A practical research protocol for calibrating call quality reviewers around evidence, policy, accessibility, privacy, and escalation decisions.
Headline finding
Calibration improves consistency only when reviewers discuss the same evidence and policy definitions. Agreement without a shared rubric can hide a common mistake.
Methodology
Give reviewers the same de-identified sample, rubric, source notes, and escalation rules. Compare field-level decisions, resolve disagreements with the workflow owner, and version the rubric. Do not publish an agreement rate without sample and denominator details.
Key stats and takeaways
- Calibrate on fields, not personality or accent.
- Keep policy failures separate from coaching opportunities.
- Record unresolved rubric questions as governance work.
Review model
Check intent capture, required fields, read-back, consent or preference, route, handoff, privacy, accessibility, and disposition. Reviewers should cite the evidence supporting each decision and avoid inferring unstated facts.
Measurement table
| Measure | Definition | Review question |
| --- | --- | --- |
| Field agreement | Reviewers reach same decision per rubric field | Which field causes drift? |
| Evidence citation | Decision points to an observable record | Can another reviewer reproduce it? |
| Escalation agreement | Sensitive cases receive same treatment | Is policy unambiguous? |
| Rubric defects | Questions requiring owner decision | What needs versioning? |
FAQ
### Is reviewer agreement the same as quality?
No. Reviewers can agree on an incorrect or incomplete rubric.
### Who resolves a policy dispute?
The named workflow owner, with specialist review where required.
