Clarifying Roles: Internal Audit and Compliance in the Three Lines Model
This article clarifies the distinct roles of Internal Audit and Compliance within an organization, particularly in the context of the Three Lines Model. It emphasizes that while both functions are crucial, their responsibilities are separate, preventing overlap and fostering a more effective governance structure. For audit professionals, understanding this distinction is vital for designing appropriate audit scopes and ensuring comprehensive assurance without duplicating efforts.
Understanding the Three Lines Model for Clearer Responsibilities
The article addresses a common concern among internal audit professionals: how to collaborate with the Compliance group without creating redundant efforts. It leverages the foundational concepts of the Three Lines Model (formerly Three Lines of Defense) to delineate the distinct responsibilities of Compliance (typically a 2nd-line activity) and Internal Audit (a 3rd-line activity). This framework is crucial for establishing clear boundaries and ensuring each function contributes uniquely to the organization's governance, risk management, and control processes.
Compliance's Dual Roles: Ownership vs. Advisory
The author explains that the Compliance function generally operates in one of two capacities: either directly owning compliance responsibilities or acting in an advisory role to management. When Compliance owns the responsibility, they are tasked with establishing policies, procedures, and monitoring mechanisms to ensure adherence to laws and regulations. In this scenario, Internal Audit's role is to independently assess the effectiveness of the Compliance function's processes and controls, rather than directly auditing the organization's compliance with regulations. This distinction is key to avoiding overlap and maintaining Internal Audit's objectivity.
Conversely, if Compliance serves in an advisory capacity, management retains direct ownership of compliance. Here, Internal Audit would evaluate the effectiveness of the Compliance function's advisory support. However, the article highlights a critical point: an audit of an advisory Compliance function is not a substitute for an audit of the organization's overall strategic compliance with laws and regulations. In such cases, Internal Audit may need to conduct a separate audit focusing on how the organization, through its first-line management, fulfills its strategic compliance obligations.
Strategic Auditing for Comprehensive Assurance
The core takeaway for internal audit professionals is the importance of understanding Compliance's specific mandate within their organization. This understanding dictates the appropriate scope for internal audit engagements. If Compliance owns the responsibility, Internal Audit audits their processes. If Compliance advises, Internal Audit assesses their advisory effectiveness, but also recognizes the potential need for a broader audit of the organization's strategic compliance efforts. By clearly defining these roles, internal audit can ensure comprehensive assurance coverage, avoid unnecessary duplication, and provide valuable insights into the effectiveness of the entire governance ecosystem.
