OPS.15:5.1 - Forty requests produce two different service measures

In this constructed case, all forty uncancelled requests in the selected cohort have reached their due dates. At the observation cutoff, twenty-seven finished on time, three finished late and ten remain open. The local service objective concerns timely completion of this due-date cohort and is 90%.

Observation or calculation	Value	Supported meaning
Requests completed by the cutoff	27 + 3 = 30	Thirty members of the cohort have a completion event.
On-time proportion among completed requests	27 / 30 = 90%	Ninety percent of the completed members finished on time.
On-time proportion among all requests due	27 / 40 = 67.5%	The cohort received timely service on twenty-seven of its forty requests.
Still-open requests whose deadlines passed	10	These members have already missed the timely-service condition.

The corrected account says that the due-date cohort missed its 90% objective. It retains the completed-only measure where someone actually needs that narrower description. The ten open requests remain visible for recovery and the recipients’ current service decisions.

A later completion of an overdue request changes its open/closed state but cannot make its original completion timely. If the parties revise a future commitment, preserve the original deadline where the historical comparison needs it. New requests with future deadlines belong to a separately defined current-work view, so they do not silently dilute this cohort’s result.

Use the existing service method to handle the overdue work and affected commitments. The account supports the missed-objective claim. It does not identify why the service failed or prove that a proposed staffing change will fix it.
