Often when WIP limits are introduced we miss the point of them being the driver for further process improvement, but rather focus on what our WIP limit should be, or how we are going visualize it on our board. So I often share a story on how that can work.

Imagine that you are working at a lean car factory. Your job is to mount the doors. The cars arrive in a steady stream down the line and you mount doors from a pallet that get to your station. The pallet has 10 doors on it and you pick a door at time to mount onto the card using an awesome looking robotic arm.

Most likely, I was not there, the station in question was starved for new work. This happens on a visualized board when one or more columns in a row have no stickies in them. Meaning that if the downstream processes need more work they have no more (prioritized) work to pull.

The trick with WIP is that you want to balance it to a point where the process is flowing smoothly. Relating back to the previous story, this is not an end state but just a stepping stone to greater process improvements.

The other day I saw a board for about 4-5 people with 2 stickies on it, the column before at the end of the process. There were about 4 columns before those stickies. Meaning that there will be quite some time before new work reach this point.

Is this good or bad? That cannot be deduced from this (and my) knowledge, but I would rather agrue that this is a point where more WIP is needed to flow more work faster through the process.

If WIP is too low - workers will be idle. Then you will hear comments like "I have nothing to do after this". This is not bad in itself, since we now have slack that we can use for improvements, collaboration or lower priority work. If it happens all the time you should consider increase the WIP.

A common refrain is that certain endeavors—such as large-scale ERP implementations—are incompatible with lean and agile methodologies. To this, I offer a simple yet profound response: "Not yet." Rather than accepting the status quo, we must challenge it, seeking innovative solutions guided by lean principles.
