"HCI professionals will repeat quotes with statistics, learn from case studies, and copy chapters for their managers. Thorough & thoughtful, practical & actionable-- readers will be able to put the ideas to work immediately!" —Ben Shneiderman, University of Maryland "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." —Dominick J. Dellino, Director of User Research and Testing, Washington Mutual
You just know that an improvement of the user interface will reap rewards, but how do you justify the expense and the labor and the time—guarantee a robust ROI!—ahead of time? How do you decide how much of an investment should be funded? And what is the best way to sell usability to others? In this completely revised and new edition of Cost-Justifying Usability, Randolph G. Bias (University of Texas at Austin, with 25 years’ experience as a usability practitioner and manager) and Deborah J. Mayhew (internationally recognized usability consultant and author of two other seminal books including The Usability Engineering Lifecycle) tackle these and many other problems. It has been updated to cover cost-justifying usability for Web sites and intranets, for the complex applications we have today, and for a host of products—offering techniques, examples, and cases that are unavailable elsewhere. No matter what type of product you build, whether or not you are a cost-benefit expert or a born salesperson, this book has the tools that will enable you to cost-justify the appropriate usability investment.
