What is included in the Sprint Backlog?

The Sprint Backlog consists of the set of items selected from the Product Backlog for the current Sprint, along with any further breakdown or decomposition of these items into manageable tasks. This means that it not only includes user stories but also any other deliverables that the Scrum Team has determined are necessary to fulfill the Sprint Goal.

By focusing on the decomposition of these selected Product Backlog items, the team creates clear tasks that can be worked on during the Sprint, enhancing transparency and enabling effective tracking of progress. This allows team members to understand what needs to be accomplished and how they can collaborate to complete the work within the Sprint time-box.

The other options, while related to the team's work, do not encapsulate the comprehensive nature of the Sprint Backlog. For example, limiting the Sprint Backlog to only user stories would overlook other important elements necessary for a successful Sprint. Similarly, while tasks assigned to team members may be part of what the Sprint Backlog contains, the definition of the Sprint Backlog is broader and encapsulates all relevant activities and deliverables. Test cases, on the other hand, while essential for quality assurance, are only a subset of what may come out of the user stories; they do not fully represent the entirety of the Sprint
