Literally, "just" in time would mean "not more (material, goods,...) than needed" in time, wouldn't it? A real world analogy to Kanban.

- kqr 4y agoKanban is indeed one way to do just in time. It's useful primarily for the more variable flows. For more regular flows, you can often rely on the average flow rate working out and schedule deliveries in advance.
- marcosdumay 4y agoJIT is mostly a name for inter-companies Kanban (the factory version of Kanban, not the software one). And because of that, yes, the amount of inventory is pretty much arbitrary.
- kqr 4y agoThis is a common misconception. People often talk about the kanban style JIT because it looks impressive, in some sense. There's all these things going back and forth. But as Taiichi Ohno himself would tell you: if it looks impressive, it's wasteful. It's a lot of motion with little movement. Efficiency looks disappointingly obvious and simple. Kanban is a necessary evil when you have been unsuccessful in driving out variation, it's not a desirable state of things.
