What does the Dual-Card Kanban System combine?

The Dual-Card Kanban System effectively combines Conveyance Kanban and Production Kanban to streamline production processes in lean manufacturing environments. In this system, two distinct cards are used: one for signaling the need to move a batch of materials (Conveyance Kanban) and the other for signaling the need to produce a batch of products (Production Kanban).

This dual approach helps in managing the flow of materials as well as the production processes by ensuring that materials move efficiently to where they are needed while also maintaining a smooth production cycle. The integration of both types of Kanban enhances visibility throughout the supply chain and allows for a more responsive production system, reducing waste and improving overall efficiency. By clearly distinguishing between the need for transportation and the need for manufacturing, the system enables organizations to optimize operations and respond promptly to customer demand.
