Moderating Usability Tests provides insight and guidance for usability testing. To a large extent, successful usability testing depends on the skills of the person facilitating the test. However, most usability specialists still learn how to conduct tests through an apprentice system with little formal training.

This book is the resource for new and experienced moderators to learn about the rules and practices for interacting. Authors Dumas and Loring draw on their combined 40 years of usability testing experience to develop and present the most effective principles and practices – both practical and ethical – for moderating successful usability tests. The videos are available from the publisher's companion web site.

  • Offers targeted advice on how to maintain objectivity

Joe and Beth really know their stuff, and they’ve put together a book that’s enormously valuable for usability professionals and usability amateurs. Whether you’ve conducted hundreds of tests or are about to try your first one, you owe it to yourself--and your team...and your test participants--to read this. - Steve Krug, author of Don’t Make Me Think Interacting with participants in a calm and neutral manner may well be the most difficult part of doing usability testing. Now you no longer have to worry about how to do that. Just follow Dumas and Loring's wonderful, practical advice and you will be prepared not only for typical encounters, but also for the unusual and unexpected, for doing remote testing, and for working with special populations. Moderating Usability Tests is a great resource for anyone who interacts with usability test participants. - Janice (Ginny) Redish, President, Redish & Associates, Inc. Everyone talks about research methods, but the formal aspects of those methods only get you so far. The difference between getting a little data or a lot of data, only discovering problems or getting ideas about solutions, bias or validity, throw-away data versus generalizable insights, often depend on the soft skills, the ability to effectively moderate testing. In the past, you were expected to get these skills through apprenticeships or trial and error. Moderating Usability Tests: Principles for Interacting with Participants removes the mystery and provides practical advice on how to get the most out of research. It will be invaluable to students learning about usability testing for the first time, people newly charged with evaluating products, and even old hands looking to refine and improve their technique. - Arnold Lund, Director of User Experience, Microsoft You may not think that being a “Gracious Host” is among your assignments in moderating a usability test, but y
