The rotational model refers to a staffing arrangement where employees, such as internal auditors, are rotated into different roles within the organization, often for a fixed period. In this scenario, a senior internal auditor is hired within the internal audit activity for two years before transitioning to an operations manager role. This model helps in developing a deeper understanding of the organization, broadening skill sets, and fostering cross-functional expertise. It benefits both the internal audit activity and the broader organization by facilitating knowledge transfer and career development.

IIA Standard 1210 – Proficiency: "Internal auditors must possess the knowledge, skills, and other competencies needed to perform their individual responsibilities."

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.

The most effective management action to prevent similar issues in the future involves both corrective and preventive measures. Coaching the IT specialist addresses the immediate knowledge gap and mistake that occurred. Introducing a secondary control, such as a review or verification step, ensures that future access requests are granted correctly, thereby preventing similar errors. This combination addresses the root cause and adds a layer of assurance. References:

Stratified sampling is used when the population can be divided into distinct subgroups (strata) that differ significantly from each other but are internally homogeneous. In the context of auditing, revenue earned through cash receipts or as receivables would have different characteristics and risk profiles. Stratifying the population allows the auditor to ensure that each subgroup is adequately represented in the sample, leading to more reliable and accurate audit conclusions.
