Fleet pilots drown in dashboards. NADIR shadow pilots commit to one measurable outcome: MTTFF-RE — mean time to first flag on repair events. If you cannot detect elevated residuals within seven days of glass or body work on at least seventy percent of eligible ROs, the pilot failed — regardless of how polished the UI looked in week one.
Definition
For each repair event with a known RO close timestamp and sufficient telematics coverage, MTTFF-RE is the elapsed time until the first CRITICAL (or agreed CAUTION+) tier transition attributable to post-repair scoring. Events with no flag within the observation window count against the SLA. Events without telemetry coverage are excluded explicitly in the readout appendix — not silently dropped.
Why fleets care
Maintenance leaders do not need another health score. They need to know which vehicles returned from shop with latent miscalibration before those vehicles accumulate miles, near-misses, or insurer questions. MTTFF-RE ties detection latency directly to repair-network accountability and internal QA — in days, not quarters.
Risk and legal teams get a single Exhibit A chart for pilot closeout instead of a binder of anecdotal screenshots.
Target for a 4-week shadow pilot
- Population: 50–150 ADAS-equipped VINs with mixed repair types (glass, front-end, mirror)
- Mode: Shadow only — queue and evidence exports, no ECU writes
- SLA: MTTFF-RE ≤ 7 days on ≥ 70% of covered repair events
- Deliverable: Signed evidence samples + weekly digest + week-4 MTTFF-RE chart
How it appears in Console
Operators see CRITICAL rows keyed to VIN and repair context. Executives see cohort curves: time-from-RO to first flag, stratified by shop and procedure type. Developers pull the same cohort via API for internal QA systems. The product walkthrough episode on analytics shows the fixture data end-to-end.
What MTTFF-RE is not
It is not a replacement for OEM calibration procedures, ASIL validation, or physical bay work. It is not a correction guarantee. NADIR advisory analytics surface candidates for human review; they do not command brakes, steering, or ECU parameter writes.
