OPSM elective course: Operations Strategy Operations & the Process View: What is a Process? Information structure Inputs Process Management Network of Activities and Buffers Outputs Goods Services Flow units (customers, data, material, cash, etc.) Labor & Capital Resources Organization Chart Process customer customer suppliers What is Operations Management? Management of business processes How to structure the processes and manage resources to develop the appropriate capabilities to convert inputs to outputs. – What is appropriate? What defines a “good process”? Performance: Financial Measures Absolute measures: – revenues, costs, operating income, net income T Ct t – Net Present Value (NPV) = 1 r t 0 Relative measures: – ROI, ROE EBIT Tax – ROA = Average Total Assets Survival measure: – cash flow Firms compete on product attributes. This requires process capabilities. Price (Cost) P Quality Q – Customer service – Product quality “order winners” Time T – Rapid, reliable delivery – New product development Variety V – Degree of customization To deliver we need “capabilities” Fit between Strategy and Processes Processes must fit the operations strategy of the firm: Competing on -Cost (Southwest Airlines) -Quality (Toyota,Arçelik) -Flexibility (HP) -Speed (McDonalds) all require different process designs and different measures to focus on. Corporate StrategyKey Performance Indicators Operations StrategyProcess Design& Improvement Performance Measures Performance Objective Some typical Measures Cost Minimum delivery time/average delivery time, utilization of resources, labor productivity, added value, efficiency, cost per operation hour Quality Number of defects per unit, level of customer complaints, scrap level, mean time between failures, customer satisfaction scores Speed Customer query time, Order lead time, frequency of delivery, actual versus theoretical throughput time, cycle time Flexibility Time needed to develop new products/services, range of products/services, machine change-over time, average batch size, time to increase activity rate, average capacity/maximum capacity, time to change schedules Linking the strategic role & process view: Strategic Operational Audit Existing Desired Feasible Business Strategies Strategy Gap?

Customized cakes? – What are the different set-ups in each process? Classification Scheme for Manufacturing Systems Organizing production processes: Around the product or process? Discrete Part Manufacturing – Job Shops – Batch Production – Mass Production Continuous Processes A Spectrum of Production Processes Part Variety Job Shop Batch Prod. Mass Prod. (Flow Line) Contin Flow Proce ss Part Quantity Fit of Process, Volume, and Variety (from Ch. 7) Repetitive Process (Modular) Low-Volume (Intermittent) High Variety One or few units per run, high variety (allows customization) Changes in modules Modest runs, standardized modules Changes in attributes (such as grade, quality, size, thickness, etc.) Long runs only Process focus projects, job shops,(machine, print, carpentry) Standard Register Poor strategy Repetitive (autos, motorcycles) Harley Davidson High-Volume (Continuous) Mass Customization (difficult to achieve, but huge rewards) Dell Computer Co.
