How much work must a Development Team do on a Product Backlog item selected for a Sprint?

The Development Team must complete the amount of work they have committed to delivering during the Sprint in alignment with their definition of "Done." This commitment is established during the Sprint Planning meeting, where the team selects the items from the Product Backlog they believe they can complete during the Sprint.

The definition of "Done" provides a clear understanding of what it means for work to be complete. It can include aspects such as code quality, testing, documentation, and any other criteria necessary for an increment to be considered potentially releasable. By adhering to this definition, the team ensures that the work they deliver meets quality standards and truly adds value to the product.

This choice highlights the self-organizing nature of Development Teams and emphasizes accountability for their commitments, reflecting a core principle of Scrum where the team takes ownership of its work.
