In a Lean context, what does "Just-In-Time" (JIT) mean?

In a Lean context, "Just-In-Time" (JIT) refers to the practice of producing and delivering products or components exactly when they are needed in the production process. This approach minimizes inventory levels, which, in turn, reduces waste and enhances efficiency. By producing items only as they are required, organizations can ensure that resources are not tied up in excess inventory, allowing for more flexibility and responsiveness to customer demand.

This principle is fundamental to Lean manufacturing as it aligns production closely with customer demand, significantly reducing the costs associated with holding and storing large quantities of inventory. It promotes a flow where each step in a production process occurs smoothly and without delay, fostering a more streamlined operation. Implementing JIT can lead to better quality control, faster turnaround times, and the ability to quickly adapt to changes in consumer preferences.
