What is a Just In Time (JIT) System?

• A. Just In Time System - Inputs are only ordered when they are needed
• B. A system where stocks are maintained at all times
• C. A marketing strategy to increase demand
• D. A system for long-term supplier contracts

Answer: (A)

A Just In Time system is about getting materials and inputs exactly when they are needed in the production process, not keeping large quantities stored. By ordering and receiving inputs only as they’re required, a business cuts down on inventory, lowers storage costs, and improves cash flow. It relies on precise scheduling and reliable suppliers to avoid delays, since there’s little buffer stock.

This aligns with the idea of a pull system—production is driven by actual demand rather than pushing stock through regardless of need. The other descriptions don’t fit because keeping stocks at all times means high inventory, which JIT seeks to minimize; using marketing to boost demand is about generating demand, not timing of inputs; and long-term supplier contracts are about procurement arrangements, not the core timing and inventory philosophy of JIT.
