumably all of them value our quality and innovation'. After discussion with her colleagues, Mary Zueski had recently and reluctantly come to a conclusion on the company’s supply problem. 'I guess we can no longer leave everything up to our suppliers. We have to try and organise the whole supply chain more effectively. This will, of course, mean looking at how we manage the part of the supply chain that we control ourselves, from our central warehouse to our stores. But it will also mean taking responsibility for our suppliers, particularly Lopez, and even their suppliers. The question is how to do this? We don’t own them, even if we have some market power over them. How do we begin to identify what each stage in the chain could do for the benefit of the whole chain? More importantly, how do we persuade everyone that it is in their own interests to cooperate?' 122 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – ZENTRILL Sometimes we can only understand the pressures on one operation by putting it in the context of its suppliers’ and customers’ operations. The Zentrill case provides us with an opportunity to look for not only the relationships between the three operations described but also how upstream and downstream relationships affect each other. Analysis The absence of quantitative information in this case does not mean that we cannot examine the relationships between the stages in the supply chain in a systematic manner. Perhaps the most appropriate model to use is that illustrated in Figure 7.5 of Slack and Lewis. This model was used to examine the qualitative nature of supply chain relationships. It enables the search for potential mismatches and misunderstandings between operations at each stage of the supply chain. Figure 1 uses the model to summarise the market requirements and operations performance of the three companies described in the case. These companies are, Zentrill, the fashion retail chain who sell directly to consumers, Lopez Industries, who manufacture the garments for Zentrill and Schweabstens, the cloth manufacturers. Good quality Flexibility during season Wide capabilities Innovation High quality Flexible delivery Quality and innovation Use only very high quality fashion cloth suppliers Good quality Fast availability Flexibility during season Wide capabilities Market requirements What B wants What A thinks B wants What C wants Lopez Industries Garment manufacturers B Schweabstens Cloth manufacturers A How A thinks it is performing Doesn’t know (or care?) What B thinks C wants How B perceives A’s performance How B thinks it is performing Zentrill Fashion retailers C How C perceives B’s performance Operations performance Too small to influence supplier? Great quality, wide capabilities but inflexible within season Great quality Innovation Very inflexible Great quality, wide capabilities but slow and inflexible within season Figure 1 Let us follow the ‘market requirements’ logic through the chain. Zentrill are in the fashion business. They are also an up-market store who sell at high prices with big margins. However, 123 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual only around 50 % of their garments actually sell at full price. The rest are sold for substantially lower margins in sales, etc. From their garment suppliers (Lopez) they demand high quality, they would very much like fast response in order to give high availability if demand for some products is higher than forecast, flexibility to change orders during a season and, more generally, a wide capability to make a wide range of products. Broadly speaking, Lopez Industries seems to have a reasonable appreciation of Zentrill’s stated requirements. They understand the need for high quality and the need to develop wide capabilities. They are particularly proud of their ability to machine difficult cloths such as lightweight cloth. They are also sympathetic to Zentrill’s need for flexibility to change volumes for different products through the season, even if they find it difficult to accommodate such a need. Where they disagree with Zentrill is in the need for fast response. They feel that it is unreasonable to expect a two-day response and believe that the problem could be at least partially solved by Zentrill improving their own inventory management systems. In most industries a company’s interpretation of its customers’ needs would lead it to choose a set of suppliers who could best fulfil those needs. Lopez Industries are more constrained because Zentrill’s designers will have a big say in which cloths they want to use. This means Lopez are required to use the high-fashion German and Italian cloth manufacturers who provide the type of materials appropriate for Zentrill’s designs. What is important for our analysis is that we can see the association between Lopez’s interpretation of Zentrill’s needs and their use of particular suppliers. Lopez’s requirements from its cloths suppliers are for the high-fashion innovation required by Zentrill, high quality and flexible delivery. Flexible delivery would allow Lopez to be more flexible in changing its production levels, which would in turn enable Zentrill to match their stocks with emerging demand. Looking at Schweabstens understanding of Lopez’s requirements (Schweabstens is not the only supplier but is typical of them) we find a major gap. Schweabstens perceives its market as wanting quality and innovation and little else. To be fair, it has a point insomuch as Lopez is not typical of its customers and represents relatively little business. Schweabstens biggest customer is itself, in the sense that it markets its own branded range of garments. Working back down the chain and examining how each link in the chain performs, Schweabsten does not seem to have much idea as to the appropriateness of its own operations performance. For example, ‘(our customers) vary considerably in their requirements, but presumably all of them value our quality and innovation’. Indeed Lopez sees Schweabstens performance as providing great quality and innovation. Unfortunately they also are regarded as being exceptionally inflexible. Yet, flexibility is a prime requirement for Lopez. Lopez uses its inability to persuade Schweabstens to be flexible as the reason for the limitations on its own performance. It believes itself to be too small to influence the cloth suppliers who are usually much larger companies. Because of this inability to influence its own suppliers, Lopez sees its performance as being poor in terms of ‘within-season’ flexibility. However, partly because of its own capabilities and partly because of the high quality of the cloth it gets from Schweabstens, it has excellent quality and wide capabilities. 124 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Zentrill agrees. There is essentially very little mismatch between how Lopez and how Zentrill regard the performance of Lopez Industries. So, in summary, the relationship between Lopez and Zentrill is one characterised by shared understandings, even to the extent of agreeing where performance is less than acceptable. The only discontinuity in the mutual understanding between the companies concerns the ambition to move to a two-day response for urgent garments. However, the relationship between the large cloths suppliers such as Schweabstens and Lopez Industries is much less satisfactory. The lack of flexibility (and the lack of any appreciation that flexibility is important) from the cloth manufacturers is having an effect throughout the chain. Options In this case the options, in terms of what the various players in the chain could do, are not mutually exclusive. There are several potential avenues that could be explored in order to ease some of the problems in the chain. In fact, each stage in the chain could potentially improve its overall performance as follows. Zentrill Zentrill’s contribution to solving the lack of flexibility in the chain is largely to try and reduce their need for fast response. They could do this in a number of ways. • Improve their knowledge of where stock is – the better Zentrill’s knowledge of what stock each store carries, the more likely it is that they can allocate stock appropriately. A combined point-of-sale and stock management system would help them in this respect. • Move stock between retail outlets – it may be worth considering a regular ‘taxi style’ service between stores in a geographic region that could shift reserved stock between branches as demand patterns shift. It could also be possible to accommodate special orders from customers (‘… sure I can get it you Madam, could you come back tomorrow or perhaps we could deliver it to your home?’). With margins as high as Zentrills, there should be sufficient cash to invest in exceptionally high customer service such as this. • Design using more ‘flexible’ cloth – some companies in the fashion garment business try to encourage their designers to use cloths that can ‘work’ on several different garments. Some styles and patterns of cloth will only work on one style of garment. Others could be used on several styles of garment. Clearly, it is an advantage to design garments using cloth that could be used on other garments if the original design fails to sell in the volumes forecast. The dilemma is how to do this without inhibiting the creativity of the designers. Lopez Industries Lopez also have a number of possible ways they could improve supply chain performance. • Make efforts to achieve quick response – although they dismiss the idea of a two-day response level, there are few companies that cannot improve their response rates. Many similar companies have special ‘quick response’ manufacturing cells that are designed specifically to cope with urgent deliveries without disrupting the rest of the operation. 125 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Joint forecasting with Zentrill – perfect forecasts are not possible, however, if they were, they would eliminate the problem. Even though perfection is beyond any forecaster, it may be that a more serious attention devoted to forecasting could help Lopez to schedule more accurately. • Leverage machining expertise with Schweabstens – Lopez Industries may be a very small customer of Schweabstens, but they may be able to persuade the cloth manufacturer to take them more seriously by, in effect, trading their specialist knowledge. Schweabstens admit that they have problems finding high quality sub-contractors to make their own garments. Lopez Industries has considerable expertise, especially with difficult cloths. It may be that they can trade this expertise for more flexible delivery from Schweabstens. • Explore smaller, more flexible cloth manufacturers – if Schweabstens and the other big suppliers remain unconvinced, it may be worth exploring the possibility of using smaller, more flexible companies, especially if they can give similar levels of innovation. 126 © Nigel Slack and Michael Lewis 2012 BONKERS CHOCOLATE FACTORY Chocolate making starts with a series of primary processes to convert milk, sugar and cocoa into thick viscous liquid chocolate. The conching process is a critical element of the primary process, taking fatty powders and, through a shearing action between large contra-rotating rollers which releases fats and disperses solids, to produce liquid chocolate with various controllable physical properties, such as temperature and viscosity. This chocolate is then used at secondary processes; to mould solid bars, to coat biscuits and assortments, and to make speciality products such as Christmas novelties. Bonkers Chocolate, the American division of a multinational candy company, was facing a critical decision over the future of its conching technology. In late 2001, at a meeting of the Bonkers Chocolate Management Committee, discussion centred on the purchase of additional equipment for the Chocolate plant. The Engineering Vice President was proposing the implementation of a new in-house conching technology, whereas the Manufacturing Vice President wanted his $3 million capital application for a fifth conventional conch machine (to provide an additional 25 per cent capacity) approved. ‘I believe that we cannot survive and grow without this type of leading edge development. In my view, the old technology is often barely able to achieve the demands placed on it by the complex new products being dreamed up by our Development people. There are at least six advantages of this technology, not all of which can be evaluated financially: (1) trials indicate that for 50 per cent of recipes, fat content can be reduced by up to 1 per cent without significant changes to flavour or texture. As cocoa butter is expensive, this could give significant savings for some products; (2) the new process gives much greater control over viscosity, allowing more precise coating potentially reducing reject levels on all coated products; (3) conventional conches take hours to clear for a recipe change, during which time the output is a mixture of two recipes, which can, therefore, only be used on the lower quality specification product (usually selling at a lower price). The new conch, in comparison, fully clears all material in less than half an hour, reducing the cost of materials; (4) the new conching process will allow a much wider range of chocolates to be produced, as it can produce to a higher viscosity and to tighter tolerances; (5) we believe that the technology will work at any size from one-tenth to double the size of conventional conches. They can be custom-built for our specific needs; (6) the new conch occupies 1500 square feet on one level, whereas a similar sized, conventional machine occupies 2000 square feet on three levels (total 6000 square feet). These modern and efficient process technologies will be critical in our future developments; Mars and Nestlé are certainly investing heavily in their factories’. Engineering Vice President ‘If we cannot approve the purchase of another conch machine, we won’t meet forecast demand growth for 2002/2, and will be forced to cut back on expansion plans. We already experience frequent capacity problems in the chocolate plant……it is nearly impossible to plan an efficient sequence of production to satisfy the needs of all the secondary user departments. We should purchase another (identical) conventional conch machine to be installed in under 6 months and we would have considerable flexibility…to move staff around the different conches, to plan for any type of chocolate on any conch, and to hold standard spare parts. The new technology conch could take 12 to 15 months to develop, would require different skills in production and maintenance and different planning rules. All this would be too disruptive, just when we need to concentrate on output and new product development’. Operations Vice President ‘I support the purchase of another conventional conch so we get into production by mid-2002; the new technology conch would not be into production until at least 6 months later. But, even more importantly, whilst we know that the small trial machine has made chocolate which the 127 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual tasting panel cannot distinguish from our standard product, there is no guarantee that would be the case for a machine ten times larger. We know that conching is critical in creating our unique Bonkers Bestï›› flavour and texture, so we should take no risks and stick with the process we have been using for at least 80 years. The extra capacity will allow us to go ahead with trials and product launches, which are already being disrupted by capacity and planning constraints’. Sales Vice President ‘We will have to defend existing volume brands by maintaining price competitiveness and quality (taste). The factories must be able to support this by delivering cost reductions but we must also launch new, high quality, high margin products at a faster rate than ever before. I know there are plenty of eager competitors out there ready to erode our shelf space in the convenience stores and supermarkets. Realistically, not all of these new products will be a success and few will ever even reach ten per cent by weight of sales of core products. Taken together however they will be very profitable and provide most of our projected growth. I think you can see why I favour the conventional conch technology. It minimises the fixed-cost burden of extra capacity and ensures low-cost production without any risks associated with new processes’. Marketing Vice President The Engineering Vice President had been expecting resistance from Sales and Marketing but had made attempts to convince Operations of the advantages of the new conch technology. The Finance Vice President also objected, on the grounds that providing the same level of capacity in the new process would cost about $4 million rather than $3 million. It appeared that 2 years of research and trials had been for nothing – but he sprang to the defence of his proposal. ‘I understand your worries but trials of the one-tenth scale conch have been successfully used on our full product range and the tasting panel reports no detectable changes in taste, texture or aroma. I also accept that the new conch could delay capacity by around 6 months and cost a little bit more. The relative annual cost saving of the new technology conch (compared to a conventional conch) in the primary processes would be around $280,000: The labour saving is only small, perhaps half a person or around $20,000. Space savings are estimated by Finance to be worth around $40,000 in opportunity cost. Improved control of cocoa fat content will save the department around $60,000 based on our trials on the prototype machine. The biggest saving is reduced material wastage at changeovers: we expect a $160,000 reduction here. But the big benefits will be seen in the secondary departments, where there will be much more control of coating thickness and less quality and productivity problems. Unfortunately, these savings are much more difficult to predict. Our conventional capital expenditures applications have always had to demonstrate clear departmental cost savings such as reductions in direct labour and associated overheads which result from automation technologies. The opportunities for further automation of high volume production processes are diminishing as the variety of our products is expanding’. The Division’s CEO was alarmed to find that there was no agreed strategy for the purchase of conching capacity but recognised that the decision had to be made quickly and appropriately. 128 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – BONKERS CHOCOLATE FACTORY This example includes a number of different operations strategy issues. It describes a process technology investment decision but also comprises more generic themes. It is equally, for instance, a capacity investment decision and more broadly reflects many of the practical difficulties encountered when formulating strategy. There are different market segments to be served, functional disagreements, short and long-term concerns, varied levels of technical knowledge etc., all of which are classic rescue/requirement reconciliation issues. Analysis Conching is a critical direct (p. 248) material processing technology (p. 249) in the chocolatemaking process. It influences key physical properties of the liquid chocolate and therefore has a major impact on the characteristics of finished products (after passing through a range of secondary processes). Transforming resources (Conching technology, contra-rotating rollers) Inputs (Cocoa butter blends and Chocolate Crumb) Physical material transformation (shearing action, releasing fat, dispersing solids etc.) Outputs (liquid chocolate) These finished products seem to split into traditional products (such as the 80-year-old Bonkers Best) and the trend towards highly volatile (10% success rate) innovative products. In addition, there appears to be (albeit anecdotal) evidence that competitors are investing heavily in process technology and there is a sense that they might ‘fall behind’ if they fail to innovate. As evidence of the significance of the investment decision, the firms’ Management Committee is making the final decision but there is no real agreement amongst the different managers. Engineering had proposed an innovative ‘in-house’ technology, whereas manufacturing wanted capital to purchase an additional 25% conventional conching capacity (a fifth machine). Potential advantages of the new conching technology The engineering department identified, based on trial findings, a number of key advantages associated with the new process technology • Reduction of fat content (for 50% of products) without affecting flavour or texture. This, it is estimated, could create savings of around 60,000 euros. The total annual cost saving in primary processes would be around 280,000 euros. 129 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • All materials can be cleared from the machine in less than half an hour, thus increasing flexibility and improving quality. This provides the biggest potential saving in reduced material wastage at changeovers: they estimate 160,000 euros. • The new process allows a wider range of chocolate products to be produced, as it can produce to a higher viscosity, allow more precise coating and improve quality (narrower product tolerances). • The technology could be custom built to work at a range of ‘scales ’: from 10 to 200% conventional conch size. • The new conch is smaller. It takes up 150 m (on one level), whereas a similar sized 2 2 conventional machine would occupy 600 m (200 m on three levels). This is estimated to be worth around 40,000 euros in opportunity cost. • The labour saving is only small, around 20,000 euros. 2 Potential disadvantages of the new conching technology The manufacturing, sales and finance departments highlighted a number of disadvantages associated with the new process technology compared with purchasing another traditional machine • The slower implementation plan for the new process technology (12/15 months compared with 6 months) means that the firm would fail to meet forecast demand growth (for 1997/8). This capacity shortfall would also mean cutting back on expansion plans. • This delay (and the other disruptions caused by process innovation) would serve to compound existing capacity problems in the chocolate plant – caused by difficulties with sequencing of production. • Standard technology allows for staff flexibility around the different conches and to hold standard spare parts. • Although the trial machine had made chocolate with the traditional taste (tasting panel evidence), there was no guarantee that would be the case for a machine ten times larger. This concern over taste was particularly pronounced for their 80-year-old Bonkers Bestï›› product. • Concern over new product competition meant that any distraction from production (i.e. keep costs low and meet production targets) should be avoided, if at all possible. • The same level of productive capacity using the new process would cost about 4 rather than 3 million euros. From an operations perspective, there are a number ways of interpreting these apparently conflicting conclusions. In a similar way to the analyses deployed elsewhere (Dresding Medical, Hagen Style, Focus Bank etc.), it is possible to examine the implications of, say the traditional and innovative chocolate products, upon the generic performance objectives (quality, speed, dependability, flexibility and cost). Although Bonkers products may not be available, it is 130 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual possible to consider other manufacturers products and compare their traditional (i.e. classic solid bar of milk chocolate) and innovative (i.e. products with peanuts, wafers, formed into particular shapes, calorie controlled) products. In particular, the example can be used to refine the flexibility dimension to include consideration of range, volume and speed/response flexibility. What is the question? As mentioned earlier, this case is illustrative of a number of different operations strategy issues. It is possible to apply the books resource and requirement analyses (OS matrix) but it is also possible to look at other frameworks such as that (designed for manufacturing strategy formulation) proposed by Terry Hill. Likewise the case demands consideration of the impact of adding capacity at different rates and in different scale increments. This ambiguity is actually a good way of getting into the debate and the functional perspectives of the different managers can be used to highlight the various risks and opportunities faced by the company. Regardless of this breadth however, the key question must be, ‘Should Bonkers Chocolate implement their own conching technology solution instead of buying another “off-the-shelf” unit of capacity?’ What are the options? In addressing this process technology investment decision, four options immediately become apparent. Option A – Do Nothing. Delay the decision until market requirements or the viability of potential technological solutions becomes a little clearer. Option B – Yes, they should build on the work completed by the engineering group, take the development risk and implement their own technological solution. Option C – No, they should simply purchase another conventional conching machine. Option D – Yes and No. Purchase another machine to meet short-term demand and continue to invest in the new technology. Evaluation Before addressing the specific competitive options it is useful to develop a richer understanding of the new technology. Using the dimensions and models proposed in Chapter 5 of Slack and Lewis it is possible to define the new conching technology’s (relative to the traditional) characteristics. 131 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Low volume High variety High Loose acuity and Many, separated judgment small units High volume Low variety High Market requirements High COST Low FLEXIBILITY Actual characteristics of current technology (larger scale; less automated; more ‘integrated’) Low SCALE AUTOMATION COUPLING Potential characteristics of new technology (smaller scale/greater scalability; more automated; less ‘integrated’) Integrated Low Few, large, rigid acuity and small units judgment Whilst such technical characteristics might suggest that the new technology is an obviously beneficial investment, the case illustrates how important it is to be able to fully articulate the full range of competitive benefits (i.e. not just rely on cost savings) a technology delivers. This is particularly important when, as per normal, there is considerable uncertainty surrounding the final implementation of the new technology. It is, of course, also possible to apply the market requirements and resource-based analysis. Option A – This has the clear advantage of avoiding/minimising managerial conflict. In effect, the firm could treat the sunken investment costs as having purchased a ‘real option’ that allows them to develop the technology at some point in the future. This means that the firm can wait until residual market uncertainty is better resolved and may minimise the risks associated with the final investment. The challenge is to decide how long it is possible to wait before ‘exercising’ the option becomes worthless (because of competitor action etc.). Option B – This (given the above analysis) is the popular and ‘strategic operations’ (i.e. building advantage through operations-related investment) option. There are clear advantages associated with the potential characteristics of the new technology. In particular, its greater levels of flexibility (quicker changeovers etc.) and control (chocolate coating etc.) appear to be critical if the trend towards a short life cycle, innovative chocolate products come to dominate their market. Moreover, the firm’s conventional capex applications have always had to demonstrate clear departmental cost savings (such as reductions in direct labour and associated overheads); however, the opportunities for further automation of high volume production processes are diminishing as the variety of products expands. It also allows the firm to match 132 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual their rival’s investments and not find itself competing with inadequate operational capabilities. Equally, if the trials prove correct, then the new system should not affect the all-important taste of ‘Bonkers Best’. It is important however to recognise and address the concerns of the other functional managers. Why are they concerned, why do they want a quicker option, what would be the impact of any delay in adding productive capacity. As an illustration of playing ‘devil’s advocate’, consider the investment cost decision. The difference between the figures is essentially marginal between the two purchase (B and C) options (although not when compared with option A) but, if the forecast development costs were twice as big, would the benefits still seem as critical? Several of the frameworks from Chapter 5 of Slack and Lewis (feasibility etc.) could be used to discuss these issues. Option C –The key concern with this option seems to be whether the forecast demand will materialise. If greater emphasis is placed on the uncertainty associated with development (i.e. the implementation actually takes 24/36 months) it could be seen as creating an unacceptable risk of not meeting market requirements. If however, the market uncertainty was seen as the greater source of risk, then this option would be difficult to justify. Some of the arguments for this option (existing skills, interchangeability of staff and mechanical parts etc.) are legitimate but not critical, whereas others (production scheduling, inventory build up etc.) simply reflect poor analysis or poor communication of the benefits by the technology ‘impresario’. Option D – This might seem like the perfect option and in many ways is an alternative real option. It involves (1) deferral of major investment, hopefully allowing market requirements to become clearer and (2) staging of smaller investments, allowing the firm to abandon its development project if some insurmountable technical or market problem emerges. It is important to recognise however, that such a strategy has to be carefully planned and analysed because it also runs the risk of being ‘stuck in the middle’ with respect to competitors. In other words, the firm might be left with a partial technology that is incapable of responding to market requirements or a reasonable sunk cost that delivers no value (except for some salvage value). 133 © Nigel Slack and Michael Lewis 2012 ONTARIO FACILITIES EQUITY MANAGEMENT (OFEM) Facilities management now is a multi-billion dollar business in most developed economies. Facilities management companies offer a range of property management services including basic maintenance, cleaning, fitting and supplying office equipment, heating and environmental services, ‘disaster recovery’ services and increasingly, information technology equipment hosting and leasing. ‘Facilities management is the basic housekeeping of business. It may not be glamorous but it is vital. It has always been done of course, usually in-house by people who often had other responsibilities. As buildings and services became more sophisticated, the provision of even standard office services required more cash and more expertise. Most large companies soon found that companies like OFEM could provide these services better and cheaper. That is what we have to keep in mind as we move into providing more (and more varied) services – we have to be better and cheaper than our customers could do it themselves. If we ever forget that we will be in trouble’. (Guy Presson, CEO OFEM). The Security Division Within OFEM, the Security Division looked after the development and installation of security equipment and systems in client’s property. These included alarm and intrusion systems, security enclosures (safes), surveillance and monitoring systems, and entry security systems. In fact, entry security systems were becoming particularly important for the company. Many firms were increasingly security conscious. As companies became more information-based they felt themselves vulnerable to industrial espionage or threats from individuals and groups dedicated to causing disruption, either for its own sake or to pursue political ends. Entry security systems had the purpose of permitting entry into various parts of a building only those individuals who were authorised to be there. Traditionally this had been done using swipe cards or various kinds of security PIN numbers and codes. ‘Entry security systems are now in routine use. There are very few of our clients who do not want some kind of personnel security system, and they expect us to be able to provide it. Financial services companies have been in the forefront of our customers demanding increasingly tight security. More recently it has been IT-based companies who have made the running in demanding security. Some of our most demanding clients now are those with large web-hosting operations. They demand several levels of security, as a minimum at the “building”, “department” and “machine” levels. In other words, individuals need to be checked for access authorisation as they enter the building, when they enter a particular part of the building, and before they can use an individual terminal to access computer systems. Machine level security has traditionally been provided using encrypted security passwords. However, passwords are particularly problematic because they are either forgotten, written down or even shared. In fact it is not difficult to guess many people’s passwords’. (Mirella Freni, Head of Security Division) 134 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Technological developments The Security Division was facing a period of technological change in so much as several new developments in security technology were starting to emerge. These were affecting both what was known as ‘front-end’ and ‘back-end’ elements of security systems. Back-end technologies were the systems which record, analyse and interpret the data from frontend technology such as swipe cards, etc. These systems enabled companies to know exactly who was where, and when. In addition to the use of such information for security purposes, it could also be used for monitoring employee working hours and so on. Systems were now becoming available which could detect ‘abnormal’ behaviour in staff. For example, if the same swipe card was used to enter a building within minutes of it being used to leave the building, this could prompt an investigation to check that it had not been lost and picked up by an unauthorised individual. OFEM were considering adopting this type of technology. It would mean working closely with systems developers to provide a generic system which could be customised to the needs of individual clients. This would be expensive but the company felt that they could probably charge clients for the extra services this technology would provide. The systems themselves were very similar to those used by credit card companies to detect unusual behaviour but would need some modification. It was estimated that OFEM would need to invest between C$2.5 million and C$3 million over the next two years to have these systems up and running. The revenues from such an enhanced service were difficult to estimate but some within the firm claimed they could be as high as C$1–C$1.5 million per year. It was the recent ‘front-end’ technological developments which were even more intriguing. These involved the application of biometrics – using human features for unique identification. This technology was becoming available commercially for the routine identification of individuals through features such as eye characteristics, fingerprints, voice recognition and even body odour. In particular, fingerprint recognition and iris (the central part of the eye) recognition looked promising. Fingerprint identification was in many ways the simpler of the two. ‘One advantage of using fingerprints for unique identification is that the same system can be used at all levels of security. Fingerprints can allow access to buildings, departments, and can also allow access to an individual machine. Panasonic has already produced some laptops for one life insurance company with a fingerprint reader built in. This means that the security risks of losing a laptop or having it stolen are virtually eliminated. Such technology can also be used for mobile phone security. But fingerprint recognition is not perfect. It can be affected by machine malfunction or changes and damage to an individual’s skin’. (Mirella Freni, Head of Security Division) More exciting in the long run was the prospect of extensive use of iris recognition. An individual’s iris is one of the most uniquely identifiable characteristics and one which does not change over time. Surprisingly, it also works well if the person is wearing spectacles, contact lenses or even sun glasses. ‘This is probably the real technology of the future, it is already being used by some ATM manufacturers to prevent cash machine fraud and there have been trials at several high security establishments. Again, we can use the same technology at building, departmental and machine levels. In fact, machines will become even easier to use. There will no more need for passwords, no necessity to repeatedly enter the same data such as personnel details, it will even be easier to share computers without losing the advantages of security. 135 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Cameras can be built into the screens of computers which will enable them to discriminate between different users with different levels of security clearance’. (Mirella Freni, Head of Security Division) There were however some drawbacks to using iris recognition. Even though it was more reliable than using fingerprints, the general problem of reliability remained an issue. The problem of falsely accepting someone who was not authorised to use a system was not an issue, rather it was the problem of falsely rejecting genuine users. Anything other than a tiny proportion of false rejections would be very irritating to any clients’ staff. Second, the technology, although likely to be widely used in the future, was relatively new to the company. There was the risk that there may be disadvantages which had not yet been thought of. Fingerprinting was a better understood technology. Third, in some companies some staff had proved reluctant to subject themselves to this security. There was still the impression that the technology involved ‘laser scanning’ the eye. This sounds dangerous to most people, though in fact the system did not use lasers but rather simple digital camera-like technologies. Finally, some groups were worried that the technology could be used intrusively to monitor employees’ use of systems, or even levels of staff attention as they worked at the screen. Costs and benefits Both fingerprinting and iris recognition systems would be expensive to develop. It had been estimated that at least C$1 million a year would be needed for the next 3 years, probably a little more than this for the iris recognition systems. In the Security Division’s overall revenue budget of C$15 million this was not necessarily a prohibitive sum, the real problem lay with the uncertainty of any revenue coming from such an investment. ‘Investing in more sophisticated back-end systems will mean extra revenue for us, but it is unlikely that we could charge much, if anything, extra for improved front-end security. There is no real extra service even though there is a higher level of security. I’m not sure that customers would be willing to pay significantly more for this. OK, some of our real security-minded customers may do so, but most won’t. Yet this is the way technology is moving. Certainly our competitors are considering adopting such technologies, and if they are doing it we should be considering it. Also, if we master iris recognition in particular, other business may be open to us, such as the maintenance of ATMs and so on. At the moment the critical decision for us is where to invest our money, back-end? Front-end?, or both? And if we go for new front-end technology, should it be fingerprint based or iris recognition?’ (Mirella Freni, Head of Security Division) Even though Mirella Freni knew that revenue projections for any of the options were uncertain, she had asked her marketing colleagues to come up with some kind of estimate. This had not been a popular request. Marketing had declared that any estimate would be highly problematic and could only be taken as a ballpark indication of future revenue. Others in the division were openly sceptical of Marketing’s ability to forecast levels of sales of its existing services, never mind services which were entirely new to the market. Mirella, however, was determined that the decision should be based on some quantifiable data. When the estimates were received they surprised Mirella (see Exhibit 1). 136 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Exhibit 1 – Revenue projections for the three investment opportunities Yr 0 Yr 1 Yr 2 Yr 3 Yr 4 Yr 5 Back-end analysis 0 0 CS1m C$1.5 C$1.5 C$1.5 Front-end fingerprint recognition 0 0 0 C$0.5 C$1.5 C$1.7 Front-end iris recognition 0 0 0 C$0.3 C$1.5 C$2.5 Note: figures are in C$ millions at today’s prices ‘It seems the more they (Marketing staff) thought about the possibilities of the front-end options, the more enthusiastic they became. Personally, I find these estimates optimistic, but my Head of Marketing is now saying that he is willing to stake his reputation on the figures. But whatever one thinks of the estimates, we need to make a decision soon’. (Mirella Freni, Head of Security Division) 137 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – ONTARIO FACILITIES EQUITY MANAGEMENT (OFEM) This case is discussing investments which a facilities management company could make in its process technologies. In this case it is concerned with customer processing and information processing technologies. It calls the customer processing technologies ‘front-end’ technologies and the information processing technologies ‘back-end’ technologies. One back-end investment and two front-end investments are discussed. Analysis The case describes three separate potential investments in process technology. These are • an enhanced back-end system which allows for sophisticated information processing, including routines which can enhance security. • fingerprint recognition technology which would eliminate the need for bar code scanners or the use of security codes. • iris recognition technology which again overcomes the limitations of traditional security systems and is potentially more reliable than the fingerprint recognition. These investments are not mutually exclusive insomuch as the company could invest in all three. However, two things could prevent investing in all of the new technologies, first, all are expensive and it is unlikely that the security division could justify such investment, second, to some extent fingerprint recognition and iris recognition are alternatives to the current technology. Given this, perhaps the best approach which the company could take would be to evaluate all three options and prioritise them. To try and structure an analysis we can use the three criteria of; • feasibility – can we do it? • acceptability – what benefits do we get from doing it? • vulnerability – what risks do we run if we do it? 138 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 1 shows a summary of the three investments. Feasibility Back-end systems • • • Front-end fingerprint recognition • • • Front-end iris recognition • • • Acceptability Vulnerability Already have less • sophisticated back- end systems in place. • Analytical software similar to that used elsewhere. • C$2.5–C$3m investment required over 2 years. Confidence in future revenue streams. Crude payback on investment 3.7–5 years. Could customise service to clients needs. No in-house experience • of this technology. Other industries using it • – computer manufacturers. Investment of ≈ C$3m • over 3 years. Essentially a • defensive move. Unlikely to generate • new revenue streams but could protect existing business. Payback?? May not prove sufficiently reliable. Competitors may invest in same technology. No in-house experience • of this technology. Some other industries starting to use it. Trials at some very high • security facilities. Partly defensive, • partly opens potential new business in very high security at ATM areas. ‘Technology of the • future’. Payback?? More reliable in use than fingerprint recognition but less well developed. Intrinsically more risky technology? • • • Low risk from process technology itself. Risk of competitors getting ahead with ‘higher security’ customers if this is only investment in new technology. Figure 1 Back-end systems investment This potential investment is basically an upgrading of current back-end systems to incorporate more sophisticated analytical software and provide more functionality. The investment is fairly substantial (C$2.5–C$3 million over 2 years). However, the software is similar to that used in the banking and credit card industries. Presumably the estimates of investment required will be reasonably accurate. The company also have confidence in their ability to use the technology to provide services at higher margins. The major risk is not from the technology itself but rather from investment in this technology draining funds from investment in front-end technology development. Nevertheless, overall, this seems to be a relatively safe and attractive investment. Front-end fingerprint recognition This type of technology is already in place in some industries, most notably the computer industry. However, OFEM have no experience of using it. It is likely that the company will have less confidence in their estimate of how much investment will be needed to develop this technology. Currently they believe it to need C$3 million investing over 3 years. They believe that other companies are already likely to move into this technology. Therefore, adopting it must be seen as essentially a defensive move. Furthermore, it is unlikely to generate new revenue stream, although it could protect existing business. The payback from such an investment is 139 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual difficult to estimate, though is unlikely to be very large. One problem already identified with the technology is that it may not prove sufficiently reliable in practice. The ‘false negative’ problem of legitimate users being rejected may seriously undermine clients perception of the quality of service they receive. Front-end iris recognition Again, the company have no in-house experience of using this technology. Also, again, some other industries are starting to use it. Perhaps most encouragingly, there would appear to have been trials at some very high security facilities. This is a similar setting to the one in which OFEM intend to use the technology. The technology itself, although partly defensive, may open opportunities for new business. The two areas mentioned are in the very high security market and in the servicing of ATMs (Automatic Teller Machines). Also, it seems to be regarded more as the ‘technology of the future’. However, as with fingerprint recognition, the payback is uncertain. Although it may open new revenue streams, the investment will be no less than for fingerprint recognition and possibly will be higher. However, in use the technology is likely to be more reliable than fingerprint recognition even though it is less well developed currently. Nevertheless, the technology must be considered intrinsically more risky because of its lack of development. Evaluation To some extent this case is an exercise in balancing long-term and short-term developments in process technology. In the short term, development of the back-end system seems a safe bet. It is not particularly risky and seems capable of creating future revenue streams. It is unlikely that the company could resist making such an investment. However, in the long term, it is the frontend systems which may provide the more significant impact on the company’s competitiveness. Here there is probably a good argument for ‘leap-frogging’ fingerprint recognition and going straight for iris recognition technology. Indeed, iris recognition technology seems to dominate fingerprint recognition in a number of ways. It is likely to be more robust in use, it has already undergone trials in some very high security facilities, so presumably others in the industry regard it as a potentially attractive technology, it can open up new business streams especially in the very high security area which sounds like a new market for the company, it seems to be regarded as having a longer term future than fingerprint recognition technology, and its payback is likely to be better (assuming that the future revenue streams are greater than the extra investment needed). 140 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 2 illustrates where the three process technologies may lie on a ‘process distance – resource distance’ graph. Although approximations, it does illustrate that both front-end technologies are intrinsically more difficult insomuch as they infer greater process distance and greater resource distance than the back-end investment.

Thought Space is supposed to be one of the leading creative companies in this part of the world. Yet we manage to come over as being indecisive and inefficient. We always used to boast that we had the three Cs – creativity, commercialism and competence. We had some of the best minds who were capable of the most creative solutions, we understood the commercial priorities of our clients and we always delivered on time, and on budget. Not in this case. The Cityscope project has been dogged by confusion and problems from the beginning; we ought to rename the three Cs as confusion, criticism and chaos. Nor have we ever had such bad publicity. OK, so it was not an easy assignment. The overall purpose and objectives were never that clear and there was political interference from the start. The city council approved the money but against such opposition that it was always going to be controversial. Also, the sponsors were being leaned on, politically. Some didn’t really want to contribute at all. On top of that, the whole project was managed by committee. Some of them thought it was a kind of theme park, others that it should be a museum, for some it was a performance space, for others an Expo. Yet we can’t blame them entirely. We should have known what kind of project it was. The real point is that we might have been able to offer a leadership role if it wasn’t for our inability to recognise the project for what it was. The different perceptions of each department in the Partnership reflected the differences within the project itself. "Event’s" saw it as a cross between an exposition and a performance. "3D design" saw it as some kind of gallery or museum. "Technical Solutions" thought of it more as a theme park. "Graphics" just saw it as a nuisance. None of them every really worked together. They may be experts in their field but this type of project called for some creative collaboration. It also called for some fast footwork as ideas developed and as the political processes within our client group began to be evident. Relying on a single project coordinator was crazy. Even an experienced guy like Gordon, could not get everyone to pull together. The real point is that large, complex projects like this will soon become our main business. Depending on how you define our assignments, around a third of our business is already heavily cross-functional, we can’t afford to have Tech Solutions pleasing themselves what they develop, Events always seeking high profile business irrespective of the internal chaos it causes, 3D design seeing themselves as the real creative ones and Graphics virtually declaring independence. No, I would scrap the whole functional organisation. We need to form dedicated but temporary teams for each assignment. These could then both integrate the various skills we have and understand the exact nature of the task we are being set. They could respond flexibly and appropriately to each assignment. When not engaged on a particular assignment, staff could carry out some of the more routine departmentally-based work. We are supposed to be one of the most creative partnerships in the business. Why can’t we be creative with our own organisation?' (Caroline Hesketh – Creative Partner) ….one mistake doesn’t mean it’s broke… 'Look, I know we didn’t cover ourselves in glory with the Cityscope project but let’s not overreact. Admittedly, it was not a well-executed piece of work but it’s made to seem worse by the 142 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual fact that a couple of journalists decided to make a story out of us. In reality, we were no worse than any of the other creative agencies who were used on the project. It’s just that our zone attracted more controversy. We were unlucky as much as we were incompetent. It is certainly no reason for totally shaking up the whole organisation. The existing groups work well together. One of the ways we get such creativity out of our people is by hiring very capable minds, letting them mix with other equally challenging individuals and expecting them to hone their skills in the commercial reality of their clients’ projects. It’s the interplay of ambitious, challenging individuals with shared skills which makes for creativity. Most of our clients are still wanting the services of one, or at the most two, of our groups. Graphics and events work largely alone. Tech Solutions and 3D design do work together more than any two other groups, but only about 30 per cent of their work is collaborative. Breaking up the departments would be both profoundly unpopular with most of our staff and risk destroying our experience base. I cannot see why we cannot continue to use the Project Manager idea for the larger cross-functional projects. If Cityscope was a failure it was a failure of project management. It’s the cross-functional project management skills that we need to develop. I know Gordon is experienced but no one could have foreseen the can of worms which this project was to become. Perhaps the real lesson from this is not that we need a new organisation, rather it is that we should be more careful about the kind of assignment we take on, and we need more project management experience. That’s what we need to buy-in. There is plenty of work about which can be done under our existing structure. Why try and fix something that ain’t broke?' (Jeff Siddon – Creative Partner) ….ditch the ‘us and them’ approach … ‘We are all agreed that the last few months have been traumatic for everyone. It was embarrassing and it has damaged our reputation, though I don’t think permanently. Yet it has been positive in some ways. At least it brought us all together for a while when we were fighting a rearguard action to limit the damage and salvage some professional price. All the departments worked together better during that period than at any time I can remember. Also, it proved to us that, whatever the lessons we choose to learn from this incident, we must address the issue of how we work across organisational boundaries. We were forced to do it in order to recover when things really looked bad, and when we were working cross-functionally we achieved real creativity, if only in preventing things getting worse. But let us take this idea further. Most of us agree that the roots of the whole problem lay in the lack of agreement between the various external stakeholders in the project. We can view this two ways. We can say, "OK, no more projects unless we can be sure that the clients’ objectives are clear". To me that’s just running away from the problem. The alternative is to admit that most of our projects, and all of the really interesting ones, have some degree of ambiguity built into them. The real issue is how do we manage the ambiguities and conflicts which are a part of any large, complex (and lucrative) project? What I am saying is that it is not just the internal boundaries we want to breach, it’s the external ones also. In fact both sets of boundaries are related. We can’t get stakeholders involved in an open and creative way unless we can show them the potential which derives from the combination of our various internal skills. Yet we can’t really manage that creative combination of our skills unless we involve the external stakeholders more directly. The solution I am proposing is that we make our own "ideas factory" a living example of what we are capable of. It should be a place where everything from the design of the office space 143 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual through to the way we greet visitors reflects the creative values of the business. Any clients or groups of clients visiting us (and they all should be made to) should feel they are entering an ideas "theme park", a place which excites their vision of what is possible, a place where they can interact with us, where we can understand their various requirements and where clients can use the environment to understand any of their own internal conflicts. I propose that our existing marketing department transforms itself into a "Client Experience" team, responsible for the design and management of the total client experience. This would include deploying our existing, or any new, centres of expertise within the building and organising their work to provide the appropriate client experience while ensuring that our creativity is fully exploited’. (Pauline O’Sullivan, Marketing Partner) 144 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – THE THOUGHT SPACE PARTNERSHIP This case treats a professional service company in the ‘creative industries’ sector. There is relatively little written about professional services, nor are they the subject of many case studies. This is surprising because they are increasingly becoming an important sector in developed economies. In some countries the professional services sector is at least as large as the manufacturing sector. Furthermore, professional services are interesting from an operations strategy viewpoint because they are ‘knowledge rich’. That is, they add value for their clients by developing and deploying knowledge, often by blending different types of ‘technical’ expertise. This is certainly true of those professional services operating in the creative industries. In The Thought Space Partnership case exercise we get two views of the same project. Both agree that the project was unsuccessful but disagree on how to prevent similar problems reoccurring. Analysis Although the case does not provide an explicit description of the company’s current organisational structure, it would appear to be based on a conventional functional organisation with cross-functional project managers. In this sense it is a combination of what Chapter 10 of Slack and Lewis called a U-form organisation and a matrix organisation. Figure 1 shows the company structure. Top Management Events Graphics ..Etc. Project A Project B Project C Figure 1 Some of the ‘functions’ seem to be based on activities that may be close to certain market segments, for example, ‘Events’ presumably means the job of organising and designing corporate events such as trade shows, etc. Others seem to be based around technical skills such as ‘Graphics’. Presumably, there are also more conventional functions such as Marketing and Accounting, even if these are not particularly large. Two departments are described as working largely alone; these are ‘Events’ and ‘Graphics’. Two other departments are described as 145 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual working together for around 30% of their activities; these are ‘3D designs’ and ‘technical solutions’. What is interesting here is the degree to which the conventional functions of the firm, in effect, overlap. Some organisations (especially service organisations) have organisational overlap between the activities of product and service development, marketing and operations. With professional services this overlap is even greater. Figure 2 illustrates this. Product/service development Marketing Marketing (CREATIVITY) Product/service development Product/service development Operations Marketing Operations (COMMERCIALISM) (COMPETENCE) Operations Some manufacturing Mass services Professional services Figure 2 Increasing overlap between operations and the other core functions This explains the comment in the case exercise by Caroline Hesketh that, 'We had the three C’s – creativity, commercialism and competence'. These roughly map on to product/service development (which is the heart of the creative process), marketing (understanding the commercial imperatives of clients) and operations (exhibiting competence in the delivery of services). The implication of such high degree of overlap between the core functions is that any organisational structure will be, to some extent, imperfect. The same structure needs to ensure creativity, present an appropriate external face to the client and deliver a high quality of service. Evaluation From the quotes in the case exercise, it appears that the Cityscope project failed in all three of the company’s core functions. • In terms of marketing, the organisation exhibited an 'inability to recognise the project for what it was'. In other words, marketing’s role of deciding whether to accept the project or not was flawed. There is a suggestion that the seeds of the project’s failure should have been evident to the company from the beginning. Marketing's fundamental task of positioning the company where it could profitably differentiate itself through the application of its expertise was not realised. • Product/service development has the responsibility to devise products and services that fit the client’s needs, are creative and can be delivered. In this case the client’s needs do not seem to have been fulfilled, there is some doubt about the creativity exhibited and whether the project was delivered on time or not, it seems to have caused considerable internal friction. 146 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Operations has the task of delivering the service to specified levels of quality, speed, dependability, flexibility and cost. Presumably it did not achieve this, otherwise the client would have been happier. The two viewpoints expressed in the case articulate two views of how the organisational structure could be improved. Caroline Hesketh puts forward the case for what she calls a radically new sort of organisational structure. This seems to consist of retaining the current departments but in a weaker form and forming dedicated but temporary teams to deal with the large cross-functional projects. Staff from each of the functions would be assigned to a team for the duration of the project and then either be assigned to another team and another project on its completion, or return temporarily to their functional ‘holding area’. It is not clear how clients who required only one department’s expertise would be served. Presumably, by having direct contact with the department as at present. The other view, as expressed by Jeff Siddon, envisages the retention of the current functional organisation but with more effective project management. He sees the failures of the organisation as coming from a weakness in an organisational mechanism that is already in place. It is not the organisational structure which is at fault, he says, but the fact that one part of it is not being made to work properly. Figure 3 illustrates some of the criticisms that were made of the company’s handling of the Cityscope project. These are as follows. • It made us look bad. • The objectives were never clarified. • It couldn’t cope with the external politics. • It couldn’t cope with being part of a total project that was managed by committee. • It did not provide leadership for the total project. • It did not cope with differing internal perceptions of the project. • Departments did not work together. • There was no ‘creative collaboration’. • There was no ‘fast foot work’ response to emerging issues. 147 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Functional organisation with better project management Dedicated temporary teams Made us look bad 9 Objectives never clarified 9 Couldn’t cope with external politics ? ?

Of all the criticisms made of the Cityscope project most would seem to be at least partially improved by using the dedicated temporary team organisation. Such a dedicated team would be better at coping with potentially damaging public relations issues and would stand a better chance of clarifying objectives. The members of the team, after all, are working only on the single project and would see themselves as being held responsible for its success. It would also be better at avoiding different internal perceptions and working together. Other things being equal, it could also respond more flexibly as issues emerged. Whether it would be better at coping with the external politics of the project, managing the external project committee or providing leadership is less clear. Maybe the one area where the functional organisation is superior is the ability to come up with creative ideas. At least as far as the individual technical specialisms are concerned, the in depth knowledge and critique of closely-knit functional specialists may provide superior solutions. However, it may be that the creativity between technical specialisms is more important for this kind of project. It is difficult therefore to justify the current organisation, even with strengthened project management. The nature of large inter-disciplinary projects is such that dedicated temporary teams will generally be superior. Maybe the real question is whether the company sees themselves as moving more into this kind of business. Currently, it accounts for around a third of the total company revenues. If that figure is likely to increase and/or if that kind of business is particularly profitable, then the dedicated team organisation would look even more attractive. 148 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The Future? One organisational form that the company may wish to consider moving towards is the N-form organisation as described in Chapter 10 of Slack and Lewis. Figure 4 illustrates this structure. A word of warning, however. It is unlikely that moving immediately to such a radical structure would be wise for this organisation. It has, after all, only just come to the realisation that its traditional functional structure may be inappropriate. Nevertheless, the N-form organisation is often promoted as being ideal for organisations that need to both nurture their technical competences and cope with a wide variety of market and client needs.

Companies have realised that they do not necessarily have to be physically represented in the country whose market they are serving. Decreasing telecommunications costs have made us all aware that we can get unheard of economies of scale by focusing on large and sophisticated call centres that can serve a whole continent, or even the whole world'. (Lisa Jackson, Customer Service Vice President, Kaston Pyral, US). Kaston Pyral Group (KPG) is an international manufacturer and installer of heating, air conditioning, environmental control and condition monitoring systems. While the company’s products still included electro mechanical devices and (mainly) gas burning heating devices, heat exchangers, etc., increasingly they provided the sophisticated software that controlled and monitored both their own and their competitors' systems. These control systems could be updated independent of the hardware. They could also be integrated with other building and environmental management systems to provide ‘total monitoring and maintenance’ control. This could include remote diagnostics capabilities that allowed KPG’s engineers to spot potential problems even before the customer had noticed. The customer service division of KPG provided customers with a range of services including spare parts supply, maintenance and technical support. Technical support was becoming particularly important because the integration of new KPG systems with ‘legacy’ control systems could cause unforeseen problems. In most markets around the world the division had their own service centres, but also used contract service engineers. Until recently the division also operated call centres in each country in which it operated. The call centres would take orders for spare parts and arrange delivery, investigate billing queries, arrange for regular or emergency repair and maintenance visits and provide technical support for installed hardware and control software. Merging the call centres The customer service division had recently decided to merge its individual country-based call centres into three regional call centres that would cover its three regional markets worldwide. Last year, the call centre in Antwerp, Belgium, had expanded its capacity by five times and had taken over responsibility for all European customer service. A single centre in Kuala Lumpur, Malaysia, was planned to serve the Asian market. Lisa Jackson’s responsibility was to oversee the merger of the North American call centres (previously in New Jersey, Montreal and Mexico City) into a new centre located in Atlanta, Georgia. The changeover to the new centre was planned to be phased over 20 weeks. Lisa was 10 weeks into the changeover. Things were going well, as Lisa explained. 'Our current concerns are centered around managing the changeover smoothly. Atlanta is a Greenfield site and most of our staff are relatively inexperienced, but we have put a lot of effort into training and we have managed so far without any real disaster, although it’s been a steep learning curve for all of us. We have been working totally in the dark. None of us had any experience of what it means to bring together the responsibilities of three different centres with different traditions, cultures and, to some extent, systems. I am just happy that we have managed well so far. We are currently operating at 75 per cent of our planned final volume and can already see how concentrating all activities on one site will allow us to achieve economies of scale compared to having separate country-based centres. We have invested in the latest telecommunications technology and call handling systems that allow us to route calls to 150 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual associates (call centres operators) with the appropriate technical and language skills. The larger scale also allows us to cope with the "natural" uncertainty in the volume and type of calls that come in. Around 40 per cent of our staff are bi-lingual and 5 per cent tri-lingual, which gives us the flexibility to cope with fluctuating demand between English, Spanish and French speaking customers. In fact, because all our customers are businesses, most of them can speak English, however we always try to use the appropriate language. It is a matter of courtesy and it also helps to build relationships with our customers'. The customer survey Prior to the changeover period, the New Jersey centre had carried out an extensive survey of its US customers. The summary results are shown in Figure 1. Lisa was pleased to have this data. 'The New Jersey centre’s survey provides us with a good benchmark. In the short term we have to make sure that we at least match this level of performance and in the long term we must improve on it. Certainly the overall level of satisfaction score is not good enough. Our challenge is to achieve excellence in all aspects of service. But customer service is not the only thing we have to monitor. It is vital that we get some financial payback for the investment in the new centre. I have been tasked with making this centre the ultimate in leading edge process management to ensure "world class" levels of efficiency. That is why we also intend to monitor productivity-based measures closely. In fact, since the new centre started we have been recording our progress closely on four key measures (Table 1 shows these measures for the first 10 weeks of the centre’s operation). These are the measures that we have decided will be the key performance indicators for the centre. "Calls per associate hour" is the best measure we have of our associates’ productivity and the "average call time" is a related measure that indicates how efficient the associates are at dealing with customer queries. As we get better at routing calls to the right associate quickly and efficiently and as our associates get to know the business better, the average call time should shrink to below eight minutes. "Average wait time" and the "percentage of abandoned calls" gives us an indication of how well we are matching our capacity to demand throughout the day. We have already started to experiment with using control charting procedures to monitor some of these performance measures, specifically, average call time, average wait time and the percentage of abandoned calls. It is by using this type of technique that we aim to develop one of the most efficient call centres of its type'. The future The progress of the call centre reorganisation in the customer service division was being watched closely by Kaston Pyral’s group management. The European reorganisation had gone reasonably well and the US centre seemed to be on track. Eddie Karowski, KPG’s CEO, was keeping a close watch on the new call centre strategy because he believed that customer service would become the way the company could differentiate itself. 151 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 1 Results of the customer survey carried out by the US call centre prior to the merger of the North American centres 'Our business is getting more competitive every year. We already have a range of products which are (we believe) the best in the world. Surveys show that the functionality and reliability of our equipment is outstanding compared to our competitors. But they are catching up fast. To stay ahead we need to do three things really well. First, we must be more innovative in the new products and services we introduce, especially now that new technology such as the control and diagnostics power of new software can be integrated into our systems. In effect we could offer "remote management" of customers’ systems, monitoring their equipment, automatically dispatching our engineers, providing customers with management reports, advising on their energy strategy and so on. The potential for exciting new offerings is vast. However, as yet, no one really knows what customers want in this area, I suspect they all want slightly different things from the hardware, control software and the services we offer, but whatever emerges we must be in a position to supply it. This will mean that we really need to understand customers’ actual requirements at a deep level. Then we must act fast to get those services to them. Second, whatever we finish up doing, we have to give impeccable service. Excellent customer service builds relationships and is the best way of establishing customer loyalty. Again, this means really understanding their needs. Third, we have to make sure that we are always in a position 152 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual to keep the customers updated with the new product and service offerings that could benefit them in order to make the best of sales opportunities. This is an ongoing education process. The better customers know what we can do, the more useful they will be in articulating their own needs and so stimulating our service development processes. Our call centre operations have the potential to help us in all of these areas. The question that we have to answer is how best to make sure that the three new consolidated call centres become the power house for keeping us ahead of the competition.'

