What is a key advantage of implementing "Continuous Integration and Continuous Delivery (CI/CD)" in Pega applications?

The key advantage of implementing Continuous Integration and Continuous Delivery (CI/CD) in Pega applications is frequent and seamless deployment of application changes. This approach allows developers to merge their code changes back to the main branch regularly, which leads to automated builds and testing. As a result, changes can be deployed to production swiftly and efficiently, minimizing the time it takes to deliver new features or fixes to end-users.

This rapid deployment capability not only enhances productivity but also supports better collaboration among development teams. It fosters an agile development environment where iterations can be made based on real-time feedback. As changes are tested continuously and delivered frequently, it reduces the risk of introducing significant bugs and allows teams to respond quickly to changing business requirements.

Other options do not align with the core advantages offered by CI/CD practices. For instance, increased reliance on manual testing contradicts the CI/CD principles which emphasize automation. Similarly, reducing end-user feedback goes against the continuous feedback loop that CI/CD strives to maintain, where user input is integral to development. Lastly, increased complexity of build processes is generally seen as a potential drawback, as CI/CD aims to simplify and streamline building and deployment rather than complicate it.
