Kanban is a Lean, continous workflow management and improvement process. Designed to reduce the idle time in a production process. The main idea behind the Kanban system is to deliver what the process needs exactly when it needs it.
In Japanese, the word "Kan" means "visual" and "ban" means "card," so Kanban refers to visual cards. Lean uses visual cards as a signaling system that triggers an action to supply the process with its needs either from an external supplier or from a warehouse.
- Kanban may aggregate team resources across functional area. This can un-intentionally create conflict.
