Otimização do processo de desenvolvimento de software: aplicação de análise de causa raiz para redução de falhas em produção

Abstract

This study investigates the causes of production failures in software development within a financial squad, aiming to reduce the occurrence of these failures and discuss process improvements. Root Cause Analysis (RCA) techniques were applied, including the Five Whys Method and the Fishbone Diagram, using data extracted from Azure DevOps and structured interviews with the team. The results identified recurring issues such as lack of technical training, incomplete specifications, communication failures, inconsistencies in development environments, deadline pressures, and outdated documentation. Based on these analyses, the study suggests actions such as team training, documentation standardization, test automation, and the adoption of collaborative tools. Although the proposals require validation in the financial squad’s context, the findings highlight the importance of structured processes to ensure stable and reliable systems.
