Operations and Productivity 1 PowerPoint presentation to accompany Heizer and Render Operations Management, 10e Principles of Operations Management, 8e PowerPoint slides by Jeff Heyl
Outline • What Is Operations Management? • Organizational Design • Decisions in OM • Significant Events in OM • Operations in the Service Sector • New Challenges in OM • The Productivity Challenge • Productivity Example • Ethics and Social Responsibility
What Is Operations Management? Operations management (OM) is the set of activities that create value in the form of goods and services by transforming inputs into outputs Production is the creation of goods and services

The Critical Decisions(1 of 2) • Design of goods and services • Managing quality • Process and capacity design • Location strategy • Layout strategy Table 1.2 (cont.)
The Critical Decisions(2 of 2) • Human resources and job design • Supply-chain management • Inventory, MRP, and JIT • Intermediate & short–term scheduling • Maintenance
Significant Events in OM Figure 1.3
How Important is Manufacturing? In 1978 the United States produced 22% of the worlds manufactured goods. • What percent does the United States produce today? 21% The US is still the largest manufacturer in the world. Although China is growing quickly.

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
Transformation Outputs Inputs The U.S. economic system transforms inputs to outputs at about an annual 2.5% increase in productivity per year. Goods andservices Labor,capital,management Feedback loop The Economic System Figure 1.6
Units produced Input used Productivity = Productivity • Measure of process improvement • Represents output relative to input • Only through productivity increases can our standard of living improve
Units produced Labor-hours used Productivity = 1,000 250 = = 4units/labor-hour Productivity Calculations Labor Productivity One resource input single-factor productivity
Output Labor + Material + Energy + Capital + Miscellaneous Productivity = Multi-Factor Productivity • Also known as total factor productivity • Output and inputs are often expressed in dollars Multiple resource inputs multi-factor productivity

Challenges facing operations managers: Ethics andSocial Responsibility • Developing and producing safe, quality products • Maintaining a clean environment • Providing a safe workplace • Honoring stakeholder commitments
In-Class Problems from the Lecture Guide Practice Problems Problem 3: Joanna French is currently working a total of 12 hours per day to produce 240 dolls. She thinks that by changing the paint used for the facial features and fingernails that she can increase her rate to 360 dolls per day. Total material cost for each doll is approximately $3.50; she has to invest $20 in the necessary supplies (expendables) per day; energy costs are assumed to be only $4.00 per day; and she thinks she should be making $10 per hour for her time. Viewing this from a total (multifactor) productivity perspective, what is her productivity at present and with the new paint?
In-Class Problems from the Lecture Guide Practice Problems Problem 4: How would total (multifactor) productivity change if using the new paint raised Ms. French’s material costs by $0.50 per doll?
