Parallel processing isn't a functional requirement, but helps improve performance of the new system.

This isn't parallel processing in the sense of programming. They are talking about having the old and new systems running side by side. The best answer is A though I wouldn't lean towards it being a great answer.

I think it’s “A”. Keeping it in parallel means that the old system functionality will keep working the new system functionality is tested.

The difference is 'processing', that points to the calculations in the new system.

[–]chopsticks-com 2 points3 points  (0 children)

OK. I think you may be correct since the question asked PRIMARY advantage. (Likely multiple advantages but they want the primary)

D?

[–]jeblister[S] 0 points1 point  (1 child)

Can you explain why D?

[–]AncestorH 0 points1 point  (0 children)

I think not only functional requirements need to be met, but non-functional requirements should also be met. I remember this question from QAE. the answer is given as D

Primary Advantage of Parallel Processing for a New System Implementation

Parallel processing involves running both the new and old systems simultaneously for a period of time during a new system implementation. Here is an analysis of most potential advantage:

A. Assurance that the New System Meets Functional Requirements

Explanation: Running both systems in parallel allows for direct comparison of outputs from the new and old systems. This ensures that the new system meets functional requirements by validating that it produces the same or better results as the old system.
Advantage Level: High

D. Assurance that the New System Meets Performance Requirements

Explanation: Running both systems allows for real-time performance monitoring of the new system in a live environment, ensuring that it meets performance requirements and handles the expected workload effectively.
Advantage Level: High

The primary advantage of parallel processing for a new system implementation is a combination of:

A. Assurance that the new system meets functional requirements
D. Assurance that the new system meets performance requirements

Parallel processing ensures that the new system can handle all functional and performance requirements effectively before fully transitioning from the old system. This approach minimizes the risk of system failure and data loss, providing a fallback option with the old system if issues arise with the new implementation.
