Proposta de uma ferramenta web para assistência à modelagem de requisitos não funcionais de software

Abstract

A software development project must satisfy objectives (quality, performance, environment and others) that are usually modeled as Non-Functional Requirements (NFR). NFRs are not related to the specific functions offered by the software, but to its properties, such as reliability and response time. The general objective was to develop a web tool, called SIGSoft 1.0, to help a software designer to model their NFRs through softgoals (SIGs) inspired by the NFR-Framework, helping them to predict if there will be influences between them during the modeling process. In this way, the present work was intended to solve the main gaps in tools involving the NFRs available on the market and to provide a library of models for reuse. Based on these objectives, together with the elaboration of the tool, test periods were carried out with TI students (information technology), with the intention of efficiently developing the proposed tool. Regarding the theoretical basis of this research on Requirements Engineering, Functional Requirements, Non-Functional Requirements and System Modeling, we used the studies of Sommerville (2011), Novais (2019), Pressman (2011), Andrade (2019), in addition to other scholars. Thus, by bringing these issues to the center of discussions, it provides an assessment of the current market scenario regarding Non-Functional Requirements modeling tools. It also allows new tools used in the modeling of NFRs through SIG to be developed, using the tool proposed in this work as a basis.
