JIT (Just-In-Time) is a business strategy for managing inventory and production where materials arrive exactly when needed, rather than being stored for long periods. Think of it like a restaurant that buys fresh ingredients daily instead of storing weeks worth of food. Companies use JIT to reduce storage costs, minimize waste, and keep operations efficient. This approach is particularly popular in manufacturing and warehousing. You might also see it called "lean inventory management" or "Toyota Production System" since Toyota made it famous. While the concept started in manufacturing, it's now used in many industries including retail and healthcare.
