Which inventory-management approach ensures supplies arrive just when needed?

• A. Just-in-time (JIT)
• B. Quick Response
• C. Continuous Flow Production
• D. Line Flow Production

Answer: (A)

Just-in-time inventory management focuses on delivering materials exactly when they are needed in the production process, not earlier. It uses a pull system where a part is consumed and signals trigger a prompt replenishment from suppliers. This tight synchronization with the production schedule minimizes on-hand inventory, reduces carrying costs, and cuts waste. Achieving JIT relies on reliable suppliers, frequent small deliveries, and clean, predictable demand, so that parts arrive in time to keep the line moving without piling up excess stock. Quick Response aims to speed replenishment to meet consumer demand and prevent stockouts, particularly in fashion or consumer goods, but it isn’t primarily about matching each arrival to the exact moment it is needed on the production floor. Continuous Flow Production and Line Flow Production are about the layout and pace of manufacturing processes themselves, not about coordinating the timing of material arrivals with production use.
