Peak backlog root cause signal brief
Operational signals that show whether a peak-season backlog came from labor coverage, workflow design, or outbound cutoff pressure.
Claim
Peak backlog recovery works better when the first broken baseline is recorded before the team layers on emergency fixes.
Queue acceleration point: Before or after cutoff
The moment the queue starts accelerating shows whether the bottleneck formed upstream or only after outbound windows closed.
Recovered throughput delta: After first intervention
If throughput barely improves after added labor, the main constraint is probably process flow or cutoff timing instead.
Operational implication
Teams should record the first measurable backlog signal before applying emergency recovery so the next surge plan improves instead of repeating the same blind spot.
