The kanban system was originally developed to realize Toyota’s just-in-time system. This method is intended to improve the efficiency of inventory management. Roughly speaking, there is a merit that we can reduce the waste of stock as much as possible by making only necessary things and delivering them.

Kanban = purchase order slip

Kanban is called a production instruction sheet and it is treated like a delivery slip. The operation of making a car is a division of labor system and there are many processes.

In the Kanban System, you receive “Kanban” from the person in charge of the previous process and process and produce the product.

Deliverables that have been completed are delivered to the downstream along with the kanban. The kanban here acts like a statement of delivery as described above. When you have completed sending your own operation kanbans to the downstream operation, return the kanbans you received from the previous operation to the assignee of the previous operation. This repetition is the basis of the Kanban System.

In this sequence, we can minimize inventory.

This series of methods was later studied and systematized by a professor at MIT, and became widely known as “lean production system”.

Project Management Kanban System

For example, I will explain the Kanban System used in projects such as software development.

Imagine putting a paper balloon on the whiteboard.

Time flows from left to right. The 3 most minimums are [ToDo], [Doing] and [Done].

Write the above three steps on the whiteboard.

Then you write down the tasks you need to complete the project in Sticky Notes.

At first, put all the notes you wrote on [ToDo].

This time, the priority is determined among the sticky notes collected in [ToDo]. Move the high priority message to [Doing] to complete the task. Move to [Done] when you are done.

As you can see, the sequence of tasks completed from left to right is managed as a kanban for a project. The above is the simplest pattern, but it can be customized depending on the project, such as [Approve] flow or [Confirm] flow.

Advantages of the kanban system

The benefit of the Kanban System is “Visualization of the project”. You can see at a glance which tasks are in what state, and if you look at them as a whole, whether they are progressing or stagnating.
