In the scenario where an internal auditor assisted with management's design of controls over the procurement function, the chief audit executive should plan an assurance engagement on the adequacy of the internal control system by assigning the engagement to another internal auditor on staff. This approach ensures that the evaluation of the controls is conducted with objectivity and independence, as the auditor who helped design the controls may have an inherent bias.

IIA Standards regarding objectivity and independence in assurance engagements.

According to IIA guidance, the internal audit charter is a critical document that defines the purpose, authority, and responsibility of the internal audit activity. It is endorsed by the organization's governing body and establishes the internal audit function's position within the organization, including its reporting lines and access to records and personnel.

To assess whether the independence of the internal audit activity is at risk of being compromised, reviewing the internal audit charter provides the best source of evidence. This document outlines the independence and objectivity of the internal audit function and specifies the reporting structure to senior management and the board, which are essential elements in safeguarding independence.

The internal auditor's failure to identify the origins of a significant control issue before concluding the engagement suggests a lack of critical thinking skills. Critical thinking involves analyzing and evaluating an issue thoroughly to understand its root causes before forming a judgment. Improving this skill would enhance the auditor's ability to conduct deeper analyses and provide more valuable insights in audit reports.

The type of risk that an adequately designed and effectively operating system of internal controls should mitigate is "Residual" risk. Residual risk is what remains after internal controls are applied to inherent risk. This is the primary focus of most internal control systems, which are intended to reduce risks to an acceptable level.
