JIT, or Just-in-Time Production, is an inventory and production planning system that seeks to deliver the required goods or services at the exact time they are needed. By aiming for zero inventories and responding quickly to consumer demand, JIT Production enables businesses to reduce costs, improve efficiency, and respond rapidly to customer needs. The efficient use of time and resources results in a dramatic improvement in overall efficiency. When done correctly, JIT Production benefits both the company and its customers.
