© 2006 Prentice Hall, Inc.1 – 2 What Is Operations Management? Production is the creation of goods and services Operations management (OM) is the set of activities that creates value in the form of goods and services by transforming inputs into outputs
3
© 2006 Prentice Hall, Inc.1 – 3 Organizing to Produce Goods and Services Essential functions: Marketing – generates demand Production/operations – creates the product Finance/accounting – tracks how well the organization is doing, pays bills, collects the money

7
© 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? Table 1.2 (cont.)
8
© 2006 Prentice Hall, Inc.1 – 8 The Critical Decisions 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? Table 1.2 (cont.)
9
© 2006 Prentice Hall, Inc.1 – 9 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? Table 1.2 (cont.)
10
© 2006 Prentice Hall, Inc.1 – 10 The Critical Decisions Supply-chain management Should we make or buy this component? Who are our suppliers and who can integrate into our e-commerce program? Inventory, material requirements planning, and JIT How much inventory of each item should we have? When do we re-order? Table 1.2 (cont.)
11
© 2006 Prentice Hall, Inc.1 – 11 The Critical Decisions Intermediate and short–term 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? Table 1.2 (cont.)

13
© 2006 Prentice Hall, Inc.1 – 13 New Challenges in OM Global focus Just-in-time Supply chain partnering Rapid product development, alliances Mass customization Empowered employees, teams ToFrom Local or national focus Batch shipments Low bid purchasing Lengthy product development Standard products Job specialization
14
© 2006 Prentice Hall, Inc.1 – 14 Characteristics of Goods Tangible product Consistent product definition Production usually separate from consumption Can be inventoried Low customer interaction
15
© 2006 Prentice Hall, Inc.1 – 15 Characteristics of Service Intangible product Produced and consumed at same time Often unique High customer interaction Inconsistent product definition Often knowledge-based Frequently dispersed
16
© 2006 Prentice Hall, Inc.1 – 16 Goods Versus Services Table 1.3 Can be resold Can be inventoried Some aspects of quality measurable Selling is distinct from production Product is transportable Site of facility important for cost Often easy to automate Revenue generated primarily from tangible product Attributes of Goods (Tangible Product) Attributes of Services (Intangible Product) Reselling unusual Difficult to inventory Quality difficult to measure Selling is part of service Provider, not product, is often transportable Site of facility important for customer contact Often difficult to automate Revenue generated primarily from the intangible service

© 2006 Prentice Hall, Inc.1 – 23 Productivity Challenge Productivity is the ratio of outputs (goods and services) divided by the inputs (resources such as labor and capital) The objective is to improve this measure of efficiency Important Note! Production is a measure of output only and not a measure of efficiency
24
© 2006 Prentice Hall, Inc.1 – 24 Feedbackloop Feedback loop Outputs Goods and servicesProcesses The U.S. economic system transforms inputs to outputs at about an annual 2.5% increase in productivity per year. The productivity increase is the result of a mix of capital (38% of 2.5%), labor (10% of 2.5%), and management (52% of 2.5%). The Economic System Inputs Labor, capital, management Figure 1.7
25
© 2006 Prentice Hall, Inc.1 – 25 Measure of process improvement Represents output relative to input Only through productivity increases can our standard of living improve Productivity Productivity = Units produced Input used
26
© 2006 Prentice Hall, Inc.1 – 26 Productivity Calculations Productivity = Units produced Labor-hours used = = 4 units/labor-hour 1,000250 Labor Productivity
27
© 2006 Prentice Hall, Inc.1 – 27 Multi-Factor Productivity Output Labor + Material + Energy + Capital + Miscellaneous Productivity = Also known as total factor productivity Output and inputs are often expressed in dollars

33
© 2006 Prentice Hall, Inc.1 – 33 Key Variables for Improved Labor Productivity Basic education appropriate for the labor force Diet of the labor force Social overhead that makes labor available Maintaining and enhancing skills in the midst of rapidly changing technology and knowledge
34
© 2006 Prentice Hall, Inc.1 – 34 Service Productivity Typically labor intensive Frequently focused on unique individual attributes or desires Often an intellectual task performed by professionals Often difficult to mechanize Often difficult to evaluate for quality
