**Target operating model — recommended contracts, not installed collection.** All owner and cadence entries below are proposals to confirm before the pilot, not assigned responsibilities or approved schedules.
|
|
|
|
**Unimplemented metric — no live telemetry.** This is a prospective contract, not an implemented calculation or collector.

|
Mean elapsed time from production deployment failure onset to service restoration, with median/p90 and unresolved count/age.

|
| Numerator | Sum of recovery_at minus failure_started_at in hours for recovered eligible deployment failures |
|
|
| Denominator | Count of recovered eligible deployment failures with valid timestamps |
|
|
| Expression | N / D |
|
|
| Aggregation | mean |
|
|
| Unit | hours/failure |
|
|
| Eligible population | Production deployment failures beginning in window; latest verified restoration if a recovery is rescinded. |
|
|
| Exclusions | Nondeployment incidents; invalid timestamp pairs reported missing, not treated as instantaneous recovery. |
|
|
| Events and source | deployment.failed; service.restored; incident service |
|
|
| Owner / cadence | Platform & IT / Weekly with unresolved failures |
|
|
| Missing evidence | Unresolved failures reported separately and excluded only from recovered-duration distribution; prevent declaring improvement without their visibility. |
|
|
| Gaming and limits | Premature recovery declarations or omit hard cases; require operational readback and carry unresolved ages. Descriptive signal, not causal AI productivity attribution. Source completeness, task mix and sampling limit inference; report uncertainty. Not all-incident MTTR; recovered-only sample has survivorship bias. p90 nearest rank. |
