This is a quick overview of usability with some jump start “How to improve usability” tips. This is part of Jakob Nielsen’s web usability website, which contains regularly updated articles on usability, including usability testing.

This is an incredible resource for all aspects of usability engineering, including testing. It is almost like a directory within itself as many external references are documented. Mostly the references are academic and not ‘rule of thumb’ type guidance that the casual (usability) application tester might be looking for.
