Define eligibility before counting
Synthetic 100 received requests include 20 marked test and 10 cancelled before work starts. The local task-success measure excludes those 30. Of 70 eligible requests,63 succeed and 7 fail. Classification is fixed from the request evidence, not chosen after outcome.
| Class | Count | Included |
|---|---|---|
| Test | 20 | No |
| Pre-start cancelled | 10 | No |
| Eligible success | 63 | Yes |
| Eligible failure | 7 | Yes |
Reconcile exclusions and outcomes
- Apply stated exclusions
- Keep eligible failures in denominator
- Divide 63 by 70
Cancelling a request after failed work does not meet the supplied pre-start exclusion.
What is the agreed task-success ratio?
Show the worked answer
90%, 63/70. 63/100=63% answers a different received-request measure;63/63=100% hides the seven eligible failures.

| Case | Decision | Reason |
|---|---|---|
| Denominator 70 | Correct for local measure | Includes 7 failures |
| Denominator 63 | Reject | Removes eligible failures |
Export exclusion reasons beside counts so another reviewer can reproduce 70. State the measure name with 90%, not a general company reliability claim.
