A signaling system (often with colored cards) based on consumption, which is set up to replace items only when the customer takes the previous item, creating a pull instead of push system.
In the diagram above, the process is controlled, so that parts move only when there is an open spot in the kanban to put your work. If no spot exists, then no work should be done, and the team should go help solve the problem that is preventing work from being done upstream.
One of the simpler approaches for kanban is called a 2-bin system. One bin is in use, while the other bin is being replenished or refilled. This video below explains it in much detail« Back to Glossary Index
