De Usability (en vooral de statistics erachter) expert Jeff Sauro legt hier even heel mooi uit wanneer dat 5 users voldoende zijn.
Kort door de bocht:
– Ja: voor veel gemaakte fouten
– Nee: voor minder voorkomende fouten.
“The best strategy is to bring in some set of users, find the problems they have, fix those problems, then bring in another set of users as part of an iterative design and test strategy. In the end, although you’re never testing more than 5 users at a time, in total you might test 15 or 20 users. In fact, this is what Nielsen recommends in his article, not just testing 5 users in total. “
Test early. Test often.
