During Sprint Planning, what helps the Development Team determine how many Product Backlog items to select?

The correct option is projected capacity of the Development Team. During Sprint Planning, it is crucial for the team to assess how much work they realistically can commit to completing within the upcoming Sprint. This assessment is guided by understanding their capacity, which involves considering factors like team availability, any planned vacations, holidays, and potential interruptions during the Sprint.

Capacity helps the team make informed decisions about how many Product Backlog items they can effectively tackle while maintaining quality and meeting their commitments. By evaluating their capacity, the Development Team can prioritize items from the Product Backlog that they are confident they can deliver within the Sprint timeframe.

While familiarity with the Product Owner, the Definition of "Done," and stakeholder input can play roles in the overall Sprint Planning discussions and help shape priorities and expectations, the specific focus on determining how many Product Backlog items can be selected is fundamentally rooted in the team's capacity. This consideration ensures a realistic and sustainable approach to managing workload and delivering value.
