Quick answer
If Calibration fails, try another file/format, unlock the file, reduce batch size, then update the tool/browser. Calibration fixes the problem of two managers scoring the same ticket differently.
Why it matters
Most failures are input/lock/resource issues, not the tool itself.
Use 5–10 samples, score independently before discussion.
Step by step
- Define QA goals and observable behaviors before building a giant scorecard.
- Stratify samples by shift, channel and risk so they represent real problems.
- Calibrate scoring boundaries before ranking or performance decisions.
- Attribute issues to knowledge, process, system or people before choosing fixes.
Common mistakes
- Scoring without calibration makes managers incomparable.
- Sampling only easy tickets biases the result.
- Using QA as punishment makes agents hide context.
- Looking only at CSAT while ignoring resolution and rework.
Checklist
- Scorecard has behavioral anchors.
- Sampling has stratification rules.
- Calibration records disputed samples.
- Issues have owners and review dates.
Key facts
- Use 5–10 samples, score independently before discussion.
- Resolve disputes against scorecard anchors, not persuasion.
- Update scorecard version and example library after calibration.
