Quick answer
Little’s Law: WIP = throughput × cycle time — the math behind WIP limits: to finish faster, start less; it turns ‘work harder’ advice into ‘start less’ arithmetic.
The law
Average WIP = average throughput × average cycle time — three variables, fixed relation.

In projects
Double the WIP at same throughput → double the cycle time — the queue is the problem, not the effort.
The applications
Why WIP limits shorten delivery; why long backlogs mean long waits; why ‘everything urgent’ delivers nothing.
Using it
Measure cycle time and throughput → predict lead time; cut WIP to cut wait — arithmetic, not motivation.
Bottom line
Little’s Law: WIP = throughput × cycle time — the math behind WIP limits: to finish faster, start less; it turns ‘work harder’ advice into ‘start less’ arithmetic.
