tend to find around 30% of the issues<\/a> uncovered in a usability test.\u00a0 It’s ideal to have more than one Expert Review the interface independently. And while you want experts who are familiar with the domain (e.g. financial software), we’ve found even novice evaluators uncover real problems that more seasoned experts miss.<\/p>\n4.\u00a0\u00a0 \u00a0Expert Reviews find problems that usability testing misses.<\/h2>\n
Just because a problem identified in an Expert Review wasn’t uncovered in a usability test doesn’t mean it’s NOT a problem. In my experience, while Expert Reviews can uncover trivial issues, few are actually not real problems (false positives).<\/p>\n
5.\u00a0\u00a0 \u00a0You can’t justify the cost or time of usability testing.<\/h2>\n
Even if you don’t pay your participants, usability testing has a cost. The fastest usability tests require time for recruiting, time for facilitation, and time for compiling the findings. A typical Expert Review, on the other hand, takes no more than a few hours, start to finish.<\/p>\n
6. A Usability test can’t cover everything.<\/h2>\n
Usability-test participants can attempt only so many tasks on a product in the time allotted. Thus, in many cases, the usability test reveals problems on only a small portion of the interface. Expert Reviews, at less cost, can go wide and deep, uncovering problems throughout the interface.<\/p>\n
Conclusion<\/h2>\n
Expert Reviews aren’t a panacea.\u00a0 They aren’t a full substitute for user testing, but they’re something more than a second-rate usability test. When it’s difficult to conduct a usability test, or where a usability test won’t solve your problems, an Expert Review is often the better tool.<\/p>\n
A thorough review of an interface (ideally by people familiar with the domain), with multiple evaluators, focused on tasks and goals, compared to a set of guidelines, provides quick insight into potential problems and may fix more problems faster than a usability test.<\/p>\n","protected":false},"excerpt":{"rendered":"
Usability testing is an essential method to measure the user experience. I write a lot about the value of having actual users attempt tasks in an interface…for good reason. Observing just a few participants attempt actual tasks can reveal a great deal about interaction problems and generate ideas on what to fix.
