Over at A List Apart, Robert Hoekman Jr. has written an article, “The Myth of Usability Testing,” which argues that usability evaluations are good for many things, but determining a team’s priorities is not one of them. The Molich experiment proves a single usability team can’t discover all or even most major problems on a site. But usability testing does have value as a shock treatment, trust builder, and part of a triangulation process. Test for the right reasons and achieve a positive outcome.
