Separation of Powers

Originating from political philosophy, separation of powers is a governance model that prevents the concentration of power. In enterprise risk management, it is implemented as Segregation of Duties (SoD), a fundamental internal control. SoD ensures that no single individual has exclusive control over all critical stages of a transaction or process. According to NIST SP 800-53 (control AC-5), its purpose is to prevent unauthorized actions and cover-ups of fraudulent activity. It involves separating the functions of authorization, custody, record-keeping, and reconciliation. This principle is a cornerstone of frameworks like COSO and is mandated by regulations such as the Sarbanes-Oxley Act (SOX).

In ERM, separation of powers is applied by implementing a robust Segregation of Duties (SoD) framework. The steps are: 1. **Identify High-Risk Processes**: Pinpoint critical business functions like procure-to-pay, order-to-cash, and IT administration where fraud or significant error could occur. 2. **Define and Map Conflicting Duties**: Create an SoD matrix that defines incompatible duties (e.g., creating a vendor vs. approving a payment to a vendor). Assign roles and responsibilities to ensure no single person performs conflicting tasks. 3. **Enforce and Monitor Controls**: Implement role-based access controls within ERP systems (like SAP or Oracle) to enforce the policy. Conduct periodic user access reviews and use automated GRC tools to continuously monitor for SoD violations. A global manufacturing firm reduced payment fraud by 90% after implementing automated SoD monitoring.

Taiwanese enterprises, particularly SMEs, face several challenges: 1. **Limited Staffing**: Fewer employees make it difficult to strictly segregate all duties. The solution is to implement compensating controls, such as mandatory job rotation, increased management oversight, and independent reviews of transaction logs. 2. **Trust-Based Culture**: A strong reliance on personal trust over formal processes can create resistance. Overcome this with top-down leadership communication that frames SoD as a mechanism to protect both the company and its employees. 3. **Legacy IT Systems**: Older systems may lack the granularity for effective role-based access control. The strategy is to prioritize system upgrades or deploy GRC software that can monitor for conflicts across disparate systems, starting with the most critical financial applications.
