In this paper we highlight four facets of interactive prototypes in user-centered design approaches. After reflecting on their established role in the design and validation phases, we consider recent innovative uses of prototypes in communicating with development/bidders and also to enhance training. To illustrate our experiences, we draw upon a recent successfully completed redesign project in the field of electrical engineering.
