Define the decision before the scorecard
One scorecard should not simultaneously decide carrier replacement, daily exception handling, and contract renewal. Write down the decision, observation window, and decision owner first. Otherwise, a temporary fluctuation can be mistaken for a structural problem.
Use the multi-carrier strategy overview to define which routing decision the measurement supports. The carrier performance scorecard helps turn comparable tracking and billing records into an ongoing review.
| Decision | Evidence needed | Do not infer directly |
|---|---|---|
| Operational investigation | A repeatable gap within a lane or exception type | Immediate network-wide volume reduction |
| Contract negotiation | Trend, billing, and root-cause records under stable definitions | Replacing contract terms with one composite score |
| Volume reallocation | Comparable cohorts, sufficient observations, backup capacity, and rollback plan | Routing every shipment to the historical winner |
