What is considered the completed increment in Scrum?

In Scrum, the completed increment is the releasable product delivered at the end of a sprint. This increment encompasses all the work that was completed during the sprint, including features, bug fixes, and other deliverables that meet the Definition of Done established by the team. The essential characteristic of this increment is that it must be functional and potentially shippable, aligning with Scrum principles that encourage delivering a working product frequently.

This understanding is crucial because it emphasizes the iterative nature of Scrum, where each sprint aims to build upon the previous increments and ensure that value is consistently delivered to stakeholders. The completed increment not only reflects the progress made by the team but also serves as a measure of what can be released to users or customers. It provides a tangible outcome that can be assessed and used for gathering feedback, thereby informing future development efforts.

Other choices do not align with the core concept of what constitutes a completed increment in Scrum. The tasks that were partially finished do not provide a complete product and cannot be considered releasable. An evaluation of team performance refers to assessing how the team operates rather than delivering product increments. A report of backlog items does not represent the actual product output but rather a list of work items yet to be addressed.
