英文摘要：	This research paper presents a comprehensive investigation into the application of Six Sigma management methodology for improving product quality in multinational enterprises operating in emerging markets, with particular emphasis on T Company's electronic component products in the Mexican market. The study emerges against the backdrop of accelerating globalization, where multinational corporations increasingly face complex operational challenges, especially in developing economies characterized by underdeveloped infrastructure, significant cultural differences, and inefficient supply chain systems. Statistical data reveals that by the end of 2024, more than 1,300 Chinese manufacturing enterprises, predominantly from the automotive and electrical industries, have established operations in Mexico. While these companies have demonstrated remarkable success in other international markets, their Mexican operations frequently encounter severe quality deterioration problems attributable to multiple factors including fragmented supply networks, transportation limitations, varying customer quality expectations, political and economic instability, as well as distinct natural environmental conditions. The consequent quality defects have resulted in substantial financial losses and constrained market development for numerous enterprises, thereby making the establishment of effective quality management systems an urgent priority requiring thorough investigation and practical solutions. The research methodology employed in this study systematically applies the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) framework to address the high customer complaint rates experienced by T Company in the Mexican market. The investigation focuses on a representative electronic component product, conducting detailed analysis of its manufacturing processes to identify critical quality defects including resistance value exceedances, welding spatter formation, riveting height deviations, and electroplating imperfections. Through rigorous application of Six Sigma tools and techniques, the study successfully identifies root causes for these quality issues and develops comprehensive optimization solutions encompassing multiple aspects such as welding and plating process improvements, supply chain coordination mechanisms, digital traceability system implementation, quality inspection and feedback procedure enhancements, environmental adaptability optimizations, as well as personnel training and quality culture development initiatives. The paper commences with a detailed exposition of the research background, significance, and objectives concerning the utilization of Six Sigma methodology for quality improvement in T Company's electrical components. This is followed by a comprehensive overview of the Six Sigma management system, including its theoretical foundations and practical implementation frameworks. Subsequently, the current operational status of the electronic component product is thoroughly examined, with particular attention to existing testing and quality control problems analyzed through the Six Sigma perspective. Based on this analysis, targeted improvement measures are developed and implemented using Six Sigma methodology. The study concludes with a rigorous evaluation of improvement outcomes, along with summary conclusions and future research directions. The research content is systematically organized into six substantive chapters, each addressing critical aspects of the quality improvement initiative: Chapter One: Introduction This chapter provides a comprehensive background analysis, including detailed examination of Mexico's rapidly developing electrical manufacturing industry, the strategic market position occupied by T Company, and the specific operational challenges encountered by the electronic component product line. The discussion emphasizes the severity of existing quality problems and the compelling necessity for this research, while clearly articulating both the theoretical contributions and practical applications of the study. Additionally, this section presents a detailed technical roadmap outlining the research methodology and implementation approach. Chapter Two: Theoretical Framework and Literature Review This section offers an in-depth introduction to Six Sigma theory, systematically explaining its fundamental concepts, core principles, and practical application methodologies. The DMAIC process framework receives particular attention, with detailed explanation and comprehensive summary of each phase. Furthermore, the chapter provides thorough technical specifications of the electronic component product under investigation, including precise descriptions of its key characteristics, measurement methodologies, and quality control requirements. The literature review component presents a comparative analysis of Six Sigma research and application status between domestic Chinese and international contexts, thereby establishing a solid theoretical foundation for the subsequent quality improvement project implementation. Chapter Three: Definition and Measurement Phases This chapter presents a meticulous examination of each production process stage for the electronic component product, accompanied by comprehensive quality status assessment. The analysis employs Pareto diagram methodology to identify and prioritize critical quality defects and their underlying causes. Comparative quality performance data between Mexican and European Union markets is systematically analyzed to establish clear internal improvement targets. The research team composition is carefully designed to incorporate cross-functional expertise. Measurement System Analysis (MSA) is conducted on primary measurement instruments to evaluate system performance characteristics, while Process Performance Index (Ppk) analysis quantifies current quality levels, thereby creating a robust data foundation for subsequent improvement initiatives. Chapter Four: Analysis and Improvement Phases This section extensively applies Six Sigma statistical tools, including Design of Experiments and regression analysis techniques, to conduct root cause analysis for key quality problems such as resistance exceedances, welding defects, riveting height deviations, and plating imperfections. The investigation successfully identifies critical factors influencing product quality, thereby providing scientific basis for improvement measures. Based on these findings, comprehensive optimization solutions are proposed and implemented across multiple quality parameters including resistance values, welding quality, riveting dimensions, and plating thickness specifications. Chapter Five: Effectiveness Evaluation and Control This chapter systematically assesses the implementation results of quality optimization solutions through rigorous verification processes. The evaluation confirms successful execution of root cause improvement activities and thoroughly examines the effectiveness of solutions proposed in Chapter Four. Post-improvement process capability and product quality performance metrics, both internally and in customer applications, are carefully validated to ensure sustainable results. Chapter Six: Conclusions and Future Research Directions The final chapter synthesizes key research findings, including detailed quality optimization achievements, production efficiency gains, cost control improvements, and the establishment of robust process monitoring systems. The discussion elaborates on both theoretical and practical contributions of the study, while objectively analyzing research limitations. Practical recommendations are provided for enterprise future development, along with clear identification of promising research directions. The conclusion emphasizes the broader significance of the research and expresses expectations for future advancements in the field. The research results conclusively demonstrate that quality optimization solutions incorporating Six Sigma methodology can effectively address quality challenges faced by multinational enterprises operating in unique environmental conditions. This study not only provides practical guidance for T Company's quality enhancement initiatives in the Mexican market, but also offers valuable theoretical reference and implementation framework for other multinational corporations confronting similar globalization challenges. Peer enterprises may benefit from the experiences documented in this research by continuously optimizing their quality management systems, deepening supply chain collaboration mechanisms, expanding market development strategies, and pursuing product innovation pathways, thereby achieving sustainable business development objectives.
