CONWIP (Constant Work In Process)
Constant Work In Process
Pull system that limits total WIP in a production line and releases new work only when completed work exits.
Examples
- 01Under CONWIP, the line allows a maximum of 40 orders at once, and a new order is released only when a finished one leaves.
- 02At the gemba, the team checks that the CONWIP limit is respected and that no orders are started 'just to keep busy'.
- 03Introducing CONWIP cuts WIP by half, and lead time falls from 12 to 6 days without lowering output.
