Demonstrating due professional care during an assurance engagement, according to IIA standards, includes systematically planning, executing, and documenting audit procedures. This ensures that all aspects of the engagement are covered comprehensively and that findings and conclusions are well-supported and credible. This approach aligns with the IIA's definition of due professional care, which emphasizes thoroughness and accuracy in the audit process.

The Institute of Internal Auditors (IIA) - International Standards for the Professional Practice of Internal Auditing.

The most likely reason for an internal auditor failing to identify transactions between the parent organization and a subsidiary is a lack of understanding of the organization. Understanding the organizational structure, including relationships between parent and subsidiary entities, is crucial for identifying and evaluating intercompany transactions. A thorough knowledge of the organization's operations, financial arrangements, and business processes enables auditors to recognize and properly assess such transactions during their audit engagements.

Critical thinking skills are essential for internal auditors when designing audit procedures and selecting samples. The situation described indicates that the auditor relied on a sampling method without thoroughly considering the potential risks and the specific context of the transaction population. Improved critical thinking skills would help the auditor better assess the representativeness of the sample, identify potential fraud risks, and ensure a more thorough and effective audit approach, potentially preventing the oversight that led to undetected fraud.

The IIA Standards: Standard 1220 – Due Professional Care: "Internal auditors must apply the care and skill expected of a reasonably prudent and competent internal auditor. Due professional care includes consideration of the use of technology-based audit and other data analysis techniques."

IIA Practice Guide: "Assessing the Adequacy of Risk Management and Controls": Emphasizes the importance of critical thinking in evaluating risks and controls.

According to IIA guidance, the most effective training method in assisting new entry-level internal auditors in achieving competence with internal audit practices is involvement in a variety of audit assignments. Hands-on experience across different audits allows new auditors to apply theoretical knowledge practically, learn from real-world scenarios, and develop a deeper understanding of audit processes and challenges.
