Performance/Investigation
Investigate Metric Slip
Guided attribution workflow — five steps, one accountability decision.
- Step 1: Select metric
- Step 2: Decompose timeline
- Step 3: Matched cohorts
- Step 4: Test indicators
- Step 5: Assign ownership
STEP 1
Select the slipping metric
Current
34.2 hours
Target
24 hours
Previous 30 days
27.8 hours
Variance
+6.4 hours
STEP 2
Decompose the service timeline
Queue
+1.1h
Triage
+0.4h
Diagnosis
+0.8h
OEM Decision
+2.7h
Parts Wait
+2.1h
Repair
-0.3h
Validation
-0.4h
The largest increases (OEM Decision +2.7h, Parts Wait +2.1h) are outside physical repair execution.
STEP 3
Compare matched cohorts
Same faultSame vehicle configSame mileage rangeSame procedureSame time period
Prime Service
38.4h
Alpha Fleet Repair
31.8h
Nexus Authorized Service
32.6h
Fleet-wide increase across all partners: +5.9 hours
Partner variation exists, but the metric is deteriorating across all partners, indicating a broader product-support constraint.
STEP 4
Test partner versus product indicators
- Same fault across multiple vehicles Yes
- Same fault across multiple partners Yes
- Repair procedure followed Yes
- Partner repair execution within target Yes
- OEM decision SLA missed Yes
- Replacement part unavailable Yes
- Repeat failure after correct repair Yes
- Incomplete diagnostic evidence No
- Workmanship failure No
