Step-by-step explanation:
When a Scrum Product Owner is in the progress of creating a release plan, they should include a comprehensive set of information that covers various aspects of the release. This includes:
- Estimated user stories to provide a clear picture of the functionality that will be developed.
- Assignments of user stories to sprints to outline how the work will be distributed over the different iterations.
- Release dates to offer a timeframe for when features are expected to be available to the end-users.
