Quick answer
Handling QA sampling needs a supported browser/app, enough disk/memory and a valid input file. Sample for risk, channel and people, not just the most recent tickets.
Why it matters
Missing any condition can turn an environment issue into a false file-corruption diagnosis.
Stratify by channel × issue × severity × agent.
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
- Stratify by channel × issue × severity × agent.
- Review 100% of high-risk tickets.
- Check monthly whether the sample covers the long tail.
