Sprint Review Meeting
At the end of each sprint a sprint review meeting is held. During this meeting the Scrum team shows what they accomplished during the sprint. Typically this takes the form of a demo of the new features.

The sprint review meeting is intentionally kept very informal, typically with rules forbidding the use of PowerPoint slides and allowing no more than two hours of preparation time for the meeting. A sprint review meeting should not become a distraction or significant detour for the team; rather, it should be a natural result of the sprint.
Participants in a Sprint Review
Participants in the sprint review typically include the Product Owner, the Scrum team, the ScrumMaster, management, customers, and developers from other projects.
Purpose of a Sprint Review
During the sprint review the project is assessed against the sprint goal determined during the Sprint planning meeting. Ideally the team has completed each product backlog item brought into the sprint, but it is more important that they achieve the overall goal of the sprint.
