Data Quality
Data Quality Assurance
Data quality assurance is the ongoing process of detecting errors, validating critical fields, and improving accuracy over time.
Allocator relevance: QA is how you avoid “wrong person” outreach and mandate mistakes that break trust with allocators.
Expanded Definition
QA includes automated checks (format, domain validity, duplication detection) and evidence-based review for high-impact fields (decision authority, roles, contacts). It also includes user feedback loops: correction requests are treated as signals to investigate and adjust evidence weighting.
Decision Authority & Governance
Governance defines QA thresholds, sampling rules, and escalation paths for disputed fields. QA must be auditable (what was checked, when, and what changed).
Common Misconceptions
- QA is a one-time cleanup.
- QA means “perfect data” (it means controlled error rates).
- QA can ignore freshness (stale data becomes wrong).
Key Takeaways
- QA is continuous and field-prioritized.
- Focus QA on actionability fields first.
- Tie QA to audit trail and correction workflows.
