Uma análise comparativa dos métodos de avaliação de sistemas colaborativos fundamentados na engenharia semiótica

Collaborative systems are growing more and more popular. However, evaluating this type of systems is still a difficult task. Many evaluation methods have been proposed to deal with this challenge, but most of them are not yet consolidated. Semiotic Engineering is an explanatory theory about HCI that proposes three different methods that can be applied to evaluate collaborative systems: MIS, MACg and Manas. The goal of this paper was to compare these three methods in order to identify the differences in the results each of them generates. To do so, a case study applying each of the methods was performed. The problems identified with each method were then classified according to a set of criteria we have defined to this end. Based on the classification of the problems, we analyze and discuss the differences in focus of the methods.
