Estudo de caso de aplicação de ferramentas da qualidade para melhoria contínua em uma indústria de confecção

Abstract

This work presents a case study on the implementation of continuous improvement practices in a garment industry within a sector known as the knitting room, characterized by low automation and limited value addition to the product. Using quality tools, such as flowchart, chronoanalysis, Pareto Diagram, Ishikawa Diagram and GUT Matrix, the study aimed to improve operational processes and optimize production efficiency. Starting with flow analysis by means of a flowchart, critical points in the production process were identified. The chronoanalysis provided a detailed understanding of the execution times and failures in the process, allowing the identification of opportunities to reduce steps in the process. The use of the Pareto Chart allowed for the effective prioritization of problems, focusing on the most impactful causes. The Ishikawa Diagram, in turn, helped in identifying the deep roots of problems, guiding solution strategies. The application of the GUT Matrix contributed to the classification and prioritization of corrective actions, considering the severity, urgency and trend of the identified problems. The results obtained revealed significant improvements in operational efficiency, reduction of set-up times and minimization of errors. The study demonstrates the effectiveness of quality tools as powerful instruments in the successful implementation of continuous improvement practices in industrial environments. This work not only highlights the tangible benefits achieved by the application of these tools, but also underscores the importance of a systematic and collaborative approach to continuously improve processes in challenging industrial environments.
