OPS.8:2 - Problem

Local limits can hide unfinished Work beyond a board boundary. Conversely, removing every visible queue can eliminate the ready supply that protects a costly or time-critical activity. Starting more items may increase incomplete kits while the activity needed for completion still lacks usable inputs.

The operation therefore needs to coordinate release, readiness, ordering and protection together, while preserving the distinction between a customer’s waiting time and the waiting visible at one service station.
