What approach is essential for tracking changes within Pega applications?

Using versioning is essential for tracking changes within Pega applications because it allows developers to manage and maintain different iterations of application rules and data. In Pega, versioning ensures that any updates or modifications can be systematically recorded and rolled back if necessary, providing a clear history of changes made over time. This practice not only enhances collaboration among team members but also mitigates the risks associated with changes, ensuring that previous versions can be accessed easily if an issue arises with the current version.

With versioning, each change can have its own identifiers and be associated with specific releases, making it easier to identify and resolve inconsistencies or regressions in application behavior. This systematic method of tracking ensures that the development lifecycle remains organized and compliant with best practices, facilitating easier deployment and maintenance of Pega applications.
