This presentation was prepared for a free international startup conference at Ravensbourne College, London. This is not an extensive "How To" guide for rapid prototyping, it is more a quick guide to outline why we do it, and to give a quick overview of the process. Mainly: Rapid Prototyping is a great way to battle the human condition: our natural tendencies to spend too much time perfecting an idea or product before launching it; to refine ideas FOREVER, and not test them early enough.
