Application of the Six Sigma Methodology and Use of the DMAIC Method to Reduce the Loss Rate of Aluminium Cans in a Beverage Industry to Reduce Operational Costs: Case Study: Latax Refrigerantes Ltda

Abstract

Six Sigma is an internationally recognized tool widely used to identify and implement improvements in an organization’s internal processes, aiming at reducing operational costs and increasing profit margins. This study demonstrates how the application of Six Sigma can assist in reducing operational costs by minimizing can losses in the production process through cause analysis and the implementation of action plans in an aluminum can soft drink production line. The DMAIC methodology (Define, Measure, Analyze, Implement, and Control) was used, along with statistical tools such as VOC (Voice of the Customer), Ishikawa Diagram, and SIPOC. The results indicate that, after implementing the proposed actions, the average can loss rate was reduced from 0.53% to 0.26%, resulting in an annual savings of approximately $6,926 for the company.
