Judgmental sampling, also known as non-statistical sampling, is a technique where the internal auditor uses their professional judgment to select a sample that they believe is most representative of the population. In this scenario, the internal auditors are choosing to review a sample of complaints from the last three months based on their professional judgment that these complaints are reflective of current marketing practices. This method is particularly useful when the auditor has specific knowledge about the population that allows them to make informed selections.

Given the urgency and the lack of internal expertise in forensic investigation, the most effective and immediate solution is to outsource the investigation to independent professional consultants. This approach ensures that the investigation is conducted by individuals with the necessary skills and experience, thereby maintaining the integrity and quality of the investigation. Training internal staff or recruiting new auditors would take time and may not address the immediate need, while declining the engagement would not fulfill the audit committee ' s request.

When determining the level of staff and resources for an assurance engagement, the most relevant factor for the chief audit executive (CAE) is the availability of resources with the specific skill set required for that particular engagement. This is because assurance engagements often involve complex and specialized areas that necessitate specific expertise to effectively evaluate controls, risks, and processes.

IIA References:

IIA Standard 2230: Engagement Resource Allocation states that internal auditors must determine appropriate and sufficient resources to achieve engagement objectives based on an evaluation of the nature and complexity of each engagement, time constraints, and available resources. The emphasis is on ensuring that the team assigned to the engagement possesses the necessary skills and knowledge.

The Practice Advisory 2230-1 further suggests that the CAE should consider the complexity and risks associated with the engagement and ensure that the assigned team has the appropriate experience and technical skills.

 Role of the CAE: The Chief Audit Executive (CAE) is responsible for developing a risk-based audit plan and ensuring it is aligned with the organization’s goals and emerging risks. Significant changes to the audit plan must be communicated appropriately within the organization.

 IIA Standards:

Standard 2020 – Communication and Approval: The CAE must communicate the internal audit plan and resource requirements, including significant interim changes, to senior management and the board for review and approval.

Risk Assessment: Any changes to the audit plan due to emerging risks, such as a corporate merger, must be documented and approved at the highest levels to ensure comprehensive risk coverage.

 Most Appropriate Action:

Communication with the CEO: The CAE should first discuss the revised audit plan with the CEO to ensure alignment with executive management’s perspective on emerging risks.

Board Approval: After discussing with the CEO, the CAE should present the revised audit plan to the board for formal approval, ensuring transparency and governance.

 References:

Presenting the revised audit plan to the board after discussing with the CEO ensures that all relevant stakeholders are informed and that the revised plan is formally approved, maintaining alignment with IIA standards​​​​.

The initial step the CAE should take is to discuss the issue with the members of management responsible for the risk area. This discussion allows the CAE to understand the reasons for the lack of action, provide an opportunity for management to explain their position, and encourage them to implement the necessary mitigation measures. If this discussion does not lead to satisfactory action, the CAE would then escalate the issue to senior management or the board as appropriate.

The most likely reason the Chief Audit Executive (CAE) decided to prepare an audit memorandum for management of the logistics department is to allow management to address the identified weakness timely. An audit memorandum serves as a formal communication that highlights the issue and provides management with the necessary details to understand and address the control weakness promptly. This approach facilitates immediate corrective action, thereby reducing the risk associated with the identified weakness.

The Institute of Internal Auditors (IIA) Standard 2420 – Quality of Communications: " Communications must be accurate, objective, clear, concise, constructive, complete, and timely. "

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.

IIA References:

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.

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.

The primary advantage of using internal control questionnaires (ICQs) as part of a preliminary survey for an engagement is their efficiency. ICQs allow auditors to quickly gather a large amount of information about the control environment by asking structured questions that cover key areas of interest. This helps in identifying areas that require further investigation or where controls may need improvement.

IIA References:

The IIA’s Practice Guide on Evaluating Internal Controls mentions that ICQs are useful for obtaining an initial understanding of controls and are particularly efficient when time or resources are limited. They allow auditors to systematically cover a wide range of control-related topics in a relatively short period.

Both job order cost systems and process cost systems track three manufacturing cost elements: direct materials, direct labor, and manufacturing overhead. These cost elements are essential in calculating the total production cost and determining the cost per unit.

Direct Materials: The raw materials directly used in the production of goods.

Direct Labor: The wages of workers who are directly involved in manufacturing the products.

Manufacturing Overhead: Indirect costs associated with production, such as utilities, maintenance, and depreciation of equipment.

According to Standard 2240 – Engagement Work Program, work programs must be developed to achieve engagement objectives. The primary purpose is to guide the audit team in understanding the tasks, procedures, and testing steps necessary to accomplish objectives. While supervision and communication are secondary benefits, the main reason is to help auditors understand and execute their responsibilities (Option B).

A significant governance issue that must be reported to the board is the absence of a formal risk management and control process, with risk management being solely the responsibility of operational managers. Effective governance requires a structured risk management framework overseen at the highest levels of the organization. The lack of such a process indicates a critical deficiency that can have severe implications for the organization ' s ability to manage and mitigate risks.

The Institute of Internal Auditors (IIA) Standard 2110 – Governance: " The internal audit activity must assess and make appropriate recommendations to improve the organization’s governance processes. "

The focus of the effect section of the preliminary observations document should be on residual risk. Residual risk is the remaining risk after management has taken action to mitigate the inherent risk with controls and other risk responses. Documenting the effect in terms of residual risk helps in understanding the potential impact of the observed issues on the organization if not addressed.

The most important determinant of the objectives and scope of assurance engagements is the preliminary risk assessment performed by internal auditors. This assessment identifies the key risks that the engagement should address and ensures that the audit is focused on areas of highest risk and significance to the organization. While organizational charts, business objectives, and management requests are important inputs, the internal auditors ' preliminary risk assessment ensures that the audit addresses the most critical areas.