The two specific issues are those of increasing internationalisation and (often along with that) increasing consolidation into larger units of capacity. The general issue is that of operations improvement. How should we improve? And how do we know if the improvement is appropriate and fast enough? The case contains both general statements of the company’s strategy along with a description of its decision to concentrate its call centre operations into three sites covering its global operations. Also, within the case is some quantified data both relating to the performance of the new North American centre and customer satisfaction with various aspects of service. Key questions A number of questions suggest themselves. • Does the company’s strategy of centralising on three call centres seem sensible? • How should the company judge its own improvement when implementing this strategy? • Does the company seem to be on track in the progress of its operations performance? Analysis In Chapter 6 of Slack and Lewis, an improvement cycle is suggested that includes the three stages – direct, develop and deploy. In other words, assess how the requirements of the market are directing the nature and direction of improvement, examine how the operation is developing appropriate capabilities in line with market requirements and assess how well the business is deploying its operations capabilities to enhance its potential market position. We can use these three headings to examine Kaston Pyral. Direct There are a number of aspects of this company’s market that are identified in the case, both from comments made by the company’s managers and from the customer survey carried out by the New Jersey call centre prior to its merger. • Decreasing telecommunications costs have enabled economies of scale to be realised by focusing on a small number of large call centres. • Technical support, such as that provided by the call centres, is becoming particularly important for KPG because of the complications arising from multiple ‘legacy’ control systems. 154 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Although not essential, the North American market appreciates the company’s ability to converse in the appropriate language (Spanish, English or French). • It is important to match and preferably improve on the level of performance achieved by the old New Jersey call centre. • Call centre productivity is seen as important in order to justify the investment in the call centres. • It is important to be more innovative both with new products and new services. This will place particular strain on technical support. • Exact customer needs are changing and not well understood. • Whatever customer requirements emerge, the company must be in a position to supply them. • Customer service is increasingly seen as important in building relationships and achieving customer loyalty. • Call centre operations are increasingly seen as being able to monitor the market and create sales opportunities. One could argue that the company is attempting to achieve everything at the same time. On one hand, the customer service vice president is keen to achieve both a smooth changeover to the new call centre system and high levels of productivity in order to justify the investment in the systems. On the other hand, the CEO stresses the need for innovation, service and using the call centres as a communication channel with customers. Of course, all companies are trying to achieve both reasonable levels of productivity and high levels of innovation, flexibility and customer service. Yet, here there is the sense that the relationship between productivity and service has not been fully explored. Certainly, promoting productivity-based improvement too far or too fast could seriously undermine the call centre’s ability to be useful as a driver of innovation and customer communication. The New Jersey survey is also interesting. The information it contains lends itself to being illustrated on an importance-performance matrix. Figure 1 shows the average scores for importance and performance for each of the seven aspects of customer service included in the survey. When survey data is averaged in this manner there will inevitably be some clustering of the results as is shown in Figure 1. However, there is sufficient discrimination between the points representing each aspect of service for some general conclusions to be drawn. • The overall level of satisfaction (averaging slightly over 4, where 1 is good and 9 is bad) seems to be higher than the individual average of the call centre’s performance in the nine aspects of service. This could be explained in a number of ways. For example, it could be that when asked to be more specific in their comments, customers tended to be more critical because they were more likely to recall specific negative service episodes. An alternative explanation is that those aspects of performance that rated higher than average (for example, ‘staff attitude’ and ‘knowledge of staff’) are valued significantly more than the other aspects of service. 155 © Nigel Slack and Michael Lewis 2012 GOOD Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual 1 2 PERFORMANCE 3 Staff attitude 4 Getting to right person 5 6 Knowledge of staff Time to resolution Staff understanding Completeness Kept informed 7 BAD 8 9 9 LOW 8 7 6 5 4 IMPORTANCE 3 2 1 HIGH Figure 1 Importance-performance matrix for the New Jersey survey • If we follow the zones of the importance-performance matrix as described in Chapter 6 of Slack and Lewis ‘staff attitude’ is in the ‘appropriate’ area, ‘knowledge of staff’ is on the border line between the ‘appropriate’ and the ‘improve’ zone. ‘Keeping the customer informed’ is just in the ‘urgent action’ zone, everything else is clearly in the ‘improve’ zone. Overall these are not the results from a delighted set of customers. • Generally, one would expect to see the aspects of service that customers rated highly in terms of importance being judged highly in terms of performance. In fact, if anything, this diagram shows that the more important the aspect of performance, the worse the company is seen as performing. • The two aspects of service judged to be performing the best are those associated with the skills and attributes of individual call centre staff. Many of those whose performance is less satisfactory are associated with the ability of the customer service division to integrate its own activities. This may provide a clue as to how improvement should be directed. Develop There is little mention in the case of how the call centres can be used to deliver high quality and innovative service while at the same time build a relationship with customers, which can be used both to stimulate ideas for new services and sell existing products and services. The ability to do these things will require the development of sophisticated capabilities both within the company’s human resources and in its technical ability to create integrated information systems. Yet, this is not referred to by the customer service vice president. What is seen as important is the rate of productivity improvement. This is contained in Chapter 6 of Slack and Lewis. According to this data, the company’s productivity is improving in a reasonably predictable manner. Figure 2 shows the Learning Curve for ‘associate hours per call’ as plotted by the 156 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual company. (‘Associate hours per call’ is the reciprocal of ‘calls per associate hour’. It is not known why the company chose to change their metric in this way). It shows that the company is likely to achieve its ambition of an average call time under 8 minutes. If current volume at approximately 64,500 calls per week is 75% of the final planned volume, then approximately 86,000 calls per week will eventually be reached. This means that within a year the call centre should have ‘experience’ of around 4,500,000 calls. Associate hours per call 10.0 1.0 0.1 0.01 1000 100000 100000 1000000 Cumulative volume of calls processed 10000000 Figure 2 Log-log experience curve for KPG Atlanta call centre The most important issue here is not that the data predicts ever-improving productivity; rather, it is that the company needs to ensure that productivity does not get in the way of all the other strategic objectives that the call centre will need to achieve. This type of operation is ideal for the application of statistical process control (SPC) techniques. Measures such as average call time, average wait time and percentage of abandoned calls are likely candidates to be monitored on an SPC basis. Remember what was stressed in Chapter 6 of Slack and Lewis though? The purpose of using control techniques is not only to detect when some process is moving out of control but also to enhance process knowledge. Therefore, SPC techniques will need to be integrated within an on-going experimentation programme designed to further understand the subtleties of the processes within the call centre. Deploy Deployment means that whatever capabilities have been developed within the operation are leveraged into the marketplace to enhance the competitive performance of the business. So, in order to assess how the company might think about its ability to deploy its capabilities, it is 157 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual useful to compare the capabilities it seems to developing with the broad position it seems to be aspiring to in its markets. Capabilities being developed – The company’s operations management seems to be understandably obsessed with the practical problems of merging the three North American sites into one integrated operation. In particular, it seems anxious to improve its productivity. Future market position – By contrast, the CEO, in his final statement, identifies the critical role of the call centre in establishing information links with existing customers and potential customers. The important capability he seems to be identifying as a vision for the future is the ability to gain a greater understanding of customers’ real needs as well as the ability to ‘educate’ customers to the potential of the company’s products and services. The obvious point to make here is the clear gap between what the operation is currently developing as its capabilities and what the CEO sees as its role in the future. 158 © Nigel Slack and Michael Lewis 2012 PROJECT ORLANDO AT DREDDO DAN’S ‘Most people see the snack market as dynamic and innovative, but actually it is surprisingly conservative. Most of what passes for product innovation is in fact tinkering with our marketing approach, things like special offers, promotion tie-ins and so on. We occasionally put new packs round our existing products and even more occasionally we introduce new flavors in existing product ranges. Rarely though does anyone in this industry introduce something radically different. That is why this project is both exciting and scary’. Monica Allen, the technical vice-president of PJT’s snack division, was commenting on a potential new product to be marketed under PJT’s best-known brand ‘Dreddo Dan’s Snacks’. The new product development project referred to was internally known as Project Orlando (no one could remember why). The project had been running officially for almost 3 years but had hitherto been seen as something of a long shot. Recent technical breakthroughs by the project team now made the project look far more promising and it had been given priority development status by the company’s board. Even so, it was not expected to come to the market for another 2 years. ‘Orlando’ was a range of snack foods which had been described within the company as ‘savory potato cookies’. Essentially they were one a half-inch discs of crisp, fried potato with a soft dairy cheese-like filling. The idea of incorporating dairy fillings in snack had been discussed within the industry for some time but the problems of manufacturing such a product were formidable. Keeping the product crisp on the outside yet soft in the middle, while at the same time ensuring microbiological safety, would not be easy. Moreover such a product would have to be capable of being stored at ambient temperatures, maintain its physical robustness and have a shelf life of at least 3 months. Enough of the technical problems associated with these requirements had been solved by the Project Orlando team for the company to have real confidence that a marketable product would eventually emerge. It would however be the most important new product development in the company’s history. ‘The main problem with this type of product is that it will be expensive to develop and yet, once our competitors realise what we are doing, they will come in fast to try and out-innovate us. Whatever else we do we must ensure that there is sufficient flexibility in the project to allow us to respond quickly when competitors follow us into the market with their own ‘me-too’ products. We are not racing against the clock to get this to market, but once we do make a decision to launch we will have to move fast and hit the launch date reliably. Perhaps most important, we must ensure that the product is 200 per cent safe. We have no experience in dealing with the microbiological testing which dairy-based food manufacture requires. Other divisions of PJT do have this experience and I guess we will be relying heavily on them’. (Monica Allen) Monica, who had been tasked with managing the now much expanded, development process, had already drawn up a list of key decisions she would have to take. • How to resource the development project – The division had a small development staff, some of whom had been working on Project Orlando, but a project of this size would require extra staff amounting to about twice the current number of people dedicated to product development. • Whether to invest in a pilot plant – The process technology required for the new project would be unlike any of the division’s current technology. Similar technology was used by 159 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual some companies in the frozen food industry and one option would be to carry out trials at these (non-competitor) companies’ sites. Alternatively, the Orlando team could build their own pilot plant, which would enable them to experiment in-house. In addition to the significant expense involved, this would raise the problem of whether any process innovations would work when scaled-up to full size. However, it would be far more convenient for the project team and allow them to ‘make their mistakes’ in private. • How much development to outsource – Because of the size of the project, Monica had considered outsourcing some of the development activities. Other divisions within the company may be able to undertake some of the development work and there were also specialist consultancies that operated in the food processing industries. The division had never used any of these consultancies before but other divisions had occasionally done so. • How to organise the development – Currently the small development function had been organised around loose functional specialisms. Monica wondered whether this project warranted the creation of a separate department independent of the current structure. This might signal the importance of this project to the whole division. The budget to develop Project Orlando through to launch had been set at $30m. This made provision to increase the size of the existing development team by 70% over a 20-month period (for launch 2 years from now). It also included enough funding to build a pilot plant which would allow the team the flexibility to develop responses to potential competitor reaction after the launch. So, of the $30m around $12m was for extra staff and contracted-out product development, $5m for the pilot plant and $3m for one-off costs (such as the purchase of test equipment, etc.). Monica was unsure whether the budget would be big enough. ‘I know everyone in my position wants more money, but it is important not to under fund a project like this. Increasing our development staff by 70% is not really enough. In my opinion we need an increase of at least 90% to make sure that we can launch when we want. This would need another $5m spread over the next 20 months. We could get this by not building the pilot plant I suppose, but I am reluctant to give that up. It would mean begging for test capacity on other companies’ plants, which is never satisfactory from a knowledge-building viewpoint. Also it would compromise security. Knowledge of what we were doing could easily leak to competitors. Alternatively we could subcontract more of the research which may be less expensive, especially in the long run, but I doubt if it would save the full $5m we need. More importantly, I am not sure that we should subcontract anything which would compromise safety, and increasing the amount of work we send out may do that. No, it’s got to be the extra cash or the project could overrun. The profit projections for the Orlando products looks great (see Exhibit 1) but delay or our inability to respond to competitor pressures would depress those figures significantly. Our competitors could get into the market only a little after us. Word has it that Marketing’s calculations indicate a delay of only 6 months could not only delay the profit stream by the 6 months but also cut it by up to 30%’.

First, that there was a coherent and well thought-out strategy for the development of Project Orlando over the next 2 years. Second, that saving $5m on the development budget would be a false economy. 161 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – PROJECT ORLANDO AT DREDDO DAN’S This case exercise covers many issues found in new product and service development projects. In particular the case examines a new type of product which is to be launched in an uncertain and unpredictable market and also carries some development risks. Above all the project is a significant development for the company with both the potential for major competitive benefits and some downside risk. Key questions In effect the questions have been defined by Monica Allen in her analysis of the project. She sees the key decisions as follows. • How to resource the project. In other words, how many people to devote to developing the new product. • Whether to invest in a pilot plant or, alternatively, experiment with another company’s process technology. • How much of the total development effort to outsource. • How to organise the resources which will be devoted to developing the new project. Analysis The first point to emphasise is that this is a very significant project for the company. In terms of the dimensions discussed in Chapter 7 of Slack and Lewis, the new product could be classed as a ‘development of an existing product/service’, but represents a greater degree of process change, probably somewhere between a ‘development to existing processes’ and a ‘pioneer process’. As Chapter 7 in Slack and Lewis implies, such a project is difficult to manage because there are so many things going on at the same time. Not only is the product technology (recipe and composition) novel to the company it is being launched into a market for whom the product will be totally new. Furthermore, the process, although similar to processes used elsewhere, is totally novel for the company. This means that learning and knowledge acquisition within the development project will be particularly difficult. Yet learning is likely to be an important issue for the company. Competitors (they assume) will respond quickly when Dreddo Dan’s product hits the market. They must be in a position to counterattack. This will require a considerable degree of confidence with the product and process technologies. The knowledge acquired during the development process is the foundation for this confidence. Market-based performance objectives As far as the market into which this new product will be launched is concerned a number of performance objectives are mentioned in the case. Perhaps the most important are as follows. 162 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Safety – project Orlando involves dairy products, a material with which the company is not familiar and which poses considerable microbiological risk. Not only do the company have a moral obligation to ensure product safety, any health-related issues close to product launch would be a marketing disaster. • Quality – the quality of the products must be absolutely on-specification from day 1 of their launch. This is a novel product and customers are likely to form their judgement of it on their first tasting. If the first packet they buy is not up to standard, they probably won’t buy a second one. • Flexibility – there are several areas of uncertainty within this development project. There is uncertainty around the timing of the launch. There is uncertainty as to exactly what the final form of the launch range of products will take. Above all, there is uncertainty as to how competitors will respond in the short and medium term. All these uncertainties will mean that both volumes of production and the variety of products produced will not become clear until later on in the development process. The development process must be sufficiently flexible to cope with this. • Cost – this is never unimportant. What is uncertain is how much of an issue it is for the company. Whereas they would not wish to see cost escalate out of control, the case implies that issues of safety, quality and flexibility are more important than development cost. Development operations resources The four questions posed by Monica Allen in fact match the four decision areas which have been stressed throughout Slack and Lewis and which were also proposed as an approach to examining development resources. • Capacity – generally this means the size, composition and location of any development team. In this particular case there is no stated location issue so capacity, in effect, means the number and capabilities of the development team devoted to the project. • Supply network – the issue here is one of how much of the development effort to keep inhouse and how much (if any) to outsource. Other parts of the group have some experience in some aspects of this new technology and also have used outside consultancies. Should Monica use any of these outside resources or try and keep everything in-house? • Process technology – although by ‘process technology’ in this context we are usually referring to any technology (such as computer-aided design, CAD), which is used in the development process itself, we can include the decisions over the pilot plant in this category. This is because the pilot plant will be used to build knowledge around the nature of the product itself. • Development and organisation – the main issue here is how to organise the development process. Will the existing functional organisation be sufficient? Or should a dedicated team be formed? 163 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Using an operations strategy matrix One method of exploring these questions is to use the operations strategy matrix as suggested in Chapter 12 of Slack and Lewis. Figure 1 illustrates briefly what such a matrix might look like. Performance Objectives Safety No significant relationship. Is the company willing to subcontract any responsibility for safety? Pilot plant may enable potential hazard to be detected. Dedicated team may help reinforce safety objective. No significant relationship. Strict quality standards need to be communicated to any subcontractor. Pilot plant may enable better quality learning. Dedicated team may help to reinforce quality objective. Need to have sufficient development capacity to respond quickly to accelerated development needs. Very significant, the larger the development team the higher the cost of development. Does subcontractor development imply reduced flexibility? Pilot plant would be dedicated so increase flexibility, but may have scale-up problems. Dedicated team likely to be more flexible if all necessary skills are represented in it. Subcontracting development to specialists may reduce total development cost. Pilot plant is likely to be Dedicated team likely to be more expensive, more expensive that using partners’ capacity. functional organisation usually gives higher utilisation of staff. ** * Quality ** * Flexibility ** * Cost * Capacity Supply Network Size of team? Subcontract any development? Process Technology Development and organisation Build pilot plant? Dedicated team? Market Competitiveness Resource Usage Decision areas Figure 1 Operations strategy matrix for Project Orlando Note that the analysis highlights the trade-off between safety, quality and flexibility objectives on one hand and the cost objective on the other. Broadly, a development strategy which includes putting together a relatively large and dedicated development team who subcontract relatively little of the work, except where it offers distinct technical advantages, and who build their own pilot plant so as to promote their own product and process learning, is likely to promote safety, quality and flexibility. However, all these decisions are expensive. Therefore, the decision comes down to how much the company are prepared to invest in the development in order to achieve its other development objectives. The case seems to indicate that safety, quality and flexibility are much more important than development cost. Therefore, the company may wish to consider the following advice. • Make sure that the development team is large enough to encompass the relevant skills and has sufficient capacity to respond to changing or emerging development needs. • Some of the development can be subcontracted, but only when there are distinct technical advantages in doing so. It is important that the development team build up their knowledge in terms of both the product and the process. This is more difficult when much of the development is subcontracted. Where any development is subcontracted, consider identifying a dedicated member of the development team to work with the external experts. 164 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • A pilot plant could have significant advantages providing there is reasonable confidence that scale-up problems will not be too great. A dedicated pilot plant would, again, enhance learning opportunities and would enable changes in development direction to be accommodated quickly. It may even be worthwhile considering both building a pilot plant and using spare capacity on other companies’ full-scale processes. This may reduce the scale-up risks associated with using the pilot plant. • For a project of such importance a dedicate team is likely to be superior to using the existing, largely functional (by specialism) structure. However, it is important to ensure that the team maintain contacts with their specialist colleagues in order to be able to deploy the whole company’s knowledge as and when required. 165 © Nigel Slack and Michael Lewis 2012 THE FOCUSED BANK It is only 3 years since e1TM bank was first formed as a joint venture between 6th State Bank of Victoria and AuroraTM, a leading provider of outsourcing services to the financial sector based in New York. The strategic intent was to become an early-entrant into the exclusively on-line retail banking firm operating throughout North America. Although not expected to register any real profit for 5 years, the banks tightly defined operational and market proposition, ensured that all customers contributed to an ongoing operating profit. In its first year the new bank only signed up 25,000 customers. However, as household Internet usage continued to grow rapidly, aggressive price-related marketing (lower loan and higher savings interest rates) and a developing reputation for dependability (a form of early-mover advantage) meant that after 30 months the bank had passed the 0.5 million customer mark. During the 1990s a range of new entrants (savings and loans, supermarkets, insurance providers, etc.) had made the retail banking sector increasingly competitive. Despite these pressures, the industry continued to generate significant profits and remain highly attractive to shareholders. For instance, in the first six months of 1997 (the year that e1TM was launched) the overall sector index rose by almost 50%. At the time, most of the established 'high street' banks were talking a great deal about the potential impact of the Internet on their core service delivery (see the table detailing average cost per transaction) but most were still a long way from launching a fully online option. TRANSACTION TYPE Branch Telephone ATM PC Banking Internet COST ($) 0.91 0.49 0.25 0.01 0.009 Despite this initial success, the last 6 months have seen their rate of customer growth begin to flatten off. As increasing numbers of customers can access internet-based services, more and more competitors have entered the market including, perhaps most significantly, the long established high street banks. Having established a strong presence in the retail market by exploiting core operational strengths, the firm began to consider how they could build new markets and as a result e1’s CEO, Kevin Tilly, hired James Phillips from an international consulting firm to head up a new product development process. After an in-depth market analysis, the decision was taken to explore the potential of the corporate services market. As James explains, there were very good reasons for choosing this particular segment. 'Like our attack on retail banking, this is a market with largely the same well-established players who quite frankly charge a lot of money and provide very ordinary service. The tragic thing is that our analyses suggested that the big players didn’t make anywhere near the money they could out of these customers simply because they were so inefficient. This meant that our core strengths could be leveraged effectively. Several of the key corporate clients banked with us as individuals and in focus groups expressed surprise that we didn’t offer our services to different customer groups.' Starting with a small pilot service (3 clients) the firm began, in early 1999, to offer corporate services. They hired a team of 8 corporate banking specialists from one of the established players and invested substantial time and energy in defining and meeting the needs of these new ‘premium’ clients. After 6 months they had added 15 new clients, 7 new staff and were establishing a new reputation in the marketplace. James Phillips recognised, however, that they 166 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual needed to add several new services, hire more staff and open a dedicated New York office if they were to truly realise their potential. A special meeting was convened to discuss the project and seek approval for further expansion investment. It did not proceed quite as James had expected, as the following excerpts illustrate. 'As you know, these clients are paying a lot of money for the services we offer. They came to us because of our high-tech reputation but they will only stay if we build strong relationships. This means more staff and better facilities. Similarly, some of them are hinting that we don’t offer the full range of products. This is not a problem yet and as I have explained to them, with our expertise I see no reason why they shouldn’t get exactly what they want. They were very impressed by this kind of commitment.' James Phillips, New Product Director 'You all know we needed to grow rapidly in order to be viable in the medium-term! When we first started our unique proposition was enough to win us new customers but the big players are no longer as hopeless as they once were! I see this experiment as an unambiguous success and fully support James request for further investment' Maria Andorri, Marketing Director 'I think that no-one disputes the growth argument, the question is how do we achieve it? We founded the business on a simple proposition and I think that we’re in danger of destroying that with this new venture. What James seems to be saying is that they like what we do but can we change it all!' Berny Kovak, Operations Director '….you’ve all seen the numbers, you know that basic account opening rates of growth are slowing, I thought that this was what I had been hired to do, quite frankly I can’t see why this is even an issue!' James Phillips, New Product Director Neither Berny nor James was willing to compromise on their positions. As a result the meeting became somewhat acrimonious and Kevin Tilly proposed a short analysis of the overall viability and impact of the new venture. 167 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – THE FOCUSED BANK This example describes the process of operations strategy (formulation and implementation) with the primary focus on achieving fit: the firm faces different market segments, changing competitive circumstances, functional disagreements, differing levels of expertise, short- and long-term concerns, etc. It also, inevitably, addresses sustainability and risk and equally comprises more specific issues relating to service design and technological infrastructure. Analysis The Focused Bank was formed as a joint venture between an established financial services business and a provider of infrastructure support to this industry segment. Therefore, although the business idea sought (first-mover advantage) to become the first exclusively on-line retail banking firm, it was far from being an independent start-up. The operation proved to be very successful and after only 30 months had signed up over 1 million customers to its new service. Despite this initial success, more recently (as competitors saw the potential and launched on-line banking as a complement to their core delivery channels) they have experienced a declining rate of customer growth. As a result, the firm began to consider how they could build new markets and hired a new product development manager. After an in-depth market analysis, the decision was taken to explore the potential of the corporate services market. The firm hired a team of 8 corporate banking specialists to serve 3 ‘pilot’ clients. After 6 months they had added 15 new clients, 7 new staff and were establishing a new reputation in the marketplace. Now they have reached a crucial decision point, should they continue to expand the corporate service business or re-focus on their original market. Advantages of the Corporate Service Offering The NPD and marketing directors have identified a number of key advantages associated with the new service offering. In particular, given the slow down in their core market, this mediumterm strategy offers a point of entry into a market with apparently favourable market conditions (well-established players providing 'ordinary service') akin to their retail launch. In addition, an efficient service provider (like focus) could realise significant margins on this ‘premium’ service and it would allow then to build upon their established reputation (key corporate clients banked with Focus as individuals). Disadvantages of the Corporate Service Offering The Operations director has some concerns with the shift into corporate services. He believes that sometimes 'strategic managers' place too much emphasis on the market environment, without considering what the firm is capable of actually delivering. Focus Bank may have clarity about its market positioning but this also has significant internal strategic implications. The additional complexity (high variety, low volumes, high visibility, etc.) of the new services is predicted to have a significant impact on the processing capabilities of the firm. In particular, the Operations director is concerned that this will affect the focus that he has achieved in his back office. 168 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What is the Question? This case is illustrative of a number of different operations strategy issues. Regardless of this breadth however, the key question remains, 'Should The Focused Bank take the next step in developing their corporate business and make a major investment?' Options/Discussion Criteria Unlike previous cases, the suggestion for this example is to structure analysis not around three different options. This case provides a basis for assessing the three different elements, as defined in Chapter 8, which constitute an operations strategy that 'fits': 1. Exploring what it means for an operations strategy to be comprehensive 2. Ensuring there is internal coherence between the different decision areas and that they correspond to the true priority attached to each performance objective and 3. Highlighting which resource/requirement intersections are the most critical with respect to the broader financial and competitive priorities of the organisation. On reaching this point, any debrief can include generating and discussing ‘what to do next’ options. Evaluation Before addressing the specific nature of the strategy process, it is instructive to articulate a more conceptual picture of operations strategy fit. It is helpful to develop a generic map of the firms’ resource and requirement position. X1 specific market criteria A Y1 Y2 B tight fit X2 ideal level of resource capability The precise location of Focused Bank on such a map is, of course, somewhat arbitrary but two themes can provoke interesting debate. The success of the firm in both its chosen markets appears to suggest that it has achieved a strong degree of fit. Given the first-mover nature of the initial offering, in many ways the service launched at position A (i.e. above ‘normal’ levels of (y1) market requirements and (x1) operational capability). On the other hand, with the new corporate service, even the managerial advocates of the new offering argue that in some ways it falls short of delivering the complete performance that the market requires (y2) because it lacks the appropriate level of operational capability (x2). Practically, given the dynamic nature of markets and capabilities, all operations find themselves in this position at one time or another. The Focused Bank, therefore, has to explore the performance envelopes (defining the minimum 169 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual degree of fit necessary to ensure competitive survival) associated with each of its two service offerings. Comprehensive This case can be used to discuss the practical value of a range of different operations strategy models (including the book’s OS matrix). At the very least these models provide an aidememoire for determining the ‘comprehensiveness’ of an operations strategy. Many operations have simply failed in their strategies to notice the potential impact of, for instance, new process technology. Similarly, many attempts to achieve fit have failed because operations have paid undue attention to one of the key decision areas – often the softer, people-related aspects. In debriefing the case, the OS matrix can be used to flesh out (infer) the underlying capabilities that the firm must have had in place to successfully serve first the mass retail and then the corporate markets. For instance, operational factors that were central to the start-up like the reliable, scalable front and back-office technology (rapid volume growth), factors influencing capacity, costs associated with customer contact (initially limited to a simple back up email and telephone call-centre), etc. might be less relevant for the new service offering. Coherence At the same time as capturing as many of the critical variables as possible, it is also important to constantly reflect upon the overall coherence of the decision elements. The focused bank operation needs to achieve a correspondence between the choices made against each of the decision areas and the relative priority (internally and externally) attached to each of the performance objectives. There are a number of ways of judging the relative coherence of the operations strategy (in a similar vein to the analyses of Dresding Medical, Hagen Style, Bonkers Chocolate, etc.). Below is a simple polar representation (again very powerful in class debrief) of the original and new service offerings, derived (again) from the generic performance objectives (quality, speed, dependability, flexibility and cost). high-speed transactions high-speed transactions 24-hour service availability low-cost processing 24-hour service availability low-cost processing high-contact customer service product/service flexibility high-contact customer service 1 2 3 4 5 product/service flexibility high dependability transactions high dependability transactions Figure: Core retail and New corporate service profiles 170 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Criticality In addition to the difficulties of ensuring coherence between decision areas, there is also a need to include financial and competitive priorities. Although all decisions are important and a comprehensive perspective should be maintained, in practical terms some resource/requirement intersections will be more critical than others. The Hill framework (in Chapter 8) highlights some of these issues by stressing relative customer priorities (order-winners/qualifiers: see Chapter 2) but it does not pay sufficient attention to other effects on criticality – in particular, the influence of competitor behaviour. Here again the OS matrix can be used to develop a discussion of the critical intersections and related options facing the firm. For instance: COST QUALITY KE SPEED FLEXIBILITY develop & organise supply network process technology capacity KE 1. If the chosen option is to commit fully to the corporate venture then a critical or key intersection becomes that option as between ‘quality’ and ‘development and organisation’. In other words, as the NPD director explains in the case: 'these clients are paying a lot of money for the services we offer. They came to us because of our high-tech reputation but they will only stay if we build strong relationships. This means more staff and better facilities'. 2. Conversely, the success of the original retail service was directly tied to the ability of the underlying process technology (customer-facing and back-office) to provide volume flexibility – in the face of surprisingly rapid volume growth. This cost-effective flexibility may offer little value in the new markets, where variety flexibility will rapidly predominate: 'some of [the new corporate clients] are hinting that we don’t offer the full range of products. This is not a problem yet and as I have explained to them, with our expertise I see no reason why they shouldn’t get exactly what they want. They were very impressed by this kind of commitment.' 171 © Nigel Slack and Michael Lewis 2012 CLEVER CONSULTING The Clever Consulting Company (CCC) was first established in October 2000 when four business school finance faculty decided to ‘…try and do it for real … and also make a lot more money!’. The firm was not entirely independent. The idea was created with the support of their university’s business development scheme, whereby for an equity stake and some supervisory influence, the university provided the opportunity, continued association with the university name and some basic facilities. The original operation comprised the four partners, four consultants (all recent MBA graduates who had been taught by the academics), three analysts (recent first degree graduates from the university) and one person providing administrative and secretarial support. At the start of the venture, none of the partners were firmly established as the leader, they were all first among equals. ‘During the first 18 months everything went incredibly smoothly… the initial proposition was to leverage our academic credibility and functional expertise in order to give us a niche position and the market responded. We began with one big bank as a client but very quickly we undertook two or three smallish projects for other clients who without exception came back to us with larger and longer projects. No-one minded putting in the hours… which frankly were often crazy… I guess that in those early days commitment and creativity drove growth’ – Managing Partner. By the end of the second full year of trading, however, it became clear that the firm’s flat managerial structure was unsustainable, especially in their dealings with the university parent and other equity holders. Although the firm continued to grow organically, November 2002 saw the firm enter into a prolonged period of leadership crisis. Eventually one of the partners was firmly established as the Managing Partner but it was not a smooth transition. For nearly a year there was personal and professional conflict within the firm making it difficult for the firm to address strategic growth and corresponding structural issues. Evidence for the impact of this crisis on CCC’s business can be seen in the annual revenue figures. The years immediately before the crisis saw growth of 55 and 66 per cent, whereas during this difficult period growth fell to 17 per cent. Whilst apparently respectable, this was considerably lesser than their growth target and at the same time a number of operational initiatives floundered. Recruitment, training and promotions became difficult and plans to develop a web-based infrastructure for capturing project knowledge were postponed indefinitely. The crisis of leadership was only partially resolved when, in April 1997, two of the founding partners returned to full-time academia in different institutions. A year later the third founding partner retired. During the last two financial years, CCC’s revenues have grown by an impressive 93 and 113 per cent, arguably a demonstration of the benefits of clear managerial direction. Unfortunately, this level of growth has simply served to reinforce many of the structural and infrastructural challenges ignored over the last 2 years. What kind of consulting operation was CCC and what kind did it want to become? It seemed clear that depending on the type of work the firm undertook/received, different structures would be needed – with a range of operational implications. For instance, the more procedural or routine consulting work becomes higher than the analyst/partner ratio. Consequently, intense competition for career progression up to partner level is created and staff turnover in this type of firm is very high. If staff turnover is high then preventing valuable knowledge from leaking out of the firm becomes critical. Similarly, too complicated a mix of different types of assignments can make capacity planning extremely 172 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual complex etc. Whilst the Managing Partner had very clear views on the nature of the dilemma they faced, she was less certain about the strategy they should follow. ‘I love this business and believe that we have created something special here. I want to build a firm that will still be here in 10 years time but I know that in order to develop truly sustainable competitive advantage we have to get over a number of obstacles… Operationally we need to decide what kind of consulting firm we are going to be. I read a book recently1 that summed it up very effectively. There is the kind of consulting work that comprises a large ‘grey matter’ quotient; the work with a large ‘grey hair’ quotient; and work where the problem is recognised, well understood and just needs ‘bright’ people resource thrown at it. I believe that we began life as a combination of the first two but over time… and with our senior people problems… I have tried to steer us towards the first rather than second mode of operation. The future might be different again?’ 1 Maister, D. (1993) Managing the Professional Service Firm. New York: Free Press. 173 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – CLEVER CONSULTING The nature of this professional service example – without large-scale investment decisions (capacity, process technology, supply network etc.) – allows us to focus directly on the ‘process of operations strategy’. In addition to generic discussion of the reconciliation of resources and requirements, the exemplar also provides some details on specific themes such as indirect process technology (knowledge management system) and different types of management consultancy process. Analysis The dilemmas faced by Clever Consulting Company (CCC) are in many ways typical of a small business start-up. Amongst its founders there was an initial passion ‘to do something different’, allied with a desire ‘to make some serious money’. The initial ownership and financing arrangements were complex and perhaps best characterised as opportunistic rather than strategic. The key events in the firms’ development can be summarised as follows: • The firm began operating with four partners, four consultants (MBAs), three analysts (recent graduates) and one person providing administrative and secretarial support. The small size of the operation meant that management structures and formal decision-making procedures were underdeveloped (not needed?) Their niche market proposition sought to leverage a deep repository of academic credibility and functional expertise – beginning with a single large client (retail bank) who had guaranteed them a certain amount of business. • The first 18 months saw the addition of three pilot projects for new clients that transformed into larger and longer projects. There was no expansion in capacity but more and more utilisation of the existing resource base. • By the end of the second full year of trading (after annual revenue growth of 55 and 66 per cent, respectively), the limitations of the original managerial and financial structures became increasingly apparent. In particular, the founding partners began to disagree about the future direction of the business and for nearly 12 months there was personal and professional conflict making it difficult to address either market or resource issues. Annual revenue growth during this period growth fell to 17 per cent. At the same time, a number of operational initiatives floundered. Both recruitment (capacity) and training/promotion (development and organisation) became difficult, and plans for systemic project knowledge capture (indirect process technology) were postponed indefinitely. • Eventually two of the founding partners returned to academia and, 12 months later, a third founding partner retired. This left the fourth founder clearly established as the Managing Partner but facing a number of strategic dilemmas. In particular, she had lost 75 per cent of the ‘grey matter’ that had underpinned their original market proposition. Despite these challenges, these 2 years saw CCC’s revenues grow by 93 and 113 per cent, arguably a demonstration of the benefits of clear managerial direction. Unfortunately, this level of growth also reinforced many of the structural and infrastructural challenges. 174 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Partners (P ) Consultants (C) Analysts (A) Partners (P ) Consultants (C) Analysts (A) Partners (P ) Consultants (C) Analysts (A) Grey Matter Assi gnments: This type of work is typically unique and requires a considerable amount of innovative and creative input. There is a low ratio of analysts to partners. Grey Hair Assignments: This type of work is similar to previous assignments, therefore the firm can apply/trade-on experience. There is a larger ratio of analysts to partners. Procedure Assignments: This type of work usually involves well-recognized and familiar problems. The solution (method) is often highly standardized. There is a high ratio of analysts to partners. As discussed in Chapter 8, the OS matrix could be used to illustrate how different resource and requirement issues have become more or less important over time in the CCC case. It also allows us to discuss the complexity, coherence and comprehensiveness of the overall strategy. (n.b. this might be a good mechanism for introducing any case discussion). However, it does not capture the balancing act of reconciliation over time. The figure below is an attempt to represent this dynamic process. Level of market requirements ? y5 D y4 C y3 y2 B y1 A x1 Level of operational resource capability x4 x2 x5 x3 From the outset (point A) CCC deployed a high degree of (applied) academic experience and knowledge into the marketplace for a single client. Therefore, the initial level of market requirement (shown as level y1) was less than the operations’ capability to deliver (x1). The 18month ‘start-up’ phase is represented on the above figure by the transition to point B. Having satisfied their first client, trading to a certain extent off the reputation of the university parent, the firm won more work (→y2). Over this period, they leveraged and refined their capabilities over a number of months (→x2). After this ‘honeymoon period’ however, the managerial and structural difficulties begin to emerge. This is why the transition from point B to C is shown as a shift to the left of the ‘line of fit’ – indicating that internal problems were leaving them with insufficient capability to meet market requirements (failing to meet growth targets, insufficient 175 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual infrastructure development etc.) After resolving the leadership issue, the firm began once again to win more and more public and private work and over time (y3→y4) reinforced underlying capabilities (x3→x4). The dilemma that the Managing Partner faces however is to try and maintain this fit. She is uncertain both about the nature of the market to pursue (and the corresponding dynamics of the selected segment) and the type of operational structures needed to support this ambition (x5, y5). What is the question? As mentioned earlier, this case is illustrative of the challenge of achieving sustainable fit. By corollary therefore, the material can also be used to discuss issues of static fit and extended into consideration of risks. Regardless of how much breadth is given to debrief. However, the key question is some variant of, ‘What kind of consulting operation was CCC, and what kind did it want to become?’ What are the options? In developing an overall strategy for the consulting operation, any number of specific resource or market-focused initiatives might be identified. The Managing Partner however, had recognised that the categorisation proposed in the Maister (1993) book, Managing the Professional Service Firm (Free Press, New York) suggested three ‘broad-brush’ visions, which highlighted the key dilemmas faced by the firm. Types of consulting operation Depending on the type of work a consultancy firm undertakes/receives, different operational structures and arrangements are needed. For instance, the more procedural or routine consulting work becomes the higher the analyst/partner ratio. Consequently, intense competition for career progression up to partner level is created and staff turnover in this type of firm is very high. If staff turnover is high then preventing valuable knowledge from leaking out of the firm becomes critical. Similarly, too complicated a mix of different types of assignments can make capacity planning extremely complex etc. The Maister typology can be summarised as follows: Quoting the Managing Partner: ‘…we need to decide what kind of consulting firm we are going to be. There is the kind of consulting work that comprises a large ‘grey matter’ quotient; the work with a large ‘grey hair’ quotient; and work where the problem is recognised, well understood and just needs ‘bright’ people resource thrown at it. I believe that we began life as a combination of the first two but over time… and with our senior people problems… I have tried to steer us towards the first rather than second mode of operation. The future might be different again?’ Option A – Refocus the business on its origins, seeking to reinforce the reputation for originality and creativity. Option B – Build on current strengths, with some experienced consultants and a definite market orientation and continue to look for relatively challenging, but not innovative problems. 176 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Option C – Expand the business, hire more consultants and seek to develop procedural solution methods for a range of problem sets. Alternative discussion criteria Although this teaching note follows the standard ‘questions and options’ structure, the analysis of this case could also be structured around the three process elements discussed in Chapter 14. These themes (organisational learning, appropriation of competitive benefits and the impact of path dependency) are offered as ‘shorthand’ for evaluating the degree to which an operations strategy might achieve ‘sustainable’ fit. In other words, the case can be used together with The Focused Bank (Chapter 13) and Saunders Industrial Services (Chapter 15) as a set for considering the process of operations strategy. Evaluation It is possible to apply many of the models and frameworks described throughout the book and more specifically in the process chapters (13, 14 and 15) to this case. In particular, however, the case provides a useful way of illustrating application of the frameworks for classifying (1) static barriers to entry and imitation and (2) dynamic mechanisms for innovation and change. In discussing the different options, the following issues could be raised. Option A – Discussion of this option can highlight some interesting trade-offs between static resource-based sustainability mechanisms. For instance, emphasising individual senior consultants and ‘grey matter’ type assignments can lead to experience, knowledge and reputation that are very difficult to copy. At the same time, such individuals are highly mobile and can easily (as shown in the CCC example) move, effectively diminishing the firm’s competitive advantage. Such a strategy also embodies the benefits and disadvantages of ‘double-loop learning’. It can be creative, flexible and responsive to dynamic market requirements, but can also lead (as during the yearlong leadership crisis) to paralysis and confusion. Option B – This represents the option with the most continuity with the preceding 2/3 years. It will be managerially attractive because it exploits the benefits of incremental capability development. Particular discussion can be generated around an application of the internal ‘barriers to imitation’ dimensions to a professional service. At the same time, some discussion of the ‘innovators dilemma’ (p. 491) should also highlight some of the dangers. Option C –The third option is in many ways the most attractive from a growth perspective. It involves dealing with more and more clients and hiring relatively low cost analysts who deploy standardised methodologies. However, in the discussion of sustainability in the face of competition, biological analogies were drawn with the zero-sum games of a species fit with its environment. In other words, it never gets any easier. Moreover, the strategy that appears to be the most attractive can quickly become the one that rivals will also adopt, learn to block. Moreover, as CCC developed in this direction, their procedural innovations could soon be countered by others that are bigger (and can compete on price) and better established in this market. With some additional material (i.e. management consultancy market data), it is possible to apply the external ‘barriers to entry’ models. 177 © Nigel Slack and Michael Lewis 2012 SAUNDERS INDUSTRIAL SERVICES Saunders Industrial Services (SIS) began life as the classic family firm. Art Saunders’ father had opened a small manufacturing and fabrication business in his hometown of Milwaukee on returning from duty in World War II. He had successfully leveraged his skills and passion for craftsmanship over many years whilst serving a variety of different industrial and agricultural customers. Art himself spent nearly 10 years working as a production engineer for an automotive original equipment manufacturer (OEM) but eventually returned to Milwaukee to take-over the family firm. Exploiting his experience in mass manufacturing, Art spent more than 20 years building the firm into a larger scale industrial component manufacturer but retained his father’s commitment to quality and customer service. In 1985 he sold the firm to an UK-owned industrial conglomerate and 10 years later in 1995 it had doubled in size again and now employed approximately 600 people and had a turnover approaching $210 million. Throughout this ‘third’ period the firm had continued to target their products into niche industrial markets where their emphasis upon product quality and dependability meant they were less vulnerable to price and cost pressures. However, in 1992, in the midst of difficult economic times and widespread industrial restructuring, they had been encouraged to bid for higher volume and lower margin work. This process was not very successful but eventually culminated in a 1994 tender for the design and production of a core metallic element of a child’s toy. Interestingly, the client's firm, KidCorp, was also a major customer for other businesses owned by SIS’ corporate parent. They were adopting a preferred supplier policy and intended to have only one or two purchase points for specific elements in their global toy business. They had a high degree of trust in the parent organisation and on visiting the SIS site were impressed by the firm’s depth of experience and commitment to quality. In 1995, they selected SIS to complete the design and begin trial production. 'Some of us were really excited by the prospect … but you have to be a little worried when volumes are much greater than anything you’ve done before. I guess the risk seemed okay because in the basic process steps, in the type of product if you like, we were making something that felt very similar to what we’d been doing for many years.' Operations Manager 'Well, obviously we didn’t know anything about the toy market but then again we didn’t really know all that much about the auto industry or the defence sector or any of our traditional customers before we started serving them. Our key competitive advantage, our capabilities, call it what you will, they are all about keeping the customer happy, about meeting and sometimes exceeding specification.' Marketing Director The designers had received an outline product specification from KidCorp during the bid process and some further technical details afterwards. Upon receipt of this final brief, a team of engineers and managers confirmed that the product could and would be manufactured using an up-scaled version of current production processes. The key operational challenge appeared to be accessing sufficient (but not too much) capacity. Fortunately, for a variety of reasons, the Parent Company was very supportive of the project and promised to underwrite any sensible capital expenditure plans. Although this opinion of the nature of the production challenge was widely accepted throughout the firm (and shared by KidCorp and Parent) it was left to one specific senior engineer to actually sign both the final bid and technical completion documentation. By early 1996, the firm had begun a trial period of full volume production. Unfortunately, in this design validation process SIS had effectively sanctioned a production method that would prove 178 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual to be entirely inappropriate for the toy market but it was not until mid-1997 (16 months later) that any indication of problems began to emerge. Throughout both North America and Europe, individual customers began to claim that their children had been ‘poisoned’ whilst playing with the end product. The threat of litigation was quickly leveled at KidCorp and the whole issue rapidly became a ‘full-blown’ child health scare. A range of pressure groups and legal damage specialists supported and acted to aggregate the individual claims and although similar accusations had been made before, the litigants and their supporters focused in on the recent changes made to the production process and, in particular, the increasing role of suppliers. '….it’s all very well claiming that you trust your suppliers but you simply cannot have the same level of control over another firm in another country. I am afraid that this all comes down to simple economics, that KidCorp put its profits before children’s health. Talk about trust……parents trusted this firm to look out for them and their families and have every right to be angry that boardroom greed was more important!' Legal spokesperson for the litigants, interviewed on UK TV consumer rights show. Under intense media pressure, KidCorp rapidly convened a high profile investigation into the source of the contamination. It quickly revealed that an ‘unauthorised’ chemical had been employed in an apparently trivial metal cleaning and preparation element of the SIS production process. Although, when interviewed by the US media, the Parent firm’s legal director emphasised there was 'no causal link established or any admission of liability by either party' KidCorp immediately withdrew their order and began to signal an intent to bring legal action against SIS and its Parent. This action brought an immediate end to production in this part of the operation and the inspection (and subsequent official and legal visits) had a crippling impact upon the productivity of the whole site. The competitive impact of the failure was extremely significant. After over a year of production, the new product accounted for more than a third (39%) of the factory’s output. In addition to major cash-flow implications, the various investigations took up lots of managerial time and the reputation of the firm was seriously affected. As the site operations manager explained, even their traditional customers expressed concerns. 'It’s amazing, but people we had been supplying for thirty or forty years were calling me up and asking "[Manager’s name] what’s going on?" and that they were worried about what all this might mean for them … these are completely different markets!' 179 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TEACHING NOTE – SAUNDERS INDUSTRIAL SERVICES This example describes the formulation and implementation of an operations strategy: with the primary focus on the risks associated with OS process. This traditionally low volume manufacturing firm, which had been operating for many years, faced changed competitive circumstances and under ‘parental’ pressure to diversify (and satisfy an established corporate client) it decided to embark on a new era of high volume manufacturing. Inevitably, this case also considers fit and sustainability themes and equally comprises more specific issues relating to product design and corporate operations parenting. Analysis In Chapter 10, a definitional model of operations-related risk (drawing upon the transformation model widely employed in operations analysis) was presented: • the potential for unwanted negative consequences from an operational event. This simple model can be used to portray what happened at SIS in a structured and largely chronological manner. CAUSATIVE NEGATIVE CONSEQUENCE SIS began life as the classic family firm. By 1995, it had doubled in size again and now (as part of a UK-owned industrial conglomerate since 1985) employed approximately 600 people and had a turnover approaching $210 million. This process was not very successful but eventually culminated in a 1994 tender to become the preferred supplier for a metallic element of a child’s toy. In 1995, KidCorp (already a customer for other businesses owned by the corporate parent) selected SIS to complete the design and begin trial production. After visiting the firm, KidCorp purchasing managers had been impressed by the firm’s depth of experience and commitment to quality. Unfortunately, SIS effectively commissioned a production method that would prove to be entirely inappropriate for the toy market but it was not until mid-1997 (16 months later) that any indication of problems began to emerge. Causative Event The factors contributing to industrial failures are summarised as a generic set of Human, Organisational and Technological (HOT) variables. • Organisational. In 1992, in the midst of difficult economic times and widespread industrial restructuring, they had been ‘strongly encouraged’ by their corporate parent to bid for 180 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual higher volume and lower margin work. Similarly, KidCorp were an important corporate client and there was clearly pressure for SIS to help further develop this relationship. • Technological. The SIS designers received an outline specification from KidCorp during the bid. A team of engineers and managers confirmed that the product could and would be manufactured using an up-scaled version of current production processes. The key technical challenge appeared to be accessing sufficient capacity. Fortunately, the Parent was very supportive (see above) and authorised capital expenditure plans. • Human. There is a great deal of ongoing legal argument around whether an individual engineer made the wrong design assumptions when responding to the original brief. Although the production challenge was widely accepted as simply being one of scale, (an opinion apparently shared by KidCorp and Parent) it was left to one specific senior engineer to actually sign both the final bid and technical completion documentation. Similarly, the causative events can be characterised using the generic resource categories/ decision areas that underpin the OS matrix. CAPACITY SUPPLY NETWORK PROCESS TECHNOLOGY DEVELOPMENT & ORGANISATION As well as allocating dedicated capacity to a specific customer, the KidCorp production involved a shift from low volumes and multiple customers to high volume and single customer. Underpinning the decision to invest heavily with SIS was the KidCorp decision to adopt a single source or ‘partnerships’ supply network management initiative. It was superficial product similarities that led to an inappropriate production process being employed. Ultimately, however, it is the process technology that stands accused of causing health problems. An assumed similarity between existing and new product lead to insufficient exploration of specific design brief. As a result of design errors, the quality control systems introduced proved to be inappropriate. What is the Question? As mentioned earlier, this case is illustrative of a number of different operations strategy issues. It is possible to apply the OS matrix but the case also requires consideration of the dynamic impact of adding capability, meeting requirements, etc. over time. In this case, the resource/requirement ‘fit’ graph can be very helpful. Issues of ambiguity and uncertainty are of course central to the case but an indicative key question might be, 'What operational risks did SIS face when deciding to become a strategic supplier for KidCorp and what control problems did they encounter in implementing this strategy (pre and post investigation)?' Options/Discussion Criteria This case provides a basis for assessing the three different ‘risk’ elements, which need active consideration in any operations strategy process: 181 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual 1. Firstly, operations strategy must consider how ‘actors’ (managers and staff, as well as current and potential customers, regulators, etc.) understand and cope with risk. The cognition of risk is therefore particularly significant because individuals rarely deal with risk in a rational manner. 2. Secondly, perceived pure and speculative risks are strongly influenced by the internal (operational system) and external (customer and stakeholder) operating context. 3. Finally, because, by definition, a risk is something with unwanted consequences, it is something that we normally seek to control. However, the control of risk covers a range of different strategies including prevention, mitigation and if the worst comes to the worst, failure recovery. Evaluation level of mark et requirements Before addressing the specific nature of the risks inherent in the operations strategy process, it is helpful to develop a map of the firms’ resource and requirement position over time. m1 1 2 m0 0 cp2 cp0 0 cp1 level of operational capability Cognition The product development process had been intended to develop (shifting from point 0) knowledge of new market requirements (m0 to m1), leverage and refine existing product engineering and production (new capital investment, etc.) capabilities (cp0 to cp1) and establish a partnership-specific customer relationship. After over a year of production, the new product accounted for almost half of the SIS factory output and appeared to be a great success – in other words, an exact fit. However, in reality (albeit only later established by external investigation) this capability/requirements match was not exact because it was underpinned by an ‘unauthorised’ chemical employed in an apparently trivial metal cleaning and preparation element of the SIS production process (Point 1). This cognitive mismatch might be explained in a number of ways, for instance: 182 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • The apparent familiarity of the product/process perhaps led to key managers/engineers being insensitive to ‘obvious’ technological development risks. • Although KidCorp was in many ways the same kind of customer that SIS was very used to dealing with, the end consumer market was very different to any they had served, no matter how indirectly, before. • The parental pressure to serve a key corporate client may have brought distorting time and political pressure to bear on the development decision-making process. Context Once end customers began to claim that their children had been ‘poisoned’ whilst playing with the end product, a range of pressure groups and legal damage specialists ('I am afraid that this all comes down to simple economics, that KidCorp put its profits before children’s health!') acted to aggregate the individual claims. The changing operating context had a significant impact upon SIS (point 2): • Under intense media pressure, KidCorp rapidly convened a high profile investigation into the source of the contamination. In addition to major cash-flow implications, this (and subsequent) investigations took up lots of managerial time and the reputation of SIS (and by association its parent) was seriously affected: 'people we had been supplying for thirty or forty years were calling me up and asking "what’s going on?"’