"Carol Barnum has done a wonderful job of distilling her research, consulting, and teaching experience into this very lively, practical book on how to do usability testing. You get up-to-date, step-by-step help with lots of variations to suit your own situation. You see each part in action through the running case study. If you have a global market, you'll especially want the chapter on international usability testing. This is a great addition to the usability toolkit." ---Janice (Ginny) Redish, Charter member of the UPA, author of Letting Go of the Words: Writing Web Content that Works "Carol is a rare breed, both an academic and a practitioner. Her voice of experience comes across clearly, backed by references that illustrate where and who our methods came from. Newcomers to usability testing will find a solid introduction; while those more experienced will find unexpected insights into the field."---Carolyn Snyder, Snyder Consulting "What makes so many products so difficult for the average person to use?"
