The primary determinant of the objectives and scope of assurance engagements is the preliminary risk assessment performed by internal auditors. This assessment identifies the key risks associated with the area under review and helps prioritize the audit efforts based on the significance and likelihood of these risks. This approach ensures that the engagement focuses on the most critical areas, thereby adding value to the organization.

The International Standards for the Professional Practice of Internal Auditing (Standards) emphasize the importance of risk-based planning in determining the scope and objectives of audit engagements. Standard 2200 (Engagement Planning) and Standard 2210 (Engagement Objectives) provide guidance on this process​​.

Probability-proportional-to-size (PPS) sampling, also known as monetary unit sampling, is most appropriate for measuring the total misstatement in an accounts payable ledger. This method is used to determine the likelihood of individual items being selected based on their size, with larger items having a higher probability of being selected. This is particularly useful in identifying overstatements and misstatements in financial records, such as accounts payable, where the monetary value of transactions is a critical factor.
