Benchmark usability testing is very different from conventional usability testing. First, participants don’t come to a lab instead, the participant carries out the test from his or her home or place of work. Second, a moderator does not interact with the test participant instead participants work with an automated system that asks them to perform tasks, measures their performance and asks for subjective comments. If you would like to see benchmark usability testing in action, you can take a tour from the perspective of a test participant. You can also view a sample report from a benchmark usability test (pdf format).
