Manufacturing Strategy Ken Homa
Manufacturing Strategy • Capacity • Level • Deployment • Centralization • Vertical integration • Scope / focus
Capacity • Aggregate level • Deployment • By product & part • By process • By geography
Capacity Utilization • Target 85-90% utilization • Long-run : • Prudently add anticipatory capacity : within existing facitliies, then new • Avoid adding costly “last chunk” • Short-run : • Use excess capacity to build inventory for high demand periods • Add overtiime to boost capacity when req’d Can run > 100% for brief periods • Focus on bottlenecks (CCRs)

Manufacturing Strategy • Centralized • Leverages fixed costs & investment • Consistent quality contol • Simplified supply chain • Decentralized • Closer to market • More manageable Scale determines range of affordable options
Where on The Continuum ? Assembly Only Vertically Integrated Vertical Integration
Raw Material Parts Components Sub-assemblies Modules Final Assemblies
Vertical Integration Drivers • Availablity • Scale economies • Learning curve • Control
Factory Orientation • Broad line factories • Scale & scope economies • Flexible capacity • Focused factories • Narrow product scope • Common parts & processes • Often “full products” • “Plants within plants”
