The combination of Six Sigma with Total Quality Management (TQM) has emerged as an effective technique for increasing operational efficiency and reducing faults, particularly in the beverage industry. This study looks at how Six Sigma methodologies, specifically DMAIC (Define, Measure, Analyze, Improve, Control), Cause and Effect (CE) analysis, the 5W2H framework, the PDCA (Plan, Do, Check, Act) cycle, and Control Charts, can be used within the TQM framework to reduce defects significantly. The study examines production data both before and after these approaches are put into practice using a quantitative approach. The results show a significant decrease in defects, proving that Six Sigma tools combined with TQM techniques efficiently optimize workflows and enhance product quality. Production processes were significantly improved by the application of PDCA and DMAIC cycles, and CE analysis and 5W2H highlighted important areas for development. Throughout the deployment, control charts played a crucial role in monitoring and preserving process stability. Despite those positive findings, the study recognizes many shortcomings such as the difficulties in incorporating Six Sigma into current organizational designs and the substantial resources needed for effective execution. The outcomes highlight how crucial an effective support system and the commitment of senior management are to attaining long-term gains. Future studies should examine how sustainable the defect reduction made possible by this integrated approach is over the long run and whether it can be applied to other areas of the food and beverage industry. Further research is necessary to fully understand the possibilities of utilizing advanced technologies like artificial intelligence and machine learning to improve defect minimization processes.
