How much work must a Development Team complete on a selected Product Backlog item during a Sprint?

The correct answer focuses on the importance of communication between the Development Team and the Product Owner regarding the amount of work to be completed during a Sprint. It recognizes that the Scrum framework is built on collaboration and transparency. The Development Team commits to a certain amount of work during the Sprint Planning meeting based on the understanding and agreement with the Product Owner about what can realistically be accomplished within the Sprint's time frame.

This approach helps set clear expectations for what the Development Team aims to complete, allowing for adjustments based on feedback, team capacity, and the complexity of the selected Product Backlog items. By ensuring that the work aligns with what has been communicated, the team fosters a strong partnership with the Product Owner, enabling better prioritization and agile response to changing requirements.

In contrast, completing all work defined in the initial project scope (as suggested by another option) may not be realistic, especially in an agile environment where requirements can evolve. Simply doing the minimum for demonstration purposes undermines the commitment to delivering potentially shippable increments of product each Sprint. Lastly, depending on tasks completed by other teams does not give the Development Team the autonomy or accountability required in Scrum, as each team is responsible for its portion of work irrespective of others' contributions.
