These words sum up the essence of prototyping: the process of generating things that help us get closer to solutions. According to the d-School at Stanford, a prototype can be "anything a user can interact with--be it a wall of post-it notes, a gadget you put together, a role-playing game, or even a storyboard."
Our prototypes range from complex systems, to books, to games. Take a look at the prototyping process, from Minneapolis to Nairobi!
