The most appropriate course of action for the CAE when facing a lack of internal audit staff with necessary skills to audit a high-risk area, like the engineering department, is to supplement the internal audit team with external experts who possess the required competencies. This approach ensures that the audit can be conducted effectively and comprehensively, allowing for an accurate assessment of risks and controls in the engineering department without delaying the review until new auditors can be hired and trained.

Institute of Internal Auditors (IIA) - International Professional Practices Framework (IPPF)QUESTION NO: 453

Which of the following process weaknesses is most likely to cause an internal auditor the most concern about fraud risk?

A. Final employee payroll list is belatedly sent to the bank for payment processing.

B. Employee salary is calculated by the payroll system without further verification.

C. Employee personal records in the permanent file are not updated in a timely manner

D. Employee personal information in the payroll system could be updated without approval.

Answer: D

The scenario where employee personal information in the payroll system could be updated without approval presents a significant concern for fraud risk. This lack of control creates an opportunity for unauthorized changes to employee information, potentially leading to fraudulent activity such as ghost employee schemes or unauthorized salary alterations. Such a control weakness directly impacts the integrity of payroll transactions and should be a primary concern for internal auditors.References: Institute of Internal Auditors (IIA) - International Professional Practices Framework (IPPF)
