Abstract

[context] iStar has been extended to include constructs of a great number of application areas by adding new symbols. We analyzed the existing iStar extensions in a Systematic Literature Review and identified the occurrence of symbol redundancy (constructs represented by two or more symbols) among the existing constructs. The occurrence of symbol redundancy can hinder the usage of these constructs. [objective] We are interested in defining a prioritization of the preferences of these symbols. Thus, we performed a survey with novices to analyze their preferences about the representations. [results] The 83 participants expressed their preferences concerning the most adequate graphical representation for each construct with symbol redundancy. We presented a ranking of the symbols for each concept with symbol redundancy. These results can be useful to extenders to choose the symbols of these constructs when reusing the extensions which propose them.
