TheSprint Retrospectiveis heldafter the Sprint Review and before the next Sprint Planning. It is the final event in the Sprint, and its purpose is to reflect on the past Sprint and identify areas for improvement. The Scrum Team inspects how they worked during the Sprint in terms of processes, interactions, tools, and the Definition of Done, and then adapts for future Sprints.
According to the2020 Scrum Guide:
* The Sprint Retrospective is time-boxed and enables the team to inspect and adapt their working practices.
* It helps improve the Scrum Team's effectiveness in subsequent Sprints.
Why the other options are incorrect:
* B. At the beginning of the Sprint:The Sprint Retrospective is not held at the start of the Sprint. Sprint Planning occurs at the beginning of the Sprint.
* C. In the middle of the Sprint:Mid-Sprint is not a designated time for this meeting; the team is focused on achieving the Sprint Goal.
* D. At the end of all the Sprints:The Retrospective is held at the end ofeach Sprint, not at the conclusion of all Sprints.
