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?

  1. Audit quality programs should evaluate consistency, methodology and continuous improvement.
  2. Auditor objectivity is impaired by assessing one's own recent design work.
  3. Follow-up must evaluate whether remediation controls are effectively implemented, not just promised.
  4. 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.
