A sprint retrospective is a meeting that takes place at the end of each sprint, where the team reflects on what went well and what can be improved in their work process. The purpose of the retrospective is to identify and implement actions that can enhance the team's performance and satisfaction in future sprints. Two basic questions that can help facilitate the retrospective are: What went well? and What didn't go well and can be improved? These questions allow the team to celebrate their achievements, acknowledge their challenges, and generate ideas for improvement.
