Basic Management Functions Planning Organizing Staffing Leading Controlling © 2006 Prentice Hall, Inc. 1–6 scope … Ten Decision Areas Service and product design Quality management Process and capacity design Location Layout design Human resources, job design Supply-chain management Inventory management Scheduling Maintenance Table 1.2 © 2006 Prentice Hall, Inc. 1–7 The Critical Decisions Service and product design What good or service should we offer? How should we design these products and services? Quality management How do we define quality? Who is responsible for quality? Process and capacity design What process and what capacity will these products require? What equipment and technology is necessary for these processes? Location Where should we put the facility? On what criteria should we base the location decision? © 2006 Prentice Hall, Inc. 1–8 The Critical Decisions Layout design How should we arrange the facility and material flow? How large must the facility be to meet our plan? Human resources and job design How do we provide a reasonable work environment? How much can we expect our employees to produce? Supply-chain management Should we make or buy this component? Who are our suppliers and who can integrate into our ecommerce program? Inventory, material requirements planning, and JIT How much inventory of each item should we have? When do we re-order? © 2006 Prentice Hall, Inc. 1–9 The Critical Decisions scheduling Are we better off keeping people on the payroll during slowdowns? Which jobs do we perform next? Maintenance Who is responsible for maintenance? When do we do maintenance? © 2006 Prentice Hall, Inc. 1 – 10 Where are the OM Jobs? © 2006 Prentice Hall, Inc. 1 – 11 Assignment I analyze historical evolution of OM from the ten decision areas view point. © 2006 Prentice Hall, Inc. 1 – 12 Manufacturing vs. service operations © 2006 Prentice Hall, Inc. 1 – 13 Characteristics of Goods Tangible product Consistent product definition Production usually separate from consumption Can be inventoried Low customer interaction Low labor content © 2006 Prentice Hall, Inc. 1 – 14 Characteristics of Service Intangible product Produced and consumed at same time Often unique High customer interaction Inconsistent product definition Often knowledge-based High labor content © 2006 Prentice Hall, Inc. 1 – 15 Operations and process management, • All operations processes. are composed of • A process is an arrangement of resources and activities that transform inputs into outputs that satisfy (internal or external) customer needs. • The process technology is the methods, procedures, and equipment used to transform materials or inputs into products or services. © 2006 Prentice Hall, Inc. 1 – 16 • The difference between operations and processes is one of scale, and there fore complexity. • Both transform inputs into outputs but processes are the smaller version. They are the component parts – the building blocks – of an operation. • So, ‘operations and process management’, is the term we use to encompass the management of all types of operation, • The general truth is that processes are everywhere, and all managers have something to learn from studying operations and process management. © 2006 Prentice Hall, Inc. 1 – 17 operations and process decisions 1. Directing the overall strategy of the operation. A general understanding of operations and processes and their strategic purpose, together with an appreciation of how strategic purpose is translated into reality through how innovation is incorporated into products and services and how much of the total value-adding process should be kept in-house and how much outsourced. 2. Designing the operation’s processes. Design is the activity of determining the physical form, shape and composition of operations and processes, together with the type of resources they contain. © 2006 Prentice Hall, Inc. 1 – 18 Cont… 3. Planning and control process delivery. After being designed, the delivery of products and services from suppliers and through the total operation to customers must be planned and controlled. 4. Developing process performance. Increasingly, it is recognized that operations, or any process managers cannot simply routinely deliver products and services in the same way © 2006 Prentice Hall, Inc. 1 – 19 End of chapter one © 2006 Prentice Hall, Inc. 1 – 20
