i finally read Donāt Make Me Think (~revised~), which i feel i should have read many years ago. the whole thing is meaty, but here were my favorite parts, cherry-picked and in no particular order:
In general, I think itās safe to say that users donāt mind a lot of clicks as long as each click is painless and they have continued confidence that theyāre on the right track ā following whatās often called the āscent of information.ā Links that clearly and unambiguously identify their target give off a strong scent that assures users that clicking them will bring them nearer to their āprey.ā Ambiguous or poorly worded links do not.
Some people will complain that three [participants for a user test] arenāt enough. Theyāll say that itās too small a sample to prove anything and that it wonāt uncover all of the problems. Both of these are true but they just donāt matter, and hereās why:
The purpose of this kind of testing isnāt to prove anything. Proving things requires quantitative testing, with a large sample size, a clearly defined and rigorously followed test protocol, and lots of data gathering and analysis.
Do-it-yourself tests are a qualitative method whose purpose is to improve what youāre building by identifying and fixing usability problems. The process isnāt rigorous at all: You give them tasks to do, you observe, and you learn The result is actionable insights, not proof.
You donāt need to find all of the problems. In fact, youāll never find all of the problems in anything you test. And it wouldnāt help if you did, because of this fact:
You can find more problems in half a day than you can fix in a month.
