Análise comparativa de metodologias de gestão de processos Lean e Six Sigma: revisão sistemática

Abstract

This study aims to identify and analyze the approaches of the Lean Six Sigma methodology adopted qby companies operating in the manufacturing sector, based on a literature review. These production methodologies are employed by companies to improve their productivity, competitiveness, and quality management. For this study, the SPELL, Google Scholar, and SciELO platforms were used as methodological bases, enabling a comprehensive and rigorous literature review. The theoretical review begins with a discussion of these concepts and then presents how the tools of Lean Manufacturing, Six Sigma, and the combined Lean Six Sigma methodology were created and characterized. The results highlighted five tools used in more than two analyzed articles: DMAIC, SIPOC, Ishikawa Diagram, Pareto Diagram, and 5W2H. Finally, the study provides a theoretical survey of how manufacturing companies implement these methodologies to maintain market competitiveness, reduce costs, increase productivity, and fully understand their customers and internal processes.
