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.

The observation provided in the final engagement communication includes the criteria (competitive bidding requirements), condition (three of the 10 contracts reviewed did not meet these requirements), and cause (senior management deemed these purchases critical and awarded them as sole-source). However, it lacks the effect, which would explain the potential consequences or impact of not meeting the competitive bidding requirements, such as increased costs, lack of transparency, or potential for favoritism.

The primary objectives of engagement supervision in internal auditing, according to IIA guidance, involve several key activities: identifying engagement objectives, assigning responsibilities to individual auditors, and approving the engagement program. These steps are essential to ensure that the audit is conducted effectively and that the objectives are met.

IIA Standard 2340 – Engagement Supervision:

This standard outlines the responsibilities of those supervising audit engagements. Supervisors must ensure that the audit is properly planned, that objectives are clearly defined, that the right personnel are assigned, and that the engagement program is appropriate for achieving the objectives.

Key Activities in Supervision:

Identifying Engagement Objectives: This is the first step in ensuring that the audit addresses the most important risks and areas of concern. The supervisor must ensure that these objectives are clear and aligned with the organization’s goals.

Assigning Responsibilities: Supervisors must ensure that tasks are allocated to auditors who have the appropriate skills and experience to carry them out effectively.

Approving the Engagement Program: The engagement program outlines the procedures and steps that will be taken to achieve the audit objectives. The supervisor’s approval ensures that the program is comprehensive and aligned with the audit’s goals.

IIA Practice Advisory 2340-1:

The advisory emphasizes the role of the auditor in charge in providing guidance, ensuring that objectives are met, and that the audit is conducted efficiently and effectively.

Option A (Enable training and development): While important, training and development are secondary objectives and not the primary focus of engagement supervision.

Option C (Training and development): Again, while important, these are supportive activities rather than the core focus of engagement supervision.

Option D (Training, development, and objectives): This option combines important activities but does not include assigning responsibilities, which is crucial in supervision.

Detailed Explanation:Why Not Other Options?

Depreciation methods allocate the cost of an asset over its useful life. Different methods impact the depreciation expense reported each year.

Option A: Sum of the years’ digits.

This is an accelerated depreciation method, which results in higher depreciation expense in the early years but not as high as the double-declining balance method.

Option B: Declining balance.

This method also results in higher depreciation expenses in the early years but is less accelerated compared to the double-declining balance method.

Option C: Double-declining balance.

This is the most accelerated method of depreciation among the options listed. It results in the highest depreciation expense in the early years of the asset's life. After the mid-service point of the asset, the double-declining balance method will still produce higher depreciation expenses compared to other methods.

Option D: Straight line.

This method results in equal depreciation expenses each year over the asset's useful life, leading to lower depreciation expenses in the later years compared to accelerated methods.

To test the theory that shutdowns are occurring due to outdated purchasing requirements that have not been updated for changes in production techniques, the auditor should compare the parts needed based on the most current production estimates and the revised materials requirements plan (MRP) with the purchase orders generated from the system. This comparison will help identify discrepancies between what is needed and what is being ordered, highlighting whether the system is failing to update purchasing requirements correctly. This method directly addresses the suspected cause of the shutdowns and provides clear evidence for or against the auditor’s theory.

Institute of Internal Auditors (IIA), International Standards for the Professional Practice of Internal Auditing (Standards), Standard 2310 – Identifying Information.

Internal auditors generally determine the priority of the areas within the engagement scope by assessing the risk of those areas. This involves estimating the likelihood of a risk occurring and the potential impact of that risk on the organization. High-risk areas with a high likelihood of occurrence and significant impact are prioritized to ensure that critical risks are addressed promptly. This risk-based approach to prioritization helps ensure that the audit resources are focused on the most significant areas, enhancing the effectiveness and efficiency of the audit.

Per Standard 2240 – Engagement Work Program, changes to the audit program must be reviewed and approved by the engagement supervisor to ensure they remain consistent with objectives. Therefore, the correct next step is to refer suggested changes to the supervisor for approval (Option A).
