Much as we hate to admit it, most prototyping practice lacks a sophisticated understanding of the broad concepts of prototyping -- and its strategic position within the development process. Often we overwhelm with a high-fidelity prototype that designs us into a corner. Or, we can underwhelm with a prototype with too much ambiguity and flexibility to be of much use in the software development process.
This book will help software makers -- developers, designers, and architects -- build effective prototypes every time: prototypes that convey enough information about the product at the appropriate time and thus set expectations appropriately.
This practical, informative book will help anyone -- whether or not one has artistic talent, access to special tools or programming ability -- to use good prototyping style, methods and tools to build prototypes and manage for effective prototyping.
