my name is Mike and I am a Mark Anderson Community Member.
In this video, I will explain to you the relation between the Kanban System and the Pull System.
Then, I will explain the 8 rules of Kanban.
As many authors state, I would like to remind that:
“A pull system is one in which work is released on the status of the system and thereby places an inherent limit on Work in Progress”
On the other hand:
“A push system is one in which work is released without consideration of the system status and hence does not inherently limit Work in Progress”
Remember that the “pull” is a principle and the Kanban is a way to reach the “pull”.
it should be clear that an MRP system is closer to a push system and the Kanban is one method of pull.
▶ Pull System Explained
The main advantages of a pull system are:
Reduced Work In Progress
Reduced Lead Time
Smoother Production Flow
If you look at the video on Lean Principles, you will see that the pull is the fourth of the steps cited by Womack and Jones in the book Lean Thinking.
Hence, do not start a Kanban Implementation before implementing the previous three steps.
The Kanban System is an effective way to reduce Muda (Waste), Mura (Unevenness), and Muri (Overburden).
▶ The 8 Rules Of Kanban
There are 8 Rules to follow to implement a Kanban System.
1. Downstream Operations come to withdraw parts from upstream operations.
2. Make only the exact quantity indicated on the Kanban.
3. Demands are placed on upstream operations by means of cards or other signals.
4. Only active parts are allowed at the workplace. Active Parts should have specific locations.
5. Authorisation to produce is by card (or signal) only.
6. Each Kanban card circulates between a particular pair of workstations only.
7. Quality at the source is a requirement. Only good items are sent downstream.
8. The number of Kanbans should be reduced as problems decrease.
In the next video, I will explain to you the different types of Kanban.
