Which feature allows for the versioning of rules in Pega?

The feature that allows for the versioning of rules in Pega is rule sets. Rule sets serve as containers for organizing and managing rules within the application. Each rule set can contain multiple versions, enabling developers to create, modify, and manage different versions of rules over time. This versioning capability is crucial for maintaining application stability, conducting parallel development efforts, and ensuring that changes can be tracked and rolled back if necessary.

When a new version of a rule is created, it is typically assigned to a specific rule set version, allowing developers to control which version of the rule is in use as well as when a specific version becomes active. This structured approach to versioning not only facilitates collaboration among multiple developers but also aligns with Pega’s best practices for application deployment and governance.

Other options like case management, data pages, and service level agreements do not provide versioning capabilities for rules. Case management focuses on managing the workflow and processes of cases, data pages are used for managing data access and integration, and service level agreements define the expected service levels for case handling, rather than managing the versions of rules.
