Traditional Kanban is a visual signaling system initiated within the Toyota Production System (TPS), aimed at optimizing production efficiency by responding directly to actual demand rather than forecasts.

Unlike push systems that often lead to overproduction, pull-based production relies on signals, such as Kanban cards or empty bins, to trigger work only when needed.

The emergence of Kanban in post-World War II Japan was primarily inspired by the supermarket model, wherein stock is replenished based on customer purchases, making it more efficient in resource utilization.

Kanban cards serve two purposes: a production Kanban, which authorizes the creation of goods, and a withdrawal Kanban, which permits the transfer of finished goods to the next stage of production.

This approach reduces waste by ensuring that only necessary items are produced, thus minimizing excess inventory and associated costs.

Principles like Just-in-Time (JIT) ensure that production aligns with real-time demand, allowing for high responsiveness and flexibility in operations.

By integrating Kanban practices into various sectors—including manufacturing and service industries—organizations can implement waste reduction strategies effectively, promoting a culture of continuous improvement.

Implementing Traditional Kanban requires mapping processes and establishing links between activities, ensuring that upstream processes only commence when downstream signals indicate a need.
