The present study was carried out in a metal packaging manufacturing company located in Ensenada Baja California. The DMAMC methodology was applied in the "Define and Measure" stages for the analysis and to be able to propose strategies that allow to increase the efficiency, maintain the controls in the client - supplier chain, meet the client 's requirements and cover the requirements of use, opportunity, agreed cost and duration. The production line of the most sold product was selected and the critical characteristics of the global process were determined with key suppliers, inputs, outputs and users. The product that was selected represents 60% of the company's sales and has a high rejection percentage, which is equivalent to monthly losses of $ 12,500,000.00 dollars. With this study, we identified, in a timely manner, the factors that affect the performance of the processes and proposed solutions that can be implemented to increase productivity, quality and improve customer satisfaction.
