The queue that was about to miss
Harlow Utilities (illustrative)
Billing runs a 120-second service-level target, so the wait-time rule is armed at 90. Mid-morning it fires. The console has Billing at 108 seconds and climbing, while two rows down Deliveries is comfortably under target with four agents sitting idle.
Capacity moves across before the target is missed, rather than being explained the next morning in a meeting about why it was missed, and the rule that caught it stays on the board afterwards with the threshold it fired at still showing. Nobody has to reconstruct it.
