The Institute of Internal Auditors (IIA) is a global professional association that provides guidance and standards for the internal audit profession. The IIA has defined the mission of internal audit, the definition of internal auditing, and core principles for the professional practice of internal auditing, which outline the purpose, authority, and responsibility of the internal audit activity.

The mission of internal audit, as defined by the IIA, is to enhance and protect organizational value by providing risk-based and objective assurance, advice, and insight. This mission highlights the role of internal audit in adding value to an organization by assessing and providing assurance on the effectiveness of risk management, control, and governance processes. Internal auditors are expected to have an independent and objective mindset, and their work should help organizations achieve their objectives and improve their operations.

The definition of internal auditing, according to the IIA, is “an independent, objective assurance and consulting activity designed to add value and improve an organization’s operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes.” This definition emphasizes the dual role of internal auditing as both an assurance and consulting function. Internal auditors are responsible for evaluating the adequacy and effectiveness of an organization’s risk management, control, and governance processes, as well as providing advice and recommendations to improve these processes.

The IIA has also established core principles for the professional practice of internal auditing, which provide guidance on the fundamental principles that internal auditors should adhere to in their work. These core principles include:

  1. Integrity: Internal auditors should perform their work with integrity, which means being honest, fair, and truthful in all their professional activities. They should also maintain confidentiality and not disclose information without proper authorization.
  2. Objectivity: Internal auditors should be objective in their assessments and not let bias, conflict of interest, or undue influence compromise their professional judgment. They should base their findings and recommendations on reliable evidence and not be influenced by personal or external factors.
  3. Confidentiality: Internal auditors should respect the confidentiality of information obtained during their work and should not disclose it without proper authorization, unless required by law.
  4. Competency: Internal auditors should possess the knowledge, skills, and expertise necessary to perform their work effectively. They should also continuously improve their professional proficiency and stay updated with relevant laws, regulations, and best practices.
  5. Compliance: Internal auditors should comply with the IIA’s Code of Ethics, as well as applicable laws, regulations, and organizational policies and procedures. They should also exercise professional skepticism and challenge assumptions to ensure compliance is maintained.
  6. Reporting: Internal auditors should communicate the results of their work in a clear, concise, and accurate manner. They should report on the effectiveness of risk management, control, and governance processes, as well as provide recommendations for improvement.

The purpose of the internal audit activity is to provide independent and objective assurance to the organization’s management and board of directors on the effectiveness of risk management, control, and governance processes. Internal auditors are responsible for evaluating the adequacy and effectiveness of these processes in identifying, assessing, and managing risks, ensuring the reliability of financial and operational information, safeguarding assets, complying with laws and regulations, and achieving organizational objectives.

The authority of the internal audit activity is derived from the organization’s management and board of directors, and internal auditors should have unrestricted access to all records, personnel, and physical properties relevant to their work. Internal auditors should also be free from interference or influence that may compromise their independence and objectivity.

The responsibility of the internal audit activity is to provide independent and objective assurance and consulting services to the organization. This includes evaluating the design, implementation, and effectiveness of risk management, control, and governance processes

, conducting audits and assessments, identifying control deficiencies, providing recommendations for improvement, and monitoring the implementation of corrective actions. Internal auditors should also communicate the results of their work to management and the board of directors, as well as report on the status of outstanding audit recommendations.

The internal audit activity is also responsible for maintaining a quality assurance and improvement program to ensure that the internal audit function is operating effectively and in accordance with professional standards. This includes conducting periodic assessments of the internal audit activity’s conformance with the IIA’s International Standards for the Professional Practice of Internal Auditing, as well as implementing measures to continuously improve the internal audit function.

In summary, the IIA’s mission of internal audit emphasizes the role of internal audit in enhancing and protecting organizational value through risk-based and objective assurance, advice, and insight. The definition of internal auditing highlights the dual role of internal auditors as both assurance and consulting professionals, responsible for evaluating and improving risk management, control, and governance processes. The core principles for the professional practice of internal auditing provide guidance on the fundamental principles that internal auditors should adhere to in their work, including integrity, objectivity, confidentiality, competency, compliance, and reporting. The purpose, authority, and responsibility of the internal audit activity revolve around providing independent and objective assurance, conducting audits and assessments, and communicating results to management and the board of directors, while maintaining compliance with professional standards and continuously improving the internal audit function through a quality assurance and improvement program.

In conclusion, the IIA’s guidance on the mission, definition, and core principles for the professional practice of internal auditing, as well as the purpose, authority, and responsibility of the internal audit activity, provide a comprehensive framework for internal auditors to follow in their role as independent and objective evaluators of an organization’s risk management, control, and governance processes. Adhering to these principles helps ensure that internal auditors fulfill their responsibilities in a consistent, ethical, and effective manner, thereby contributing to the overall success of the organization.
