Just-In-Time

Just-in-Time (JIT) is a inventory and production management philosophy originating in Japan — most notably Toyota — that aims to produce or procure goods only when they are needed, in the exact quantities required. By synchronizing supply with demand, JIT minimizes inventory holding costs, reduces waste, and improves operational efficiency. It relies on strong supplier relationships, reliable forecasting, and streamlined processes. When executed effectively, JIT decreases overhead, shortens lead times, and increases overall organizational responsiveness.
