alt Hacker News> "WIP" does not work
Such a bold statement when you must know that countless people have a very different experience. Kanban the team methodology is about process efficiency and avoiding bottlenecks.
WIP limits are triggers to redirect resources to the bottleneck is that causes the pileup. Example: If there is pileup of PRs needing review, that is the trigger for devs on the team to stop making new PRs and switch to doing reviews.
Kanban is certainly not the best methodology for all team tasks but where it fits it works very well.
Sadly, for a lot of teams "we are doing kanban" means nothing more than "we are using a task board with columns" or worse "we have no constraints or flow controls and do everything ad hoc."
Yes, many people disagree with me. Take this as an assumption that I'm checking in my service. Of course, it is necessary to limit the amount of work, but in my opinion, WIP per column does not work. Therefore, I have implemented limits only for the entire kanban board (process).
