Sprint Reviews and Sprint Retrospectives: What’s the difference?
Sprint reviews take place after the sprint goal has been met, and before the next sprint planning session. The goal of each sprint is usually a functional increment, or deliverable. People who should attend these meetings are the stakeholders, Scrum Master and team, and the product owner. These meetings shouldn’t be any more than 4 hours, to keep them from being tedious. 2 to 3 hours should be enough to cover all the relevant topics.
