Estudo comparativo entre técnicas de inspeção de usabilidade sobre diagramas de atividades

The goal of this paper is to compare the performance of two usability inspection methods that aim at anticipating the evaluation process by inspecting Activity Diagrams. In order to achieve this goal, we carried out a feasibility study by following an established inspection process. According to quantitative results, the Usability Guidelines method outperformed the MIT 3 with regards to efficacy and had similar performance regarding efficiency. However, through a qualitative analysis, the MIT 3 was considered easier to remember and to learn and also more useful than the Usability Guidelines. We found out that the Usability Guidelines method could be used for more experienced professionals on usability issues and perhaps has an even better performance. Notwithstanding, the MIT 3 method could be suggested for the use by a little less experienced professionals with regards to usability issues, supporting the formation and training of design and development teams.
