The internal audit activity is a critical function within an organization that provides independent and objective assurance and consulting services to add value and improve the organization’s operations. To effectively fulfill its responsibilities, the internal audit activity requires a range of knowledge, skills, and competencies. Let’s explore these in detail, along with definitions and examples:

Financial Accounting and Reporting:

Internal auditors need to possess a strong understanding of financial accounting principles and reporting standards. This includes knowledge of Generally Accepted Accounting Principles (GAAP) or International Financial Reporting Standards (IFRS), as well as an understanding of financial statements, financial analysis, and financial controls. Internal auditors may need to review financial transactions, assess financial risks, and ensure that financial reporting is accurate and in compliance with applicable standards.

Example: An internal auditor reviewing the financial statements of a company identifies irregularities in revenue recognition practices, leading to the identification of potential financial reporting risks and the recommendation of appropriate corrective measures.

Risk Management:

Internal auditors must have a solid understanding of risk management concepts and methodologies. This includes identifying, assessing, and managing risks across various areas of the organization, such as operational, financial, compliance, and strategic risks. Internal auditors may need to evaluate the effectiveness of the organization’s risk management processes and provide recommendations for mitigating risks.

Example: An internal auditor conducts a risk assessment of a manufacturing facility to identify potential operational risks, such as equipment failures, supply chain disruptions, and production delays. The internal auditor then recommends controls and process improvements to mitigate these risks and enhance operational efficiency.

Internal Controls:

Internal auditors should have a thorough knowledge of internal control frameworks, such as the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework, and be able to assess the effectiveness of internal controls. This includes understanding the design, implementation, and testing of internal controls to ensure that they are adequate and operating effectively to mitigate risks and safeguard organizational assets.

Example: An internal auditor conducts a review of the procurement process in an organization and assesses the design and effectiveness of internal controls, such as segregation of duties, purchase authorization, and vendor management. The internal auditor identifies control weaknesses and recommends improvements to enhance the procurement process’s integrity and effectiveness.

Audit Methodology:

Internal auditors should be proficient in audit methodologies, including risk-based audit approaches, data analytics, and audit testing techniques. This includes planning, executing, and reporting on audits in accordance with established audit standards, policies, and procedures. Internal auditors should also be skilled in using audit software and tools to collect, analyze, and interpret data to support audit findings.

Example: An internal auditor uses data analytics tools to analyze large volumes of financial data and identify patterns of potential fraudulent activities. The internal auditor then conducts detailed testing and provides evidence-based findings to support the conclusion of fraudulent activities and recommends appropriate actions to mitigate the risk of fraud.

Communication and Presentation:

Internal auditors must possess excellent communication skills, both written and verbal, to effectively communicate audit findings, recommendations, and reports to stakeholders. This includes the ability to convey complex information in a clear, concise, and meaningful manner. Internal auditors should also be skilled in active listening and be able to communicate with diverse audiences, including senior management, employees, and external stakeholders.

Example: An internal auditor prepares a comprehensive audit report summarizing the findings, conclusions, and recommendations of an audit engagement. The report is well-structured, clearly written, and presents the information in a manner that is easily understood by senior management and the audit committee, facilitating informed decision-making.

Ethical Conduct:

Internal auditors are expected to adhere to high standards of ethical conduct and integrity. This includes maintaining confidentiality, objectivity, and independence in all audit activities, as well as complying with the organization’s code of ethics and professional standards. Internal auditors should also demonstrate a strong sense of professionalism, integrity, and accountability in their work and interactions with others.

Example: An internal auditor is conducting an audit of the procurement process and discovers evidence of potential fraud involving a senior executive. The internal auditor maintains strict confidentiality, follows the organization’s established procedures for reporting suspected fraud, and ensures that the investigation is conducted objectively and independently, without any bias or undue influence.

Critical Thinking and Problem Solving:

Internal auditors need to possess strong analytical and problem-solving skills to assess complex situations, identify issues, and develop appropriate solutions. This includes the ability to analyze data, evaluate risks, assess controls, and make sound judgments based on available evidence. Internal auditors should also be able to think critically, ask probing questions, and challenge assumptions to arrive at well-supported conclusions and recommendations.

Example: An internal auditor is assigned to investigate a significant inventory discrepancy in a warehouse. The internal auditor conducts a thorough review of inventory records, performs physical inventory counts, interviews warehouse personnel, and identifies control weaknesses in the inventory management process. Based on the analysis and evidence gathered, the internal auditor identifies the root cause of the discrepancy as a lack of proper inventory controls and recommends implementing tighter controls and regular reconciliations to mitigate the risk of inventory discrepancies.

Relationship Management:

Internal auditors need to build and maintain effective working relationships with various stakeholders, including management, employees, and external parties. This includes the ability to communicate clearly, collaborate, and establish trust and credibility. Internal auditors should also be able to navigate challenging situations, handle conflicts professionally, and influence others in a positive manner.

Example: An internal auditor is conducting an audit of the human resources department and needs to gather information from multiple employees at different levels of the organization. The internal auditor establishes rapport with the employees, actively listens to their concerns, and communicates the purpose and scope of the audit in a clear and non-threatening manner. The internal auditor maintains a professional and respectful approach, which fosters open communication and cooperation from the employees, resulting in a successful audit.

Continuous Learning:

Internal auditors need to have a mindset of continuous learning and professional development to stay updated with the latest industry trends, regulations, and best practices. This includes participating in training programs, attending conferences, and seeking opportunities to enhance their knowledge and skills. Internal auditors should also be proactive in staying informed about changes in the organization’s operations, processes, and risks to effectively assess and address emerging issues.

Example: An internal auditor proactively seeks opportunities to enhance their knowledge in data analytics and attends a specialized training program to gain proficiency in using advanced analytics techniques in audits. The internal auditor applies the newly acquired skills in an audit engagement, which significantly improves the effectiveness and efficiency of the audit, and the findings and recommendations are well-received by management.


In conclusion, the responsibilities of the internal audit activity require a broad range of knowledge, skills, and competencies. Internal auditors need to possess expertise in financial accounting and reporting, risk management, internal controls, audit methodologies, communication and presentation, ethical conduct, critical thinking and problem solving, relationship management, and continuous learning. By developing and leveraging these competencies, internal auditors can effectively fulfill their responsibilities and contribute to the organization’s success by providing valuable insights, recommendations, and assurance on the effectiveness of risk management, control, and governance processes.
