“When properly carried out, usability reviews are a very efficient way of finding the usability bloopers in an interface. But there are four common mistakes made by novice reviewers: failing to take the user’s perspective; using only a single reviewer, rather than collating the results from a team; using a generic set of usability principles rather than technology-specific guidelines; and lacking the experience to judge which problems are important.”
