What is the primary benefit of implementing separation of duties as a control?

• A. It ensures all tasks are performed by a single individual.
• B. It eliminates the need for any audits.
• C. It guarantees zero errors in financial reporting.
• D. It reduces the risk of fraud by enabling checks and balances.

Answer: (D)

Separating duties works by dividing key steps of a process among different people so no one person controls all aspects. This creates checks and balances: one person authorizes a transaction, another records it, and a third handles the asset. Because different people verify and review parts of the process, fraudulent acts or errors are more likely to be detected, and it becomes much harder to both commit and conceal a misstatement. In short, the control reduces the opportunity for fraud by requiring independent verification and oversight. Even though audits and reviews remain important, this approach does not eliminate the need for them, and it does not guarantee zero errors. If staffing is limited, compensating controls like independent reconciliations or management oversight can help maintain the same protective effect.
