【摘要】：随着经济全球化和中国经济的迅猛发展，中国电梯行业迎来了前所未有的巨大机遇，但大批企业的进入，使市场竞争日益激烈，企业利润空间严重缩小。对企业来讲，只有以客户为导向，不断提高产品服务质量，才可能在竞争中不断生存发展。本文以S电梯公司天津制造基地为企业研究案例，从实际收到的市场反馈数据出发，分析公司目前的产品质量现状，导致质量问题的深层次原因，探讨产品质量改进的具体实施过程。论文首先从基本理论入手，提出将六西格玛理论、精益思想和S公司内部推行的运营体系—ACE相结合的技术路径，并选取最主要的客户问题反馈--包装作业错漏件为典型案例，详细介绍作业流程，，运用SIPOC图、鱼骨图、FMEA、价值流分析等手法深入查找问题的根本原因，之后提出单件流的流程改善方案并加以有计划地实施。实践证明，此改善取得了较好的成果。企业已准备在供应商处试点推行。之后本文针对不同的职能部门，包括管理层、设计部门、质量管理、供应链管理等，提出相应的可行性改善建议，不仅使企业外部客户满意度提高，也要关注内部客户的满意度水平，力争将好的改善方法和不断追求完美的思想融入员工的思想理念和日常工作中，提升整个供应链的竞争力。本文希望通过对典型案例的研究，挖掘企业内部行之有效的措施，以提高产品质量和工作质量，并将好的经验进一步推广到供应商处。通过系统的理论知识与实际的企业案例分析提出合理的调整与改进建议，以帮助企业保持可持续化的竞争优势。

For enterprises, only customer-oriented, continuous improvement of product and service quality, can continue to survive and develop in the competition. This article takes S elevator company Tianjin manufacturing base as the enterprise research case, from the actual received market feedback data, analyzes the company's current product quality status, leading to the deep-seated cause of the quality problem. Discuss the concrete implementation process of product quality improvement. This paper starts with the basic theory and puts forward the technical path of combining six Sigma Theory, Lean thought and the operating system ACE implemented by S Company, and selects the most important customer problem feedback-packing work missing parts as a typical case. This paper introduces the operation flow in detail, uses SIPOC diagram, fish bone map and value flow analysis to find out the root cause of the problem in depth, and then puts forward the process improvement scheme of single piece flow and implements it in a planned way. Practice has proved that this improvement has achieved better results. Enterprises are ready to pilot implementation at suppliers. Then this paper puts forward the corresponding feasibility improvement suggestions for different functional departments, including management, design, quality management, supply chain management, etc., which not only makes the external customer satisfaction increase. We should also pay attention to the level of internal customer satisfaction and strive to integrate good methods of improvement and continuous pursuit of perfect ideas into employees' ideas and daily work to enhance the competitiveness of the entire supply chain.
