Guide to Understanding Work-in-Progress (WIP) Limits in Kanban Methodology
What is WIP Limit?
WIP stands for Work in Progress. In the context of Agile Project Management and Kanban methodology, WIP limits restrict the maximum amount of work items in the different stages of the workflow. The primary goal of a WIP limit is to ensure that a team doesn’t start and commit to too much work at once.
Why it is Important?
WIP limits encourage balance, prioritize focused work, help team to identify inefficiencies, and reduce context shifting. This approach minimizes the waste of semi-done work and maximizes the flow of productive and value-creating efforts.
How it works?
In practice, if a limit has been hit for a certain phase in the workflow, team members cannot move more tasks into that phase. They must first complete (and move) some of the current work items before taking on new ones. This approach helps ensure that work doesn’t pile up in any single phase of the process, keeping things flowing smoothly.
