Question 410
During a routine controls assessment at a regional hospital, the IS auditor learns that a migrated customer ledger total differs from the legacy system's validated closing balance. The affected operation supports patient-care scheduling and claims processing. Healthcare service continuity and protected records are at stake. Which audit procedure would provide the MOST DIRECT evidence about this control?
Explanation
Correct Answer
Correct. Reconcile source-to-target record counts and control totals; investigate rejected rows and test cutover and rollback. The procedure directly tests the reported condition that a migrated customer ledger total differs from the legacy system's validated closing balance. A defensible IS audit conclusion requires relevant and reliable evidence from the actual control population and period.
Incorrect Answers
Not the most direct fieldwork procedure for these facts. The relevant success criterion is evidence appropriate to the audit conclusion; this measures a different function.
Not the most direct fieldwork procedure for these facts. That result could pass without demonstrating evidence appropriate to the audit conclusion.
Not the most direct fieldwork procedure for these facts. Acceptance here depends on observing evidence appropriate to the audit conclusion, not only that test.
