The internal audit team at Quantum Financial Services is assigned to conduct an audit of the new Algorithmic Trading Unit's risk management framework. The audit engagement leader, Ms. Evelyn Reed, has reviewed the team's competencies and found that while they possess strong financial audit skills and an understanding of general IT controls, none of the assigned auditors have specialized knowledge in advanced machine learning algorithms, high-frequency trading protocols, or the specific regulatory nuances of AI-driven trading models that the unit employs. The audit committee has set a tight deadline for reporting on the framework's effectiveness due to recent market volatility. What is Ms. Reed's most appropriate action to ensure the audit meets professional standards?

Worked Practitioner Scenario

Practitioner Application: Upholding Excellence: Competency, Due Professional Care, and CPE

An internal audit at a fast-growing fintech firm failed to identify a sophisticated algorithmic trading fraud. The audit team, while experts in traditional financial controls, lacked the specific data science and cybersecurity competencies to challenge the trading system's complex logic and security protocols. The result was a $50 million loss that went undetected for months—a loss that a properly skilled audit team could have prevented. This scenario underscores a fundamental truth: in internal audit, good intentions are not enough. Competence is non-negotiable.

  1. The Global Internal Audit Standards (GIAS) place competency and due professional care at the heart of an auditor's ethical obligations. This is not merely a 'best practice'; it is a mandatory requirement.
  2. GIAS Domain II: Ethics and Professionalism establishes this foundation through two key Guiding Principles:
Guiding Principle 3: Competency. This principle requires internal auditors to possess and apply the knowledge, skills, and experience needed to perform their responsibilities. If the team collectively lacks the required skills for an engagement, the Chief Audit Executive (CAE) must obtain competent advice and assistance or decline the engagement. Guiding Principle 4: Due Professional Care. This principle builds on competency, requiring auditors to act with the care and skill expected of a reasonably prudent and competent internal auditor. This includes considering the complexity of the engagement, the significance of the matters to which assurance procedures are applied, and the adequacy of risk management and control processes. Simply put, you cannot exercise due professional care if you are not competent in the first place.

Common IIA CIA Distractors on COSO

  • 1Use this framework to dissect and solve exam questions related to competency and due professional care.
  • 2Step 1. Identify the Core Issue. Is the question about the entire function's ability (a CAE's strategic decision) or an individual auditor's actions? This distinction is key to selecting the right response.
  • 3Step 2. Scan for Competency Gaps. Look for keywords indicating a mismatch between the engagement's needs and the auditors' skills, such as 'complex IT system,' 'specialized fraud scheme,' or 'no prior experience.'
  • 4Step 4. Eliminate Inappropriate Options. Discard answers that violate professional standards. These include proceeding without addressing the gap ('learn on the job'), ignoring the issue, or assigning the task to an unqualified person without adequate support.
  • 5To remember the key elements of a robust competency management program, use the mnemonic C-A-R-E:
