What is one way to ensure a team is holding successful Iteration Reviews and demos?

One way to ensure a team is holding successful iteration reviews and demos is to have the team demo working, tested system components that meet the definition of done (DoD). This shows the team’s progress and value delivery, and allows them to receive feedback from the product owner and other stakeholders. The team should minimize the use of slides and the preparation time for the demos, and focus on the solution instead of the presentation. The team should also discuss the impact of the current solution on the nonfunctional requirements (NFRs) and identify any risks or impediments.
