Praise for Moderating Usability Tests
Interacting with participants in a calm and neutral manner may well be the most diffi cult
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 discover-
ing problems or getting ideas about solutions, bias or validity, throw-away data versus
generalizable insights, often depends on the soft skills—the ability to effectively moder-
ate testing. In the past, you were expected to get these skills through apprenticeships or
trial and error. Moderating Usability Tests 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 fi rst time, people newly charged with evaluating products,
and even old hands looking to refi ne and improve their technique.
—Arnold (Arnie) Lund, Director of User Experience, Microsoft
You may not think that being a “Gracious Host” is among your assignments in moderat-
ing a usability test, but you will learn why this and other roles with similarly illuminating
names are important to your success. In this generous book, Dumas and Loring give the
benefi t of their decades of experience and astute observation of both the foundational
and the subtle aspects of conducting usability tests. Many questions you didn’t think to
ask until you were on the hot seat are answered here, and will help you achieve a level
of confi dence as a test moderator that may have seemed beyond reach, even if your par-
ticipants are from challenging-to-test populations. With this highly ethical and thor-
oughly grounded program for developing moderator skills and avoiding pitfalls, Dumas
and Loring make a strong contribution to the body of knowledge on testing products.
The big surprise of the book is that their clear, reasoned, and detailed suggestions about
interacting with test participants and developers will likely spill over and improve your
relationships with coworkers, family, neighbors, and friends.
—Elisabeth Bayle, Bayle Collaborations
At this point, virtually everyone in the software industry knows what usability testing is.
An unfortunate side effect of this awareness is that many people are conducting usability
testing who have no idea how to do so in a way that will yield valid, reliable, and useful
data. Other than the design of the test itself, proper and effective moderation of test
sessions is one of the most important—and least understood—aspects of usability testing.
Here is a book by two highly regarded experts that covers this topic thoroughly in a very
readable format. No one who has not already been well trained should attempt to
conduct usability testing without fi rst reading this book cover to cover, and viewing all
the excellent videos the authors provide on the book’s web site.
