PROCESS SELECTION Chapter 4
Outline • Process Selection • Service Process Design • Choice of Technology • Process-Flow Analysis
Process Selection • Product-Flow Characteristics • Classification by Type of Customer Order • Process Selection Decisions • Product-Process Strategy • Mass-customization • Cross Functional Decision Making
Product-Flow Characteristics • Types of Product Flow • Line Flow • Batch Flow • Project Flow • Characteristics of Flows (see Table 4.1)
Line Flow WS 1 WS 2 WS 3 WS Task or work station Product flow
Batch Flow WS 2 WS 4 WS 3 WS 1 WS 5 WS Product flows Task or work station
Project Flow 2 4 Start End 1 3 Task Task or activity Precedence relationship
Classification by Type of Customer Order • Make to Stock (MTS) • Make to Order (MTO)
Make to Stock (MTS) • Advantages • Disadvantage • Key performance measures • Information flow (see Figure 4.4)
Make to Order (MTO) • Advantages • Disadvantage • Key performance measures • Information flow (see Figure 4.4)
Information-flow Comparison Make-to-Stock (Figure 4-4)
Information-flow Comparison Make-to-Order (Figure 4-4)
Process Selection Decisions • Process characteristics matrix • Factors affecting process choice
Factors Affecting Process Choice • Market conditions and competition • Capital requirements • Labor supply and cost • Management skills • Materials supply and cost • State of technology
Product-Process Strategy • Product-Process Matrix (see Figure 4-5) • Product Life Cycle (PLC) stages • Process Life Cycle stages • Modified Product-Process Matrix (see Figure 4-6) • Cross functional decision making and product-process strategy
Product Life Cycle Stages • Low volume-low standardization, one of a kind • Multiple products, low volume • Few major products, higher volume • High volume-high standardization, commodity product
Process Life Cycle Stages • Jumbled flow (job shop) • Disconnected line flow (batch) • Connected line flow (assembly line) • Continuous flow
