How many participants is enough for user testing?
Summary: Elaborate usability tests are a waste of resources. The best results come from testing no more than 5 users and running as many small tests as you can afford.
What are two ways to test information architecture?
The two main ways of running this type of usability test are face-to-face or online (yes, you can do both).
Why you should test with 5 users?
In a research study from 2000, Jakob Nielsen and Tom Landauer found that you only need 5 users to test your application in order to identify 75-99% of all usability problems. You only need 3 to 5 users to identify the majority of usability issues.
What's the bare minimum number of users needed to run a successful design test?
Before you move into testing, you'll need users. Aim to grab 5–10 users at a bare-minimum per round of testing, but don't go overboard as you'll more than likely be testing over multiple rounds.
