Impact on Purchasing and Supply
Whether a JIT production system works or not depends on how well purchasing does its job in selecting and managing suppliers.
Strategies:• A specific plan to reduce the number of supplier
utilized, using single and dual sources in many cases.
• Extensive use of long term contracting.
