Which of the following is the GREATEST benefit of a three lines of defense structure?

While an effective risk culture is a desirable outcome, the primary structural benefit of the three lines of defense model is the clarity it provides regarding risk accountability, which then supports culture development.

Effective segregation of duties is an important internal control, but the three lines of defense model addresses the broader organizational structure for managing *all* types of risks, not solely focusing on fraud prevention.

The three lines of defense model clearly defines distinct roles and responsibilities across the organization for risk management, including operations (first line), risk and compliance functions (second line), and internal audit (third line). This clear delineation ensures that accountability for identifying, assessing, managing, and monitoring risks is well-established, preventing gaps or overlaps in oversight.

Improved effectiveness and efficiency of business operations can be a positive consequence of better risk management, but the core benefit of the three lines of defense structure is its clear assignment of risk responsibilities.
