What can a Development Team deliver at the end of a Sprint?

The Development Team is responsible for delivering an increment of working software that is "Done" at the end of each Sprint. This increment must meet the definition of "Done," which is a shared understanding among the Scrum Team of what it means for work to be complete. It ensures that the increment is potentially releasable and adds value to the product.

Delivering a "Done" increment means that the work is fully integrated, tested, and ready for use, thus providing immediate value to stakeholders and allowing for better feedback and planning for future increments. This practice aligns with the core principles of Scrum, where transparency and inspection during the Sprint Review foster adaptability in product development.

The other options, while potentially valuable in their own right, do not represent the primary deliverable of a Development Team in Scrum. Collecting feedback from stakeholders or providing reports on productivity are important activities, but they do not constitute a tangible increment of work. Delivering a single document as requested by the product owner, although it could be part of the work done in a Sprint, doesn't align with the broader objective of delivering a complete and integrated software increment. Thus, the emphasis in Scrum is on delivering functional increments of the product that enhance its usability and market relevance.
