reviews and tests are complementary rather than substitutes.
a usability review can uncover many usability issues without
having to test any participant. it can quickly cover different
sections of a website, scenarios and tasks. a usability review
also helps where usability tests can’t solve a particular set of
problems. but...
a usability review doesn’t actually tell you how usable a website
is, just how usable it should be. a usability review is subjective
and doesn’t uncover all the issues. and it cannot provide the
critical hard data to support design decisions as usability tests
do.
