Description
Usability Testing Essentials provides readers with the tools and techniques needed to begin usability testing or to advance their knowledge in this area.
The book begins by presenting the essentials of usability testing, which include focusing on the user and not the product; knowing when to conduct small or large studies; and thinking of usability as hill climbing. It then reviews testing options and places usability testing into the context of a user-centered design (UCD). It goes on to discuss the planning, preparation, and implementation of a usability test. The remaining chapters cover the analysis and reporting of usability test findings, and the unique aspects of international usability testing.
This book will be useful to anyone else involved in the development or support of any type of product, such as software or web developers, engineers, interaction designers, information architects, technical communicators, visual or graphic designers, trainers, user-assistance specialists, and instructional technologists.

About the Author

Carol Barnum
Carol M. Barnum, PhD, became a usability advocate in the early 1990s. It happened when she heard the word “usability” at a Society for Technical Communication conference. Technical communicators have always seen themselves as the user’s advocate, but here was an emerging discipline that championed the cause of the user! It was love at first sight. In 1993, Carol attended the second Usability Professionals Association Conference, where she was thrilled to mix and mingle with several hundred usability folks on Microsoft’s corporate campus. Those two conferences sparked a desire to combine her love of teaching students how to be clear communicators with a new-found passion for helping companies understand how to promote good communication between their product and their users. In 1994, Carol opened her first usability lab in a windowless basement location at Kennesaw State University (formerly Southern Polytechnic State University). Throughout her teaching career, she built several more labs, developed a course in usability testing, developed a graduate program in Information Design and Communication, and worked with numerous clients to help them unlock the users’ experience with software, hardware, documentation and training products, mobile devices, web applications, websites, apps, and more. Not one to retire, she left her teaching career in 2013 at the rank of Professor Emeritus to become a fulltime UX consultant, trainer, and speaker. She has traveled the world speaking at conferences and training UX practitioners and students. Recognition for her speaking includes the Presentation Prize at the first European Usability Professionals Association Conference and top ratings at UXPA, STC, and IEEE’s Professional Communication conferences. Carol is the author of five other books and more than 50 articles and book chapters covering a variety of topics, including the state of UX research, UX reporting styles, the impact of Agile on usability testing, the “Magic Number 5” and whether it is enough for web testing, using Microsoft’s product reaction cards for insights into the desirability factor in user experience, storytelling for user experience, and issues affecting international/intercultural communication and design. Carol’s work has brought recognition from the Society for Technical Communication, including the designation of Fellow, the Rainey Award for Research, and the Gould Award for Excellence in Teaching Technical Communication. She also received the Blicq Award for Distinction in Technical Communication Education from the IEEE Professional Communication Society. Above all else, Carol continues to love helping others improve user experience in all aspects of their life.

Reviews
"Beg, borrow, buy or steal a copy of Usability Testing Essentials: Ready, Set…Test! This is as good a book on usability testing as you are going to find, and it will provide practical guidance regardless of your experience level…if you want a single book on usability, a book that will touch upon the primary topical areas in sufficient detail to be useful, Usability Testing Essentials: Ready, Set…Test! by Carol Barnum is the one to read. You won’t be disappointed."--User Experience, Volume 11, Issue 4, 4th Quarter 2012
"Have you been inspired to try usability testing, but not sure exactly how to go about it? Carol Barnum’s book will take you step-by-step through all you need to do. Plus, she gives you a solid background in the context and history of testing – and adds a valuable chapter on international testing. Carol is highly regarded as a teacher, an academic, and a practitioner, and all three of her roles shine through in this book" -- Caroline Jarrett, User Experience and Usability Consultant, Effortmark Limited, author of Forms that Work
"Carol Barnum’s Usability Testing Essentials delivers just what the title promises. Readers who are new to usability studies will find here all they need to know to design and execute a test, analyze the test data, and provide an effective report with recommendations for clients. But even usability experts will find the book chock full of ideas, insights, and suggestions that will improve their practice and their teaching in this increasingly important area of study. Barnum’s expertise on the subject shines through on every page, but the book’s greatest strength is its careful attention to analyzing test results, a topic that earlier texts have tended to gloss over much too quickly." -- George Hayhoe, PhD, Mercer University School of Engineering
"Usability Testing Essentials will guide you through both conducting a usability evaluation and making the decisions that will make it a useful and effective part of any user experience project. Carol Barnum places usability evaluation into the larger context of user-centered design. It is a valuable resource for anyone getting started in usability and a excellent companion to both Letting Go of the Words and Forms that Work."—Whitney Quesenbery, WQusability
"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
