High WIP on the municipal transit fare-system ART correlates with long flow time, yet leaders keep starting fare-cap features and ignore the Little’s Law-style connection. What should the RTE make visible?

Short Explanation
A packed subway car does not get downtown faster because more people squeezed in. Same idea: more in-process fare work usually means longer waits. Empty a few seats—cut WIP—and the ride shortens.
Full Explanation
Little’s Law relates WIP, throughput, and flow time: for a given completion rate, more items in process means longer time in process. The municipal transit fare-system ART cannot go faster by starting more work. The RTE should connect WIP reduction to shorter flow time and coach the train to finish in-flight fare items before launching more.
