There are ten important problems that Kanban helps to solve:
Visualize the workflow for all participants after splitting processes in parts. With the help of kanban boards the stations of a process can be visualized. Each board has a specific capacity. Therefore only a specific number of task can be done simultaneously. The tasks, features, user and stories of a process can be written on a kanban card. A single card is moving between the different kanban boards. This creates a pull-system, where a station picks up work from another station.
Every member of a kanban process can measure queue times, cycle times and throughput in ordert o organize workload at the stations nearly perfect.
There are six generally accepted rules for kanban:
1. Downstream processes may only withdraw items in the precise amounts specified on the kanban.
2. Upstream processes may only send items downstream in the precise amounts and sequencesspecified by the kanban.
3. No items are made or moved without a kanban.
4. A kanban must accompany each item at all times.
5. Defects and incorrect amounts are never sent to the next downstream process.
6. The number of kanbans should be monitored carefully to reveal problems and opportunities for improvement.
