Freitas, Rayane Kelly de Sousa. Redesign da RTiWIM: uma ferramenta de elicitação e validação de requisitos de software

Abstract

RTiWIM is a tool focused on improving the process of eliciting and validating software requirements through the interface language in existing web systems in order to avoid errors and rework during development. However, during its implementation, there was a priority given to developing functionalities to the detriment of aspects related to interface design, making it difficult for users to use it. Thus, this work aims to identify possible usability problems in this system and propose a redesign of the interface that improves quality and reduces the severity of errors during use. To this end, the work was divided into four stages: discover, define, develop and deliver, in which a usability test was carried out followed by an interview to identify interaction problems, in which we simulated a survey of requirements for improvements in the Integrated Academic Activities Management System (SIGAA). In addition, a heuristic inspection was carried out to identify problems in the interface. Based on the data obtained, a solution proposal was made, which was materialized through a high-fidelity prototype, which was later validated through a usability test. The results obtained showed that the proposed solution improved the usability of RTIWIM, making it more intuitive and efficient for users.
