What should an auditor do if a supervisor weakens a supported finding?

Start with the workpapers, not the personalities. Ask what evidence, criteria, rating methodology, or new facts support the revised finding. If the supervisor has a valid basis, document the change and update the conclusion. If the change is unsupported, preserve the original evidence and ask for the rationale through the engagement review process.

If the concern remains unresolved, escalate through the approved internal audit chain, such as the engagement manager, CAE, methodology owner, or quality review process. The goal is not to embarrass the supervisor. The goal is to keep final communication consistent with the evidence.

For CIA purposes, a rating should not be changed merely because management pushes back. It should change because the audit evidence and criteria support a different conclusion.
