Final answer:
In computerized systems, segregation of duties is crucial to prevent fraud and errors, even though entry controls can greatly support accuracy and integrity of data.
Step-by-step explanation:
The question pertains to how duties and controls are managed in a computerized system. It suggests a scenario where protocols are configured to support human decision-making within such a system. The proper approach in a computerized system is to maintain a segregation of duties to prevent fraud and errors. This means that the system should have adequate entry controls and checks to verify the inputs and operations being made.
In some cases, a computerized system can have controls that are so effective that segregation of duties becomes less critical, but this doesn't completely eliminate the need for it. For instance, while entry controls may ensure data integrity to a high degree, having different individuals oversee various aspects of the system's operation remains a best practice to ensure checks and balances.
