Determine the location and severity of, and list possible design fixes for, each issue.įor about as long as there have been Expert Reviews, there’s been papers asking whether Expert Reviews are a suitable replacement for usability testing:. Identify, based on a set of heuristics (guidelines), known and expected issues.Step through the tasks as users would: know what terms, features, and capabilities they expect, and anticipate what paths they’ll take.A hybrid services of the two methods we use when conducting an Expert Review that’s both efficient and effective is to: In practice, the terms are used interchangeably and the methods are co-mingled. Heuristic Evaluations and Cognitive Walkthroughs are the most popular. There are a number of flavors of Expert Reviews (also called inspection methods). Like a physician who can diagnose an illness without having to run any tests–trained evaluators independently inspecting an interface can uncover many usability problems without having to test any participants. lack of application status (Is the app working? Is it stuck?).confusing error messages (What does that error code mean?).lack of confirmation messages (I clicked did it work? Is anything happening?).poorly labeled functions or menus (Where do I find X? How do I do Y?).Some examples of problems that consistently tend to cause problems for users are That is, despite the many variations in websites, software products, and hardware products, we see patterns across all interfaces. Observing just a few participants attempt actual tasks can reveal a great deal about interaction problems and generate ideas on what to fix.īut if you conduct enough usability tests and observe enough users, you notice patterns in behavior. I write a lot about the value of having actual users attempt tasks in an interface…for good reason. Usability testing is an essential method to measure the user experience.
