A typical organisation has a finance, marketing and operations function. Operations management (OM) is where the organisation’s goods and services are produced and provided. It is a particularly important functional area involving, in virtually all organisations, the largest amount of total organisational resources. This does not mean, however, that operations is more important than other functions, like marketing, human resources management, finance, etc. On the contrary, operations is best viewed as one of the essential functions of any organisation. The following trends have become focal points, not only in OM but also in the field of management in general, largely because of increased competition: a quality focus (as judged by the customer) at every transformation point; a philosophy of continuous improvement; the use of teamwork for improved production and delivery of products; and flexibility in production/processing for fast delivery. It is in OM, however, that these techniques have particular significance. Literature on Japanese industries, focusing on what contributed to and directly led to Japan’s continued industrial success since the late 1980s, shows that development has been centred on Japanese manufacturing techniques and human resources management. The same has been cited for the success of leading manufacturers in the United States of America. Furthermore, it is widely accepted today that no service organisation can be considered excellent without having sound operations management. OM, therefore, has strategic significance for the competitiveness of any organisation having a business and/or performance focus. This is of particular significance for organisations in this region. The South Pacific business environment has been undergoing drastic changes that have made previous management practices totally outdated. With the advent of deregulation and its accompanying competitive onslaught, organisations need to focus very closely on the efficiency of their operations. For example, the Training and Productivity Authority of Fiji (TPAF) has taken various steps in assisting organisations in improving their productivity levels through better management practices. The bulk of the proposed practices are OM techniques. These techniques are also being promoted and encouraged in other countries of the USP region. On the cover of the MG202 course materials, you will have noticed photographs of different parts of a typical production plant. These photographs were taken at Fiji’s Carlton Brewery Ltd.. I have arranged them logically to show you the different stages in the bottling of Fiji Bitter. You will note that the photographs have been arranged in a U-shape. This is one of the most widely used layout designs. The layout at Carlton Brewery, however, is a little different 1 with attempts being made to accommodate the different machines within as little space as possible without negatively affecting the flow of human traffic. Course content MG202 looks at various principles and techniques that are important for good OM. The Coursebook contains a total of eleven units focussing on core areas of interest in operations management. Unit 1: Introduction to operations management This unit introduces you to the field of operations management. Some definitions are considered closely and we find that it is the function that creates the firm’s primary products (goods and/or services) through the transformation of inputs (raw materials, supplies, etc.) into desired outputs (goods and/or services) using operations resources like people, equipment, factories, etc. This unit also examines how value is added to the inputs, the differences between goods and services, and the measure of productivity. Finally, it focuses on the skills and activities of an operations manager. The significance of this cannot be overemphasised, given the role of OM within the organisation. Unit 2: Historical development of operations management Unit 2 takes us through the history of OM. We find that even though much of the progress in operations management has been made in the twentieth century, earlier developments have played an important role in the way that OM has evolved over time. Here we follow operations management through the Industrial Revolution in England, to the spread of factories in the USA. Our focus is on the numerous individuals who made important innovations and contributions to the development of scientific management and operations management, as well as the Japanese contributions to the development of OM. The unit is concluded by following the phenomenal growth of services in the economies of industrialised nations and the significance it has acquired. Unit 3: Operations strategy and competitiveness In unit 3, we learn to define mission and strategy and link it to functional strategy in organisations. Here we follow the emergence of operations strategy in the late 1960s and how this emergence contributed to companies’ competitive success. Then we describe the four basic types of operations strategy commonly used by companies to gain competitive advantage in the marketplace. Some light is also thrown on the vital role of quality and its implications for the organisation. Unit 4: Forecasting demand In unit 4, the focus moves to the influence of the environment on organisational operations. Organisations are always faced with some degree of uncertainty in the environment that they operate in. In the face of this uncertainty, managers try to make reasonable estimates of what will happen in the future. This is the role of forecasting. In this unit, we examine the different factors that affect