Estudo de eficiência produtiva em uma confecção industrial de bonés: diagnóstico e propostas de melhoria

Abstract

This study aims to propose improvement actions to increase productive efficiency in an industrial hat manufacturing plant located in the state of Paraná, focusing on the assembly sector. The research is justified by the need to optimize production processes in the face of operational bottlenecks, overload in specific cells, logistical failures, and impacts related to team instability. This is an applied case study with a qualitative approach and exploratory purpose. Data collection was carried out through direct observations, document analysis, qualitative and quantitative data sheets, and informal interviews with employees. Production records, daily targets, efficiency indices, and various operational factors were analyzed. The analysis was conducted with the support of quality tools such as the Ishikawa Diagram, Pareto Chart, and the 5 Whys Method, making it possible to identify, structure, prioritize, and analyze the root causes of the main variations observed. Two production groups, A and B, were analyzed. The results indicated significant performance variations between the groups, with group A showing greater efficiency compared to group B, whose average was consistently below the established target. The segmented analysis by production cells revealed critical points and opportunities for improvement, providing assistance for the development of corrective and strategic actions in the production environment.
