Kanban is a lean method, a framework to visualize work and improve the flow of value through the system.
Initiated by Toyota as part of the Toyota Production System, Kanban (in Japanese) is a visual card used as a scheduling system, showcasing the essential information and progress of the work through the product development system.
Following four essential practices help optimize the flow of value:
- Visualize the workflow
- Limit work in progress
- Manage flow
- Make process policies explicit
Through pull based movement of the work, Kanban helps achieve evolutionary improvements in process and product.
