H&M: A GLOBAL FASHION COMPANY From its humble beginnings in 1947 as a single shop in Sweden, H&M is now one of the biggest names in the retail fashion industry. H&M employs over 130,000 people, both in Sweden and in its nearly 4,000 stores, which are in over 60 countries, right the way across the globe, including most countries in Europe, as well as many in the Middle East, Africa, Asia and the Americas. It plans to open further stores (it has a target of increasing the number of stores by 10–15 per cent each year), as well as expanding its online sales operations by rolling out its digital presence to an increasing number of countries. H&M’s digital ambition means setting up not only a dedicated website to serve each new country, but also the physical systems that can ensure goods ordered on it will be delivered to customers in that country. The most visible part of H&M’s operations is its stores. The company says it wants these to provide an ‘inviting, inspiring and exciting experience’ to shoppers. While every store is unique, any is immediately recognizable as H&M from its signage, window displays and internal layouts. All stores seek to place the clothes centre stage through the use of internal displays that aim to provide styling tips and inspiration. H&M’s online stores try to emulate this experience in the virtual world, while providing additional accessibility for customers who can’t easily get to H&M physical stores, and enhanced levels of service by enabling customers to view and order a much wider range of merchandise (and in many more sizes) than would be possible in any physical store. However, the stores are only the end point of a much longer supply process. This starts with design. All of H&M’s garments are designed in Stockholm by its in-house team of clothing designers, patternmakers and print designers. They aim to provide something for men, women, teenagers and children, whatever their taste or style. In contrast to the design process, H&M does not produce any of its garments in-house. Rather, it draws on a network of over 1,900 factories owned by as many as 900 independent suppliers, which are based in countries such as China, Turkey, Bangladesh, Cambodia and India. H&M views its suppliers as long-term strategic partners who manufacture its products, including being responsible for sourcing the necessary fabrics (mainly cotton) and the other components needed. H&M’s logistics and distribution operation must then ensure that the right goods end up in the right quantity as required by each store. Factory shipments are transported, mostly by sea and rail, to H&M’s logistics centres, which are strategically located in the geographic vicinity of its stores in each region. Stores do not hold backup stocks, and so must replenish as required from the distribution centres. In 2013, H&M launched its Garment Collecting Initiative, which enables customers to hand in clothes that they no longer want for reuse or recycling. This is aimed at creating a closed loop in textiles, so that nothing ever goes to waste. The first H&M garments containing materials from the Garment Collecting Initiative were launched in 2014 – denim garments that contained 20 per cent recycled cotton.

POINTS TO PONDER AS YOU READ THIS CHAPTER: »Notice the different types of operations occurring throughout H&M’s business (e.g. design, production, logistics and distribution, retail). Some of these are manufacturing operations, and some are service operations. Each uses different types of resources to produce different kinds of outputs. »Notice how H&M’s shops rely on a complex interconnected global supply network to ensure that goods are available to customers. »Think about what led H&M to operate on such a vast global scale and about the challenges posed in managing all of these operations, both individually and collectively. INTRODUCTION Operations management is crucial to the lives of all of us. That is because operations management is responsible for the creation and delivery of all the products and services that we need for our daily lives, including all the food that we eat, the clothes that we wear, the transport we use, the health services that we receive, and so on. All of these were brought to you courtesy of operations management. Unless you live as a self-sufficient hermit in an isolated cave, there is unlikely to be any aspect of your life that is not entirely dependent upon operations management. That is because nearly every physical product or intangible service that you consume or use is created and delivered by some kind of business organization. And the operations function is the part of that organization that is responsible for producing the goods and services it supplies to its customers. All organizations have operations functions, although they often go under other names. These often reflect the specific activities that they carry out, for example catering, distribution or nursing. There is a misconception that operations management is only concerned with manufacturing activities. Although many of the concepts on which the academic study of operations management is based do have their origins in the manufacturing industries, many are equally applicable to services. Conversely, recent advances in the study of service operations have yielded valuable insights into the management of manufacturing operations. The distinction between manufacturing and services is in many respects artificial and increasingly irrelevant because most products have some element of service accompanying them. For example, when you buy a new computer (an entirely physical product), you assume that you are also buying access to aftersales services, such as operating guidance, software updates and repairs. Equally, many services have a tangible product as an integral part of what is delivered to the customer. For example, as a passenger on an airline (an entirely intangible service), your flight, especially if it is long-haul, is usually accompanied by the provision of on-board food and drink (an entirely physical product). Operations management is concerned with the management of the resources and processes required by an organization to produce goods or services for customers. The operations function is that part of the organization that has the responsibility for operations management. Operations management is the most exciting of the business disciplines. Marketing is concerned with identifying and creating customer needs. Finance is concerned with ensuring that the organization has the necessary financial resources to conduct its business. Similarly, human resource management is concerned with ensuring that the organization has the necessary human resources it needs. Operations management is concerned with the management of the resources and processes required by an organization to produce goods or services for customers. The operations function can best be thought of as the ‘doing’ part of the organization. It is where the action is. Operations management is critical to the success or failure of an organization. Any organization exists to deliver a service of some kind and/or to make a product. If its operations management fails, then the organization will fail. The operations function is responsible for the majority of the organization’s costs, assets and people, typically accounting for 60–70 per cent of each (Hill, 2005). Operations management is important because of its direct impact on costs. No organization can be successful unless its operations are managed cost-effectively. However, operations management is also important because of its impact on non-cost factors such as the quality, availability, timeliness and reliability of the goods and services provided by the organization. All customers judge the value of what they receive by some combination of these factors. No organization will be successful for long unless it provides goods and services in a way that satisfies its customers by providing them with the value they seek. The context in which operations management is practised has been changing in recent years. Until comparatively recently, most production processes in most organizations were organized and took place within national boundaries. Although manufacturers may have imported the raw materials they needed, most produced goods primarily, if not exclusively, for local consumption. Similarly, it was rare to find any service that was not produced and consumed locally. It was unusual to find production processes that crossed national boundaries. This has been changing for some time as the forces of globalization have led to the internationalization of operations. For many organizations, the last decade has seen an acceleration of the trend towards the fragmentation of production processes. Today, many operations processes cross international boundaries in ways that were not previously possible. For example, the cup of coffee that you buy from your local Starbucks coffee outlet may depend on operations taking place in as many as 19 different countries. The coffee beans may come from plantations in countries as diverse as Kenya, Saudi Arabia, Indonesia and Colombia. The beans would have then been sent to one of the company’s roasting, manufacturing and packaging plants in the US. The paper for the cups and napkins could have been produced from forests in Sweden. The sugar could have come from Brazil. The milk could have come from Australia. All the required final products would then have to have been transported to your local Starbucks, one of 22,000 outlets worldwide in over 60 countries. Neither is Starbucks exceptional. Improvements in transport systems have made the movement of materials much easier and cheaper. New centres of manufacturing have emerged in newly industrialized economies (NIEs), such as China, India, Brazil and Mexico, that offer resources, particularly labour, at a fraction of the cost available in traditional manufacturing locations. Workers, especially those with the most sought-after expertise, can move between countries with much greater speed and ease than was the case in the past. Today’s financial systems and markets enable virtually unlimited amounts of capital to be transferred across the world instantaneously. And, perhaps most importantly, unlimited quantities of information, including new ideas and innovations, can be communicated and shared almost instantaneously across the world thanks to the Internet. These factors have all become increasingly important not only to manufacturing, but also in many services, and particularly in information- and knowledge-based contexts. Internationalization is the process of expanding business operations across international boundaries. At first, this might only involve exporting or importing goods and/or services. But it might go on to involve the establishment of production facilities in other countries, as well as facilities to support sales, research and development, and other activities in foreign countries. A newly industrialized economy (NIE), sometimes also termed a newly industrialized country (NIC), is a country that has undergone a considerable level of industrialization in the recent past, switching its primary economic activity from agriculture to manufacturing, and possibly services. NIEs are not quite yet at the status of the industrialized nations of the West, but are more advanced than the countries of the Third World. The transformation process is the system by which inputs of resources (e.g. people, equipment, materials, energy, information) are converted into outputs of goods and services. THE TRANSFORMATION MODEL Any operation can be depicted as a transformation process that converts inputs into outputs of goods and services (see Figure 1.1). For the inputs, it is useful to distinguish between: »The primary inputs that are themselves transformed to become part of the output of the operation. These are sometimes referred to as ‘transformed resources’ (Slack et al., 2013). Primary inputs can be materials and/or information and/or customers. »The resources necessary to carry out the transformation, but which do not themselves form part of the output. These are sometimes referred to as ‘transforming resources’ (Slack et al., 2013). Figure 1.1 The input-output transformation model for operations Source: adapted from Operations Management, 7th edition, by Nigel Slack, Alistair Brandon-Jones and Robert Johnston, Pearson Education Limited. © Nigel Slack, Stuart Chambers, Christine Harland, Alan Harrison, Robert Johnston 1995, 1998. © Nigel Slack, Stuart Chambers, Robert Johnston 2001, 2004, 2007, 2010. © Nigel Slack, Alistair Brandon-Jones, Robert Johnston 2013. These can typically be classified as: »Facilities: These are the resources that are necessary to undertake the operation, but which are not used up in the operation. Typically, these include the land, buildings, equipment and vehicles used by the organization to perform the operation. These resources are usually intended to be used over several years. Consequently, they are normally designated as fixed assets by accountants, and their value appears in the fixed assets column of the balance sheet. »Consumables: These are the resources that are used up as part of the operation. Examples include the energy necessary to power buildings, plant and machinery, and the materials necessary to maintain, repair and operate them (often referred to as MRO supplies). »People: The human resources necessary to undertake the operation. These will usually include the staff of the organization. However, employees of other organizations might also be involved in the transformation process, for example those belonging to the suppliers or subcontractors of the organization undertaking the operation. The transformation model sees operations management as those activities that are concerned with how these resources are managed in order to produce the required outputs of goods and services. DIFFERENT TYPES OF OPERATIONS Operations can be classified into three different types depending upon which type of primary input is principally being transformed in the operation: »Material-processing operations are those in which materials are transformed either from one form to another, and/or from one place to another. Manufacturing operations in which raw materials and components are transformed into finished products fall into this category (e.g. manufacturing a car or producing a garment). Other material-processing operations include mining, and the transport, storage and distribution of goods in warehousing and retailing operations. »Information-processing operations are those in which information is transformed from one form to another and/or from one place to another. There are many examples of information processing, including accountancy, banking, financial services, telecommunications and research of all kinds. Nowadays, it is difficult to think of information-processing operations that do not involve the use of computers. »Customer-processing operations, in which the customer is transformed by the operation. There are many examples of this type of operation, including medical services (e.g. hospitals) in which sick people are, hopefully, made well, education, where people are transformed by gaining additional knowledge or skills, and entertainment, where people are transformed by the emotional benefit gained from the event. While one of these types of processing often predominates in any particular operation, many operations also typically involve two or even all three types. For example, a restaurant processes both materials (food) and customers; a book publisher processes both information (the text for the book) and materials (the paper, ink, etc.); and an airline processes customers (passengers) and materials (their baggage). TOYOTA: THE WORLD’S NUMBER ONE With global sales now at 10 million vehicles per annum and climbing, Toyota finds itself as the world’s leading auto manufacturer. US giant General Motors, which had previously held this title for 74 years, was dethroned in 2006, and the Japanese automaker has not looked back since. In a financial climate in which most of the top automakers have experienced declines both in sales and profits, Toyota stands out for its burgeoning financial returns, which are not restricted to the established US market, following investment in China’s developing market. Environmental and technological advancement, in the form of its part-electric, part-petrol hybrid models, also creates healthy demand. Toyota’s Lexus subsidiary also taps into the US luxury market, propelled in 2016 through its RX crossover model, which exceeded sales forecasts. Despite the fact that it dates back to 1937, Toyota rose from relative obscurity in the 1950s through Taiichi Ohno’s development of the Toyota Production System (TPS). Based on Japanese principles such as jidoka (referring to human automation), muda (elimination of waste) and kaizen (continuous improvement), TPS enables greater cohesion within the manufacturing process, particularly with regard to team- and management-based tasks. In an industry that is so dependent on intricate supplier collaboration, it has been claimed that TPS helps to achieve this end, insofar as it minimizes defects. The eradication of such design flaws also allows newly created products to reach the customer in a shorter time than can be achieved by other companies, and with a greater level of quality control. Getty Images/Hero Images This approach to production has been researched and emulated by a number of international carmakers and is now considered the industry gold standard, while also finding traction within other sectors. Now articulated as ‘lean’ production, numerous service environments have also incorporated this approach. One such surprising application of TPS methodology can be found within the field of healthcare, in which the traditional focus upon meeting objectives is replaced with the prioritization of processes. Each role within the organization is defined in terms of key competencies, and, as these are met, patient needs are satisfied with greater consistency. TPS has been regarded as the secret to Toyota’s success, implementing increased flexibility and productivity while eradicating many of the production errors that plague other car manufacturers. As a result, the company does not need to resort to competitor-minded discounts in order to satisfy a customer base that is happy to pay for quality. As Toyota continues to outperform its rivals for a fourth consecutive year, it now contemplates consolidating its position through business partnerships with manufacturers such as Daihatsu and Suzuki. And yet, at the heart of this increasingly outward-looking company remain the streamlining qualities facilitated through the TPS, which acts as an integral foundation for such growth.

