What does just-in-time inventory aim to achieve in lean systems?

• A. Just-in-time inventory aims to minimize inventory and reduce waste by receiving goods only as needed.
• B. Just-in-time means keeping large safety stocks.
• C. Just-in-time is a method of rapid product development.
• D. Just-in-time is a marketing strategy to time product launches.

Answer: (B)

In lean systems, just-in-time inventory is about delivering materials precisely when they are needed to support production, so you keep as little inventory on hand as possible and reduce waste from excess stock, handling, and obsolescence. It relies on a pull approach—signals that trigger replenishment, close coordination with suppliers for frequent, small deliveries, and ongoing efforts to shorten changeovers and stabilize processes. This setup aims for smooth flow and rapid response, not accumulated buffers. The statement that describes keeping large safety stocks would run counter to JIT. Large buffers hide variability and raise carrying costs, storage needs, and potential obsolescence, whereas JIT targets minimal buffers and tighter control to reveal and address problems quickly. It’s also not about rapid product development or timing product launches in marketing; those are different objectives unrelated to inventory flow.
