Certified Information Systems Auditor (CISA) — Question 429

Management has requested a post-implementation review of a newly implemented purchasing package to determine to what extent business requirements are being met. Which of the following is MOST likely to be assessed?

Answer options

• A. Implementation methodology
• B. Test results
• C. Purchasing guidelines and policies
• D. Results of live processing

Correct answer: D

Explanation

The results of live processing are crucial for assessing the effectiveness of the purchasing package in real-world scenarios, as they provide insight into how the system performs under actual conditions. While implementation methodology, test results, and purchasing guidelines are important, they do not directly reflect the system's capacity to meet business needs after going live.
