Which JIT tactic moves materials from the receiving dock directly to the assembly line without entering stockroom?

Back-flushing is an inventory management method that updates inventory levels automatically after production processes are completed, rather than tracking items at each stage. It does not involve the direct movement of materials from the receiving dock to the assembly line, as it is focused on the reconciliation of inventory post-manufacturing.

The Kanban pull system is a scheduling system that helps manage production and inventory levels by signaling when more materials are needed. While it aids in streamlining production, it does not describe the physical movement of materials from the receiving dock directly to the assembly line but rather focuses on managing inventory levels within the system.

The Andon system is a visual management tool used in manufacturing to signal issues or the need for assistance on the production line. It enhances communication about production status but does not pertain to the logistics of moving materials from the receiving dock to the assembly line.
