A Practical Guide to Usability Testing

I am one of the authors of this book. Courney wrote the anonymous review, icepixy, about her perception of my teaching, which is inappropriate for a public review of a book. Note that her rating is two stars different from the other ratings. Joe Dumas

These folks know usability testing; they have a lot of experience with a wide variety of systems. Their backgrounds in linguistics and in psychology inform their process making it a highly effective and very user-centered process. This book is easy to follow and comprehensive. A great first read or refresher for any usability engineer.

This is a classic in the field, written by two highly-respected usability specialists. I was fortunate to read it as one of the textbooks in a class on usability testing taught by Dr. Dumas. It is a very practical book, covering planning, testing, and reporting the results. The strengths and weaknesses of usability testing are discussed, and there is some information about other usability evaluation methods and basic design principles.This is a republication, with only slight changes, of the 1993 edition, so the technology and costs are not up to date. But it's not hard to think in terms of digital cameras instead of videotape.Highly recommended.

This is required reading for usability professionals. It's a detailed look at testing, covering everything from test plans and lab construction to data analysis and how to handle unqualified testers who slip through the screening process. It covers lower-budget tests in addition to full-scale ones. It's clear that Dumas and Redish have loads of experience, and they're not shy about sharing it.The most useful idea I came away with is that testing needs a specific purpose. You can't just test a system's usability; you test, for example, the navigation system or a membership form.The only flaws here are a couple of omissions. There's no mention of testing web applications, though the principles covered here can be extrapolated to other purposes. And there is no mention of the ultra-cheap guerilla testing tactics. I doubt Dumas and Redish would approve of them, but it would have been very helpful to read about where these alternative methods were effective and not.This book is a keeper. While my organization will not likely be doing full-blown usability testing for awhile, I'm now more able to evaluate and communicate with third-party testing facilities. And this book will influence all of our other evaluation and assessment testing methods.

This is a step-by-step quide with checklists, offering insight into every stage of usability testing. It should help any software development project produce more usable software (assuming the developers are willing to make changes based on the results of testing).As someone who has done research about usability, taught about usability to over 1000 practitioners, and developed usable systems (some more so than others) for 20 years, I am still impressed every time I open this book. I recommend it as the best practical book on developing usable software (although I also recommend other books, such as Nielsen's "Usablity Engineering" and Rubin's "Handbook of Usability Testing").
