So far I’ve not seen any discussion here of the role of “kaizen boxes” in kanban (production card) pull manufacturing. They’re a simple way to control batch size and hence limit work in progress to just what’s needed. Rather simplified that is, if you can see the kanban on the factory floor go and get a matching box. Make exactly the number of parts needed to fill every slot in the box. No more, no less. Then place the box over the kanban. Don’t make anything of this type again until someone has removed the box and you next see the kanban again. That can be expanded so that the tools needed to make the part are kept with the empty part container reducing the need to search for them when required.
