With a foreword by Steve Krug, author of Don't Make Me Think. "What makes so many products so difficult for the average person to use?" Carol Barnum posits this question in her introduction to this book. Too many perfectly functioning products are being returned because they are not usable. Strong usability testing is the key. But what do we do if under a strict budget and time constraints? How do we properly prepare, test, analyze, and measure across a multitude of cultures, generations, and countries? There are many different testing methods and numerous situations in which to test; however, all are grounded in the same basics of usability testing. Usability Testing Essentials presents a practical, step-by-step approach to learning the entire process of planning and conducting a usability test. It also explains how to analyze and apply the results and what to do when confronted with budgetary and time restrictions.
