As a registered member of SearchSoftwareQuality.com, you're entitled to a complimentary copy of Chapter 3 of Effective Prototyping for Software Makers written by Jonathan Arnowitz, Michael Arent and Nevin Berger, and published by Morgan Kaufmann, a division of Elsevier.
In "Chapter 3, Verify Prototype Assumptions and Requirements," the authors explain how to transform assumptions into validated requirements through a process of six iterations.
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.
