The CIA Exam (Part 2 - Practice of Internal Auditing) requires auditors to identify the root causes of issues and deviations from criteria, not just report symptoms. A root cause analysis seeks the underlying reason for a problem, rather than describing its occurrence.
* Option A simply describes the condition (missing results).
* Option B identifies a trend but not the underlying cause.
* Option D shifts responsibility to employees without addressing why results were not saved.
* Option C identifies a system design flaw that prevents employees from saving results, which is a true root cause.
Therefore, including Option C in the audit report demonstrates compliance with internal audit methodology, as it highlights the underlying systemic problem instead of merely documenting symptoms or assigning blame.

When there is a disagreement between the audit team and management, and if the disagreement concerns a significant risk, the issue should be escalated to the audit committee. The audit committee has the authority to review and resolve such disputes. Escalating the issue ensures that the concern is addressed at the highest governance level, maintaining the integrity and effectiveness of the internal audit function.

Probability-proportional-to-size (PPS) sampling is a technique used to reach conclusions regarding monetary amounts in a population. It is designed to handle variable sampling by focusing on monetary units, making it appropriate for testing account balances. On the other hand, attribute sampling is used to assess the rate of occurrence of a specific characteristic or attribute in a population, such as compliance with a control procedure, and does not focus on monetary amounts.

A limitation of a heat map is that it can be challenging to differentiate between impact and likelihood as to which is more important. Heat maps visually represent risks based on their impact and likelihood, but they do not inherently provide a mechanism to weigh these factors against each other, which can make prioritizing risks difficult in some cases.

* The IIA's Practice Guide on Risk Assessment discusses the use of heat maps in visualizing risks but also highlights their limitations, particularly in how impact and likelihood are presented. While heat maps are useful for a high-level overview, they may not provide the nuanced understanding needed for decision-making when both factors are critical.

Workpaper quality issues are a systemic problem that requires improvement of policies, procedures, and guidelines. Per Standard 2330 and 1311 (Internal Assessments), the CAE must establish processes to ensure quality documentation. Deletion (A) is inappropriate. A task force (B) does not address root cause.
Option D neglects the systemic issue. The best corrective action is developing and implementing clear guidelines and procedures (Option C).
