Absolutely brilliant from start to finish.
This book has some sterling advice, clearly based on real experiences and provides practical solutions to the aspiring UX practitioner, as well as the more experienced professional.
Personally I found the practical tools the most helpful out of any book I've come across. Being able to apply good user experience techniques fits hand in hand with understanding the theories so having some real templates, guides and tools to get others involved in the process of user experience design is incredibly helpful.
Alongside the theories and tools, this book finally provides guidance and advice on getting others involved in the user experience process. These ideas and guides don't just apply if you're working on your own as a freelancer or contractor but work equally well if you're the only person in a team or organisation that seems user experience as something to care about.
Whether you're someone interested in learning more about user experience or already a practicing professional in the field, I highly recommend you get a copy of this book. It's worth more than it's weight in gold.