. • The litigants quickly focused in on the recent changes made to the supply network and the subsequent investigation quickly revealed the ‘unauthorised’ chemical. KidCorp immediately withdrew their order and began to signal intent to bring legal action against SIS and its Parent. This action brought an immediate end to production in this part of the operation and the inspection (and subsequent official and legal visits) had a crippling impact upon the productivity of the whole site. Control (and Coupling) Strategies A matrix can be used to link notions of control and ‘coupling’. The vertical axis is a conflation of the discussion of operational events and negative outcomes into a generic negative impact scale. The horizontal axis is the degree of systemic coupling. The diagonal between the two dimensions suggests a limit to the applicability of mitigation strategies (and hence a retention of some degree of control) before the advent of probable crises and a reliance on recovery strategies. The upper left-hand corner of the matrix indicates that it is likely, following a major and complex negative operational outcome, that there will be almost no scope for mitigating negative competitive consequences. In these cases recovery strategies will predominate whilst recognising a tendency for such failures to become more tightly coupled as they trigger stakeholder and media interest, etc. The bottom-right corner of the matrix indicates how, in a tightly coupled system, only the most minor negative outcomes can be tolerated before negative consequences are realised, mitigation becomes impossible and recovery is necessary. 183 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Degree of coupling in the organisation loose tight Causal event (failure) major (complex) minor (simple) Applied to the case study (see figure above), it is interesting to highlight two different positions on the matrix. The first location (lighter shaded) indicates the perceived general control position prior to the failure incident (this case involved a significant degree of control judgment error) and the second (darker shaded) indicates one more realistic interpretation of the ‘actual’ position following the realisation of negative consequences. The familiarity of the process gave SIS a sense of confidence that they knew what could go wrong and who would be affected by it. This had worked well for them in the past but, under pressure from the corporate parent, they misinterpreted the level of similarity between traditional products and the new market. This led them to infer a level of control over both the product development and manufacturing processes that was misplaced and also meant that they underestimated the nature of the failure and the negative consequences. Equally, the shift towards higher volume supply for a single client, who in turn distributed the end product, globally changed the production systems’ (i.e. internal) coupling characteristics. Moreover, following the failure (and allegations of failure), the firm was subject to intense corporate, regulatory, legal, pressure group and international media investigation. This radically changed the nature of external systemic coupling. 184 © Nigel Slack and Michael Lewis 2012 GENEVA CONSTRUCTION AND RISK ‘This is not going to be like last time. Then, we were adopting an improvement programme because we were told to. This time it’s our idea and, if it’s successful, it will be us that are telling the rest of the group how to do it’. (Tyko Mattson, Six Sigma Champion, GCR) Tyko Mattson was speaking as the newly appointed ‘Champion’ at Geneva Construction and Risk Insurance, who had been charged with ‘steering the Six Sigma programme until it is firmly established as part of our on-going practice’. The previous improvement initiative that he was referring to dated back many years to when GCR’s parent company, Wichita Mutual Insurance, had insisted on the adoption of totally quality management (TQM) in all its businesses. The TQM initiative had never been pronounced a failure and had managed to make some improvements, especially in customers’ perception of the company’s levels of service. However, the initiative had ‘faded out’ during the 1990s and, even though all departments still had to formally report on their improvement projects, their number and impact was now relatively minor. History The Geneva Construction Insurance Company was founded in 1922 to provide insurance for building contractors and construction companies, initially in German-speaking Europe and then, because of the emigration of some family members, to the USA, North America. The company had remained relatively small and had specialised in housing construction projects until the early 1950s when it had started to grow, partly because of geographical expansion and partly because it has moved into larger (sometimes very large) construction insurance in the industrial, oil, petrochemical and power plant construction areas. In 1983 it had been bought by the Wichita Mutual Group and had absorbed the group’s existing construction insurance businesses. By 2000 it had established itself as one of the leading providers of insurance for construction projects, especially complex, high-risk projects, where contractual and other legal issues, physical exposures and design uncertainty needed ‘customised’ insurance responses. Providing such insurance needed particular knowledge and skills from specialists including construction underwriters, loss adjusters, engineers, international lawyers and specialist risk consultants. Typically, the company would insure losses resulting from contractor failure, related public liability issues, delays in project completion, associated litigation, other litigation (such as ongoing asbestos risks) and negligence issues. The company’s headquarters were in Geneva and housed all major departments including, sales and marketing, underwriting, risk analysis, claims and settlement, financial control, general admin, specialist and general legal advice, and business research. There were also 37 local offices around the world, organised into four regional areas; North America, South America, Europe Middle East and Africa and Asia. These regional offices provided localised help and advice directly to clients and also to the 890 agents that GCR used worldwide. 185 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The previous improvement initiative When Wichita Mutual had insisted that CGR adopts a TWM initiative, it had gone as far as to specify exactly how it should do it and which consultants should be used to help establish the programme. Tyko Mattson shakes his head as he describes it. ‘I was not with the company at that time but, looking back; it’s amazing that it ever managed to do any good. You can’t impose the structure of an improvement initiative from the top. It has to, at least partially, be shaped by the people who are going to be involved in it. But everything had to be done according to the handbook. The cost of quality was measured for different departments according to the handbook. Everyone had to learn the improvement techniques that were described in the handbook. Everyone had to be part of a quality circle that was organised according to the handbook. We even had to have annual award ceremonies where we gave out special “certificates of merit” to those quality circles that had achieved the type of improvement that the handbook said they should’. The TQM initiative had been run by the ‘Quality Committee’, a group of eight people with representatives from all the major departments at head office. Initially, it had spent much of its time setting up the improvement groups and organising training in quality techniques. However, soon it had become swamped by the work needed to evaluate which improvement suggestions should be implemented. Soon the work load associated with assessing improvement ideas had become so great that the company decided to allocate small improvement budgets to each department on a quarterly basis that they could spend without reference to the quality committee. Projects requiring larger investment or that had a significant impact on other parts of the business still needed to be approved by the committee before they were implemented. Department improvement budgets were still used within the business and improvement plans were still required from each department on an annual basis. However, the quality committee had stopped meeting by 1994 and the annual award ceremony had become a general communications meeting for all staff at the headquarters. ‘Looking back’, said Tyko, ‘the TQM initiate faded away for three reasons. First, people just got tired of it. It was always seen as something extra rather than part of normal business life, so it was always seen as taking time away from doing your normal job. Second, many of the supervisory and middle management levels never really bought into it, I guess because they felt threatened. Third, only a very few of the local offices around the world ever adopted the TQM philosophy. Sometimes this was because they did not want the extra effort. Sometimes, however, they would argue that improvement initiatives of this type may be OK for head office processes, but not for the more dynamic world of supporting clients in the field’. The Six Sigma initiative Early in 2005 Tyko Mattson, who for the last 2 years had been overseeing the outsourcing of some of GCR’s claims processing to India, had attended a conference on ‘Operations Excellence in Financial Services’, and had heard several speakers detail the success they had achieved through using a Six Sigma approach to operations improvement. He had persuaded his immediate boss, Marie-Dominique Tomas, the head of claims for the company, to allow him to investigate its applicability to GCR. He had interviewed a number of other financial services who had implemented Six Sigma as well as a number of consultants and in September 2005 had submitted a report entitled ‘What is Six Sigma and how might it be applied in GRC?’ Extracts from this are included in Appendix 1. Marie-Dominique Tomas was particularly concerned that they should avoid the mistakes of the TQM initiative. ‘Looking back, it is almost embarrassing 186 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual to see how naive we were. We really did think that it would change the whole way that we did business. And although it did produce some benefits, it absorbed a large amount of time at all levels in the organisation. This time we want something that will deliver results without costing too much or distracting us from focussing on business performance. That is why I like Six Sigma. It starts with clarifying business objectives and works from there’. By late 2005 Tyko’s report had been approved both by GCR and by Wichita Mutual’s main board. Tyko had been given the challenge of carrying out the recommendations in his report, reporting directly to GCR’s executive board. Marie-Dominique Tomas was cautiously optimistic, ‘It is quite a challenge for Tyko. Most of us on the executive board remember the TQM initiative and some are still sceptical concerning the value of such initiatives. However, Tyko’s gradualist approach and his emphasis on the “three pronged” attack on revenue, costs, and risk impressed the board. We now have to see whether he can make it work’. 187 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Appendix – Extract from ‘What is Six Sigma and how might it be applied in GCR?’ Six Sigma – pitfalls and benefits Some pitfalls of Six Sigma It is not simple to implement, and is resource hungry. The focus on measurement implies that the process data is available and reasonably robust. If this is not the case it is possible to waste a lot of effort in obtaining process performance data. It may also over-complicate things if advanced techniques are used on simple problems. It is easier to apply Six Sigma to repetitive processes – characterised by high volume, low variety and low visibility to customers. It is more difficult to apply Six Sigma to low volume, higher variety and high visibility processes where standardisation is harder to achieve and the focus is on managing the variety. Six Sigma is not a ‘quick fix’. Companies that have implemented Six Sigma effectively have not treated it as just another new initiative but as an approach that requires the long-term systematic reduction of waste. Equally, it is not a panacea and should not be implemented as one. Some benefits of Six Sigma Companies have achieved significant benefits in reducing cost and improving customer service through implementing Six Sigma. Six Sigma can reduce process variation, which will have a significant impact on operational risk. It is a tried and tested methodology, which combines the strongest parts of existing improvement methodologies. It lends itself to being customised to fit individual company’s circumstances. For example, Mestech Assurance has extended their Six Sigma initiative to examine operational risk processes. Six Sigma could leverage a number of current initiatives. The risk self-assessment methodology, Sarbanes Oxley, the process library, and our performance metrics work are all laying the foundations for better knowledge and measurement of process data. Six Sigma – key conclusions for GCR Six Sigma is a powerful improvement methodology. It is not all new but what it does successfully is to combine some of the best parts of existing improvement methodologies, tools and techniques. Six Sigma has helped many companies achieve significant benefits. Six Sigma could help GCR significantly improve risk management because it focuses on driving errors and exceptions out of processes. 188 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Six Sigma has significant advantages over other process improvement methodologies. It engages senior management actively by establishing process ownership and linkage to strategic objectives. This is seen as integral to successful implementation in the literature and by all companies interviewed who had implemented it. It forces a rigorous approach to driving out variance in processes by analysing the root cause of defects and errors and measuring improvement. It is an ‘umbrella’ approach, combining all the best parts of other improvement approaches. Implementing Six Sigma across GCR is not the right approach Companies that are widely quoted as having achieved the most significant headline benefits from Six Sigma were already relatively mature in terms of process management. Those companies, who understood their process capability, typically had achieved a degree of process standardisation and had an established process improvement culture. Six Sigma requires significant investment in performance metrics and process knowledge. GCR is probably not yet sufficiently advanced. However, we are working towards a position where key process data are measured and known and this will provide a foundation for Six Sigma. A targeted implementation is recommended because: Full implementation is resource hungry. Dedicated resource and budget for implementation of improvements is required. Even if the approach is modified, resource and budget will still be needed, just to a lesser extent. However, the evidence is that the investment is well worth it and pays back relatively quickly. There was strong evidence from companies interviewed that the best implementation approach was to pilot Six Sigma, and select failing processes for the pilot. In addition, previous internal piloting of implementations has been successful in GCR – we know this approach works within our culture. Six Sigma would provide a platform for GSR to build on and evolve over time. It is a way of leveraging the on-going work on processes, and the risk methodology (being developed by the Operational Risk Group). This diagnostic tool could be blended into Six Sigma, giving GCR a powerful model to drive reduction in process variation and improved operational risk management. Recommendations It is recommended that GCR management implement a Six Sigma pilot. The characteristics of the pilot would be as follows: • A tailored approach to Six Sigma that would fit GCR’s objectives and operating environment. Implementing Six Sigma in its entirety would not be appropriate. 189 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • The use of an external partner: GCR does not have sufficient internal Six Sigma, and external experience will be critical to tailoring the approach, and providing training. • Establishing where GCR’s sigma performance at present. Different tools and approaches will be required to advance from 2 to 3 Sigma than those required to move from 3 to 4 Sigma. • Quantifying the potential benefits. Is the investment worth making? What would a 1 Sigma increase in performance vs. risk be worth to us? • Keeping the methods simple, if simple will achieve our objectives. As a minimum for us that means Team Based Problem Solving and basic statistical techniques. Next steps 1. Decide priority and confirm budget and resourcing for initial analysis to develop a Six Sigma risk improvement programme in 2006. 2. Select external partner experienced in improvement and Six Sigma methodologies. 3. Assess GCR current state to confirm where to start in implementing Six Sigma. 4. Establish how much GCR is prepared to invest in Six Sigma and quantify the potential benefits. 5. Tailor Six Sigma to focus on risk management. 6. Identify potential pilot area (s) and criteria for assessing its suitability. 7. Develop a Six Sigma pilot plan. 8. Conduct and review the pilot programme. Questions 1. How does the Six Sigma approach seem to differ from the TQM approach adopted by the company almost 20 years ago? 2. Is Six Sigma a better approach for this type of company? 3. Do you think Tyko can avoid the Six Sigma initiative suffering the same fate as the TQM initiative? 190 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Teaching note – Geneva Construction and Risk (GCR) Case synopsis Geneva Construction and Risk (GCR) is an insurance company that specialises in providing insurance for construction projects, especially complex, high risk projects, where contractual and other legal issues, physical exposure and design uncertainty need ‘customised’ insurance responses. It is part of the larger Wichita Mutual Insurance Group. The case describes the company’s intention to adopt a Six Sigma improvement methodology. Unfortunately, the company’s experience with ‘quality initiatives’ is not good. Some years ago Wichita Mutual had instructed all companies in its group to adopt a TQM initiative. It had done this in a very prescriptive way by issuing a handbook with detailed instructions of how TQM was to be implemented throughout the group. Although the TQM initiative had never been formally pronounced a failure, it had faded over the years without having the overall impact that once was hoped of it. This time, Tyko Mattson, the Six Sigma champion at GCR, is convinced that an improvement initiative based on Six Sigma principles will be more of a success. The case describes the previous TQM initiative and why it is hoped that the Six Sigma initiative will prove more effect. Extracts from a document prepared by Tyko Mattson are included in the case. This describes his views of some of the advantages and disadvantages of Six Sigma as an improvement approach and makes recommendations as to how it can be applied at GCR. Using the case This is a rich and complex case that can be used in a number of ways in class. How it is used will depend on whether the topics of TQM and Six Sigma have been taught prior to running the case or not. If this case is used as in introduction to improvement and improvement initiatives, then the debrief should provide an opportunity for presenting the key points of both TQM and Six Sigma. If the case is used after these topics have been treated in class, then the case can be used to develop some of the issues concerning the differences between the two approaches, the similarities between the two approaches, and the difficulty in implementing initiatives of this type. It is recommended that when the class contains relatively inexperienced students with little knowledge of the realities of improvement initiatives such as these, the case is used to introduce some of the main characteristics of TQM and Six Sigma. Where the majority of the students will have experience of this type of initiative, it can be used to treat some of the more organisational problems of implementing improvement initiatives. Notes on questions Question 1 – How does the Six Sigma approach seem to differ from the TQM approach adopted by the company almost 20 years ago? This is an opportunity to discuss the main differences between TQM and Six Sigma, both in abstract and in terms of how CGR sees each approach. Some points that can be brought out regarding each approach are as follows. 191 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TQM • The handbook said that everyone must be involved. • The handbook said that all companies in the group must organise the TQM initiative in the same way ‘according to the handbook’. • Emphasis was put on measuring the cost of quality. • Similar improvement techniques were used throughout the group. • Everyone was assigned as part of a quality circle. • Annual award ceremonies were conducted where ‘certificates of merit’ were awarded. • The initiative was run by a company-wide quality committee. • The quality committee organised groups and quality training. It also evaluated whether the suggestions for improvements should be implemented and allocated budget to their implementation. • Eventually the evaluation procedures were taking up so much time an effort that the company moved towards a limited form of self-certification involving small improvement budgets on a group-by-group basis. • Improvement budgets and improvement plans are still used in the company. • The annual awards ceremony is now a ‘general communications’ meeting. Six Sigma The definition of Six Sigma as described in the text is …‘Six Sigma is a comprehensive and flexible system for achieving, sustaining and maximising business success. Six Sigma is uniquely driven by close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving, and reinventing business processes’. • It is a process-centred approach that includes process design, performance measurement, continuous improvement (using the DMAIC cycle), statistical process control, quantitative and evidence-based decision making, an emphasis on the negative effects of process variation, and the ‘normalisation’ of processes using the ‘defects per million opportunities’ (DPMO) principle. • GCR is also wanting to use Six Sigma to tackle operational risk. They believe it to be ‘resource hungry’. • They accept it is not a ‘quick fix’. • They believe it to be harder for low volume, non-standardised processes. They believe that the Six Sigma approach fits well with the other initiatives in the company. 192 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • They accept that Six Sigma is not new as such. • They see a major advantage of Six Sigma being that it engages senior management by establishing process ownership and linking process performance to strategic objectives. They are attracted by the idea that it is a rigorous approach. • They believe it to be an ‘umbrella’ approach that can incorporate the other initiatives. The previous two lists should be generated by asking the class to call out how each initiative is (and was) seen by the company. Develop these two lists on different parts of the board. At this point we find it useful not to make too much comment on each of the points. Try and reach consensus where students disagree about a point but do not engage in too much debate. If these points are debated at this stage, it is easy to lose sight of the overall direction of the case and the teaching points that one wishes to emerge. Only at that point is it worth going back to the question and asking how Six Sigma is different from TQM in the context of CGR. The debate at this point can be wide ranging and will depend on the nature of the class. However, this is the time to go over some of the points made previously and have a debate on them individually. For example, see the following. • Both TQM and Six Sigma can be interpreted in different ways. TQM was characterised by several ‘quality gurus’, all of whom had a slightly different approach and emphasised different points. Similarly, Six Sigma has no single definition (the one we quoted earlier is typical but not accepted by everyone). Nevertheless there are some clear differences between the two approaches. • The fact that the previous initiative was imposed from above is very important in this case. It is difficult to separate the two issues of, on one hand, how the improvement approach was introduced to the company, and on the other hand, the intrinsic merit of each approach. It may be that the best and most appropriate improvement approach would still have failed because it was imposed on the company. • Tyko is right (more or less) in the way he sees Six Sigma as a collection of previously ‘tried and tested’ techniques and methods. • He is also right to say that Six Sigma can be ‘resource hungry’. (However, so is TQM). Yet, there is no recognition in the case of just how resource hungry Six Sigma can be. A fundamental part of Six Sigma is the idea of internal improvement champions/consultants (called Black Belts and Master Black Belts) who are relieved of all line duty. This is an extra cost. Similarly, the degree of training recommended by most consultants in this area (admittedly because it is in their interests to do so) is very large. Tyko’s view that Six Sigma will fit well within the company’s culture is an important one. • The idea that Six Sigma will ‘fit well with other company initiatives’ may be worth debating. At worst, it can encourage competition between alternative approaches (though some authorities believe this can be positive). Arguably, it is more important to ensure that there is some degree of compatibility and integration between the different initiatives. • The idea that, because Six Sigma is a collection of ideas that have been around for some time, it can be an ‘umbrella’ approach is worth debating here. Although Six Sigma can be 193 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual seen in this way, it does have a number of themes running through it that cannot be compromised, including process perspective, linking process objectives both to customer needs and strategic intention, a rigorous approach to problem solving that is not afraid to use quantitative techniques, and the idea of continuous improvement. Question 2 – Is Six Sigma a better approach for this type of company? Try opening this question up first before making any comment on it. It can provoke a vigorous debate. Often, different students will take different views. This is good for learning because the question is actually rather simplistic. This may be the time to promote a ‘side debate’ on the nature of improvement initiatives generally. All improvement approaches reflect the time in which they emerged. Because of this, TQM now seems dated, yet it still contains many good points, and many that have been included within Six Sigma. We use this stage in the debrief to move students towards accepting that none of these approaches are the ultimate recipe for improving operations. What is important is that they are not presented as panaceas (there is some evidence that CGR may be falling into this trap). If they are, inevitably there will be a backlash against them in time and the useful activities that they have promoted will be discarded along with those that are less useful. However, there is a difference between the two approaches. Broadly, Six Sigma is less challenging and revolutionary than was TQM in its day, but does reflect the more challenging business environment that has emerged in recent years. It also places a great deal more emphasis on quantitative approaches such as statistical process control. This may appeal to some industries more than other. Insurance for example is essentially a quantitative industry that relies on actuarial statistics to make pricing judgements. Perhaps this is why the evidence-based quantitative approach of Six Sigma is attractive to such companies. The paradox here is that, although Six Sigma may be more appropriate for this kind of company, it may be that it is appropriate simply because it is their own idea, rather than one that has been imposed on them. This could be a more important factor than any more ‘rational’ reasons for adopting the approach. Question 3 – Do you think that Tyko can avoid the Six Sigma initiative suffering the same fate as the TQM initiative? Tyko believes that there were three reasons why the TQM initiative faded away. • People got tired of it and it was always seen as something extra rather than part of normal business life. • Middle management never bought into it because they felt threatened. • Only a very few of the local offices around the world adopted the TQM philosophy. It is useful to debate each of these points in turn. It faded away and it was just extra work – These are separate points, although related. People will get tired of any initiative if it ceases to have value. Unless everyone can see some kind of benefit for the actions they are taking, then it is inevitable that the idea will fade away. The fact that TQM did not work in this respect is not necessarily a problem with TQM as such. Rather it 194 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual is the way it was implemented. Again, at this point a debate about the nature of improvement initiatives could be useful. Middle management didn’t accept because they felt threatened – Middle management often feel threatened by these initiatives for a very simple reason – they are threatened. The idea of devolving improvement decision making down the hierarchical structure of the organisation is clearly going to be a real threat to those people who, hitherto, had assumed this role. A debate on this issue could go on for a long time, and is (strictly) part of other courses. However, it may be worth having a debate on the changing role of middle management (from task decision making to process decision making, from administration to coaching and developing, etc.). Very few local offices adopted the TQM philosophy – This is a common problem with all improvement initiatives. Because of the geographical spread of local offices it is more difficult to engage them with any new idea. However, what may be a more interesting point of debate is the idea that the TQM initiative was less appropriate to them. One interpretation of this point is that the local offices were saying because they were more of a sales and support operation, the (in our terms) high visibility processes that they ran were less susceptible to improvement initiatives that were designed for ‘back-office’ processes. Whether Six Sigma is more appropriate for such high visibility processes is debatable. Some practitioners still concentrate on low visibility, back-office operations in the way they advice on Six Sigma implementation. Yet, because it is a process-focused initiative, it should be able to recognise differences between processes. Certainly the DPMO idea within Six Sigma is partly a recognition that processes are different and therefore must be judged in different ways. Some people would argue that one of the great advantages of Six Sigma over TQM is the greater emphasis on strategic objectives. Many TQM initiatives focussed very much on ‘the customer’ alone. This may not have been how TQM was seen by many of its founders, but that is the way it was often implemented. By contrast, Six Sigma looks at the needs and contribution of three elements, • the customer, • the processes that create the services for the customer, and • the overall strategic objectives of the company. This is a far more realistic context in which to improve operations. However, it is always worth finishing off the debrief by reminding the class that in a few years time there will be yet another improvement initiative. Will we be making the same criticisms about Six Sigma when that time comes? 195 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 1 Operations strategy – developing resources for strategic impact Chapter aims This first chapter is a relatively long chapter because Chapter 1 of Slack and Lewis covers several important points that are fundamental to developing an understanding of operations strategy, why operations strategy is important and how one can take four distinct but related perspectives on the topic. This chapter aims to • Show why the concept of operations strategy is important and relevant to any business or enterprise • Explain the four perspectives on operations strategy • Demonstrate how the performance objectives of operations can be related to the decision areas of operations strategy Studying operations strategy You may find operations strategy to be more difficult conceptually and in some more ways more abstract than operations management, but do not worry too much. It does take a while to understand the difference between operations management and operations strategy. Read Chapter 1 carefully, then work through this guide, and if you still have difficulty, try moving forward with the guide and then return periodically to the first chapter. Hopefully, by the end of all the chapters you should have a reasonable understanding of the topic! The chapter poses a number of questions that anyone wishing to understand the nature of operations strategy needs to address. These are • What is ‘operations’ and why is it so important? • What is strategy? • What is operations strategy? • How should operations reflect overall strategy? • How can operations strategy learn from operational experience? 196 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • How do the requirements of the market influence operations strategy? • How can the intrinsic capabilities of an operation’s resources influence operations strategy? • What is the difference between the ‘content’ and the ‘process’ of operations strategy? • What are operations strategy performance objectives? • What are operations strategy decision areas? • How do performance objectives relate to decision areas? For many people who have studied operations management the first of these questions will have been covered in your operations management course. Also, if you have studied general (or business, or corporate) strategy, the second question will be familiar. Because of this we will treat these two questions only very briefly in this guide. But the other questions are likely to be new to you and will form the structure of the remainder of this part of the study guide. What is ‘operations’? Operations is important because all businesses depend on their operations to deliver the services and products on which they depend. No matter how good a strategy, it is rendered impotent unless the business’s day-to-day operations can actually delivery what the strategy requires. The basic model used in operations management to explain how operations management works is the input–transformation–output model. This model can be extended to demonstrate how operations can contribute at different levels of analysis from strategic through to operational. This is treated under the heading ‘Three levels of input–transformation–output’ in Chapter 1. Essentially the model demonstrates that, no matter what level of analysis is taken, operations is concerned with the capability of individual entities (whole operations, processes or individual resources within a process) and the relationship between them. This is shown in Figure 1.1. 197 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What is strategy? Actually the text does not provide a specific definition of ‘strategy’, it simply discusses what characterises strategic decisions. Yet there is no shortage of definitions. In fact that is the problem. As the text also makes clear there are many definitions. Here are a few (in no particular order). Strategy is… • A scheme: an elaborate and systematic plan of action • A long-term plan of action designed to achieve a particular goal • A broad non-specific statement of an approach to accomplishing desired goals and objectives • A general plan or direction selected to accomplish specified objectives • A long-term plan for success, intended to achieve an advantage. It includes key milestones and targets • The differentiating activities an organisation pursues to gain competitive advantage • A systematic plan, consciously adapted and monitored, to improve one's performance • A comprehensive plan or action orientation that identifies the critical direction and guides the allocation of resources of an organisation 198 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • A planned, deliberate procedure that is goal-oriented (has an identifiable outcome) and achieved with a sequence of steps • An approach taken that will affect the overall direction of the organisation • A plan or method including options and priorities towards the achievement of a defined goal or objective These definitions are both short and, to some extent diverse, they do convey the overall idea of what strategy is. They also give a general idea about what operations strategy is. Substitute the word ‘operation’ for ‘organisation’ and one has a working definition of operations strategy. The decisions taken as part of a company’s operations strategy are considered strategic because they • Are widespread in their effect and so are significant in the part of the organisation to which the strategy refers • Define the position of the organisation relative to its environment • Move the organisation closer to its long-term goals. However, a ‘strategy’ is more than a single decision; it is a total pattern of the decisions. Similarly, a company’s operations strategy is shown in the pattern of decisions that the organisation takes to develop its operations resources. Such decisions include the magnitude and nature of its total capacity, the way in which it relates to customers, competitors, suppliers and partner operations, its approach to acquiring or developing process technology, the way in which it organises and develops its resources, and so on. ‘Operations’ is not always ‘operational’ As the text points out, operations strategy does seem a contradiction in terms. Yet, as it also points out, one should not confuse ‘operations’ with ‘operational’. Operational is not strategic, in fact it is the very opposite of strategic (it means detailed, localised, short term, day-to-day). But ‘operations’ is different, it is ‘the activity of managing the resources and processes that produce and deliver goods and services’. So operations strategy looks at the strategic implications of how the operations activity is managed. It is concerned with what the operation has to do in order to meet current and future challenges, and with the long-term development of operations resources and processes, so that they can provide the basis for a sustainable advantage. Any business that fails to appreciate the strategic impact that effective operations management can have is missing a huge opportunity to establish a competitive advantage. The influence of an organisation’s aspirations for its operations as well as the operations function’s ability to contribute to strategic positioning are both fundamental to its long-term success. Both issues are also undeniably strategic. This is not to downplay the importance of ‘operational’ operations management. It is of course important to get the details right and do so on a dependable day-to-day basis. In fact, it is the accumulation of day-to-day experience which can build-up the operations capabilities which go towards providing the strategic operations advantage. This is the paradox of running a successful operation. It has to be good at both the day-to-day details and the broader strategic issues. In fact it has to be able to connect the operational and the strategic aspects of operations together. 199 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual How is operations strategy different from operations management? While there are many ways in which a strategic perspective on operations can be distinguished from the more operational perspective of operations management, four types of difference are particularly useful. Timescale – Operations management is largely concerned with short to medium timescales, though what constitutes short or medium will vary for different industries. Nevertheless, time horizons are relatively short. A typical decision in a food factory would be, ‘what demand fluctuations do we have to deal with over the next few months?’ Operations strategy is concerned with the longer term. A typical decision would be, ‘when should we plan to add further capacity so that we can meet rising forecast demand?’ Level of analysis – Operations management is largely concerned with managing resources within and between micro operations (departments, work units, etc.) A typical decision might be, ‘where should we position each product category within our department store?’ The boundaries of the decision are the walls of one store (in this case), while the ‘building blocks’ of the decisions are the units or departments. Operations strategy is more concerned with decisions affecting a wider set of the organisation’s resources. Typical decisions would be, ‘How many stores should we have, where should we locate them and how should we supply them?’ Here the ‘building blocks’ of the decision are whole stores and the transportation network which supplies them. Level of aggregation – Operations management is concerned with the details of how products and services are produced. Individual sets of resources are treated separately, as the component parts of the operation. A typical decision for a firm of accountants might be, ‘How do we provide tax advice to the small business sector in Antwerp?’ To answer the question individual human skills, specific technology capabilities and separate physical locations must be considered. Operations strategy, on the other hand, brings together and consolidates such details into broader issues. A typical question would be, ‘what is our overall business advice capability compared with our other European activities?’ Here we are concerned with a general capability to provide a broad category of service within a wider geographic area. Level of abstraction – Operations management is concerned largely with what is immediately recognisable and tangible. In a health care organisation, for example, it would include concrete issues such as, ‘how do we improve our purchasing procedures?’ The purchase orders, information flow and physical inventory associated with purchasing, can all be readily observed. Operations strategy, on the other hand, often deals with more abstract issues. So, for example, the question, ‘should we develop strategic alliances with selected medical products suppliers?’ again deals with purchasing but in a manner which touches on the philosophy and values of the company. One cannot observe the concept of a strategic alliance directly, only the effects of it. Does operations strategy apply to service as well as manufacturing organisations? Yes. It is no accident that the title of the book is ‘Operations Strategy’ rather than the, far more common, ‘Manufacturing Strategy’. Of course there are differences between different types of business. No one is denying that running a hospital is not the same as running an automobile plant. But, there are many common issues, common decisions and common principles. It is the commonality in the approach to operations strategy analysis which is stressed throughout the book. Yet whereas operations management is now a reasonably well developed subject, operations strategy is, as yet, not. But the same forces that have moved manufacturing 200 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual management to operations management also apply to operations strategy. In most developed economies, manufacturing accounts for around 20 per cent or less of economic activity (see Figure 1.3). Admittedly, it is a very important 20 per cent, but the fact remains that the vast majority of business activities are concerned with trading services rather than trading products. This means of course that the vast majority of operations are concerned with producing service rather than producing products. The inescapable logic is that, if operations strategy is to be a useful concept, it must be at least as applicable to service operations as it is to manufacturing operations. Yet the history of the subject is deeply rooted in manufacturing. It is only relatively recently that books on the subject and university courses started to change their names to operations strategy rather than manufacturing strategy. Commentary on ‘AESSEAL’ example The trend towards ‘servitisation’ is not confined to the manufacturers of physical goods. It also applies to other sectors such as software development. Figure 1.4 shows how the proportion of revenue earned through services by four of the largest software developers increased between 1998 and 2002. Like any industry that has been operating for some years, the installed based of its products (products it has already sold and are being used by is 201 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual customers) is usually far, far higher than the value of new products sold each year. The obvious conclusion is that serving this installed base can provide a significant business opportunity. Combine that with the tendency of services to have higher margin than physical products and the business case for moving into services becomes overwhelming. So, the implication of all this is that you should not get too worried about any perceived difference between services and manufacturing. In many ways they are becoming the same thing. Think about the objective of operations strategy as putting the strategies in place that will ensure customers are well (and profitably) served both now and in the future. Does operations strategy apply to ‘not-for-profit’ organisations? Our belief is that all types of operation, for-profit or not-for-profit, service or manufacturing, free market-based or regulated market-based, will find the ideas of operations strategy useful. Forgive us though if we now lapse into ‘commercial’ terminology. It is not that we are discounting the value of other types of operation or the value of operations strategy ideas to these operations. It is just that the conventional type of operation which attempts to achieve an acceptable ‘return’ on its ‘investments’ through ‘market’ ‘competitiveness’ is the most useful base case on which to try out the various ideas explored in the course. We believe that the vast majority of these ideas translate relatively easily into other contexts. Some terms and ideas may have to be adapted, for example, the idea of competitive advantage seems alien to this sector. However, environmental charities compete for funding from government and private sources, police forces compete against increasingly sophisticated criminals, government think tanks compete with their new ideas against older more orthodox ideas (and against those of rival think tanks). All these organisations need to consider how they develop and deploy their resources to gain incremental competitive advantage. A related issue is the variety of ‘customers’ and stakeholders who need to be accommodated within non-profit organisations. This may not only add to the complexity of operations analysis and decision making, it can have other consequences. For example, the organisation may rely on several sources of funds (from its different stakeholders) which are associated with different objectives. For example, a local theatre may get its income from ticket sales (maximised by popular but low cost shows), its bar and restaurant (maximised by investing in the development of these facilities), local government (who will sustain funding if the theatre attracts a wide 202 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual cross-section of local society), national government (who sustain funding if the quality of performances is excellent), art charities (who may fund experimental theatre) and star performers (who generate extra sales but will come only if given some artistic freedom). In such an environment operations strategy decisions of where to allocate investment, how to set-up an effective organisational structure, which products (plays) to produce, and so on, are likely to be slow, complex, political and uncertain. Also an important category of stakeholder may be the staff themselves. Not only in the normal sense that staff have a share and an interest in the success of the organisation but also because many people could be giving their contributions on a voluntary basis. This gives an extra emphasis to the need to treat staff sensitively. It may largely be their beliefs which provide their motivation and they may demand the freedom to express and implement their beliefs. The C suit perspective Slack and Lewis introduce what is an unconventional view of operations strategy, namely that many of the concepts and approaches used in operations strategy (and explained in the text and these notes), can also be used to develop any functional strategy. This is because any function produces services, on behalf of, or directly for, the rest of the business. Some are relatively simple; others are more multifaceted and difficult. But all these services are produced using processes, and developing processes is essentially what ‘operations’ is about. It is surprising, therefore, that executives in non-operations functions have traditionally devoted relatively little time and effort to making sure that their processes produce services that are practical, responsive, (where necessary) flexible and produced efficiently. It is not as though these process skills are elusive. It is what the operations function is supposed to be an expert at. Of course, operations have had decades to come to terms with the many new ideas that have emerged in process management. But this is could be a huge advantage for non-operations functions. It means that we can learn from their experience and adapt process management approaches to the needs of finance. Thankfully, most companies have now come to understand the importance of process. This is because they have realised that because effective process management gives the potential to improve both efficiency and customer service simultaneously, they also have a strategic impact. The four perspectives on operations strategy A large part of Chapter 1 is taken up by explaining the ‘four perspectives’ on operations strategy. Although this is a good approach to understanding the various ways in which operations strategy can be analysed, it can be confusing to those who require a more prescriptive ‘recipe’ for putting an operations strategy together. The best way to think about these four perspectives is not as a guide to the ‘process’ of operations strategy (we will distinguish between content and process later), these issues are dealt with in the last three chapters. Rather, think about the four perspectives as exactly that – four different ways of looking at how operations strategy can contribute to the business. The four perspectives, as discussed in Chapter 1, are as follows: • Operation strategy is a top-down reflection of what the whole group or business wants to do • Operations strategy is a bottom-up activity where operations improvements cumulatively build strategy 203 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Operations strategy involves translating market requirements into operations decisions • Operations strategy involves exploiting the capabilities of operations resources in chosen markets Remember that the chapter does stress that none of these four perspectives alone gives a full picture of what operations strategy. However, they do explain the pressures which go to form the content of operations strategy. The next four sections in this chapter will treat each in turn. The top-down perspective – how should operations reflect overall strategy? The top-down perspectives on operations strategy views it as one of several functional strategies in a hierarchy of strategies. Not all enterprises will be sufficiently large to warrant a ‘corporate’ strategy, but any corporate or multidivisional group will need a corporate strategy to position itself in its global, economic, political and social environment. This means deciding what types of business the group wants to be in, what parts of the world it wants to operate in, how to allocate resources between its various businesses, and so on. This is the ‘corporate strategy’ of the group. Each business unit within the corporate group will also need to put together its own business strategy which sets out its individual mission and objectives. This ‘business strategy’ guides the business in relation to its customers, markets and competitors, and also the strategy of the corporate group of which it is a part. Also, within the business, each function will need a ‘functional strategy’ to shape what part each function should play in contributing to the strategic objectives of the business. The operations, marketing, product/service development and other functions will all need to consider how best they should organise themselves to support the business’s objectives. So, the top-down perspective on operations strategy is that it should take its place in this hierarchy of strategies. Its main influence, therefore, will be whatever the business sees as its strategic direction. The bottom-up perspective – how can operations strategy learn from operational experience? The top-down approach to operations strategy (or any strategy) is relatively easy to understand and is what most people think of as the way strategy should work. Yet there is plenty of evidence that, in practice, strategies are not always derived in such a clear and logical manner. Some strategy academics argue that very many strategic decisions are derived from day-to-day operational experience within the firm rather than any top-down vision of how the firm should be operating. The concept of an ‘emergent strategy’ is that strategy originates, not necessarily from the senior management in an organisation, but in the interaction of an organisation with its environment. In other words, a whole set of experiences within the firm prompt the formation of ideas an possible actions that eventually converge into a pattern of decision that reflect the way the organisations has learnt from its experiences. Of course, strategy can be formed through the deliberative actions of senior managers. Sometimes a decision is taken by senior management that goes on to become the implemented strategy of the organisation. But not every formal decision actually finishes up as an implemented strategy; sometimes they just kind of ‘fade way’ because they receive insufficient internal support in the organisation or become to be regarded as impractical. At other times, strategies emerge and may become formalised as explicit formal strategies later. Figure 1.5 illustrates this. 204 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The idea of bottom-up emergent strategies is particularly important for the operations function because operations have responsibility for so much of a firm’s day-to-day activities. Not all of course, other functions within the business such as marketing, finance, etc. also have resources that are devoted to day-to-day business. Yet, in many organisations the operations function (in its broadest sense) accounts for a very high proportion of its people, physical assets and investment. So, if an organisation aspires to capture the value from its on-going experience in creating and delivering service to customers, it must have an operations function that both learn from this experience and is capable of using that learning to contribute to strategy. The market requirements perspective – how do the requirements of the market influence operations strategy? The vast majority of practical models for operations strategy formulation take an ambiguously ‘market requirements’ perspective. That is, they start from an understanding of the markets that operation is intended to serve and then ask the relatively straightforward question, ‘what does the operation have to do in order to serve those markets well?’ This is a sensible starting point for assessing the appropriateness of any operations strategy. After all, if an organisation does not fulfil the needs of its market (or its broad social objectives in a not-for-profit organisation) it will not (or should not) survive in the long term. In this sense, the market requirements perspective is the most immediate and most important short-term perspective on operations strategy. The idea of operations strategy being driven by market requirements is sometimes called the ‘outside-in’ approach because it looks at the external market environment for an organisation and translates this into its internal implications. Yet, as the text points out, and as we reiterate in these notes, it is not the only perspective. In the longer term the other three perspectives also become important. But that does not invalidate the idea that, without satisfying markets, a business may not survive in the long term. The operations resource perspective – how can operations capabilities influence operations strategy? Some authorities argue that the way in which an organisation deploys or exploits its resources to create competences is a better predictor of sustainable competitive advantage than its choice of market position. Therefore, it is argued, operations strategy should concentrate on identifying and developing its ‘core’ competences which can then be exploited, perhaps in several markets. The concept of competence (the word comes from the Latin verb ‘competere’, meaning to be suitable) was first developed by psychologists to describe an individual’s ability to respond to 205 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual demands placed upon them by their environment. Now the extension of this concept encompasses entire organisations. If you want to understand the link between resources, processes and operations strategy decisions, look at the lighting company example in Chapter 1. It illustrates the nature of the ‘operations resource’ perspective. In the analysis of the example, Statement (a) is a summary of the company’s tangible resources – facilities and staff. Statement (b) identifies some of the intangible, largely knowledge-based, resources developed in the company. This leads on to (c) where the company recognises that these intangible resources are embedded in its routines. Brought together in Statement (d), these resources and processes give the company a unique set of competences which, given based on their experience, will be difficult for competitors to copy. However, to cultivate these competences the company, in Statement (g), identifies the decisions which will allow them to sustain their competitive advantage. The idea of intangible resources is very closely linked with the idea of competencies. To understand the value of the intangible resources that a company possesses, simply look to how they are valued by those who invest in it. The difference between the market value of a company and the value of its physical assets is, in part, explained by the company’s intangible assets. So, for example, a company’s reputation (or in a more managed sense, its brand) is often of immense importance to a firm’s success, yet may be difficult to define precisely. However, if a brand is closely identified with a distinguishing name, symbol, trademark or visual design, it may be valued in monetary terms, especially when a brand is sold independently of the operation’s (tangible) resources. Just because a resource is intangible does not necessarily mean it cannot be traded. Other intangible resources, although having real value to a firm, are less easy to trade. They are in that sense less tangible. Even the more tradable assets such as patents, copyrights, licensing agreements and brand names can be valued as part of a company’s capital in its financial accounts only under very strict conditions. Including such investments as research and development in a company’s assets is generally not allowed because of the difficulty in precisely associating future benefits from the investment. Those assets which are even less tangible, such as ‘knowledge’ or ‘intellectual capital’, cannot be formally counted at all. Commentary on the ‘Amazon, So what exactly is your core competence?’ example The example on the way Jeff Bezos (the founder of Amazon.com) now sees his vast company is a great example of how the underlying competencies of an organisation can come to define what it is. Admittedly, one of the major drivers of Amazon seeing itself as a technology provider has been the seasonality of its demand. Had Amazon not had to cope with this, it might never have been prompted to develop its other services. Nevertheless, it now does see itself as having acquired unique and difficult to replicate competencies that can be leveraged in other markets. Furthermore, these competencies have been developed within its operations function. Only by investing in and developing its information technology, fulfilment processes and skills over a long period of time could it have done that. Now it can take those competencies into other markets. This is an ideal example of strategy being formed ‘inside-out’. 206 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The appendix at the end of Chapter 1 reviews the idea of competencies and how it influences the resource-based view (RBV) of the firm. The RBV is particularly important in operations strategy because it highlights how many of a firm’s intangible resources are embedded in its routines. And the management of most of the value-adding processes and routines, as we noted earlier, is the prime task of operations management. The RBV also allows us to make the link between an organisation’s resources and processes and its capabilities. Example of the four perspectives on operations strategy – an e-learning company Top-down An entrepreneur owns several small companies, all of which are involved in some way in providing web-based solutions to businesses. Two companies are involved in web design. Two companies are involved in providing data analysis and data mining solutions to retail clients, and one company provides e-learning and employee development services to a range of large businesses, mainly in the banking, manufacturing and general service sectors. This e-learning company has decided to specialise in providing customised ‘blended learning’ packages. Blended learning is a careful combination of e-learning and ‘learning workshops’. The entrepreneur and the managing director of the e-learning company jointly decided to specialise in customised blended learning because they felt that it would provide a long-term profitable investment. The implication of this business strategy for the e-learning company is that its operations activities (the people in the company who create and deliver the customised packages for clients) need to be especially flexible because all clients believe themselves to have very specific and individual needs. It is also necessary to have wide network of subject experts and tutors on whom the company can call to help them in the preparation and presentation of the learning packages. What is important to understand is that different business objectives would probably result in a very different operations strategy. The role of operations is therefore largely one of implementing or ‘operationalising’ business strategy. Bottom-up So, the company has a business strategy that has positioned it as a provider of customised blended learning packages. These services have a higher margin than more routine e-learning packages. However, over time, the company’s operations and sales staff realise that two things are happening in the market. The first is that, although customers claim that they want totally customised packages, between 80 and 90 per cent of all customers are happy with a relatively standardised product with some elements customised to their own circumstances. Second, because competitors are starting to enter the market more aggressively, competition is becoming more significant and for the first time the company has to reduce its prices. Based on this experience the company’s operations staff start to develop broad ‘learning templates’ for different types of client. These broad templates define most of the product but allow for specially developed inserts to be ‘dropped in’ in order to provide a seemingly customised solution at lower cost. Eventually, this idea is formally adopted by the company’s senior management who put resources behind developing a number of templates that cover almost all of the company’s clients. 207 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Market requirements The company’s clients are almost all large companies, but the way in which these customers make the commissioning decision (the way they buy the e-learning company’s products) is changing. Increasingly, commissioning is done by human resource or ‘management development’ departments. Often, some part of the client organisation realises that it needs some development and asks the human resource department to commission development and training ‘interventions’. It also becomes clear that these HR departments are very poorly placed to make this kind of decision they need advice on how to handle their internal clients. Furthermore, requests often come at short notice (i.e. internally a department will say, ‘we want it yesterday’. In addition, more competitors are entering the market although, mostly, they are offering relatively standardised e-learning packages. Nevertheless, this is having an effect on prices by making customers a little more price sensitive. Because of these long-term trends in the market, the e-learning company decides that it must increasingly confine itself to the top end of the market specialising in high levels of customisation, expertise and high service levels and close client relationships. Given these market requirements, the implications for the e-learning company’s operations are that it must be able to provide a good diagnostic of each client’s needs, a high quality of package presentation and the flexibility to deal with different client’s needs and sometimes demanding lead times Operations resources From a market perspective the company’s operations must be able to provide insightful diagnostics of its client’s needs, a high quality of presentation, and flexibility in response to customer requests. The company’s operations staff do understand this and are constantly striving to achieve excellence in these areas. However, they also know that they should be building a set of operations-based capabilities that will be difficult for competitors to match. They were aware that they already had a set of tremendously valuable assets in their staff, the development software and web portal that they had developed, and their experience in designing multimedia e-learning packages. Furthermore, they had started to improve a number of their key processes such as the process that helps clients diagnose their development needs, the creative production process that designs and creates the learning package, and (increasingly importantly) the process of helping clients to implement and use the learning packages. While all these processes were satisfactory they felt that they needed to go further and establish a set of valueadded capabilities that were, to quote the company’s managing direction, ‘Better than anything on the market at the moment or is likely to be acquired by out competitors for some years to come’. As such, they decide to invest in acquiring a number of new skills. In particular, they use a system of supplying ‘guest developers’ who will actually be located within some of their larger customers for a period of time helping their client to understand their needs and implement the e-learning solutions. They also start to develop new web-based discussion boards and learning diagnostic processes (‘It is not just a matter of developing the software; it is also gaining the experience of how to make the software really add value for clients’). Finally, they also invest in extending their network of experts who can be called upon in the design process. Even though some of these ‘experts’ are not needed currently, the company wish to establish the relationships for potential future clients. Figure 1.6 illustrates this. 208 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual It is important to remind ourselves at this point that these four perspectives on operations strategy neither necessarily conflict nor are they alternative ways of formulating strategy. All four perspectives are valid and can be pursued simultaneously. As the text stresses, they simply represent alternative starting points for understanding operations strategy. What is operations strategy? – balancing market requirements with operations resources Operations strategy is the total pattern of decisions which shape the long-term capabilities of any type of operation and their contribution to overall strategy, through the reconciliation of market requirements with operations resources. So the chapter chooses to define operations strategy (or at least the way various operations strategy decisions are made) in terms of the reconciliation of two of these perspectives – market requirements and operations resources. Until relatively recently, the market requirements perspective was seen as the major, if not the only, driver of how operations strategy should be viewed. More recently it has become generally accepted that, by itself, this perspective is incomplete. There are very few organisations which can simply configure their operations resources to match market requirements quickly and effectively. Usually markets are capable of changing far faster than a company can reconfigure its resources. Therefore, at the very least, operations strategy must recognise the inertia and constraints represented by its physical facilities, people, technology, organisational structure and system. But the concept of operations resources is wider than this. All operations have a history and a set of experiences from which they have accumulated knowledge. This accumulated knowledge may even have formed itself into a set of competencies or capabilities which allow it to do certain things particularly well. Blindly reacting to (possibly short term) market demands, even if it is possible, would waste these capabilities. An important responsibility for the operations function is to understand its 209 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual own capabilities and attempt to build on these and develop them to a point where they provide a distinctive competitive advantage against competitors. This is what we mean by the operations resource perspective. But the dilemma is ‘does market position shape operations resources or vice versa?’ The text holds that, while both perspectives are important, and while the reconciliation of the two perspectives, in most cases market requirements dominate operations strategy decisions. All organisations have markets. Not all organisations have unique capabilities that are worth exploiting! Content and the process In some ways the distinction between the content and process of operations strategy (or strategy in general) is an artificial distinction as the text does point out. However, we use it in these notes (and it is used in the text) because at a simple level it allows us to distinguish between What you decide to do with in an operations strategy, and how you make that decision and make it work in practice. The first of these categories above is the content of operations strategy. That means the collection of decisions that together form the strategy. So ‘content’ refers to the detailed actions that will be taken to move an organisation in a particular direction. Process on the other hand, is concerned with sequence of steps that are taken in order to make content-type decisions. For example, consider an investment bank. Typical content decisions could include the following: • How big should each of our offices be in different parts of the world? • Should some offices specialise in particular areas of expertise or should each office be capable of doing everything? • Shall we do all our back-office processing ourselves or should we sub-contract it to another organisation? • If we do sub-contract, should we sub-contract everything or just the more routine processes? • If we do sub-contract, to whom should be give the contract? • Should we allow each office to develop its own IT platform, or should we impose some uniformity? • Should we update our back-office processing technology (IT systems) or should we wait for the next generation of technology? • Should we encourage each office to improve the effectiveness of their operations by providing development and training in various operations improvement approaches? • Should all back-office operations report to a global vice-president of operations, or should they report to the heads of the various regional or product markets? 210 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual By contrast, process-type decisions could be as follows: • Do we have any kind of formal operations strategy or do we let each regional office ‘do their own things’? • If we do have a formal operations strategy, should it be uniform throughout or global network? • Should senior managers in one region have any influence over decisions that need to be taken in another region? • Who should gather the information that will be used to inform operations strategy decisions? • Should we have ‘post-implementation’ reports that enable us to see how different operations strategy decisions have been implemented? • Do we encourage our various offices to adopt a particular approach to operations such as business process reengineering (BPR)? • What formal report procedures should each office have to go through in order to report on their progress? It is also worth noting that Slack and Lewis do point out that the distinction between content and process is not always clear. Content decisions, particularly around organisational structure, will inevitably affect the way strategies are formulated. Similarly, the way strategies are formulated is going to be influenced by the constraints that result from previous content decisions. Performance objectives Performance objectives are the dimensions of an operation’s performance, with which it will attempt to satisfy market requirements. They are Quality Speed Dependability Flexibility Cost And they will be considered further in the study guide to the next chapter. The important point is that it is through these five performance objectives that operations can contribute to competitiveness. It is also worth noting that, as the chapter points out, the relative importance of these performance objectives will be shaped by a combination of customers needs and competitors’ actions. Many authors on operations (or more frequently, ‘manufacturing’) strategy have defined their own set of performance objectives. No overall agreement exists on either the terminology to use when referring to these objectives or what they are. They are referred to variously as ‘performance criteria’, operations ‘strategic dimensions’, ‘performance dimensions’, ‘competitive 211 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual priorities’ or ‘strategic priorities’. Here, we will be using the term performance objectives. While there are differences between authors as to exactly what these performance dimensions are, the ones we use here include some commonly used categories. However, not all authors in this area use this particular set. For example, Hayes and Wheelwright at Harvard University do not use speed, seeing it as part of flexibility. Other authors include ‘innovation’ which we include as part of flexibility. To be honest it really does not matter. As we pointed out in the Management of Operations course, there are different aspects of quality, speed, dependability, flexibility and cost. Think of these five categories as clusters of issues, which at times will need separating out, depending on what we are trying to do with them. We use them here primarily because they were the terms which were used in the Management of Operations course. Decision areas Like many authors in this field, Chapter 1 identifies a number of ‘decision categories’ that, together, define how the operation is shaping its operations resources. Unlike other authors they seek to justify their decision categories by using ratio analysis. Two important points come from this ratio analysis. The first is that the operations function can influence return on assets (ROA) in more ways than keeping operational costs down (although clearly this is important). Operations also influences ROA through its impact on revenue generation, volume flexibility, imaginative and economical design of the process, and tight inventory management. The second point is that we can identify the four groups of operations strategy decision areas which are most associated with each part of this interconnecting pattern of ratios. The categories used in the text are as follows: • Capacity strategy • Supply network strategy • Process technology strategy • Development and Organisation strategy But, the boundaries between operations strategy decisions in these four areas are not clean. For example, decisions on capacity location are influenced by the choice of suppliers in the supply network; the extent of vertical integration is determined partly by the nature of the process technologies involved, the organisation structure of the operation is influenced by the size of operating locations, and so on. Furthermore, the exact nature of the decisions will depend on the nature of the organisation. However, this relatively straightforward categorisation allows the examination of each set of decisions in turn, even if it is necessary to remind ourselves continually of the interconnections between them. The operations strategy matrix Performance objectives and decision areas are clearly related to each other. There is a cause– effect relationship that works both ways depending on whether one takes a market requirements or operations resource perspective. So, from a market requirements perspective, the performance objectives that are required by the market will dictate what decisions are taken in each of the decision areas. From an operations resources perspective, the intrinsic capabilities of an operation that have been built-up over time by making a series of decisions in the various 212 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual decision areas will give an operation the ability to excess in certain performance objectives. This will then dictate how the company positions itself in its markets. The mechanism to try and understand the relationship between performance objectives and operations strategy decision areas is the ‘operations strategy matrix’. This is a relatively simple device that provides a ‘check list opportunity’ to articulate the relationship between each performance objective and each decision area. In this way, it brings the market requirement and operation resource perspective on operations strategy together. See Figure 1.7. 213 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 2 Operations performance Chapter aims • To illustrate how strategies emphasising different performance objectives are likely to need different operations strategy decisions • To illustrate how the relative priority of performance objectives differs in terms of whether competitive factors are order winners or qualifiers • To introduce the concept of some competitive factors as ‘delights’ • To show how the balance between the market requirement perspective of operations strategy and the operations resource capability perspective on operations strategy varies over time in response to external and internal stimuli • To examine the concept of trade-offs between performance objectives and introduce a simple categorisation of trade-offs • To introduce the idea of operations focus Introduction This chapter links three issues which are sometimes treated separately but are, in fact, very closely linked. The first idea is that operations strategy takes place in a dynamic environment where the aims of its stakeholders change over time, in particular as markets and resource capabilities change, the type of things operations strategy is called upon to do will also change. Second, at any point in this dynamic journey operations strategy has to accept that the things any operation can do are all interrelated. In the short term it cannot be exceptionally good at everything and may have to sacrifice performance in one area for excellence in another. Third, this idea of sacrificing one thing for great performance in another area can be taken to its logical conclusion by focusing or targeting operations on a very narrow set of tasks and objectives. What are ‘performance objectives’? The chapter starts with some reminders from the previous chapter regarding performance objectives. These are the main devices used to understand market requirements. They are the various aspects of performance that are used to express market requirements. However, ‘performance objectives’ are not the same as the various tools and classifications which 214 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual marketing professional use to understand markets. They are a set of broad performance measures which have some meaning to the operations function. Many of the concepts and frameworks used within the marketing function, although very effective at enabling marketing professionals to understand markets, have little meaning when brought within the operations function. Therefore, performance objectives are a ‘translation’ into operations-speak of a marketing professional’s view of the market. The five performance objectives used throughout the set text are • Quality • Speed • Dependability • Flexibility • Cost However, not everyone who writes on operations strategy uses this particular set. One of the best-known author teams, Hayes and Wheelwright of Harvard University, for example do not use speed, seeing it as part of flexibility. Other authorities include ‘innovation’ as a performance objective, while this chapter sees it as part of flexibility. It really does not matter. In fact, all the performance objectives, quality, speed, dependability, flexibility and cost, are really clusters of issues and measures. For example, ‘dependability’ could mean a proportion of services or products delivered late, average lateness, proportion delivered early, etc. It is best to think of each performance objective as a ‘bundle’ of more detailed factors which will need separating out. Sometimes these more detailed factors are called competitive factors. Figure 2.1 illustrates how competitive factors can be disaggregated from performance objectives. Think of performance objectives as providing a checklist defined in sufficiently broad terms to be applicable to any kind of business or operation. Perhaps the most important points implicit in the chapter is that the pursuit of different performance objectives implies different operations decisions. So, if it is particularly important for a process to exhibit high degrees of flexibility (say), it would be designed and run in a different way from another process where cost (say) is the dominant objective. This also applies at a more strategic level. In fact, it is even more important at a strategic level. Businesses that compete in different markets will emphasise different performance objectives which can only be 215 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual achieved by pursuing different policies and strategic decisions within the business. The following sections identify just some of the different types of decisions that are likely to be taken depending on whether the business competes primarily on quality, speed, dependability, flexibility or cost. Commentary on ‘A tale of two terminals’ example This cautionary tale explains one of the most embarrassing episodes in the history of a major airline. Look at the diagram in Figure 2.2 to understand how failures accumulated in the network of processes within Terminal 5 at Heathrow airport 216 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Quality-related strategies Businesses that emphasise the quality of their products or services are likely to pursue capacity strategy that avoids capacity shortages interfering with the need to devote resources to achieving high quality. It is also likely to stress the development of specialist knowledge within each part or site occupied by the business. Its supply network strategy may prefer to keep activities in house so as to maintain quality control. Suppliers are likely to be selected on the basis of their quality capability and relationships maintained through partnership and close coordination. Process technology must be secure, certain and well understood so as to reduce variability. Similarly, processes are likely to stress variability reduction, knowledge management and learning. This may suggest functionally based organisation structures that can develop and retain such knowledge. Speed-related strategies Speed related strategies will require surplus capacity so as to avoid bottlenecks where possible and sites close to sources of demand. Supply network strategy will emphasise the selection of suppliers who can respond quickly, understand their customers’ needs and communicate those needs quickly and effectively. If the business keeps inventory it may keep those downstream in the supply chain the faster to supply customers. Similarly, process technology, where possible, should ensure straight-through and fast throughput times which in turn may imply a degree of flexibility that does not inhibit fast response. New products and services must also be developed to emphasise fast time-to-market. This may include modular designs to avoid redesigning for every customers and market focussed organisational structures. 217 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Dependability related strategies Dependability related strategies will generally favour surplus capacity so as to guarantee supply to customers with any change in capacity levels ensuring the continuation of surplus capacity or (where possible) inventories to maintain supply. Multipurpose sites, each of which can perform a wide range of activities, could also help to ensure dependability of supply to customers. Supply network strategies may emphasise in-house or dual supply, partnership relationships, close coordination and (where possible) strategic inventories, all of which help to ensure supply to customers. Process technologies must themselves be reliable (as opposed to ‘state-of-the-art’ technology which is not as yet tried and tested). Maybe all smaller scale technologies operating in parallel so that failure in any one part of the process does not affect the whole process. New products and services must come to market dependably which implies project-based development teams. Maintenance processes to ensure reliable equipment will be needed and there is likely to be a heavy emphasis on identifying failure points through operational risk processes before they can disrupt supply. 218 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Flexibility related strategies Flexibility related strategies are also easier to achieve with surplus capacity (because of the uncertainty of demand at any time) and flexible or multipurpose sites that can respond to different types of demand. A wide network of suppliers, with a wide range of capabilities, is also likely to be an advantage especially if those suppliers are themselves flexible. Process technologies similarly must be flexible and may emphasise smaller scale technology. This is because many smaller pieces of technology may be able to offer a wider range of technological capability. Network-based organisation structures may also give the level of organisational flexibility required as will project-based design and development teams. Finally, if an organisation is to contain a wide range of capabilities, its staff must have a similarly wide range of capability and skills. 219 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Cost-related strategies Cost-related strategies are likely to want to try and utilise their capacity as much as possible. This implies that capacity must be kept at the level of demand or even below it to ensure high utilisation and therefore low unit costs. Furthermore, relatively few, large and specialised sites could exploit economies of scale and economies of specialisation. Supply network strategies may emphasise a continual searching for low cost supply using market-based mechanisms. It may even involve contracts with suppliers that emphasise year-on-year cost reductions. Where possible inventories should be minimised to reduce working capital requirements and off shoring opportunities to low cost locations may be explored. Automated technology may also help to reduce costs as can large-scale technologies that could bring more economies of scale. Improvement strategies will obviously emphasise lean philosophies of waste reduction. Standardisation of parts or processes and modularity of design will also help to reduce costs. 220 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Note… The explanations (and diagrams) used here are only indicative. The types of decisions described are not comprehensive, nor are they universal. They simply serve to illustrate the contingent nature of operations strategy. In other words, what you do strategically depends on what you want to achieve. Order-winners and qualifiers and ‘delights’ The chapter also deals with the distinction between order-winners and qualifiers, one of the most important issues in operations strategy. Order-winners are those aspects of performance that, when improved, will significantly and directly improve the competitive position of the business. Qualifiers are those aspects of performance that, when they get worse, may drastically impair competitive performance of the business, but where improvement will not necessarily improve competitive performance. Qualifiers may also be called ‘dial tone factors’ (just like the dial tone on a telephone, one only notices when it is not there). The concept of ‘delights’ is an intriguing one. Delights both add value in some way for customers and yet are unexpected until they are introduced to the customer. The implication of this is that no competitor is currently offering that competitive factor, at least not to the same level. So, according to this definition, delights do not come from anything other than relatively novel (or novel levels of) competitive factors. 221 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Operations strategy changes over time The chapter draws extensively on the example of Volkswagen (VW) Motor Company and traces its history from its foundation up to the present day. In doing so, it shows how the balance between operations resources and market requirements has changed over time. Interestingly, the one time when the company was having major difficulties in understanding it own strategy was the time when both operations resources and market requirements were themselves confused. The chapter also revisits the idea of the ‘emergent strategy’ as being important when considering the dynamics of operations strategy. Do not underestimate this point. Remember… ‘the concept of emergent strategies in an important one in operations strategy. Emergent strategies often emerge from the organisational resource which are the direct responsibility of operation….’ At different points in its history VW has adopted strategies that have emerged as a result of its experiences. Commentary on ‘VW – The first 70 years’ example ‘Volkswagen has acquired symbolic stature for whole generations of people. Of all the motor vehicles that have been produced, the Beetle, the VW Bus, the Golf and the New Beetle are practically unparalleled in the extent of their identification with entire epochs of social history’ – Volkswagen Kommunikation. The story of VW over such an extended period really does illustrate the dynamics of operations strategies. They do not, and should not, stay constant over time. They will shift and adapt to internal and external stimuli in a way that makes full sense only in retrospect. The reconciliation between market requirements and operations resource capability is a response to these stimuli – an attempt to maintain competitiveness notwithstanding the pressures of environment and organisational circumstance. Reconciliation is what you do to make things fit. In fact, notice how, in Slack and Lewis’ Figure 2.9, the reconciliation process is described in terms of the firm’s product offerings. Often this is the most revealing way of illustrating reconciliation, because a firm’s products or services are the outward manifestation of how it attempts to reconcile what it believes the market requires with what it is capable of producing. Embedded in the product or service is the package of performance characteristics which the firm is making available to the market. Within this package of performance characteristics are also to be found the prioritisation and trade-offs inherent within the firm’s decision-making processes and behaviour. (We shall deal with trade-offs more fully later in the chapter.) Note also that the process of strategic decision-making is not always neat or necessarily even well thought out. At times Volkswagen, like any other company, were reacting to events in a manner which was more painful to them than if they had taken similar decisions earlier, before they became crises. The company’s struggle to reduce its cost base during the 1990s is an example of this. At other times the company seemed to move towards a strategic position not so much through planning as through a slowly emerging consensus. These strategies are what were called in Chapter 1 emergent strategies. The concept of emergent strategies is an important one in operations strategy because they often emerge from the organisational resources which are the direct responsibility of operations. For example, the move to modify the ‘common platform’ strategy could be seen as an emergent strategy. The following is a press statement from VW explaining the move. 222 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual VW save up to 1,000 dm per car in new production strategy – Piech 06 November 2000 WOLFSBURG, Germany Volkswagen AG is about to overhaul its ‘platform sharing’ strategy, with a system that could save up to 1,000 dm per car, Ferdinand Piech said in an interview in the Wall Street Journal Europe. No longer will the company focus its savings strategy on developing cars of similar sizes that sit on the same platform. Rather, VW is now aiming to develop ‘joint production systems’ that could lead to major components being shared by a wide range of models and brands, he said. Piech said that is some cases he will be able to save up to 1,000 dm in production costs per car under the new program as the company achieves greater economies of scale. The strategy will also help underscore differences within VW’s wide-ranging brand portfolio, he said. All told, he envisions VW basing models on eleven joint-production systems, which will be implemented through 2005. ‘In the future we are going to have 11 module systems instead of four platforms’, Piech said. He also said the company will achieve a return-on-capital target of 9 pct to 11 pct by next year, possibly even this year. VW needs to expand its profit base, he added. Now, almost all of its profit is generated by new car sales and its parts business. Several years down the road, however, the company hopes to cleave its profit base into thirds – new cars, financial services and vehicle servicing. A number of points emerged from this move. In the balance between operations efficiency (which is enhanced by shared platforms) and effective market positioning (through the company’s brand strategy), the shared platform strategy probably leaned too much in the direction of exploiting the efficiencies of platform sharing at the expense of brand values. Much of the press speculation during 2001 concerned the damage to VW’s premium brands (such as Audi). Customers were, so the press said, reluctant to pay a premium for the Audi brand when a very similar car (with the same platform) can be bought less expensively with a Skoda badge. Cost reduction objective remains, but the way of achieving it shifts from a design-based solution (shared platforms) to one based on the company’s broad operations capability (common module designs and production systems). The operations function is still seen as the main driver of the company’s strategic direction. This manufacturing company sees its future as a balanced service and manufacturing company. 223 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Trade-offs A trade-off implies that there is a relationship between simultaneously desirable operations objectives. Furthermore, it implies that at least the broad form of this relationship is known. So, for example, ‘We know that our costs will increase if we offer more choices of colour to our customers, and costs will increase even more dramatically if we also offer a choice of size’. This statement identifies that costs will increase as variety increases and, furthermore, that costs will increase more rapidly for certain types of variety extension. The issue of trade-offs has been one of the most closely fought debates in operations strategy. Broadly speaking, there are three schools of thought regarding trade-offs. The original school of thought derives from Skinner who was the first to point out that trade-offs were an important issue in operations strategy. He emphasised the point that trade-offs should be managed to reflect the company’s overall strategy. In other words, achieving the right balance or positioning between various performance objectives is fundamental to operations strategy. The second school of thought was very much opposed to this idea. It emerged in the early 1980s under the influence of Japanese manufacturing principles and the concept of continuous improvement. Put simply, it claimed that trade-offs were largely imagined, that the main objective of operations management was to be good at everything. Merely accepting that one aspect of performance must deteriorate if another is to be improved was, they claimed, at best unimaginative and at worst irresponsible. The final (and now largely accepted) school of thought is that yes, tradeoffs do exist, but over time they can be overcome. This is the approach taken in the chapter. Figure 2.8 indicates these three schools of thought using the kind of trade-off diagrams explained in the chapter. A typology of trade-offs Trade-offs are found in all types of operation and at all levels. Because trade-offs describe the relationships between different aspects of operations performance, any pair of performance measures potentially constitute a trade-off. And, since they may represent a legitimate target for operations improvement, it is important to be able to identify an operation’s trade-off 224 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual relationships. Identifying trade-offs is best done by looking for them within specific categories. This requires a typology of trade-offs. The list of generic performance objectives (quality, speed, dependability, flexibility and cost) provides a good starting point. For convenience we divide these five generic performance objectives between, on one hand, the four which can be taken to constitute the service which an operation delivers to its customers, and, on the other hand, the cost of providing the service. In addition, both cost and service can be influenced by the capital expenditure the operation commits to its facilities, and the level of working capital (usually in the form of inventories) the operation works with. Trade-offs can occur between any pair of from these four categories as shown in Figure 2.9. The following example illustrated these trade-offs: Food Co. is a manufacturer of confectionery products. Their product range can be divided into three groups. Chocolate bars account for around 5 per cent of total output by volume and exhibit relatively low seasonality. Assortments account for around 75 per cent of total output by volume and is seasonal with its two peak periods for sales in April and December (Easter and Christmas) having sales of 160 per cent and 210 per cent of the low season average (August), respectively. Chocolate novelties account for around 20 per cent of output and are highly seasonal, with sales limited to the Easter and Christmas periods. The manufacturing processes for the first and last product groups are effectively single-stage processes with manufacturing and wrapping fully integrated. Assortments are manufactured in two stages, the manufacture of the individual chocolates, which are then stored prior to assembly in a variety of pack types. The company has recently invested in some automatic packing equipment for its chocolate bar products. This has considerably reduced labors costs for this product. However, the company still had to produce different products for different market which added to costs. ‘The problem is that tastes vary between different markets. We have to use a different recipe for the chocolate we sell to Northern Europe as opposed to Southern Europe for example. Changing recipes adds to the complexity of scheduling and generally reduces the utilisation of equipment’. The company was also considering investing in flexible packing equipment for its assortments products. Currently, individual chocolates are automatically wrapped and automatically packed into boxes using relatively old equipment. Investing in newer equipment would allow for a wider variety of shapes and sizes of boxes. ‘At the moment we really do have to restrict our 225 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual marketing department from using novel pack shapes which could very well increase sales. They have to restrict their designs to a narrow range of basic shapes. This new equipment would allow us to extend our use of special promotions and other sales promotion ideas’. The other problem in producing assortments was how to cope with seasonal sales variations. Currently, the company produced more or less evenly throughout the year, producing for finished goods inventory during the low periods and depleting the inventory during the high demand periods. This saved the disruption and cost of changing production levels every month but increased the working capital tied up in inventories over the year. The main problem with the chocolate novelties products also came from seasonality. Though in this case the seasonality was much greater and demand much more difficult to forecast. Building up a large inventory before the heavy demand period allowed the company to cope with heavier than expected demand but also increased the working capital and obsolescence costs. One possible solution being considered was to invest in more physical capacity which would allow production levels to be flexed at short notice in line with fluctuations in demand. Trade-off analysis for Food Co. Analysing the trade-offs for Food Co. is more complex than it was for Call Co. This is because an extra performance dimension needs to be included, namely working capital. Figure 2.10 illustrates six of the trade-offs which Food Co. has to deal with. For chocolate bar production there are two main issues. The first concerns the chocolate recipe. Using many recipes enables different products to match regional tastes but increases manufacturing costs. The second concerns the recently installed automatic packing equipment. This required capital expenditure but has saved on manufacturing costs. The investment being considered for assortment packing, by contrast, aims to increase flexibility. Thus, the ability to produce a wider variety of products may be obtained at the cost of extra capital investment. Investment of another type is involved in scheduling production levels for assortments. Keeping manufacturing levels constant reduces manufacturing costs but at the expense of working capital investment in finished goods inventory levels. Similar trade-offs affect the highly seasonal novelty products. Building up investment in pre-season inventories, although costly in working capital terms, does allow the company to respond to unexpected demand. However, investing in inventory would be unnecessary if the company had sufficient capacity for novelty manufacture to respond to demand as it occurred. This however would necessitate investment in new capacity. 226 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Trade-offs in reconciliation The idea of reconciliation can be described in terms of two elements in managing trade-offs within the operation. These are • Repositioning the balance between the different aspects of the trade-off and • Overcoming the trade-off through improvement Reconciliation as repositioning trade-offs While not the only way to manage trade-offs, repositioning clearly has a role in reconciling market requirements with operations resources. In fact at one time it was regarded as the only way of achieving reconciliation. An operation’s relative achievement in each dimension of performance, it was argued, should be driven by the requirements of its markets. This would involve emphasising some aspects of performance and (inevitably) sacrificing others. Even when it was considered to be the sole route to reconciliation, repositioning the relative performance balance through trade-offs was never regarded as straightforward. Operations are bundles of complex organisational and technological systems. They cannot be simply repositioned by adjusting a set of simple controls. Two factors in particular complicate the repositioning process • There is a ‘friction cost’ of changing relative performance levels. • The complexity of trade-off interrelationships can set in chain a set of other trade-offs. As an example take a frozen food manufacturer. One of the trade-offs which its operations will have to manage is that between inventory levels of finished product and the ability to respond to unexpected demand, therefore giving better service to customers. The company has to choose between good customer service or good (i.e. low) working capital. In practice, changing the balance between these two dimensions of performance will itself involve some extra effort (and therefore cost) in order to decide exactly which products are to have their stock levels increased or reduced. More important, there is a degree of risk involved in making this choice. Get the decision wrong and both dimensions of performance could get worse. For example, suppose working capital is to be increased to give better customer service by investing in higher inventory levels in selected product lines. If the wrong products are chosen then working capital will increase while customer service levels could get worse. The company could finish up with high stock levels of the wrong products while failing to satisfy its customers in delivering the right ones. To some extent, changing the position of a trade-off involves moving to less wellknown operating conditions. This not only means extra planning effort but also extra risk. Factoring the extra planning with the increased risk together constitutes the friction cost of repositioning. Even when the trade-off between working capital and customer service is executed well, in terms of making the correct stocking decisions, other relationships may complicate the issue. For example, increased inventory may give a better chance of responding to customer requirements, but it will also increase the average time products spend in finished goods storage. Given that this product has a limited life, quality may be compromised by extra time in storage and the ‘shelf life’ available to the customer may be reduced. So by repositioning the trade-off (between service level and working capital) in favour of service level, another trade-off (between service level on one hand and product quality and life on the other) has been affected. 227 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Repositioning trade-offs is rarely an isolated decision. In practice, attention cannot simply be focused on one, easily bounded, relationship. The interrelationships between trade-offs need to be considered. It is a mistake to dismiss repositioning as merely working within the existing constraints of an operation. Repositioning can result in sometimes substantial improvements in operations performance. The British Airways’ first class seat redesign example shows that changing the balance between aspects of performance can result in superior performance overall. Reconciliation as overcoming trade-offs Repositioning trade-offs was described earlier as moving the balance between dimensions of performance along an operation’s ‘natural frontier’ (from X to Y in Figure 2.11). Using repositioning to achieve reconciliation between market requirements and operations resources is fine if market requirements lie within the natural frontier of the operation, as in area P in Figure 2.11. However, if market requirements are such that performance levels must fall within area Q then the only way to achieve reconciliation is either to abandon the target market which requires this combination of performance, or alternatively to extend the natural frontier of the operation so that its performance is improved to the extent that it can now satisfy market requirements – position Z in Figure 2.11. For example, in many financial services firms that offer a ‘direct call’ service, one trade-off is that between the utilisation of staff in call centres and the time taken to respond to customer calls. If the company’s human resource policies allow for a ‘capacity cushion’ of staff to be on duty they may not always be fully employed and therefore labour cost per transaction would be relatively high. However, because of the relative over-supply of staff, customers would only rarely have to wait more than a few rings before their call was answered. The company could therefore gain more business. Transaction costs may be high but so would be revenue. A repositioning approach would involve deciding on the balance between utilisation of staff (therefore transaction cost) and response time (therefore revenue) that would maximise profitability. However, an improvement approach would seek to either • Improve both dimensions of performance or • Improve one dimension of performance while preventing or limiting any deterioration in the other. 228 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Both of these options would, in effect, push back the natural frontier of the operation’s capabilities. For example, a financial services company may decide to redesign their working time practices. Their new approach involves paying a small premium to staff who live within a 20-minute journey time of their call centre. This premium would allow them to be ‘on call’ for certain periods when demand was relatively unpredictable. This allows each call centre to bring in staff at very short notice if their predictive systems indicate a higher than expected level of demand building up. Making such a change could materially affect the trade-off relationship between staff costs and customer response time by allowing better response time with only marginal increases in staff costs. The trade-off is still there, of course. Even with this new working time policy, staff utilisation and response time will trade off against each other. But now the trade-off is at a higher level – the operation’s natural frontier has been pushed back. Commentary on the ‘Flat beds trade off utilisation for comfort’ example The trade-offs involved in the installation of flat bed seats at British Airways (and subsequently many other airlines) is a good example of how different types of trade-off interact with each other. Figure 2.12 illustrates this. In this case, because the service offered is largely intangible, working capital is not a direct issue. Nevertheless, the other three categories of capital expenditure, cost and service are all affected. So increased capital expenditure on seats reduces the space utilisation of the cabin but also increases the perceived level of service by customers (they have more space and are more comfortable). So, service increases but space utilisation decreases. This translates as revenue increases but so do costs. In this case, the repositioning between service and cost resulted in higher levels of profitability because customers were willing to pay far more for the increase in service than the airline’s costs had increased. 229 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Operations focus The idea of targeting operations or parts of operations on a relatively narrow set of tasks or markets is not a new one. It was first written about in the 1960s and 1970s and pre-dates that in practice. Yet it is still one of the most important ‘solutions’ to managing the complexity present in most operations. Put simply, focused operations are given a narrow set of objectives, technologies, products or services, markets, or activities on which to concentrate. A focused operation is one which does not have to do everything. There are a number of advantages to focusing operations. The overall managerial targets for operations management can be made simple and clear. For example, ‘We will protect you from the variations in the market but you must keep costs to a very minimum’ or ‘No customer must ever be turned away, you must customise services to meet their individual needs, even if this means increasing our costs.’ Resources appropriate for those narrower set of objectives can be allocated to this focused operation. For example, if cost is the main objective then high volume, low variable cost technology could be used. If customisation is particularly important then more flexible technology could be used. The same applies to people and systems. Focused operations can take a more appropriate improvement trajectory. For example the operations which concentrate on cost can become particularly experienced in shaving every cent off operations costs, whereas those specialising in customisation can develop particular skills of understanding and interpreting customers’ needs into the delivered service. 230 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Comment on the ‘Ryanair’ example Slack and Lewis use Ryanair, the low cost airlines as an example of operations that have placed themselves at an extreme trade-off position, by sacrificing service functionality for low cast. They also credit Southwest Airlines as the original, and still the best of these focused airlines. Southwest Airlines is the only airline that has been consistently profitable every year for over thirty year. It is also now one of the largest airlines in the world by value. Yet back in 1971 it was upstart three-jet airline operating out off Dallas, Texas (still its headquarters). The strategy of the company has been consistent since it was founded, to get its passengers to their destinations when they want to get there, on time, at the lowest possible fares, and make sure that they have a good time doing it. Its success in achieving this is down to clever management, a relaxed and employee-centred corporate style, and, what was then a unique way of organising its operations. For over 30 years it has introduced a series of cost saving innovations. Unlike most airlines it provided simple snacks (originally only peanuts) instead of full meals. This not only reduced costs but also reduced turn round time at airports. Because there are no meals there is less mess to clear up and also less time is needed to prepare the galley and load up the aircraft with supplies. Passengers were sold tickets without a seat allocation (simpler and faster) and expected to seat themselves (faster). Originally, boarding passes were plastic and reusable and the company was one of the first to use electronic tickets. It was also early in its adoption of the internet to sell tickets directly to passengers. Although most airlines at the time used a range of different aircraft for different purposes, Southwest has consistently stuck with Boeing 737s since it started. This significantly reduces maintenance costs, reduces the number of spare parts needed and makes it easier for pilots to fly any aircraft. Southwest’s employee involvement practices are designed to empower employees to take responsibility for maintaining high efficiency and high quality of service with profit sharing plans for almost all employees and innovative stock options plans for its pilots. The result has been what some claim to be the most productive work force in the airline industry. Comment on the ‘Burning your bridges (or boats)’ example An attractive operations strategy for many businesses is to set-up ‘focused operations’ that concentrate on one activity or part of a market. The example ‘Burning your bridges (or boats)’ demonstrates one of the advantages of such an arrangement, but also highlights one of the risks that accompany these benefits. Put simply, an operation with a high degree of focus must make a success of its business or fold. There is nowhere else to go. This is where the ‘burning your bridges’ analogy comes in. Army 1 that has deliberately destroyed its own means of retreat has (presumably) two options: (a) fight or (b) die. By contrast, Army 2 has two different options: (a) fight or (b) run away. In effect, Army 1 has reduced the ‘symmetry’ of its decision options. This is what, at its extreme, operations focus does. By setting up a separate operation focused exclusively on one task or part of the market, one is taking away the option of compromise or retreat because that focused operation is incapable of doing anything but the activities for which it was designed. 231 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 3 Substitutes for strategy Chapter aims This chapter is a little different from the other chapters in the book. It deals with a number of ‘new’ approaches to the management of operations that are often seen as operations strategies, but are not actually strategies in themselves. Four of the more important ‘new’ approaches are treated in the chapter, namely, Total Quality Management, lean operations, Business Process Reengineering and Six Sigma. They all need to be understood (particularly the similarities and differences between them) if they are going to help with strategy or strategic implementation. Of course, none of these approaches can transform an organisation over night, but what really matters in the long run is how these approaches help an organisation to learn from its experiences and build operations capabilities. The chapter aims to: • Examine the background and elements of Total Quality Management. • Examine the background and elements of lean operations. • Examine the background and elements of Business Process Reengineering. • Examine the background and elements of Six Sigma. • Examine how these approaches can contribute to operations strategy. The list is not exhaustive The chapter’s ‘new approaches to operations improvement’ is by no means exhaustive. Almost all academics and consultants in this area will have their own prioritised list of improvement approaches. Other candidates that could have been added to their list include Total Productive Maintenance (TPM), Quality Function Deployment (QFD), Zero Defects, Cycle Process Reduction (CPR), the Work-out Approach, Quality Circles, Value Engineering and so on. Nor is there is much hard evidence as to the extent to which these approaches actually give concrete results in terms of performance improvement. Also, the success of any or all of these new approaches seems to be very much context-dependent. 232 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual One of the earliest investigations is one of the most interesting.1 The data from the study, when analysed, supported the idea that TQM does provide economic value to a firm. Also, firms that had adopted TQM for long periods reported more satisfaction with the approach than those with less experience. Yet long-term TQM firms did not seem to have a significantly higher performance level than short-term TQM firms. This may be because long-term TQM firms had more chance to master the core TQM techniques and were therefore more confident in their use, even if the benefits were not particularly evident. More broadly, the conclusions of the survey were reported as follows. 'The findings support the conclusion that TQM can produce economic value to the firm, but that it has not done so for all TQM adopters. TQM’s success appears to depend critically on executive commitment, open organisation and employee empowerment, and less upon such TQM staples as benchmarking, training, flexible manufacturing, process improvement and improved measurement. Although firms may find these tools indispensable to a fully integrated TQM initiative, they apparently do not produce performance advantage in the absence of the intangibles. This result is consistent with the resource-based notion of complementary resources, and suggests that, rather than merely imitating TQM procedures, firms should focus their efforts on creating a culture within which those procedures can thrive.' In other words, the tools and techniques of TQM are necessary and valuable, but they depend critically on other intangible and cultural factors. The study goes on to suggest that, ‘Although the intangibles were universally important to TQM’s success, other factors were contextdependent.’ In other words, an organisation may or may not master the detailed tools and techniques of TQM, but even if it does make a perfectly sound set of decisions on adopting exactly the right techniques, it is unlikely to be successful unless it gets the intangibles right. And this probably applies to all the ‘new’ approaches discussed in this chapter. Getting the details right is a necessary (and important) but not sufficient condition for successfully adopting any of these approaches. Nevertheless, as the chapter puts it…‘Before anyone can judge whether any of these new approaches is right for them, they must understand what they are, their underlying philosophy and how they differ from each other.’ The four approaches discussed are as follows: • Total Quality Management • Lean operations • Business Process Reengineering • Six-Sigma Total Quality Management (TQM) TQM is, ‘an effective system for integrating the quality development, quality maintenance and quality improvement efforts of the various groups in an organisation so as to enable production and service at the most economical levels which allow for full customer satisfaction’2. TQM was one of the earliest management ‘fashions’ that peaked in the late 80s and early 90s. TQM now 1 Powell, T.C.

(1986) Total Quality Control, New York: McGraw Hill. 233 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual seems a little outdated. Yet, this does not mean that the ideas behind TQM are no longer worth studying or that TQM is no longer influential. In fact, some of its principles have been ‘absorbed’ into many organisations’ improvement philosophies. This is partly because TQM was never just about 'quality management as such'. It was always about more than simply assuring product or service quality. It would be more accurate to view TQM as being a way of doing business. Its principles cover many different aspects of management from managing people and business processes to aiming for complete customer satisfaction at every stage in every process. The origins of TQM All of the approaches covered in the chapter are the subject of some debate as to what their main principles are, what the true definition of the approach is and so on. No more so than TQM. Perhaps that is why almost all descriptions of TQM start by identifying the authorities who, through their work, contributed to developing the idea. Unfortunately, these individuals came to be known as TQM ‘gurus’. Table 3.1 identifies some of these ‘gurus’ together with the strengths and weaknesses of their particular perspective on TQM. Table 3.1 Some relative strengths and weaknesses of some of the quality gurus Quality ‘guru’ Strengths of approach Armand Feigenbaum was a doctoral student at the Massachusetts Institute of Technology in the 1950s when he completed the first edition of his book Total Quality Control. He defines TQM as: ‘an effective system for integrating the quality development, quality maintenance and quality improvement efforts of the various groups in an organisation so as to enable production and service at the most economical levels which allow for full customer satisfaction’.

Despite his early writings in America, it was the Japanese who first made the concept work on a wide scale and subsequently popularised the approach and the term ‘TQM’. W. Edwards Deming, considered in Japan to be the father of quality control, asserted that quality starts with top management and is a strategic activity.3 It is claimed that much of the success in terms of quality in Japanese industry was the result of his lectures to Japanese Provides a systematic and functional logic which identifies stages in quality improvement Stresses that management comes before 234 © Nigel Slack and Michael Lewis 2012 Action plan and methodological principles are sometimes vague The approach to leadership and motivation s seen by some as idiosyncratic Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual companies in the 1950s. Deming’s basic philosophy is that quality and productivity increase as ‘process variability’ (the unpredictability of the process) decreases. In his 14 points for quality improvement, he emphasises the need for statistical control methods, participation, education, openness and purposeful improvement: Leadership and motivation Does not treat situations are recognised as important which are political or coercive Emphasises role of statistical and quantitative Recognises the different methods contexts of Japan and North America Joseph M. Juran tried to get organisations to move away from the traditional view of quality as ‘conformance to specification’ to a more user-based approach, for which he coined the phrase ‘fitness for use’. He pointed out that a dangerous product could conform to specification but would not be fit to use. Juran was concerned about management responsibility for quality, but he was also concerned about the impact of individual workers and involved himself with the motivation and involvement of the workforce in quality improvement activities.5 Emphasises the need to move away from quality hype and slogans Kaoru Ishikawa has been credited with originating quality circles and cause-and-effect diagrams. Ishikawa claimed that there had been a period of over-emphasis on statistical quality control (in Japan), and as a result people disliked quality control. They saw it as something unpleasant because they were given complex and difficult tools rather than simple ones. Furthermore, the resulting standardisation of products and processes and the creation of rigid specification of standards not only made change difficult but made people feel bound by regulations. Ishikawa saw worker participation as the key to the successful implementation of TQM. Quality circles, he believed, were an important vehicle to achieve this.

Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual optimisation of product design combined with statistical methods of quality control. He encouraged interactive team meetings between workers and managers to criticise and develop product design. Taguchi’s definition of quality uses the concept of the loss that is imparted by the product or service to society from the time it is created. His quality loss function includes such factors as warranty costs, customer complaints and loss of customer goodwill.7 Recognises quality as a societal issue as well as an organisational one. Phillip B. Crosby is best known for his work on the cost of quality. He suggested that many organisations do not know how much they spend on quality, either in putting it right or getting it wrong. He claimed that organisations that have measured their costs say that they equate them to about 30 per cent of sales (others suggest a smaller figure of around 10 per cent). Crosby tried to highlight the costs and benefits of implementing quality programmes through his book Quality is Free in which he provided a zero defects programme. This is summarised in his absolutes of quality management. Provides clear methods that Seen by some as implying are easy to follow. that workers are to blame for quality problems.

Quality is seen as primarily controlled by specialists rather than managers and workers. Regarded as generally weak on motivation and people management issues. Insufficient stress given to statistical methods. While some authorities see TQM’s dependence on the work of quality ‘gurus’ as positive, other see it as a major weakness in the whole concept. Although sincere in their beliefs, many TQM gurus were consultants who made their living out of selling their own ideas. Under those circumstances there is a clear conflict of interest between a dispassionate and evidence-driven approach to examining the behaviour of organisations and the need to develop a set of simple prescriptions that managers could easily understand and implement. Moreover, by reducing quality management to a simple list of good practice ideas, it ignores the often hugely important, differences in organisation context. TQM puts the customer at the centre of improvement An important element in TQM is the idea that all businesses have many types of customers, both external and internal. And the relationships between internal customers and suppliers are important because it directly influences the relationship with external customers. In fact, TQM focuses strongly on the importance of the relationship between customers (internal and external) and supplier. Networks of process are known as the 'quality chains'. They can fail at any point by one person or one piece of equipment not meeting the requirements of the customer. Not fulfilling customer requirements in any part of the quality chain will multiply failure by creating problems elsewhere, which in turn leads to yet more failure and problems. 236 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual TQM’s emphasis on the ability to meet customers’ (external and internal) requirements has led to the popularising of a series of questions. The idea is that all process or operations managers should be able to identify and understand their customers and suppliers. Table 3.2 illustrates a typical set of questions. Table 3.2 Typical customer and supplier analysis questions How well do I relate to and understand my customers? How well do I relate to and understand my suppliers? • Who are my customers? • Who are my internal suppliers? • What are their actual needs and expectations? • What are my true needs and expectations? • What is my ability to meet their needs and expectations? • Do I communicate my needs and expectations effectively to my suppliers? • Do I have the capability to meet their needs and expectations? • Do my suppliers have the capability to meet my needs and expectations? • If not, what must I do to improve this capability? • How do I communicate effectively any changes in my needs and expectations? • Do I always meet their needs and expectations? • If not, what prevents this from happening when the capability exists? • How do I detect changes in their needs and expectations? Don’t dismiss these questions or the ‘questioning’ approach. At first glance it may seem both superficial and certainly not strategic. Yet remember that the internal customer concept that was originated in the TQM philosophy does point out that an important part of strategic capability does derive from operational practice. Or, as TQM proponents would put it, 'How can you hope to satisfy external markets if you can’t even fulfil internal customer requirements?' Kaizen or continuous improvement An enduring legacy of TQM is the idea of continuous improvement (CI), also known by its Japanese (more or less) equivalent term ‘kaizen’. Both terms refer to the idea of constantly introducing small incremental changes in a business in order to improve performance. Underlying this approach is the assumption that employees are the best people to identify improvement opportunities because they see the details of what really happens within processes all the time. The implication is that a firm that uses this approach therefore has to have a culture that encourages and rewards employees for their contribution to the process. Key features of Kaizen include the following • Improvement is based on many, small changes. • Since ideas come from staff, they are likely to be easier to implement. 237 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Small improvements are less likely to require major capital investment than major process changes • All staff see their jobs as including seeking ways to improve their processes. • An emphasis on developing a culture of trust throughout the organisation. The 'Business Excellence’ model from the EFQM The third aspect of TQM that has endured is not so much a ‘legacy’ as a development of many of the themes that made TQM so popular. These themes are included in Figure 3.2 in Chapter 3. It has been used widely, especially throughout Europe, as a model (or rather a framework) for assessing quality and improvement. A number of research studies have investigated the correlation between the adoption of holistic Models, such as the EFQM Excellence Model, and improved organisational results. The majority of such studies show a positive linkage.3 The EFQM describes its model as follows: 'Regardless of sector, size, structure or maturity, to be successful, organisations need to establish an appropriate management framework. The EFQM Excellence Model was introduced at the beginning of 1992 as the framework for assessing organisations for the European Quality Award. It is now the most widely used organisational framework in Europe and it has become the basis for the majority of national and regional Quality Awards… [It]….a practical tool that can be used in a number of different ways: • As a tool for Self-Assessment. • As a way to Benchmark with other organisations. • As a guide to identify areas for Improvement. • As the basis for a common Vocabulary and a way of thinking. • As a Structure for the organisation’s management system. The EFQM Excellence Model is a non-prescriptive framework based on 9 criteria. Five of these are “Enablers” and four are “Results”. The “Enabler” criteria cover what an organisation does. The “Results” criteria cover what an organisation achieves. “Results” are caused by “Enablers” and “Enablers” are improved using feedback from “Results”. EFQM also believes that the process of Self-Assessment is a catalyst for driving business improvement. Its definition of Self-Assessment is as follows: Self-Assessment is a comprehensive, systematic and regular review by an organisation of its activities and results referenced against the EFQM Excellence Model. The Self-Assessment process allows the organisation to discern clearly its strengths and areas in which improvements can be made and culminates in planned improvement actions that are then monitored for progress. 3 K.

March 1996, pp. 415–436 238 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Some of the benefits of using the model for self-assessment include: • Providing a structured approach to identifying and assessing organisational strengths and weaknesses. • Improving the process of how plans are developed. • Creating a common language and conceptual framework for improvement. • Educating staff on the factors that contribute to operations performance. • Integrating possible disparate improvement initiatives within an organisation Lean operations The principles of lean operations are counterintuitive, particularly to those who have been brought up in what was the conventional wisdom of operations management that was obtained during the 1970s (and still is orthodoxy in some manufacturing and many service industries). It is also partly because the many ideas and principles that go to make up lean are interconnected. The chapter describes how customer-centric pull triggers synchronous flow that leads to a change in behaviour, which in turn encourages waste elimination. The Origins of Lean There is evidence that smooth flow of items in processes was seen as important as far back as the Arsenal in Venice in the 1450s. But the first person to apply mass production to an entire production process was Henry Ford in 1913 when he created what he called flow production. But Ford’s system, although it promoted smooth flow, could not easily provide variety. The Model T was limited to one colour and to one specification so that all Model T chassis were identical. When automakers tried to produce many different models, each with many options it resulted in processes with much longer throughput times. Progressively larger and larger machines were installed that ran faster and faster, apparently lowering costs of processing, but actually increasing throughput times and inventories. In the 1930s, Taiichi Ohno, and others at Toyota believed that it might be possible to provide both smooth, fast process flow and wide variety. Their ideas developed into what by the 1960s was being called the Toyota Production System. The best known of all descriptions of the ideas underlying lean operations is The Machine That Changed the World (1990) by James P. Womack, Daniel Roos, and Daniel T. Jones (http://www.lean.org/Bookstore/ProductDetails. cfm?SelectedProductID=160). In a later book, Lean Thinking (1996), James P. Womack and Daniel T. Jones distilled these lean principles even further to five: • Specify the value desired by the customer. • Identify the value stream for each product providing that value and challenge all of the wasted steps (generally nine out of ten) currently necessary to provide it. 239 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Make the product flow continuously through the remaining, value-added steps. • Introduce pull between all steps where continuous flow is possible. • Manage toward perfection so that the number of steps and the amount of time and information needed to serve the customer continually falls. The Lean Enterprise Institute, who specialise in the practice of lean ideas in a variety of contexts, recommend the following stages in applying lean principles. Specify value – As Womack and Jones note in Lean Thinking, ‘The critical starting point for lean thinking is value. Value can only be defined by the ultimate customer. And it's only meaningful when expressed in terms of a specific product (a good or a service, and often both at once), which meets the customer's needs at a specific price at a specific time.’ Lean must focus on the customer when specifying and creating value. Neither shareholder needs, nor senior management¹s financial mind-set, nor political exigencies, nor any other consideration should distract from this critical first step in lean thinking. Identify the value stream – The value stream is the set of all the specific actions required to bring a specific product through the critical management tasks of any business: the problemsolving task running from concept through detailed design and engineering to production launch, the information management task running from order-taking through detailed scheduling to delivery and the physical transformation task proceeding from raw materials to a finished product in the hands of the customer. Identifying the entire value stream for each product is the next step in lean thinking, a step that firms have rarely attempted but which almost always exposes enormous, indeed staggering, amounts of waste. Examine flow – Only after specifying value and mapping the stream can lean thinkers implement the third principle of making the remaining, value-creating steps flow. Such a shift often requires a fundamental shift in thinking for everyone involved, as functions and departments that once served as the categories for organising work must give way to specific products and a ‘batch and queue’ production mentality must get used to small lots produced in continuous flow. Interesting, ‘flow’ production was an even more valuable innovation of Henry Ford¹s than his better-known ‘mass’ production model. Introduce customer pull – As a result of the first three principles, lean enterprises can now make a revolutionary shift: instead of scheduling production to operate by a sales forecast, they can now simply make what the customer tells them to make. As Womack and Jones state, ‘You can let the customer pull the product from you as needed rather than pushing products, often unwanted, onto the customer.’ In other words, no one upstream function or department should produce a good or service until the customer downstream asks for it. Pursue perfection – After having implemented the prior lean principles, it ‘dawns on those involved that there is no end to the process of reducing effort, time, space, cost and mistakes while offering a product which is ever more nearly what the customer actually wants,’ write Womack and Jones. ‘Suddenly perfection, the fifth and final principle, doesn’t seem like a crazy idea.’ 240 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – Volvo falls to the power of lean Some may find the story of how Volvo moved towards adopting lean principles throughout its auto making plants a little depressing. After all, the radical and worker-centred plants at Kalmar and Uddevalla seemed to hold out the promise of ‘work with dignity’. Certainly, to those whose view of assembly line working was still influenced by Charlie Chaplin’s Modern Times, the philosophy behind Volvo’s experimental plants seemed to give control back to the people who actually produced the automobiles. And although neither of these plants were failures as such (high quality standards were achieved and, broadly, workers seemed happy with their extended tasks), they just could not match the combination of benefits that came from adopting lean principles. Of course, proponents of lean would argue that not only do automobile plants designed on just-in-time principles give better quality, faster throughput and lower costs they also provide the opportunity for operators to have a more meaningful level of involvement in process improvement. One may or may not, accepts that argument. But this is a story that demonstrates the power of lean principles in automobile manufacturing. It may also be a demonstration that there is a globalised market in ideas as well as products. Business Process Re-engineering (BPR) BPR can be defined in different ways, Here are two : ….the fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in critical, contemporary measures of performance, such as cost, quality, service and speed4….and….‘Business Process Reengineering….. seeks radical rather than merely continuous improvement. It escalates the effort of ……. (lean) …… and TQM to make process orientation a strategic tool and a core competence of the organisation. BPR concentrates on core business processes, and uses the specific techniques within the …. (lean) ….. and TQM tool boxes as enablers, while broadening the process vision’.5 In fact, almost all definitions stress the idea of identifying a number of business processes, usually assuming that there are a number of ‘core’ business processes. There are two ‘schools of thought’ with BPR. The first starts with no preconceptions about what the most important endto-end processes will be in any given organisation. The second prefers to identify a number of ‘classes’ or ‘types’ of core process. Both approaches share the common idea that there is a collection of interrelated tasks that solve a particular issue. But there is no universal agreement on what the main core types of business process are. Some typologies use an internal organisational task approach. For example: • Management processes – the processes that govern the operation of a system, including 'corporate governance', 'resource allocation' and 'strategic management'. • Operational processes – the processes that are part of the core business, and that directly add value, including manufacturing, service provision, procurement, marketing and sales. 4 Hammer, M. and Champy, J.

