The document discusses key concepts in operations management including defining OM, distinguishing between goods and services, and explaining productivity and its measurement. It covers the critical decisions OM managers make, trends in the field, and strategies to improve productivity, noting that productivity increases are needed for economic growth. Labor, capital, and management each contribute to about 10%, 38%, and 52% of annual productivity gains respectively.

1. Operations Management Session 1 – Operations and Productivity

4. 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

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

29. New Trends in OM Figure 1.6 Local or national focus Reliable worldwide communication and transportation networks Global focus, moving production offshore Batch (large) shipments Short product life cycles and cost of capital put pressure on reducing inventory Just-in-time performance Low-bid purchasing Supply chain competition requires that suppliers be engaged in a focus on the end customer Supply chain partners, collaboration, alliances, outsourcing Past Causes Future

30. New Trends in OM Figure 1.6 Lengthy product development Shorter life cycles, Internet, rapid international communication, computer-aided design, and international collaboration Rapid product development, alliances, collaborative designs Standardized products Affluence and worldwide markets; increasingly flexible production processes Mass customization with added emphasis on quality Job specialization Changing socioculture milieu; increasingly a knowledge and information society Empowered employees, teams, and lean production Past Causes Future

31. New Trends in OM Figure 1.6 Low-cost focus Environmental issues, ISO 14000, increasing disposal costs Environmentally sensitive production, green manufacturing, recycled materials, remanufacturing Ethics not at forefront Businesses operate more openly; public and global review of ethics; opposition to child labor, bribery, pollution High ethical standards and social responsibility expected Past Causes Future

33. 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

34. The Economic System Figure 1.7 Feedback loop Outputs Goods and services Processes 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%). Inputs Labor, capital, management

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.
