Define control objectives, owners, frequency, evidence, dependencies, and tests that demonstrate intended outcomes.

Applicability & intent
Controls need a clear objective and mechanism. Design effectiveness asks whether the control could work; operating effectiveness asks whether it worked consistently during the period.
- Document why control design & effectiveness 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 |
|---|---|
| control narrative and process flow | Does governance establish accountable direction? |
| samples and operating evidence | Does the process operate consistently? |
| test procedure, exceptions, and conclusion | 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
- Distinguish preventive, detective, and corrective roles.
- Document population and sampling rationale.
- Link exceptions to risk and remediation.
