Why setting WIP limits can shorten Kanban cycle times for teams

A WIP limit caps how many tasks a team works on simultaneously, and new work is only started once something else is completed. The guide argues that this simple rule shapes priorities, ownership and who is empowered to decline new requests. A full board can feel productive, but spreading effort across many tasks tends to delay everything and leave little shipped. Drawing on Little's Law, the article illustrates how reducing parallel work lowers average cycle time without any increase in speed. It also stresses that a limit only works if the team genuinely stops starting new tasks and collaborates to finish existing ones when the limit is reached.
