JIT (Just-In-Time) is a manufacturing approach that focuses on producing items only when they're needed, reducing storage costs and waste. Think of it like a restaurant that buys fresh ingredients only when customers order, rather than storing large amounts that might go bad. In automotive manufacturing, this means parts arrive at the assembly line exactly when they're needed, instead of taking up warehouse space. Companies like Toyota made this system famous, and now many manufacturers use it to save money and work more efficiently. You might also hear it called "lean manufacturing" or "Toyota Production System."