forecasting demand. Then we follow the different types of forecasts and learn about a variety of forecasting models such as moving averages and exponential 2 smoothing. Finally, we learn how to evaluate the accuracy of a forecast and follow briefly the computer’s role in forecasting. Unit 5: Product design and process selection In unit 5 we look at the important question of how to design a product and which process to use to produce it in the best possible manner. Product design and process selection are two very important strategic decisions that have implications for all subsequent operations decisions. Here we learn about product and service design approaches and process selection. The traditional product design approach is described and its limitations and disadvantages discussed. Then, the team approach and quality deployment methodology is presented. Furthermore, various types of production and service delivery processes are identified and described. Unit 6: Facility location and layout design Following on from our discussion in unit 5, we focus on identifying a location for the production process chosen. Then we decide how to effectively arrange the departments, processes and their related equipment within the facility. In this unit, we learn to identify the best location for a facility, as well as the most efficient layout. We study some of the techniques used in practice to evaluate location alternatives and to plan layout designs. We then follow some of the major layout types and discuss the advantages and disadvantages of each. Finally, we attempt to identify the different objectives and factors that affect service layouts and select the appropriate layout for service organisations. Unit 7: Operations scheduling and control Unit 7 takes us on to the actual carrying out of operations. Here we focus on scheduling which involves allocating resources (people, equipment, etc.) to the various tasks (or customers in services) that have been identified to complete a given job. These tasks have to be processed in a particular sequence to maximise operational efficiency. In this unit, we consider first the importance of scheduling and follow it briefly in job-shop types of operations. We then look at a number of established rules that can be used in different situations to schedule operations. Finally, we follow in some detail the scheduling problem in services. Unit 8: Production planning Unit 8 takes us into production planning. This is a crucial part of the overall running of operations in any organisation. First we look at aggregate planning and then link it to the master schedule, which drives the actual production run. We focus on managing both independent and dependent demand inventory. We find that planning is closely linked to control in operations in the organisation, and is necessary to ensure both efficiency and effectiveness in operations. Unit 9: Materials management Unit 9 focuses on materials management i.e. the management of materials that are used to produce an organisation’s output. A major part of the inputs that are used for the conversion of inputs into outputs in operations management comprises materials. In this unit, we try to establish why good management of materials is essential for organisational efficiency and effectiveness. Firstly, focus 3 is on the important role of materials handling and some ways in which materials can be handled. Then the unit looks in some detail at the purchasing process, which has crucial cost and quality implications. Finally, management of inventory is considered from a time perspective. Unit 10: Quality management Unit 10 covers in some detail the role of quality in OM. We go briefly through the history of quality management and then focus on quality as an OM strategy. The cost of quality is evaluated in relation to its value to the organisation. Then focus moves onto how quality can be included in designing the product or service. This is an acute feature of total quality management (TQM) because TQM does not consider quality as a separate function. We also consider briefly the weaknesses or shortcomings of conventional design approaches for contrast. Finally, we focus on quality control in the process. Some control techniques are introduced in this regard. Unit 11: Japanese approaches to operations management Unit 11 differs from the previous units in this Coursebook because it does not follow the textbook. Here the focus is on some of the later OM techniques that organisations have been using to: minimise costs; maximise quality levels; and provide timely output for competitive survival in today’s environment. There are various issues that have come to the fore in recent years in the field of OM that help organisations achieve these three strategies. A number of Japanese approaches that have been used successfully to improve operations efficiency and effectiveness are highlighted here. These include just-in-time management, total quality control, kaizen or continuous improvement and small group activity. We conclude the unit with a comparison of the typical US-type factory with the typical Japanese-type factory. This distinction has, however, become somewhat blurred as organisations have taken steps to respond to the challenges of the 1990s. Acknowledgements I have drawn extensively on my research and experiences in Japan to prepare this course. I wish, therefore, to acknowledge the contribution of The Japan Foundation in sponsoring me as a Fellow between 1994 and 1995 in upgrading my knowledge and skills in the field of operations management. Without that fellowship, my expertise in OM, and therefore the quality of the