IIA-CIA-Part2 Exam Dumps : Practice of Internal Auditing

To test the theory that shutdowns are occurring due to outdated purchasing requirements that have not been updated for changes in production techniques, the auditor should compare the parts needed based on the most current production estimates and the revised materials requirements plan (MRP) with the purchase orders generated from the system. This comparison will help identify discrepancies between what is needed and what is being ordered, highlighting whether the system is failing to update purchasing requirements correctly. This method directly addresses the suspected cause of the shutdowns and provides clear evidence for or against the auditor’s theory.

A. The decision affects the test procedures performed:Correct. The choice between statistical and nonstatistical sampling affects the design of the sample selection, execution of audit procedures, and the nature of conclusions drawn. Statistical sampling involves probabilistic techniques that influence sample size and evaluation, whereas nonstatistical sampling relies on auditor judgment.

B. The auditor's response to errors detected will be influenced:While error response is critical, it is influenced more by the nature and materiality of the errors than by the sampling approach.

C. The competence of the evidence obtained is greater with statistical sampling:This is incorrect because the competence of evidence depends on the procedure itself, not the sampling method used. Both methods can yield competent evidence if applied correctly.

D. Nonstatistical sampling may be more cost effective:While this can sometimes be true, it is context-dependent and not universally applicable, so it is not the best answer.

Domain II: Risk Management and Control – Sampling Techniques and Audit Evidence.

Comprehensive and Detailed Explanation:

Risk-and-control questionnaires are structured tools used to quickly determine whether specific control activities are formally in place. They are efficient (D) because they provide management’s input on whether defined controls exist, helping auditors identify gaps before fieldwork. However, they are not the most effective way to understand processes (C) since questionnaires rely on management’s responses, which may be biased or incomplete. Instead, walkthroughs and direct observation provide more depth. Options A and B are incorrect since questionnaires are efficient and do not prevent team involvement. Therefore, the correct view is that such questionnaires are an efficient tool for confirming control existence, not for complete process understanding.
