Advice from the experts on how to justify time and money spent on usability!

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. Includes contributions by a host of experts involved in this work, including Aaron Marcus, Janice Rohn, Chauncey Wilson, Nigel Bevan, Dennis Wixon, Clare-Marie Karat, Susan Dray, Charles Mauro, and many others Includes actionable ideas for every phase of the software development process Includes case studies from inside a variety of companies Includes ideas from "the other side of the table," software executives who hold the purse strings, who offer thoughts on which proposals for usability support they've funded, and which ones they've declined

This text is about achieving usability in product user interface design through a process called Usability Engineering. The techniques presented include not only UI requirements analysis, but also organizational and managerial strategies.

This completely revised edition, of the Handbook of Human-Computer Interaction, of which 80% of the content is new, reflects the developments in the field since the publication of the first edition in 1988. The handbook is concerned with principles for design of the Human-Computer Interface, and has both academic and practical purposes. It is intended to summarize the research and provide recommendations for how the information can be used by designers of computer systems. The volume may also be used as a reference for teaching and research. Professionals who are involved in design of HCI will find this volume indispensable, including: computer scientists, cognitive scientists, experimental psychologists, human factors professionals, interface designers, systems engineers, managers and executives working with systems development. Much of the information in the handbook may also be generalized to apply to areas outside the traditional field of HCI.

Due to the ever-changing technological landscape and the global integration of the Internet in schools, libraries, homes, and businesses, the content of this second edition changed significantly. Since many computer users are connected at both home and work, the Web has transformed communication; consumption patterns; and access to business, politi
