Which of the following is the PRIMARY purpose of performing a parallel run of a new system?
The primary purpose of performing a parallel run of a new system is to ensure that the new system produces the expected results. During a parallel run, both the old and new systems operate simultaneously, processing the same data and performing the same tasks. This allows for a direct comparison of their outputs to verify that the new system is functioning correctly and generating the correct results, which is crucial before fully transitioning to the new system.
D, because the question did not mention the old system meet the business requirement. Parallel run just make sure the new system can meet the functionality of old one, which is the expected result. What a trap question from ISACA.
D) To ensure the new system meets user requirements. The PRIMARY purpose of performing a parallel run of a new system is to **validate the operation of the new system against its predecessor**. During a parallel run, both the old and new systems operate simultaneously, processing the same data and performing the same tasks. This allows for a comparison of their outputs, which helps to ensure that the new system is working correctly. Therefore, the correct answer is **D. To verify the new system produces the expected results.
The primary purpose of performing a parallel run of a new system is to verify that the new system provides the required business functionality. A parallel run involves running both the existing (old) and new systems simultaneously for a certain period, and transactions are processed in both systems concurrently. During a parallel run, the organization can compare the output and results produced by the new system with the output and results of the existing system. The primary goal is to ensure that the new system meets the business requirements and performs the necessary functions as expected. This process helps identify any discrepancies, errors, or gaps in functionality.
Option A, "Ensure that the new system has the required business functionality," is a step to verify whether the new system meets the business requirements, but it is different from the main purpose of parallel execution. Verification of business functionality is usually done through testing and validation, which is done in the early stages of system development. Therefore, the main purpose of parallel execution of a new system is to verify that the system produces the expected results in the actual production environment.

During a parallel run, the organization can compare the output and results produced by the new system with the output and results of the existing system. The primary goal is to ensure that the new system meets the business requirements
While both options A and D are closely related, the primary purpose of a parallel run is to ensure that the new system provides the required business functionality. This includes verifying that the system produces the expected results, but it extends beyond just the output – it encompasses the overall functionality and performance in a real-world operational context. So, to provide a more accurate emphasis on the comprehensive evaluation of the new system's capabilities, the preference is for: A. To verify the new system provides required business functionality.
