Usability testing is a key activity for measuring efficiency,
effectiveness and satisfaction of users interacting with a software.
As suggested by literature, usability testing should involve a
representative sample of the user population in order to obtain a
comprehensive insight and meaningful feedback. But how do different
user profiles relate to the type of outcome provided in these tests?
How do different levels of system expertise affect users' feedback?
How in regards to domain knowledge? This thesis aims to study the
effect of different factors on the outcomes of usability testing,
namely: design version, system expertise and domain knowledge. A
two-design experiment is studied on two different user population with
different levels of domain knowledge and system expertise on the
tested designs. The data gathered from testing with 50 users is used
to analyze the effect of the three factors mentioned above on the
outcomes of usability testing.
