There's certainly no shortage of software design methods: most demand total allegiance, and many claim to be the only true way to delivering useful and maintainable software systems in a timely manner. Contextual Design
describes another worthwhile software engineering method, one that places the user (or customer) at the forefront of the software design process from beginning to end. This method seems to be a particularly worthwhile addition to the literature.
Contextual Design begins with contextual inquiry, where software developers interview users and attempt to understand the way they work. Such "customer empathy" is central to the Contextual Design process and a total understanding of "work" within organizations is the mantra here. The book describes how, later in the process, software developers step back from the user data and do an "affinity," which is an overall analysis of hundreds (or even thousands) of individual facts. Contextual Design then explains the additional steps required to build systems using this method, including building models for flow, sequence, and artifacts, and establishing the cultural and the physical environments for a system. After getting an overview, developers consolidate these initial models, get more user input, and then design user interfaces.
This book, written in a clear, informal style without excessive jargon, reads very much like a book on business motivation. Various practitioners of Contextual Design offer short testimonials on the software design method.
"If necessity is the mother of invention, then if you don't know what the users need you can't invent. Karen and Hugh present a step-by-step way to uncover, understand, and use those needs. If developers are not already using techniques like those presented here, they should read this book carefully to see what they are missing."
--Dan Bricklin, co-creator of VisiCalc
"Hugh Beyer and Karen Holtzblatt are widely recognized as the foremost experts on contextual inquiry, and they have packed what they know into a book of both substance and intelligence. It has been a long wait but worth it. The book lucidly shows how to capture the real requirements of customers and how to tailor designs to fit their needs. If you care about your customers and want to create products they as well as want, then you need to understand contextual inquiry and contextual design. You need this book."

"For many years, Beyer and Holtzblatt have been pioneers in the field of human-computer interaction, showing how the context of computer use can be (and needs to be) the central focus of analysis and design. This book conveys the understanding and wisdom that they have gained from their experience in contextual design in a form that is accessible to students and design practitioners. It will serve as a guide and handbook for the next generation of interaction designers, and as a result we can expect the usability and appropriateness of computer systems to be greatly improved."
