USE OF LEAN METHODOLOGY AND TOOLS IN PRODUCTION MANAGEMENT TO IMPROVE THE EFFICIENCY OF THE PRODUCTION PROCESS - CASE STUDY IN A PIM COMPANY

Global competitiveness and production complexity in modern industries highlight the need for methods to improve efficiency and productivity. Industrial modernization faces challenges such as complex processes, demand variability, and resource limitations, requiring fast and assertive solutions to avoid inefficiencies and loss of competitiveness. In Brazil, the Manaus Industrial Hub (PIM) exemplifies how methodologies and tools such as Lean Manufacturing, Yamazumi chart, Ishikawa, Line Balancing, 5 Whys, 5W2H, and Basic Matrix help to overcome logistics costs and regulatory pressures, optimizing resources and demands. Together with Production Planning, these methodologies and tools minimize costs, maximize productivity, eliminate waste and bottlenecks, and increase competitiveness. Focusing on the manufacture of loudspeakers, this qualitative, exploratory research, through a case study with bibliographic and documentary research, identified practices to optimize processes and solve problems, generating improvements in the production rate with a 21.9% increase in production capacity and labor efficiency with a 10.7% reduction in the number of operators on the line, generating a positive impact on business results.
