"Cost-Justifying Usability" delivers much more than the promise of its title. Each chapter is worth the price of admission! I found more useful ideas and creative thinking in this book than I've come across in one place in years. Moreover, the collection of articles goes far beyond what the book title might suggest: it not only offers the definitive treatment of determining ROI for usability, but also provides a complete overview of usability considerations for getting you there. From specific calculations to help you with extending the business case, to introducing ethnography into the product development process, Cost Justifying Usability offers a treasure of gems for every user-centered design professional.
