How long should a retro last?

How long should a retro, or reflection session, last? This is a question that often arises in the realm of project management and team development. On one hand, you want to ensure that the team has ample time to thoroughly discuss their successes, challenges, and potential improvements. On the other hand, you don't want to overextend the session and risk losing focus or causing fatigue. The answer, ultimately, depends on several factors such as the size of the team, the complexity of the project, and the specific goals of the retro. A good starting point might be to aim for a duration of 30 minutes to an hour, but be prepared to adjust based on the needs and dynamics of your team.
