Just-in-Time (JIT) is a manufacturing strategy that minimizes wasted time and resources by providing products or services as they are needed. JIT requires the use of cellular manufacturing, or the sequential and staged manufacturing of a product. The aim is to minimize total production time by avoiding the batch and queue assembly process. Load leveling, process sequencing and Kanban are all essential elements of an effective JIT process.
Kanban is the inventory cue’s way of signaling when the next stage in the process is ready to receive the product from the previous stage, creating a “pull system.” This process minimizes inventory and overproduction waste by only purchasing resources as needed.
