Abstract:

Everyone knows by now that they should test the usability of their applications, but still hardly anybody actually does it. In this article I'll share some tips I've picked up for doing usability tests quickly and effectively. Relatively recent tools like Django and Ruby on Rails allow us to develop projects faster and to make significant changes later in the project timeline. Usability testing methods should now be adapted to fit this modern approach to development.
