Operations Management Across the Organization

• OM is central because it produces goods and services, but it is one of three core functions:

  • Marketing/Sales: communicates offerings and generates demand; must understand OM capabilities and constraints.

  • Product/Service Development: creates new or modified offerings; must align with operational feasibility.

  • Operations: fulfills customer requests via production and delivery.

• Support functions enabling OM:

  • Accounting and Finance: cost data, investments, capital decisions; requires understanding of OM needs.

  • Human Resources: staffing, training, labor costs; must understand job requirements.

  • Information Systems (IS): enables data flow, forecasts, quality, inventory, scheduling; OM depends on IS and IS must leverage latest tech to support OM.

• Engineering and other disciplines contribute to product design and production capabilities; cross-functional coordination with suppliers and retailers across the supply chain is essential for success.

Creation of Goods and Services (Summary of Key Stages and Outputs)

• Goods and services are produced by transforming inputs to outputs; outputs can be consumer, industrial, or producer goods, or services.

• Key stages (Figure 3 reference): Design and Development, Procurement of Inputs, Transformation, Quality Control, Distribution and Delivery, Customer Interaction, Feedback and Improvement.

• Production vs. Service characteristics recap:

  • Goods: tangible, consistent definition, can be inventoried, lower customer interaction, capital intensive, longer lead times, objective quality.
