description
Limiting work in progress (WIP) is a concept widely popularized by Kanban, but in different forms it also exists in other agile approaches. Despite that, applying limits is a practice which many teams find either counterintuitive or non-value adding and eventually skip it. We should however start with answering a couple of basic questions. Why do we introduce limits in the first place? What do we get thanks to them? After all we don’t apply limits just to make our work less convenient, do we? The session will discuss limiting work in progress revealing a bit of mechanics of the concept and pointing false beliefs which we often embrace in software development teams. It will show how this mechanics can be exploited to improve our processes in both expected and unexpected ways. After the session you should be tempted to apply WIP limits in your process or, if they are already a part of the process, to adjust them accordingly. And most of all, you should know why and how limits are working, which will help you to make a decision when you should introduce them and how strictly a team should respect them.
