Uso de ferramentas Lean Six Sigma para melhoria de eficiencia e redução de tempos improdutivos em micro e pequenas empresas

Abstract

This study investigates the application of Lean Six Sigma tools to improve efficiency and reduce unproductive times in micro and small companies in the interior of São Paulo. These businesses face inefficiency and wasted time issues that negatively impact their productivity. Detailed analysis of the data collected, including equipment arrangement and workflow, revealed significant inefficiencies. To solve these problems, tools such as the Spaghetti Diagram and Value Stream Mapping were applied. Based on these analyses, the Lean Six Sigma methodology, including 5S and layout improvements, was chosen for its effectiveness in optimizing processes and making better use of available space. Expected outcomes include increased productivity, reduced cycle time, and better use of space. The application of these improvements has already demonstrated a notable increase in the operational efficiency of the companies studied.