(1993) Business Process Reengineering: Break Point Strategies for Market Dominance, New York: John Wiley & Sons. 241 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Supporting processes – these support the core processes, including accounting, payroll, recruitment and IT. No matter how one defines overall processes, there are some generally agreed guidelines on how BPR should be approached. One commercial report combines data from three benchmarking studies to present a picture of process redesign and reengineering projects as well as views on the mistakes to avoid in BPR projects6. Its key findings areu: • The need to reduce cost/expense was the most frequently cited business driver for reengineering projects with competitive pressure, poor customer satisfaction and poor quality of products and services rounding out the top-four. • The top activity that project teams would do differently on the next project is more effective change management. • Teams whose projects were driven or heavily supported by top management were more likely to complete their project at or above expectations. • Participants overwhelmingly indicated that the planning stage, where scope and roles were set, was the most important phase in the project. • Resistance to change within the organisation was cited six times more often than any other as the number one obstacle to successful implementation. Six Sigma The chapter defines Six Sigma, as, ‘A disciplined methodology of defining, measuring, analysing, improving and controlling the quality in every one of the company’s products, processes and transactions – with the ultimate goal of virtually eliminating all defects’. A slightly different definition is provided by Isixsigma, an organisation of Six Sigma practitioners. '...Six Sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company's operational performance by identifying and eliminating "defects" in manufacturing and service-related processes. Commonly defined as 3.4 defects per million opportunities, Six Sigma can be defined and understood at three distinct levels: metric, methodology and philosophy...'. The origins of six sigma Engineers in Motorola during the 1980's used the Six Sigma title informally for an in-house initiative for reducing errors in manufacturing processes. Feeling that using a percentage scale to measure defects was insufficiently ambitious, they adopted the idea of using the 'defects per million' metric. And given that Six Sigma of variation was the equivalent of 3.4 defects per million, the term ‘Six Sigma’ stuck. Later, Motorola extended the idea to its other business processes. More significantly ‘Six Sigma’ became the in-house brand name for its performance improvement methodology. Within a few years, other companies, most notably Allied Signal, had adopted some parts of Motorola’s improvement method, but it was when General Electric's 6 Prosci, ‘Best practice in Business Process Reengineering and Process Design', www.prosci.com 242 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual CEO Jack Welch heard of the success of the approach at Allied Signal and decided to implement Six Sigma in GE that the approach really started to be taken seriously by the business world more generally. GE claimed that, by the late 1990s Six Sigma had resulted in more than three-quarters of a billion dollars of cost savings. So, in around 10 years Six Sigma had become both a popular and influential improvement and a consultancy product in its own right. Yet, the organisations that were involved in Six Sigma’s development have slightly differing interpretations. For example, Motorola’s view is '...Six Sigma has evolved over the last two decades and so has its definition. Six Sigma has literal, conceptual, and practical definitions. At Motorola University (the company’s training and consultancy division), we think about Six Sigma at three different levels …[but]… essentially, Six Sigma is all three at the same time.' • As a metric • As a methodology • As a management system '...Six Sigma as a Metric: The term "Sigma" is often used as a scale for levels of "goodness" or quality. Using this scale, "Six Sigma" equates to 3.4 defects per one million opportunities (DPMO). Therefore, Six Sigma started as a defect reduction effort in manufacturing and was then applied to other business processes for the same purpose..' '...Six Sigma as a Methodology: As Six Sigma has evolved, there has been less emphasis on the literal definition of 3.4 DPMO, or counting defects in products and processes. Six Sigma is a business improvement methodology that focuses an organisation on: • Understanding and managing customer requirements • Aligning key business processes to achieve those requirements • Utilising rigorous data analysis to minimise variation in those processes • Driving rapid and sustainable improvement to business processes..' '..At the heart of the methodology is the DMAIC model for process improvement. DMAIC is commonly used by Six Sigma project teams and is an acronym for: • Define opportunity • Measure performance • Analyse opportunity • Improve performance • Control performance..' '...Six Sigma Management System: Through experience, Motorola has learned that disciplined use of metrics and application of the methodology is still not enough to drive desired breakthrough improvements and results that are sustainable over time. For greatest impact, 243 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Motorola ensures that process metrics and structured methodology are applied to improvement opportunities that are directly linked to the organisational strategy. When practiced as a management system, Six Sigma is a high performance system for executing business strategy. Six Sigma is a top-down solution to help organisations: • Align their business strategy to critical improvement efforts • Mobilise teams to attack high impact projects • Accelerate improved business results • Govern efforts to ensure improvements are sustained..' After Motorola’s original work, it was General Electric (GE) who were responsible for popularising the idea of Six Sigma. GE’s view of Six Sigma is as follows. '...Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services. Why "Sigma"? The word is a statistical term that measures how far a given process deviates from perfection. The central idea behind Six Sigma is that if you can measure how many "defects" you have in a process, you can systematically figure out how to eliminate them and get as close to "zero defects" as possible. To achieve Six Sigma Quality, a process must produce no more than 3.4 defects per million opportunities. An "opportunity" is defined as a chance for non-conformance, or not meeting the required specifications. This means we need to be nearly flawless in executing our key processes.' GE sees Six Sigma as revolving around a few key concepts. • What is ‘Critical to Quality’, that is what are the attributes that are most important to the customer? • Defining defects as anything that fails to deliver what the customer wants. • Process Capability is what your process can deliver compared with what customers want. • Reducing the variation in what the customer sees and feels. • Stable Operations that ensure consistent and predictable processes to improve what the customer sees and feels. • Designing to meet customer needs and process capability... The differences and similarities between the approaches It is careful to stress the importance of not putting all one’s faith in copying how any of these approaches have been implemented in other organisations. In fact one can question the universal appropriateness on the very idea of ‘best practice’. But, even if one accepts that there are points to be learned from ‘best practice’, there are some further points stressed in Chapter 3. • Senior managers sometimes use these new approaches without fully understanding them. • All these approaches are different. 244 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • These approaches are not strategies but are strategic decisions. • Avoid becoming a victim of improvement ‘fashion’. The various approaches contain common elements The chapter distinguishes between the approaches in terms of whether they ate top-down or bottom-up, and whether they attempt to dictate what to do or how to do it. However, all these approaches are capable of some degree of interpretation. A more realistic description of the differences between them is shown in Figure 3.1. This shows that there is some overlap between the approaches Figure 3.1 Each of the ‘new approaches’ positioned in terms of their emphasis on what changes to make or how to make the changes, and whether they emphasise rapid or gradual change and indicating the degree of overlap between them 245 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The chapter also describes the main ‘elements’ contained within each of the approaches that are reviewed. You may have noticed that many of these elements appear more than once, some of them several times. Figures 3.2 to 3.6 attempt to summarise these elements and how they fit into each approach. Figure3.2 The elements that go to make up the ‘new approaches’ reviewed with those emphasised by TQM highlighted 246 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 3.3 The elements that go to make up the ‘new approaches’ reviewed with those emphasised by Lean highlighted 247 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 3.4 The elements that go to make up the ‘new approaches’ reviewed with those emphasised by BPR highlighted 248 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 3.5 The elements that go to make up the ‘new approaches’ reviewed with those emphasised by ERP highlighted 249 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 3.6 The elements that go to make up the ‘new approaches’ reviewed with those emphasised by Six Sigma highlighted Implementation problems The main barrier to adopting the new ideas when they were first proposed was overcoming the cognitive challenges posed by ideas that were counterintuitive to those of a traditional mindset. For example, the approach taken to quality by Japanese automobile manufacturers such as the Toyota Motor Company were met with incomprehension and incredulity when they were first articulated. For example, Cole quotes the following reaction of Toyota’s Quality Vice-President when asked whether continuous improvement really did have merit.7 'There has always been a problem because to research a 20 yen problem you have to spend 100 yen. However, we have stopped arguing about whether the research compensates for the loss in money. We stopped it 20 years ago. This is because failure cost is really only a small part of the total cost. For example, with our warranty system a customer will bring a faulty automobile which we fix for free. So, it takes a certain amount of money on our side for repairs. But the customer must pay for gasoline to bring the car to the shop, and he must find a way to get home, plus he will not be able to use the car for a certain period. And since the car is not being used, this is a minus for the national economy. Therefore, we are not covering all these losses with the 7 Cole, R. E. (1998) Learning from the quality movement: What did and didn’t happen and why? California Management Review, Vol. 41, No. 1. 250 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual money we use at the factory to repair the car. In short, the losses far exceed the costs we incurred fixing the problem.' As Cole points out, critical to his response are the implicit assumptions that the unmeasured customer and society incurred costs will become company costs (through negative reputational effects) if not addressed and that reducing them, even if we can’t measure them in a precise fashion, is well worth the investment. On a similar theme, Nadler identified what he regarded as quality-hostile assumptions to the adoption of TQM (again, this list could be used or adapted for almost any of the new approaches). This is shown in Table 3.3. Table 3.3 Quality-hostile assumptions8 Barriers Corporate purpose Customers Performance People 8 Illustrative assumptions • Our overriding purpose is to make money and produce short-term shareholder return. • Our key audience are the financial markets, in particular the analysis. • We are smarter than our customers and know what they really need. • Quality is not a major factor in customer decisions; they cannot tell the difference. • It costs more to provide a quality product or service and we will not recover the added cost. • The law of diminishing returns makes continuous improvement unworkable. • Strategic success comes only from large breakthrough improvements rather than continuous improvement. • The way to influence corporate performance is portfolio management and creative accounting. • We will never be able to operate competitively at the lower end of the market. • Managers are paid to make decisions; workers are paid to do, not to think. • We do not trust our people. • The job of senior management is strategy not operations or implementation. • The key disciplines for senior management are finance and marketing. Adapted from: Nadler D, (1992) Organizational architecture, San Francisco: Jossy-Bass . 251 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Problem solving and improvement Organisation • To err is human; perfection is unattainable and an unrealistic goal. • Quality improvement can be delegated; it is something that top management can tell middle management to do to the bottom of the organisation. • Celebrate success and shun failure; there is not much to learn by dwelling on our mistakes. • If it ain’t broke don’t fix it. • Functional loyalties take precedence over other loyalties. • An emphasis on systems inevitably leads to deadly bureaucracy. Of course, as the chapter points out, there is a mirror-image barrier to overcoming cognitive challenges. That is, managers take on an uncritical or an evangelical view of a new idea. ‘Swallowing an idea whole’ without any understanding or critical evaluation of its suitability inevitably leads to disappointment and disillusionment. This is why there is such merit in putting these ideas together, comparing them and attempting to understand their similarities and differences. The learning context of adopting new approaches Even organisations that have made significant improvements in their operations should want to further develop their operations capability, and through that, their operational performance. Many firms look to a comprehensive education programme that will enhance the breadth and depth of operations capability throughout their management population. Yet, notwithstanding the progress that may have been made in some parts of an organisation, there is usually evidence to indicate room for further improvement. Common problems include the following:9 • There is some inconsistency of the messages coming out of different development interventions and in some cases confusion as to how different initiatives relate to each other. • Where individual improvement projects have been successfully implemented the learning often fails to be embedded throughout the organisation. • Some tools and techniques, although used in places, fail to have a significant impact because the underlying principles on which they are based are not properly understood. • The responsibility of operations managers for improving their processes is seen as secondary to maintaining on-going performance (keeping the show on the road). • There are very different levels of knowledge, experience achievement in different parts of the operation. 9 Slack and Betts (2008) Forgotten Heroes: Process Leadership in financial service operations, Research Report 8–50, opsman.org, forthcoming. 252 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • There is ‘initiative fatigue’ and lack of engagement. • There is some weakness in the understanding by middle managers of their strategic position, contribution and role. • There are potential issues with an improvement culture that may be seen as being top-down and directive. Such a culture may become less appropriate for an organisation moving towards relatively sophisticated improvement strategies. • There may be little understanding of how current operational performance compares with comparable operations, either internally or externally. 253 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 4 Capacity strategy Chapter aims Chapter 4 deals with capacity strategy. The capacity of any operation is usually taken to mean its capability of operating at a particular level. The chapter aims to: • Emphasise the importance of long-term capacity strategy as part of operations strategy. • Illustrate what is meant by capacity and capacity strategies and show some of the difficulties in using these terms. • Explain why capacity levels are set at particular levels, what economies and diseconomies come through scale, how the timing and magnitude of capacity change affect operations performance and summarise the key issues involved in the location of capacity. Introduction Not only does size matter in operations, size is a vitally important issue in determining how well an operation can serve its markets. Capacity strategy decisions affect all the significant measures of operations success: costs, service, revenue, return on assets, working capital, future capabilities and the overall image of the business. That means it’s an extremely important topic. Also, because it deals with often expensive physical assets one doesn’t get too many chances to get it right. Nor is capacity a straightforward issue. It is complex, both in the sense that it is not always easy to measure and in the sense that two similar operations with similar levels of overall capacity can, in reality, be very different in how they deploy their capacity. The chapter consists of three parts. The first takes a steady state view of capacity. It more or less ignores issues of growth or decline and concentrates on how organisations can configure their capacity given a particular level of demand. The second deals with capacity dynamics. In other words, how the quantity and nature of a company’s capacity is changed to match changing patterns of demand. The third looks at some issues that influence the location of capacity. Measuring capacity The chapter devotes some space to some of the problems of measuring capacity. Don’t underestimate this issue. Without a way of measuring capacity it is difficult to manage it strategically. Often, capacity is measured as output of products or services per unit of time. So, each of Volvo’s’ car plants will have a capacity of so many automobiles per week or per year. However, not all types of operations can measure their capacity in output. For example, a retail 254 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual chain of stores could measure its capacity in terms of the number of customers it serves, but that would not be a very meaningful figure. In fact, such an organisation would measure its capacity in thousands of square feet of floor space devoted to retailing. This is an input measure of capacity. The capacity of any operation’s unit also depends on the mix of products or services produced. Each of Volvo’s car plants will need to take into account whether the mix of automobiles it makes remains constant. If it does not then its effective capacity will change. What is capacity strategy? The chapter provides a relatively thorough treatment of the main issues, both of configuring capacity and changing capacity, over the long-term. The key issues they identify are shown in Figure 4.1. • What should our overall level of capacity be? In other words, ideally, how big should our operation be? • What type of capacity to have? In other words, what should be the balance between the number and size of sites that make up our overall capacity? • What should our location strategy be? In other words, where should we place our various sites? • What should be the timing of any change in capacity? • What should be the magnitude of any change in capacity? The overall level of operations capacity The chapter concentrates on the more ‘rational’ perspective on determining capacity levels, and issues of economics of scale are, or course, important. Some say that the principle of an optimum size for any operation is one of the most important concepts in operations strategy. However, the text does not go into any depth on another aspect of size – how it affects the ‘softer’ issues of creativity and innovation. The following example illustrates this idea. 255 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The paradoxes of scale in the pharmaceutical industry There is a fundamental and intriguing paradox in the pharmaceutical industry. Scale is increasingly seen as important. Drug companies are merging to form a handful of industry giants. Yet, these giants are obsessed with the dynamic innovation capabilities exhibited by companies at the very opposite end of the scale spectrum, such as the small biotech companies with their start-up mentality and innovative culture. For example, GlaxoSmithKline (GSK) merged together from Glaxo Wellcome and SmithKline Beecham, then the number two and three in the industry, to form a $180 billion giant that became the largest company in the industry. Then, within 3 or 4 months it announced plans to separate out part of its research operations into six competing ‘biotechnology-like companies’. Each of these would concentrate on different disease areas, for example asthma and cancer. Tachi Yamada, head of research and development at GSK, was quoted at the time as justifying the move in terms of trying to achieve both scale economies and small company advantages at the same time. 'We have to be big and small at the same time. I had to design something that would take advantage of scale. But we know for a fact that big can sometimes mean bad. So we had to design something that could also maintain agility and entrepreneurial spirit.' Scale is particularly important, especially in the early stages of drug development where many hundreds of thousands of compounds are checked out on an almost production line basis, using advanced technologies to look for ‘hits’ against biological targets. Scale is also important in the later stages of development that rely on massive worldwide trials to establish the effectiveness of the drug and meet a myriad of regulatory standards around the world. Scale is again important to ensure that a company has all the required skills. Small companies cannot afford the investment in establishing a deep knowledge base across all the different specialisms necessary for modern drug development. The disadvantages of scale come in the middle of the development process. This is where the ‘hits’ from the basic screening processes are developed through to prototype drugs with what the industry calls ‘proof of concept’. That is, having sufficient scientific backing to warrant investment in massive drug trials. This part of the process needs creativity, agility, entrepreneurial spirit and, above all, an ability to be fast on your feet. None of these qualities come naturally to large and often bureaucratic drug corporations. This needs what Mr. Yamada at GSK calls ‘autonomy and accountable entrepreneurial spirit that maximises scientific interaction and internal competition for resources. You need something that looks and feels like a biotechnology company. GSK has created six units, two in the UK, one in Italy and three in the US. Each will concentrate on one of the different disease areas.’ GSK’s six units have no more than 500 scientists (small scale by pharmaceutical company standards) working on the drug hits that have been discovered during the screening process, organised at corporate level. If they manage to turn these leads into safe and effective drugs they could receive significant financial rewards. After all, independent biotech start-up creates plenty of millionaire scientists, 'Why,' says Mr. Yamada, 'should GSK not do the same?' GSK is not alone in trying to achieve economies of scale and entrepreneurial focus simultaneously. AstraZeneka is reshaping the layout of its largest research unit in the north of England which houses 2,500 scientists. Gone are the long corridors with their rows of isolated laboratories working behind closed doors. In their place the company is intending to build 256 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual hubs around which laboratories will be clustered and where scientists can interact, debate and test out their latest ideas. The idea is to stimulate innovation by mixing different ideas and different disciplines. Many of the most profitable drug discoveries have come from the intersections between different disciplines, or from ideas that have crossed the boundary from one discipline to another. For example, at Novartis, another major drugs company, 18 per cent of drug development projects actually began in another therapeutic area. Perhaps the most famous example of how boundary hopping stimulates creativity comes from Pfizer. Their blockbuster drug Viagra actually started out as a heart drug. Again, here is the paradox. Without entrepreneurial focus Viagra would never have been developed in the way it was. Yet without scale, there may not have been the appropriate therapeutic boundary for it to cross. Market forecasts One of the big issues for many companies when planning their capacity strategy (often for years ahead) is the reliability of market forecasts. Sometimes, these can be spectacularly wrong. This was the case in parts of the telecommunications industry between 1998 and 2002. The problems faced by the dot com companies was dwarfed by the over capacity issues of the companies that built the networks that carry telecommunications traffic. Their problems arose for four main reasons. First, their forecasts were just plain too optimistic. Although the Internet did bring substantial amounts of new traffic, growth was much slower than many in the industry were forecasting. Second, attracted by what they thought would be huge returns on their investment, both established players in the industry and several new entrants all built their own networks. Between 1998 and 2001 the amount of optical fibre cable in the ground increased fivefold. Third, there was a technical development that meant that signals could be put into and taken out of the fibre optic cables considerably faster than using the older technology. This effectively increased the transmission capacity of each strand of fibre by 100 times. Fourth, there is a high fixed cost of digging up the ground to lay the fibre in the first place. It therefore seemed sensible to put in more cable while you are at it. Then came the crash and with demand down, the volume of business slumped while the overcapacity in the industry kept prices low. So, profits were hit just as the companies were trying to pay off the debt they had incurred by investing in transmission capacity in the first place. Cost, volume, profit relationships If more capacity is provided than is justified by demand, the resources that constitute the capacity will be under-utilised. Conversely, if demand is greater than provided capacity, sales, and therefore revenue, will be lost. In this way the level of capacity chosen by an operation will directly affect its operating profitability. Beyond this, however, because the provision of capacity usually involves investment in resources, the decision also affects the level and nature of the operation’s asset base. The ‘Cost, volume, profit relationship’ is a simple, but still useful, approach to starting to understand capacity decisions. It is based on the differing relationships between cost and volume on one hand, and revenue and volume on the other. At activity levels below its capacity the average cost of producing each unit will increase because the fixed costs of the operation are being covered by fewer units produced or customers served The unit cost of producing or serving x units is then given by the formula: CX = (FC/x) + VC 257 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Where CX = the unit cost of producing x units FC = the fixed costs of the operation VC = the variable cost of producing one item or serving one customer This is illustrated in Figure 4.3 in the chapter. According to this formula the average cost of producing the units seems to reach its lowest point at maximum capacity; however, the actual average cost curve may not conform to this theoretical relationship. There may be cost penalties of operating the plant at levels close to or above its nominal capacity. Long periods of overtime may reduce productivity levels as well as costing more in extra payments to staff; operating equipment for long periods with reduced maintenance time may increase the chances of breakdown and so on. This usually means that average costs start to increase after a point that may be lower than the theoretical maximum capacity of the plant. Commentary on example ‘Ikea exploit the scale factor’ The chapter uses the example of Ikea to describe the concept of using scale to provide a competitive advantage. In retail this approach is sometimes called the ‘Category Killer’ approach. That is, the use of capacity as an aggressive competitive move. Capacity is used both to influence demand itself and to raise the risks for any competitor attempting to respond in similar terms. So far we have assumed that capacity strategy is concerned with providing sufficient capacity to match ‘natural’ demand. This is not always so. Sometimes capacity decisions can be made with the objective of influencing demand itself. The most obvious example of this is the ‘category killer’ in retailing. At one time the best-known category killer in retailing was the TOYS ‘R’ US toy chain, which started life in the United States but then spread all over the world. The company’s huge sites offered customers a wide selection of products at low prices. The sheer size of each operation gave customers the range of choice that attracted them in large numbers. The large numbers meant high throughput and the high throughput meant not only that the company could build large capacity, low transaction cost sites but also that it could win substantial discounts from toy manufacturers, reducing the cost even further (and attracting even more customers, etc.). In some of its markets (such as the USA) the TOYS ‘R’ US Company sold up to 20 per cent of all toys purchased. But then the company was accused of using its market dominance to pressurise its suppliers unduly. The resulting bad publicity did nothing to enhance the brand’s reputation. Economies of scale A key issue in capacity configuration is that of economies of scale. Broadly, this means that for any operation’s unit, as its size increases so its costs of producing its goods and services decreases. However, after a particular point diseconomies of scale start to kick-in. Thus, there is a theoretical optimum point for any operation where costs minimise. Economies of scale are really important in most industries, but don’t think this optimum level of capacity is always easy to discover. It can change with the mix of activities the operation has to cope with and it is just as influenced by 'soft' or attitudinal issues as it is by hard technical ones (see the example on Whole Foods Markets in the text). 258 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Economies of scale manifest themselves in terms of decreasing total cost per unit as capacity increases. These savings arise through: • Spreading overheads – an increase in capacity may not require a proportional increase in fixed costs, for example administration and insurance costs, resulting in company overheads being spread over a greater output. • Dedicated technology– an increase in volume and a reduction in non-productive costs, for example set-up costs, investment in work-in-progress, may be achieved by dedicating resources to a limited range of products and services or through a move away from general purpose technology. • Improved technology – an investment in more automated or more technically advanced equipment may have the effect of reducing variable costs, for example direct labour costs or material wastage. Despite possible savings through economies of scale, there may be costs and risks associated with increasing capacity: • The cost and associated risk of increasing borrowing to fund the investment in additional capacity. • The risk and costs associated with having idle capacity if the expected demand volumes do not materialise. • The costs associated with having an imbalance of types of capacity, if some degree of dedication has taken place, that is not the appropriate variety of demand. • The risk of incurring unforeseen costs with the introduction of new technology, where there may be little knowledge or experience of installation. • The costs of having spare capacity whilst demand catches up with capacity. • Diseconomies of scale – some costs may increase as capacity is increased. These are costs associated with having to distribute goods over a wider area, the costs of additional management structure, the costs of additional control systems to cope with the added complexity from extra volumes, and the risks associated with being big. Commentary on example: ‘So why should Cemex want to be bigger?’ The Cemex example is interesting because of the company’s attitude to economies of scale. One of the reasons that businesses like to grow is that it provides opportunities for conventional economies of scale – merging head offices, consolidating shared services, allowing sites to specialise and so on. Cemex certainly realises that these benefits are important, but they also stress the importance of two other factors, both of which are a function of Cemex’s operations capabilities. The first factor is that Cemex believes that they have a superior way of managing their type of operations. Their attitude is, ‘We are better at managing these types of processes than anybody else in the world. Therefore, every time we take over another company it’s an opportunity for us to exploit and gain value from our operations capability.’ 259 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The second factor is that they have grown their capability to manage the process of improving the operation of the acquired companies. It isn’t just that they can run better processes; it’s that they can move the acquired companies’ processes down the learning curve faster and more effectively than other predator companies. What drives scale economies? The idea that large-scale operations allow cost savings applies to many areas of business activity. And although economies of scale are often thought of as being primarily an issue of reduced operational costs following from the ability to spread fixed costs over a larger volume of output, there are other savings, some of which are especially evident when firms merge. Here are two examples. • When Ford took over the car-making division of Sweden’s Volvo for $6.45 billion, it made relatively little difference to Ford’s overall size. Volvo’s modest output of less than 400,000 cars per year was tiny by world standards. Yet, the effect on Volvo’s ability to compete was significant. Even in the short term, cost savings could come from tapping into Ford’s logistics and purchasing functions. Ford’s logistics network in the US could easily cope with Volvo’s products and the United States was Volvo’s biggest market. Similarly with purchasing: although Volvo had its own platform designs, even in the short term, it could substitute some of Ford’s components that it bought from specialist suppliers. • Size matters in the pharmaceuticals industry, partly because of the escalating cost of research and development. This has led to mergers, such as that between Hoechst and Rhône-Poulenc. Combining these two European companies enabled them to attempt to compete with industry giants in the US, such as Merck, Pfizer and Bristol-Myers Squibb. Largely because of expensive new technology for discovering disease mechanisms and potential drugs, even the largest companies could not hope to compete across every disease area. However, the bigger the company, the more areas can be covered. Similarly, the cost of marketing was growing, particularly in the US, where direct-to-consumer advertising, including pricey television campaigns, was fuelling profitable sales. Again, though, only the largest companies could afford spending of this magnitude. Commentary on example: ‘Can you get too big?’ Whole Foods Market provides an interesting example of how economies of scale can be affected by brand image – both positively and negatively. As a food store, it brings in all the normal economies of scale that one could see in any other supermarket chain. However, it does this in a sector of the market where customers have a particularly strong image of themselves and why they shop for this type of produce. Many of the customers who prefer to buy organic food (and pay the premium that such products attract) simply do not like to think of such services being delivered by a large-scale, high volume operation. Of course, it may be that for every customer who is put off the Whole Foods Market brand there are several others who are attracted to the convenience or using its stores. Nevertheless, what is undeniable is that there is a link between the image of the Whole Foods Market brand and the scale of its individual operations and its total market share. 260 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The number and size of sites The number of sites the operation has and the size of those sites are clearly related. So, a business may have to choose between having a few very large sites (perhaps even one very large site), or many relatively small sites, or something in between. Of course, as the chapter point out, for most operations the range of options available is more limited than this. So, for example, a retail chain or a Government service, cannot always consider the option of having one huge operation serving the whole of their territory because they need to deliver local services. A minimum level of convenient geographical coverage is necessary to provide acceptable degrees of customer service. However, even in such high customer contact operations there is usually some degree of choice to be made. While the accident and emergency services provided by the Government have to be geographically well dispersed so as to meet customer needs, more specialist units, such as burns units, can afford to be fewer in number and (relative to demand) larger. Example – A voucher processing centre A company in the banking industry is planning to build a ‘voucher processing’ centre that will process cheques, credit card documents and so on for other retail financial services companies. Although demand is unsure, it is believed that it will be around 10 million documents per year. The capital cost of building the centre, together with document readers, automated sorting technology, sophisticated information technology, etc. will depend on the capacity of the centre. The higher the capacity of the centre, the bigger the building, the larger the capacity of the computer systems and the more document readers will be needed. Table 4.1 gives details of the capital costs, fixed processing and variable processing costs and capacity, for three alternative investment options. Table 4.1 The three alternative capacity investments for the bank Capacity of processing centre (documents/year) Capital costs (€m) Fixed costs per year (€m) Variable cost per document (€) 5 million 2.2 0.28 0.01 10 million 4 0.6 0.01 15 million 5.5 0.8 0.01 The retail banking customers pay, on average, €0.25 per document processed. Given that the forecast for the centre’s services are around 10 million documents per year, the company decides to build a centre with this capacity. Their (simplified) calculations are as follows. Capital cost = €4 million Operating cost per year = Fixed cost + (volume × variable cost) = 0.6m + (10m × 0.01) = €0.7m 261 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Revenue Profit Return = 10m × 0.25 = €2.5m = €2.5m − $0.7m = $1.8m = €1.8m/$4m = 45% But to the company’s great regret the forecasts turn out to be optimistic and annual demand is only 5 million documents per year. This is how the simple return on investment figures now look. Capital cost = €€m Operating cost = €0.6m + (5m × $0.01) = €0.65m = 5m × 0.25 = €1.25m = €1.25 − 0.65m = €0.6m = €0.6m/€4m = 15% Revenue Profit Return If the company had built a 5 million document capacity centre its return would have been acceptable, namely: Capital cost = 2.2m Operating cost = €0.28m + (5m × $0.01) = €0.33m = 5m × €0.25 = €1.25m = €1.25 − $0.33m = €0.92m = €0.92m/$2.2m = 41.8% Revenue Profit Payback Following a similar, but more comprehensive, analysis, the company could have explored the consequences of each of its three capacity options under a range of demand levels. It might even have refined its market research to the point where it felt able to assign probabilities to different levels of demand. Table 4.2 shows the crude payback figures for each capacity option at three levels of demand. It also shows probabilities of each level of demand actually occurring. 262 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Table 4.2 Simple return on investment consequences of capacity investment for different demand levels Annual demand (documents) Capacity of processing centre (documents/year) 5 million probability = 0.3 10 million probability = 0.4 15 million probability = 0.3 5 million 41.8% 41.8% 41.8% 10 million 15.0% 45.0% 45.0% 15 million 7.3% 29.0% 51.0% Using an expectation approach, the company can weigh each return on investment by the likelihood of it occurring. So, If a 5 million capacity centre is built Expected return = (0.3 × 41.8)+ (0.4 × 41.8)+ (0.3 × 41.8) = 41.8% If a 10 million capacity centre is built Expected return = (0.3 × 15)+ (0.4 × 45)+ (0.3 × 45) = 36% If a 15 million capacity centre is built Expected return = (0.3 × 7.3) + (0.4 × 29) + (0.3 × 51) = 29.1% So, in this case the highest expected return is obtained when a centre with capacity only half of the expected demand is built. This is because of the basic financial consequences of failing to utilise a larger centre. Of course, there may be other market-related reasons why the company may not want to under-supply the market and so would build a larger centre. These will be discussed next. The purpose of this simplified example is that it demonstrates the magnitude of the effect that a mismatch between capacity and demand can have on the return on investment, or even the viability, of the company. The cost penalties of over-capacity can be very large compared, for example, with the cost savings normally obtained from routine improvement. Conversely the lost supply, revenue and profit opportunities of under-capacity can mean the difference between acquiring profitable market share and being consigned to be, at best, an industry follower. When to make a capacity change A key decision is when to make the introduction of extra capacity increments, or when to take out some capacity. The effect of this timing decision will be to change the balance between demand and capacity, and therefore the balance between potential revenue, costs and capital spend. Timing capacity introduction relatively early results in capacity levels that are always meeting, or in excess of, forecast demand, an approach called a ‘capacity leading’ strategy. Delaying the introduction of capacity can result in a demand-capacity balance that means that 263 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual only when new capacity is first introduced is capacity equal to demand. This approach is called a ‘capacity lagging’ strategy. Also described in the chapter is a third approach that is a compromise between leading and lagging but also involves some element of over-production during times of capacity leading so that the surplus production can be used to fulfil market demand in periods of capacity lagging. But this latter strategy can only be used where the output from an operation is storable, usually in make-to-stock manufacturing operations. Also, the working capital implications of this strategy could be prohibitive. Moreover, the risk of product obsolescence or deterioration may make it difficult to implement in all but the most robust and commodity-like of products. The magnitude of capacity change The chapter discusses the question of how big to make each unit of capacity expansion. However, it assumes that levels of demand and capacity plans are both known and certain. Yet, in any realistic capacity planning exercise there are two major types of uncertainty: • The uncertainty of future demand and • The uncertainty in the timing of the new capacity’s availability. Construction or delivery delays may push back the introduction of the new capacity; conversely, it may become available earlier than thought. Because of these uncertainties, capacity planning often has to include contingencies to allow for demand and capacity lead-time uncertainties. This obviously adds extra costs to any capacity provision plan, or alternatively, threatens a firm’s ability to capture revenue. Firms also may seek to reduce the level of uncertainty by adopting more flexible approaches to the provision of capacity. Where the capacity lead-time is long and demand difficult to forecast, these issues come to the forefront of capacity planning. Long capacity lead times One particular problem in timing and magnitude of capacity investment is illustrated by the airline industry. Orders need to be placed with aircraft manufacturers, often several years in advance of their delivery. These orders will be based on the airline’s best estimate of the demand for its services in several years’ time. But the airline industry is both cyclical and subject to disruption by unexpected international events. For example, the Gulf War in the early 1990s had a catastrophic effect on demand for flights, especially out of the United States. Similarly, the economic crises that faced nations in Asia in the mid-1990s reduced demand in an important and (hitherto) fast-growing part of the market. Similarly, the lead-time for aircraft manufacture is influenced by the balance between demand and capacity at the aircraft manufacturers (in the passenger aircraft industry, now consolidated to two major manufacturers, Boeing and Airbus). Like any other business, airlines do not like operating where demand is lower than capacity. (Utilisation in the airline industry is called ‘load factor’.) Low load factors translates into high unit costs and low margins, given that most costs for servicing a route are fixed by the number and length of flights rather than the number of passengers on the aircraft. On the other hand, too high a load factor can prevent airlines from obtaining highly profitable last-minute bookings and can affect the ability of customers to rearrange their itinerary. However, airlines do not like to forego growth when the potential is there. Historically, there has been a tendency for airlines to be optimistic when ordering aircraft during an economic 264 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual upswing in anticipation of high growth in the future. Unfortunately, given the lags in receiving the aircraft, they are often delivered at the start of the next cyclical downturn. Given that aircraft manufacturers charge relatively high prices for cancellation of options on their aircraft, capacity planning in this industry can be extremely risky. This is why many airlines lease much of their capacity, either from other airlines or from leasing companies (which may be owned by the aircraft manufacturers themselves). The airline will own its own ‘core’ fleet of aircraft and lease the balance on relatively flexible terms. By expanding its core fleet only gradually, and timing its leasing periods with those times it wants to retain the option of making permanent additions to its core fleet, the airline tries to reduce its exposure to capacity risks. Commentary on example: ‘Why industries have more capacity than they need’ This example explains why, in industries where there is significant overcapacity such as the automobile industry, companies often call for capacity reduction….. as long as it’s not their capacity that has to reduce! There is always the hope that ‘they will be last man standing’ after competitors have closed down their own capacity. It also explains why there is always a tendency to add more capacity even when there is already too much capacity in the industry. As one manager put it, 'Sure, I’m building a new plant when there is already capacity in the industry. But my plant will be the newest and the best. It won’t be my plant that’s left lying idle. Using decision trees in capacity strategy Decision trees can be used for exploring and illustrating decisions made under uncertainty, such as the capacity timing decision. Decision trees are a formalisation of any decision that has a number of options, the outcomes from which future and uncertain events will be affected. Once drawn, they can be used to organise the use of a simple expectation probability theory, so as to choose the option with the best expected outcome (although other decision criteria may be used, such as avoiding the worst outcomes). Figure 4.2 shows a simple decision-tree representation of a capacity timing decision. Here, a firm needs to choose between expanding this year or not. Expanding its capacity will cost it $8 million. However, it faces uncertain future demand. If demand does grow in the coming year, it is likely to do so to a level that would fill the new unit of capacity. If demand does not grow, it is likely to stay level and be roughly in balance with the company’s existing capacity. Forecasts indicate that there is a 50–50 chance of demand growing or remaining level. Profits from the operation will depend on whether capacity has been expanded and on the subsequent level of demand. 265 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual If the company decides to expand its capacity: There is a 0.5 chance of demand growing, earning the company $12m in profits. There is a 0.5 chance of demand being level, earning the company $5m in profits. So expected profits = (0.5 × 10) + (0.5 × 3) = $6.5m But the company would have paid out $8m to expand its capacity. If the company does not expand its capacity: The company will earn $5m in profits whatever happens to demand. Given these outcomes, the company decides that it does not wish to spend $8m to have expected profits of $6.5m when it can be sure of $5m without any capital outlay (especially when there is a 50 per cent chance that it will earn $2m less than it would do without any investment). Sequential capacity decisions Decision trees are a useful, but very simplified, framework by which to structure capacity timing decisions. They are used, usually, as a ‘first-level analysis’. However, they are at their most useful when used to model sequential investment decisions. For example, suppose the company introduced in the theory box on decision trees extended its analysis to include the possibility of also expanding in year 2. The decision tree now looks more complex but it does enable a more useful analysis (see Figure 4.3). The decision tree again indicates the profits earned for each set of decision options, this time over the 2-year period. It also indicates that the probabilities of demand growing in the second year depending on whether it has grown in the 266 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual first year. To analyse this tree we need to take a perspective of how the second-year decision would be made, depending on what had happened in the first year. These are points C to F in Figure 4.3. At point C – expanded in Year 1 and demand grew. If company expands in Year 2, expected profits = (0.3 × 32) + (0.7 × 18) = $22.2 If company doesn’t expand in Year 2, expected profits = $24m The company would not choose to expand because expected profits would be lower and $8m investment is needed. At point D – expanded in Year 1 and demand was level. If company expands in Year 2, expected profits = (0.7 × 15) + (0.3 × 8) = $12.9m If company doesn’t expand in Year 2 expected profits = (0.7 × 17) + (0.3 × 9) = $14.36m Again the company would choose not to expand because expected profits would be lower and $8m investment is needed. 267 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual At point E – did not expand in Year 1 and demand grew. If company expands in Year 2, expected profits = $18m If company doesn’t expand in Year 2, expected profits = $8m The company would expand because, even with $8m expenditure, the cash flow is higher than not expanding. At point F – did not expand in Year 1 and demand was level. If company expands in Year 2, expected profits = (0.7 × 18) + (0.3 × 14) = $16.8m If company doesn’t expand in Year 2, expected profits = $8m The company would expand, again cash flow would be higher even with investment in extra capacity. Working back to points A and B. At point A there is a 0.5 chance of $24m profit. And a 0.5 chance of $14.6m profit (i.e. there would be no further expansion no matter what happened to demand). So expected profit at point = (0.5 × 24) + (0.5 × 14.6) = $19.3m At point B there is a 0.5 chance of $10m profit (after expenditure of $8m on the expansion). And a 0.5 chance of $8.8m profit (after expenditure of $8m on the expansion). So expected profit at point B = (0.5 × 10) + (0.5 × 8.8) = $9.4m The company should therefore expand in Year 1 because its expected cash flow (after the $8m for expansion) would be 19.3 − 8 = $11.3m higher than the expected profit of not expanding in Year 1. Then, if demand in Year 1 does grow (point C), or remains level (point D), no further expansion is justified. Note that extending the analysis for the further year has changed the original decision described in the theory box. Horizon time is an important issue in all capacity change decisions. Game theory and competitor activity Using the decision-trees to structure a capacity timing decision does allow us to include uncertainty, but the environment in which the decision is being made is assumed to be independent of the decision itself. So the chances of the market growing or remaining level were not affected by the company’s decision to expand or not. However, in most markets, rival firms will watch each other closely and shape their own actions on the basis of what their competitors are doing. Thus, the environment is not only related to the decision itself, but the relationship is rarely benign, or even neutral. In other words, there are significant issues in the competitive 268 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual environment that are controlled by competitors who will act partly in response to our decisions and usually against our interests. So, for example, a decision to expand or contract capacity at a particular point in time may be affected by how we believe a competitor might react. This is where ‘game theory’ is useful. Game theory is a study of the strategic behaviour of rational ‘players’, each of whom has a set of possible actions, or strategies, available to them. The outcomes of choosing a strategy depend on the action of the other players. Although studied by economists for more than 50 years, game theory has revolutionised some branches of economics over the past 20 years. Its power lies in modelling the choices available to companies in oligopoly markets. An oligopoly is the area between being a monopoly and having perfect competition. Thus, most organisations compete in an oligopoly, that is, there are a finite number of known competitors who take decisions in the light of how they believe the others will act. Figure 4.4 illustrates a typical game theory formulation for a capacity decision. Our own company and a competitor are the two major players in a particular market. We are both deciding whether to increase capacity. Currently the total demand of 100,000 units is shared equally between the two of us and we each have a capacity of 50,000 units. The market price for our products is 100 and our costs are 50 per unit. Thus we each make 50,000 × 50 = 2,500,000 profit. Demand in the next period is forecast to increase by 50,000 to 150,000. If we decide to increase our capacity by the standard increment of 50,000 units, our profits will depend on whether our competitor does the same. Similarly, if we decide not to increase capacity, again, our profits will depend on our competitor’s action. Figure 4.4 shows our forecasts for the outcome, both to ourselves and our competitor, depending on what we and the competitor decide to do. Arguably, the best outcome for us jointly would be for neither to increase capacity. This would result in under-capacity in the market, the same level of demand but higher prices. In fact, this will not happen. If we believe our competitor will increase their capacity, the profit to us will be 269 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual 2,250,000 if we also increase capacity, or 2,000,000 if we do not. We would therefore increase capacity. If we believe that our competitors will not increase their capacity, increasing our own capacity would result in a profit to us of 5,000,000. Not increasing our capacity would result in a profit to us of 3,500,000. We would therefore increase our capacity. Thus, in this case, unless we co-operate with the competitor, it is always in our interests to increase our capacity. Furthermore, looking at it from the competitor’s point of view, it is always in their interests to increase their capacity. In fact, this is not an unusual situation. It can be added to the list of reasons of why over-capacity exists in so many industries discussed in the example in the chapter on ‘Why industries have more capacity than they need’. Capacity decrease The chapter examines various strategies for changing capacity and illustrates them under conditions of increasing demand. Remember, however, that the same issues will apply when demand is decreasing. However, when managing decline there are an additional set of issues. 'Reducing capacity' sounds neutral when it is written in this technical manner, but of course it often means wrenching social disruption and severe personal individual stress for those people who once staffed the capacity that is being 'reduced'. For example, when 3,400 workers from the United Auto Workers (UAW) went on strike at General Motors’ metal-stamping factory in Flint, Michigan, within 6 days a components manufacturing plant within the group had followed suit and the dispute finally ended 54 days later. By that time 26 of GM’s 29 North American plants had been affected and the company had lost $2.3 billion. What had started as a local dispute about investment at a metal-stamping plant had turned into the longest and costliest strike in the company’s history. The cause of all this was the company’s difficulty in managing the reduction in its manufacturing capacity. Reducing levels of capacity is going to be difficult for any company when it involves taking away the livelihoods of individual workers. General Motors had a particularly difficult task in reconfiguring its capacity to compete with the high-tech, and often non-unionised, Japanese plants. At the time, GM was making almost $1,000 less on each vehicle it sold than its archrival Ford. Much of this extra cost was because it had too many factories that were too small and too old-fashioned in their work processes. At the time GM had 14 stamping plants like Flint, when it probably needed fewer than 10. However, GM’s real problems lay in the timing and manner of its capacity reduction plans. The UAW had negotiated its ‘pattern’ agreement with all the three big American car makers some time earlier. However, Ford and Chrysler had already done much of their slimming down when the agreement was struck. GM had to try to do the same under the more restrictive new agreement. Nor did GM’s approach to the problem make their life any easier. Their relationship with the UAW had always been poor. At one point, early in the dispute, they secretly moved stamping dyes out of the factory over a public holiday, an action the workers branded as underhand and sneaky. They were also accused, by union critics, of promising investment in exchange for better productivity and then reneging on the deal. Location of capacity The issue of location in the chapter is described as being influenced largely by two main factors. • Supply side factors such as labour costs, land costs, energy costs, transportation costs and community factors. 270 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Demand side factors that include labour skills, suitability of site, image of location and convenience for customers. However, sometimes the personal preferences and prejudices of individuals within a company can have a significant effect on location decisions. At other times a company is ‘there because its there’. That is, historical reasons have determined location and management have either not thought about any advantages that might be gained from moving, or judge that any advantages are not worth the disruption. The attractiveness of regions The chapter discusses what is becoming a more significant issue in location, namely the way individual cities, states or regions of the world are deliberately trying to make themselves more attractive to inward investment. The following example – ‘Why Japan Invested in the UK’ – tells the story of one particular stream of investment. It is worthwhile studying this because it contains some elements that are common to all the efforts of different regions to attract investment. Example – Why Japan invested in the UK The 1990s in particular saw many hundreds of Japanese companies setting up operations in Europe. Manufacturing companies particularly have recognised the importance of developing a foothold in the huge European market to avoid having to add European Union import duties to the cost of their products. The largest numbers of these companies have chosen to locate in the UK. Some large early arrivals, such as Nissan, were attracted to the UK by generous governmentfunded financial support and tax concessions in regional development areas. They recognised that although potential employees did not necessarily have the skills needed to make their products, they were willing to be trained and did not come with any ‘bad habits’ picked up from similar employment. Later arrivals had much fewer direct financial incentives, but saw the other advantages gained by the early arrivals. In some areas, such as Telford and Milton Keynes, a critical mass of Japanese companies developed, creating a flow of good publicity back to Japan and encouraging further interest in these locations. This success was reinforced by a growth in support infrastructure, such as Japanese schools, social activities and even food retailing to help the expatriate families feel at home. Another important factor was language. Many Japanese manufacturing companies are accustomed to trading and producing in the US, and so the English language is the first foreign language of most business people. Drawings of products and processes, instruction sheets and computer programs were often immediately available for use without further translation for the UK. This meant a lower risk of misunderstandings and mistranslation, smoothing communications between the new plant and head office in Japan. It also became apparent that both the quality and cost of labour were important reasons to locate in the UK. While many large indigenous manufacturing companies had been criticising the educational standard of the workforce, Japanese companies took great care to select employees who were keen to learn, adaptable, willing to work hard and able to create improvements. Some companies were able to quote exceptionally high levels of productivity and quality performance in the UK, as an example to their Japanese workforce. Others began to export products from the 271 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual UK to Japan. At the same time, the total cost of labour in the UK was relatively low, both due to hourly wage rates significantly below those typically paid in some other European Union countries, and also because of low indirect labour costs. Other significant reasons for a choice of the UK have been the relatively low rate of corporation tax, good communication links with most parts of the world and a stable political and social system. The development planning process is cumbersome (as in most advanced economies), but at least it is transparent and difficulties of bribery and protection do not usually arise. There are also other underlying factors that cannot be discounted: the UK is renowned for its excellent golf courses, spacious housing is available in the countryside near industrial development areas and London is known for its excellent shopping and leisure facilities. The climate, although not the kindest in Europe, is temperate and the rainfall is not unlike that in Japan. So, the main reasons why Japanese investors came in such large numbers into the UK (as opposed to other European countries) are as follows. • It is within the European Union, a large and affluent market, especially for the products of the companies that are located in the UK. Automobiles and electronic equipment are the obvious examples of this. Importing from outside the European Union would have incurred import duties or even limits on the number of products that could be imported. • The UK government was willing to give government-funded financial support such as grants and tax concessions to companies. This was especially true when the chosen locations were in areas of relatively high unemployment (this made it easier to square things with the European Union commissioners). It is also worth noting that, although some of the early locations had substantial inducements, later ones had less. • In some areas of the UK there was a strong industrial tradition that meant the labour force had skills that might be useful to the incoming companies. It is interesting though, that this was also regarded as a disadvantage by some companies who were afraid of the ‘bad habits’ of job demarcation and conservatism that had marked some areas. • Some factors were not ‘rational’ as such, but were nevertheless important. One example of this is the ‘critical mass’ issue. Simply because many other Japanese companies had located in the UK it was perceived as a safe place to come. This is partly to do with such things as the availability of Japanese schools, Japanese food stores and so on. Partly, though, it is also merely that the experience becomes a familiar one rather than one that is unfamiliar and therefore perceived as risky. • Clearly, the fact that the English speak, well ….English, is an advantage to any company with international operations. The Japanese especially, if they speak a foreign language, it is likely to be English. This is not only convenient, it also helps to reduce errors and misunderstandings through mistranslation. • The cost of labour, and just as important, the cost of employing labour, it would appear, was an issue. Especially when compared to continental European countries, UK labour rates, at the time, looked attractive. • An issue mentioned in the example but given relatively little space is that of, the prevailing business culture of the country. The UK was seen as a country where it was easy ‘to do business’. This was an image actively promoted by the government of the time. 272 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • The final point mentioned again may not be seen as purely ‘business like’ but nevertheless seems to have been important. The UK is seen by the Japanese as a good place to live. The climate is familiar to them, entertainment such as golf courses and leisure facilities are regarded as more than adequate, and the historical ‘heritage’ image of the country, it would appear, appealed! But, notwithstanding all these reasons for the UK leading the European inward investment table, other forces can work against the location as the commentary ‘Toyota moves to France’ makes clear (see below). Commentary on example: ‘Toyota moves to France’ This is another example of where the balance between market requirements and operations resource capabilities is seen to be the major driver of operations strategy. However, here we have an example of how brand image pressures (part of the set of ‘market requirements’ pressures) are both important and unusual in global terms. Two or three decades ago it was important where a car was made. Many countries preferred to buy cars designed and produced in their own country and preferably that came from a business quite clearly owned by shareholders (or sometimes the government) of the country. But the world is now far more global. One manifestation of this is that, in most markets, consumers care about the product, its characteristics and its price, but have grown used to the idea that the car may actually be made anywhere in the world. But not all markets are like this. The French market, for example, very much prefers to buy cars that are manufactured in France. Toyota figured that there was a distinct advantage to be gained from manufacturing at least some of its models in France if it was to be successful in the French market. Of course, as the example makes clear, that was not the only reason that Toyota chose not to simply expand its UK operation. However, it was a significant factor and highlights the importance of market image in some operations strategy decisions. Changing location If a company is small, notwithstanding any other advantages it may have, it is unlikely to enjoy many economies of scale. As it grows, it will presumably configure itself internally so as to capture the scale economies that come from its increased level of activity. This may mean adopting higher-volume technologies and gearing up their infrastructure to allow indirect resources to be used more effectively. As growth continues, eventually the level of activity in the operation will be such that any losses of scale economies from splitting the operation into two or more parts are relatively small. This is when total capacity decisions must also include location decisions. The argument for or against operating across a few relatively large, or many relatively small, sites was treated in the previous chapter. Here we extend the debate to include the issue of how the role of sites may vary or develop over time, especially when a company’s expansion includes overseas sites. 273 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Configuration and coordination Decisions relating to how organisations choose to locate their operations, and especially change the location of their operations, often distinguish between configuration decisions and coordination decisions.1 Configuration is broadly what we discussed in our treatment of location in the previous chapter. It means exactly where facilities are located and what resources are allocated to each location. Co-ordination refers to questions of how to integrate the activities of each site so as to achieve the organisation’s overall strategic objectives. In many ways coordination is more of an infrastructural decision and, indeed, we shall refer to it in later chapters when we discuss the development and organisation of operations resources. The reason for raising it at this point is that both configuration and co-ordination issues come into play when companies change their locations as a result of broad capacity dynamics. Example – breakfast cereals manufacturer A company that manufactures and markets breakfast cereals is entering a new regional market in a part of the world in which it has not operated before. Volume forecasts indicate that, after a slow start, while its brands establish themselves, volume will grow relatively quickly. The technology employed to manufacture breakfast cereals is of three types: ‘flaking’, ‘puff’ and ‘extrusion’. These technologies are mutually exclusive. Products that depend on flaking technology cannot be made on equipment designed for extrusion. Forecasts indicate that for the first year of operation the company will need three production lines, one of each technology. After the first year the company is likely to require several more of each technology. The dilemma for the company is whether they should start with one manufacturing location in which they could house the three different production lines, or alternatively, whether they should start with three locations, each devoted to a separate technology. The advantage of developing one mixed technology site is that, even in the first year of operation, the site is working with three lines that can share some general infrastructural costs such as supervision, planning and maintenance. The disadvantage is that after 2 or 3 years of growth, the site will be both large and complex because of the slightly different requirements of the three technologies. Developing three sites from the start would mean that in the long term each site could focus solely on the needs of one of the technologies and could therefore gain the improvements from specialising in a single technology. This is likely to mean higher degrees of process knowledge and better manufacturing performance in the long term. However, in the short term each of the three sites will be significantly under-utilised, only having one line in each, yet still require a certain degree of infrastructural services. In this example we have two sets of conflicting pressures. First, there is a conflict between the short-term needs of the organisation and its long-term needs. Having initially only one manufacturing site would minimise production costs in the short run but would be an inferior configuration in terms of the long-run development of its operations. This is because focused plants devoted to single technologies are easier to coordinate internally, which in turn can lead to long-term superior performance. The other conflict is between the familiar ‘market requirements’ and ‘operations resource’ needs. It may be that, in the long term, a number of sites, all of which use mixed technologies, may be better at serving different areas of the market, each area having an ‘all-purpose’ site that can serve all its needs. But, as we have just argued, more focused single technology sites may develop the operation’s resources more effectively. 1 Porter, M.E. (1989) ‘Changing patterns of international competition’, California Management Review, 28(2). 274 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The final choice for this company will depend upon its own assessments of market requirements, cost pressures and the potential for process improvement. The key point, however, is not so much what is best for this company but rather that the location decision has involved both configuration and co-ordination issues. What issues are important when changing the location of capacity? Changing the absolute level of capacity in a business and changing the location of sites are rarely independent decisions. For example, expansion may mean automatically having to choose a further location if the current location has insufficient room for expansion. Two issues tend to be considered in location change decisions. These are the configuration of what facilities are located where, and the co-ordination between those resources. Although co-ordination is more of an infrastructural issue, it is affected by the configuration of sites. Spanning both these issues is the role that is expected of individual sites. Some authorities recommend that individual sites should be expected to develop enhanced capabilities that can benefit other sites. The role of sites A further example of how the dynamic nature of location decisions can affect the more infrastructural side of operations strategy comes when the role, or contribution, of each site within an organisation is considered. Professor Kasra Ferdows calls this the ‘strategic role’ of sites.2 To identify these roles he distinguishes between two variables: The main motive for establishing the site – for example to gain access to low-cost inputs such as labour or raw materials, to use local technological resources such as specific software development skills or to provide proximity to a market such as the breakfast cereal example mentioned previously. The extent of the capabilities, or ‘technical activities’, at the site – is the site limited to simply carrying out activities under the complete control of a distant headquarters or, at the other extreme, is it responsible for the technological development of its products and services, processes planning, procurement, distribution, etc.? Bringing these two various sets of variables together, he identified six generic roles for sites (in fact, in developing these ideas Professor Ferdows is talking about manufacturing sites in an international context, but the ideas can be used more generally). See Figure 4.5 given below. 2 Ferdows, K. (1997) Making the most of foreign factories, Harvard Business Review, March–April. 275 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual In this manufacturing context the six roles for a factory that Ferdows identifies are as follows. • Off-shore factory – its role is limited to producing specific items at low cost. Local management have relatively little discretion as to how production is organised and most, if not all, product and process technology is likely to be dictated by head office. • Source factory – although again established primarily for low-cost production, managers in this kind of plant are allowed more discretion over how to exploit the opportunities they have to reduce costs. They may also have discretion on how best to distribute this knowledge to other plants. • Server factory – this type of plant is likely to be set up in order to serve specific regional markets, perhaps to reduce distribution costs or overcome tariff barriers. The way in which it produces its products, however, is likely to be dictated largely by its headquarters. • Contributor factory – although primarily serving a regional market, this type of factory may be expected to develop original ways of serving its market and test out new products that are later rolled out in other markets. • Outpost factory – these factories are set up in order to exploit some local factor that is unavailable elsewhere. As such, they are expected to supply information to other factories. • Lead factory – although set up originally to exploit local factors, a lead factory’s contribution has progressed to the point where it can educate other plants in some aspect of the firm’s business. It is a centre of innovation to which other parts of the organisation look for the development of unique capabilities. Ferdows’ main point is that organisations can gain advantage by developing the role of their locations from that where they represent a relatively passive unit of production capacity, through to a role where they are expected to develop and deploy unique capabilities that can be 276 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual transferred to other parts of the organisation. These trajectories of development generally move from a low level of discretion and capabilities through to increasing levels of ‘technical’ or knowledge-creating activity. Sites may also change their primary purpose. For example, those set up as outposts in order to gain local skills and knowledge may develop this in such a way as to reduce costs and therefore become ‘source’ plants, or develop new markets and thus become ‘contributor’ plants. This in turn may lead to development of unique levels of knowledge that qualify them as ‘lead’ plants. Commentary on example ‘Location Clustering around the typewriter’ This example highlights the importance of historical industrial development in shaping the trajectory of future growth. There are clear economies of location clusters once a particular level of clustering has been achieved. Like-minded companies, with similar needs, have an instinct to exploit these economies by clustering together. Michigan is dominated by auto makers, northern Italy by knitted garment manufacturers, Connecticut by insurers, part of the English Midlands by racing cars, North Carolina has its furniture makers and so on. The most famous cluster of all, though, is probably Silicon Valley in California. Microsoft may be based in Seattle, Compaq in Texas and IBM operates out of New Jersey, but the centre of gravity for computer technology companies is, by common consent, the area south of San Francisco whose core is Santa Clara County. But Silicon Valley is not an entirely recent creation. Back in 1938, Fred Terman, a professor at Stanford University, persuaded two of his students, Bill Hewlett and David Packard, to set up a company making electronic measuring equipment. In the 1950s Hewlett-Packard, together with several other companies, relocated to Stanford University’s new industrial park. From that point, other companies became increasingly attracted to the area because of the skill of its labour pool, the spread of its network of suppliers and relatively easy access to venture capital. In many ways the catalyst for all this was the excellence of its research and education institutions such as Stanford, Berkeley and the Palo Alto research centre. It has been estimated that more than 1,000 companies have emerged from Stanford University alone. Just as important is the culture that has grown up in the area. This may even be more important than any conventional economic or technological factors. The Silicon Valley culture has been characterised as including the following. • A tolerance of failure – companies go bankrupt, entrepreneurs learn what they did wrong and try again. • Mobility tolerance – staff leave companies, the original company is upset but the staff start their own outfits. A tolerance of failure – companies go bankrupt, entrepreneurs learn what they did wrong and try again. • Mobility tolerance – staff leave companies, the original company is upset but the staff start their own outfits. • People take risks – at the forefront of technological advances, risk taking becomes a way of life. One estimate has it that out of 20 Silicon Valley companies, four will go bankrupt, six will stay in business but lose money, six will make only a modest return, three will do reasonably well and one will do exceptionally well. 277 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Enthusiasm for change – fast-moving technology means that companies have to reinvent themselves continually. • Egalitarianism – Silicon Valley is open to men and women of all nationalities. Youth and success are often prized more highly than age and seniority. • Sharing – Silicon Valley is full of knowledge junkies whose chat sites, restaurants and social occasions are full of borrowed and shared ideas. • People take risks – at the forefront of technological advances, risk taking becomes a way of life.

