A kanban card is used to signal that:
A. The next work center is stopped
B. A materials handler has run out of parts
C. A machine has broken down
D. Parts are needed by a work center E.
The correct answer and explanation is :
The correct answer is D. Parts are needed by a work center.
A Kanban card is a visual signal used in Lean manufacturing and Just-in-Time (JIT) systems to manage inventory and workflow. It helps to trigger the movement or replenishment of materials between work centers or from suppliers. In this case, the Kanban card is used to signal that parts are needed by a work center. Here’s a breakdown of how it works and why option D is correct:
Explanation:
Kanban is a Japanese term meaning “visual signal” or “card.” It is part of a pull-based inventory control system, which aims to reduce waste, optimize inventory levels, and streamline production processes. The Kanban card typically moves with the materials throughout the manufacturing process. When a work center or production stage needs more parts, the Kanban card is sent to the previous stage in the process, signaling that more parts are required.
The primary function of a Kanban card is to ensure that production continues smoothly without excess inventory or downtime. When a work center has used up the parts or materials, the Kanban card is sent back to the supplier or previous work center to trigger the replenishment of materials. This pull-based system ensures that materials are delivered only when needed, thus minimizing waste and reducing costs.
Why the other answers are incorrect:
- A. The next work center is stopped: A Kanban card does not directly signal a halt in production, but rather a need for replenishment or materials.
- B. A materials handler has run out of parts: While this is a valid issue, the Kanban card specifically signals the need for more parts at a work center, not necessarily that a handler has run out.
- C. A machine has broken down: A Kanban card does not address machine malfunctions. It is used for material flow and inventory control.
