Title: Good thought work and methodology - An important read
Review: Alan Cooper, as seen in previous books, is able to get to the crux of the problem. If you can get past his self promotion, the book offers some helpful insights into process that I know I will be able to use in future designs.The biggest problem I see is that he doesn't offer any statistical evidence to back up anything he has done. His case studies represent interesting situations that look like there has been a drastic improvement in usability and usefulness. But how much of a change was it really? I'd like to know that compared to the original design, 45% of the users were able to complete the job faster, etc.
