What advantage does versioning provide in a modular Pega application?

The advantage of versioning in a modular Pega application primarily lies in the ability to track changes and maintain old versions. This capability is crucial for any software development process, as it allows teams to manage and revert to previous versions of application components when necessary, ensuring stability and reliability.

With versioning, developers can document the evolution of the application, allowing for easier debugging and understanding of how the application has changed over time. This not only aids in troubleshooting but also provides a clear audit trail of changes made, which is essential for compliance and governance within organizations.

Additionally, maintaining old versions enables a smoother transition when new features or fixes are introduced, as teams can test them in isolation without disrupting the current production environment. This functionality ensures that organizations can safeguard against potential issues that might arise from new releases, thereby enhancing the overall quality assurance process.

While other options may have some merit in a broader context, they do not capture the primary benefit of versioning, which is fundamentally about change management and historical tracking.
