Question 380
An IS auditor evaluates this situation: An audit team changes sampling procedures each quarter without documenting why results are no longer comparable. Which audit principle MOST directly applies to this situation?
- Audit quality programs should evaluate consistency, methodology and continuous improvement.
- Auditor objectivity is impaired by assessing one's own recent design work.
- Follow-up must evaluate whether remediation controls are effectively implemented, not just promised.
- Remediation after the audit period does not retroactively prove the control operated during that period.
Explanation
Correct Answer
A:Audit quality programs should evaluate consistency, methodology and continuous improvement. The corresponding audit procedure is: Compare past and current sampling standards, review findings and documentation quality.
Incorrect Answers
B:Auditor objectivity is impaired by assessing one's own recent design work.