QUESTIONS 1.What type of operations are most important to Toyota? 2.To what extent does Toyota’s success depend on its operations? SERVICE OPERATIONS Operations can be classified more simply in terms of their outputs, as either goods or services. The factors that distinguish them are: »Tangibility: Goods are physical products that can be touched, seen, tasted or smelled. As physical entities, goods can be stored and transported. The ownership of goods can be transferred from the supplier to the customer. Services, on the other hand, are intangible, and therefore unlikely to possess any of these properties. »Simultaneity: Services are distinguishable from goods in that their production and consumption usually takes place simultaneously. As such, it is usually not possible to store a service that has just been produced for consumption at some time in the future. Normally, customers have to be present to receive the service when it is produced. On the other hand, goods can usually be stored ready for future consumption by a customer. »Customer contact: Because of their intangibility and simultaneity, services normally require some degree of contact with the customer, although the degree of that contact can vary. Similarly, some services are much more labour-intensive than others, and might involve the customer coming into contact with large numbers of employees of the service delivery organization, such as in a visit to a hospital or staying in a hotel. »Quality: Because of the nature of the output of a service operation, it is much more difficult to define and measure the quality of a service. The quality of a product can be defined and measured in terms of its functionality (i.e. its fitness for the purpose for which it is intended). The quality of a service, on the other hand, can often only be judged by its recipient. Service quality is dependent on the perception of a customer. Such perceptions may vary between one customer and another, and between the customer and the service deliverer. As such, service quality often depends upon the psychological state of a customer at the time of consumption. Indeed, some services are intended to change a customer’s psychological state. Services are the intangible outputs from an operation. It is possible to think of examples that equate to the extremes of pure goods (coal mining) and pure services (psychotherapy). However, a closer consideration of the outputs of most operations reveals that it is rare to find such extremes. Usually, there are elements of service in most goods-producing operations. For example, even extractors of commodity goods such as coal or oil typically provide their customers with information about their chemical composition or offer technical advice on their use. Similarly, even producers of a highly customized service such as management consultancy will usually produce some tangible output, such as a written report of some kind. It is usually more helpful to think of the outputs of operations as being located somewhere on a continuum between pure services and pure goods (see Figure 1.2). Many service operations are different from those in manufacturing, in that they usually require the operation to have some degree of contact with the customer. Organizations that treat their customers in the same way that they treat the inanimate objects that are materials are neither likely to retain existing customers nor attract new ones. The study of service operations has led to the development of some useful concepts in addition to those that have emerged from the study of manufacturing. One such concept is that of the difference between the front office and the back office. The area in which contact with customers occurs is termed the front office. This primarily involves customer-processing operations. The area where there is normally no contact with customers is termed the back office. This may involve information- and/or material-processing operations (see Figure 1.3). The transforming resources required in the front office are likely to be significantly different than those needed in the back office. In particular, operations in the front office need to revolve around the customer. The people that work in the front office are likely to require quite different skills than those in the back office. Front office staff need high levels of interpersonal skills if they are to interact successfully with customers. The physical resources used in the front office, buildings, machinery and equipment may also need to be quite different from those in the back office. Indeed, the front and back offices may well be physically located in quite different places. However, the relationship and interaction between front and back office operations is often a key part of the management of operations. The front office is the area of an operation in which contact with customers normally takes place. The back office is the area of an operation in which there is normally no contact with customers.

WHEN THINGS GO WRONG HONG KONG DISNEYLAND: THINGS CAN ONLY GET BETTER However, after opening its gates in September 2005, it became clear that there were some significant problems in its operations. Despite the fact that, at 30,000 visitors, the park had the lowest capacity of all Disneyland parks, this was revealed to be an unmanageable number when 29,000 locals converged on Hong Kong Disneyland on the day prior to its grand opening. Unfortunately, these prospective visitors fell victim to the irony of 45-minute waits for fast food and ride queues of up to two hours, a fact not wasted on local media, who were quick to comment on the park’s chaotic management. The day after, on the park’s official opening, a seemingly manageable 16,000 visitors gained entry, with approximately one-third comprising of mainland Chinese park-goers, and it was this group that locals blamed for, among other things, smoking in non-designated areas, GRAPHEAST Hong Kong Disneyland’s final construction on the reclaimed land of Lantau Island in 2005 marked the culmination of a $1.8 billion joint partnership with the Hong Kong government. Targeting not only the flourishing wealth found among China’s citizens, the park also attracted a significant number of visitors from surrounding South East Asia. To this end, designers wished to incorporate elements of Chinese tradition and culture through the use of feng shui in its stylistic composition. Reportedly, such design choices even dictated the rotation of the front gate by 12 degrees, which a feng shui specialist assured would lead to greater prosperity in the park’s future. Clearly, park management were leaving nothing to chance. queue-jumping, public urination and spitting. Park staff also bore the brunt of customer blame on the basis that such visitors should not have been admitted entry, and, even on the opening day itself, it was reported that staff were discourteous and unhelpful. For Hong Kong Disneyland, the problems did not end on its opening day, as approximately 50 rides experienced technical difficulties, leading to the employment of safety protection systems. As a result of such shutdowns, there were six instances of visitor sickness and minor injuries sustained. In addition, worker complaints included commuting, rota and management communication problems. Marking perhaps the nadir of the park’s woes, during Chinese New Year, in February 2006, a ticketing malfunction led to entrance having to be refused to new visitors who had valid tickets, because the park was already full to capacity. As a consequence of the over-ticketing fiasco, some prospective park-goers stormed their way in, and the sight of a child being passed over spiked gates to his openarmed parents who waited inside the park provided local television with a poignant visual example of the park’s inadequate planning. Since then, further complaints have been made regarding the park’s lack of size, attractions and competent staff. Disney enthusiasts also make unfavourable comparisons between Hong Kong’s 22 major attractions, compared with Tokyo’s 45, and Paris and Florida’s 44 and 65, respectively. This considered, Hong Kong bears the highest cost per ride of all its equivalent parks. As previously alluded to, tensions between Hong Kong locals and mainland Chinese visitors can quickly escalate, and such visitors lamented the park’s lack of Mandarin instruction, which is the dominant language of China. This problem arises from the fact that Cantonese is the language of southern China, including Hong Kong, but it is unintelligible to a purely Mandarin speaker, which remains the language of the Chinese government. One implication of this linguistic impasse was found in the live shows, in which the characters spoke no Mandarin and the props and voice-overs on all but one of the rides were in English. The resort’s management acknowledged such developmental difficulties, vowing that such problems remained common to all new ventures and that improvements could be made. At the peak of the park’s problems in 2006, even the Hong Kong government was forced to call on Disneyland to make improvements both to entry procedures and ticketing. Since this intervention, park pricing, opening times and ticket policy have been altered in order to spread admittance throughout the week and ease the strain that is placed on the park infrastructure. Datespecific tickets are now used to ease congestion during busy periods, and particularly Chinese holidays. Better staff training now ensures that Cantonese, English and Mandarin can be spoken and, along with multilingual guide maps, these help to ensure that customer satisfaction is achieved across the broad range of visitor nationalities. A new induction programme, aimed at quickly introducing mainland tourists who are unfamiliar with the Disney brand, has also been introduced. Clearly, without the previous childhood exposure to such characters, a visit to the park would represent an extremely disorientating, and perhaps even alienating, experience, so Disney has worked to minimize this possibility, and, in doing so, maximize brand exposure. To this end, the park has developed a pre-show movie that can be shown to its visitors when they initially get to the park. Upon entry, visitors are taken to an area for approximately 15 minutes, where they are regaled with the cornucopia of Disney characters and their associated attractions. This allows Chinese tourists to learn about Disney’s history while rendering Hong Kong Disneyland as increasingly attractive to Chinese travel agents. Finally, in 2012, the park turned its first profit, following six years of continual losses. Attraction investment has facilitated consistent visitor figures, and the park finds itself in the prestigious group of the world’s top 15 most visited theme parks. And yet, significant threats are posed by a struggling Chinese economy and the rival Disneyland Shanghai park, which is three times its size. However, as Hong Kong Disneyland has shown, the Shanghai park must continue to closely monitor the 10,000 employees who worked on its opening day in order to make continual improvements to customer experience.

