Test the prototype with real live humans, and validate. The team finally gets to see live users interact with their idea,s and hear direct feedback from the target audience. Everyone on the team observes the Validation sessions: watching your users try out the prototype is the best way to discover major issues with your design, which in turn lets you start iterating immediately. In addition, the team can organize a review to collect feedback from Technical Experts or Leadership Stakeholders.
