The book takes the reader through the process using the app to illustrate the steps in the process: Research, Insight, Concept and Design. Throughout she provides sage advice on when to delve deeper and when to let it go. She also focuses on behavior and behavior change. A quote from page 125:
Based on what we know about the users and the environment, what does a [new way of living and behaving] look like?This illustrates the constant strong emphasis on behavior change and not just cranking out an app. The book is lavishly illustrated and I do recommend it highly especially for folks interested in usability or in their early years. Do not get it if you want a comprehensive survey of Usability. Do get it if after reading the comprehensive books listed above you want to then actually focus on usability in your next project.
Bottom line is that I do highly recommend it. In fact, I am going to use it in my HCI class in 2014.
