Certified Information Systems Auditor (CISA) — Question 621

Which of the following is the MOST effective approach in assessing the quality of modifications made to financial software?

Answer options

• A. An independent auditor will be engaged to undertake a pre-implementation review.
• B. The quality of the implemented product will be assessed during acceptance testing.
• C. The quality plan will be assessed during the design phase of development.
• D. Independent quality assurance (QA) activities will be undertaken at various phases of the project.

Correct answer: D

Explanation

The correct answer is D because conducting independent QA activities throughout different stages of the project ensures ongoing quality assessment and mitigation of issues as they arise. Option A focuses only on a pre-implementation review, which may not capture all potential defects. Option B limits assessment to the acceptance testing phase, and Option C addresses the quality plan rather than the software quality itself.