QUESTIONS 1.What were the main problems experienced by Hong Kong Disneyland in its ‘front office’ operations? 2.What seem to be the main causes of these problems? 3.What more could have been done to overcome these problems? TAKING IT FURTHER Much of the academic discipline of operations management is underpinned by the ideas of ‘systems theory ’, also often referred to as ‘systems thinking’. Investigate the ideas of systems theory and systems thinking to gain a better understanding of what they mean when applied to the management of business operations. In particular, note the difference between an open and closed system. Consider the extent to which operations systems in organizations are open or closed, and what this means for their management. THE CHANGING NATURE OF OPERATIONS MANAGEMENT In recent years, the way both academics and practitioners think about the subject of operations management has been changing. This has been reflected in the content of operations management as an academic discipline. The most notable of these are: A supply network is the set of interconnected relationships between all the parties that supply inputs to, and receive outputs from, an operation (including the suppliers’ suppliers and their suppliers, etc., and the customers’ customers and their customers, etc.). Moving beyond the factory The roots of operations management lie in manufacturing, and for many years the subject focused almost exclusively on what went on within the confines of the factory. This had the benefit of enabling the development of very specific and detailed expertise about the production of physical goods. In particular, it enabled very many mathematically based tools and techniques to be developed that could help in vitally important factory tasks such as production planning and scheduling (see Chapter 8), inventory control (see Chapter 9) and quality control (see Chapter 11). However, restricting operations management to the consideration of factory-based activities alone is limiting because the performance of operations is affected by what goes on outside of the factory as much as by what goes on within it. Most operations take place within a supply network, which comprises all the suppliers to the operation (and all their suppliers and their suppliers) and the customers of the operation (and all their customers and their customers). The performance of an organization’s operations and the extent to which it can satisfy customers depends significantly on the performance of suppliers and others in its supply network (see Chapter 7). Thus, supply network relations are increasingly recognized as being vitally important in operations management. Within the organization, interactions with the other functional areas of business also have a significant impact on the performance of operations. For example, if the marketing department’s advertising campaign raises customer expectations in ways that make it difficult for the operations department to meet, there will be an increased likelihood of customer dissatisfaction. Similarly, the operations function cannot operate effectively unless the finance department is able to arrange adequate funding and the human resource management department is able to attract and retain workers with the right skills and attitude (see Chapter 12). As will be discussed in Chapter 3, functional-level strategies (for operations, marketing, finance, human resource management, etc.) need to be consistent with one another and with the organization’s business strategy if they are to contribute to achieving a competitive advantage. In the past (and perhaps too often today), many organizations considered the prime role of operations as being concerned with cost-cutting and efficiency gains in order to achieve the lowest possible operating costs. Viewing operations in this way severely constrains its strategic role. As not all organizations compete on the basis of price alone, operations can only be used strategically as a competitive weapon if its performance objectives are aligned with those of the organization’s business strategy. These may well require operations to meet customer requirements in other aspects of performance (e.g. quality, flexibility, dependability and speed), and not just cost alone (see Chapter 2). The increased importance of the supply network For many years, there has been a trend for organizations to obtain a greater proportion of their inputs from external suppliers, buying them externally rather than producing them internally. In particular, many organizations have been making greater use of suppliers based in other countries, as they can often offer lower prices. Such international sourcing means that more organizations become part of international supply networks. The greater use of offshoring in the sourcing of suppliers typically causes the physical lengthening of the supply chain and increases its vulnerability to disruption. The management of international supply is both more important and more complex than when purchasing from local suppliers. It is difficult to envisage any reduction in the internationalization of supply networks, so this aspect of operations management seems set to remain important for some time to come. The growing importance of services It is invariably the case that as a country develops economically, the proportion of its national economic output arising from services increases. Similarly, the proportion of its citizens in paid employment in service industries also tends to increase. Thus, the service sectors of most national economies have continued to grow in importance. Even China, where GDP has rocketed in recent years on the back of its hosting of offshored manufacturing operations from the West, has now reached the point where the growth in its service industries is outstripping that of its manufacturing industries. In most countries today, services normally account for the majority of the value of a country’s output, its gross domestic product (GDP), as illustrated in Table 1.1. Offshoring involves moving certain operations to another country. This could be done either by relocating the affected operations to the organization’s own facilities in another country, or by outsourcing the operations to a foreign supplier. The motivation for this is often, but not exclusively, cost saving. Gross domestic product (GDP) is a measure of the size of a country’s economy. It is defined as the market value of all final goods and services produced within the country. As services have grown in importance in most of the world’s major economies, service operations management has emerged as an increasingly important field of study. It would be odd indeed if operations management as a subject were to ignore this vitally important sector of most national economies. It would do a grave disservice to those working in the service economy and sideline the subject of operations management (and those who teach it) within the business school curriculum. Operations management academics have therefore been giving service operations much more attention in recent years. They have done this in two ways. First, by seeking to apply concepts and techniques developed in manufacturing contexts to service environments. Examples of this include the application of lean thinking (see Chapter 10) to services such as hospitals and statistical quality control techniques (see Chapter 11) to monitor performance in sectors such as hospitality and air travel through the use of customer feedback questionnaires. Second, by developing new concepts and techniques that take account of the specific characteristics of service operations. Examples of this include the quality gaps model, described in Chapter 11, and queue management techniques, discussed in Chapter 8. Both of these trends seem set to continue as services grow in economic importance. Therefore, it is likely that greater consideration will continue to be given to service issues within the operations management discipline for some time to come. Some important associated developments in service operations management include: Table 1.1 Percentage GDP (2012) by sector for selected countries Source: The World Bank: World Development Indicators: Table 4.2 Structure of output, available at: http://wdi.worldbank.org/table/4.2(accessed 26 February 2015). To view the terms of use, please visit www.worldbank.org/terms-of-use-datasets Mass customization is the use of a single process to produce a wide variety of products (or services). It aims to realize unit cost reductions through economies of scope in the same way that mass manufacturing aims to achieve economies of scale. Economies of scale are reductions in unit cost of output due to increasing production volumes. Unit cost savings are achieved by spreading the fixed costs of production over an increased volume and from the increased efficiency available from the division of labour and from using large-scale machinery. Servitization is the process through which manufacturers provide an accompanying service or services for their traditional product offering in order to add additional value for their customers when they are using that product. The internationalization of service operations In the past, most services had a high degree of simultaneity (i.e. their outputs were consumed at the point of production). This made them difficult, if not impossible, to trade between countries, as providers needed to be physically present at the point of consumption. However, Internet technologies are now changing this, reducing or removing the need for service provider and consumer to be in physical contact. For example, some medical diagnosis and even treatment can now be conducted via telemedicine techniques. Similarly, many tangible aspects of services can be digitized (e.g. the written word, music, moving images), making it possible to deliver them electronically from a distance. This is prompting two trends. First, operations that were previously thought of as front office, such as the provision of most aspects of personal financial banking services, because of the requirement for both customer and service provider to be in the same location at the same time, can now be transferred to the back office. It is the information that travels rather than the people. Second, there is now a reduced need for front office and back office operations to be co-located. This means that there are ongoing opportunities to locate back office operations in other areas, often in offshore locations, where there is an abundance of either low-cost or high-skilled workers. Mass customization in services The use of digital technologies has opened the way to mass customization in ways that were not previously possible, making it possible to tailor products and services to individual customer requirements, while at the same time lowering costs due to economies of scale in production. A good example of this is recorded music. When this had to be transmitted via a physical device such as a CD, then the list of tracks included was predetermined by the supplier. Only the mass production of identical products could enable each CD to be produced at a low enough cost for it to be offered at an affordable price to customers. Now that music can be digitally downloaded from Internet sites or heard via online streaming services, customers can select whatever pieces of music they want, in effect creating their own customized CDs. Furthermore, they can do so at as low or perhaps a lower price per track than would have been on the CD. Servitization to differentiate products Despite moving their manufacturing operations to lower labour cost offshore locations, many suppliers of physical goods still find it difficult to achieve satisfactory levels of profits in highly competitive markets. More and more are therefore looking to use the provision of accompanying services as the means of differentiating their offerings from competitors and customizing their offering to meet specific customer needs. An example of such servitization is provided by aero engine maker Rolls-Royce. They offer customers a ‘power by the hour’ package of aero engine performance for an aircraft that takes care of all of the necessary support, including maintenance, rather than merely selling engines and providing a separate maintenance service. This means that their customers, the airlines, in effect, only pay for their engines when they are working. THE INTERNATIONAL CONTEXT FOR OPERATIONS MANAGEMENT It is generally accepted that over the last 30 years or so, a number of powerful factors have combined to produce the phenomenon that has become known as globalization. This has led to the increasing integration of economic activity around the world, evidenced in the growth in international trade and the increasing interdependence of national economies. Many commentators also emphasize the increase in cross-border social, cultural and technological exchange as essential concomitant elements of globalization. Globalization has proved to be a contentious issue. Its critics point to the dominance of Westernized free-market economics, the growing power and influence of multinational enterprises (MNEs), and the detrimental impact on less developed countries (LDCs) and the natural environment. This book will studiously avoid considering the rights and wrongs of globalization. There are many other forums in which to do so. Our concern is rather to understand the phenomenon and its resultant impact on the internationalization of operations management. The factors driving globalization can be classified under four broad headings: technological, political, sociocultural and economic. These are now discussed in turn below. Technological The digital technology revolution, driven by ever-increasing processing power of computers and the near ubiquitous presence of the Internet, continues apparently unabated. Many analysts argue that these information and communication technologies (ICTs) and their supporting infrastructure of cables and satellites have created a new techno-economic paradigm that is underpinning a fifth Kondratiev long wave1 of economic growth (Dicken, 2015). There can be no doubting the growing importance of the Internet for businesses and individuals. In advanced economies, all but the smallest firms make at least some use of the Internet in their businesses. In the retail sector, use of the Internet is now mature, with, for example, nearly 70 per cent of Swedes, 65 per cent of British and 57 per cent of Americans undertaking some of their shopping online in 2015, according to Digital Strategy Consulting (2015). The Internet now has over 3 billion users, and 40 per cent of the world’s population have an Internet connection (Internet Live Stats, 2015). However, Internet penetration rates vary widely. Extreme examples are the case of Eritrea, where less than 1 per cent of the population have Internet access, and Qatar, where 97 per cent have Internet access. Globalization refers to the increasing integration of economic activity around the world, evidenced in the growth in international trade and the increasing interdependence of national economies. An increase in cross-border social, cultural and technological exchange is also a feature of globalization. A multinational enterprise (MNE), or sometimes also termed a multinational company (MNC), is a business organisation that has operations in a number of different countries. A less developed country (LDC) is one whose economy is underdeveloped, relying mostly on agriculture (and possibly extractive industries), and whose population has a low standard of living. One of the main benefits of the Internet is that it facilitates cheap and easy direct personal contact, irrespective of distance. Whether we have yet come to a point where the Internet has led to the death of distance (as predicted by Cairncross, 1997) is probably questionable. But the Internet’s ability to reduce the effects of distance can be significant. The use of email, instant messaging (Facebook, Twitter, WhatsApp, etc.) and other forms of digital communications enables individuals and organizations to communicate with one another almost anywhere on the planet. Almost limitless quantities of data can be transferred within seconds. Low-cost video conferencing services such as Skype and FaceTime can enhance, if not completely replace, the more impersonal aspects of communicating via the written word on a computer, tablet or smartphone screen. Within a few short years, online trading between businesses (B2B) and between businesses and consumers (B2C) has become commonplace. Traditional business supply chains have been disrupted, with both disintermediation and re-intermediation in evidence. In some cases, suppliers have chosen to bypass the traditional distributors of their industry and trade directly with customers (e.g. Amazon, Dell). In other cases, new intermediaries have emerged and reconfigured supply (e.g. Travelocity for travel and Amazon for shopping). If products can be digitized (e.g. music, movies, the written word), they can be delivered directly to consumers via the Internet, thereby removing the need for the traditional distribution channels. The Internet can facilitate access to new customers at a fraction of the cost of more traditional means. For example, online banking makes it possible to offer customers the ability to undertake almost all traditional transactions without the need for traditional banking halls. B2B (i.e. business to business) refers to a transaction that takes place between one business organization and another. B2C (i.e. business to consumer) refers to a transaction that takes place between a business organization and an individual consumer (i.e. individual citizens). Disintermediation is the removal of one