In a parallel conversion strategy, what is unique about the new and old systems?

• A. It is tested by an outsourced company
• B. It replaces the old one at an appointed time
• C. They run together
• D. It is introduced in stages

Answer: (C)

In a parallel conversion strategy, the distinct characteristic is that both the new and old systems operate simultaneously during a transitional period. This approach allows users to run both systems in parallel, enabling them to compare outputs, verify that the new system works as intended, and ensure continuity in business operations. By having both systems in operation, any discrepancies can be identified and addressed before fully migrating to the new system. This reduces the risk of failures that could arise from switching to a new system without adequate testing and validation. While other options describe different aspects of system conversions, they do not capture the essence of the parallel conversion method. For instance, introducing a system in stages is indicative of a phased or incremental conversion approach rather than parallel operation. Similarly, replacing the old system at a specific time pertains more to a direct cutover method rather than a parallel strategy, which emphasizes simultaneous functionality. Testing by an outsourced company may enhance reliability but does not define the operational characteristics of parallel conversion itself.
