How does Pega support rule versioning?

Pega supports rule versioning by maintaining multiple versions of rules for user selection. This functionality enables developers to create and modify rules without disrupting current processes or user experiences. When a new version of a rule is developed, the existing version remains intact and operational, allowing users to choose which version of the rule they want to use based on their needs or the specific business context.

This versioning approach is particularly beneficial in scenarios where changes need to be tested or gradually rolled out. Users can switch between different versions of the rule, which facilitates effective testing and ensures that any potential issues can be resolved without affecting the live application environment. It also allows for the management of changes over time, giving organizations the flexibility to adapt their applications as requirements evolve.

The other options do not accurately represent how Pega handles rule versioning. For example, the idea of automatically updating rules in real-time does not allow for testing or selecting between versions, while merging rules would negate the benefits of maintaining distinct versions. Lastly, a one-version policy would contradict the very purpose of versioning, which is to provide multiple options for selection and ensure smooth transitions between changes.