Yet it is still a topic that dominates many businesses’ operations strategy discussions. This is because, ‘the network is the context in which an organisation’s operations strategy is developed’. Indeed some authorities hold the ‘supply strategy’ is a broader and more descriptive term for what here we call operations strategy. But our main interest with the network perspective in this chapter is the recognition that it is possible to exert varying degrees of influence over our network in order to serve our strategic goals. This chapter aims to: • Describe the concepts of a ‘supply network’ and ‘supply network strategy’. • Understand what is meant by the term ‘supply chain’. • Evaluate the factors influencing the degree to which a company should ‘do’ or ‘buy’. • Identify different forms of inter-organisational relationships such as contractual and ‘partnership’ relationships. • Understand the dimensions of supply network strategy that enable managers to achieve their strategic aims through the management of their network. Purchasing and supply strategy ‘Purchasing and supply strategy is the strategic direction of an organisation’s relationships with suppliers, customers, suppliers’ suppliers, customers’ customers, and so on. In particular, it includes such issues as ensuring that the organisation has an understanding of its supply networks, determining appropriate supply network relationships for its various activities, understanding supply network behaviour, in particular how the dynamics of a supply network will affect the organisation and how networks can be managed (or at least influenced) for the long-term benefit of the organisation’. When discussing supply networks, it is very important to be clear about the various levels of the network to which we refer. The chapter describes each of these levels, but it is important to 279 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual understand the differences as terminology can cause confusion in this subject. Figure 5.1 shows how they have viewed the three different ‘levels of analysis’. Figure 5.1 Three different levels of supply network analysis So, the three levels are: • The internal supply network – the interconnected network of ‘micro operations’ within a company. These may be departments, sites or whole divisions, depending on how the ‘company’ is defined. • The immediate supply network – the suppliers and customers (and co-operators) with which the company has direct contact. • The total supply network – the network of suppliers, customers, suppliers’ suppliers, customers’ customers and so on. In practice this concept is often limited to one or two ‘stages’ away from the focal company. Supply network and supply chain management is one of the most discussed topics in and around operations management/strategy. Yet there is considerable confusion relating to the definition of a supply chain or network (we have found over 400 differing, varied, but related definitions including, ‘demand chains’, ‘strategic purchasing’, ‘supplier development’, ‘efficient consumer response’, and so on also there are many sub-categories and different perspectives). However, the term ‘network’ is commonly understood, and in reality we find that industry structures do not conform to the simplified single supply chain. Here we examine supply networks from the viewpoint of the individual businesses that operate within them. In order to do this we must first clarify the nature of supply networks and the terminology used to describe them. 280 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – ‘What’s the nationality of your car?’ This example makes a fairly obvious point; namely that the ‘nationality’ of a product is not always easy to identify, and that the publics’ perception of a car’s nationality is often at odds with the reality of where it is designed and made. Of course, this phenomenon does not apply only to automobiles. Many electronic goods are made (and sometimes designed) globally rather than in the country with which the brand name is identified. This has some important implications both for how supply networks are configured and for how brands are managed. However, there is conflicting evidence of how important a brand’s ‘nationality’ is to its success. Some businesses fear that moving their supply network outside of their ‘brandidentified’ region would be damaging. For example, Absolut Vodka is still made in Sweden in spite of the fact that its major market is the United States. Yet VW is happy to manufacture its automobiles outside of Germany, relying on their customers’ ability to value the quality of German engineering and German management even if the automobile is made elsewhere. Why take a supply network perspective? The chapter argues that there are a number of competitive benefits of companies visualising themselves as part of the whole supply network, including; • It enhances understanding of competitive and cooperative forces • It confronts the operation with its strategic resource options • It highlights the ‘operation to operation’ nature of business relationships In addition, a supply network perspective also promotes a focus on long-term issues. There are times when circumstances make some parts of a supply network weaker than their adjacent links. A major plant breakdown, for example, or a labour dispute, might disrupt an operation. How then should its immediate customers and suppliers react? Should they exploit the weakness as a legitimate move to enhance their own competitive position or should they ignore the opportunity, tolerate the problems, and hope the customer or supplier will eventually recover? Sometimes short-term adversarial opportunities seem too good to miss, and short-term issues too pressing to give thought to how the total supply network is being affected. However, a longer term view would be to weigh the relative advantages to be gained from assisting or replacing the weak link. Similarly, when considering investment decisions, an operation will look at its current, and likely future, levels of demand. When the operation’s ‘vision’ is restricted to its immediate customers, the overall industry dynamics shaping demand may not be obvious. Extending the operation’s vision to include its total supply network will sensitise the operation to trends in parts of the network which may take time to work through to its own level in the industry. A routinely established habit of considering all external relationships as part of the total supply network is not a guarantee of long-term self-interest or an antidote to shorttermism, but it does help. Also a supply network perspective identifies any particularly significant relationships. Any analysis of networks must start with an understanding of what constitutes competitive performance at the ‘downstream’ end of the network. This helps to identify the parts of the network that contribute most to satisfy end-customer requirements. This analysis will probably show that not all companies’ contributions will be equally significant. For example, the important end customers for some types of automotive are the installers and service companies 281 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual who deal directly with end consumers. They are supplied by ‘inventory holders’ whose competitive success relies on a combination of price, range and, above all, a high availability of supply. This means having all parts in stock and delivering them fast. Suppliers of parts to the stockholders can best contribute to their customers’ competitiveness partly by offering a short delivery lead-time but mainly through dependable delivery. The key players here are the stockholders. Without effective service levels and competitive prices from them, the end customers will not be as likely to buy the products of the parts manufacturer. The best way of winning end-customer business is by helping the key players in the network; in this case by giving them prompt delivery which helps keep costs down while providing high availability of parts. But perhaps the most important implications of a supply network perspective are the idea put forward that it highlights the ‘operation to operation’ nature of business relationships. For the whole supply chain to operate effectively, the chain of operations must interface effectively with each other. For that to happen each operation in the network must understand the nature of their suppliers’ and their customers’ operations. After all, how can any company sell goods and services to a customer when it doesn’t fully understand how it can make that customer’s life easier? Similarly, how can any operation help its suppliers to supply more effectively if it doesn’t understand the nature of its supplier’s operations? This implies a very significant reorientation in the mindsets of the people in the organisation who have not traditionally seen themselves as requiring operations management knowledge. But, is ‘purchasing and supply’ really part of operations strategy? This quite clearly establishes the importance of purchasing and supply strategy not only within operations strategy but also as an important component of business strategy generally. This is a fair reflection of the way this area of strategic thought is developing, and you may well find that the network concept is discussed in other courses. For example, Marketing Strategy has long been concerned with the issue of linkages in the supply network, especially the relationships that exist between industrial customers and suppliers, as well as the way a company should ‘position’ itself in its industry (or put another way, ‘determine its preferred role within the supply network’). Certainly there are parallels between the writings of those Marketing authors who focus on industrial markets and customer–supplier relationships, and the developments in operations strategy. Increasingly we are seeing Marketing authors addressing the nature of interaction and relationships between firms, as opposed to the bare transactions that occur between, which can be seen as a mirror image of the ‘supplier development’ idea adopted by many Operations authors. However, what we need to clarify here is the place of supply network strategy within an operations strategy course. Whilst Marketing views the companies it supplies as customers, in operations we think of customers in our supply networks as other operations. These operations have their own characteristics of demand, process design, control and planning, all of which have a direct and significant impact upon our operations and its strategic performance. By thinking about our customers in this way, we recognise the operations task we are faced with expressed in terms of the provision of the right mix of quality, speed, dependability, flexibility and cost to help our customer’s operations managers to operate more effectively. So, our focus in this course is with an ‘operations to operations’ perspective of the supply network both towards our suppliers (‘upstream’) and our customers (‘downstream’). 282 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example ‘Extracts from Levi Strauss’ Global sourcing policy This example simply selects some extract from one business’s global sourcing policy in order to illustrate how companies who make extensive use of outsourcing, especially to low cost regions of the world, are increasingly conscious of the interface between choosing suppliers and corporate social responsibility (CSR). The drivers for policies such as this one may well include genuine ethical concerns, but also certainly include the reputational risk implications of being identified with unethical supply practice. That is certainly what is driving companies such as Nike. Over the last few years Nike has received negative publicity for their sourcing practices. In particular, the company has received criticism after claims emerged of poor working conditions at some of their suppliers’ plants. For example, in 2007 Nike suspended a Pakistan-based football maker for breaking its code of conduct. Only when Silver Star, a company from Pakistan’s Punjab province, had met Nike’s ethical specifications was it allowed back. The new agreement with Silver Star specified that all workers must be registered full time employees, all workers must receive social benefits, and all workers will have the right to unionise and collectively bargain. No less than Mark Parker, Nike's President and CEO, said ‘We hope this is the beginning of broader, positive systemic change for workers, and that the example Silver Star sets will help Pakistan’s soccer ball industry create a new model of responsible, globally competitive manufacturing’. Nike’s annual corporate responsibility report reinforces their policy, claiming that they, ‘are making strenuous efforts to cut down the amount of overtime carried out in their 700 contract factories over the next four years’. And, according to Mark Parker ‘We see corporate responsibility as a catalyst for growth and innovation’. Inter-operations relationships in supply networks There are many trends in how supply networks are managed. Broadly speaking, these are as follows. • An increase in the proportion of goods and services outsourced – generally companies are performing fewer activities in-house. The idea of ‘core capability’ is important here. The discrimination between what is a core capability to the long-term competitiveness of the organisation and what is less strategically important has often provided the basis for outsourcing, the argument being that a company can achieve both better efficiency and more operational effectiveness by concentrating on a few important activities and outsourcing the rest. Especially for companies that deal in a number of specialised technologies, it has proved almost impossible to maintain expertise in everything. Subcontracting at least some of these activities to other parts of the network allows access to technological innovations while reducing the risk of being stuck with outdated resources. • Organisations are reducing the number of their suppliers – for activities of any reasonable complexity there is a transaction cost of buying in products and services. Specification and quality levels must be agreed, delivery times organised and prices agreed. Reducing the number of supply contacts will potentially reduce these transaction costs. Just as important, the time saved managing a large number of suppliers can be invested into improving the quality of fewer, more secure and potentially more valuable relationships. 283 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Generally organisations are attempting to develop ‘partnerships’ with suppliers and customers. This may take the form of some combination of long-term contractual agreements, colocation of resources, transparency of cost information, integrated systems and procedures, automated electronic financial communication, and so forth. • Not all these changes happened at the same time. Generally, companies started to reduce the scope of their activities before understanding the importance of developing their relationships with customers and suppliers. Thus, many companies moved from the classical vertically integrated operation through to what is now sometimes called traditional supply management. This reduced the scope of what an organisation chose to do internally but relied on simple market mechanisms to determine which suppliers should provide the goods and services hitherto produced in-house and which customers should be given priority in terms of service and supply. Although the trend towards outsourcing activities has continued, the parallel trend towards closer relationships with fewer suppliers has moved supply network relationships towards ‘partnership’ supply. Three types of relationship The chapter implies three different ways of categorising the relationships between players in supply networks, although they do indicate that each of these categories can include somewhat different approaches. These three pure types of relationship are as follows. • Vertical integration – that is doing activities in-house. • Contractual (market) relationships – using many suppliers with little closeness in the relationships. • Partnership relationships – involving attempts to build long-term and close relationships with a relatively few suppliers. Do or buy? The vertical integration decision Vertical integration is the extent to which an organisation owns the network of which it is a part. At a strategic level it involves an organisation assessing the wisdom of acquiring suppliers or customers. At the level of individual products or services it means the operation deciding whether to make a particular component or to perform a particular service itself, or alternatively buy it in from a supplier. An organisation’s vertical integration strategy can be defined in terms of:1 • The direction of integration; • The extent of the span of integration; • The balance among the vertically integrated stages. 1 Hayes, R. and S.C. Wheelwright (1984) Restoring our Competitive Edge: Competing through manufacturing, Wiley. 284 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The direction of vertical integration If a company decides that it should control more of its network, should it expand by buying one of its suppliers or should it expand by buying one of its customers? The strategy of expanding on the supply side of the network is sometimes called backward or ‘upstream’ vertical integration and expanding on the demand side is sometimes called forward or ‘downstream’ vertical integration. Backward vertical integration, by allowing an organisation to take control of its suppliers, is often used either to gain cost advantages or to prevent competitors gaining control of important suppliers. This is why backward vertical integration is sometimes considered a strategically defensive move. Forward vertical integration, on the other hand, takes an organisation closer to its markets and allows more freedom for it to make contact directly with its customers. For this reason, forward vertical integration is sometimes considered an offensive strategic move. The extent of vertical integration Some organisations deliberately choose not to integrate far, if at all, from their original part of the network. Alternatively, some organisations choose to become very vertically integrated. Take many large international oil companies, such as Exxon, for example. Exxon is involved with exploration and extraction as well as the refining of the crude oil into a consumable product – gasoline. It also has operations that distribute and retail the gasoline (and many other products) to the final customer. This path (one of several for its different products) has moved the material through the total network of processes, all of which are owned (wholly or partly) by the one company. The balance among stages The final vertical integration decision is not strictly about the ownership of the network; it concerns the capacity and, to some extent, the operating behaviour of each stage in the network which is owned by the organisation. The balance of the part of the network owned by an organisation is the amount of the capacity at each stage in the network which is devoted to supplying the next stage. So a totally balanced network relationship is one where one stage produces only for the next stage in the network and totally satisfies its requirements. Less than full balance in the stages allows each stage to sell its output to other companies or buy in some of its supplies from other companies. Fully balanced networks have the virtue of simplicity and also allow each stage to focus on the requirements of the next stage along in the network. Having to supply other organisations, perhaps with slightly different requirements, might serve to distract from what is needed by their (owned) primary customers. Some advantages of vertical integration/insourcing The chapter cites a number of advantages of vertical integration. • Securing dependable delivery – The most fundamental reason for engaging in some process in-house rather than outsourcing it is that it can’t satisfactorily be outsourced. In some cases there may not even be sufficient capacity in the supply market to satisfy the company. It therefore has little alternative but to supply itself. For example, some specialist electronic components are manufactured in-house by equipment manufacturers until potential suppliers have developed the capacity and knowledge to supply from outside. 285 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Reducing costs – This reason sounds straightforward but isn’t. Sometimes this is a good reason for moving some activity in-house. But in addition to direct costs there must be some allocation of indirect costs. If there really is no allocation of indirect costs it means that the company is inefficiently run anyway (which is an argument for improving the operating practices of the company rather than vertically integrating any new process into its activities). Cost saving through integration is also dependent on the assumption that start-up and learning costs will be relatively trivial, and that the cost savings will be such as to maintain, or even improve, the return on assets of the company, allowing for any increase in investment necessary to perform the activity in-house. A more straightforward case can be made when there are technical advantages of integration through performing an activity inhouse. For example, the companies that roll kitchen foil will first of all roll it to the required gauge (thickness) in giant rolls up to 2 m wide. They will then ‘slit’ these rolls into the widths we buy in the supermarket. Two activities which could be performed by two different companies in the supply network. Yet if it is technically feasible and convenient to slit the foil in line with the rolling process, it saves the loading and unloading activity in between rolling and slitting as well as any transportation necessary. This argument can be taken further to include not only the direct technical activities but also the indirect activities such as quality control, human resource management or financial management. Putting two sequential processes together may genuinely reduce costs (or even improve the effectiveness) of such ancillary processes. However, perhaps the most frequently deployed cost argument in favour of vertical integration is that it reduces the transaction costs of dealing with suppliers and customers. • Improvement to product and service quality – The exact specialist advantage may be anything from the ‘secret ingredient’ in fizzy drinks through to a complex technological process. In either case the argument is the same. ‘This process gives us the key identifying factor for our products and services. If anyone but ourselves performs this activity we cannot keep it to ourselves for any length of time. Vertical integration therefore is necessary to the survival of product or service uniqueness’. • Learning by owning – So, for example, Benetton, the Italian fashion garment manufacturer, although subcontracting the majority of their manufacturing processes, still do some work in-house. Some of this in-house work is devoted to core processes such as fabric dyeing (a core process which defines their products). But some of the processes will merely perform activities which are also outsourced. One reason for this is that outsourcing the whole of one activity may result in the company getting out of touch with improvements in that process and failing to learn new techniques. Similarly, McDonald’s, the restaurant chain, although largely franchising its retail operations, does own some retail outlets. How else, it argues, could it understand its retail operations so well? The disadvantages of vertical integration The chapter also cites a number of disadvantages of vertical integration. • It creates an internal monopoly – At the core of this argument is if the consequences of not maintaining or exceeding the levels of service and efficiency required by the market is that the operation goes out of business, then the motivation to remain competitive is a powerful one. Furthermore, market forces are relatively transparent. If the operation does not produce services and goods of sufficient quality, or takes too long in delivering them, or fails to keep its delivery promises, or will not change to suit customers’ requirements, or cannot profitably meet competitors’ prices, then it loses business. Customers stop placing 286 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual orders, everyone can see the lack of activity, suppliers feel less sure of their future business and owners and shareholders demand to know what is happening. Either the company improves its performance to match what is available elsewhere in the market or, alternatively, ceases to trade and the business goes to those operations that can satisfy their customers. Such incentives and sanctions do not apply if the supplying operation is part of the same company. • You can’t exploit economies of scale – The businesses to which one outsources activities are unlikely to be exclusively dedicated to one customer. This means that they can perform similar activities for many different customers and therefore achieve a higher volume of operations than any of their customers performing the same activities themselves. • It results in loss of volume flexibility – Conversely, low fixed costs (even with high variable costs) mean that the fluctuations in volume of demand have far less impact on the profitability of the operation. • It cuts you off from innovation – Depending on how it is defined, a second type of flexibility may be impaired by vertical integration: new product and service flexibility – in fact innovation generally. Vertical integration means investing in the processes and technologies necessary to produce products and services. No one likes to invest in processes which are soon overtaken by superior technologies. As soon as that investment is made the company has an inherent interest in maintaining the appropriateness of that technology. Abandoning such investments can be both economically and emotionally difficult. The temptation is always to wait until any new technology is clearly established before admitting that one’s own is obsolete. This may lead to a tendency to lag in the adoption of new technologies and ideas. Nor is it only the new technologies and ideas available in the free market to which a low vertically integrated company has the access. It is also the ideas sparked off through the company’s dialogue with customers and suppliers. There is a considerable body of evidence to suggest that. • It distracts you from core activities – The final, and arguably most powerful, argument against vertical integration concerns any organisation’s ability to be technically competent at a very wide range of activities. The argument goes something like this – One of the worst things they can do is attempt to be equally good at many other things. They can be profitable by being very good indeed at a narrow range of activities, but they find it far more difficult to be profitable by being merely reasonably good at a very wide range of activities. ‘Reasonably’ good is not sufficient protection against some other company entering the market in order to be even better. When vertical integration is appropriate? Although vertical integration is clearly an important issue, and although many research studies have been published in the area, don’t expect too much unambiguous guidance on whether vertical integration is a good thing or a bad thing. However, notwithstanding the fact that there seems to be at least some evidence to support almost every view on vertical integration, some points have emerged which command some degree of consensus. • Vertical integration is not fashionable. Far more organisations over the past 20 years have tended to de-integrate rather than integrate. Companies most frequently justify this in terms of ‘sticking to the business that they know best’. 287 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Vertical integration is easier to justify when the total of all costs incurred by all the processes integrated are reduced. (At times vertical integration has been justified by looking at savings in one part of the network only.) This is most clearly demonstrated when there are technical cost savings of integration (such as the in-line slitting mentioned earlier). • Vertical integration is generally regarded as a high-risk strategy since it means high levels of investment. If the environment in which the vertically integrated company is operating is relatively stable then the risk may be worthwhile. However, if the market is likely to undergo significant changes in its levels of activity or types of products or service produced, then vertical integration exposes the company’s lack of flexibility. • Generally vertical integration makes its difficult for a company to access the innovations which become available in the supply market. This is especially true when those innovations are autonomous (i.e. they do not depend on other innovations for their contribution to a company’s competitiveness). The case for vertical integration is stronger when innovations are systemic (i.e. an innovation in one part of the network requires innovations in other parts of the network to exploit its full contribution to competitiveness). Traditional contractual (market-based) supply Some authorities argue that two factors are particularly important in determining whether contractual mechanisms are appropriate in shaping buyer–seller relationships and in determining exactly how market mechanisms are used:2 the number of alternative suppliers in the market, and the resource cost to the buyer of changing suppliers. When the cost to the buyer of making a change in supplier is very high and anyway there are few alternative suppliers to switch to, it is unlikely that buyers would want to use pure market mechanisms. The buyer’s hand is relatively weak whereas the supplier has relatively high shortterm security. Under these circumstances it is likely that some kind of partnership agreement may be appropriate (we shall deal with partnership relationships next). Conversely, when the cost to the buyer of making a change in supplier is low and there are many alternative suppliers, leveraging the free market is probably the best way for a buyer to keep the performance of their suppliers competitive. Between these extremes the issue is less straightforward and as much concerned with how to use market mechanisms as it is whether to use market mechanisms. A key factor here is market uncertainties (we aren’t entirely sure what is available out in the supplier market) and needs uncertainties (we aren’t entirely sure what we need from the supplier market). When the cost to the buyer of making a change in supplier is low and there are few alternative suppliers, buyers have little market uncertainty. There are few alternative suppliers and it is not difficult to negotiate with them all over the subtleties and trade-offs of what and how they supply. They are willing to enter into this type of negotiation because they know that you could switch to an alternative supplier relatively easily. However, both of you know that you cannot be constantly switching suppliers. Because there are few alternative suppliers, your promiscuous behaviour soon would make you an unattractive customer. From the buyer’s point of view a sensible question to ask existing suppliers would be, ‘Given that you and other alternative suppliers are 2 Kapoor, V. and A. Gupta (1997) ‘Aggressive sourcing – a free-market approach’, Sloan Management Review, Fall. 288 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual relatively close in what you can offer, how can your company offer some combination of supply performance to me which helps me solve my problems?’ When the cost to the buyer of making a change in supplier is high and anyway there are many alternative suppliers, no buyer can have perfect knowledge of all of them so there is high market uncertainty. Also, because there are many alternative suppliers, the chances are that there is a wide range of alternative deals and supply performance levels available. Although buyers can easily find an alternative supplier, they will only do so if the gap between existing suppliers’ performance and prospective new suppliers’ performance is sufficiently high to recoup the high cost of switching. Existing suppliers know that buyers will be reluctant to switch unless the performance gap is large. Therefore negotiation is likely to centre around exploiting market uncertainty. The buyers stance could be, ‘I can easily find a better supplier but will not switch to them if you can promise to come close to matching their performance’. Partnership supply By building better supplier relationships, many of the benefits ascribed to vertical integration can be achieved without the costly recourse of large capital investment. However, good relationships and good supplier performance are neither an automatic nor even a guaranteed outcome. Care and attention to supplier selection and supplier management is required in order to gain the maximum benefits from the supply network. Supplier selection Selecting a supplier with whom we intend to have a long and profitable relationship is undoubtedly a major strategic decision. Failure to identify potential weaknesses or shortcomings can prove very costly and may be irretrievably damaging to your strategic fortunes. It is not uncommon for firms to set out their sourcing policy in terms of: • Their key or critical items of expenditure. • Their strategic aims in terms of supply network structure (number and responsibilities of suppliers; future outsourcing patterns). • Targets for cost, quality, delivery and timing performance of their supply network. • How many suppliers they want to have in their first tier. • The extent to which they intervene with second tier supplier activities. • Whether to single-source or multi-source their supplies. • The degree of autonomy and responsibility for design to confer on their key suppliers. • The level of financial commitment for tooling and equipment they wish to make with their suppliers. • How they will organise their supplier management process (e.g. multi-functionally). 289 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual For example, Hewlett Packard in the UK had a policy to single source parts, and multi-source commodities. Their reasons for single sourcing are first that it is part of the overall long-term commitment to the relationship with their suppliers. Second, it allows them to focus on selecting, developing and monitoring one source only. Finally, there are sound commercial reasons for doing so – leverage can be gained from volume in both price and service, there is greater likelihood of obtaining consistent quality levels, and any tooling investment is limited to one source. There are risks though associated with single sourcing. These include the lack of a second source when the fist source has problems, and the competitive advantage of having multiple sources. Supplier management in partnership relationships Central to the idea of partnership is the ‘closeness’ of the relationship between the partners. The chapter identify a number of factors that have been cited in the body of research in this area as being important in achieving closeness. These factors are as follows. • Trust • Sharing success • Long-term expectations • Multiple points of contact • Joint learning • Few relationships • Joint coordination of activities • Information transparency • Joint problem solving • Dedicated assets All these issues are important, partly because the capabilities of suppliers are critical to any businesses’ competitive performance, and the strategic choices we take about our operations need to take into account not only the form of internal operational capabilities, but also the manner of relationship we wish to develop and sustain within our supply network. In particular the development of mutual trust marks the degree of closeness between purchasers and suppliers. The chapter, in effect, identifies a continuum of trust, calculative trust, through cognitive trust to bonding trust. The degree of trust that exists between the two parties is important in identifying the relationship. However, the chapter categories are better known amongst academics than practitioners. A better-known categorisation is as follows: • ‘Competence’ trust, which relates specifically to the perceptions and confidence in the capability, expertise and knowledge of one party by the other. • ‘Contractual’ trust, which at its simplest level is the faith in the other party to honour the contractual obligations. 290 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • ‘Goodwill’ trust, ‘...a mutual expectation of open commitment to each other’. Trust, in any of these forms, may develop over time as a result of the experiences of both parties with each other, but it may also be affected by the reputation of one of the parties. Purchasers also conduct formal assessment and evaluation of potential and existing suppliers on a regular basis. Ford Motor Company, for example, has a long established and highly regarded Supplier Quality system, and many companies look for possession of an international accreditation such as the ISO 9000 series or Baldridge awards as indicators of supplier capability and performance. The idea of mutual learning is also important. For example, suppose a retail bank has a partnership agreement with a credit agency which gives credit risk assessments of the bank’s customers who are applying for loans. Whereas the bank would not wish to carry all the information which would enable it to judge the loan applicants themselves, it can do more than merely wait until the credit agency pronounces on the applicants’ credit worthiness. In discussions with the credit agency it may be able to improve the questions it asks of applicants, and it may also be able to screen out certain applicants at an earlier stage of the application process. It is therefore learning how to deploy the credit agency’s services (preferably) to both their advantages. Similarly, the credit agency might wish to further refine its decision-making processes in consultation with the bank’s experiences of which customers were indeed credit worthy. In this way the partners learn from each other to their joint advantage. Similarly the idea of limiting relationships to a relatively few is central to developing partnerships. Of course, sometimes customers are obliged to source products or services from more than one supplier. A single supplier may not be able to fulfil volume, location, or variety requirements. Similarly, a single customer, no matter how close, may not be able to take sufficient volume to make exclusive relationships economic. However, it is worth stressing that the recent general move towards having fewer suppliers is related to the general desire to develop closer relationships with those which remain. Supply network dynamics Network behaviour is concerned with the dynamics of how supply networks actually perform in practice. The chapter classifies the underlying causes of supply chain behaviour in terms of their • quantitative dynamics, and • qualitative dynamics. Quantitative supply chain dynamics One of the most important issues in supply network behaviour is what The chapter call the quantitative dynamics of the way supply networks operate. Central to this idea is the so-called ‘bull-whip’ effect. This is illustrated in Chapter 5 by using a four-stage supply chain. Although not specified, this example is clearly a manufacturing supply chain in so much as it transfers physical items between stages. However, the bull-whip effect also applies in non-manufacturing chains. Here, it is not so much the inventory between stages and the lag between placing orders and receiving orders that causes progressive amplification down the chain; rather it is the fluctuation in capacity at each stage. The chapter’s example assumes that there is no constraint on capacity and that each stage can produce as many as its customer demands. This is clearly a 291 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual simplification, especially in service chains where they may be a significant lag between the capacity being required and it coming on stream. Yet the net result is broadly the same whether we are dealing with physical items moving between stages in the supply chain or less tangible ‘service’ moving between the stages. Qualitative supply chain dynamics The essence of supply network management is that operations can derive some advantage from examining, understanding and influencing the other operations in the network of which they are a part. It is the degree of influence that managers have over the resources that create their products and services is, to some extent, a function of how close the resources are. If they are located, say, in another division of the business, they will be managed (partly) in the interests of that division, which may not totally coincide with other parts of the business. If the resources are in a supplier’s or customer’s business, influencing the resources is even more difficult. The resources in customers’ customers and suppliers’ suppliers are several degrees more difficult to influence. Yet, if the other operations in the network are to be influenced, an essential prerequisite is that we understand the way in which they influence, and are influenced by, the dynamics of the network. The chapter discusses the dynamic behaviour of supply chains. Their discussion includes the ‘Bull-whip’ effect. This is an important ‘natural’ characteristic of supply chains and is often discussed in academic and practitioner books on the subject. What is very rarely mentioned is what The chapter call qualitative behaviour. They use a little known model derived originally by Harland as a basis for looking at how the ‘non-physical’ flow of operations performance can become distorted or misaligned along a supply chain. The following figure replaces the original Harland terminology with more ‘user friendly’ terms. The ‘perception gap’ model of qualitative dynamics The gap model described by The chapter is a particularly useful diagnostic for any organisation wishing to examine critically its supply network performance. In effect, it is asking businesses to be honest in assessing not only how they see a relationship but how they believe their customers and suppliers perceive the relationship. In doing so it identifies some important potential gaps. These are as follows. • The supplier improvement gap is that between what a customer believes its needs and what it sees itself as getting from its supplier. This is the most serious of the potential mismatches if the customer’s perception of its supplier’s performance falls below what it believes its own requirements to be. • The market perception gap is essentially a gap between the perception of what a supplier believes its customer wants and what its customer really does believe it wants. It is a market positioning mismatch, which could occur because of a lack of understanding between A’s sales and marketing function and B’s purchasing function. • The operations performance gap is the gap between a supplier’s view of its own performance and how its customers view its performance. A may believe that it is performing well enough while B, in reality, is either wanting different things from its supplier or, alternatively, has different standards against which it is assessing A’s performance. 292 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • The operations improvement gap shows how a supplier rates its own performance against what it believes its customer to want. Significant gaps here should be driving the suppliers’ own operations improvement programs. When extended to a supply chain, as opposed to a simple customer–supplier pairing, two further linkages are worth considering. These are shown on the diagram as ‘supply choice’ and ‘supply development’. • The ‘supply choice’ association is the link which an operation makes between how it is served by its supplier and what it believes its own customer wants. A strong association means that the supply relationships significantly affect an operation’s ability to serve its customers. It is a measure of the degree of fit between its supply strategy and its overall operations strategy. • The ‘supply development’ association is the link between how an operation is, in reality, served by its supplier and how it is capable of serving its own customer. It is a measure of the extent to which an operation’s competitive success or failure can be explained by its supplier’s performance. It also dictates the approach an operation could take to developing its supply strategy. Of course, one could extend this type of analysis to look further into suppliers and customers. So, for example, it may be useful to understand the supplier improvement gap in the customer’s operation. That, after all, will be shaping their view of us as a supplier. Similarly, one might investigate the operations performance gap in a supplier. This would tell us the extent to which problems with supply are a result of their operations failure rather than requirement or performance misunderstandings. And every time there is a gap between the perceptions of customers and suppliers, and every time there is a failure within an operation to understand the associations between its supply side and demand side requirements and performance, information is distorted. This distortion can lead to operations developing their resources inappropriately. Investments may be made, systems and processes designed, and operations strategies formed which inhibit the effective integration of the operation within its network. In fact one can view the cumulative effect of these gaps up and down a supply chain as being the qualitative equivalent of the bull-whip effect discussed earlier. Mistaken perceptions in any part of the chain can become amplified as they are further distorted by the mis-communications and perception gaps between other operations in the chain. Managing suppliers over time By ‘managing suppliers over time’ the chapter means the way in which supply networks can be managed in order to ensure effective operation and improve overall network performance. What happens when the supply network manages you? An implicit assumption running through the chapter’s discussion of supply network management (and one that is almost universal in all writings on supply networks) is that the customer holds the balance of power in the buyer–supplier relationship. This power is assumed to be held unilaterally, and allows the customer to influence suppliers who will be willing to 293 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual conform to their requirements. Yet, in reality this is not always the case, for example when a customer is significantly smaller than a supplier and when the business represents a small proportion of the supplier’s sales, but a large proportion of the customer’s costs. What then is the likelihood that a customer can ‘manage’ their immediate suppliers? The balance of power is firmly with the supplier and the company may be more managed by, than managing, its supply chain. Some small companies, especially those making low-tech, highly standardised products, may never find themselves in a position of having much leverage with their large suppliers. Their only option, maybe, is to multi-source because in such scenarios, supplier loyalty cannot be guaranteed. However, many small companies have unrealised sources of strength. They may be able to trade with something other than money. They may have process or market knowledge which itself is valuable to their suppliers. By developing and deploying core competencies such as technological or market know-how, powerful suppliers may be willing to invest in the relationship, even when it is not a large proportion of their sales. Example Company X manufactures assay and analysis machines for the examination of soil samples. These machines almost always involve the use of radioactive sources. These radioactive sources are the key component of most of the company’s products and are bought from two or three large companies. Although small, Company X is a typical customer for the radioactive source suppliers who, despite having some large customers, sell more than 75 per cent of their products to small customers not much larger than Company X. Frustrated by the difficulty in gaining their radioactive source suppliers’ attention, Company X launched two initiatives. The first involved exploring ways in which the radioactive sources could be used more effectively within their own product designs. The second involved surveying their own customers (mainly mineral exploration companies and laboratories) in order to determine likely future trends in their market. The results from both of these initiatives were made available to the most receptive of their radioactive source suppliers. ‘In effect we said to them, look, we can offer you two invaluable pieces of knowledge. First, we can tell you how you could modify your products to be better for your small customers, especially those in similar fields to ours. Of course there was a risk in that for us, but we figured that, even though our competitors might get this knowledge, we could always keep ahead of them in terms of how that knowledge could be deployed. Second, we said to them, your business depends on your customers’ customers. They are our immediate customers. We have taken the trouble to get to know them very well indeed. Therefore we can jointly develop a model of how the industry could develop in the future. We offered ourselves up as valuable “knowledge partners” to them in developing our joint business. We were saying to them, hey, you can get real competitive advantage by working in partnership with us’. Fisher’s Model One of the most influential supply network strategy models to emerge over the last few years is summarised in Figure 5.3. This so-called ‘Fisher model’ seeks to discriminate between different market-based objectives and recommend varying supply network management policies for different market objectives. In his original article Fisher poses some interesting notions about the strategic performance of the supply network. The importance of this article is that the approach he advocates mirrors our perspective on operations strategy, namely: 294 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Make a choice about what you need to do to compete with your products and services. Set about matching the resources and processes in the supply network with the strategic choices you have made. Fisher also cites the case of Campbell Soup, who improved the speed and dependability of supply to their retail customers by highlighting the disruptive (and unprofitable) implications of certain price promotions. The contrast between a marketing strategy aimed at boosting the volume of a particular flavour of soup, and the impact upon their supply network performance was quite startling. By adopting a different pricing strategy, Campbell Soup was able to give the retailer a better return on purchases, and the manufacturing and distribution elements of their network were able to improve their operating efficiency and effectiveness – a ‘win-win’ situation that keeps all parties happy! The important issue here, however, is that the different types of markets will need serving in different ways by their supply chains. However, useful though this kind of analysis is, the Fisher model does it imply that market requirements are either predominantly functional or predominantly innovative? Furthermore it avoids the question of whether supply chains can be organised to mix responsiveness and efficiency in different proportions, or should they be designed to be one or the other? Whatever the answer to the question, what if a company has a mix of products, some of which are functional and others innovative? Can both of these products be moved down the same supply chain? If so, is that supply chain a compromise between responsiveness and efficiency, or does one give different products different priorities? Alternatively, does it imply that separate supply chains are necessary for different types of product? As a further illustration of how market objectives influence supply strategy, Figure 5.2 illustrates two supply networks, structurally identical, but managed in different ways. The top network is designed for low cost. Inventories are kept low, especially in the downstream parts of the network, so as to maintain fast throughput and low working capital. The inventory in the network is concentrated primarily in the manufacturing operation, where it can help to keep utilisation high and manufacturing costs low. The predominant flow of products and information occurs up and down the chain. Information must flow quickly from the outlets to the manufacturer and supplier so that their schedules can be given the maximum amount of time to adjust efficiently. Products then flow as quickly as possible down the chain to replenish what little stocks are kept in the downstream outlets. By contrast, the lower network is organised for high service levels and responsive supply to the end customer. The inventory in the network is deployed as close to the customer as possible, so as to cope with what may be dramatic changes in customer demand. Of course, fast throughput from the upstream parts of the network is still needed to replenish the downstream stocks, but it would not be sufficient in itself to give a high enough level of end customer availability. Again, although products and information will flow up and down the network, it is also important to ensure flow across the downstream part of the network. So, for example, if stock-outs occur in one of the outlets it may be faster to transfer product from other outlets to where it is needed. This is why some retail stores invest in information systems which allow them to check whether one location has a product in stock which another location has temporarily run out of. 295 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Reconfiguring networks As an example of how the linkages in a supply network could be changed, consider Figure 5.3. A manufacturing operation which has three plants is supplying eight customers. In the arrangement in Figure 5.3(a) each plant supplies each customer. This means that in total there are four routes (24 links between each pair of plant and customer). Each plant must have separate lines of communication with all eight customers and each customer will need to communicate directly with each of three plants. Now consider the second arrangement in Figure 5.3(b). Two regional warehouses have been imposed between the plants and the customers. The three plants now distribute their products to the two regional warehouses from which their local customers are supplied. There are still 24 routes but simplified by using only six plant–warehouse and eight warehouse–customer links. More significantly, each plant now has to deal directly with only two immediate demand-side links for its products instead of the previous eight. Similarly, each customer now has to deal with only one supplier (its local warehouse) instead of three as previously. Figure 5.3(c) simplifies the linkages even further, but it does this by transferring complexity to the plants themselves. Whereas, in the previous two network structures, each plant concentrated on one set of activities, this final design requires each plant to widen the scope of its activities so as to be able to serve the total needs of its customers. 296 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual 297 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 6 Process technology strategy Chapter aims This chapter is not concerned with the detailed description of any actual technologies as such. Rather it is concerned with the strategic impact of process technologies – an impact that can be very significant. Whether it is advanced manufacturing technologies in manufacturing or pointof-sale systems in retailing or advanced optical reading equipment in banking, process technology can provide profound advantages in almost any industry. However, there have also been some spectacular failures resulting from the introduction of new process technologies. This is why this topic is so important; a failure to understand the implications of a new technology or a badly implemented technology can destroy all the potential benefits of technological innovation. This chapter aims to: • Explore the nature of ‘process’ technology strategy • Identify the characteristics of process technology and how they need to be adapted for new information technologies • Describe the ‘product-process’ matrix, in which market volume and variety can be shown to influence process technology • Discuss the strategic evaluation of process technology Process technology strategy Technology strategy is ‘the set of decisions that define the strategic role that direct and indirect process technology can play in the overall operations strategy of the organisation and sets out the general characteristics that help to evaluate alternative technologies’. It also points out the central role of operations in articulating how technology can improve operational effectiveness and acting as an ‘impresario’ for implementation. Not that operations managers should be experts in the core science behind the technology, but they should be able to ask relevant questions such as the following: • What does the technology do that is different from other similar technologies? • How does it do it? • What constraint does using the technology place on the operation? 298 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • What skills will be required from the operations staff in order to install, operate and maintain the technology? • What capacity does each unit of technology have? • What is the expected useful lifetime of the technology? The following example gives the flavour of how technology impacts operations and how these questions can be used. Into Oblivion After more than a year of secret development, the summer of 1998 saw Alton Towers Theme Park in Staffordshire, England (owned by Tussaud’s Group), unveil what had become known throughout the industry as their Secret Weapon 4 (SW4). This ride – called Oblivion – was the world’s first vertical drop roller coaster. The ride was designed and manufactured in Switzerland by the specialist roller-coaster design firm, Bolliger and Mabillard. The firm from Monthey, Switzerland, was founded in 1988 and has a reputation for innovation. In 1992, for example, they invented – at the Six Flags Great America park in Gurnee, Illinois – the world’s first suspended coaster where people’s feet actually hang down below them during the ride. SW4 was demonstrated initially to journalists and ride enthusiasts (who, on the Web, had been speculating for a long time about what SW4 might be). This level of speculation was actively encouraged and, before launch day, Oblivion was the subject of an intensive marketing campaign that sought to tease customers about the exact nature of the ‘entertainment’ that awaited them. ‘Taking the plunge in a way never experienced before are passengers test-riding the world’s first roller coaster with a vertical drop. Passengers on the 160-s ride endure a four-second pause dangling face-first over a dark tunnel before dropping 200 ft into it at 70 mph … moving rapidly from light to dark will induce the same sort of disorientation as jet pilots experience. By the end of the ride, passengers’ pulse rates will have soared to about 180 beats per minute – the equivalent of a hard workout’. The ride has proved to be extremely successful. Alton Towers is open for only 8 months of the year, yet Oblivion manages to throughput approximately 3.5 million passengers in that time. Despite the relatively short length of the ride, this popularity inevitably created major queuing issues. Therefore, in addition to the physical processing technology challenges of the ride, there was also a need to develop active queue entertainment systems. There are different themed stages – the four stages of Oblivion – to the process, each involving a different video presentation. In stage one, participants are told about the physical effects the ride may have on their bodies, including a suggestion that it may make your skull rattle! Stage two encourages people to consider whether they can cope and stage three links messages such as ‘is this really entertainment?’ with answers like ‘it’s just a ride’. As the riders are strapped in to the train, they hear the fourth-stage message, ‘Welcome to Oblivion, there is no reason, and there is no rationale’. Pragmatically, the Alton Towers marketing manager explains it thus: ‘It’s basically to get people excited in the queue … we really want to make the entertainment last longer than the ride’. This example illustrates many of the challenges that process technology created for all types of operations. For instance, the Alton Towers management had to answer a series of technical questions, such as: 299 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual What does the technology do that is different from other similar technologies? Does the technology provide capabilities that have hitherto been difficult to obtain? In the theme park market, most customers will make only one visit per year (a typical ticket costing upwards of $50) and they have an increasing variety of choices. A widely acknowledged reputation for ‘uniqueness’, is therefore a very valuable competitive attribute. Oblivion was the first vertical drop ride and comprised a number of unique technical elements. For instance, the nature of the ride necessitated a very complex lifting system, using four separate conveyor systems. How does it do it? That is, what particular characteristics of the technology are used to perform its function? Looking at the lifting system, for instance, the first vertical conveyor is the lift mechanism (much stronger than a normal coaster chain) that lifts the train to the apex of the track; a horizontal conveyor then takes the train to the drop point where it engages with the drop conveyor. This vertical conveyor takes the train slightly over the edge of the drop crown and puts it into a holding position that helps to maximise the passenger’s ride sensation. After a suitably ‘tantalising’ period, this conveyor accelerates away and effectively allows the train ‘to drop’. The final horizontal conveyor picks up the train after its braking run and takes it to the loading/unloading station’s control systems. What constraint does using the technology place on the operation? Very few firms manufacture their own process technology and often they have little input to the design process beyond the setting of the original concept. The management of the supply-chain aspect of process technology development has a major influence upon eventual technical and competitive success or failure. Although there were one or two delays in the development of the ride, in this case the relationship with Bolliger and Mabillard seems to have been successful. Ultimately, however, rivals can now hire the firm to create something equivalent (or more likely, even better) for themselves. What skills will be required from the operations staff in order to install, operate and maintain the technology? Although the physical manifestation of the technology may be its metal frame, hydraulic devices, rotating mechanisms, etc., often this does not represent its most critical or complex aspect. For Oblivion, there is a software system that links together all the different elements and controls their interactions. The ride operator has a very different role, therefore (not like a classic fairground operator who physically spins the carriage on a ride). He or she is a monitor of system performance whose intervention is rarely, if ever, needed. What capacity does each unit of technology have? There may be a choice between employing several small units of process technology, or one large-scale unit of technology. The unique nature of the technology means that it has a ‘natural scale’ defined largely by the technical characteristics of the ride (its vertical drop, track and car size, etc.), and therefore effective capacity management (i.e. high utilisation of a single unit) was a key challenge for Oblivion. In order to maximise the throughput of riders on the roller coaster (1950 per hour in this case) multiple trains were required to be on the track at any one time. However, given that this ride is much shorter than a traditional one, this requirement necessitated yet further innovative process solutions. The ride’s designer explained how they achieved this by ‘loading and unloading two trains at once … one train will be on the lift hill, and another ready to drop. One train will be at the start of the brakes. The other two will be sitting outside the station waiting to come in and unload’. What is the expected useful lifetime of the technology? Will its technical performance deteriorate over time? How easy will it be for the technology to be upgraded in line with future technological developments? In a competitive market, ‘uniqueness’ is clearly an invaluable competitive attribute but it is one that is very difficult to sustain, especially as rivals can quickly 300 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual observe the technology or, in this case, commission the same firm of design engineers who created the original. The functionality of the technology will not deteriorate in the short term (although health and safety requirements will necessitate regular maintenance and eventual refit) but as vertical rides become commonplace and other parks offer longer and scarier drops, the relative performance of the technology will diminish. The combined effect of the competitive dynamic, the one-off nature of the ride and the service context it operates in means that little, if any, consideration was given to potential upgrades for the technology as it dates over time. Understanding the different types of technology The chapter uses a definition for technology based on one from Zanussi – the appliance of science. So… process technology is the appliance of science to any operations processes. But, what exactly is meant by the term ‘process technology’. Process technology versus product/service technology This is one of those distinctions that it is important to understand yet which is not, in itself, a clear and clean distinction. Direct process technology directly helps to create the service or product whereas indirect process technology helps to manage the process that creates the service or product. It is a relatively simple distinction to understand in manufacturing operations. So, a business manufacturing specialised and customised communication electronics may compete through its high-performance products using advanced product technology. The process technology that is used to manufacture these products will probably be general purpose and capable of making whatever products are designed. In this case the operation’s product and process technologies will be relatively independent. Other (even manufacturing) operations will have a stronger association between the development of the operation’s product and process technologies. For example, an ice-cream manufacturer will use process technology that has been developed to make ‘frozen semi-liquid’ products and could not make any other type of products very effectively. However, in service operations it is more difficult to distinguish process from product/service technology because customers very often have direct experience of the technology. A chain of cinemas, for example, may be investing in digital projection technology and by doing so is investing in both product and process technology simultaneously. As a further example of this distinction consider the legal industry. Because lawyers consider themselves part of the ‘professional service’ industry does not mean that they cannot gain benefit by using process technology. The fact that lawyers ‘process’ knowledge (and clients) means that technology can help them store, analyse and manipulate this knowledge (and these clients). Some of this technology is known as ‘litigation support’ technology. These enable lawyers and clients to access databases, sometimes via the Internet, containing previous legal judgments. Such databases are designed to help law firms capture, share and recycle their accumulated collective experience. Search engines can help them search ‘practice area libraries’ to obtain access to different types of legal information. By contrast, the indirect process technologies used by legal firms are less client facing and more back-office oriented. These systems concentrate on scheduling work, controlling activities within the firm and ensuring the efficiency and dependability of the delivered service. Remember though that some technologies can cross this direct/indirect divide. Some newer process technologies used in the legal industry are built around systems that can help clients directly to help track the progress of the work 301 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual being undertaken for them and even answer questions and take part in the processing themselves. It is also worth remembering that one company’s process technology is another company’s product technology. The processing equipment in a food factory, or in a call centre, is clearly its process technology. Yet, for the companies that manufactured that equipment, it is their product technology. In fact, increasingly, product and process technologies are merging. Look at Google, one of the most successful internet-based companies in the world, which in a few years has moved from being the provider of a particularly effective search engine, to being one of the most active players in providing internet-based services. Google is a company that is its process technology. Google is offering its process technology to a whole community of internet users and advertisers (which is almost all of us; hence the company’s spectacular growth). Its product is its process. Behind the scenes, Google spends millions of dollars on developing its processes. Without investment in understanding the future directions of both technology and markets, and without a very significant investment in the right kind of staff, its process technology, and therefore its business model, would not be as successful. The product/process innovation life cycle The idea that the life cycles of product and process technologies differ is based on research that investigated the competitive dynamics of a number of different manufacturing industries.1 These ‘life cycles’ indicated the relative importance of product or process technology over time. For example, an innovative new product enters (usually) a fragmented market and, will not be mass manufactured because of low and uncertain volumes. However, because it is innovative, some considerable effort will have been devoted to the product’s technology. As the product becomes established, dominant designs emerge and competitors force products to become increasingly commodity like. Therefore, cost minimisation becomes critical and the role of process innovation becomes more significant. Product and process innovation cycles are shown in Figure 6.1. Not all firms will have the same relationship between product and process technology life cycles. For assembled products the relationship is as shown in Figure 6.1(a). Yet, Intel will not separate the development of a new generation of chip from their ability to manufacture it, nor will most chemical and pharmaceutical manufacturers drive new products from the development of new production processes. Here the relationship will be more like that in Figure 6.1(b). For many service businesses the product/process distinction is even more difficult to conceptualise. The key technological considerations are inevitably those that relate to process because the process is itself the service; these ‘product’ and process life cycles become the same thing as in Figure 6.1(c). 1 Abanathy, W.J. and J. Utterback (1975) ‘Dynamic model of product and process innovation’, Omega, Vol. 3, No. 6. 302 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Direct and indirect process technology The chapter also distinguishes between two types of process technology. The first contributes ‘directly’ to the production of goods and services, for example robots welding body panels or sorting machines processing mail. The second type of process technology (one receiving increasingly significant investment) is the ‘indirect’ or ‘infrastructural’ technology that acts to support core transformation processes. Both manufacturing and service operations are increasingly reliant upon ‘indirect’ process technology (and investing more in indirect technologies). These are defined by the chapter as ‘infrastructural and information technologies that help control and coordinate direct processes’. Put another way, indirect (or supporting) process technology is the ‘appliance of science to the processes which provide or support the infrastructure for those processes which directly contribute to the production and delivery of products and services’. Indirect technology includes such things as supply chain management systems, stock control systems, yield planning and pricing systems, information databases, Enterprise Resource Planning (ERP) systems and the scheduling systems that plan transport routes and staff rostering for mail delivery and so on. Figure 6.2 illustrates this idea. 303 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Again, remember that one operation’s indirect process technology can be another operation’s direct process technology. So, a business may invest in a customer relationship management system to help it offer more appropriate services to its customers. This is an important indirect process technology to the business. However, alternatively, it may engage the services of a specialist agency that offers customer analysis services using exactly the same technology. But to this agency the technology is very much a direct process technology because it directly provides services to the agency’s customers. In other words, the overall purpose of this direct process technology is to produce products and services for an operation’s external customers. Material, information and customer processing technology An alternative classification of process technology is based on the main input that is processed by the technology. They can be either materials processing (as in manufacturing operations), information processing (as in financial services, for example) or customer processing (as in retail, medical, hotel, transport operations, etc.). A shortened list of example technologies used in Chapter 6 of the text is shown in Table 6.1 also classified as direct or indirect. Note how indirect process technology is confined to information processing. Table 6.1 Some process technologies classified by their primary inputs and their direct or indirect role Direct or indirect? Direct process technologies Material processing technologies Flexible manufacturing systems (FMS) Weaving machines Automatic vending machines Information processing technologies Optical character recognition machines Online financial information systems Customer processing technologies Surgical equipment Milking machines Medical diagnostic equipment Body scanners Aircraft Container handling equipment Mass Rapid Transport (MRT) systems Automatic warehouse facilities Renal dialysis systems Theme park rides Indirect process technologies Management information systems Search engines on the Internet Telecommunication technologies Archive storage systems Global positioning systems 304 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The characteristics of process technology The chapter uses three underlying characteristics of process technology. • The scale or scalability of the technology (in capacity terms – not physical size). • The degree of automation or analytical content embodied in the process technology. • The degree of coupling or connectivity of the technology. These three characteristics are strongly related. For example, at the small scale, manual, uncoupled and flexible end of the technology spectrum (the manufacturing job-shop or professional service firm), flows will be intermittent, loading in the different parts of the operation will vary almost every hour. The progress of work through the system could be almost anywhere and so have to be monitored and controlled. At the other end of these dimensions, technology is large, automated, integrated and less flexible (a steel production line or an automated cheque-processing unit). Any miscalculations in the choice of technology will be extremely difficult to overcome because once the operation is committed to the capacity and nature of this structure; most subsequent changes will require (often substantial) capital expenditure. Scale/scalability The first of the three underlying characteristics is that of scale or scalability, an issue that is very closely aligned to the ideas of scale discussed in Chapter 3 on capacity strategy. Broadly speaking, some technologies benefit from economies of scale while others find it difficult to do so. Some process technologies that are deployed in commodity industries like cement manufacture or petrochemicals often benefit from scale and therefore tend to come in large capacity increments. Other technologies have a ‘natural scale’ that is much smaller. In some theme-park rides, making the cars that carry customers any bigger could be technically difficult. Example – Micro-power2 Big is no longer beautiful in the world of power generation. Traditionally, economies of scale have ruled in the construction of power stations. Generating electricity meant burning fossil fuels to drive giant turbines that produced electricity. Not many years ago, giant plants burnt coal and produced 2,000 MW (megawatts) of electricity. Even smaller nuclear plants were built to produce 1,000 MW. But technological development, market pressures and environmental concerns have acted together to change the whole outlook of the industry. Now a plant producing only 100 MW is seen as too expensive, too risky and needing too long to construct. In June 2000, ABB (the global technology company) launched its ‘Alternative Energy Solutions’ programme. The company, which had recently sold its business making large-scale power plants, had begun to concentrate on making small 10 MW systems, the consumption of a fairly large factory. 2 Boyle, S. and C. Henderson (2000) ‘Small scale is beautiful’, Financial Times, 10 August; The Economist (2000) ‘The Dawn of micro-power’, 5 August. 305 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Behind this move was a belief by ABB that there would be a general move from large centralised power plants, whose energy was distributed through grids around a large region, to ‘virtual utilities’ that can link small-scale power plants serving individual operations. The future of electricity generation could be one involving large numbers of individual operations. Offices, or even houses, could each generate small amounts of electricity, perhaps using new technologies such as fuel cells housed in units no larger than an average domestic heating boiler. ‘Net metering’ would allow any surplus energy generated to be sold into the electricity grid, with electricity being taken off the grid in the conventional way when local consumption exceeded generation capacity. In effect, the electricity meter would run backwards or forwards depending on whether electricity was being bought or sold. Ironically, the first person to have this vision was Thomas Edison. More than a hundred years ago, he imagined a world of connected, flexible and decentralised power plants in all large homes and offices. Increasingly, where the technology in question is ‘information rich’, scale is being replaced by scalability. If technologies can be easily and conveniently brought together to provide extra capacity when required, the scale of any individual piece of technology becomes less important. Of course, scalability requires a high degree of standardisation and compatibly. Not only is this not always possible, it also has some disadvantages. Highly standardised technologies can be relatively inflexible in the long term. Changing the characteristics of one piece of technology may make it less compatible with the other pieces of technology and therefore difficult to be combined in order to provide increased scale. Automation / analytical content The idea of automation is, in principle, relatively straightforward to understand. It simply means substituting technology in place of human judgement. This has long been a well-understood concept in material processing technologies. Machines find it easier to do relatively simple tasks but more difficult to perform tasks involving discretion and judgement. Yet, the borderline between what machines find easy to do and what they find difficult to do is for ever moving towards automation being increasingly feasible in a wider range of activities. At the same time the strong drive towards greater automation in both manufacturing and service operations is largely related to this desire to operate faster and/or deliver reduced direct labour costs. However, the true impact of automation needs to be assessed in broader terms. But, the term ‘automation’ is not always relevant when the technology has the function of replacing human decision-making. What is important is the extent to which the technology can take responsibility for the analytical content of the decision. This means that although, at a first level of analysis, information technology applications may seem to have fully replaced human intervention with technology-based decision making, there is still a range of ‘analytical content’ embedded within the technology. For example, an investment bank will use a very wide range of information technologies. However, these will vary from relatively simple and standardised spreadsheet applications that do very little other than perform very basic calculations, right through to highly sophisticated market trading systems that react in micro-seconds to market movements and continually learn from the results of their interventions. So, even in newer technologies there is still a continuum that runs from relatively unsophisticated technologies through to highly sophisticated systems that react faster and more effectively than humans. 