What Is Operations Management? Production is the creation of goods and services Operations management (OM) is the set of activities that create value in the form of goods and services by transforming inputs into outputs © 2011 Pearson Education, Inc. publishing as Prentice Hall
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 © 2011 Pearson Education, Inc. publishing as Prentice Hall

Why Study OM? OM is one of three major functions of any organization, we want to study how people organize themselves for productive enterprise We want (and need) to know how goods and services are produced We want to understand what operations managers do OM is such a costly part of an organization © 2011 Pearson Education, Inc. publishing as Prentice Hall

Ten Critical Decisions Ten Decision Areas Chapter(s) Design of goods and services 5 Managing quality 6, Supplement 6 Process and capacity 7, Supplement 7 design Location strategy 8 Layout strategy 9 Human resources and 10 job design Supply-chain 11, Supplement 11 management Inventory, MRP, JIT 12, 14, 16 Scheduling 13, 15 Maintenance 17 Table 1.2 © 2011 Pearson Education, Inc. publishing as Prentice Hall
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.) © 2011 Pearson Education, Inc. publishing as Prentice Hall
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.) © 2011 Pearson Education, Inc. publishing as Prentice Hall
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.) © 2011 Pearson Education, Inc. publishing as Prentice Hall
The Critical Decisions Supply-chain management Should we make or buy this component? Who should be our suppliers and how can we integrate them into our strategy? Inventory, material requirements planning, and JIT How much inventory of each item should we have? When do we re-order? Table 1.2 (cont.) © 2011 Pearson Education, Inc. publishing as Prentice Hall
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 How do we build reliability into our processes? Who is responsible for maintenance? Table 1.2 (cont.) © 2011 Pearson Education, Inc. publishing as Prentice Hall

Characteristics of Goods Tangible product Consistent product definition Production usually separate from consumption Can be inventoried Low customer interaction © 2011 Pearson Education, Inc. publishing as Prentice Hall
Characteristics of Service Intangible product Produced and consumed at same time Often unique High customer interaction Inconsistent product definition Often knowledge-based Frequently dispersed © 2011 Pearson Education, Inc. publishing as Prentice Hall

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 © 2011 Pearson Education, Inc. publishing as Prentice Hall
Labor, capital, management The Economic System Inputs Labor, capital, management Transformation 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%). Outputs Goods and services Feedback loop Figure 1.6 © 2011 Pearson Education, Inc. publishing as Prentice Hall

Productivity Units produced Input used Productivity = Measure of process improvement Represents output relative to input Only through productivity increases can our standard of living improve © 2011 Pearson Education, Inc. publishing as Prentice Hall
Productivity Calculations Labor Productivity Productivity = Units produced Labor-hours used = = 4 units/labor-hour 1,000 250 One resource input single-factor productivity © 2011 Pearson Education, Inc. publishing as Prentice Hall
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 © 2011 Pearson Education, Inc. publishing as Prentice Hall

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 © 2011 Pearson Education, Inc. publishing as Prentice Hall
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 © 2011 Pearson Education, Inc. publishing as Prentice Hall
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 © 2011 Pearson Education, Inc. publishing as Prentice Hall
