The development team for a customer-facing e-commerce application has finished coding a new one-click checkout feature during the current sprint. The code compiles successfully, and the feature demo was well received in the sprint review. Deployment to the production Kubernetes cluster is scheduled for this weekend's maintenance window. During the change-control meeting, which action should the project manager insist be completed first to maximize confidence that the release will not disrupt existing shopping and payment functions?
Conducting thorough testing of the new feature in a representative test or staging environment is essential. Functional, regression, and performance tests confirm that the code behaves as expected and does not break existing checkout, inventory, or payment processes. Finding defects before production protects customer experience and brand reputation. Notifying customers is important for transparency, a rollback plan is prudent risk management, and stakeholder approval provides governance; however, none of these activities directly validate that the software works correctly or remains stable. Only rigorous testing provides objective evidence of quality before the production push.
