  1. 1. OPSM 901: Operations Management Session 1: The Process View Process Positioning Strategic Fit Ko ç Un iversity Graduate School of Business E MBA Program Zeynep Aksin zaksin @ku.edu.tr
  2. 2. Key Principle of course: 1. The Strategic Role of Ops <ul><li>“ A company’s operations function is </li></ul><ul><li>either a competitive weapon </li></ul><ul><li>or </li></ul><ul><li>a corporate millstone . </li></ul><ul><li>It is seldom neutral.” [ Skinner ‘69 ] </li></ul>
  3. 3. Operations as a Competitive Weapon <ul><li>Dell Computers </li></ul><ul><li>Innovative Supply Chain Strategy (direct model) </li></ul><ul><li>Southwest Airlines </li></ul><ul><li> L eader in lowfare flights, by elimination of all waste </li></ul><ul><li>Zara </li></ul><ul><li>More on this later today.. </li></ul><ul><li>Vestel Durable Goods </li></ul><ul><li>Distribution optimization leads to increased customer satisfaction as well as lower costs </li></ul>
  4. 4. Key Principle of Course: 2. The Process View of Ops UL Sup. WH WH Sub. WH KA Ind. Markets Groceries Markets . . . Sana KA: 64 days Groceries:132 days Shelf life: 120 days! 76 days collection time Sales cost: 4% Trade rebate: 12% Logistics: complex 1997: 35000/76000 tons Sana and Aymar collected
  5. 5. Consumer centric-efficient SC UL Distributors Groceries Market KA Consumer Sana KA: 2 weeks 36 days collection time Warehouse stock level 12% -  8% Sales cost: 6% Trade rebate: 5.2% Logistics: simple 120000-140000/180000 outlets Make-to-order
  6. 6. Operations & the Process View: What is a Process? Inputs Outputs Goods Services Labor & Capital Information structure Network of Activities and Buffers Flow units (customers, data, material, cash, etc.) Resources Process Management
  7. 7. Organization Chart
  8. 8. Process customer customer suppliers
  9. 9. Life is a process.. <ul><li>Projects: one time processes </li></ul><ul><li>Eating lunch at the cafeteria </li></ul><ul><li>EMBA program </li></ul><ul><li>Your career </li></ul><ul><li>Your life </li></ul>
  10. 10. What is Operations Management? <ul><li>Management of business processes </li></ul><ul><li>How to structure the processes and manage resources to develop the appropriate capabilities to convert inputs to outputs. </li></ul><ul><ul><li>What is appropriate ? </li></ul></ul>
  11. 11. All Managers are Operations Managers <ul><li>All managers must transform inputs into outputs </li></ul><ul><li>Example: Accounting Manager </li></ul><ul><ul><li>Inputs : data, information, labor </li></ul></ul><ul><ul><li>Transformation : application of accounting principles and knowledge </li></ul></ul><ul><ul><li>Outputs : accounting reports, knowledge of performance, ... </li></ul></ul><ul><li>All managers have an “operation” to run </li></ul>
  12. 12. What defines a “good process”? Performance: Financial Measures <ul><li>Absolute measures: </li></ul><ul><ul><li>revenues, costs, operating income, net income </li></ul></ul><ul><ul><li>Net Present Value (NPV) = </li></ul></ul><ul><li>Relative measures: </li></ul><ul><ul><li>ROI, ROE </li></ul></ul><ul><ul><li>ROA = </li></ul></ul><ul><li>Survival measure: </li></ul><ul><ul><li>cash flow </li></ul></ul>
  13. 13. Performance Measurement <ul><li>Basing performance measurement only on financial ratios may be deceiving in that it does not capture continuous improvement and innovation </li></ul><ul><li>The Balanced Score Card (BSC) s ystem was developed by R. Kaplan ve D. Norton in 1992 ( HBS 1,1992 .) </li></ul><ul><li>The objective is to give managers measurements that reflect both financial and operational performance in a balanced way </li></ul>
  14. 14. Balanced Score Card (BSC) <ul><li>BSC, complements financial measures with </li></ul><ul><ul><li>Customer satisfaction </li></ul></ul><ul><ul><li>Process </li></ul></ul><ul><ul><ul><li>Throughput times </li></ul></ul></ul><ul><ul><ul><li>Defect rates, etc. </li></ul></ul></ul><ul><ul><li>Learning and development </li></ul></ul><ul><li>related measures that help to reflect future financial success </li></ul>
  15. 15. BSC Vision and Strate gy Finan cial Customer Processes Learning and Development How should our shareholders view us so that we can claim financial success Which processes should we perfect to be seen as successful by our customers and shareholders How can we sustain learning and development to adhere to our vision How should customers view us so that we attain our vision Objective Measurements Targets Initiatives
  16. 16. Firms compete on product attributes. This requires process capabilities. <ul><li>Price (Cost) P </li></ul><ul><li>Quality Q </li></ul><ul><ul><li>Customer service </li></ul></ul><ul><ul><li>Product quality </li></ul></ul><ul><li>Time T </li></ul><ul><ul><li>Rapid, reliable delivery </li></ul></ul><ul><ul><li>New product development </li></ul></ul><ul><li>Variety V </li></ul><ul><ul><li>Degree of customization </li></ul></ul>“ order winners” To deliver we need “capabilities”
  17. 17. Performance Measures Time needed to develop new products/services, range of products/services, machine change-over time, average batch siz e , time to increase activity rate, average capacity/maximum capacity, time to change schedules Flexibility Customer query time, Order lead time, frequency of delivery, actual versus theoretical throughput time, cycle time Speed Number of defects per unit, level of customer complaints, scrap level, mean time between failures, customer satisfaction scores Quality Minimum delivery time/average delivery time, utilization of resources, labor productivity, added value, efficiency, cost per operation hour Cost Some typical Measures Performance Objective
  18. 18. Process Capabilities are affected by Process Structure and Management <ul><li>Process structure or architecture: </li></ul><ul><ul><li>(1) inputs and outputs </li></ul></ul><ul><ul><li>(2) flow unit (“jobs”) </li></ul></ul><ul><ul><li>(3) network of activities & buffers </li></ul></ul><ul><ul><ul><li>quantity & location </li></ul></ul></ul><ul><ul><ul><li>precedence relationships </li></ul></ul></ul><ul><ul><li>(4) resource allocation </li></ul></ul><ul><ul><ul><li>capacity & throughput </li></ul></ul></ul><ul><ul><li>(5) information structure </li></ul></ul><ul><li>Operations Planning & Control </li></ul><ul><li>Organization </li></ul>
  19. 19. Fit between Strategy and Processes <ul><li>Processes must fit the operations strategy of the firm: </li></ul><ul><li>Competing on </li></ul><ul><ul><li>- Cost (Southwest Airlines) </li></ul></ul><ul><ul><li>-Quality (Toyota) </li></ul></ul><ul><ul><li>-Flexibility (HP) </li></ul></ul><ul><ul><li>-Speed (McDonalds) </li></ul></ul><ul><li>all require different process designs and different </li></ul><ul><li>measures to focus on. </li></ul><ul><li>Corporate Strategy  Key Performance Indicators </li></ul><ul><li> Operations Strategy  Process Design& Improvement </li></ul>
