Key Measures: Total dollars; period-by-period unit value changes; ratio of sales to working capital?

    • Characteristics of JIT Purchasing—
      • Purchase in small lots with frequent deliveries
      • Mutual, consistent improvement by the buyer and supplier
      • Collaborative efforts between buyer and supplier
      • Efficient point-to-point communication linkages
      • The “rights”--
        • right quantity
        • right time
        • right quality
  • Differences between JIT & Traditional Purchasing JIT Purchasing Smaller lot sizes More frequent deliveries No rejection from the supplier Long-term contracts Buyer decides delivery schedule Innovation encouraged Minimal paper work Less formal communication Traditional Relatively large lot sizes Less deliveries at higher quantities 2% rejection from supplier Lowest price is main objective Time consuming, formal paperwork Formal communication
