What is meant by 'Kanban' in a JIT environment?

In a Just-In-Time (JIT) environment, 'Kanban' refers to a scheduling system that is crucial for facilitating lean and JIT production processes. The term itself originates from Japanese and translates to "visual signal" or "card." In this context, Kanban serves as a visual management tool that helps organizations control inventory levels and production flow by signaling when it is time to produce more items or restock materials.

Using Kanban, production is closely aligned with demand, minimizing waste and excess inventory. This approach enables teams to maintain efficient workflows, adapt to changes in demand quickly, and ensure that resources are utilized optimally. By focusing on the visual aspects of production scheduling, Kanban promotes transparency and allows workers to see at a glance what needs to be done next, streamlining processes and enhancing overall productivity in a JIT environment.
