What metrics should explain
Backlog is not only a count. It is the lived result of queues, incomplete packets, correction loops, missing service/proof, slotting pressure, staff burden, and unclear readiness.
Useful public measures
First touch
How long received work waits before initial review.
Deficiency turnaround
How long correction loops take from return to resolution.
Queue age
How old unresolved work is across operational lanes.
Packet readiness
How much work is ready for review versus blocked by missing steps.
Public reporting boundary
Public reporting should use aggregate measurements and public-safe explanations. It should not expose private case details, protected records, or personally sensitive material.
