The rotational model of internal audit staffing involves bringing in staff from other parts of the organization for a temporary period before they return to their original roles. While this model has several advantages, such as bringing diverse perspectives and business knowledge, it also has the disadvantage that auditors are often new to the internal audit function and are continuously in training.
* Rotational Model:
* In this model, employees from various departments are rotated into the internal audit activity for a specific period. They gain audit experience before rotating back to their original or other roles within the organization.
* Disadvantages:
* Since these individuals are not career auditors, they may lack the deep audit expertise of career auditors, and a significant amount of time is often spent on training. This constant influx of new, inexperienced staff can lead to a scenario where the team is always in training mode, potentially impacting audit efficiency and effectiveness.
* IIA Practice Advisory 1210-1:
* The advisory notes that while the rotational model can enhance business understanding within the audit team, it requires careful management to ensure that audit quality is not compromised due to the continuous learning curve of rotating staff.
* Option A (Career model): This involves auditors who remain in the internal audit function throughout their careers, leading to a highly skilled and experienced team.
* Option B (Center of competence model): This model focuses on a centralized group of audit experts, ensuring specialized skills and consistency.
* Option D (Hybrid model): This combines elements of the rotational and career models, aiming to balance expertise with fresh perspectives.
Detailed Explanation:Why Not Other Options?

* A. Increased completeness:Correct. Coordination ensures comprehensive risk identification across diverse categories.
* B. Business managers can identify and assess risks:While true, this is not a primary advantage for internal audit coordination.
* C. The internal audit activity can rely on management's risk assessment:Internal audit should validate, not solely rely on management's assessment.
* D. Organizationwide audits are required:Misrepresents the purpose of risk universe coordination.

Option B is correct because the auditor is determining what occurred in the past -specifically, how many new service partners were attracted during the previous year. Descriptive analytics summarizes historical data and presents facts, counts, trends, distributions, and other measures concerning events that have already occurred. Diagnostic analytics, Option A, would seek to explain why the number of partners increased or decreased. Predictive analytics, Option D, would estimate how many partners may be attracted in a future period. Prescriptive analytics, Option C, would recommend actions designed to achieve a desired future result.
The CIA Part 2 syllabus expressly includes the use of data analytics and analytical techniques within Information Gathering, Analysis, and Evaluation. Because the question requires only measurement of a historical result, descriptive analytics is the appropriate method.

To prevent the situation where discrepancies identified by the auditor are corrected after being noted, it is essential to preserve the audit evidence. Taking screenshots or extracting tender documents would provide a permanent record of the discrepancies, ensuring that any subsequent changes do not invalidate the auditor ' s findings. This practice is crucial for maintaining the integrity of the audit evidence and supporting the audit conclusions. Option B is related but not as direct as preserving primary evidence. Options C and D do not address the preservation of evidence effectively.
The IIA ' s International Standards for the Professional Practice of Internal Auditing, Standard 2310 - Identifying Information.

Analytical review procedures involve the analysis of financial and operational data to identify trends, anomalies, or patterns that may indicate areas of concern or opportunities for improvement. In this scenario, where an organization is facing rising healthcare insurance costs, the most appropriate analytical review procedure is to compare the rate of increase in healthcare costs with an external benchmark, such as the government index of healthcare costs.
IIA Standard 2320 - Analysis and Evaluation:
The standard emphasizes the need for internal auditors to apply appropriate analytical procedures to understand the nature of data and assess the reasonableness of the information under review. Comparing the organization ' s cost increases to a government index provides an objective benchmark.
Benchmarking:
By comparing the organization's rate of increase in healthcare costs with the government index, the internal auditor can determine whether the organization's costs are in line with industry trends. This comparison helps assess whether the 10 percent annual increase is reasonable or if it deviates significantly from the norm.
Relevance of External Data:
The government index reflects the broader economic environment and industry standards, making it a relevant comparison point. If the organization's increase significantly exceeds the index, it may indicate inefficiencies or issues that require further investigation.
Option A (Comparison with similar organizations): While useful, this approach may not provide the same level of objectivity as a government index, as organizations may have different healthcare plans, demographics, and other factors affecting costs.
Option C (Obtaining a bid): This relates more to evaluating the cost-effectiveness of services, not the reasonableness of past cost increases.
Option D (Reviewing claims for overpayments): This is a detailed transactional audit, which is important but does not provide a broad analytical view of cost trends.
Detailed Explanation:Why Not Other Options?Conclusion: Option B is correct as it directly compares the organization's cost increase to an objective external benchmark, which aligns with IIA's emphasis on analytical review procedures for evaluating the reasonableness of financial data.
