This study describes the creation and development of the PUERPERIUM software, which utilizes the General Comfort Questionnaire translated into Brazilian Portuguese and adapted for postpartum adolescents. The software development process followed five steps: (1) requirements elicitation, involving the extraction of functionalities and identification of quality attributes such as usability, reliability, security, and availability; (2) definition of the software project and architecture, including the selection of technologies such as programming languages and services; (3) software implementation; (4) validation, verification, and testing; and (5) deployment. The software development began with identifying the necessary requirements, followed by designing the architecture consisting of the server layer and visualization layer. During implementation, the integration of the General Comfort Questionnaire and the selected technology was achieved. Key features such as authentication screens, a patient grid, instrument completion forms, and reporting tools were developed. The software's logo and overall layout were also designed. Subsequent phases involved validating the software’s appearance, usability, and functionality. The complete implementation will include making server layer elements available online and providing a beta version of the visualization layer on a public platform. The software aids nurses in efficiently and systematically assessing the comfort levels of postpartum adolescents, thereby facilitating care aimed at promoting comfort.