or more intermediaries (such as a distributor, wholesaler, broker or agent) in a supply chain (known colloquially as ‘cutting out the middleman’). This is a common feature of e-commerce, especially B2C e-commerce. The Internet is also being used by organizations in their dealings with suppliers. For example, the use of online auctions can enable companies to attract bids from many more potential suppliers than would be economically viable using more traditional means. For many years, large organizations have usually conducted much of their business with their suppliers through electronic data interchange (EDI) systems, improving information flows between the companies, allowing them, for example, to enable exact order requirements and for stock positions to be updated instantaneously. Now the Internet has dramatically reduced the cost involved in operating EDI, enabling companies of any size to make use of its benefits. Global positioning satellites have enabled the exact location of goods in transit to be tracked. ICTs are also used by organizations to enable workers in different locations to work together effectively. This has been particularly pronounced in the separation of front and back office operations in some service organizations. In all cases, the impact of technology is to shrink distance, reducing the importance of proximity between supplier and customer. It is also worth noting the impact that improvements in technology in the latter half of the twentieth century have had on the speed and cost of transportation of both goods and people. Advances in air travel mean that virtually any part of the inhabited world can be reached from any other in less than a day. Improvements in transport infrastructures on both land and sea, and in transportation systems (particularly the near universal adoption of containers), have led to dramatic reductions in the total time taken to transport goods. Taken together with the impact of Internet-based ICTs, the world can truly be said to have shrunk. Political For almost half a century after the Second World War, the world was essentially divided into three groupings. The industrialized countries of the ‘West’ (North America, Western Europe and Japan) manufactured most of the world’s goods and accounted for most international trade. The USA was the most dominant political and economic force as the European powers and Japan recovered from the devastation of war. Second, the ‘communist bloc’ of the Soviet Union and Eastern Europe sought to create its own economic system quite separate from that of the capitalist West. The rest of the world outside of these two groupings was the ‘Third World’. This comprised the mostly poor and underdeveloped countries that were often the sources of the world’s raw materials and food. Many countries were emerging from colonialism during this period and some became battlegrounds (usually metaphorically, but sometimes literally) between the competing interest of the West and communism. Re-intermediation is the reintroduction of an intermediary in a supply chain. The growth of ecommerce has prompted the emergence of new kinds of intermediary in many industries. Electronic data interchange (EDI) is the computer-to-computer exchange of structured information via a telecommunication link. EDI has been used by business since the 1970s and there are agreed international standards covering its use. It is still used by many MNEs to automate their purchase of goods and services. An increasingly important political development since the Second World War has been the emergence of international agencies to promote international trade and development, such as the WTO, the IMF, the AIIB and the World Bank. Most countries belong to such agencies. The World Trade Organization (WTO) negotiates agreements between governments that govern the rules of trade between nations. It has promoted trade liberalization by brokering deals that have progressively lowered trade barriers and tariffs between countries. The International Monetary Fund (IMF) promotes international monetary cooperation and provides temporary financial assistance to countries in financial difficulty. The Asian Infrastructure Investment Bank (AIIB), initiated by China in 2009, supports the building of infrastructure in the Asia-Pacific region. The World Bank provides lowcost finance to developing countries for education, health and infrastructure projects. Although the economic development of many Third World countries has been disappointing, some have advanced significantly and are now considered as newly industrialized economies (NIEs). O’Neill (2001) coined the acronym BRICs for what he saw as the strongest NIEs, namely Brazil, Russia, India and China. The intervening years have seen somewhat mixed performances from the economies of these countries. Most notably, China has become the world’s second largest economy (after the US). It is the world’s largest manufacturing economy, and the largest trading nation, being the largest exporter and second largest importer of goods (IMF, 2014). As such, it should perhaps not now be considered as an emerging economy at all. As well as adding South Africa to the list of BRICs, O’Neill went on to invent the further acronym MINT for the next group of countries, Mexico, Indonesia, Nigeria and Turkey, assessed as significant NIEs (Magalhaes, 2013). The emergence of countries such as these is characteristic of the changing economic order in the rapidly globalizing world. As well as cooperating globally to promote increased international trade, countries have also done so regionally to create formal trading groups. The first of these was the European Union (EU). Originally formed by six countries in 1957 as the European Common Market, the EU now encompasses 28 countries. While there is the prospect of others joining in the future, the UK announced its intention to quit the organization in 2016. Free trade is a central tenet of the EU. ASEAN (the Association of Southeast Asian Nations) comprises 10 South East Asian countries who have pledged to create the ASEAN Economic Community as a free trade zone. A similar free trade agreement, the North American Free Trade Agreement (NAFTA) was set up between the US, Canada and Mexico in 1994. Further moves to promote free (or at least freer) trade between groups of countries have been given currency by the Trans-Pacific Partnership Agreement (TPPA), to which 12 Pacific countries are signatories, and the Transatlantic Trade and Investment Partnership (TTIP) between the US and the EU. The creation of free trade blocs such as these can particularly impact decisions about where companies choose to locate their production and service delivery facilities. Locations within a country that can offer tariff-free access to all of the countries within its trading block are usually seen as highly attractive for firms seeking to access and penetrate those markets. Sociocultural The last two decades have seen an increase in the movement of people around the world. More open borders and cheaper travel costs have contributed to the numbers migrating, both legally and illegally, to seek work and improved economic circumstances, or to escape war and persecution. More people travel greater distances to take holidays. Many young people now often undertake extended periods of travel, sometimes including short periods of work, typically before going to university or taking a permanent job. Many students now choose to study in universities outside of their homelands. Satellite television and the Internet make it possible to learn about life in other countries very quickly. People all over the world now aspire to access the same products and services that might previously only have been available in the more advanced economies. This has fuelled the trend for global products that have the same level of quality wherever in the world they are produced and consumed. The world may not yet be a global village, but many people now feel themselves to be citizens of the world as much as citizens of their country of origin or current residence. Economic Until the financial crisis of 2008, the period since the end of the Second World War had seen the most sustained period of economic growth in modern history. Despite the economic difficulties suffered by many countries in the aftermath of 2008, in many ways it was the financial stability and mostly continuous growth experienced in the preceding several decades that have underpinned the forces of globalization. While the US and the countries of Western Europe were the driving economies for much of that time, the emergence of new manufacturing centres in the NIEs of South East Asia (e.g. South Korea, Taiwan, Singapore, Hong Kong, Malaysia, Thailand, the Philippines, Indonesia), Latin America (e.g. Brazil, Mexico) and particularly China has provided a major stimulus to the world economy. As previously discussed, the growth in the international trade in services has become a notable feature of the world economy in recent years, far outstripping the growth in manufactured goods (WTO, 2014). Advances in technology have enabled more services to be traded internationally, especially in financial services and ICT. Of the developing countries, India has been particularly successful in benefiting from this trend. Finally, in discussing the economic drivers of globalization, the role of MNEs should be noted. These are among the world’s largest businesses and they operate in countries outside of their homeland. They include familiar names such as Exxon Mobil and Royal Dutch Shell (oil companies), General Motors and Toyota (carmakers) and Apple and Samsung (electronics manufacturers). Indeed, their activities often span the globe and their products can be found in virtually every country. The financial value of the activities of such businesses can exceed that of many nation states. The decisions taken by their executives can have a greater impact than that of many government ministers. Unlike governments, their decisions are taken not in pursuit of national interest, but rather in pursuit of growth and profits for their shareholders. Their decisions, about where to locate their operations and where to source their suppliers, can have significant impacts on the economies of the countries involved. In most countries, MNEs can take advantage of the freedoms afforded by banking and financial systems that operate electronically on a 24-hour basis to transfer funds unhindered from government restrictions. Thus, many MNEs are powerful economic forces in their own right that often act independent of national governments. Internationalization theories In the face of the forces of globalization discussed above, more and more organizations have been internationalizing their business operations. Although some businesses have always operated internationally, these have generally been small in number but very large in size, as typified by large multinational enterprises (MNEs). A number of theories explaining this internationalization process have been promulgated, including: Vernon’s product cycle theory Vernon (1966) offered an analysis of the internationalization process. The essence of this theory is that production increasingly moves away from the place of origin over time in a series of identifiable phases. Vernon identified five such phases based on the product lifecycle model: »Phase 1 – Introduction: All export markets are served from production in the home country. »Phase 2 – Growth: Production facilities set up in high-income markets to serve local markets. Lowincome markets in less developed countries (LDCs) continue to be served from production in the home country. »Phase 3 – Maturity: The newer lower-cost facilities in the high-income markets export to LDCs, displacing exports from the home country. »Phase 4 – Saturation: The newer lower-cost facilities in the high-income markets export to the home country. »Phase 5 – Decline: Newer lower-cost production facilities set up in LDCs, which export back to the home country. Vernon’s theory was based on his analysis of the overseas investments of US corporations and his prediction of likely future events. A frequently cited example of a product that followed the theories of pattern of invention, growth and production is that of the personal computer and the US, where the PC was invented and first manufactured. However, modern critics argue that his theory does not explain more recent patterns of internationalization. They maintain that his model is too simplistic in today’s much more complex world. Dunning’s eclectic theory Dunning (1976) argued that a firm will engage in international production at a particular location when all of the following three conditions are present: »Ownership-specific advantages: The firm must have access to assets not possessed by competing firms. Such assets might be tangible (e.g. raw materials, plant and machinery, skilled labour) or intangible (technological or marketing know-how, patents, brand names, management expertise). Large firms tend to be better placed to internationalize as they usually have access to greater amounts of finance at lower cost. »Location-specific factors: There must be factors at the foreign location that make it more advantageous for the firm to locate its operations there rather than at home. These factors might include access to markets, the availability of resources, lower production costs, favourable political conditions and cultural/linguistic affinities. The importance of each will vary depending on the type of activity taking place. »Internalization: The firm must internalize the use of its ownership-specific advantages at the location, exploiting them itself, rather than selling them or leasing them to other firms. Dunning’s theory is sometimes known as OLI, in reference to the three factors. Although some critics argue that it is more a list of factors rather than a theory, it offers a useful framework to examine specific cases of internationalization of operations. Stage theories Various authors have argued that firms internationalize in a series of incremental sequential stages. A number of different models describe the various stages that have been put forward. The best known of these is the Uppsala model (Johanson and Wiederscheim-Paul, 1975), which identifies four stages: »Stage 1: No regular export activity. »Stage 2: Export to foreign countries via local sales agents. »Stage 3: Establishment of a wholly or part-owned subsidiary company in order to sell directly to the foreign country. »Stage 4: Establishment of production facilities in the foreign country. Ohmae (1994) adds two further stages beyond the Uppsala model. Ohmae’s stage 4 (his stage 1 equates to Uppsala’s stage 2, as he omits Uppsala’s stage 1) is complete insiderization. At this stage, the firm becomes an ‘insider’ in the markets it services, with all the resources necessary for that, including R&D, production and marketing. This requires the diffusion of organizational activities to different locations around the world, to meet the needs of each of the different markets. The fact that various functional activities have become replicated around the world is likely to lead to tensions within the organization, with national managers attempting to meet the specific requirements of local markets clashing with those at headquarters trying to coordinate and control disparate efforts around the globe. Ohmae’s stage 5 is true globalization. This requires all members of the organization to make a mental adjustment and adopt a truly global mindset. This is one where the loyalty of each employee is to the firm as a global entity, not to the headquarters or the country where they work, and the focus is on meeting the needs of customers irrespective of where they are located in the world. Overcoming of the problems caused by the dispersion of operations and functional activities around the world leads to a new role for senior managers at corporate head office. Their role becomes one of guarding corporate identity. As such, they will focus their efforts on controlling branding and ensuring that corporate policies can meet the needs of all stakeholders across the globe. Thus, Ohmae’s stage model has the following stages: »Stage 1: Export via agents. »Stage 2: Establishment of a sales subsidiary in the foreign country. »Stage 3: Establishment of production in the foreign country. »Stage 4: Complete insiderization. »Stage 5: True globalization. Stage model theories of internationalization have been criticized in a number of ways. First, they are based on analyses of how a relatively small number of companies have behaved in the past. They do not adequately describe how all companies have internationalized. Some empirical studies have shown that some companies have followed a number of different paths to the establishment of foreign production facilities, skipping one or more of the stages (e.g. Turnbull 1987; Clark et al., 1997). Indeed, some companies can be ‘born global’ (Rennie, 1993), operating in international markets on a substantial scale from their earliest days. Furthermore, some companies have behaved differently when entering different overseas markets. Second, the models do not mean that all companies must or will follow these stages in the future. The stage models do not necessarily represent best practice, and organizational strategists may well be able to devise other ways to internationalize. Finally, all stage model theories seem to assume that internationalization is marketled, with organizations entering particular countries to meet an identified market need in that country. However, as will be discussed in Chapter 3, strategy can also be operations-led. Establishing operations in one foreign market may be part of a process of building