Exam CISA topic 1 question 592 discussion

When transaction processing times increase after a major release, the most likely cause is a change in system performance due to factors like increased load, resource bottlenecks, or inefficient use of system resources. The capacity management plan outlines the system's expected performance, resource usage, and how it scales to handle transaction loads. It also defines the thresholds for system capacity and provides guidelines on how to manage increased workloads.

If the transaction processing time of an order processing system increases, it may be due to a lack of system capacity. A capacity management plan is a plan for evaluating the load that the system can handle, the size of transactions, resource utilization, etc. By checking whether this plan is properly formulated, it becomes clear how to respond when the load on the system increases and how to increase resources if necessary.

Stress testing is designed to evaluate how a system behaves under extreme conditions, including high transaction volumes or loads. If the transaction processing times have increased, reviewing the stress testing results can help identify whether the system was adequately tested under conditions that simulate the production environment. Stress testing assesses how well the system can handle peak loads, and it helps identify potential performance bottlenecks or issues that may arise during heavy usage. By reviewing the stress testing results, the auditor can gain insights into the system's performance characteristics and identify any weaknesses or areas that need improvement, which could be contributing to the increased transaction processing times.

B: Stress testing results, this related to performance testing.
