The International Standards for the Professional Practice of Internal Auditing encourage auditors to acknowledge satisfactory performance to provide a balanced report. However, it is not a mandatory requirement. Including positive observations can help foster a constructive relationship with management and provide a more balanced view of the audited area.

Adding invoices to the computer program to assess the reliability and effectiveness of the review process and whether controls work best describes an internal auditor's use of test data. This approach involves introducing test data into the system to evaluate how well the system processes invoices and whether it effectively identifies and prevents questionable invoices from being processed for payment.

The corporate risk register is a comprehensive document that records identified risks, their assessment in terms of likelihood and impact, and the controls in place to manage them. It reflects the organization's attitude toward risk and highlights areas where achieving objectives may be difficult. The CAE should consult this resource to align the audit plan with the organization's risk profile and ensure that high-risk areas are appropriately audited. References:

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.

According to IIA guidance, risk assessment is a critical step that precedes the development of audit engagement objectives. The risk assessment process helps internal auditors identify the key areas of risk within the organization, which then informs the setting of appropriate objectives for the audit engagement.
* IIA Standard 2201 - Planning Considerations:
* This standard requires internal auditors to consider risk when planning an engagement. The risk assessment process identifies the areas of highest risk, which allows the auditor to focus on the most critical issues during the engagement.
* Role of Risk Assessment:
* By assessing risks, the auditor can determine which processes or controls are most likely to affect the achievement of the organization's objectives. This understanding is essential for setting the audit engagement's objectives, ensuring that they are aligned with the areas of greatest concern.
* IIA Practice Advisory 2210.A1-1:
* The advisory suggests that auditors should use the results of the risk assessment to establish the scope, objectives, and priorities of the engagement. Without this risk assessment, the audit objectives may not fully address the most significant risks.
* Option A (Identification of controls): This typically occurs after the objectives are set, as controls are evaluated based on the identified risks.
* Option B (Scope establishment): The scope is determined after the objectives are set, which are based on the risk assessment.
* Option D (Review of resources): This step is related to the allocation of resources after the objectives and scope are defined.
