Applicability & intent
Privacy engineering translates policy into schemas, access paths, retention jobs, interfaces, telemetry, and tests. Retention must address copies, backups, derived data, and legal holds.
- Document why privacy by design & retention applies, what is in scope, and who is accountable.
- Translate obligations into owned, testable outcomes with proportionate evidence.
- Track exceptions, residual risk, changes, and corrective actions through governance review.
Governance lifecycle
- 01
Confirm scope, context, interested parties, legal or contractual basis, and authoritative sources.
- 02
Identify desired outcomes, owners, dependencies, existing controls, and evidence sources.
- 03
Assess design and operating effectiveness using representative, time-bound evidence.
- 04
Record gaps, risk, interim protections, target dates, and approval decisions.
- 05
Verify remediation, report residual risk, and schedule reassessment when context changes.
Evidence & assurance
| Evidence family | Assurance question |
|---|---|
| data flow and purpose map | Does governance establish accountable direction? |
| retention schedule and deletion design | Does the process operate consistently? |
| privacy tests and deletion evidence | Can the claimed outcome be independently verified? |
Evidence should be attributable, current, protected, reproducible, and linked to an accountable owner. A document alone does not demonstrate that a control operates effectively.
Readiness decisions
- Set privacy-protective defaults.
- Avoid logging sensitive fields without need.
- Test deletion across replicas and downstream systems.
