Product Description

Delivering the software that your customer really wants.

"Mastering the Requirements Process and the Volere specification template are real breakthroughs. They introduce the beginnings of science to a domain which had, up till now, been ruled by craft." - Tom DeMarco

It is widely recognized that incorrect requirements account for up to 60% of errors in software products, and yet the majority of software development organizations do not have a formal requirements process.

Many organizations appear willing to spend huge amounts on fixing and altering badly-specified software, but seem unwilling to invest a much smaller amount to get the requirements right in the first place.

This is a book for those who want to get the right requirements.

Mastering the Requirements Process sets out an industry-tested process for gathering and verifying requirements. It provides the techniques and insights for discovering precisely what the customer wants and needs.

"Mastering the Requirements Process shows, step by step, template by template, example by example, one well-tested way to assemble a complete, comprehensive requirements process." - Jerry Weinberg

The specification template in this book provides the basis for your own requirements specifications. It guides you to the correct specification content as each part of the process reveals different aspects of the products functionality and properties.

This book shows you how to make the requirement measurable and testable. By providing a measurement - a fit criterion - for each requirement, the requirements analyst can describe precisely what the customer wants, the designer can construct a product that exactly matches the requirement, and the tester can determine whether or not the final solution satisfies the requirement.

"The Robertsons' concept of fit criteria is -- all by itself -- worth the investment of your time to read the whole book. Fit criteria and the allied discipline of quality gateways enable you to build requirement sets that are measurable, provably correct and testibly complete." - Tom DeMarco

Amazon.co.uk Review
Written for any software analyst or designer, Mastering the Requirements Process provides a powerful and useful guide to defining software requirements that are more complete and lead to overall better software. Written in an engaging style and filled with innovative advice, this book can help anyone who designs software for a living.

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 optimise the de-icing of roadways during snowy weather. Along the way, this book provides a solid guide to identifying and refining requirements, both functional and non-functional (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 software is successful. The book also wisely separates technology from requirements so that analysts can concentrate on understanding and modelling business problems instead of moving right away to the nuts-and-bolts of implementation. Even if you don't adopt the Volere model, any software designer 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.

Anchored by numerous examples (including many samples of successful requirements), the book provides an appealing mix of new ideas along with a remarkably clear presentation. In short, Mastering the Requirements Process provides useful advice that can make the project specification building phase of the software process easier and more robust. It provides the first steps for improving overall software quality for your organisation. --Richard Dragan, amazon.com

Customer Reviews

This gives the vital "how"
This book emphasises the rigour, evolutionary nature and structure of requirements. For those in a rush, the book has a very brief and useful summary at the end of each chapter. The Requirements Specification Template is at the heart/brain of this book. The template includes the Requirements Shell, which is filled-in for each individual requirement. The book explains the processes involved in producing the template. Requirements are structured in a very holistic manner and they have the concept of "potential requirements"; requirements are not real until they have passed through the Quality Gateway. On the downside, the book seems rather lengthy with much repetition but is worth its weight in gold for the Appendices: A "A Volere Requirements Process Model", B "Volere Requirements Specification Template". Also, the practical experience and humour of the authors shine through. Note: "Volere" is the Italian word for "to wish" or "to want".

A gem in an under-published subject
I'd never read a book on 'business analysis' or 'requirements engineering' before. I've never studied computer science either. But I have been a business analyst for the last few years -- helping clients define their requirements, improve processes and build solutions.

"Mastering the Requirements Process" is an enlightening read. The Volere requirements engineering process is well structured, and documented in some detail. I also enjoyed the use of a UK case study, even if the language used was American English. The authors introduce an array of terminology, mostly accepted terms coined by other authors, but Robertson & Robertson's definition of terminology like 'use cases' was slightly fuzzy for someone new to requirements engineering. However, Robertson & Robertson do provide plenty of recommended reading (and even more reasons to use Amazon.co.uk). They also provide a useful website with templates and updates.

I would have given it five stars, but I think coverage of business events, use cases and inputs/outputs could have been better, and the writing could have been more concise in places.

IThis is very very good stuff
This is just a gem. If you've never read anything else about requirements, start here, and when you have widened your reading,you'll still find yourself stuffing it into your bag to re-read a half-remembered chapter on the train, months or years later. Of all the requirements books this is the one that I come back to for basic common sense. It's really about software challenges, but you can extrapolate the techniques to other fields; I just wish they'd write some more stuff like this for goofball systems engineers trying to mix up software, hardware, processes and people in complex supply chains. Then I'd be in systems heaven! Their other book is great too. (They should pay me for this copy)
