Which of these may a Development Team deliver at the end of a Sprint?

The Development Team delivers an increment of working software that is "done" at the end of a Sprint. This aligns perfectly with the fundamental principles of Scrum, where the objective of each Sprint is to produce a potentially releasable product increment.

By ensuring that the delivered increment meets the team's Definition of Done, the Development Team confirms that it is not just a collection of incomplete features but a fully functioning addition to the product. This demonstrable and usable increment enables stakeholders to assess progress, gather feedback, and make informed decisions for future development.

The focus on delivering a working increment of software emphasizes the iterative and incremental nature of Scrum, fostering regular feedback and adaptation to changing requirements or market needs. This delivery aligns with the core Scrum values of transparency and inspection, enabling continuous improvement and facilitating collaboration among Scrum Team members and stakeholders.
