SIGFinder - Repositório online de gráficos de interdependência de softgoals

Abstract

Non-functional requirements have a direct impact on the quality of developed software. In so doing, developers need to strive to reach the RNFs that are needed to deliver the required software with quality. RNFs are global in nature, so as developers strive to reach the application’s RNFs, conflicts and synergies can occur between them. To assist them in existing trade-offs, the team responsible for such activity can make use of knowledge stored by third parties, thus saving time, cost and effort. This stored knowledge is usually represented graphically, in the form of Softgoal Interdependency Graphs (SIGs). However, these catalogs are scattered in various databases and books, the search for which is expensive. In order to solve the problem addressed, the present work presents a tool, called SIGFinder, where these catalogs are categorized and made available to the developers, thus saving the search time that would be necessary to find them. Through a usability test, the application was evaluated by users who did a set of proposed tasks. The results of this test showed a good level of participants’ satisfaction with the application, as well as a good level of ease in carrying out the proposed activities. It is concluded that the repository is able to store and make available, and to show users the catalogs of RNFs. In addition, an internal quality assessment of the code was also performed, which indicates that the application has few vulnerabilities.
