The usability of a consumer application was tested in two environments: in a laboratory and in a field with a total of 40 test users. The same problems were found in both environments, differences occurred in the frequency of findings between the contexts. Results indicate that conducting a time-consuming field test may not be worthwhile when searching user interface flaws to improve user interaction. In spite of this, it is possible that field testing is worthwhile when combining usability tests with a field pilot or contextual study where user behavior is investigated in a natural context.
