Operations Flexibility Flex’i*bil’i*ty: capable and adaptable to change. • Perspective of the producer: Flexibility • Perspective of the customer: Responsiveness
Factors Driving Flexibility Shorter Product Life-Cycles Fragmented Markets Demand Uncertainty Increased New Product Intro’s Unexpected Competitors MarketplaceFactors Need for FLEXIBILITY OperationsFactors Pressures to Reduce Inventories Pressures to Improve Quality Process/Product Simplification Changing Supplier Relationships Smaller Plants/Facilities
Types of Flexibility • Mix Flexibility • Ability to produce a variety of products (goods/services) with the same operational processes. • Changeover Flexibility • Ability to rapidly change over equipment and technology for a variety of products • Modification Flexibility • Ability to implement rapid design changes; customize standard products to meet customer requirement
Types of Flexibility • Volume Flexibility • Ability to adapt quickly and easily to changing demand patterns and volumes • Rerouting/Program Flexibility • Ability to create products and add value in using alternative methods, routings, techniques. • Resource Flexibility • Ability to handle variations in input resources (e.g., raw materials) and to use alternative resources
Pitfalls of Flexibility • Focus vs. flexibility • Specialists vs. generalists • Cost/flexibility trade-offs • Flexibility for whom and what? • When does the market reward flexibility? • Customization/responsiveness squeeze
Inducing Flexibility • Alter design of operations (process) • single vs. multiple steps • focused layouts • general purpose equipment • assemble to order (vs. make to order/stock) • Alter design of product • design for manufacturability • shared parts and components • personnel with broad training • information technology to assist • cross-functional design teams • Manage demand • improved forecasts • yield management
Inducing Flexibility • Manage supply • alter purchase contracts for quick delivery • bring long lead-time items in-house • process in smaller batches • Use slack resources • yield management (induce demand) • multi-tasking of employees/personnel • Operate to forecast • improve forecast • determine service level • staff / produce to meet service level • hold intermediate stock / supplies
