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.

IIA Standard 2320 - Analysis and Evaluation

After management responds to audit findings and provides an action plan, it is crucial for the internal audit activity to follow up to validate that the promised changes have been implemented and are effective. This follow-up ensures that the issues identified, such as those related to segregation of duties in accounts payable, have been appropriately addressed.

IIA Standard 2500 – Monitoring Progress:

This standard requires the internal audit activity to monitor the implementation of management’s corrective actions. Following up on audit findings is essential to ensure that the actions taken effectively mitigate the identified risks.

Validation of Corrective Actions:

By conducting a follow-up review, the internal audit activity can verify that the changes have been made as planned and assess whether these changes are sufficient to resolve the issues. This process helps maintain the integrity and effectiveness of the internal audit function.

IIA Practice Advisory 2500-1:

The advisory emphasizes the importance of follow-up activities to confirm that management’s responses to audit recommendations have been implemented as intended.

Option B (Include in the next scheduled audit): While this is a backup plan, it may delay the validation of corrective actions, allowing potential risks to persist.

Option C (No further action): This approach is inappropriate because it assumes the problem is resolved without verification, which could lead to unmitigated risks.

Option D (Placing an auditor in the department): This could compromise the independence of the internal audit function and is not a standard practice.

Detailed Explanation:Why Not Other Options?Conclusion: Option A is correct because it ensures that the internal audit activity fulfills its responsibility to validate that management’s corrective actions have been implemented and are effective, aligning with IIA standards on monitoring progress.

The flowchart indicates that different individuals are responsible for various stages of the bank reconciliation process. The Treasury Accountant posts payments and performs reconciliations, while the Senior Treasury Accountant obtains and uploads bank statements, and the Treasury Supervisor approves/reviews the reconciliations. This segregation of duties ensures that no single individual has control over all aspects of the financial transaction process, which helps in preventing errors and fraud.References:

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.
