Which concept emphasizes delivering materials exactly when needed to minimize inventory?

• A. Just-in-time (JIT)
• B. Quick Response
• C. ECR
• D. TPS

Answer: (A)

Delivering materials exactly when needed to minimize inventory is Just-in-time. This approach pulls materials into the production process only as they’re required, so stock sits for as little time as possible and work-in-process shrinks. When a part is consumed, a signal triggers its replenishment, keeping inventories lean and reducing carrying costs, obsolescence, and waste. For Just-in-time to work well, you need reliable suppliers, stable demand, small lot sizes, quick setup times, and an effective signaling system (like Kanban). It also means the supply chain is tightly synchronized with the production schedule, so any disruption can have amplified effects due to limited buffers. Quick Response focuses on rapid replenishment in consumer retail to minimize stockouts and markdowns; Efficient Consumer Response centers on collaboration across retailers and manufacturers to improve service levels and efficiency; the Toyota Production System is a broader framework that includes Just-in-time as a tool among other principles.
