Final answer:
To ensure each user story is approved by the release manager upon completion, a company can implement an automated workflow or a manual notification system, together with clear guidelines and strict compliance checks.
Step-by-step explanation:
In order to accomplish the goal of having each user story approved by the release manager when its status changes to Completed, your company can set up a business process that involves an automated workflow or a manual notification system. The process could require that upon a user story's completion, an automatic alert or notification is sent to the release manager indicating that a review is needed. Alternatively, the business could implement a manual system where team members are trained to inform the release manager directly when a story reaches completion. Regardless of automated or manual, clear guidelines must be established to ensure that this policy is consistently applied and monitored for compliance. This often includes setting up roles and permissions within a project management software or tracking system that requires release manager sign-off before the story can be officially marked as completed within the system.
