Distinguish symptoms from causes in order to propose lasting improvements rather than one-off fixes.
- Criterion and gap — Compare the observed condition against the applicable criterion and measure the gap.
- Root cause — Trace the gap back to its organizational, technical or cultural cause.
- Effect and risk — Assess the potential impact and the residual risk to objectives.

Turn findings into realistic, proportionate, value-creating recommendations, accompanied by a formal management response.
- Recommendation options — Compare several possible treatments based on cost, timeline and impact.

- Implementation evidence — Verify the effectiveness of the action, not merely its reported completion.
- Closure and reporting — Validate closure and inform the audit committee of overdue actions.
