Abstract
Usability testing of software products is of key importance nowadays. In order for
usability testing to have the desired effect, the appropriate testing methodology must
be chosen. Usability testing can be carried out using qualitative or quantitative
methods. A widely used qualitative method today is the heuristic evaluation proposed
by Jacob Nielsen. However, there are other testing methods such as cognitive
walkthrough or collaborative testing (proposed by Josef Pavlicek and R. Bock).
Although heuristic analysis has generally received a lot of attention in the current
literature, it is important to put the other methods in the right light. These provide a
significantly better view of the user
’
s passage through the interface under test. The
methods better simulate the environment in which the final UI will operate. The user
experience (UX) is then significantly better measurable if the participant goes through
the test scenario in a cognitive (i.e., mental model-defined) way, rather than by mere
heuristic evaluation. A significant milestone is then the cognitive-collaborative pas-
sage, where the collaborative element of the evaluators contributes to the evaluation
of the solution.
