When planning for the implementation of a new system, an organization will opt for a parallel run PRIMARILY to:

When implementing a new system, an organization may opt for a parallel run to ensure the new system's effectiveness and minimize disruptions. A parallel run is a type of system testing that involves running both the old and new systems simultaneously for a period of time to compare their results.
The primary purpose of a parallel run is to validate system processing (option B). By running the old and new systems in parallel, the organization can compare the output and ensure that the new system is producing accurate results. This helps identify any errors or discrepancies that may have occurred during the implementation process.
Parallel runs also provide an opportunity to verify that system interfaces were implemented (option D). System interfaces are important in ensuring that different systems can communicate and exchange information seamlessly. Running the old and new systems simultaneously can help identify any issues or errors in the interfaces, allowing the organization to make necessary corrections.
While facilitating the training of new personnel (option C) is also a benefit of parallel runs, it is not the primary purpose. Parallel runs allow users to become familiar with the new system, but training should occur before the parallel run begins.
Finally, ensuring that the system meets required user response time (option A) is not the primary purpose of a parallel run. User response time is typically measured during system testing and performance tuning, which occurs before the parallel run.
In summary, an organization will opt for a parallel run primarily to validate system processing and verify that system interfaces were implemented.
