How much work must a Development Team do to a Product Backlog item it selects for a Sprint?

The correct answer focuses on the importance of the relationship between the Development Team and the Product Owner along with the agreed-upon definition of "Done." When a Development Team selects a Product Backlog item for a Sprint, they commit to delivering a potentially shippable increment of that item by the end of the Sprint.

This commitment is made clear through communication with the Product Owner, who conveys the expectations and priorities regarding what is to be delivered. The definition of "Done" is a critical concept in Scrum; it outlines the criteria that must be met for a Product Backlog item to be considered complete. This may include aspects such as code quality, testing requirements, and documentation. By aligning their work with what they communicated to the Product Owner, the Development Team ensures accountability and sets clear expectations. Meeting these conditions helps in maintaining quality and reliability in their deliverables, which ultimately contributes to customer satisfaction and project success.

Focusing on the definition of "Done" ensures that the work is not only about completing tasks, but also about producing deliverables that add real value and meet agreed standards, making this the most comprehensive approach for the team's commitments during a Sprint.
