Segregation of duties is one of the most critical functions of internal control, helping to reduce the risk of fraud and error. To be successful, it must be supported by clear policies and procedures that require multiple roles to be involved in the fundamental steps of a transaction.
Outlining clear segregation of duties within policies and procedures can lead to strong internal controls and a transparent operational environment.
The central premise of segregation of duties is that an individual shouldn’t be in a position to initiate, approve, and review the same transaction. The accounting, reconciliation, and custodial functions are incompatible duties and should each be assigned to separate roles within the organization. These functions should be clearly delineated within the policies and procedures.
Segregation of duties is typically viewed as a preventative control, as separating the individual tasks within a transaction cycle is done to reduce the risk that errors or omissions will occur in the first place. However, segregation of duties can also be useful in detecting errors or issues through the approval process.
Policies and procedures outlined to support adequate segregation of duties protect the organization and employees by ensuring that no one employee can perform all the steps involved in handling and accounting for financial transactions.
Key benefits include:
Developing and implementing comprehensive policies and procedures for key business cycles within your organization is essential to establish expectations, promote accountability, and ensure that risks are appropriately mitigated. Comprehensive policies and procedures include well-defined roles and responsibilities, ensuring that each stakeholder within a business cycle is clear on their role in the bigger picture and that adequate checks and balances are established. Segregation of duties is the fundamental principle of dividing tasks and responsibilities among different individuals to prevent conflicts of interest, errors, and potential fraud.
Simply put, segregation of duties distributes key functions among multiple team members, ensuring that no single person has complete control over a critical process. This not only helps in safeguarding sensitive data but also acts as a deterrent against internal threats and unintentional errors that may arise during business operations.
Consider a scenario where an organization's finance department is responsible for both setting up new vendors and initiating payments. Without proper policies requiring the segregation of key duties, a single employee could potentially set up a vendor, process payment to that vendor, and manipulate financial records to cover up fraudulent activities, such as embezzlement or unauthorized transactions.
By implementing segregation of duties, you can designate separate individuals for these tasks. One employee sets up new vendors and manages the vendor master list, while another is responsible for initiating payments. This division of duties acts as a checks-and-balances system, reducing the risk associated with financial misconduct and enhancing the integrity of financial processes.
Policies supporting segregation of duties outline the guidelines for task assignment while the procedures denote how those guidelines are implemented. Well-developed policies and procedures create a strong internal control environment, which includes segregation of duties.
