Make models. Pin mood boards. Sketch out the bones of the process in rough wireframes. Write imaginary press releases. Create detailed mock-ups that show how a customer would travel from an ad to the website to the app and what information they would see at each touchpoint. Write up the reactions you’d want to get from early adopters, the headlines you’d want to see from reviewers, the feelings you want to evoke in everyone. Make it visible. Physical.
