Data Quality Management Guide

Define 'Good Data' Before You Profile or Buy a Tool

The four data quality dimensions that matter for compliance-critical records, each with a numeric threshold, field, and breach action.

"Data should be mostly accurate" is not a threshold

Vague targets are unenforceable and useless for reporting, yet most programs start profiling records or shortlisting tools before anyone has agreed what "good" means for each dataset. Without a shared, measurable definition, remediation efforts lack direction and audit evidence lacks credibility.

This guide sets the definition first: the four dimensions that matter for regulated records, each tied to a numeric threshold and a specific regulatory minimum, before any profiling or tooling work begins.

The four dimensions, thresholded

A worked threshold structure ties each dimension to a field, a numeric target, and a breach action.

COMPLETENESS

100%

Consent timestamp. Breach action: block processing. Assessed field-level, not record-level.

ACCURACY

95% verified

Postal address, matched against authoritative sources. Breach action: flag for review.

CONSISTENCY

100% match

Opt-out status, cross-system. Breach action: halt campaign sends.

TIMELINESS

24 months

Identity record last verified. Breach action: trigger re-verification.

What you can do once you've read it

Agree one measurable standard of 'good'

Give governance, legal, and operations a shared numeric definition for each dataset before a program starts, so remediation has direction and audit evidence holds up.

Tie each control to the article it satisfies

Map thresholds and workflows directly to GDPR 5(1)(d), 5(2), 7, 16, and 22, plus CCPA, FCRA, and the EU AI Act, instead of defending controls in the abstract.

Lift concrete examples into your own program

Adapt the threshold tables, remediation SLA tiers, KPI sets, and alert levels rather than inventing your own from scratch.

Buy tooling against the right requirements

Evaluate profiling, rules-engine, and lineage capabilities against the controls your regulatory environment actually imposes, before you assess features or pricing.

Grounded in the current rulebook

Every control in the guide maps to the framework it satisfies.

GDPR articles

Cites GDPR Articles 5(1)(d), 5(2), 7(1), 16, 22, 30, and 83(5).

US & sector law

References CCPA/CPRA (Civil Code 1798.106), FCRA, HIPAA (45 CFR 164.526), PSD2, and UK PECR.

AI frameworks

References the EU AI Act (Regulation 2024/1689, Article 10, Annex IV) and the NIST AI Risk Management Framework.

Enforcement case study

Analyzes the FTC's 2026 enforcement action against RentGrow as a failure-pattern case study.

Regulator guidance

Frequently asked questions

No. The numeric thresholds, SLA tiers, KPI sets, and alert settings are DataRidge-suggested examples to adapt to your own risk assessment, not regulatory requirements or industry standards. The regulatory obligations they map to are cited explicitly.
