In my last few posts I have shown you different ways to establish pull systems, and which one is right for you. This post discusses how you can mix and combine these systems. You can combine some pull systems within the same pull loop, although there are some restrictions. Combinations of different kanban systems are very common, often also including a CONWIP system.
You can also combine different pull systems for sequential loop, where for example a kanban system feeds into a CONWIP system. This blog post is loosely based on chapter 3.3 and 11.1.7 of my new book All About Pull Production: Designing, Implementing, and Maintaining Kanban, CONWIP, and other Pull Systems in Lean Production.
This is a cross post with the same article on Planet Lean.
