Certified Information Systems Auditor (CISA) — Question 978

An organization has engaged a third party to implement an application to perform business-critical calculations. Which of the following is the MOST important process to help ensure the application provides accurate calculations?

Answer options

• A. Quality assurance (QA)
• B. Change management
• C. Key performance indicator (KPI) monitoring
• D. Configuration management

Correct answer: A

Explanation

Quality assurance (QA) is vital as it involves systematic testing to ensure the application performs accurately and meets specified requirements. While change management, KPI monitoring, and configuration management are important, they do not directly focus on verifying the correctness of calculations, which is the primary concern for business-critical applications.