knowledge and expertise that can subsequently be used, not only to expand further into that market, but also as a springboard for entry into other markets. Lessons learnt from experiences in one market can be used to inform and shape actions in others. THE INTERNATIONALIZATION OF SERVICES Most of the theories about internationalization discussed above are implicitly, if not explicitly, based only on a consideration of manufacturing organizations. This may have been understandable up until recently, as there have been few instances of service-based organizations operating internationally. However, services have become increasingly important and now represent the overwhelming majority of economic activity in industrialized countries. Also, it is fairly easy to think of examples of service providers that do operate internationally (e.g. the banking and financial services, media, telecommunications, business services industries). So, are we to simply assume that service organizations internationalize in exactly the same way as manufacturers? Or, should services be considered as a special case? One of the most important distinctions made between services and manufacturing is that of customer contact. Manufacturing does not usually require any direct customer contact. However, back office services do not require direct customer contact either. A great deal of the internationalization of services in recent years has taken place in back office services. The offshoring of back office service operations has often been driven by a desire to move labour-intensive support services to low labour cost locations. India has especially become a favoured destination for the offshoring of back office services. Some companies have chosen to set up their own back office operations in foreign countries. Others have outsourced these operations to locally owned external providers. Back office operations can be viewed as another form of manufacturing, and so in many respects it seems quite legitimate to consider their internationalization as being akin to that of manufacturing operations. Outsourcing is one of the terms used to describe the process of obtaining inputs of goods or services from sources outside of the organization. Front office operations, however, appear to be different, as these require some degree of customer contact. So where and how that contact takes place is a key element in these operations. The facilitation of contact between service provider and service user may necessitate one or other of them to move. The service provider may need to move to meet the service user. The service user may need to move to meet the service provider. Front office services can be categorized on the basis of a 2x2 matrix formed by considering these movements (see Figure 1.4). Separated services These are services where there is no need for face-to-face physical contact between service provider and user. Contact in these services is typically technology-mediated in some way, as is the case for telephone and Internet services. Technological advances have seen an increase in cross-border separated services. Telephone call centres are an obvious example. Reductions in the cost of telecommunications have fuelled the vast increase in the offshoring of call centres, especially to India and other low labour cost countries with an abundance of well-educated English speakers. The widespread availability of the Internet has made it possible for businesses and consumers alike to conduct most commercial transactions online. Increasing bandwidth is making Figure 1.4 Customer contact service location matrix Source: inspired by ideas in B890 International enterprise (1995-2002) The Open University. it possible to deliver many services online via the Internet for the first time. This is especially so for entertainment. It is now possible to download music, videos and movies from the Internet. Internet technology is advancing rapidly and the possibilities seem unlimited. Technologically speaking, the location of an online service provider has become irrelevant. This is opening up new approaches to the internationalization of any service that can be digitized, and our understanding of the internationalization process seems certain to be challenged. Demander-located services Some face-to-face services need to be provided at the user’s location, with the provider needing to move to deliver the service. Management consultancy is one example of such a demander-located service. Some industrial services such as the repair and commissioning of equipment also fall into this category. The internationalization of this type of service requires the provider to have the capability of delivering the service in the user’s country. This clearly has implications for the skills required by the service delivery personnel, the provision of any necessary equipment they require, the cost of delivery, and so on. Provider-located services The provision of some face-to-face services requires the user to move to the provider’s location. This is often the case where the service needs specialist equipment or staff, as is often the case for medical services. Some services are provided specifically for users who are themselves travelling, whether for business or pleasure (e.g. in the hotel and hospitality industries). Sometimes the user travels to the provider’s home country to receive the service, as is the case for some specialist medical treatments. However, more normally, this category of service requires the provider to establish service provision locations to suit the user. This clearly has implications for internationalization. Peripatetic services Although they are more unusual, there are services where the provider and the user both move in order to facilitate the service encounter. Trade shows, conferences and some live entertainments fall into this category. The encounter needs to take place at a location suitable for the event, so both service providers and users need to have the ability to access such venues. Internationalization normally creates a conflict between the pressure to standardize provision globally in order to maximize economies of scale and scope, and the pressure to customize in order to meet the different requirement of customers in each locality. Services have traditionally been seen as being more difficult to globalize because of the imperative to tailor the service offering to meet different local needs. This is particularly true for front office services where the requirement of customer contact makes them fundamentally different to manufacturing. This ought to prompt a somewhat different consideration of the internationalization process for at least some types of services. However, with some exceptions (e.g. Segal-Horn, 2005), the development of theory of the internationalization of services has lagged that for manufacturing. IFFERENT TYPES OF OPERATIONSOperations can be classified into three different types depending upon which type of primary input is principally being transformed in the operation: »Material-processing operations are those in which materials are transformed either from one form to another, and/or from one place to another. Manufacturing operations in which raw materials and components are transformed into finished products fall into this category (e.g. manufacturing a car or producing a garment). Other material-processing operations include mining, and the transport, storage and distribution of goods in warehousing and retailing operations. »Information-processing operations are those in which information is transformed from one form to another and/or from one place to another. There are many examples of information processing, including accountancy, banking, financial services, telecommunications and research of all kinds. Nowadays, it is difficult to think of information-processing operations that do not involve the use of computers. »Customer-processing operations, in which the customer is transformed by the operation. There are many examples of this type of operation, including medical services (e.g. hospitals) in which sick people are, hopefully, made well, education, where people are transformed by gaining additional knowledge or skills, and entertainment, where people are transformed by the emotional benefit gained from the event. While one of these types of processing often predominates in any particular operation, many operations also typically involve two or even all three types. For example, a restaurant processes both materials (food) and customers; a book publisher processes both information (the text for the book) and materials (the paper, ink, etc.); and an airline processes customers (passengers) and materials (their baggage). TOYOTA: THE WORLD’S NUMBER ONE With global sales now at 10 million vehicles per annum and climbing, Toyota finds itself as the world’s leading auto manufacturer. US giant General Motors, which had previously held this title for 74 years, was dethroned in 2006, and the Japanese automaker has not looked back since. In a financial climate in which most of the top automakers have experienced declines both in sales and profits, Toyota stands out for its burgeoning financial returns, which are not restricted to the established US market, following investment in China’s developing market. Environmental and technological advancement, in the form of its part-electric, part-petrol hybrid models, also creates healthy demand. Toyota’s Lexus subsidiary also taps into the US luxury market, propelled in 2016 through its RX crossover model, which exceeded sales forecasts. Despite the fact that it dates back to 1937, Toyota rose from relative obscurity in the 1950s through Taiichi Ohno’s development of the Toyota Production System (TPS). Based on Japanese principles such as jidoka (referring to human automation), muda (elimination of waste) and kaizen (continuous improvement), TPS enables greater cohesion within the manufacturing process, particularly with regard to team- and management-based tasks. In an industry that is so dependent on intricate supplier collaboration, it has been claimed that TPS helps to achieve this end, insofar as it minimizes defects. The eradication of such design flaws also allows newly created products to reach the customer in a shorter time than can be achieved by other companies, and with a greater level of quality control. Getty Images/Hero Images This approach to production has been researched and emulated by a number of international carmakers and is now considered the industry gold standard, while also finding traction within other sectors. Now articulated as ‘lean’ production, numerous service environments have also incorporated this approach. One such surprising application of TPS methodology can be found within the field of healthcare, in which the traditional focus upon meeting objectives is replaced with the prioritization of processes. Each role within the organization is defined in terms of key competencies, and, as these are met, patient needs are satisfied with greater consistency. TPS has been regarded as the secret to Toyota’s success, implementing increased flexibility and productivity while eradicating many of the production errors that plague other car manufacturers. As a result, the company does not need to resort to competitor-minded discounts in order to satisfy a customer base that is happy to pay for quality. As Toyota continues to outperform its rivals for a fourth consecutive year, it now contemplates consolidating its position through business partnerships with manufacturers such as Daihatsu and Suzuki. And yet, at the heart of this increasingly outward-looking company remain the streamlining qualities facilitated through the TPS, which acts as an integral foundation for such growth. ERVICE OPERATIONSOperations can be classified more simply in terms of their outputs, as either goods or services. The factors that distinguish them are: »Tangibility: Goods are physical products that can be touched, seen, tasted or smelled. As physical entities, goods can be stored and transported. The ownership of goods can be transferred from the supplier to the customer. Services, on the other hand, are intangible, and therefore unlikely to possess any of these properties. »Simultaneity: Services are distinguishable from goods in that their production and consumption usually takes place simultaneously. As such, it is usually not possible to store a service that has just been produced for consumption at some time in the future. Normally, customers have to be present to receive the service when it is produced. On the other hand, goods can usually be stored ready for future consumption by a customer. »Customer contact: Because of their intangibility and simultaneity, services normally require some degree of contact with the customer, although the degree of that contact can vary. Similarly, some services are much more labour-intensive than others, and might involve the customer coming into contact with large numbers of employees of the service delivery organization, such as in a visit to a hospital or staying in a hotel. »Quality: Because of the nature of the output of a service operation, it is much more difficult to define and measure the quality of a service. The quality of a product can be defined and measured in terms of its functionality (i.e. its fitness for the purpose for which it is intended). The quality of a service, on the other hand, can often only be judged by its recipient. Service quality is dependent on the perception of a customer. Such perceptions may vary between one customer and another, and between the customer and the service deliverer. As such, service quality often depends upon the psychological state of a customer at the time of consumption. Indeed, some services are intended to change a customer’s psychological state. Services are the intangible outputs from an operation. It is possible to think of examples that equate to the extremes of pure goods (coal mining) and pure services (psychotherapy). However, a closer consideration of the outputs of most operations reveals that it is rare to find such extremes. Usually, there are elements of service in most goods-producing operations. For example, even extractors of commodity goods such as coal or oil typically provide their customers with information about their chemical composition or offer technical advice on their use. Similarly, even producers of a highly customized service such as management consultancy will usually produce some tangible output, such as a written report of some kind. It is usually more helpful to think of the outputs of operations as being located somewhere on a continuum between pure services and pure goods (see Figure 1.2). Many service operations are different from those in manufacturing, in that they usually require the operation to have some degree of contact with the customer. Organizations that treat their customers in the same way that they treat the inanimate objects that are materials are neither likely to retain existing customers nor attract new ones. The study of service operations has led to the development of some useful concepts in addition to those that have emerged from the study of manufacturing. One such concept is that of the difference between the front office and the back office. The area in which contact with customers occurs is termed the front office. This primarily involves customer-processing operations. The area where there is normally no contact with customers is termed the back office. This may involve information- and/or material-processing operations (see Figure 1.3). The transforming resources required in the front office are likely to be significantly different than those needed in the back office. In particular, operations in the front office need to revolve around the customer. The people that work in the front office are likely to require quite different skills than those in the back office. Front office staff need high levels of interpersonal skills if they are to interact successfully with customers. The physical resources used in the front office, buildings, machinery and equipment may also need to be quite different from those in the back office. Indeed, the front and back offices may well be physically located in quite different places. However, the relationship and interaction between front and back office operations is often a key part of the management of operations. The front office is the area of an operation in which contact with customers normally takes place. The back office is the area of an operation in which there is normally no contact with customers. HE TRANSFORMATION MODELAny operation can be depicted as a transformation process that converts inputs into outputs of goods and services (see Figure 1.1). For the inputs, it is useful to distinguish between: »The primary inputs that are themselves transformed to become part of the output of the operation. These are sometimes referred to as ‘transformed resources’ (Slack et al., 2013). Primary inputs can be materials and/or information and/or customers. »The resources necessary to carry out the transformation, but which do not themselves form part of the output. These are sometimes referred to as ‘transforming resources’ (Slack et al., 2013). Figure 1.1 The input-output transformation model for operations Source: adapted from Operations Management, 7th edition, by Nigel Slack, Alistair Brandon-Jones and Robert Johnston, Pearson Education Limited. © Nigel Slack, Stuart Chambers, Christine Harland, Alan Harrison, Robert Johnston 1995, 1998. © Nigel Slack, Stuart Chambers, Robert Johnston 2001, 2004, 2007, 2010. © Nigel Slack, Alistair Brandon-Jones, Robert Johnston 2013. These can typically be classified as: »Facilities: These are the resources that are necessary to undertake the