What type of Kanban is used when one container of parts is to be moved to a production line or supermarket?

The correct choice is based on the concept of a Withdrawal Kanban, which specifically signals when to retrieve a certain quantity of parts from a storage area to a production line or supermarket. This type of Kanban acts as a fluid communication tool within a lean manufacturing environment, promoting a just-in-time approach where parts are brought to the production area only as they are needed.

In this scenario, the use of a single container of parts clearly aligns with the purpose of a Withdrawal Kanban, which indicates that when an item is taken from a stock location, it needs to be replenished. This not only streamlines inventory processes but also minimizes waste by ensuring that only the necessary items are available at any time.

The other options represent different types of Kanban systems that serve various functions. One-card Kanban generally refers to a simplified version where only one signaling card is used for all transactions, while Two-card Kanban involves both a withdrawal and a production card to manage different processes. Kanban Square, often a visual tool for organizing work or parts, doesn't specifically refer to an inventory movement but rather to a designated area for workflow management. These distinctions clarify why the Withdrawal Kanban is the most appropriate choice in this context.
