The Iteration Review is a cadence-based event, where each team inspects the increment at the end of every Iteration to assess progress, and then adjusts its backlog for the next iteration – ScaledAgileFramework.com

Iteration Review has the potential to be a great source of learning and feedback for all involved. Agile teams embrace the notion of inspect-and-adapt as a MEANS to continually build learning and improvement in how they work. The goal of the meeting is to CREATE visibility around what occurred in the course of the iteration and to amplify learning about what could then be planned for the next iteration. The delivery team presents the done items in a demonstration. Done items are all items that have been accepted by the product owner. 

The demonstration INVITES clarification, reflection, and celebration with regard to the team's commitment. At the end of a GOOD meeting, all attendees have a clear understanding of the completed iteration as well as a good sense of the value that was delivered. The iteration review starts by GOING over the Iteration Goals and talking over their status. It then continues with a walk-through of all the committed stories. Each accomplished story is demoed. The Iteration review is followed by the Iteration Retrospective.