operation, but which are not used up in the operation. Typically, these include the land, buildings, equipment and vehicles used by the organization to perform the operation. These resources are usually intended to be used over several years. Consequently, they are normally designated as fixed assets by accountants, and their value appears in the fixed assets column of the balance sheet. »Consumables: These are the resources that are used up as part of the operation. Examples include the energy necessary to power buildings, plant and machinery, and the materials necessary to maintain, repair and operate them (often referred to as MRO supplies). »People: The human resources necessary to undertake the operation. These will usually include the staff of the organization. However, employees of other organizations might also be involved in the transformation process, for example those belonging to the suppliers or subcontractors of the organization undertaking the operation. The transformation model sees operations management as those activities that are concerned with how these resources are managed in order to produce the required outputs of goods and services. DIFFERENT TYPES OF OPERATIONS Operations can be classified into three different types depending upon which type of primary input is principally being transformed in the operation: »Material-processing operations are those in which materials are transformed either from one form to another, and/or from one place to another. Manufacturing operations in which raw materials and components are transformed into finished products fall into this category (e.g. manufacturing a car or producing a garment). Other material-processing operations include mining, and the transport, storage and distribution of goods in warehousing and retailing operations. »Information-processing operations are those in which information is transformed from one form to another and/or from one place to another. There are many examples of information processing, including accountancy, banking, financial services, telecommunications and research of all kinds. Nowadays, it is difficult to think of information-processing operations that do not involve the use of computers. »Customer-processing operations, in which the customer is transformed by the operation. There are many examples of this type of operation, including medical services (e.g. hospitals) in which sick people are, hopefully, made well, education, where people are transformed by gaining additional knowledge or skills, and entertainment, where people are transformed by the emotional benefit gained from the event. While one of these types of processing often predominates in any particular operation, many operations also typically involve two or even all three types. For example, a restaurant processes both materials (food) and customers; a book publisher processes both information (the text for the book) and materials (the paper, ink, etc.); and an airline processes customers (passengers) and materials (their baggage). ERFORMANCE MEASUREMENTPerformance measurement is the process of quantifying actions taken to improve performance. ‘If you can’t measure it, you can’t manage it’ is a phrase that encapsulates the role and importance of performance measurement in operations management. At its most basic, the purpose of performance measurement is to keep score. On first examination, performance measurement might seem a fairly straightforward matter. Just decide what aspects of performance are important and measure them. However, a deeper consideration raises a number of questions and issues. First, performance objectives are usually expressed in numerical form. For example, cost objectives need financial measures, while speed and dependability objectives need measures of time. This, of course, assumes that the aspects of performance that managers are interested in can be quantified. Sometimes this is not easy. For example, many aspects of quality are notoriously difficult to measure (this is discussed in more detail in Chapter 11). Even if quantification is possible, the act of measurement itself has costs associated with it. The more aspects of performance that are measured, the higher the costs are likely to be. So an associated question is, given the costs, how many measures should be used? Second, how do you determine what aspects of performance should be measured? Another important maxim in performance measurement is ‘what gets measured gets done’. This is because the act of choosing a particular measure focuses attention on that aspect of performance, usually with the specific intention of achieving a desired outcome. Indeed, performance measures are usually chosen to measure progress towards achieving one or more specific performance objectives. Thus, the choice of what to measure becomes a key decision. It immediately signals what is seen to be most important to the organization’s operations, and hence what will become the focus for management attention. The measures seen to be of most concern to managers will be the measures people inevitably focus on. Of course, for most organizations, ‘keeping score’ is only the starting point for performance management. They will usually want to take actions that will improve performance in the light of the measurements being taken. What is measured is vitally important because it will influence people’s behaviour in one way or another. Indeed, much of the purpose of performance measurement is to have a behavioural impact, to focus people’s attention on actions that will improve the chosen measures. In some organizations, this intention is emphasized and reinforced by offering rewards, often monetary, that are based on the achievement of specified performance measurement targets. Performance-related pay, whether for shop floor workers or for senior executives, remains popular. The whole point of such schemes is to provide direct financial incentives to people to improve whatever performance measures are used as the basis for the scheme. It is important that such measures do promote the kind of behaviour desired by the organization. There is a very real danger that placing too much of an emphasis on certain performance measures can promote the kind of behaviour that is not considered desirable and lead to unintended consequences. It may be that the pursuit of a single performance target leads to other facets of performance being downplayed or neglected. For example, many call centres have minimized the time it takes to answer the phone as their prime performance objective. However, at periods of peak demand, that risks operators rushing their responses to enquirers in order to move quickly on to the next caller. Callers may then feel that the quality of service given to them has been poor because their enquiries have not been fully answered and that the operator has been abrupt or even rude to them. An overzealous pursuit of performance targets can also risk unscrupulous actions by some employees. In extreme cases, it may even be that employees simply falsify records. PERFORMANCE MEASURES As discussed, determining what to measure is a key issue for performance measurement in operations. The transformation model of operations (see Chapter 1) can be used as one basis for classifying performance measures. Three types of measure can be identified dependent upon the point in the process that they provide information about. These are measures of economy, efficiency and effectiveness (see Figure 2.1.). This classification is often referred to as the three Es of performance measurement, as it comprises measures of: The three Es of performance measurement are economy, efficiency and effectiveness. Measures of economy are concerned with the cost of the goods and services required as inputs for the operations process. Economy All organizations wish to acquire the inputs they need for their operations at the lowest possible cost. Measures of economy are concerned with the cost of the goods and services required as inputs for the operations process. While it is clearly important for those responsible for acquiring inputs to achieve the lowest possible purchase price, buying on the basis of price alone is fraught with difficulties. In organizations, it is usually better to consider purchasing decisions on the basis of the so-called five ‘rights’ of purchasing: right quality, in the right quantity, at the right time, from the right supplier, at the right price. Buying goods and services on the basis of price alone risks problems in each of these categories: »Quality: Focusing on price alone risks purchasing goods and services that do not have an adequate specification for their purpose. If suppliers have had to quote very low prices to secure the business, they may be tempted to cut corners to reduce their costs (and thus improve their profit margin), and so endanger quality. »Quantity: It is quite common to be able to negotiate a lower price with suppliers by agreeing to purchase larger quantities. However, purchasing larger quantities than immediately required is likely to involve increased stockholding costs. »Timing: The timing of purchases is vital; too early and stockholding costs will increase, too late and costly delays or disruption may occur in the operations process. Failure to consider this aspect of purchasing risks higher costs. »Supplier: In many respects, choosing the right supplier is the most important aspect of purchasing. Failure to consider the reliability, capability and attitude of any supplier risks problems that are likely to increase costs. In short, a measure that accounts for the total cost of acquisition of goods and services, rather than the purchase price alone, is likely to provide a much more meaningful measure of economy. However, this is often difficult to establish in practice. Figure 2.1 The three Es of performance measurement Measures of efficiency are concerned with the performance of the transformation process itself, in terms of its ability to make optimum use of resource inputs in the creation of outputs. Efficiency All organizations wish to make best use of the resources at their disposal by managing their operations efficiently. A high level of efficiency helps ensure that the organization can achieve low operating costs. Measures of efficiency are concerned with the performance of the transformation process itself, in terms of its ability to make optimum use of resource inputs in the creation of outputs. As such, measures of efficiency within the three Es framework are expressed in terms of a ratio of outputs to inputs. These are often referred to as measures of productivity and derived from the ratio: It is possible to construct a large number of productivity measures for any given operation. Measures might be based on all the outputs from the operation. In the case of a manufacturing operation, this would be the total quantity of products made; for a service operation, this would be the total number of customers served. Alternatively, where an operation produces more than one product type, different measures could be calculated for each different product or service type. For manufacturing, these could be the total quantity of product A, the total quantity of product B, the total quantity of product C, etc. For services, different measures could be produced for different customer types (e.g. for a passenger airline, the numbers travelling in economy, business and first class could be used). Similarly, it is possible to calculate various productivity ratios based on different input factors (such as the quantity of materials used to make a manufactured item or the number of labour hours needed to serve a customer in a service operation). Measures of productivity can either be: Single factor productivity, based on a single input factor (e.g. labour and material costs). For example: or: Multi-factor, combining more than one input factor or: Total factor productivity, which seeks to account for all types of inputs. For example: Each of these measures might be based on input volumes (or quantities) or values. Each will be more or less difficult to calculate depending on the unique circumstances of the particular operation and its organizational and industry context. Each will have its own particular advantages and disadvantages. What is important is to be clear about the use to which any particular measure will be put. Organizations usually focus most on those factors of productivity that they consider to be most important. This is typically dependent on which aspects of their operations are most influential in their sector (e.g. labour, materials, energy, land). Examples of productivity measures typically used in particular types of organization are listed in Table 2.1 below. It is worth noting that these all use single-factor productivity, rather than multi- or total-factor productivity ratios, and so are only partial measures of productivity. Organization Productivity measure Hairdressers Chicken farm Retail shop Power generation plant Paper mill Customers per labour hour Kg of meat per kg of feed Sales per square metre Kilowatts of electricity per ton of fuel consumed Tons of paper per cubic metre of wood Table 2.1 Examples of productivity measures in different industries An electronic component manufacturer has supplied the following financial data (all in US$): 2015 2014 Sales value 70,000,000 44,000,000 Labour costs 30,000,000 20,000,000 Raw material costs 25,000,000 16,000,000 Capital equipment depreciation 2,400,000 1,400,000 Other costs 9,600,000 4,400,000 Compare the labour, material and total productivity for 2015 and 2014. Solution: Labour productivity 2.33 2.20 Material productivity 2.80 2.75 Total productivity 1.04 1.05 While productivity measures are often used as a surrogate for efficiency, another approach to measuring efficiency is to calculate as the ratio of actual output to the expected output. Expected output is calculated in terms of some standard production rate, which is the output that should be achieved by a fully qualified and experienced worker operating under normal conditions. So: or: Standard production rates and times can be calculated using work study techniques. Take the example of a garment factory producing shirts. Work study analysts have calculated that each worker should take one hour to produce a shirt. That is the standard time. So, if the factory employs 100 workers each working 35 hours a week, the standard output from the factory in each week should be 3,500 shirts. If the factory produces 3,000 shirts a week, the efficiency would be 85.7 per cent. Whereas, if the output was 4,000 a week, the efficiency would be 114.3 per cent. Effectiveness All organizations wish to manage their operations effectively by ensuring that their customers believe that they are receiving a high level of value. Measures of effectiveness are concerned with the extent to which the outputs of a process meet the requirements of its customers; as such, they are often much more difficult to determine. One approach is to measure levels of customer satisfaction directly, for example through customer satisfaction surveys. It might also be possible to use indirect measures of customer satisfaction, perhaps based on sales or market share. However, these can be affected by external factors such as actions of competitors and the general economic conditions. Some organizations prefer to use internally derived measures that relate more closely to actions being taken within its operations, such as the numbers of repeat sales or returning customers. Being effective means providing what customers want. Thus, it is important to base measures of effectiveness on an understanding of what customers require from the operation. For example, a restaurant might decide to use the number of people served per hour as a measure of its effectiveness. This might be appropriate for a fast-food outlet, where customers want to be served as quickly as possible. However, such a measure would be entirely inappropriate in an upmarket fine dining restaurant where customers go to savour both the good food and the atmosphere. Measures of effectiveness are concerned with the extent to which the outputs of a process meet the requirements of its customers. To be successful, an organization must manage its operations to achieve high levels of economy, efficiency and effectiveness. The operations function is central to achieving these aims. Achieving low costs by focusing entirely on economy and efficiency is rarely enough to ensure success. Organizations must also ensure that their customers are satisfied with the goods and services they provide for them. Operations management is important because of its impact on the quality, availability, timeliness and reliability of the goods and services produced, as well as its impact on costs. Customers judge the value of what they receive by some combination of these factors. ERFORMANCE STANDARDSThe next question to consider is what the chosen measures used to monitor the performance of an operation can actually tell managers and other interested parties about the success of that operation. A performance measure can only be useful as a means of determining whether an operation is performing successfully if there is some yardstick against which to compare that performance. Answering this invariably requires that there is some comparator against which to assess current performance. This principle is enshrined in the control loop model of operations (see Figure 2.3). A performance standard is the level of performance deemed suitable for use as the target level of performance against which to compare a particular aspect of performance. So the question is what should be used as a comparator? What is required is an agreed performance standard that will serve