© 2008 Prentice Hall, Inc.1 – 7 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
© 2008 Prentice Hall, Inc.1 – 8 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

© 2008 Prentice Hall, Inc.1 – 13 The Critical Decisions Design of goods and services What good or service should we offer? How should we design these products and services? Managing quality How do we define quality? Who is responsible for quality? Table 1.2 (cont.)
© 2008 Prentice Hall, Inc.1 – 14 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 strategy Where should we put the facility? On what criteria should we base the location decision? Table 1.2 (cont.)
© 2008 Prentice Hall, Inc.1 – 15 The Critical Decisions Layout strategy How should we arrange the facility? 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.)
© 2008 Prentice Hall, Inc.1 – 16 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.)

© 2008 Prentice Hall, Inc.1 – 26 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 productivity! Important Note! Production is a measure of output only and not a measure of efficiency
© 2008 Prentice Hall, Inc.1 – 27 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

Some improvements: Stop requiring signatures on credit card purchases under $25 Saved 8 seconds per transaction Change the size of the ice scoop Saved 14 seconds per drink New espresso machines Saved 12 seconds per shot Operations improvements have helped Starbucks increase yearly revenue per outlet by $200,000 to $940,000 in six years. Productivity has improved by 27%, or about 4.5% per year.
© 2008 Prentice Hall, Inc.1 – 30 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
© 2008 Prentice Hall, Inc.1 – 31 Productivity Calculations Productivity = Units produced Labor-hours used = = 4 units/labor-hour 1, Labor Productivity One resource input single-factor productivity
© 2008 Prentice Hall, Inc.1 – 32 Multi-Factor Productivity Output Labor + Material + Energy + Capital + Miscellaneous Productivity = Also known as total factor productivity Output and inputs are often expressed in dollars Multiple resource inputs multi-factor productivity
© 2008 Prentice Hall, Inc.1 – 33 Measurement Problems Quality may change while the quantity of inputs and outputs remains constant External elements may cause an increase or decrease in productivity Precise units of measure may be lacking
© 2008 Prentice Hall, Inc.1 – 34 Productivity Variables Labor - contributes about 10% of the annual increase Capital - contributes about 38% of the annual increase Management - contributes about 52% of the annual increase
© 2008 Prentice Hall, Inc.1 – 35 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
© 2008 Prentice Hall, Inc.1 – 36 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
