I have to say, on the whole I was actually pretty disappointed in this book. It came off frustrating, I think, partly because there was no cohesive voice. Usually, one would say this is indicative of the design research community as a whole, but I found myself having a hard time switching from topic to topic so fast - the essays were pretty short, and as such, didn't contain a whole lot of information and/or depth to them. The most disappointing section, to me, was the first on "People," because while this is one of the topics (ethnography and the study of people) that I'm most interested in, the essays only seemed to wade into the area knee-deep. That said, there were a few interesting gems in the "Process" section, especially Sean Donahue and Eric Zimmerman's essays. But in reality, I'd pass the book up for a book that more consistently and deeply approaches the topic of design research.