as a comparator for actual performance. There are a number of possible bases for such a standard: »Internal standards: (a)the organization’s past performance; and (b)the organization’s own targets. »External standards: (a)competitors’ performance; (b)best practice; and (c)market requirements. These are now each discussed in turn. The organization’s past performance The basis of this approach is the use of the organization’s own previous performance as a standard against which to judge future performance. Improvement targets can then be set against those standards. This might have the merit of being considered realistic by those involved, but it also runs the risk of an inward focus, generating complacency. It tends to ignore both what the competition is achieving and what the market may be demanding. If the organization carries out a particular operation in more than one location, however, it could use performance measures that compare one location against another to drive improvement up to the standard of the best-performing operation. This approach can be particularly useful to organizations operating internationally as it enables them to compare the performance of operations in different countries. In this category, the cost of collection and presentation of information should be relatively small. Figure 2.3 The control loop Source: inspired by information in Slack et al. (2013). The organization’s own targets Perhaps the most widely used internal performance standard is the annual budget or target. The budget is normally of paramount importance in most organizations. Indeed, the achievement of budget figures often forms the basis of reward (or punishment!) for many managers. The budget specifies directly or indirectly the level of performance required by particular operations. The main problem with budgets is twofold. First, they are self-determined, and therefore internally focused. Like all internal standards, they can ignore the performance of competitors and the requirements of customers. Second, most budgets are based primarily on financial information. This can make for a very narrow information set on which to measure and assess performance. Internally derived performance measures do, of course, have the benefit of being based on information that should be readily available and accessible. The cost of collection and presentation of such information should also be relatively small. Competitors’ performance In an increasingly competitive environment, it makes sense to adopt performance standards that enable an organization to compare its performance with that of its direct competitors. While it might be possible to do this at an organizational level on the basis of published information, it is usually extremely difficult to access the necessary information to be able to make such a comparison at the level of an individual operation. There are, however, many potential sources of information about competitors at their operations. These include: 1.Published sources: Annual reports, press reports, company literature, analysts’ reports, government reports, etc. 2.Secondary sources: »Interviews with analysts, journalists, academics, etc. »Direct contacts: plant visits, observations, etc. »Indirect contacts: industry associations, technical seminars, trade associations, chambers of commerce, etc. 3.Primary market research: Consumer surveys, trade surveys, industrial market research, etc. 4.Sales analysis: For example, by analysing competitive bids lost and won to identify strengths and weaknesses in comparison to competitors. 5.Product comparison: Reverse engineering of products to assess the level of quality and technical sophistication achieved by competitors. 6.Soft information: Informal information gathered by word of mouth from own and competitors’ employees. While it can be difficult and time-consuming to gather and analyse, such information can provide invaluable insights into the performance of competitors. It may be necessary to piece this together to build up a less than complete picture, but it should be sufficient to draw up some standards based on competitors’ performance. The mere act of putting together such information forces operations managers to look outside their own organization, and can provide insights into how competitors achieve their results. Best practice The intention here is to look beyond direct competitors and identify organizations whose practice in a particular activity is recognized as being the best around. In this respect, at least in theory, an organization could look anywhere in the world for examples of exemplary practices, wherever they can be found. The idea is to use the level of performance achieved through the use of best practice as the standard against which to compare current organizational performance in that particular activity. So, for example, if a manufacturing company wanted to establish a standard for the performance of its customer telephone helpline, it might look to an organization with a strong reputation for answering calls quickly, such as the emergency services. The major advantage of looking to organizations in different industries is that they are not direct competitors, and so are more likely to be more willing to divulge information. Market requirements While looking to external organizations to set performance standards is likely to be more difficult than generating ones internally, it is likely to provide more exacting and challenging targets. However, this approach risks ignoring what must be the most important task of any business: namely, satisfying customers. If organizations are not meeting customer requirements, then it is difficult to accept that they are performing successfully. Arguably, the objective of any organization’s operations is to satisfy customers. Therefore, performance standards should be based upon customer needs and requirements. The task of identifying customer needs is usually considered to be a marketing activity. Various market research techniques have been developed encompassing quantitative and qualitative methods, using both primary and secondary data. However, leaving this task solely to marketers is likely to prove less than satisfactory as the operations function can have much to contribute. People working in operations, particularly service operations, have many contacts with customers and potential customers. They are often well placed to gain an excellent understanding of how well (or badly) the organization’s products and services are currently meeting customer needs. They can provide valuable information that can help establish the level of performance required to meet customer requirements. Also, as customer expectations change over time, usually becoming more exacting, organizations need to continually monitor customer needs and requirements and adjust their performance standards accordingly. BENCHMARKING The term ‘benchmarking’ is commonly used to refer to the application of the ideas of performance standards as discussed above. It is usually used to refer to those practices aimed at comparing the performance of an operation with that of similar operations in other locations. However, the term can have a number of different meanings. At its most basic, it merely involves measuring various aspects of performance in two or more different locations for comparison purposes, the idea being to establish a performance standard that can be used as a target for performance improvement. However, the main strength of benchmarking is when it is applied as a springboard to drive performance improvements. As discussed earlier in the chapter, the act of measuring particular aspects of performance signals its importance to the organization. When accompanied by challenging performance standards, this should galvanize managers to achieve progress towards the targeted level of performance. However, an even more potent aspect of benchmarking is when it goes beyond measuring performance to encompass the study of the practices of the benchmarked organizations. The idea is to compare the organization’s own practices and methods with those used in similar operations by organizations that achieve much better levels of performance. Where deficiencies are found, improvements can then be made based on what has been observed in those better-performing organizations. When used in this way, benchmarking can offer a powerful mechanism to drive organizational learning. As with performance measurement benchmarking, practice benchmarking can be undertaken by making comparisons in a number of different ways. There are three main approaches to practice benchmarking: 1.Internal benchmarking: This is where practice in one of an organization’s locations is compared to that in another. The advantage of this is that information about these operations should be readily available and reliable. It should similarly be fairly easy to gain access to the organization’s other facilities in order to study the practices. It may be that different practices have evolved in different locations due to different contextual factors. Organizations that operate internationally can be particularly well placed in this respect, and hence in a much better position to learn, than those that only operate in one country. The main disadvantage of internal benchmarking is that even the best level of performance within the organization may be much worse than that achieved elsewhere. 2.Competitive benchmarking: Here, organizational practices are compared to those of direct competitors. This is often felt to be the most effective form of benchmarking as competitors are likely to be operating similar processes. Competitors are easy to identify, but they may not be very enthusiastic about allowing a direct competitor to learn from them, and thereby endanger their competitive advantage. One way to overcome this in service businesses is to observe a competitor’s front office operations from the perspective of a customer. It is more likely that an organization will allow their operations to be studied by someone in the same industry who is not perceived to be a direct competitor. Consequently, it might be possible to gain access to study an organization that operates in a different country or one that serves a very different market segment. 3.Best practice benchmarking: Here, practice in a particular operation within an organization is compared to practice in a similar operation in an organization thought to be exhibiting best practice, preferably world-class performance. The idea is to learn from the best performers, wherever they are found. It can be particularly instructive to study similar operations carried out in different industries and in different countries, where different practices may have arisen. The advantage of looking to organizations in different industries, and hence those that are not direct competitors, is twofold. First, it can encourage innovative thinking through using different methods. Second, such organizations are likely to be more willing to divulge information. The disadvantage is that it may be difficult to know exactly where the best practice for a particular operation is to be found. Also, it may prove difficult to apply their working methods in a very different industry. A well-known, if slightly extreme, example of best practice benchmarking is provided by Southwest, the low-cost US airline. They studied the practices of the pit crews at the Indy 500 motor racing circuit in order to help reduce the turnaround time of aircraft between landing and take-off at airports. The extent to which an organization can benefit from benchmarking will depend on the importance it attaches to the exercise. Voss et al. (1998) claim that it is possible to identify four different organizational attitudes towards benchmarking, which are revealed by their responses to the receipt of performance data from a benchmarking exercise: »Can do organizations are those that score badly on operational performance practice but use the benchmarking exercise as an opportunity to take action to improve operational performance. »Can’t do organizations are those that score badly on operational performance practice but fail to use the benchmarking data to take any action. This can often be due to business pressures. »Will do organizations are high-performing organizations that use the results of the benchmarking exercise to take action to further improve operational performance. These are true learning organizations. »Won’t do organizations are high-performing organizations that fail to use the benchmarking exercise to take any further action. These are typically complacent organizations who consider they know all that is needed. The performance of these organizations is under threat in the longer term. Organizations that operate internationally have greater opportunities to benchmark the performance of their operations using comparators from different countries. This is likely to bring significantly more benefits than benchmarking, using only domestic comparators. Organizations that operate internationally not only have direct experience of operating in different national contexts, but are also more likely to value the learning obtained from those experiences. As such, they are much more likely to be open to ideas from outside of their own domestic environment. A major problem with all forms of external benchmarking is finding organizations that are prepared to grant access to outsiders. There is a natural reluctance to reveal organizational secrets that might ultimately finish up in the hands of competitors and potential competitors, or others who might use such information to the organization’s detriment, such as suppliers and customers. One solution to this problem is based on the premise that any organization is likely to want to learn from another. This has led to the setting up of benchmarking clubs. These are networks of organizations that, in order to benchmark their operations against others, are prepared to grant access to others who want to benchmark them. There are many such benchmarking clubs, organized by neutral bodies such as management consultancies and trade associations. For example, the Chartered Institute of Public Finance and Accountancy (CIPFA) runs a benchmarking club to enable local authorities in the UK to compare their performance with peers, thereby identifying areas for improvement. Such bodies are often able to collect a wide range of performance measures from their members, and get their agreement to release them on the condition that they are never revealed on an individual basis, but are instead published as part of industry-wide aggregate figures. PERATIONS STRATEGY – PROCESSThe process of operations strategy concerns the way an organization develops its operations strategy. Operations strategy might come about in a top-down process, being cascaded down as a result of deliberate strategy at the corporate and business levels. An operations strategy might also come about in a bottom-up process, in which a recognizable strategy emerges as a pattern in a stream of actions. Similarly, an operations strategy might be developed in response to market requirements (i.e. market-led) or be based on the capabilities of its operations resources (i.e. operations-led). As illustrated in Figure 3.1, this gives rise to four perspectives on operations strategy (Slack and Lewis, 2014). Each perspective places a different emphasis on the nature of the operations strategy process. Top-down The top-down perspective is one in which the operations strategy is derived from, and is supportive of the organization’s business strategy; in other words, the organization bases its operations strategy of identifying an operation’s ‘task’ to realize its business strategy. This concept is in line with that of the Hayes and Wheelwright stage 3 organization. According to this perspective, devising an operation strategy first requires the organization to identify an operations ‘task’ (Skinner, 1969). The task would be determined logically from the business strategy. Using Slack et al.’s (2013) five operations performance objectives (see Chapter 2) is one way of articulating the operations task. For example, if the organization’s business strategy is one of offering low prices, then the operation’s task should be one of achieving low costs in operations. If the business strategy is based on offering customers fast delivery, the operations task should be one of achieving speed in operations, and so on. An example of this is fast-food restaurant company McDonald’s, whose main task for the operations in its over 35,000 outlets across the world is to ensure consistency. Figure 3.1 The four perspectives on operations strategy Source: adapted from Operations Strategy, 2nd edition, by Nigel Slack and Michael Lewis, Pearson Education Limited. © Nigel Slack and Michael Lewis 2002, 2008. In a multi-business organization, the top-down perspective envisages that operations strategy supports the strategy of each business unit. In a diversified conglomerate, such as India’s Tata, such business units can operate in very different industries (e.g. steel-making, motor car manufacturing, tea production, consultancy, mobile phone operator), each of which may require very different strategies. This then raises the question of whether it is possible to talk of a ‘corporate’ operations strategy. If a corporate operations strategy means commonality in all aspects of operations, then this would only be possible if each business unit had similar business strategies and similar operations tasks. However, some authors (e.g. Hayes et al., 2005) argue that a corporate operations strategy does not mean that every facet of operations must be the same in each business unit. Rather, operations decisions are considered