Theory 110/Supply chain cycle/Progression phase
Progression Is Throughput Against WIP
The claim
Cycle time is set by the ratio of work in progress to throughput, so a chain can speed up by reducing WIP rather than by adding capacity.
01Mechanism
Little's law relates the quantities; the ratio sets the time.
02Prediction
Cycle time should track the ratio.
03Refutation
Time tracking capacity would remove WIP.
