The present research project presents as a limiting factor in SMEs, the low production efficiency of falsework with a value of 68.48%, this value is below the world standard of the industrial sector 75%. This deficit caused by the inadequate programming of maintenance and execution of machines, absence of procedure in the change of line, deficient order and classification of raw material and reduction in the cutting and welding process, lack of standardization of the welding process and responsibility not assigned in welding quality control. The impact of the problem is reflected in costs associated with overtime, a reprocessing cost and penalties for late delivery of orders. The main contribution of the research is the design of the model by adapting the tools of the Lean Manufacturing philosophy focused on an SME such as TPM, SMED, 5S, process standardization and Jidoka. The proposed design has two levels, strategic and tactical. At the strategic level, by managing KPIs and identifying waste through the value stream map (VSM) and being able to eliminate them using Lean Manufacturing tools. The model is based on the application of tools relating the tactical level with all the actors of the processes through the design of the manufacturing processes, the design of working methods and the design of the product. Finally, the processes are evaluated for the evolution of the indicators of each of the processes. The implementation of the techniques improved production efficiency to 75%. The indicators were validated through the simulation of the model, in the rolling process the OEE increased from 65.03% to 78.23% and the internal preparation time decreased by 61.53%. In the cutting process, the audit score was improved from 1.58 to 4.25, on a 5-point scale. In the welding process, the OEE increased from 62.20% to 76.14%, the average welding time decreased by 25%, the number of reprocessed forms decreased by 58.33% and the number of approved forms rose from 87% to 90%. Finally, the results of the application of the proposal highlighted the viability of the project from the technical and economic aspect.
