Avaliação de usabilidade do módulo de alunos do sistema integrados de gestão de atividades acadêmicas-SIGAA

Abstract

Information systems are essential tools for running a business or organization. With the Development of information technology and the internet, systems have become essential. The system’s interface has a fundamental importance during the user interaction, because it establishes how and what information will be available. In order to obtain a good user experience in the interactive process, it is necessary to build ergonomic interfaces, obeying the needs and profile of users. It is importante these interfaces are evaluated for their usability. This work aims to talk about a usability evaluation of the students module of the Sistema Integrado de Gestão de Atividades Acadêmicas - SIGAA, Universidade Federal do Ceará - UFC. To reach the goals of this work, a research method (questionnaire) was initially applied to identify the main problems faced by the students when using the SIGAA. Through the questionnaire we were able to understand which features the students feel most difficult to use in the system. Then an inspection (heuristic evaluation) was performed at the interfaces of the system to understand why students feel difficulties in using it. After the evaluation process of the interface of SIGAA, we realized that it really presents usability problems, since it presents a large number of violation of Nielsen’s heuristics. We conclude that although the system is not efficient, users are almost never prevented from using it, but the interface design flaws cause frustration to users when using it. We can say that the usability evaluation of a system is extremely important for the improvement of the use and experience of the user.