Coursebook, would have been much lower. I wish also to highlight the contribution of my mentor in Japanese Studies, Professor Robert J. Ballon, who not only made available to me the facilities at the International Management Development Seminars (IMDS) of Sophia University but also allocated hours of his precious time to discuss the details of my research and findings in Japan. In addition to this, I have used a lot of local cases throughout the Coursebook. Some of you will be able to identify very closely with the cases I have used as they are very common in nature. I have made a point of using a local factory for the cover of the course materials as the lack of Pacific regional context in 4 available textbooks creates an acute problem in teaching. I wish, therefore, to sincerely acknowledge the assistance provided by Mr. Joe Rodan (Marketing Manager) of Carlton Brewery (of Fiji) Ltd. for having allowed us to photograph and use CBF on our cover. Your challenge Finally, this course is intended to introduce students to the field of OM and create an appreciation of the significance of OM decisions. After going through it, you should be able to look at operations in almost any organisation and identify problems within it. This is because the pursuit for the perfect operations system is a never-ending journey of discovery. In addition to this, you should be able to propose improvements that would enhance the organisation’s efficiency and effectiveness. How do you like that for a challenge? Remember to consider each and every OM issue and problem in practical terms. That is the key to good operations management. Go forth and see how you fare!

The units The course is divided into 11 units, each of which looks at a topic in detail. Each unit in the Coursebook follows a pattern. At the beginning is a table of contents, which lists the main headings of the topic. You should use the contents page to help locate particular information and gain a general idea of what each unit is about. Following the contents page is an overview, a statement of your learning objectives and a suggested time frame for you to study the contents of the unit. Read these sections first as part of your understanding of each unit’s overall structure and what you are expected to achieve after studying the unit. The time frame will help you to plan your studies, but you should regard the suggested time as a guide only as each student has his/her own personal pace of study. Readings from your textbook The main part of each unit focuses on a topic of operations management. The discussion of each topic is supplemented with references to your textbook. The readings from your textbook are designed to expand and explain in more depth the information presented in the main part of each unit. You should take your own notes on each of the textbook readings and if you have any difficulty with any of the content, discuss it with your course coordinator at the satellite tutorials or write to him directly. This icon indicates that you are required to read from your textbook. Case studies To help you understand the information presented in each unit, a number of case studies have been included. These case studies are to help you begin applying the concepts and techniques of operations management to what is happening in organisations on a day-to-day basis. Hopefully, this will enable you to see the link between the theory and practice of particular concepts and techniques and provide a means of learning by doing. 6 Activity At various places throughout the unit, you will see this icon: This indicates an activity that you are required to stop and answer. These questions are intended to help you monitor your understanding of the content and help achieve the learning objectives outlined for each topic. The activities are based on the information presented in the textbook and unit and may also ask you to draw on your own personal experiences and knowledge of operations management “situations or examples”. You will find that usually space is left in the Coursebook for you to complete these activities. However do not limit yourself to the space provided. Whenever you work from the Coursebook always have your exercise book with you for note taking. Summary At the end of each unit is a summary, which provides an overview of the main points discussed. Key terms As part of the summary, you will also find a list of key terms. You should ensure that you understand the meaning and use of these terms as they apply to operations management. Review Questions At the completion of each unit, we have provided a set of review questions that are intended to help you reflect on your learning of the content presented. None of the work has to be submitted, but by doing the questions you could discover problems that you need to follow up by re-study, discussion with friends or colleagues, or at a satellite tutorial or by contacting your course coordinator. This icon indicates a set of review questions for a particular unit, that you should answer. 7 When you have finished a unit, check your mastery against the learning objectives at the beginning of the unit. If you feel you have achieved all the objectives proceed to the next unit. If, after reflection, you feel that you are still confused with some of the information, take some remedial action: review the sections you are having difficulty with or raise your concerns at the next satellite tutorial or by writing directly to the course coordinator. Stop now and spend a few minutes looking through this Coursebook and familiarise yourself with the organisation and features of each unit before proceeding to unit 1. 8