306 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – Will computers eventually do everything? Be careful with this example. It is not meant to imply that the abilities of technology (especially new technologies) are overrated. Nor is it a reaction against increasing technological dependence. All it is saying is that there will always be some kind of frontier that represents the boundary between what technology can achieve and what it cannot. Admittedly this frontier is forever expanding but it is always likely to be there in some form or at some point. Moreover, there may be certain types of activity that can never be performed by anyone other than human beings. In fact, it is a rather reassuring message. The example is saying that we are never going to be totally replaced by machines but we can have fun pushing forward technological frontiers. Coupling / connectivity Coupling is the extent to which different items of technology can interact with each other. This may mean the ability to physically connect material processing technologies using materials handing technologies. It may mean using similar screen layouts for B2C website screen so that customers are not confused when moving between screens, or it may mean the use of common databases and common protocols so that IT systems can talk to each other. In fact, the term ‘coupling’ is best replaced by the term ‘connectivity’ in IT-based technologies. Also, the traditional rigidity of tightly integrated physical technologies are overcome by technologies that can easily communicate with each other because of their connectivity. The benefits of such highly coupled or connected technologies are usually derived from their ability to leverage their compatibility (so that delays between activities are minimised) and increase their ability to coordinate (so that activities can be synchronised or brought together in some way). However, the wider the variety or range of activities that an operation has to perform, the more difficult it is to achieve coupling (and sometimes connectivity). Compatibility is usually easier to achieve when there is some predictability or standardisation in products or services being processed. So, for example, a health care operation will perform a series of tests and measurements on patients to screen them for a common problem such as their risk of suffering heart disease. The readings from such tests may even be merged together into a formula that predicts the likelihood of heart disease. However, for a patient displaying symptoms for which the cause is not obvious, the various tests and measurements performed on them will be carried out separately and brought together to help the diagnosis of the clinical team. Example – Ditching the pipes3 Look at any processing plant in the chemical industry and you will see miles of pipes: pipes that move chemicals from one process to another, pipes that carry away excess heat from the processes and pipes that connect pumps, valves, centrifuges and so on. In fact, over 75 per cent of the capital cost of a conventional process plant goes into the structural work and plumbing that connects what are known as ‘unit operations’ together. These unit operations are the separate processes such as filtration, distillation and evaporation that are the building blocks of most chemical processing. Recently though, a new philosophy has intruded into the 3 Swan, R. (2000) ‘Engineers face new challenges and tough contracts’, Financial Times, 3 July. 307 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual conventional world of process plant design. This is called process intensification (PI). Although the idea has been around for more than 20 years, it is now having an impact in the design of process technology in the chemical industry. It attempts to make plants dramatically smaller and harder-working by designing equipment that will increase coupling by performing two or more hitherto separate activities in the same unit of technology. Using PI condensation, distillation and re-boiling can all happen in the same piece of equipment, a reactor can also act as a heat exchanger and so on. It all has the effect of making process technology smaller and reducing overall costs. In this way chemical plants, always regarded as being tightly coupled, have extended their integration to the extent that once-separate processes are now fully merged together. The product-process matrix The main purpose of the product/process matrix is to demonstrate two points. The first is that there is a ‘natural diagonal’ or line of fit between the product or service offerings that a company has and the characteristics of its process technologies. Companies may move their position on this line of fit, often moving down the diagonal as they progress along the product/service life cycle, or choose to concentrate on inhabiting one particular position on the diagonal. The second point is that any deviation away from the natural line of fit has cost consequences. If technologies are too small, labour intensive and uncoupled for the volume and variety of products and services produced, then the costs of making those products and services will be higher than they could be using more appropriate technologies. Conversely, if the technologies are too large, capital intensive and integrated for the volume and variety of products and services produced, then the technology will be too rigid, which itself produces extra costs and/or lost opportunities. The product-process matrix was first described by Hayes and Wheelwright4 in 1979. They took the product life cycle concept and linked it to process choice. Their original notion was that as a product passes through the four different life cycle stages (start-up, growth, maturity and decline) a business can select the ‘correct’ process for the particular product by considering both volume and variety characteristics. For example, whilst a product is exhibiting the low volumes associated with start-up, it is likely that the jobbing or batch mode of manufacture will be most suitable. As volumes increase, production could be switched to mass or even continuous processes. Companies who have products or service at different points on the product life cycle often choose to separate their operations according to the volume characteristics they must cope with. Commentary on example – Voucher processing in retail banking This is the story of how technology in one industry (retail banking) has moved down the diagonal of the product/process matrix. The question it does not address is, ‘What happens next?’ Perhaps the answer lies in the way the natural diagonal of the product/process matrix is being pushed outwards towards the top right-hand corner of the matrix. This is a point that will be dealt with later in this lesson. When you come to that point in the lesson think about how a greater integration of banking IT allows the bank’s back-office centres to be connected so that flexibility is enhanced and costs reduced. 4 Hayes, R.H. and S.C. Wheelwright (1979) 'Link Manufacturing Process and Product Life Cycles', Harvard Business Review, pp. 133–140, Jan-Feb 308 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Example – Learning from being ‘off the diagonal’ Moving away from the ‘natural’ diagonal usually proves costly but can also provide learning opportunities for any operation having to cope with the resulting problems. Consider the following story about a traditional manufacturer of hand tools, for example. The firm received repeated requests from their main customers (out-of-town DIY superstores) for a rationalisation of their product offering. This led them to revise their screwdriver range, replacing some 50 separate types with a newly designed (and better branded) set of 9. The original range was manufactured in batches in a number of stand-alone processes that cropped steel bar, forged the end, trimmed, heat treated, ground, sometimes plated, marked and inserted the blades into the handles; set of process technologies that were small scale, fairly manual, not integrated and very flexible. The narrow product range prompted the company’s production engineers to draw up plans for a new production system that integrated several of the operations in the original process sequence. This involved investing in rotary forging, large bed grinders and induction coil heat treatment – as well as materials-handling technology. There would be more capital equipment, fewer people, larger machines and less changeover flexibility. However, a delay in gaining approval for the capital cost resulted in the new product range being made on the old, flexible but inefficient process. Initially this seemed as if it meant redundant flexibility and high costs. The operation had not moved down the technology dimensions, yet the product profile had moved to the right. But rather than accept cost disadvantages as an inevitable consequence of having inappropriate technology, the company actively tried to exploit the advantages that their position gave them. For example, the old flexible technology could manufacture smaller batches than seemed to be warranted. But by issuing forecasts weekly rather than monthly as before, production schedules could be accommodated that matched demand much more closely and gave lower finished goods inventory. The old system was being exploited to improve responsiveness and thus reduce working capital requirements. Admittedly, total manufacturing costs were higher than would have been the case with the new technology, but not as high as they would have been without the changes to the forecasting and scheduling procedures. Eventually, the new technology superseded the old, but not quite as originally conceived. The company had become impressed with the benefits of a flexible, responsive operation. They were unwilling to sacrifice their changeover flexibility for a more automated, higher production rate, process. Consequently, several changes were built into the new integrated system to allow the same responsiveness as before. In some ways the new system was still less flexible than the old (9 types instead of 50), but not where it mattered. There are clear lessons here. Although the product–process matrix can give us a general indication of how process technology should/will differ for different product profiles, it does not prescribe a ‘correct’ technology. It gives a general idea of how technology will need to be adapted as product profiles change, but this does not preclude breaking the connection between the dimensions of technology so as to get some of the best of all worlds. Any company finding itself off the diagonal could usefully ask how it could exploit the benefits that its position gives it, and what it must do to overcome the negative effects of its position. 309 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Evaluating process technology A straightforward financial evaluation is the main approach to evaluating process technology for most businesses. However, traditional measures, such as return-on-investment (ROI), can be difficult to calculate, especially if the costs and benefits associated with the technology are spread across the whole organisation. ROI models are much better adapted to narrowly defined, single product-market projects where the 'pay-back' benefits are clear. But, many technology investments are made for 'strategic' reasons, where the eventual returns might include improved reliability, productivity enhancements, increased speed of response, etc. Although these can be critical success factors in a service business, they are difficult to incorporate in an ROI model. Particularly when IT is involved, many managers don't really know the long-term value of their investment simply because they cannot predict if and when the technology will become obsolete. Also, many firms appear to take a reactive view of technology, and it is therefore unsurprising to discover that they have difficulties in assessing the real impact that such investments will have upon the competitive advantage of the firm. This is why the chapter takes a broader approach to technology evaluation using the ‘feasibility, acceptability, vulnerability’ framework. • Technology investment must be feasible – If the resources required to install a piece of technology are greater than those that are either available or can be obtained, it is infeasible. Three broad questions are worth asking: (a) What kind of skills, technical or human, are required? Every investment in process technology needs a set of specific skills to cope with the implementation. If an investment is similar to the usual activities of the organisation these skills will probably be present. But with a completely novel process, novel implementation skills might be needed. (b) What quantity of operational resources are necessary? This involves determining the number of resources – people, facilities, space, materials, etc. – that would be required to implement the process. (c) What are the funding or cash requirements? For many decisions the major feasibility issue concerns the cash that would be required. For some decisions this could mean simply examining a one-off cost, such as the purchase price. Other, more strategic process investments, may need an examination of its effects on the cash requirements of the whole organisation. • Technology investment must give acceptable benefits – By the ‘acceptability’, we mean the benefit it is expected to bring to an operation; unsurprisingly the greater the benefits, the greater the overall acceptability. A process technology’s acceptability is how far it fulfils the company’s objectives, in terms of the following. (a) Its operations resource capabilities. Process technology should provide resource capabilities that give a sustainable advantage by being, scarce, difficult to move, difficult to copy and/or difficult to substitute for. (b) Its market requirements. All process technology should contribute to the business in an operational context. So, use operations performance objectives to assess acceptability – giving more weight to those that contribute directly to competitiveness. (c) Its financial impact. The financial impact of process technology is the comparison of the costs to which the investment commits the operation, and the financial benefits that might accrue. Ideally, both the ‘costs’ of the investment and the resulting benefits ought to include everything that is influenced by the investment over its life. In fact, this is impossible in any absolute sense. The effects of any large process decision ripple out like waves in a pond, impinging on and influencing many other decisions. • Technology investment must not expose the operation to excessive vulnerability – The risk inherent in any process investment is there because one cannot totally predict three issues. (a) How it will affect the performance of the whole operation. (b) The external 310 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual conditions prevailing after the investment is made – for example, the volume of demand or the interest rate. (c) The reaction of outside companies to the investment – for example, whether competitors are likely to make similar investments. All these need assessing and putting in terms of the downside risk for the operation – the most pessimistic outcome possible. The key question then becomes, ‘Is the downside risk worth taking?’ Working with emergent technologies The ‘feasibility, acceptability, vulnerability’ framework approach to analysing process technology is both systematic and logical. However, under some circumstances the final set of criteria (vulnerability or risk) is so great that any use of new technology must be handled particularly carefully. This is especially true of emergent technologies whose efficacy have not yet been fully established. For example, in the music industry, Platinum Blue Music Intelligence uses a technology called Music X-Ray to analyse the underlying mathematical patterns in music. This process can be compared to the original x-ray when it was first introduced to medicine. The x-ray shows the doctor something that is already there but that could not be seen. The doctor then uses that information to make better decisions. Music X-Ray technology works in much the same way in that it shows music industry professionals their music and their market in ways they could not see it before. They say that their service… accurately predicts the success of hit songs and is thus used on the supply side of the music industry as a crystal ball. It helps the companies that make and sell music predict which songs are going to become hits due to the discovery that hit songs conform to a limited number of mathematical patterns that cannot be heard with the ear. Most singles released by music labels sound and feel like hits but lack these optimal mathematical patterns and this is a main reason why the industry has less than a 20% success rate. Less than one in 5 songs that are released as singles and promoted with a significant budget actually reach the charts. By using our technology hit rates can be increased to over 80%; four times the accuracy rate the industry currently has, effectively providing a risk management capability that helps yield massive improvements in return on investment. (Company web site) While this technology is undoubtedly valuable in the decision-making processes in the music industry, should it entirely replace human judgement? In other words, should the technology be seen as having sufficiently high acuity and judgement in terms of its analytical content (see earlier categorisations) to take over some of the decision making? It is already difficult to know exactly how this technology is being used. Even the music companies and record labels that use it are reluctant to talk about it (no one likes to think that their music is being generated from a box). Also, record companies are aware of the danger that all their products will eventually sound similar if it uses the same process technology to be selected. In fact, like many decision support technologies, the solution is to blend the information emerging from this technology with more conventional human judgement. This may not eliminate all the dangers of using this type of technology, but according to some industry analysts, ‘no record label can now ignore this type of screening’. 311 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Example – Technological races5 The ‘entrapment’ game – essentially, an auction ‘with a twist’. The auctioneer announces to the players that she is going to auction off a £20 note to the highest bidder. After someone opens the bidding, each following bid must exceed the previous one by at least 50p. The ‘sting in the tail’ is that once the bidding stops, not only the highest but also the second-highest bidder must give their bids to the auctioneer. The highest bidder gets the £20 note and the second highest gets nothing! Regardless of the type of player, the pattern of bidding remains very similar. Following the opening bid, offers quickly proceed to £10, or half the amount being auctioned. There is then a pause, as the players digest the fact that, with the next bid, the total of the two highest bids will exceed £20 and push the auctioneer into profit. Imagine yourself as the second-highest bidder at this point, considering what your options actually are. You can give up and take a certain loss of £9.50 or you can risk a little more and possibly win £9.50. At this point in the game, it is common for all but the top two bidders to drop out. If we return to our auction, as the bidding approaches £20, there is a second pause as the bidders appear to be pondering the fact that even the highest bidder is likely to lose money. Again, consider the alternative: dropping out means definitely losing £19.50. Once the £20 threshold has been crossed, the bidding quickens again, and from then on it is a battle of nerves. And if you are thinking to yourself that you would never be so silly as to get involved in a game that so strongly favoured cost escalation, reflect on the following. A psychology professor claims that over 10 years he won more than $17,000 auctioning $20 bills to his MBA students at the Kellogg Graduate School of Management. Players in the entrapment game ‘auction with a twist’ face similar drivers to those firms considering investments in new performance-enhancing technologies. If there are any kinds of ‘winner takes all’ factors at play (i.e. first-mover advantage) then investing just a little more than a rival can shift the results in one’s favour. At the same time, these factors also mean that very often the second-placed player faces minimal returns on his or her investment, if not actual losses and (of at least equal significance) the potential for appearing foolish. Investment to meet evolving customer needs The obvious driver of a firm’s motivation to invest in new process technology is that there has been some kind of change in customer needs. So, for example, in the food industry, regardless of whether requirements emerge for particular recipes (i.e. following media-led food fashions), alternative formats (i.e. more biscuits in a ‘family’ packet) or new packaging types (i.e. individually wrapped for snacking), each change requires manufacturers to modify their process technology. Some changes derive from specific requirements whereas others are part of longerterm trends. As a specific example, several new processing technologies, such as the in-packet pasteurisation of fresh pasta, have developed as the result of a general trend in customer preference for processed foods with high ‘perceived’ freshness (this is not necessarily the same as actual freshness). Other market changes can have a more profound impact. For instance, changes in consumer attitudes towards fat (especially saturated fat) have led many manufacturers, including global margarine producers like Procter and Gamble, to invest huge sums in developing and adopting technologies that could process reduced fat and reduced cholesterol-bearing products. 5 Adapted from Frank, R.H. and P.J. Cook (1995) The Winner Takes All Society, Penguin. 312 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The process life cycle Because scientific developments often occur independently of specific market dynamics, companies may be faced with a potential process technology in search of a sensible market application. Raytheon in the USA lost over $5 million with their first microwave oven by marketing it to industrial users and emphasising the technical performance of the underlying technology, rather than marketing it to catering operations and demonstrating the rapid cooking of popcorn. In the previous chapter we discussed some of the difficulties associated with separating product/service and process life cycles. Yet, the notion that a process technology has a specific life span is still a powerful one – especially when discussing whether to exploit a specific technological opportunity. This is where the ‘S-curve’ comes in. The so called ‘S-curve’ describes the relationship between research efforts (investment) put into improving a process technology over time and the performance outcome that is achieved as a result. The S-curve shape is as it is because of a number of factors. Initially, returns from any innovative process technology are low but as the technology is more widely adopted and its basic performance is improved, returns grow rapidly. Finally, as a technology matures, it becomes increasingly difficult to gain further technological progress no matter how much money is thrown at it. Several authors6 have used this curve to argue that as organisations reach the upper limits of a technology (point A in Figure 6.3), further investment is better spent on an entirely new S-curve that represents a new technology and a host of new opportunities (position B). Celebrated examples of a lack of awareness of the S-curve abound. For example, none of the top ten manufacturers of vacuum tubes (in the 1950s) was quick enough to see the impact of semiconductor technology and none of them was in this new top ten. However, the model should not be taken as offering simple prescriptions for operations strategy. But it is useful in forcing organisations to consider some critical questions: • How do we really know that a technology has reached its limit? • How can we be sure that customers will value investment in a new process technology? What about past investments and the underlying capability bases we have developed? • Will we be able to replicate the same level of capability? 6 Foster, R.N. (1986) Innovation: The Attacker’s Advantage, New York: Summit Books. 313 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The market and resource impact of process technology This uses a simple charting methodology applied to a police forensic laboratory to evaluate both market resource and operations capability dimensions. Here is a further example that demonstrates how this approach can be used. The original Payless operation opened in 1956 in Topeka, Kansas, with an extremely simple yet revolutionary service concept – instead of being guided by an employee towards their footwear purchase, customers browse independently in a self-service environment. This simple, yet appealing concept gave, and continues to give, their operations a basic efficiency that allows them to sell their shoes at low prices (today, most of their products sell for less than $15 a pair). In the 1990s Payless ShoeSource Inc. was spun off from its by then more diversified parent and became an independently traded company on the New York Stock Exchange (trading as PSS). Like most successful garment manufacturers, the business exploits a global network of factories and agents. Although somewhat late compared with other retail sectors and other competitors, the firm launched its new online retail business in 2000. The synergy with their established selfservice retail concept seemed to be strong. Adopting a relatively cautious approach to the new operation, PSS deployed an ‘off-the-shelf’ web front-end and order receipt system created by the Internet division of IBM. The ‘back office’ order processing was completed using the preexisting (and completely tried and tested) systems developed to support hundreds of individual retail outlets across North America. We will apply the market requirements and resource-based analyses described above. The complete analyses are also summarised in Figures 6.4 and 6.5. Quality – The online ordering system is essentially an extension, or new front-end, on the inventory and order management systems used to support the existing Payless stores. However, the simple-to-use web site (following the tradition of their self-service stores) does offer some 314 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual additional features such as a permanently available up-to-date catalogue and corporate information for the firm’s investors. The likelihood of ordering errors, though, could be greater if customers do not follow the site instructions. Speed – Although customers can now place orders from home, the physical distribution of shoes, etc. exploits the same back-office delivery systems as before. Therefore the overall speed of delivery can even be, if a customer has to wait for a courier to deliver their goods, actually slower than visiting a store with the product in stock. Dependability – As the underlying processes are the same, just as they are no faster, they are no more dependable in terms of product availability (although actual stock is more visible) and ontime delivery. Flexibility – The introduction of a complementary web-based service effectively extends the scale of their retail operations. The number of potential customers is no longer restricted to those within a reasonable travel distance from a store and likewise the ordering process is now available 24 hours a day, 365 days a year. Cost – Online transaction costs are a fraction of those associated with the traditional storeordering process that could involve considerable amounts of staff time. Unlike a start-up web retailer, Payless’s exploitation of established processes massively reduced their initial costs and, by increasing total volumes, reduced overall unit transaction costs. We can analyse the resource profile of the technology in a similar fashion. Interestingly, most of the hardware and software elements deployed by Payless were ‘off-the-shelf’ items: from the standard network servers to IBM’s Internet store solution. Figure 6.5 charts this resource profile and distinguishes between hardware, software and the intangible aspects of the technology. Scarce? – Although Payless created a fairly standard retail web site, more crucially, it enables the company to leverage their existing brand and thereby reinforce/protect it. 315 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Difficult to move? – It would be very difficult for another retailer to rapidly grow the same web presence independently of the already established retail brand and customer relationships (including sales data, customer preferences, etc.) that underpin it. Difficult to copy? – With the exception of specific logos and graphical elements, the basic functionality of any web ‘store front’ can easily be copied (especially one bought off the shelf from a global supplier). To a lesser extent this is also true of any back-office processes (recognising how far down the learning curve Payless are after decades of being in business). However the firm’s reputation – and the trust this creates – is inimitable. Difficult to create a substitute for? – Interestingly, on the S-curve, one could argue that the Internet is the twenty-first-century substitute retail technology. However, there is nothing that renders the technology itself intrinsically difficult to substitutes. Most crucially for Payless, a web presence extends their market position (more than 4,000 stores), allowing them to exploit and defend their already significant incumbent’s advantage. A final word on process technology evaluation It is worth remembering that, in practice, the choice of new technologies is far less rational and ‘clinical’ than the impression given in Chapter 6. Usually, investment decisions of this type are made against a background of opposing factions in the managerial team with different views of how the market may change, what risks are appropriate, which technologies represent the way of the future and which represent technological ‘dead-ends’ and so on. The issues and questions outline in Chapter 6 should therefore be considered as providing a set of checklists and structures that can raise this debate to a higher level rather than give any answers as such. 316 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 7 Improvement strategy Chapter aims There is an important distinction between how organisations set up their strategy for on-going improvement and how they review their overall operations strategy, which is done relatively infrequently. The latter issue is known as the operations strategy formulation process and is covered in Chapters 9–10. The aims of this chapter are to: • Define the basic idea of an improvement strategy. • Explore different approaches to improvement, especially the balance between ‘top-down’ management-driven improvement and ‘bottom-up’ shop-floor improvement. • Examine the nature of performance measurement. • Describe the importance–performance approach to prioritising for improvement. • Discuss the model of operations improvement which contains the three concepts of ‘fit’, ‘learning’ and ‘contribution’ (or Direct, Develop, Deploy). • Understand the ‘four-stage’ model of operations contribution. Improvement in operations strategy Only a few years ago there was relatively little effort devoted to how operations could improve, with more emphasis being placed on the routine decisions that simply ‘kept the show on the road’. But now there is a large body of opinion that recognises the importance of operations staying ‘ahead of the game’. For example: ‘The companies that are able to turn their…organizations into sources of competitive advantage are those that can harness various improvement programs…in the service of a broader [operations] strategy that emphasizes the selection and growth of unique operating [competences].’ Hayes and Pisano 1996, p.40 Partly because of this, operations managers have seen a huge range of essentially faddish solutions to a range of perceived problems, with the over-implementation of techniques that were viewed as panaceas (and were therefore almost by definition ‘doomed to disappoint’). Yet nearly all the techniques had some potential value, but too often organisations lacked a sufficiently strategic view of what was necessary to make operational improvement possible. 317 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Breakthrough improvement or continuous improvement? The chapter, like most treatments of this subject, divides improvement ‘philosophies’ into ‘breakthrough’ or ‘major’ improvement projects, and more ‘continuous’ or incremental improvement. But this is something of an artificial distinction. Most organisations will require a mix of both types of improvement as well as some improvements that are somewhere in between these two types. To some extent, the relative emphasis placed on either continuous improvement or breakthrough improvement will depend on the degree of process change that is implied by the improvement. The chapter distinguishes between four levels of process change from ‘modification’ through to ‘extension’ through to ‘development’ through to ‘pioneer’. Figure 7.1 makes the connection between the type of improvement approach that will be necessary and the degree of process change. Although there is no simple distinction between breakthrough and continuous improvement, generally the greater the change the more likely it is that breakthrough approaches to improvement will be appropriate. Benchmarking Benchmarking highlights how key operational elements compare against ‘best in class’ competitors, so that key areas for focused improvement can be identified. However, benchmarking does not provide a vision of how to go beyond competitors. As Prahalad and Hamel (1994) say: 'Path breaking is a lot more rewarding than benchmarking. One does not get to the future first by letting someone else blaze the trail.' Yet benchmarking may not always imply the simple ‘copying’ of some other organisation’s ideas. If one takes a far broader view of benchmarking, it could include the general comparison of one’s own approach to managing operations with some other organisation’s approach. In this case benchmarking is not being used in order to simply compare performance levels, nor is it being used to seek out ‘best practice’ as such. Rather, one is looking at other organisations for challenges, alternative views or simply inspiration. And whilst not advocating ‘industrial tourism’ as it is sometimes called, for its own sake, examining other organisations’ approaches to operations strategy can often be helpful if only to contextualise one’s own approach. The ‘Direct, Develop, Deploy’ model It is useful to have some strategic conceptualisation of what is necessary to encourage operational improvement. This is where the ‘Direct, Develop, Deploy’ model is useful, it uses the powerful idea of the improvement cycle to identify three different, but clearly related, mechanisms, without which no improvement strategy could be complete. 318 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Direct – means ensuring that there is fit between market and operations resources. • Develop – means that the capabilities of these operations resources are improved through learning over time. • Deploy – means that these operations capabilities are contributed to shaping market position. Figure 7.2 illustrates this idea. Getting the fit right – Direct An important, and usually the first, stage in any improvement strategy is to make sure that improvement is very clearly linked to the requirements of the organisation’s markets. This means first of all understanding markets and then translating market requirements into a set of performance measures that both reflect market requirements and have meaning within the operation. Performance measurement Strategically, an important question is, 'How do we know if our operations are good, bad or indifferent?' In other words, how do we begin to judge the performance of the resources and 319 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual processes which; taken together, comprise investment in the operation? Unless performance is regularly assessed in some way, there is no basis for evaluating operations effectiveness. And unless we have some idea of exactly how effective our operations are, we have no sound basis for devising means of improving our operations. Traditionally, performance measurement has been seen as a means of quantifying the efficiency and effectiveness of action. Performance measurement concerns ‘sensing’ performance and evaluating it by ‘comparison’ against ‘standards’. This view gives rise to what the chapter terms the four generic issues of performance measurement. These are, • What factors to include as performance targets? • Which are the most important? • How to measure them? • On what basis to compare actual against target performance? What factors describe performance? The history of operations performance measurement has been one marked by the steady broadening of the scope of what it is regarded as appropriate to measure. If the operations function is responsible for more than cost and productivity, it should measure more than cost and productivity. It was then an issue of broadening out the natural scope of measurement to encompass external and internal, long-term and short-term and ‘soft’ and ‘hard’ measures. The ‘Balanced Scorecard’ approach taken by Kaplan and Norton, argues that adopting a balanced range of measures enables managers to address the following questions1 • How do we look to our shareholders (financial perspective)? • What must we excel at (internal business perspective)? • How do our customers see us (the customer perspective)? • How can we continue to improve and create value (innovation and learning perspective)? It was dissatisfaction with traditional performance and control systems, often designed and managed by accounting specialists, which led to the development of the Balanced Scorecard Approach. It had long been recognised that inadequately designed performance measures could result in dysfunctional behaviour. And as well as focusing almost exclusively on financial measures of performance, traditional performance measurement systems did not provide the important information that is required to allow the overall strategy of an organisation to be reflected adequately in specific performance measures. Although the balanced scorecard approach does include financial measures of performance, it also includes more operational measures of customer satisfaction, internal processes innovation and other improvement activities. In doing so, it measures the factors behind financial performance, which are seen as the key drivers of future financial success. 1 See Kaplan, R.S. and D.P. Norton (1996) The Balanced Scorecard, Harvard Business School Press, Boston, MA. 320 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Developing a balanced scorecard is a complex process and is now the subject of considerable debate. But the approach does attempt to bring together many disparate elements which reflect an organisation’s strategic position. These may include product or service quality measures, product and service development times, customer complaints, labour productivity and so on. At the same time, it attempts to avoid performance reporting from becoming unwieldy by restricting the number of measures and focusing especially on those seen to be essential. The advantages of the approach are that it presents an overall picture of the organisation’s performance in a single report and by being comprehensive in the measures of performance it uses, encouraging companies to take decisions in the interests of the whole organisation rather than sub-optimising around narrow measures. One of the key questions that has to be considered during this process is how specific measures of performance should be designed? It is recognised that inadequately designed performance measures can result in dysfunctional behaviour, so teams of managers are often used to develop a scorecard that reflects their organisation’s specific needs. Perhaps one reason for the popularity of the balanced scorecard approach to performance measurement is that the four categories of performance measures used are very similar to the four perspectives of operations strategy (see Chapter 1). Figure 7.3 illustrates how Kaplan and Norton’s category of financial performance measures is very close to what we have called earlier the top-down perspective of operations strategy. Their idea of ‘customer performance measures’ is equivalent to what we have called the market requirements perspective of operations strategy, their ‘internal process performance measures’ is the same as what we have called the operations resource capability perspective on operations strategy and their ‘learning and growth performance measures’ corresponds to what we have called the bottom-up or emergent perspective on operations strategy. 321 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Which are the most important performance measures? The chapter frames this question as trying to achieve some balance between having a few key measures on one hand (straightforward, simple, but may not reflect the full range of organisational objectives), or, on the other hand, having many detailed measures (complex, difficult to manage, but capable of conveying many nuances of performance). The compromise is to make sure that there is an explicit link between competitive strategy, the performance objectives that are given to the operations function, the key performance indicators (KPIs) that reflect the main performance objectives and the bundle of detailed measures that are used to ‘flesh out’ each key performance indicator. However, unless competitive strategy is well defined (not only in terms of what the organisation intends to do but also in terms of what the organisation will not attempt to do), then it is difficult to focus on a narrow range of key performance indicators. How do we measure them? The key question here is, ‘What is an ideal performance measure?’ The following is a useful set of criteria against which we can judge individual performance measures2. • Performance measures should be derived from strategy. • Performance measures should be simple to understand. • Performance measures should provide timely and accurate feedback. • Performance measures should be based on quantities that can be influenced, or controlled, by the user alone or in co-operation with others. • Performance measures should reflect the ‘business process’ – that is, both the supplier and customer should be involved in the definition of the measure. • Performance measures should relate to specific goals (targets). • Performance measures should be relevant. • Performance measures should be part of a closed management loop. • Performance measures should be clearly defined. • Performance measures should have visual impact. • Performance measures should focus on improvement. • Performance measures should be consistent (in that they maintain their significance as time goes by). • Performance measures should provide fast feedback. 2 Neely, A.D. (1998) Measuring Business Performance, Economist Books, London. 322 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Performance measures should have an explicit purpose. • Performance measures should be based on an explicitly defined formula and source of data. • Performance measures should employ ratios rather than absolute numbers. • Performance measures should use data that are automatically collected as part of a process whenever possible. • Performance measures should be reported in a simple consistent format. • Performance measures should be based on trends rather than snapshots. • Performance measures should provide information. • Performance measures should be precise – be exact about what is being measured. • Performance measures should be objective – not based on opinion. What basis to use to compare actual against target performance? The discussion in the chapter under this heading is an interesting and important one. Namely that the way we view a performance measure will depend entirely on the ‘standard’ we compare it with. This ‘standard’ reflects the threshold between what is considered acceptable performance and not acceptable performance. It uses an example of delivery performance and compares it against four different ‘standards’ to show how our judgement of whether performance is acceptable varied depending on the standard. • Historically performance is good (or at least better than it was). • Against the company’s improvement goal, it is poor (83% against 95%). • Compared with competitors it is good (they only achieve 75%). • Against what it could be potentially it is poor (an absolute level of 100% – perfection). So how we judge a performance measure very much depends on the standard against which we compare it. Different standards will be appropriate in different circumstances. • Historical standards – are useful for some improvement programmes where the rate of improvement is a key issue, or where it is important to celebrate progress. • Target-based standards – are useful where, like all budgets, one needs a figure around which to plan other activities, or where the target is seen as exercising constructive motivational impetus to an improvement programme. • Competitor-based standards – are particularly useful in longer term strategic decision making. After all, as the organisation improves, it is that piece of improvement that takes it past its competitors who may have the most utility. An equivalent to competitor-based standards for non-competitive operations would be to use the performance levels achieved by similar operations elsewhere. 323 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Absolute performance standards – are useful for calibration purposes. In effect, they highlight the amount of improvement that has still to be made. Improving from 60 per cent delivery performance to 83 per cent is not so much an improvement of 23 percentage points; rather it is slightly over halfway to the ultimate goal. Prioritising improvement – the importance–performance matrix In most companies, finding things to do which will make them better is not a difficult task. Deciding which of these many improvements to tackle first is far more difficult. However there are some basic rules that can be used to guide prioritisation. For example, ‘do the easy things first’ (the ‘low-hanging fruit’ approach), ‘do the cheapest things first’, ‘do the things that our customers are complaining about first’, ‘do the things where we believe ourselves to be vulnerable to competitors first’ and so on. The approach we discuss in this lesson has been found to be a useful procedure in practice, and furthermore takes a relatively strategic view of the improvement process. By this we mean it links an external view of the way products and services are viewed in the marketplace to an internal view of how good we are at delivering (in the broadest sense of the word) these products and services. The idea of the importance–performance gap driving improvement is not new. The chapter’s version of it uses 9-point scales. It uses the running example of TAG Transport to demonstrate the use of this approach. Essentially the whole idea of the importance–performance matrix is to help operations to prioritise the particular competitive factors or performance objectives on which they should be concentrating. Let us summarise their description of this technique as a step-by-step procedure. • Step 1 – Select one product or service into one market – In fact the chapter does not emphasise this issue but it uses the technique initially to look at one particular service into one market. This is quite important as we shall discover later. Performing this technique on whole operations, which may be producing a wide range of products or services and selling into several different markets, only results in generalities on the matrix that are of little value. To begin with, it is best to get used to how this approach works by selecting a relatively clearly defined product or service and consider it from the point of view of satisfying one of its markets. Choosing a product or service that is either accepted as being clearly very good or obviously very bad would probably not be wise! To begin with, it has been found useful to select a product or service where there can be genuine debate over the way it is produced. • Step 2 – Identify relevant competitive factors – This step involves selecting a range of performance objectives that have some relevance to the customers for the product or service. Remember here to distinguish between the customers who are the immediate purchasers of the product or service and the end consumers. Choose one or the other to base your analysis on, but do not mix the two. Most organisations prefer initially to work from the customers’ point of view rather than the ultimate consumers. The next issue is to select the appropriate factors. A useful way of doing this is to start from the five performance objectives (quality, speed, dependability, flexibility and cost). Almost certainly however, these will need to be customised to make them appropriate for the chosen product or service. So, in the example used by the chapter, the simple performance objective ‘quality’ is divided into ‘service quality’ and ‘distribution quality’. It is best to use the five performance objectives as a starting point or checklist and then develop appropriate factors from them. 324 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Step 3 – Rate the factors on the 1 to 9 importance scale – This is a relatively straightforward procedure – just pick the relevant point that seems closest to how you see the importance of each factor to customers. Of course, it may be that you cannot fit one of these statements exactly to your understanding of customers’ views. Remember this is not a precise exercise. Remember also that it is quite intentionally subjective. The technique is asking individual managers or a group of managers to articulate their understanding of how customers value aspects of their performance. If, on reflection, the views of the customer group chosen are too disparate to be summarised in a single point, then identify a range. • Step 4 – Identify operations performance on the 1 to 9 scale – Again remember that this is not a formal benchmarking exercise; it is a subjective assessment of how the operation sees its performance relative to its competitors. It is worth mentioning though that, of course, this might prove difficult in many organisations. Unless some effort has been put into monitoring competitors’ operations performance, it may be difficult to make this judgement. If so, (a) it is a salutary lesson for any organisation to admit that they do not know such basic competitive information, and (b) managers will just have to make an impressionistic judgement. The other point to note at this stage is that the chapter uses ‘cost’ instead of ‘price’. This is because comparing a company’s prices against their competitors may not be too revealing. Either prices are set deliberately to differentiate the company from its competitors or, alternatively, market forces may have pushed prices together anyway. Far more revealing from an operations point of view is a comparison on a cost-bycost basis. That is, ‘are our costs of producing this product or service better, the same as, or worse than, our competitor?’ • Step 5 – Plot the points on the importance–performance matrix – The matrix itself is shown in Figure 7.7 of the chapter. It is divided into four zones. These are: (i) the high priority zone or urgent action zone;(ii) the improve zone (containing elements of performance which need to be improved but not as a priority if there are other elements within the urgent action zone); (iii) the appropriate zone where performance is judged to be reasonable; (iv) the excess? (note – the question mark is important) zone where the performance factors need to be questioned to check whether excess resources are being used to maintain these levels of performance. If any factor appears in this zone, it does not necessarily mean that it has to have resources taken away form it – merely that questions should be asked. Drawing the matrix with these clear distinctions between zones is somewhat misleading. Obviously, the bottom right-hand side of the matrix does imply urgent action and the top lefthand side of the matrix does imply some kind of excess; however, do not take the lines between the zones as being definitive. In reality, perhaps one should regard them as where one zone gradually merges into another. The idea behind the matrix is to give a broad indication of how one might approach the degree of prioritisation to put behind improvement in each area. Also, consider what the matrix is really doing. It is encouraging operations managers to consider similar aspects of their performance from two quite different perspectives. • The external perspective – how customers and markets would view these aspects of performance. • The internal perspective – how good the operation is at performing on each aspect of performance. 325 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual In this way, it is attempting to bring market and operations perspectives together. In effect, it is an approach that could be said to help the principle of strategic fit (see Lesson 8). It is doing so by identifying ‘gaps’ between what is (customer perspective) and what should be (operations performance). More to the point, it forces management teams to articulate their underlying assumptions about what drives improvement prioritisation. Experience of using this technique has shown that managers often have surprisingly varied perceptions of both importance and performance. Yet when asked if they believe that their perspective would be shared by their colleagues, they nearly always believe it would. Joint discussions as to exactly how importance and performance of each factor should be rated help to ‘get things out on the table’. Where differences still persist, they do become clearer. In fact, rarely does the matrix show any particular surprises. But it does help to discriminate between different degrees of urgency or prioritisation to be allocated to each factor of performance. This is why the technique is intended to be used as a formalisation of subjective perceptions. The whole idea is to expose consensus, or the lack of consensus. Moving prematurely into sophisticated customer surveys or benchmarking exercises is something that might make sense later on, but not at this stage of prioritisation. Sometimes managers merely hide behind formal survey results rather than face up the issues of their own strategic ignorance. In fact, the exercise itself can give some important guidelines to where further research, of a more formal nature is necessary. Building capabilities through learning – Develop This step is arguably the most important stage in developing an improvement strategy. Put simply, ‘how can one ensure that the basic resources and processes acquired by the organisation are used in such a way as to build operations capabilities?’ Different organisations in the same industry may have identical process technologies, use very similar process configurations and adopt common organisation structures. Does this mean that the performance of these organisations will inevitably be the same? Of course it does not. In fact, almost certainly their performance will be different. So, what explains these differences? It is their ability to learn how to use the resources that they have acquired. It is the sometimes subtle and tacit knowledge that is built up and (hopefully) captured through the experience of using the resources. And this is what the ‘develop’ stage of the model is about – how an organisation can build unique capabilities through learning. The learning/experience curve The chapter explain the learning/experience curve in terms of how the relationship between the time taken to perform a task and the accumulated learning or experience was first formulated in the aircraft production industry in the 1930s. Studying production data revealed that the reduction in unit labour hours was proportional to the cumulative number of units produced. Every time the cumulative output double, the hours reduce by a fixed percentage. Similar examples were found elsewhere, for example, in labour-intensive manufacturing, such as clothing manufacture. A reduction in hours per unit of 20 per cent was found every time cumulative production doubled. This is called an 80 per cent learning curve. The text explains that when plotted on log–log paper, such a curve will appear as a straight line – making extrapolations (and strategic planning) more straightforward. 326 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example - Dell (part 1) learning how to turn difficulties into advantages The purpose of this example is to demonstrate that capabilities can be developed notwithstanding what may seem like unpromising circumstances. Dell were forced into adopting a different supply network configuration (bypassing conventional retailer channels) as the only way that they could compete with the low prices being offered by their more established rivals. However, rather than simply see this strategy as ‘the only feasible option’, they actively explored whether it would be possible to gain benefits from having no retail outlets. The lesson here is that there are often potential positives and negatives to every strategic option. Just because one is forced into an unorthodox competitive stance does not necessarily mean that the potential negatives of a strategy outweigh the more obvious positives. By being both energetic and creative, Dell managed to turn the disadvantages of having no retail outlets into a set of advantages built upon having direct contact with their consumers. Learning and knowledge An essential element in improving operations is to establish what is going on in your own operation. You can never go on to be creative in the management of operations unless you have a relatively full knowledge of your processes. The question is how do we measure our degree of knowledge about how to produce goods and services? The text describes the approach to this, which has been put forward by Roger Bohn. He described an eight-stage scale ranging from ‘total ignorance’ to ‘complete knowledge’ of the process. Table 7.4 in the chapter summarises some aspects of these eight stages of knowledge. Remember though that not all processes will ever get to the higher states of knowledge. Often changes to technology or market requirements ‘knock back’ the learning to a lower state of knowledge and the operation has to carry on developing its process knowledge to this lower base. Obviously, when variety is high and the environment turbulent, it becomes difficult to progress beyond a relatively low state of knowledge. However, strategies such as modular design (i.e. used extensively in software production) allow a greater degree of standardisation, which in turn allows a greater degree of stability. This allows the process to be controlled at a higher level of knowledge. Using the Bohn scale of process knowledge Step 1 Select a process. Maybe one for which you are responsible, or one with which you are familiar, or one which is important to the success of your organisation, or alternatively, choose a domestic process with which you are familiar, for example baking biscuits (cookies). Step 2 Consider what your ‘state of knowledge’ of the process is, according to the Bohn scale. • Stage 1 – You can recognise what the process is doing but have no idea how it does that. 327 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Stage 2 – You have a broad understanding of what affects the performance of the process but could not say, which are the most important factors affecting performance. • Stage 3 – You understand, in detail, what is supposed to happen in the process and have written process procedures that have been designed to try and get the most out of the process. • Stage 4 – You have detailed and documented process procedures that are understood by everyone in the process. You also know how to change the design and operational practice of the operation so as to change its average performance. • Stage 5 – You know what factors cause variation in the performance of the process and can control or eliminate these factors to make the performance of the process predictable. • Stage 6 – You know exactly how the process would perform under different circumstances such as performing a different task or working with a new IT system. • Stage 7 – You have a clear, mathematically formulated, understanding of why all the cause– effect relationships within the process work as they do and can quantify them in such a way as to optimise performance under any set of circumstances. • Stage 8 – You know everything about what happens in the process, how it happens and why it happens. You probably also know how the process fits into the greater meaning of life, the universe and everything. Leave the course now – you do not need it! Here is how different stages of a cookie baking process might be viewed (adapted from Bohn’s original paper). Stage 1: Complete ignorance Stage 2: Awareness Stage 3: Measurement Stage 4: Control of mean Stage 5: Capability Do not even know what influences results. Any variation considered ‘random’. Mix anything in cupboard together, bake for ‘a short time’. Observe others in kitchen. Begin to build list of possibly relevant variables, for example ingredients, time of day, baking time, weather. Have a vaguely defined mixing procedure. Learn to measure key variables. But no precise details of mixing procedure. Develop countdown schedule and sequence of mixing actions and times. Only bake on days when weather seems suitable. Decide not to bother about time of day since it does not seem to make a difference. You practice measuring ingredients until 95% reliable. Write down recipe as a ‘formal document’. Cookies now taste OL but appearance may sometimes vary and some are very occasionally burnt. 328 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Stage 6: Characterisation Stage 7: Know why Getting to Stage 8: Complete knowledge You run a series of experiments on many variables including baking time and temperature, exact quantities and so on. Discover effects of small variations in quantities. If you are asked for a different type of cookie, you can make it without having to go back to basics. Discover that weather has no significant effect on results. You go to local university. Study the science behind baking. You derive formulae that predict sweetness, texture and so on. If you want to back a batch quicker you know how to adjust temperature, ingredients and so on. You understand the effect of variables as yet unconsidered (and which may not ever change) such as size of cookie, type of baking tray. You can predict the effect of any change in the process that is suggested without any experimentation or trials. Contributing to Operations Capabilities – Deploy No matter how excellent an operation’s capabilities, they are wasted if they are not fully leveraged into the market place. Many of the issues concerning operation’s contribution to strategy have been covered already in this course. The text puts forward a particularly powerful model to illuminate this stage of strategic improvement. It is the Hayes and Wheelwright’s 1 to 4 model. This, in effect, attempts to calibrate the degree of operations contribution. Their ‘Stage 4’ operations had not only enhanced their own process capabilities but were quite clearly also the drivers of the organisation’s strategy. Commentary on example – Siemens leverages its global capabilities This example demonstrates how different types of operations in different locations, even when they are part of the same business, can deliberately develop different capabilities. Furthermore, the driver for how capabilities are built in any operation must take account of its location. So, for example, the company’s locations in China have a set of responsibilities that include developing low-cost component and product manufacture as well as developing an understanding of how product development processes can take account of the needs of the Chinese market. More expensive European locations need to develop broad technical capabilities, more advanced and/or sophisticated manufacturing capabilities as well as the flexibility to change what is being made or overall production volumes. Now it may seem obvious that different parts of a large group such as Siemens will need to develop different capabilities at different sites. However, some organisations attempt to impose common ‘one size fits all’ approaches to improvement and development throughout their whole organisation. This can inhibit the development of capabilities that are customised to the role of the site within the total group. 329 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Hayes and Wheelwright’s 4-stage model The chapter describes a model, originally devised by Hayes and Wheelwright. It is a four-stage model that articulates a progression from: • Holding back the business (Stage 1), to • Achieving similar performance to the rest of the industry (Stage 2), to • Being clearly the best in the industry (Stage 3), to • Using the capabilities of the operation to achieve longer-term superiority. (Stage 4) 330 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 8 Product and service development and organisation Chapter aims • To establish why the way in which companies develop their products and services is so important • To examine the process used by some companies to develop products and services • To take a market requirements and operations resource view of new products and service developments • To introduce the idea of the funnel of development as a method of articulating the management of the development process • To highlight the times in the development process where management attention is particularly important • To look at some issues on the management of development teams Introduction Competition on an increasingly worldwide basis and novel technologies means that product and service development is both important and challenging. Organisations are continually renewing themselves through the way they use their resources and capabilities to develop new products and services. Why is product and service development strategically important? How organisations develop their products and services is strategically important for two reasons. The first is that organisations who manage the development process so attractive products and services with appropriate market characteristics, quickly, dependably and efficiently, will maintain its revenue streams over time. The second and in some ways more important reason is that it reflects the underlying characteristics and capabilities of the organisation. Those businesses that have developed unique internal capabilities have created for themselves the option of leveraging those capabilities in the design of their products and services. Those that are creative in the way they manage their day-to-day operations are likely to be creative in the way they develop their products and services. 331 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Example – Introducing the ballpoint pen1 The chapter discusses the development of new products and services in the context of both product and service change and process change and makes the point that requiring an organisation to make significant degrees of change in both its products or services and the processes that create them can be far more difficult than simply changing the product or service on one hand or the process on the other. In Chapter 8, their Figure 8.3 illustrates this idea by demonstrating how introducing new branch banking services in a retail bank was less difficult than when the banks introduced their internet banking services. Here is another example. In 1938, two Hungarian brothers, Ladislao and Georg Biro, patented a design for a revolutionary ballpoint pen. By 1944 the brothers had managed to develop a manufacturing process and started to produce their first commercial products. Distribution rights for the US market were bought by a fountain pen manufacturer called Eversharp. However, a Chicago businessman, Milton Reynolds, had seen the biro pen while travelling in Europe, had liked what he saw and had a copy product on sale in a New York department store before Eversharp received their first delivery. Not surprisingly, Eversharp sued in the courts and in the legal wrangling which followed it emerged that in fact there had been an earlier patent for a ballwriting pen as far back as 1888. Meanwhile, both Eversharp and Reynolds enjoyed some success with their ballpoint pens, Reynolds developing the first product enhancement when they introduced a retractable point which clicked in and out of the pen barrel. However, although the design was revolutionary, it was far from perfect. The pens were prone to blotting and leaking and sales dropped severely as the public lost patience with such unreliable products. Eventually, both Eversharp and Reynolds were forced out of business because of the problems. Another established pen company, Parker, then stepped into the market but with a product redesigned to overcome its reliability problems. In fact, Parker enjoyed many years of commercial success with their improved product. This success encouraged other companies to enter the market, perhaps the most innovative being Bic, a French manufacturing company. Bic’s success lay in developing the manufacturing process to a level that enabled them to produce pens which could sell at around a tenth of their competitor products. This revolutionised the market. The ballpoint’s competitor, the fountain pen, became a low-volume niche product and the ballpoint became a consumer disposable. Figure 8.1 illustrates the changes that each of these organisations made in order to produce their pens. The original Biro brothers developed an idea that was new (at least they thought so) which was, in the context of this example, developed through advanced research and development. Eversharp essentially took the Biro brothers’ original design (relatively low product change) but had to develop a very new process in order to make it. When Reynolds copied Eversharp’s design it made even less change to the product itself although, like Eversharp, it had to develop very new processes to make the product independently of Eversharp. When it entered the same market, Parker redesigned the product to overcome reliability problems but only made relatively small changes to the process that both Reynolds and Eversharp had adopted. The eventual success of Bic derived partly from their changing the product to make it more manufacturable, but mainly from their development of an extremely effective high volume manufacturing process. 1 Schnaars, SP (1994) Managing Imitation Strategies, The Free Press, New York. 332 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – Spangler, Hoover and Dyson In many English-speaking countries people talk of ‘Hoovering’ their carpets rather than cleaning them. This is an indication of how the Hoover Corporation dominated the vacuum cleaner market for many decades. But in terms of product development it is the beginning of Hoover’s story and their history over the last few years that are the most interesting. As the example describes, it was not Hoover who invented the vacuum cleaner it was Spangler. No one speaks of ‘Spanglering’ their carpets. That was because (a) Spangler perhaps did not fully understand the importance of his invention, and (b) it is the organisations that do understand powerful product innovation when they see it and are capable of commercialising the idea who appropriate both the value and the fame. Yet nothing lasts forever. The example also describes how a new approach to the same product function developed by James Dyson has overtaken Hoover in terms of sales and profitability. It is also worth noting why Dyson succeeded in knocking Hoover off the top spot. First, he was creative in the way he developed ideas. Second, he was exceptionally persistent in the way he worked at that idea until it came right. Third, he understood the power of design. If a product looks good and works well the market will pay a premium for it. Who knows whether we will be Dysoning our carpets in the future? Product and service development and the four perspectives on operations strategy A useful perspective from which to describe the strategic development of new products and services is to return to the four perspectives on operations strategy as outlined in Chapter 1. Figure 8.2 uses these four perspectives to construct a 2X2 classification of the four organisational roles that are particularly important in the development process. In this case, we 333 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual combine both the operations role and any ‘technical’ role that may be involved in product and service development under one heading – operations resource capabilities. This simple classification allows one to ask eight basic questions regarding how product and service development is organised. • How effective is the strategic market function at understanding market opportunities? • How effective is the strategic operations function in development long-term capabilities? • How effective is the day-to-day marketing (and/or sales) function in understanding what customers really value in practice? • How effective is the day-to-day operations function in learning from their experience in order to build long-term capabilities? • How effective is strategic communication between the marketing and operations functions? • How effective is the operational level communication between the operations and marketing functions? • How effective is the top-down and bottom-up communication in the marketing function? • How effective is the top-down and bottom-up communication in the operations function? Let us illustrate these organisational routes and the role of the four functions with a hypothetical example. A company producing bottled water was aware that an increasing proportion of sales were coming through vending machine outlets. The company’s product was particularly gaseous (fizzy and had traditionally used glass bottles in order to ensure that the product did not lose its fizzyness before it was sold. The company’s sales representatives had become aware that there were a rising number of comments from customers about the problems of transporting and loading glass bottles into vending machines. Not all vending machines were suitable for such 334 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual heavy products. The following stages shown in Figure 8.3 describe each part of the ‘route’ taken by this product development. • This trend was reported upwards to senior marketing executives who conducted a survey to assess the market growth of vending machine sales and the market attractiveness of a plastic bottle. • On finding that this would be an attractive product they asked strategic operations and technical management to explore the challenges involved in moving from a glass to a plastic bottle. The strategic operations team knew that it would be very difficult to develop a suitable bottle and closure (screw cap) that could guarantee product integrity (i.e. the water would retain its fizzyness). • They requested their research and development laboratories and their process engineers to jointly explore the new skills and capabilities that would be needed to produce a plastic bottle that would retain product integrity. • Whilst developing various possible solutions, the laboratories and process engineers communicated regularly with the sales representatives in order to find out in detail the requirements of the new plastic bottle and to explore the acceptability of the various ideas that they were developing. • Although it took many months to develop suitable technologies and production methods to produce such a bottle, they eventually believed that they had found a suitable solution. It would involve both significant capital investment and a degree of risk because of the novelty of the technology. These findings were discussed with senior operations management in order to check whether the investment and associated risks would be feasible. • Once a clear idea of how the new investment would fit within the overall development of technical capabilities with the organisation, the strategic operations team developed recommendations that were communicated to the strategic marketing team. They jointly then took the proposals to the company’s board for a final decision. Although the above example is obviously highly simplified (and unusually successful in terms of the ability of the various parts of the organisation and their communication skills), it does provide an illustration of how development can happen. Of course, even in other successful development the ‘development route map’ may not be the same as this one. Ideas for new product and service developments can come from any of the four functional areas specified in the diagram or even from more than one simultaneously. 335 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Managing the internal design chain’s resources The chapter describes a typical process, stage by stage, which organisations go through to design product and services. However, as is mentioned, the idea that products and service development follows a set pattern of stages does not happen in quite such an orderly way in practice. It is useful to re-examine some of the points made by the chapter in terms of what does happen, rather than what should happen. In particular • Is the process of filtering out alternative product and service designs quite so orderly and rational as it seems from the textbook treatment of the subject? • Where should management effort go during the development process? • Is service design and development really the same as product design and development? • Most organisations have several development projects happening simultaneously. What issues arise from managing many projects at once? The funnel of development in reality The idea of the funnel of development is straightforward. The mouth of the funnel needs to wide enough to capture enough knowledge and ideas to stimulate embryonic product and service developments. This may be done through systematic searching of research publications, examination of competitors’ activities, and rigorous and systematic focus group activity with customers, regular meetings with suppliers and so on. The task then is to put organisational mechanisms in place which progressively narrows the funnel down such that ideas which are not capable of being developed further are dropped and do not take up more of the organisation’s time and effort. Most authorities suggest this is done through a filtering procedure (the use of screening criteria) which fits the company’s technological resources and competitive objectives. 336 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Planning and management attention The whole concept of the development funnel is really an articulation of how a company believes it ought to be making decisions about the development process. A closely related idea is that management should also schedule the extent of their involvement with development projects in advance. One would assume that wherever the funnel is changing its dimensions (i.e. the number of potential ideas is increasing or they are being discarded) senior management will need to be involved in these decisions. But, just as in reality, development funnels are not smooth, pre-planned and rational, so management attention is not always planned to be available when it can have the most effect. Figure 8.4 illustrates how one authority observed the degree of attention given by management to one particular development project and compares it with an assessment of management’s ability to influence the final outcome of the development. Clearly, management’s ability to influence any development project is highest in the earlier stages of development. As decisions are made, the ‘room for manoeuvre’ to change the details of the project rapidly diminishes. In the example in Figure 8.4, this reduction in the ability to influence things is particularly rapid when detailed design decisions are being made during the ‘basic design’ phase. The contrast with the degree of attention given to the project by senior management could hardly be starker. During the phases of ‘knowledge acquisition’ and ‘concept investigation’, and indeed during ‘basic design’, management attention was minimal. Presumably it was assumed that these stages were relatively routine. During the ‘prototype build’ phase the company started to experience problems in converting the design from paper to reality. This caused some friction between departments. Senior management were called in to mediate between the departments, as well as provided the extra resources necessary to solve any problems. As ‘pilot production’ started the problems began to be ironed out and senior management attention once more diminished. However, during ‘manufacturing ramp-up’ a whole new set of problems to do with the company’s ability to manufacture the design cropped up. Again this required senior management attention and mediation. Finally, after these manufacturing issues had been sorted 337 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual out, and management’s attention again subsided and the launch of the product into the market brought another batch of problems. The point being made here (and one made by many authorities in this field) is that management attention should not be reactive, as implied by Figure 8.4, but rather planned proactively to be involved in decision making ‘before the fact’ rather than ‘after the fact’. Example – Then Netscape changed2 It is worthwhile noting that, in addition to the factors discussed in the chapter, organisational issues can play a hugely important role in determining the success of product and service development projects. The following example provides an illustration of how cultural issues can change within organisations and affect both its culture and its ability to innovate. It was an archetypal, loosely organised collection of free spirits. They were the kind of development group that was always associated with software developers working on the frontier of their science (or art?). They had free soft drinks permanently available for the developers, brought their pets into work, kept beds under their desks for those times (not unusual) when they would work extended periods to crack a particularly intriguing bug. They had a web cam constantly updating a picture of their fish tank. They built a scale model of the Golden Gate Bridge across part of their headquarters, made entirely of soft drink cans. They embedded secret jokes into their code for the amusement of the faithful. Above all else, they were dedicated, innovative and creative. They (and all their followers) called their product Mozilla, after the cartoon lizard-like creature which was their mascot. Everyone else called their company Netscape. They were the first to develop a web search engine, at least in the form we know them today. It was based on a web browser called Mosaic written by the National Centre for Supercomputing, from where most of the original development team came. Like much of the web’s software at the time, the Mozilla browser was free, reflecting the anti-big business culture of many pioneering development groups. Maybe change was inevitable, and change it did. Commercial pressures started to curb the slightly anarchic culture of the developers. In 1998, the web cam was turned off. The company’s website became almost indistinguishable from other corporate sites. By the end of the year, Jim Clark, the CEO of Netscape, sold the company to AOL, regarded by some as the symbol of big business in the internet world. Several of Netscape’s founding developers left (setting up their own web site, www.ex-mozilla.org). As one website devoted to images of the Mozilla cartoon had it, ‘Mozilla was the mascot of the Netscape company in the early days; he gradually went away, because he was scared of the pinstriped suits.’ Process technology in design Process technology used in the design and development activity can provide very significant assistance in the process. Most of these are IT-based and an increasing number are internetbased. For example, the ability of developers to collaborate across organisations and within global networks is very much based on internet technology. Although this has presented a new set of challenges (for example, can a virtual collaborative team using internet communications ever achieve the creativity that comes from personal contact?) such technologies have 2 Original sources: O’Brien, D (2000) ‘The rise and fall of Mighty Mozilla’, Sunday Times, 10 Sept. 338 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual nevertheless provided many new opportunities. For example, the best-known process technology in product development is computer-aided design (CAD). CAD systems store and categorise product and component information and allow designs to be built-up on screen, often performing basic engineering calculations to test the appropriateness of proposed design solutions. They provide the computer-aided ability to create a modified product drawing and allow conventionally used shapes to be added swiftly to the computer-based representation of a product. Designs created on screen can be saved and retrieved for later use; this enables a library of standardised part and component designs to be built-up. Not only can this dramatically increase the productivity of the design process but it also aids the standardisation of parts in the design activity. Often CAD systems come with their own library of standard parts. Another example of process technology in design and development is simulation. One of the best-known uses of simulation for success in the sporting world came in the 1995 America’s Cup. The America’s cup is a yacht race, originally founded in 1851 by the Royal Yacht Squadron of England. An American boat won that first race and from that point the race acquired its name. American boats continued to win the race for the next 132 years until 1983 when an Australian boat, using a radical new design, captured the trophy. This focused even greater attention on to the design of the boats and the next ten years saw the incorporation of formal experimentation, testing and computer-based simulation during the design processes which were attempting to come up with world-beating yacht designs. By the 1995 contest, various potential challengers for the trophy were using different types of computer simulation to analyse the structural characteristics of a design, simulate the flow of water over the ‘critical surfaces’ and predict how the yacht would behave under different wind and sea conditions. It had been found that, although simulations were not always totally accurate, they had a number of advantages over the alternative experimental technique of using scale models in wind tunnels and towing tanks. This had proved an expensive technique and even with the large budgets available for America’s Cup yacht designs, teams could rarely afford more than 20 or so prototypes to be tested in this way. Simulation provided both faster and cheaper feedback to the designers. Unfortunately, the advanced simulation programs required a considerable amount of computing power. For this reason, teams often formed partnerships with organisations who could provide advanced computing facilities. The New Zealand team partnered with Silicon Graphics, the Australian team used the facilities of the Sun computing company and an American team obtained over $1 million worth of computer time with a group of partners that included the aircraft manufacturer Boeing and the supercomputer manufacturer Cray. The eventual winner in January 1995 was the boat designed by Team New Zealand. Not only was this one of the very few non-American boats ever to win the cup in its history, but they won by a clear 5–0 margin. Much of their success was put down to their use of simulation-based experiments during the process which culminated in their final design. Although using cycles of frequent simulation and feedback, they were careful to blend their own practical experience with the more theoretical information coming from the simulations. Dave Egan, Team New Zealand’s head of simulation, was careful to put the role of their computer-based experiments in perspective. ‘In practice, if you start with a bad design, simulation won’t get you anywhere near a good one. Some of the other (design) syndicates let. . . simulation . . . drive their process. The Australians, for example, had some really deep simulation experts, and see where that got them.’ (In one of their early races against Team New Zealand, the Australian boat sank!) 339 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Development team strategy Example – Product development at Microsoft3 Project development teams are commonly used for the organisation of development resources, with a gradual shift in the organisation of development from functionally based organisation structures to team-based structures. Take, for example, software development – an activity of increasing importance in many companies. And none more so than Microsoft, the biggest software company in the world. Here the numbers of staff involved in product development are huge, with the main problem being how to organise such a large number of staff. The software industry has, especially over the past ten years, posed new challenges for product and service development. Both user requirements and the underlying technological possibilities for software products are turbulent and difficult to predict. Furthermore, the products themselves are complex and frighteningly interconnected in their internal structure. Making changes to one part of a software product during the development process will almost certainly affect other parts, though exactly how is difficult to predict. Above all, software products are big and getting bigger. Some Microsoft products from the early 1980s had fewer than 100,000 lines of code. The first Windows NT in 1993 had about 4.5 million lines of code and Windows 95 (introduced in 1995) has 11 million lines of code. Similarly, teams of developers who once numbered 10 or 20 can now number many hundreds. At Microsoft a strategy for coping with such difficult development products has emerged. It consists of two main clusters of ideas. The first defines the approach the company takes to conceptualising the overall development task and allocating resources to its various stages. The second concerns the company’s approach to managing the development process itself on a dayby-day basis. The first part of the strategy has been referred to as focus creativity by evolving features and fixing resources. This consists of a number of ideas, including the strict prioritisation of individual features within the product, the most important being developed first. Without such prioritisation development can drag on, always a tendency in software development, especially when customer requirements and technologies are moving rapidly. Brief vision statements for each part of the project help to define more detailed functional specifications needed to determine resources, but not so detailed as to prevent the redefinition of development objectives as the project progresses. (Often feature sets can change by over 30 per cent during development). A modular architecture for the product as a whole facilitates incremental change involving the addition or deletion of individual features. An important element in this part of Microsoft’s strategy is its rule to ‘fix’ project resources early in the development process. This limits the number of people and the time available for each part of the development, encouraging the individual development teams to abandon features if development times slip (not necessarily harmful because of the strict prioritisation). It also focuses the team’s creativity towards achieving a ‘working’ (if not perfect) version of the product which can be made ready for market testing. The second part of the Microsoft strategy has been referred to as do everything in parallel with frequent synchronisations. This is an attempt to tackle the dilemma of ensuring development 3 Sources: Company documents and Cusumano, M.A. (1997) ‘How Microsoft makes large teams work like small teams’, Sloan Management Review, Fall. 340 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual discipline and order without inhibiting the developers’ creativity. Big projects do need clearly defined development phases and task allocation, but over-specifying a project structure does not encourage innovation. Microsoft uses relatively small teams of three to four hundred developers who synchronise their decisions very frequently, often every day. These synchronisations, called ‘builds’, always occur at a fixed time (usually 2 p.m. or 5 p.m.). Staff are free to work flexibly and contribute their development to the project only when they have something to add. Developers submit their work at the fixed ‘build’ time. This then allows the various bits of code to be recompiled (put together) by the end of the day or the start of the next day. Testing and debugging can then commence. This frequent synchronisation allows individual teams to be creative and to change their objectives in line with changing circumstances but, at the same time, ensures a shared discipline. Even so, it is necessary to stabilise the design periodically through the use of intermediate ‘milestones’. Each milestone marks the completion of a cluster of components. Providing such ‘finish points’ reduces the number of components being developed in parallel and makes the project easier to control. Microsoft seems to have come up with a number of ‘rules’ which help them to keep the task manageable. These are as follows: • Keep project size and scope limits clear, with limited product vision; personnel and time limits. • Make product ‘architectures’ clear and divisible through modularisation by features, functions, subsystems and objects. • Make project architectures clear and divisible through specified feature teams and milestone subprojects. • Keep a small-team structure with many small multifunctional groups with high autonomy and responsibility. • ‘Force’ co-ordination and synchronisation through daily product builds, immediate error detection and correction, and milestone stabilisations. • Encourage good communications within and across functions and teams through shared responsibilities, one site, common language and open culture. • Retail product–process flexibility to accommodate the unknown by evolving product specifications, project buffer time and evolving process. External design networks There is a trend towards outsourcing some design responsibility to external agencies. This may be an agency specialising in design, sometimes it is the company which will supply the product or service when it is in full ‘production’. So, for example, a vehicle manufacturer might choose to ask a components supplier to design the component (within specific design limits) as well as manufacture it. This means that, for many suppliers, management of knowledge and management of relationships are two issues which have become increasingly important. 341 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – Will airline passengers learn to love stealth technology? This example illustrates some of the risks involved in long-term radical product and service redesign. It describes a very real tension between what is an effective design as far as the customer is concerned (the customer in this case being the airlines who buy the aircraft) and what is an effective design as far as the final consumer is concerned (the consumer being the passengers who use the airlines services). The issue here being whether any aircraft manufacturer will invest serious money into developing a design such as the one described when there is a distinct likelihood that it will never be acceptable to consumers. Or will it? The investment decision will depend on ones view of a whole series of uncertainties. For example, the uncertainty surrounding the real cost of developing such an aircraft design, the uncertainty regarding whether such a design could ever by practical, the uncertainty regarding aircraft fuel prices (at what price of air fares will customers overcome their reluctance to use this kind of design?), the uncertainty regarding global warming and consumers’ reaction to it, etc. At some time there may come a point where the aircraft manufacturers’ subject judgement of all these uncertainties makes significant investment in this kind of design a risk worth taking. Commentary on example - IBM develops its research base in China IBM’s research facility in China illustrates how establishing such product and service development organisations in new markets can achieve two advantages. First, it provides a base from which to develop an in-depth understanding of the new market. Specialists working in a development centre have a unique potential for bringing marketing and technical issues together. Second, it can take advantage of the particular resources that may be available in that new market. In this case, it was both the level of technical expertise and education of Chinese researchers as well as their relatively low cost compared to their Western equivalents. It also provides an illustration of how, when well-managed and led, an overseas development centre can carve out an important role for itself within a worldwide network of organisations. Much of the success the Chinese centre is attributable to the vision and energy as well as the technical expertise and managerial competence of the centre itself. IBM had the foresight to ‘give them space to develop’ but it was the centre and its management that created the opportunity for themselves. 342 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 9 The process of operations strategy – formulation and implementation Chapter aims The chapter divides the process of operations strategy formulation into four stages: formulation, implementation, monitoring and control. Chapter 9 looks at the first two of these stages: formulation and implementation, while Chapter 10 examines the final two stages: monitoring and control. Our study guides 9 and 10 mirror this division. This study guide aims to • Introduce the concepts ‘formulation’, ‘alignment’ in formulation and strategic sustainability • Examine some of the methods used in formulation • Illustrate the nature of operations strategy implementation • Explain how participation can affect implementation What do we mean by ‘process’ Put simply, the chapter’s distinction between operations strategy content and operations strategy process is that… Operations strategy content is the set of decisions which a company makes (explicitly or implicitly) which shape its operations strategy (‘What shall we do?’). Operations strategy process is the method or approach they take to making those content decisions (‘How shall we decide what we do?’) So the process of operations strategy is concerned with ‘how’ to reconcile market requirements with operations resources over the long term. Yet the chapter does admit that, in practice, achieving this reconciliation (or ‘alignment’) is much more difficult than it sounds. It also makes the point that, although their simple step-by-step model of how to ‘do’ operations strategy is, in reality a ‘simplification of a messy reality’, the four stage model is useful to illustrate some of the elements of ‘process’. It is also worth noting that the majority of the book has been concerned with content, rather than process, issues. Many content decisions (such as the role and organisation of the operations function) profoundly affect the process of putting strategies together. Similarly, the approach taken to strategy formulation (not full considering competitors, for example) can influence the final content decisions. 343 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The stage model of the process of operation strategy Although the stage model of the process of operation strategy used in Chapters 9 and 10 is a reasonable representation of how operation strategies are (or should be) put together, it could be argued that a better representation should reflect the learning that (again should) occurs. Figure 9.1 shows a cyclical representation of the four stages. The idea is that the experiences and learning gained from each stage will refine each replication of the process. The formulation stage The formulation of operations strategy, according to the chapter, is ‘the practical process of articulating the various objectives and decisions that make up the strategy’. It looks at ‘how’ operations strategies are put together. Its main objective is ‘sustainable alignment’. This is the achievement of some kind of alignment, or ‘fit’, between what the market wants, and what the operation can deliver, that can be sustained over time. One can treat this objective at three levels. • Fit – achieving alignment between what the market wants and what the operation’s resources and processes are capable of giving • Sustainability – achieving fit over time either to maintain the levels of market requirements and operations capabilities at the same level or to achieve fit between the two at a higher level. • Risk – coping with the uncertainties, and their consequences, as the operation attempts to achieve alignment over time. 344 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Chapter 9 deals with the first two issues. The third (risk) is treated in Chapter 10. Taken together, the three levels involve progressively greater complexity (and become progressively more difficult to deal with at a conceptual level). Alignment? The chapter’ Figure 9.2 shows the conceptual model used to illustrate the idea of alignment. Alignment implies an approximate balance between required market performance and actual operations performance. This is represented by the ‘line of fit’ on Figure 9.1 (alternatively called the ‘line of alignment’). However, as the chapter emphasises, this diagrammatic representation is a conceptual, rather than practical model. But it does allow one to describe the various deviations from the ideal position of sustainable alignment as shown in Figure 9.2. The original position of an operation is at point X which is on the line of fit. In other words, its operations resource capabilities match the requirements of the markets that it is operating in. If the operation moves to point A this means that the requirements of the markets in which it is operating have significantly increased. This has left the operation with insufficient operations capabilities to satisfy these market requirements. If the operation moves to point B it indicates that the operation itself has suffered a loss of capability, either over time or suddenly (for example, through a catastrophic operations failure). So, like position A, it is no longer able to satisfy its markets. If the operation moves to point C it means that the operation has developed some degree of enhanced operations capabilities but for some reason these have not been exploited in its markets. To that extent the enhanced capabilities are, at the moment, wasted in terms of their impact on overall competitiveness. If the operation moves to point D, then its market requirements have significantly reduced leaving it with excess operations capabilities. This means that, like at point C, it has capabilities that are not being exploited in its markets. 345 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Moving up the line of fit – An example1 TDG plc are specialists in providing third party logistics services to the growing number of manufacturers and retailers who choose not to do their own distribution. Instead they outsource to companies like TDG, who have European logistics services operations that cover the UK, Ireland, France, Spain, Poland and Holland. Here is how their CEO, David Garman, sees the business. ‘There are a number of different types of company providing distribution services. Each with different propositions for the market. At the simplest level, there are the ‘haulage’ and ‘storage’ businesses. These companies either move goods around or they store them in warehouses. Clients plan what has to be done and it is done to order. One level up from the haulage or storage operations are the physical distribution companies, who bring haulage and storage together. These companies collect clients’ products, put them into storage facilities and deliver them to the end customer as and when required. After that there are the companies who offer contract logistics. As a contract logistics service provider you are likely to be dealing with the more sophisticated clients who are looking for better quality facilities and management and the capability to deal with more complex operations. One level further up is the market for supply chain management services. To do this you have to be able to manage supply chains from end to end, or at least some significant part of the whole chain. Doing this requires a much greater degree of analytical and modelling capability, business process reengineering and consultancy skills.’ TDG, along with other prominent logistics companies, describes itself as a ‘lead logistics provider’ or LLP, This means that they can provide the consultancy-led, analytical and strategic services integrated with a sound base of practical experience in running successful ‘on-the-road’ operations. ‘In 1999, TDG was a UK distribution company’, says David Garman, ‘now we are a European contract logistics provider with a vision to becoming a full supply chain management company. Providing such services requires sophisticated operations capability, especially in terms of information technology and management dynamism. Because our sites are physically dispersed with our vehicles at any time spread around the motorways of Europe, IT is fundamental to this industry. It gives you visibility of your operation. We need the best operations managers, supported by the best IT’. So, why is David Garman moving TDG towards providing more sophisticated services to clients? The answer is that there is usually more profit to be made from providing complex services than simple ones. The problem with any company that produces simple products or services is that any other company can also do it. Therefore, because other companies have similar operations capabilities, prices will drop as each company tries to undercut the other. Conversely, products and services (such as sophisticated supply chain distribution services) are far more difficult to create. This means that only the companies with the required resources and experience can provide such services. And if a company has few competitors it can more easily maintain higher prices and (hopefully) high margins. David Garman is moving towards providing more sophisticated services because it is more profitable for him to do so. However, the main problem with trying to provide sophisticated products and services is that they are difficult to create. Companies providing such products and services, therefore, are likely to be operating at the limit of their capability. Under these circumstances it is more likely that the company will make mistakes. The main danger with TDG’s strategy is that it tries to 1 Original example from Slack et al. (2010) Operations management, Financial Times Prentice Hall 346 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual offer sophisticated services before it has developed appropriate operations capabilities. Figure 9.3 fits David Garman’s description of his industry into the ‘line of fit’ model. Starting with requirements or operations resource capabilities The chapter goes to some length in explaining how the process of formulating an operations strategy to achieve alignment can be completed in two different ‘directions’, either starting with requirements or operations resource capabilities. In Figure 9.4, the ‘stage models’ of how strategies should be put together that are implied by the two starting points for operations strategy formulation are illustrated. Remember though, the chapter does emphasise that starting from market requirements and working inwards towards identifying appropriate operations capabilities that should be developed is far more common that starting with operations capabilities and then attempting to seek markets where they can be profitably exploited. Again, as the chapter points out, this is not surprising since all businesses have market but not all businesses necessarily have capabilities that are worth exploiting in the market. 347 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – Clean and Green (CAG) Recycling Services In the CAG case, first-mover advantage in a specific geographical area effectively locked out other competitors. In resource terms, the distribution of dedicated recycling facilities (i.e. specially designed receptacles for paper) proved an effective barrier to entry. This expensive strategic decision was inspired by the successful deployment (albeit one that has subsequently caused a great deal of legal furore) of proprietary freezers by the ice cream industry. The early contractual arrangements with suppliers reduced their bargaining power (and effectively prevented them from moving upstream into this business) and the deliberate co-production between CAG and its clients of an environmental reputation also reduced their bargaining power. Nevertheless, despite all the barriers to entry and imitation that CAG created and/or exploited during their ‘start-up’ phase, their growth plans required them to enter new markets and develop both related and entirely new capabilities. This required them to actively embrace risk and uncertainty, especially with their later strategies which anticipated future legislation. Figures 9.5–9.8 illustrate CAGs development over time. 348 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual 349 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Figure 9.7 Operations strategy matrix for CAG Recycling Services as they anticipated future recycling legislation 350 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Formulation methods Without a firm intellectual understanding of the issues involved in putting operations strategies together, the process can become at best superficial or at worst misleading. Yet operations strategy formulation is essentially a practical exercise. It answers a very basic question: ‘what are we going to do to ensure that an operation contributes to the whole organisation?’ And a first step in getting close to an answer to this question must be to gather and analyse information that will form in the inputs to the formulation process. However, this is not always a straightforward process. Both information regarding market requirements and operations resource capabilities is rarely straightforward. Surprisingly, few firms (even if they recognise this importance) have any idea about how to create an operations strategy. Although in the broader field of corporate and business strategy there are many practical formulation models, they remain relatively rare in operations. This may seem somewhat surprising (given the essentially practical nature of the operations discipline) but arguably reflects the fact that operations strategy is simply more difficult to formulate. Three specific reasons can be put forward to explain this: • Operations inevitably have the largest number of internal and external interfaces and any strategy will have to deal with this enhanced complexity • Many organisations see no competitive role for their operations and therefore no need for a separate strategy • The ‘lower status’ associated with operations has meant that operations managers have been viewed as having no strategic role and often lacked any strategy formulation experience However, some models for formulating operations strategy are relatively well known, and we will describe two of the main methods. Both these (Hill and Platts/Gregory) were originally intended for manufacturing organisations but in general the techniques they encompass are relevant to service firms as well. The Hill framework One of the first, and certainly most influential, approaches to operations strategy formulation (although once again its development is largely connected with manufacturing operations) is that devised by Professor Terry Hill. The ‘Hill framework’ is illustrated in Figure 9.9. Hill’s model, which is here adapted to the terminology used in the chapter, follows the well-tried approach of providing a connection between different levels of strategy making. It is essentially a five-step procedure. Step one involves understanding the long-term corporate objectives of the organisation so that the eventual operations strategy can be seen in terms of its contribution to these corporate objectives. Step two involves understanding how the marketing strategy of the organisation has been developed to achieve corporate objectives. This step, in effect, identifies the products/service markets which the operations strategy must satisfy, as well as identifying the product or service characteristics such as range, mix and volume, which the operation will be required to provide. Step three translates marketing strategy into what we have called performance objectives. These are the things which are important to the operation in terms of winning business or satisfying customers. Hill goes on to divide the factors that win business into order-winners and qualifiers (this distinction was explained study guide 2). Step four is what Hill calls ‘process choice’. This is similar, but not identical, to the chapter’ decision areas of capacity, supply networks and process technology. The purpose is to define a set of structural 351 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual characteristics of the operations which are coherent with each other and correspond to the way the company wishes to compete. Step five involves a similar process but this time with the infrastructural features of the operation (broadly what we have called ‘development and organisation’ decisions). Hill’s framework is not intended to imply a simple sequential movement from step one to step five, although during the formulation process the emphasis does move in this direction. Rather, Hill sees the process as an iterative one, whereby operations managers cycle between an understanding of the long-term strategic requirements of the operation and the specific resource developments which are required to support strategy. In this iterative process, the identification of competitive factors in step three is seen as critical. It is at this stage that any mismatches 352 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual between what the organisation’s strategy requires and what its operation can provide become evident. The steps in the Hill framework are closely related to classic corporate planning methodologies (with clear separations of responsibility, strong functional tasks, etc.) but Hill argues that whereas the first three elements are treated as interactive and iterative, the final two are commonly presented as straightforward, linear, logical implementation issues. By stressing the iterative nature of his framework, Hill emphasises the need to improve the critical relationship between operations and marketing (too often a ‘fault-line’ in businesses) and facilitates this process by providing a framework that helps to simplify the complexity of manufacturing operations. This is essentially a mechanism for ensuring the coherence and correspondence of the overall strategy. Furthermore, he stresses that these reviews should not be static in so far as they should consider both existing products and plans for future products. This allows considerations of product (and process) life cycle to be included. With finite resources available, the framework can highlight some of the trade-offs that exist in any operations strategy. The Hill methodology was one of the first and certainly most influential models that fully address the issue of operations strategy and the difficulties associated with the formulation process. However, it is more than 20 years old and a number of critical issues need to be highlighted. • Although many of the core issues addressed by the framework are equally applicable to a service environment, the basic concepts and underpinning research are derived from a manufacturing environment and a certain bias is inevitable. • The framework attempts to translate external, market driven requirements into their implications for internal resource development. However, as described in the first study guide, establishing ‘fit’ is not the only competitive role for operations. The Hill framework is firmly entrenched in a top-down marketing-led view of corporate strategy • Hill’s methodology does not distinguish between external ‘competitive factors’ and internal ‘performance objectives’ The Platts–Gregory procedure Whilst the Platts/Gregory framework is also manufacturing-focused and adopts a similar, topdown view of strategy, it is much more concerned with the practical nature of formulating a strategy whilst actually running day-to-day operations. It also involves identifying those factors that are required by the market and then explicitly comparing them to the level of achieved performance in the operation. Although superficially similar to the Hill framework, the work of Ken Platts and Mike Gregory of Cambridge University adds at least one crucial element missing from Hill – namely a form of prioritisation based upon an assessment of relative, competitive performance. The overall framework comprises three distinct stages (see Figure 9.10). Stage 1 involves developing an understanding of the market position of the organisation. Specifically, it seeks to identify the factors that are ‘required’ by the market and then compares these to a level of achieved performance. Stage 2 seeks to identify the capabilities of the operation. Decision categories (similar to those developed by Hayes and Wheelwright) are provided to help managers classify current operations practice and then link these practices to the priorities identified in Stage 1. 353 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Stage 3 is the least structured of the elements, encouraging managers to review the different options they have for improvement and developing a new operations strategy – against the backdrop of market criteria. Like many of the practical quality methodologies, the Platts–Gregory procedure develops a ‘gap-based’ model for driving improvement. Here the gap is between customers’ view of what is important and the way in which the operation actually performs. In this way it is similar to the importance–performance matrix. But instead of a matrix the procedure uses profiles of market requirements and achieved performance to show up the gaps which the operations strategy must address. Figure 9.11 illustrates the use of these profiles. 354 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Platts/Gregory employ a similar conceptualisation of operations strategy to that described in Hill and it is therefore in the area of practical applicability. Where their greatest, and in some ways still unique, contribution lies in the use of worksheets, project management guidance etc. However, a number of problems still have to be highlighted: • Once again the exclusive focus of their work is manufacturing operations and although the concepts are transferable, the language and examples given do not facilitate this process • They retain the same view ‘outside-in’ marketing-led view of business strategy • The final stage of the process is arguably the most important because it is here that the ‘what happens now’ questions are addressed. Unfortunately, it is here that the framework is at its least prescriptive and weakest. 355 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – IBM falls victim to a reluctance to change2 The way in which IBM fell from grace during this period is something of a classic story. It is often used by business academics to illustrate how reluctance to change and a failure to understand the emerging needs of a changing market can cripple a company. And it is true that it is a cautionary tale that shows how vulnerable even the largest corporations are to emerging technologies and changing markets. When the environment of any business is turbulent, even relatively small mistakes can come close to destroying a business. But what the example in the chapter does not go on to say is that IBM has emerged from this very troubled period to be, once again, a successful and dynamic company. It has done this partly by coming to terms with the reality of the new market for computing services and partly by restructuring its operations resources to meet those new demands. For example, in recent years IBM's strategy has been to move away from old-style hardware and decrease its reliance on its large technology services arm by focusing on developing markets and the high-margin market for corporate software. IBM’s software business is the second-largest in the world behind Microsoft’s (2007 data). According to the IBM’s chief executive Sam Palmisano , ‘strong growth in the middleware market made it likely that the software division would account for about half of IBM's profit markets by 2010. IBM employs more than 53,000 people in India, and 10,000 each in China, Brazil, by 2010. The irresistible forces of globalisation will help IBM double its revenues from emerging Russia and eastern Europe. Look at this extract from one of IBM’s press releases. IBM will on Tuesday unveil plans to offer its “Jamming” in-house technology to companies and organisations in an effort to build a business out of their need to communicate with thousands of employees in online brainstorming sessions. The launch of the product – born out of Big Blue's desire to listen to 300,000 staff around the world – underlines the challenge faced by companies seeking to keep in touch with a diverse, dispersed workforce. It also shows how technology companies are exploiting the internet's popularity by grafting their own proprietary tools onto the worldwide web. IBM hopes that the “jams” – named after the spontaneous riffing of jazz musicians – can be sold to companies that want to involve employees in crucial issues such as merger integration, corporate strategy and their relationship with customers. IBM says that it has already received requests for jams from companies in the financial services, telecommunications and packaging services sectors. The jams, which will begin next week with an event for the ailing US car parts industry, enable thousands of employees to give opinions on specific topics via the internet over several days. "It is a very democratic process. Everyone has the same voice," said Liam Cleaver, head of IBM Jams. "It really pools the brain power of the organisation." Unlike instant messaging and virtual chat rooms, jam participants are not anonymous and are monitored by IBM technology that enables management to pick out specific themes, ideas and grudges from the cacophony of the online dialogue. The search tool was used by IBM for a 2003 jam that saw more than 50,000 employees, including Sam Palmisano, help the company rewrite its corporate values.” The exercise had proved that modern companies could not prosper without grassroots input”, said Mr Palmisano. 2 F. Guerrera, (2007), IBM to offer corporate Jamming, Financial Times, Feb 26, and F. Guerrera (2007), IBM to switch focus to software division, Financial Times, May 17. 356 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual The implementation stage The second stage of the four-stage model of operations strategy process is concerned with implementation. That is ‘the way that strategies are operationalised or executed’. It includes, they say, ‘the processes that attempt to ensure that strategies are achieved. Implementation is an important part of operations strategy because, ‘strategy remains only a document until it has been implemented’. Implementation then, is the realisation of an application, or execution of a plan, idea or policy. In the context of operations strategy, implementation means the organising of all the activities involved in making the strategy work as intended. Yet there is a view that implementation is something of a forgotten issue in, not only in the strategy literature generally, but also surprisingly, in operations strategy. Surprising, because operations is where implementation usually happens. One relatively comprehensive study of 160 companies over a 5-year period investigated what contributes to company success.3 In this study, success was strongly correlated, among other things, with an ability to implement strategy. Factors such as culture, organisational structure and aspects of operational implementation were vital to company success, with success measured by total return to shareholders. Commentary on example – Implementing Renault’s Romanian strategy One could use this example both to illustrate the nature of fit in devising an operations strategy that is compatible with market requirements, and to illustrate how the implementation of that strategy must also be compatible with the overall intention of the strategy. So, clearly the idea of building a low cost automobile for the European market has a high degree of fit with the types of technology used and the location of the factory etc. From an implementation point of view there are a number of decisions made by Renault that follow on from this strategy. 3 • The company had to decide whether to exploit the rather mixed capabilities of an existing Eastern European auto plant or to build a greenfield site, possibly in a similar location. They decided on the former but recognised that the implementation would have to be managed in a particular way. For example, they put significant effort into communicating their long-term intentions and commitment to the area even though they were obliged to shed more than half their labour force. • Some of the detailed design decisions of the car were chosen to assist implementation, for example, the use of flat glass in the windshield • Local suppliers where used where possible, possibly partly to emphasise Renault’s commitment to the region in the longer term • The decision to use relatively few robots because of difficulty in supporting such technology locally is significant. It does not mean that robots are necessarily inappropriate, nor does it mean that they will never be used in this site. Rather it was an implementation decision that recognised the limitations of what could be done in the short term. William Joyce, Nitin Nohria, and Bruce Roberson, (2003) What (Really) Works, Harper Business. 357 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Participation in operations strategy implementation The chapter makes the fairly obvious point that organisations that want to be successful at implementation must always consider the aspects of organisational behaviour that actually make strategies happen. This has a number of elements, amongst which may be the following: • They should understand the impact that the strategy could have on individual’s and groups’ working circumstances • They should be aware of the effects a new strategy will have on human resource needs (the number and skills of staff for example) • They should understand how much change the strategy implies and how quickly that change must be provided • They should be able to articulate the strategy so that those charged with developing the corresponding action develop a full understanding of the strategy so that they can further develop the tactics necessary for implementation • They should think about the organisation's communication needs Of course this is not a comprehensive list. Moreover, the whole subject of participation and involvement in the implantation process is huge with a rich literature and body of knowledge. Many aspects of this subject are fully covered in other courses, so we will not dwell on this area (important though it is) extensively. Nevertheless two points are worth making here. The first is that there are many frameworks in the strategy literature that are worth revisiting to gain useful perspectives on implementation, even if the framework originally had a wider purpose For example, the ‘well established’ (in other words, quite old) 7S framework. The second point is that many organisations already have some kind of improvement mechanism in place that can be the vehicle for implementation. GE’s ‘Workout’ is described as an example of this. Commentary on example – Dell (part 2) Things change OK? Don’t write off Dell yet. This example in the chapter should be taken as a warning of how ‘core rigidities’ go along with core competencies. It is certainly intended to be Dell’s obituary. Nevertheless, there are some points which are worth thinking about from Dell’s dilemma. Clearly its investment in a radically different supply chain configuration, although it gave it significant advantage in its early days, is now proving to be less than ideal for the new markets. When the radical supply chain model was set-up, it was not at all obvious that the market would change in the way that it has with a far greater emphasis on design aesthetics and the merging of computing and entertainment products. To some extent, the market has changed because of the action of competitors, most notably Apple who have educated consumers to the importance of good aesthetic design. It is difficult to untangle two issues, both of which may explain Dell’s dilemma. The first is the lack of fit between the company’s supply chain configuration and the way markets are moving (as mentioned previously). The second is that Dell, unlike its early days, is a large and mature company which may have lost some of its cutting edge simple because of the growth that has come from its previous success. 358 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual GEs ‘Work-out’ GE’s publicity has it that Jack Welch wanted a mechanism to harness his belief that employees were an important source of brainpower for new and creative ideas. He ‘wanted to create an environment that pushes towards a relentless, endless companywide search for a better way to do everything we do.’ Further, he believed that in most organisations, change efforts come and go and rarely make a real difference. But in GE, which is one of the largest companies in the world, they say that one particular change process has helped to start ‘a complete transformation’. It is known as Work-out. The Work-out program was devised as a way to reduce bureaucracy and give every employee, from managers to factory workers, an opportunity to influence and improve GE's day-to-day operations. The program was named because Welch had talked about ‘working out’ the nonsense of GE, and dealing with problems that had to be ‘worked out’. Work-out was designed to ‘reduce and ultimately eliminate all of the waste hours and energy that organisations like GE typically expend in performing day-to-day operations’. As Welch put it, ‘Work-out is meant to help people stop ‘wrestling’ with the boundaries, the absurdities that grow in large organisations. We're all familiar with those absurdities: too many approvals, duplication, pomposity and waste.’ Like many ‘high profile’ improvement and implementation approached, Work-out is neither totally new nor is it a particularly complicated idea. All it involves is getting groups of stakeholders, (staff, management, sometimes internal or external customers and suppliers) together to brainstorm problems and generate solutions. However, GE took this simple idea much further, using structured processes, Work-out ‘Town Meetings’ and so on. Essentially though, it remains a simple concept based on the idea that those closest to the work know it best. When these people’s ideas, whatever their roles, are encouraged and turned into action, creative solutions often emerge. However, anyone with any experience of this type of ‘branded’ approach knows the dangers of exhortation-based methods that over-promise and often underdeliver. Certainly with ‘Work-out’ there have been examples of naïve senior managers being sold the approach, probably add it to the existing bundle of half thought out initiatives already current in the organisation and expecting it to ‘transform’ their business. This is not to say that Work-out or any other similar approach is necessarily doomed to failure, but it all too often is abused. The point here is that any attempt to harness staff in the implementation of operations strategies should take account of any existing mechanisms such as Work-out. If not, the implementation may simply become yet another initiative. 359 © Nigel Slack and Michael Lewis 2012 Study guide CHAPTER 10 Monitoring and control Introduction Study guide 9 examined the first two of the four stages of operations – strategy process; formulation and implementation. This study guide looks at the final two stages – monitoring and control. Figure 10.1 in the text shows how these two stages fit into their four-stage model. But note the point we made in the previous study guide for Chapter 9, a better way of thinking about the process of operations strategy is a cyclical model. Doing this emphasises a more continuous set of activities. This idea is shown in Figure 10.1. This study guide aims to: • Examine the differences between operational and strategic monitoring and control. • Look at how progress towards strategic objectives can be tracked. • Describe the dynamics of monitoring and control, especially in terms of how monitoring and control attempts to control risks. • Explain how learning and stakeholder management contribute to strategic control. 360 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Monitoring and control at a strategic level Before examining the separate stages of strategic monitoring and control, the chapter discusses the joint purpose of these two stages. They make a number of important points. • Any monitoring and control procedure should provide an early indication (a ‘warning bell’ they call it) that corrective action may be needed. • It should be capable of diagnosing data and triggering appropriate changes in how the operations strategy is being implemented. • Although a strategic view of monitoring and control is similar to how it works operationally, it is less obvious. • Several assumptions underlying an operational view of monitoring and control do not necessarily apply at a strategic level. • In particular, • Are strategic objectives clear and unambiguous? • Is that there is some reasonable knowledge of how to bring about the desired outcome (in other words, is there significant uncertainty that cannot be entirely eliminated)? • What is the frequency with which control interventions are made? The chapter then adapts work first expounded by Professor Geert Hofstede to develop a typology of control that moves from relatively straightforward control through increasingly more complex and ambiguous states. Their types of control are as follows. • Routine control – Where objectives are unambiguous, the effects of interventions are known and activities are repetitive. • Expert control – If objectives are unambiguous, yet the effects of interventions relatively well understood, but the activity is not repetitive, control can be delegated to an ‘expert’; someone for whom such activities are repetitive because they have built their knowledge on previous experience elsewhere. • Trial-and-error control – If strategic objectives are relatively unambiguous, but effects of interventions not known, while, however, the activity is repetitive, the organisation can gain knowledge of how to control successfully through its own failures. In other words, although simple prescriptions may not be available in the early stages of making control interventions, the organisation can learn how to do it through experience. • Intuitive control – If strategic objectives are relatively unambiguous, but effects of interventions not known, nor is strategic decision making repetitive, learning by trial and error is not possible. Therefore, the organisation has to view strategic control as more of an art rather than as a science. And in these circumstances, control must be based on the management team using its innate intuition to make strategic control decisions. 361 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Negotiated control – The most difficult circumstance for strategic control is when objectives are ambiguous. This type of control involves reducing ambiguity in some way by making objectives less uncertain and resolving ambiguities so that external uncertainties become internal certainties. Using the model To illustrate how the nature of strategic monitoring and control will differ depending on the nature of the strategic implementation, think through the following three brief examples. Example A – Building and running an international games event (The Bigton Games) The Games Delivery Authority (GDA) is a public body responsible for developing and building the new venues and infrastructure for the ‘International Games’ and their use after the event. After construction, the games will be staged and hosted by the Bigton Organising Committee of the Games and Paralympics Games, a private sector company. After the games, the Games Park Legacy Company (GPLC) will be responsible for ensuring the Games deliver positive changes for the area. The GDA appointed a consortium as Managing Contractor on the site, with responsibility for the Games Park and Athletes Village. The consortium is responsible for the overall programme’s quality, delivery and cost management in addition to health and safety, sustainability, equality and diversity targets. The 202-hectare Games Park itself in East Bigton, will be a $14.7bn largely public-funded construction programme spreading across five separate Bigton local government areas. Additionally, there will be other sites under construction in the area including transport developments, retail areas and local regeneration projects. But in many ways the most noteworthy aspect of the project is its emphasis on sustainability. From its inception, sustainability was central to the Bigton Games. It is to be the first Host City to embed sustainability in its planning right from the start. ‛They were', said the GDA, 'aiming to set new standards, creating positive, lasting change for the environment and communities.... "Sustainability" is far more than being "green". It's ingrained into our thinking – from the way we plan, build and work, buy, to the way we play, socialise and travel; ultimately everything that we do.' The sustainability agenda also included using the Bigton River as an environmentally friendly and economic way of moving materials across Bigton to construction sites, minimising greenhouse gas emissions, minimising waste at every stage of the project and ensuring no waste is sent to landfill. To ensure they stuck to commitments, the GDA set up an independent body (the Commission for a Sustainable Bigton 2015) to monitor the project. The GDA determined that all construction and operations bids would be judged on a 60/40 split between quality and price. Quality criteria not only included the usual timing, delivery, specification and consistency factors but also included some very demanding sustainability criteria. All potential contractors tendering for parts of the project were aware that a major underlying objective of the Games initiative was regeneration. The Games site was to be built on highly industrialised and contaminated land. So extensive land remediation would be required involving both soil processing and offsite disposal. The planning application had to include details of how all materials, including contaminated materials, would be dealt with. It was also clear that the sustainability (carbon footprint) of sourced materials was particularly important for the GDA. Closely related to this was the issue of logistics, that is, how materials were transported to and from the site which again would be judged not only on price but also in terms of carbon footprint. Providing sustainable materials in a sustainable delivery mode were considered essential to provide differentiation in the tender process. 362 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Example B – Commissioning a new high-tech distribution centre The supermarket’s new logistics boss, was blunt in his assessment of its radical supply chain implementation. ‘Our rivals have watched in utter disbelief' he said. ‘Competitors looked on in amazement as we poured millions into implementing new IT systems and replaced 21 depots with a handful of giant automated 'fulfilment factories'. The supermarket had first devised their strategy for a new faster and more efficient supply chain strategy 5 years ago when their former chief executive signed a £2 billion 7-year contract with a business services firm (Brenture), to modernise its IT and take on 800 of its staff. The problem turned out to be how they put their strategic objectives into practice. It was a huge project, with highly automated facilities and totally reconfigured IT systems. Eventually, the cost reached £3.4bn over 4 years, with new technology installed across all the company’s distribution network. Yet, during this time the company slipped into third place in a market that it once led. ‘In hindsight, the heavy reliance on automation was a big mistake, especially for fast moving goods’, said the company’s CIO. 'When a conventional facility goes wrong, you have lots of options. You have flexibility to deal with issues. When an automated "fulfilment factory" goes wrong, frankly, you're buggered.' Most damming was the way that the supermarket pressed on with the implementation of the automated facilities before proving that the concept worked at the first major site. ‘I'd have at least proved that one of them worked before building the other three’, he said. ‘Basically, the whole company was committed to doing too much, too fast, trying to implement a seven-year strategy in a three-year timescale.’ One industry analyst claimed that the supermarket just tried to do too much at the same time, reconfiguring its logistics, reducing the number of distribution sites, increasing the scale of the remaining operations, implementing a totally new over-complex IT system, outsourcing its dayto-day running, installing radical and largely untried automation and so on. And soon the supermarket’s Chief Executive had admitted the scale of the problem. 'Our supply chain systems and automated depots are not fully operational. And the IT systems that were built to back up that have not delivered,' he said. 'The IT cost is a greater proportion of sales than they were three years ago. The system was developed to account for stock but the system can't see the stock on the shelves. The problems happen most often when we revamp a range. The system could not allocate the range because it could not see that we had taken old stock off the shelves. Every store is now going to manually update the stock levels on its shelves’. Example C – Launching a new product 'It’s impossible to overemphasise just how important this launch is to our future', said the CEO. 'We have been losing market share for seven quarters straight. Traditionally, we have managed to secure more than 40 per cent of what is a hypercompetitive market. However, we have very high hopes for the new XC10 unit.' And most of the firm’s top management team agreed with her. Clearly the market had been maturing for some time now, and was undoubtedly getting more difficult. New product launches, mainly from Taiwanese competitors, had been eroding both market share and absolute volumes. Yet competitors’ products were not always technically superior. At best, they simply matched the firm’s offerings in all benchmark tests. That was what was so frustrating. 'What can we do?' said the firm’s Development Vice President. 'Unless someone comes up with a totally new technology, which is very unlikely, it will be a matter of making marginal improvements in product performance and combing this with well targeted and coordinated marketing. Fortunately, we are good at both of these. We know this technology, and we know these markets. We are also clear what role the new XC10 should play. It needs to 363 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual consolidate our market position as the leader in this field, half the slide in market share, and reestablish our customers’ faith in us. Margins, at least in the short term, are less important'. All three of these examples are important implementations for their organisations. But they do vary in terms of the degree of difficulty they pose and the nature of how the implementations need to be managed. Table 10.1 summarises the key questions used in the chapter’s modified Hofstede model. Example Clear, unambiguous objectives? Process knowledge complete? Activity repetitive? Type of monitoring and control? Example A – Building and running an international games event (The Bigton Games) Not very clear. Conflicts between public and private, long-term and short-term objectives. A ‘political’ and a ‘political’ project. Some individual elements are well understood, others less so. Some issues of ‘environmental sustainability’ not well understood. Some elements have been managed previously, but these stakeholders are unlikely to repeat a project of such complexity. Overall probably negotiated with some elements of intuitive and trial and error monitoring and control. Example B – Commissioning a new high-tech distribution centre Fairly clear objectives. Complex, but not ambiguous. Not very well understood. Big changes in technology, operations capacity structure and organisation happening simultaneously. Probably not for this company, but elements of the implementation will have been done before (by somebody). Overall probably intuitive with some elements of trial and error and expert monitoring and control. Reasonably well understood technology and markets. It sounds as if they have done this before and will do it again. Overall a reasonably routine monitoring and control task with some elements of trial and error. Example C – Very clear Launching a new objectives. The product implementation is very important, but that is not the same as being unclear. The modified Hofstede model introduces the idea that organisational context is important in monitoring and controlling implementations. And organisational designs have indeed been changing in response to the dual, and often conflicting, pressures of serving turbulent markets, whose requirements are continually changing, while at the same time preserving, and even extending, the essential capabilities that enable them to differentiate themselves from competitors. The organisation’s structure is therefore not just the context of the implementation process, it also represents the corporate memory of how strategy has shifted and accommodated to these pressures over time. And how we illustrate organisations says much about our underlying assumptions of what an ‘organisation’ is and how it is supposed to work. For example, the illustration of an organisation as a conventional ‘organogram’ implies that organisations are neat and controllable with unambiguous lines of accountability. Even a little experience in any organisation demonstrates that rarely, if ever, is this the case. Nor does it take much more experience to question whether such a mechanistic view is even appropriate, or desirable. In fact, seeing an organisation as though it was unambiguously machine-like is just 364 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual one of several metaphors commonly used to understand the realities of organisational life. One well-known analysis by Gareth Morgan proposes a number of ‘images’ or ‘metaphors’ that can be used to understand organisations1. Some of these are listed below. As you read them, try to associate them with the types of monitoring and control identified in 'The chapter’ modified Hofstede model. Organisations are machines – the resources within organisations can be seen as ‘components’ in a mechanism whose purpose is clearly understood. Relations within the organisation are clearly defined and orderly, processes and procedures that should occur usually do occur and the flow of information through the organisation is predictable. Such mechanical metaphors are popular because they appear to impose clarity on what is usually seen as deviant, messy behaviour within the organisation. Indeed, where it is important to impose clarity (as in much operations strategy analysis) such a metaphor can be useful. It is, however, a particularly limiting way of thinking about organisations. Flexibility and creativity are not emphasised, nor is independence of thought or action. Organisations are organisms – organisations are also living entities. Their behaviour is dictated by the behaviour of the individual humans within them. Individuals, and therefore the organisation, adapt to circumstances just as different species adapt to the environmental conditions in which they need to survive. The organism image helps us to understand how organisations interact with their environment, work through their life cycle and relate to other ‘species’ of organisation. This is a particularly useful way of looking at organisations if parts of the environment (such as the needs of the market) change radically. The survival of the organisation depends on its ability to exhibit sufficient flexibility to respond to its environment. However, the natural environments in which real organisms live are reasonably well understood, and are independent of the views of the organism itself. The social and political environment in which organisations exist is partly a function both of how they act and how they choose to see the environment. Organisations, even in the same industry, may see the opportunities and threats in very different ways. Organisations are brains – organisations process information and make decisions. No machine, or perhaps even organism, comes close to the degrees of sophistication of which a human brain is capable. Organisations, like brains, make decisions. They balance conflicting criteria, weigh up risks and decide when an outcome is acceptable. They are also capable of learning, changing their model of the world in the light of experience. This emphasis on decision making, accumulating experience and learning from that experience is important in understanding organisations. Brains, like organisations, are capable of developing and of organising themselves. However, organisations are clearly not unitary entities like brains. They consist of conflicting groups where power and control are key issues. Organisations are cultures – an organisation’s culture is usually taken to mean its shared values, ideology, pattern of thinking and day-to-day ritual. Different organisations will have different cultures stemming from their circumstances and their history. Because an organisation’s internal structure and view of itself are influenced by its culture, we can think of an organisation as an expression of its culture. A major strength of seeing organisations as cultures is that it draws attention to their shared ‘enactment of reality’. Within this, the symbolism present in processes and procedures is seen to be important. Looking for the symbols and shared realities within an organisation allows us to see beyond whatever that organisation may formally say about itself. Unfortunately ‘culture’ has, in many organisations, come to be 1 Morgan describes these and other metaphors in Gareth Morgan (1986) Images of Organization, Sage. 365 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual seen as something that can be changed at whim. Although managers can influence the evolution of culture, they cannot control it as if it were an air conditioning unit. Organisations are political systems – organisations, like communities, are governed. The system of government is rarely democratic, but nor is it usually a dictatorship. Within the mechanisms of government in an organisation are usually ways of understanding alternative philosophies, ways of seeking consensus (or at least reconciliation) and sometimes ways of legitimising opposition. Individuals and groups seek to pursue their aims through the detailed politics of the organisation. They form alliances, accommodate power relationships and manage conflict. Formal structures of authority may not always reflect the reality of influence and power. Such a view is useful in helping organisations to legitimise politics as an inevitable aspect of organisational life. However, seeing organisations exclusively as political systems can lead to cynicism or the pursuit of organisational power for its own sake. Although there is no direct equivalence between Morgan’s ‘metaphors’ and the chapter’s modified Hofstede model types, they follow a similar progression. As the required type of monitoring and control moves from simple ‘routine’ through to ‘negotiated’ control, so the implicit metaphor for the organisation moves from ‘organisations as machines’ through to ‘organisations as political systems’; see Figure 10.2. Performance tracking After dealing with the broader issues of monitoring and control, Chapter 10 starts to focus on the monitoring (or ‘tracking’) activity. The argument is that firms should invest in tracking performance, interpreting information and responding appropriately, especially when their environment is changing rapidly. Doing this successfully involves: • Tracking the appropriate aspects of the implementation so that progress can be assessed. • Comparing progress against targets. 366 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • Coping with any risks faced. While not repeating the text, there are some points worth emphasising. The Red Queen effect The constant battle to survive in a competitive marketplace reflects an almost biological view of competition (if you have the superior capabilities, you will probably survive, but it won’t get any easier!). Once practical and theoretical discussions turn to questions of sustainability and long-run survival in a competitive environment, the comparisons with biology become apparent. There is, for instance, a whole field of academic study called evolutionary economics that draws explicitly on concepts from the biological sciences. One of the most widely employed metaphors, and one that is described in the text, is that of the ‘Red Queen’ effect. Simply described, this holds that any species (or firm) that wishes to continue fitting in with its environment it can never relax. The struggle for survival is continual and never gets easier. As the fictional Red Queen puts it,’ it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast’. Implementation difficulty Some implementations are more difficult than others because of their scale, uncertainty and complexity. This is illustrated in Figure 10.3. Large-scale implementations involving many different types of resources with durations of many years will be more difficult to manage, both because the resources will need a high level of management effort, and because implementation objectives must be maintained over a long time period. Uncertainty also affects implementation. Very novel implementations are likely to be especially uncertain with ever-changing objectives, leading to planning difficulty. When uncertainty is high, the whole implementation process needs to be sufficiently flexible to cope with the consequences of change. Similarly, implementation projects with high levels of complexity, such as multi-organisational projects, often require considerable control effort. Their many separate activities, resources and groups of people involved, increases the scope for things to go wrong. Furthermore, as the number of separate activities in a project increases, the ways in which they can impact on each other increases exponentially. This increases the effort involved in monitoring each activity. It also increases the chances of overlooking some aspect of the implementation which may be deviating from the plan. Most significantly, it increases the ‘knock-on’ effect of any problem. 367 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Implementation risk The line of fit model is also useful to illustrate that moving up the line of fit (which is often the intention of implementation) can occur in different ways. As the chapter points out, deviating from the line of fit is both inevitable at some point and risky when it happens. This allows us to generalise about how different implementation philosophies carry different types for risk. In Figure 10.4 two paths are shown, each moving an operation from point A to the more ambitious point B. The upper path represents an implementation that is, in effect, making (implicit or explicit) promises to the market before its operation is capable of meeting those promises fully. Managing risk in these circumstances involves both managing the understanding and expectations of the market carefully and maximising the learning within the operation so that capabilities are developed as fast as possible. This is sometimes done when an organisation deliberately uses market pressure to motivate its operations to improve. The lower path represents an implementation that is committed to developing its internal capabilities before exploiting them in its markets. Managing risk in these circumstances involves ensuring that the capabilities being developed really do have value in the market, and ensuring that the organisation has the ability to appropriate value from those capabilities when the time comes. Also note how this idea of implementation exposing the firm to external (upper path) or internal (lower path) risks is similar to the previous discussion regarding how operations strategy can make firms either better than, or different from, their competitors. 368 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Controlling risk Perhaps the most useful advice regarding implementation risk from Chapter 10 is to fully consider three areas during the implementation of any operations strategy. These three areas are as follows: • Prevention – where an operation seeks to completely prevent (or reduce the frequency of) an event occurring – the question being, 'what can we do to prevent events with negative consequences occurring?' • Mitigation – where an operation seeks to isolate an event from any possible negative consequences – the question being, 'what can we do to prevent (or minimise) the negative consequences, if a potentially negative event occurs?' • Recovery strategy – where an operation analyses and accepts the consequences from an event but undertakes to minimise or alleviate or compensate for them – the question being, 'what would we do to recover from a negative consequence should one occur?' Cognition, context and control Taking a ‘risk’ perspective on the process of operations strategy implementation both adds a greater richness to the formulation activity and allows us to judge operations performance from a more realistic standpoint. But individual managers will often see risk in different ways. They will also attempt to manage it in different ways. To understand possible responses to risk in operations strategy we need to consider three sets of factors. 369 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual • First, an operations strategy must consider how the real ‘actors’ in the operations (managers and staff, as well as current and potential customers, regulators, etc.) view risk. It is their cognition of risk which is significant because individuals do not always deal with risk in a rational manner. • Second, our perception of risk is strongly influenced by its business context. Therefore the internal (operations system) and external (customer and stakeholder) circumstances must be taken into account. • Third, because by definition a risk is something with unwanted consequences, it is something that we normally seek to control. However, the control of risk covers a range of different strategies, including prevention, mitigation and, at worst, failure recovery. Of course, individual attitudes to risk are complex and subject to a wide variety of biases and influences. For instance, John Ettlie, an authority on managing technological innovation references what he describes as a little known but interesting empirical study into risk aversion amongst managers.2 Figure 10.5 shows a simplified representation of the results, with larger scores on the vertical axis representing greater risk aversion. It was found that older managers would be more risk averse (line A). However, closer analysis of the data revealed the more interesting result (line B). Risk aversion decreased sharply until about 35 but then leveled off until about 50 when risk aversion set in again. The study3 offers interesting insight into the relationships that exist between risk cognition and the individual. In fact, many studies have demonstrated that people are generally very poor at making risk-related judgements. Consider the success of state and national lotteries. In nearly every case, the chances of winning are extraordinarily low, and the costs of playing sufficiently significant, to make the financial value of the investment entirely negative. If we broaden the analysis further, then participation can begin to seem foolhardy. For example, if players have to drive their car in order to purchase a ticket, they may be more likely to be killed or seriously injured than they are to win. Individual perceptions, or ‘subjective’ judgements, will probably not coincide with an expert, or ‘objective’, view. 2 Ettlie, J. (1998) Managing Technological Innovation, Free Press, New York. 3 Vroom, V.H. and B. Pahl (1971) ‘The relationship between age and risk taking among managers’, Journal of Applied Psychology, Volume 55, No. 5, pp. 399–405. 370 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Commentary on example – Planning for recovery As a postscript to this story, in July 2007, confectionery giant Cadbury was fined £1m for food and hygiene offences over the salmonella outbreak at the firm’s plant in Herefordshire that made more than 40 people ill, with three requiring hospital treatment. In addition, the firm was ordered to pay an additional £152,000 in costs. The outbreak led to the recall of more than a million bars in the UK. Birmingham Crown Court was told the outbreak was caused by a leaking pipe at the Marlbrook factory, where salmonella was found in some of the firm's products between January and March 2006 and Cadbury’s recalled many of its products on 23 June. At the hearing, the court heard how Cadbury changed its quality-testing systems, allowing salmonella to enter its chocolate bars, to save money. However, the judge said he did not believe the firm had made the changes in a deliberate cost-cutting attempt. Rather, he said, 'I regard this as a serious case of negligence. It therefore needs to be marked as such to emphasize the responsibility and care which the law requires of a company in Cadbury's position.' The Company admitted nine charges brought by Herefordshire and Birmingham councils. A total of 42 people fell ill. The solicitor representing some of the people affected by the contaminated chocolate, said: 'Our clients are relieved that Cadbury have pleaded guilty to the charges brought against them, and in doing so accept their responsibility to the public.' ‘The £1m fine sends a clear message that companies who have a great deal of responsibility for protecting public health cannot afford to ignore a potentially dangerous situation and 371 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual cannot take a risk with the public's health.’ A spokesman for Cadbury apologised and offered the company’s ‘sincere regrets’ to the people who were taken ill. ‘Quality has always been at the heart of our business, but the process we followed in the UK in this instance has been shown to be unacceptable. We have apologized for this and do so again today. In particular, we offer our sincere regrets and apologies to anyone who was made ill as a result of this failure. We have spent over £20m in changing our procedures to prevent this ever happening again.’ Risk, learning and methodology Not infrequently large companies are capable of accumulating, sometimes significant, experience concerning the management of implementation. Not only is there a large selection of widely applicable methodologies in their ‘implementation toolbox’ but, equally important, some organisations may have become expert in identifying, deploying and constantly improving the appropriate methodologies for all types of project. One study, based on a large multinational group, summarised key study guides from the many hundreds of implementation projects undertaken by the group. It was seen as important to do this because truly effective implementation requires not only that the business improves its current operational processes but also that it improves the implementation process itself. Of course, a commitment to implementation is nothing new. Many large groups have, for years, run many local operations strategy implementation projects. But whilst there may be a common approach, the ‘learning’ from each project is not always systematically captured, reviewed or shared. Operations strategy implementation is seen as being a local activity. Implementations, even if significant, are not always used as a source of valuable learning that is capable of being spread globally. Good implementation methodologies have some common characteristics. • They must be (financially) realistic and deal with the problems as they are. The sheer scale and cost of some implementations means that it is critical that the project tracks specific benefits and ensure that operational targets were accurately included in the Profit & Loss Accounts for future business plans. • They should be generic, applicable across a wide range of activity and able to guide action. For example, the group defined a common approach for measuring capacity utilisation. This process identified that only two-thirds of the group’s industrial assets were being effectively utilised. Emerging out of this analysis, generic opportunities for implementation were identified in areas such as: focused investments, identifying site locations, standardisation and harmonisation of products as a means to focus the product mix and achieve economies of scale, more effective technology deployment and so on. • They should be adaptable and capable of being developed and modified to fit specific circumstances. An operations strategy implementation planning methodology should be capable of being developed and institutionalised in other parts of the group. • They should be educational. In addition to helping to solve particular problems, they should also contribute to the implementation team’s own understanding and capabilities. 372 © Nigel Slack and Michael Lewis 2012 Nigel Slack and Michael Lewis, Operations Strategy, 3rd Edition, Instructor’s Manual Stakeholders Chapter 10 finishes with a reference to monitoring and control from a stakeholder perspective. While this is a significant and useful angle on implementation in general, it is important to recognise that the stakeholder perspective is not without its critics. It is not that the model is unattractive. The success of the stakeholder model in management literature and business practice is mainly because of its innate simplicity, clarity and ethical attractiveness. Yet it has also attracted criticism. Critics cite the lack of clarity, abstraction and ambiguity of stakeholder theory. But a more fundamental criticism of stakeholder theory is that it threatens conventional business objectives. Or, put another way, the only end of a business is to balance the interests of stakeholders no matter how impractical this may be. The stakeholder theory implies the full inclusion of everyone who has a legitimate interest in the firm. Yet for most firms this is a very large number. At the very least, there would need to be some way of both delineating and prioritising stakeholders. More seriously, critics of stakeholder theory have argued that it fundamentally under represents the moral (and often legal) rights of stockholders. Nevertheless, even accepting some of the objections to stakeholder theory, as an organisational mechanism, incorporating the interests of a relatively wide cluster of individuals and groups who have an interest in the outcome of an implementation, seems broadly sensible. As the chapter put it, notwithstanding any ethical imperative to include as many stakeholders as possible in an implementation, it also can prevent problems later in the implementation. 373 © Nigel Slack and Michael Lewis 2012
