"The craft of interaction design is really the craft of creating the models, diagrams and documents that communicate the designer's designs. These representations, and the testing of those with clients and users, are the designer's bread and butter. They are what designers use to do their most important work, moving their knowledge and vision from their minds and hearts to their hands and to the design itself . . . Designers should strive to make each representation a designed artiact, filled with smart, deliberate choices." (Saffer, 119)
