Who is responsible for creating and modifying the Increment in a Scrum Team?

The responsibility for creating and modifying the Increment in a Scrum Team primarily lies with the Developers. This role encompasses not only coding but also all activities necessary to build a potentially shippable product increment, including design, testing, and integration. Developers work collaboratively during the Sprint to transform Product Backlog items into a usable Increment, adhering to the Definition of Done established by the Scrum Team.

While other roles in Scrum, such as the Scrum Master and the Product Owner, play vital roles in supporting the team and ensuring that the work aligns with the broader goals and priorities, it is the Developers who execute the tasks necessary for the creation of the Increment. The collaboration among the entire Scrum Team is essential for successful outcomes, but the actual responsibility of delivering the Increment rests with the Developers.
