↪ Replying to @mazemilian
@mazemilian I agree. There is a law of diminishing returns in more tests. But: does a "usability test" mean that I am testing 1 feature or 20 features?
@mazemilian By relying on rules like this I believe orgs are testing with too few target groups and not repeating studies often enough.
@mazemilian Because of course the usage obstacles will change not only when redesigning but also by external factors.
