To Jack, the one and only
In 2008, I decided to put together a panel at the annual conference of the Usability Professionals Association. The topic was Discount Testing by Amateurs: Threat or Menace?
At the time, I was about to go out on a limb by writing a book based on the premise that everyone involved in creating websites should be doing their own usability testing.
Not surprisingly, the idea of amateurs doing the work of professionals was viewed by some members of the usability community as a potential threat to full employment and high standards, although these concerns were rarely discussed in public. So I thought it would be a good idea to bring the debate out in the openpreferably before I spent what promised to be a painful year writing my book.
Randolph Bias kindly agreed to take the contrary position (Testing by amateurs is a very bad idea for many reasons), but we needed someone to sit in between us and argue for a sensible, balanced viewpoint. It had to be someone very smart, with a lot of credibility in the profession. I immediately thought of Carol Barnum.
To help people get in the spirit of the thing and hopefully take sides, we even made up a series of buttons with inflammatory phrases like Steve, you ignorant slut! and Randolph, you ignorant slut!. Carols button was easy to write.
Even though I have had the pleasure of knowing Carol for more than a decade, I think I first started thinking of her as the voice of reason in 2002 when I read a paper she had written about one of the perennial questions in our field: How many participants do you need in a usability test to discover most of the problems?In it, she took an argument that threatened to go on forever and finally made sense out of it, recapping all the research (some of the most insightful of which was done by her own students at Southern Polytechnic), neatly summarizing the various viewpoints, and drawing what I thought were incredibly insightful conclusions.Ever since then, she has been one of my go-to people when I need a sounding board on usability-related issues.
You may be wondering why I am here recommending Carols usability testing book if I just published one myself. But mine is a very short book that only covers the basics of one flavor of testing. I was ruthless in leaving out whole topicsimportant topicsbecause I had a very specific objective: to get people started.But I only felt free to be this ruthless because I knew that once people got a taste of usability testing they would want to know more, and I could point them to books that do go into detail on all the important topics.And even though Carols book was not written yet, I included it in my list of recommended reading anyway (a very short listI only recommend books that I think are excellent) because I knew it would be one of the best.
I am glad its finally here. And I am glad I was right: its excellent.
I knew it would be.
