Abstract:
Dashboards are used to organize and display important information in a way that must be well-arranged, understandable and easy to read. Thus, the success of the dashboard depends on its usability. In this paper, we present the design and usability evaluation of a dashboard developed for the visualization of system trustworthiness properties, the relationship among them and their relevance in the composition of a trustworthiness score over usage time. The evaluation was performed to understand and support the usability regarding human perception in its operation. Security and Information Technology (IT) specialists feedback was sought throughout the process and was obtained from a usability testing and a questionnaire for user interaction satisfaction. Results revealed usability concerns regarding design and content, which led to improvements that were implemented in the dashboard.