holistically at the corporate level with a view to meeting corporate strategic objectives. A failure to do this means that operations decisions are taken only at the level of the business unit, with a view to meeting the immediate needs of that business unit. The dangers of doing this have been pointed out by Prahalad and Hamel (1990), who caution against letting the needs of the business unit dominate strategic thinking. This can lead to operational competencies being confined within individual business units, thereby restricting their future development, preventing their spread to other business units and limiting opportunities for synergistic developments across the corporation. This can be particularly important in multisite, multinational enterprises. Bottom-up The bottom-up perspective is one in which operations strategy emerges through a series of actions and decisions taken over time within operations. Companies, such as Apple, that rely on constant innovation for their success, provide examples of the bottom-up perspective. In these organizations, actions and decisions might at first sight appear somewhat haphazard, as operations managers respond to customer demands, seek to solve specific problems, copy good practices in other organizations, etc. However, they can build over time to form a coherent pattern recognizable as an operations strategy. The actions taken within this kind of strategy are likely to be characterized by a continuous series of incremental improvements rather than the large one-off technologically led changes that require large capital investments in new plant and machinery. The bottom-up perspective is one in which the organization learns from its experiences, developing and enhancing its operational capabilities as operations managers try out new things in an almost experimental fashion using their workplaces as a kind of ‘learning laboratory’ (Leonard-Barton, 1992). Many of the manufacturing practices that are now considered leading edge (such as just in time, total quality management, statistical process control) were developed in just such a fashion by Japanese manufacturers responding to the constraints placed upon them in the aftermath of the Second World War. One of the problems associated with this perspective is that the organization may not recognize what its operations strategy is. Mills et al. (1998) have developed a technique that aims to overcome this by enabling managers to construct a visual representation of operations strategy as realized. It does this by tapping into the organization’s collective memory (whether written or verbal) to map all the most significant events in operations over the previous number of years. This should enable managers to recognize the patterns that now make up the existing operations strategy. Market-led The market-led perspective is one in which the operations strategy is developed in response to the market environment in which the organization operates. Many FMCG (fast-moving consumer goods) companies, such as Unilever and Proctor & Gamble, offer examples of this perspective. There are a number of approaches in the operations strategy literature that suggest how this might be done. The best known of these is that of Terry Hill (1985). He suggests that an organization’s operations strategy should be linked to its marketing strategy by considering how its products and services win orders in the marketplace. He believes it is possible to identify two types of competitive criteria in any market: market qualifying and order winning. Market-qualifying criteria are those factors that must be satisfied before customers will consider making a purchase in the first place. Order-winning criteria, on the other hand, are the factors on which customers ultimately make their purchasing decision. For example, for many airline passengers, the order-winning criteria is price, with criteria such as destination city, time of flights and convenience of travel to and from airports being market-qualifying criteria. For others, notably business travellers, the order-winning criteria may be in-flight service or total travel time. Consequently, an operations strategy should be developed that will satisfy market-qualifying criteria but excel at order-winning criteria for the market segment that the operations wishes to serve. Platts and Gregory (1990) use an approach that audits the products or groups of products that the organization offers to its markets. The aim is to identify any gaps between market requirements for particular products and services and the performance of the organization’s operations in delivering those products and services. First, the market requirements for the product or service are analysed in terms of various competitive factors (such as cost, quality, reliability). The performance of the organization’s operations against those factors are then assessed. An operations strategy should be developed that will enable operations to match the level of performance required by customers in each of the competitive criteria. Operations-led The operations-led perspective is one in which its excellence in operations is used to drive the organization’s strategy. This is in line with the Hayes and Wheelwright stage 4 organization and fits with the resourced-based view (RBV) of strategy that currently dominates the strategic management literature. The premise of the RBV is that superior performance comes from the way that an organization acquires, develops and deploys its resources and builds its capabilities rather than the way it positions itself in the marketplace (Wernerfelt, 1984; Barney, 1991). Thus, the process of strategy development should be based on a sound understanding of current operational capabilities and an analysis of how these could be developed in the future. This can then provide the basis for decisions about which markets are likely to be the best in which to deploy current and future capabilities, which competitors are likely to be most vulnerable and how attacks from competitors might best be countered (Hayes et al., 2005). Perhaps the best-known example of an operations-led strategy is Toyota, whose operations have been synonymous with the lean production model of operations excellence (see Chapter 10). More recently, Amazon seem to be emerging as an example of operations-led in digital business. Mills et al. (2002) have developed methods through which organizations can apply these ideas in practice. These involve undertaking an analysis of the resources that have underpinned the activities of a business unit over an extended period of time (at least the previous three to five years). Six resource categories, which are not mutually exclusive, are used: tangible resources, knowledge resources skills and experience, systems and procedural resources, cultural resources and values, network resources, and resources important for change. The resources are evaluated against three criteria: value, sustainability and versatility. Resources that individually or collectively score highly in these criteria are considered to be important resources. They are sources of existing or potential competitive advantage to the organization. HE MEASUREMENT OF CAPACITYIn the same way that capacity is difficult to define, it is also difficult to measure. Only in operations producing standardized products using a repetitive process is the measurement of capacity likely to be straightforward. There are essentially two approaches to measuring capacity. One is to measure units of input of a process, the other to measure units of output. So the capacity of a machine might be measured in terms of the number of machine hours available to operate (input), or in terms of the number of items processed (output). Similarly, a hospital might measure capacity in terms of the number of beds available (input), or in terms of the number of inpatients treated. Any operation will have a theoretical capacity. This is normally referred to as the design capacity, the level of output that can be achieved by operating continuously at maximum rate. However, this level of capacity is not likely to be achievable in reality, especially over an extended period of time. Even a plant intended for 24 hours a day, seven days a week operation will need some down time to allow for repair and maintenance to machinery. There may also be unavoidable operating time losses due to machine changeovers, or to allow time for operators to change shifts. Effective capacity is the term used to describe the capacity after deduction of planned stoppages. Actual output is that achieved operating under normal working conditions. That is likely to be less than effective capacity due to unplanned or avoidable stoppages due to machine breakdowns, absenteeism, quality problems, material shortages, and so on. Actual output can be compared to design and effective capacity by calculating the ratios: Design capacity is the theoretical output that could be achieved by operating continuously throughout a given period at maximum rate. Effective capacity is the output achievable in a given period after deduction of output lost due to planned stoppages. A food canning plant is capable of filling 100 cans per minute and is operated for 24 hours days, seven days a week. In a certain week, the record of lost production time and its causes was as follows: »Routine machine maintenance: 21 hours »Product changeovers: 16 hours »Shift changeovers: 9 hours »Routine quality checks: 8 hours »Machine breakdowns: 6 hours »Labour shortages: 12 hours »Quality problems: 7 hours »Material shortages: 5 hours Calculate the utilization and efficiency of the plant for this week. design capacity = 168 hours per week = 1,008,000 cans per week planned losses = 21 + 16 + 9 + 8 hours = 54 hours = 324,000 cans avoidable losses = 6 + 12 + 7 + 5 hours = 30 hours = 180,000 cans effective capacity = design capacity − planned losses = 168 − 54 = 114 hours actual output = effective capacity − avoidable losses = 114 − 30 = 84 hours Calculation of capacity and its use in the calculation of performance figures is often a topic of debate inside an organization. Even if agreement can be reached within a single organization on how to do this, there is typically no agreed or standard approach within its industry, let alone across industry sectors. This makes comparisons very difficult. Any discussion of capacity needs to be approached with extreme caution and a clear understanding of definitions and terminology established before any progress is likely to be made. While achieving a high level of utilization may seem desirable, low figures may not always be indicative of poor performance. This might, for example, be caused by a lack of demand, rather than machine breakdowns, labour unrest or materials shortages. Neither is it always sensible to seek to operate at high levels of utilization. This might, for example, lead to necessary equipment maintenance being ignored. It can also create pressure to carry excess inventory, especially in the form of raw materials and excess labour, to avoid having to stop operations due to input shortages. As discussed later in this chapter, in customer service operations, having insufficient excess capacity can lead to unacceptably long waiting times for customers. FORECASTING DEMAND The challenge of managing capacity is one of matching supply and demand. It would obviously be easier to arrange to provide for an appropriate level of capacity if future demand was known. However, as this is usually not the case, organizations have to try to make some kind of forecast of likely future demand. Forecasting future demand is important both in the longer term and the shorter term. Longer-term forecasts are needed when considering the design of new products and services and when planning future levels of capacity, for example by investing in new facilities and equipment. Shorter-term forecasting is needed in order to manage existing capacity in the most effective and efficient manner. There are many different forecasting techniques, the detailed consideration of which is beyond the scope of this book. There are two basic approaches to forecasting. One relies on quantitative methods, the other qualitative methods. Forecasting is the act of predicting the likely level of future demand for products and services. Forecasting methods can be either quantitative or qualitative. Quantitative methods are either based on time series analysis or causal analysis. »Time series analysis essentially involves extrapolating past data into the future. Analysts use mathematical techniques to look for patterns in the data over time. At its simplest, this might involve merely smoothing out random fluctuations in the data by averaging the data over a longer time period using moving average calculations (e.g. for a month, a quarter, or even a year) or by using exponential smoothing techniques. Sometimes no patterns can be found in the data using such approaches, in which case it might be possible to decompose the data into up to four components: trend, cyclical, seasonal and random. A trend is a gradual change in the data over time. Cyclical movements are recurring patterns in the data occurring over a period of more than one year. Seasonal movements are recurring patterns in the data occurring over a period of less than one year. Random movements are irregular deviations in the data that cannot be predicted. The idea behind decomposition analysis is that if cyclical and seasonal effects can be isolated and understood, then the trend can more easily be separated from random movements. Decomposition analysis relies on more sophisticated mathematical techniques, for which there are a number of software packages available (these are often to be found in standard spreadsheet programs). The advantage of time series analysis methods is that they are relatively easy and cheap to use. However, they are based on the premise that the past can be used to predict the future, which may not prove to be the case. »Causal analysis seeks to identify and model any cause and effect relationship between demand data and some other variable. For example, sales might be related to spending on advertising. Sales of some products are weather dependent; specifically, sales of ice cream and beer are temperaturedependent. Causal forecasting uses techniques such as linear regression, curvilinear regression and multiple regression to establish relationships between demand and one or more variables, and derive a model for their behaviour. The science of econometrics tries to model the behaviour of entire national economies. Like decomposition analysis, causal analysis relies on computer software packages (also often to be found in standard spreadsheet programs). Causal analysis methods are based on the premise that past relationships will hold up in the future. They are more complex, and hence more costly to use, than simple time series analysis. However, increasing levels of complexity and sophistication do not always make for more accurate forecasts. Qualitative methods use subjective techniques based on estimates and judgement to try to predict future demand. There are a number of techniques, including: »Market surveys: Data is collected from customers about their future buying intentions. In mass consumer markets, this is likely to involve conducting a survey of a sample of customers. The accuracy of any survey depends on many factors, including the design of the questionnaire, the use of an appropriate sampling method, and the extent to which customers’ replies can be trusted. Surveys can be costly and time-consuming. »Delphi studies: These involve canvassing the opinions of a panel of experts, questioning them independently about future trends. Their initial views are then collated and circulated anonymously to all group members, who are then each invited to refine their opinions. The process continues until a group consensus is reached. This can then be used to provide a guide to future demand. »Scenario planning: This gives a structure to managers’ thinking about the future. The idea is that a team of experts meet to construct a small number of likely future ‘scenarios’ that the organization might face. Each scenario is based on different combinations of likely future situations. Future demand is then assessed for each of the scenarios. The strength of this technique is that it requires managers to think about how they would respond to a number of different possible futures. In reality, organizations often use a number of different forecasting methods. Unfortunately, none of them have a particularly good record of accurately predicting future demand. The longer the time horizon of the forecast, the less accurate it is likely to turn out to be. Similarly, it is more difficult to forecast in some business contexts and some markets are much more volatile than others. For example, at the moment, some parts of the world have been experiencing very rapid rates of growth. It is very difficult to know whether these rates can be sustained over longer periods of time. Thus, organizations seeking to serve new and unfamiliar markets are faced with high levels of risk and uncertainty. Nonetheless, any forecast is almost certainly better than none. Arguably, the mere act of thinking about the future forces managers to consider how they might best respond to changes in demand, no matter how volatile and rapid those changes might be. Although practising operations managers will invariably call for better and more accurate forecasting, in an increasingly unstable business environment this is easier said than done. It might therefore be better for managers to concentrate more effort on devising ways of increasing flexibility in order to increase the responsiveness of their operations.
