Evaluator self-efficacy analysis in a usability test
Andressa Cristina dos Santos, Taffarel Brant-Ribeiro · 2019
When software is made available to users, it is expected to be free of faults and good in quality. Tests such as usability can be employed to contribute to their quality. In such cases, it is possible for evaluators to analyze interfaces and note which usability errors should be corrected. Also, according to the belief of self-efficacy, those who think they are more experienced should find more errors. In this context, the purpose of this study was to perform a usability test with evaluators to verify if those considered to be more experienced were able to find more errors. A self-assessment form and a usability test were applied for this purpose. For each of the nine participants, their experience information along with the usability errors encountered by them were collected. As a result, those who thought they were capable of finding most of the errors did not match those they encountered.
