The purpose of developing a kanban flow diagram is to help the kanban kaizen team better visualize what the new process will actually look like and where, in the factory work area, key attributes of the kanban pull system will be physically placed. As such, the diagram should be drawn approximately to scale. It will also help in the process of generating the action items list necessary for the team members to "Go-Do." One technique in creating the kanban flow diagram is to create it on flip chart size paper using Post-its to represent the key attributes.

The process for developing a kanban flow diagram is as follows:

1. Illustrate the supplying and consuming process.

2. Illustrate the kanban board position in the workplace.

3. Illustrate the supermarket position in the workplace.

4. Illustrate the milk run path and frequency.
