How this is calculated
Little’s Law: WIP = Throughput × Cycle Time. With 5 people at 70% focus, we estimate ~0.9 items finished per day. Multiplied by your 4-day cycle, that gives a total in-flight cap of 4, or roughly 2 per active column (To Do, In Progress, Review).
Rule of thumb: WIP ≤ team size × 1.5 prevents multitasking overload.
