Written in an engaging style and relevant for any software analyst or designer, Mastering the Requirements Process provides a powerful and useful guide to defining more complete software requirements that lead to better software overall. It's also filled with innovative advice.

The heart of this book is the authors' Volere Requirements Process Model, a step-by-step guide to gathering your requisites. Throughout this book, the authors use this process to explicate a single case study--a system for a municipality that will optimize the de-icing of roadways during snowy weather. Along the way, the book provides a solid guide to identifying and refining requirements, both functional and nonfunctional (such as performance and ease of use).

There are many excellent ideas in the book, including the notion of fitness for your requirements, which can be later used to track whether the software is successful. The book also wisely separates technology from requirements so that analysts can concentrate on understanding and modeling business problems instead of moving right away to the nuts and bolts of implementation. Even if you don't adopt the Volere model in toto, you can benefit from the concepts of "trawling" (a metaphor for the requirements-gathering process), quality gateways (in which tentative requirements are evaluated for inclusion in a project), and the wise use of patterns to help simplify the process.
