When you test the second user, you will discover that this person does some of the same things as the first user, so there is some overlap in what you learn. People are definitely different, so there will also be something new that the second user does that you did not observe with the first user. So the second user adds some amount of new insight, but not nearly as much as the first user did Jakob Nielsen, Ph.D., is a User Advocate and principal of the Nielsen Norman Group which he co-founded with Dr. Donald A. Norman (former VP of research at Apple Computer).

Based on the studies he and Landauer conducted, Nielsen argued that the number of usability problems found in a test decreases after the fifth user. This rule was based on the Law of diminishing returns set forth by Virzi (1992) Beim In-Store-Test nach Jakob Nielsen testet der Testleiter im Ladengeschäft des Kunden einen Papierprototypen oder Klick-Dummy der Website mit fünf zufällig anwesenden Kunden als Probanden. Bei Remote-Usability-Tests wird der gesamte Prozess des Usability-Tests online abgewickelt. Man verzichtet darauf, Probanden lokal zu rekrutieren und diese in ein Labor oder das eigene Büro einzuladen. In der Regel werden diese Tests über einen spezialisierten Anbieter durchgeführt, der.

Sadly, few projects collect such user testing metrics because doing so is expensive: it requires 4 times as many users as simple user testing. Nielsen is of course referring to the difficulty and cost associated with quantitative testing versus qualitative testing. However, technology in 2006 (the year of his study) is not comparable to the technology of 2019. With contemporary usability testing platforms such as TryMyUI It is worth noting that Nielsen does not advocate stopping after a single test with five users; his point is that testing with five users, fixing the problems they uncover, and then testing the revised site with five different users is a better use of limited resources than running a single usability test with 10 users

For Usability Testing: If you follow Jakob Nielsen's advice: test with 5 users or less (2 users for low-fidelity prototypes) and do many iterations of testing (at least 3 rounds of testing).
