  1. 1 Introduction to Production and Operations Management

  2. Learning Objectives • Define the term operations management • Basics of “Value Addition” • Compare and contrast service and manufacturing operations • Basics of “Goods-Services Continuum” • Describe the operations function and the nature of the operations manager’s job • Describe the key aspects of operations management decision making

  3. Operations Management • Managing that part of the organization responsible for producing goods and services • Management of systems or processes that create goods and/or provide services

  4. The Organization The Three Basic Functions Competitiveness?

  5. Value-Added Process The operations function involves the conversion of inputs into outputs Value-added = Value or price of outputs – Cost of inputs

  6. Value added Inputs Outputs Transformation/ Land Goods Conversion Labor Services process Capital Feedback Control Feedback Feedback Value-Added Process The operations function involves the conversion of inputs into outputs

  7. Food Processor Hospital Process

  8. Value-Added & Product Packages • Value-added is the difference between the cost of inputs and the value or price of outputs. • Product packages are a combination of goods and services. • Product packages can make a company more competitive.

  9. Tangible Act Goods-service Continuum Goods Service Surgery, teaching Song writing, software development Computer repair, restaurant meal Smart phones: Product/Service? Automobile Repair, fast food Home remodeling, retail sales Automobile assembly, steel making Product packages = Good(s) + service(s) Make a company more competitive- more value to customers

  10. Production of Goods vs. Delivery of Services • Production of goods – tangible output, production oriented • Delivery of services – an act • Service job categories • Government • Wholesale/retail • Financial services • Healthcare • Personal services • Business services • Education

  11. Goods vs Service: Key Differences

  12. Challenges of Managing Services • Service jobs are often less structured than manufacturing jobs • Customer contact is higher • Worker skill levels are lower • Services hire many low-skill, entry-level workers • Employee turnover is higher • Input variability is higher • Service performance can be affected by worker’s personal factors

  13. Scope of Operations Management • Operations Management includes: • Forecasting • Capacity planning • Scheduling • Managing inventories • Assuring quality • Motivating employees • Deciding where to locate facilities • Supply chain management • And more . . .

  14. Key Decisions of Operations Managers • What What resources/what amounts • When Needed/scheduled/ordered • Where Work to be done • How Designed • Who To do the work

  15. System operation – personnel System Design – inventory – scheduling – capacity – project – location management – arrangement of departments – quality assurance – product and service planning – acquisition and placement of equipment Decision Making

  16. Operations Management Decision Making • Models • Quantitative approaches • Analysis of trade-offs • Systems approach • Establishing priorities • Ethics

  17. Physical (Crash tests) – – Schematic (Blueprints) – Mathematical, statistical Models A model is an abstraction of reality. Typically a simplified version Tradeoffs What are the pros and cons of models?

  18. Models Are Beneficial • Easy to use, less expensive • Require users to organize • Increase understanding of the problem • Enable “what if” questions • Consistent tool for evaluation and standardized format • Power of mathematics

  19. Limitations of Models • Quantitative information may be emphasized over qualitative • Models may be incorrectly applied and results misinterpreted • Nonqualified users may not comprehend the rules on how to use the model • Use of models does not guarantee good decisions

  20. Quantitative Approaches • Linear programming • Queuing Techniques • Inventory models • Project models • Statistical models

  21. Analysis of Trade-Offs • Decision on the amount of inventory to stock • Increased cost of holding inventory Vs. • Level of customer service

  22. Suboptimization Systems Approach “The whole is greater than the sum of the parts.”

  23. Trends in Business • Major trends • The Internet, e-commerce, e-business • Management technology • Globalization • Management of supply chains • Outsourcing • Agility • Ethical behavior

  24. Other Important Trends • Ethical behavior • Operations strategy • Working with fewer resources • Revenue management • Process analysis and improvement • Increased regulation and product liability • Lean production • Combination of Mass Production (high volume, low unit cost) and Craft Production (variety and Flexibility)
