Certified Information Systems Auditor (CISA) — Question 253

Which of the following methods will BEST reduce the risk associated with the transition to a new system using technologies that are not compatible with the old system?

Answer options

• A. Pilot operation
• B. Parallel changeover
• C. Modular changeover
• D. Phased operation

Correct answer: A

Explanation

The correct answer is A, as a pilot operation allows for testing the new system in a controlled environment before full deployment, thereby minimizing risks. Options B, C, and D increase the complexity and potential for issues during the transition and do not provide the same level of risk mitigation as a pilot operation.
