What is the purpose of validation in Pega?

The purpose of validation in Pega is to confirm that data entered meets specific criteria before processing. This function ensures the integrity and accuracy of the data being captured in the application. By implementing validation rules, a Pega application can check whether the input data adheres to predefined formats, ranges, or logical relationships. This helps prevent errors, reduces the need for rework, and ensures that the business rules are upheld, resulting in more reliable output from the system.

The distinction of this choice lies in its alignment with the operational goals of the application. Other options, while they may contribute to the broader context of user experience or system flexibility, do not directly address the primary role of validation. User satisfaction, training sessions, and flexible data input are important aspects of application design and user interaction but do not specifically define the validation process.
