Certified Information Systems Auditor (CISA) — Question 182

Which of the following is the PRIMARY advantage of parallel processing for a new system implementation?

Answer options

• A. Assurance that the new system meets functional requirements
• B. Significant cost savings over other system implementation approaches
• C. More time for users to complete training for the new system
• D. Assurance that the new system meets performance requirements

Correct answer: A

Explanation

The primary advantage of parallel processing is that it allows for the new system to be tested alongside the old system, ensuring that it meets functional requirements before full deployment. While cost savings, training time, and performance assurance are important, they are not the primary focus of parallel processing as an implementation strategy.
