WIP limit

A work-in-progress (WIP) limit caps how many items the team can have in flight at once, per workflow stage. WIP limits force teams to finish work before starting new work — the central practice of Kanban. Without them, work piles up in 'in progress' states while nothing ships; with them, bottlenecks become immediately visible at the stage that's full.

Setting a WIP limit is more art than science — common starting points are team size × 1.5 for active work, or 2 per engineer. The right number is the one that makes the team uncomfortable but not paralysed: too low and people sit idle; too high and the limit doesn't change behaviour. Mid-sprint WIP-limit breaches are a signal worth investigating in retrospectives — they usually point to skipped acceptance criteria, blocked dependencies, or scope expansion mid-story.
