Acesso em: 05 dez. 2023.https://repositorio.ufrn.br/handle/123456789/57340The development of user-centered systems has become increasingly relevant in the digital context. Providing interfaces that reduce the amount of work and increase users’ efficiency is currently a latent premise. This paper addressed the improvement of the interface and its ergonomics for the web system Retratos da Atenção Primária à Saúde. Its main objective is to meet the demand of the research project developed by the Núcleo Avançado de Inovação Tecnológica (NAVI) and to provide transparency to the data related to the Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) of the Federal Government. Nielsen’s usability heuristics and ergonomics for digital interfaces were used to support the quality of the project. The improvement of the interface took place gradually throughout the stages of the project, with the inclusion of new features demanded by the General Coordination of Monitoring and Evaluation, related to the Department of Primary Care of the Ministry of HealthErgonomiaHeurísticasGestão em saúdeAtenção primária à saúdeUsabilidadearticlehttps://doi.org/10.18816/r-bits.v10i2.23967
