One of the recommended practices for Scrum Masters/Team Coaches when facilitating Iteration Review is to begin to consider how and what to demo in Iteration Planning. This helps the team to have a clear vision of the expected outcome and to align their work with the iteration goals. It also facilitates the preparation and execution of the demo, as the team can anticipate the feedback and questions from the stakeholders.
