If a team cannot deliver a Done Increment by the end of a Sprint, they continue to work through the challenges and adapt their approach. The goal is to learn from the experience and make necessary adjustments to improve in future Sprints.
During the Sprint Review and Sprint Retrospective, the team evaluates what prevented them from meeting the Sprint Goal and identifies ways to address these issues. This might involve changes to the process, tools, or team dynamics, all aimed at increasing the likelihood of success in the next Sprint.
