What action do system architects take when case behavior needs to be changed in Pega?

When case behavior needs to be changed in Pega, versioning rules is the appropriate action for system architects to take. Versioning allows modifications to be introduced while retaining the original version of the rule. This ensures that existing cases utilizing the old version continue to function as intended, providing stability for current users and systems. It also allows new cases to take advantage of the updated functionality without disrupting the workflow of ongoing processes.

Versioning is particularly important in environments where rules may be frequently adapted to meet changing business requirements. By creating a new version, architects can refine case behaviors or introduce new business logic, ensuring that all changes are traceable and manageable within the rule framework.

In contrast, delegating rules to business users may restrict the implementation of comprehensive changes to technical aspects of case behavior, while reusing existing rules could limit adaptability. Simply replacing old rules with new ones could also introduce risks and instability, as this would affect all cases using the original rule without considering their context or needs. Therefore, leveraging versioning is a strategic approach that enhances governance and flexibility in Pega applications.
