The implementation of Lean Manufacturing (ME) techniques and tools in the production process flows has been assuring the organizations gains in efficiency and increase in productivity. When the concepts of lean manufacturing are successfully implemented, there is a reduction in errors of execution, waste, and the expenses necessary to resolve them. These characteristics are essential for any company that seeks to stand out in its market, given the current pandemic scenario, with strong competition among them. In this context, this study implemented the Value Stream Mapping tool (VFM) in a large electrical products manufacturing company, located in northern Parana. The implementation occurred in the concreting process, integral in the manufacture of Double T poles, and aimed to increase the production volume and reduce its lead time. The application of MFV and the concepts and techniques of ME resulted in the projection of the elimination of one of the stages of the process and the improvement of the analyzed indicators.
