A utility company is implementing a new billing system. The cutover plan includes a parallel run, where both the old and new systems operate simultaneously for one month. The IS auditor is evaluating the plan. What is the most important consideration for the parallel run?

The old system should be decommissioned immediately after the parallel run begins.

The results from both systems must be compared and reconciled to ensure the new system produces accurate billing.

The parallel run should be shortened to reduce costs.

The parallel run should be conducted only in a test environment.

A company implemented a new human resources (HR) system six months ago. The post-implementation review reveals that the system is not being used by managers for performance reviews, and they continue to use spreadsheets. What is the most likely reason for this?

The system may not meet the managers' needs or may be too difficult to use, indicating a gap between design and actual requirements.

The system is technically flawed and should be decommissioned.

The managers were not trained on the system, so they avoid it.

The post-implementation review was conducted too early.

What is the primary purpose of User Acceptance Testing (UAT)?

To ensure that all modules work together correctly.

To identify and fix defects in the system code.

To verify that the system meets the business requirements and is acceptable to end users.

To test the system's performance under peak load conditions.

A company implemented a new procurement system nine months ago. The post-implementation review shows that the system is meeting its performance objectives, but the user satisfaction survey indicates that the procurement team finds the system difficult to use. The project sponsor asks the IS auditor for a recommendation. What is the most appropriate action?

Conduct a root-cause analysis to understand the usability issues and develop a corrective action plan.

Recommend that the system be replaced with a different product.

Decommission the system and return to the legacy system.

Ignore the user feedback because the system is meeting performance objectives.

Who is typically responsible for executing User Acceptance Testing (UAT)?
