【摘要】：二十世纪八十年代,面对日本企业的质量竞争,美国摩托罗拉公司为了扭转低劣产品质量的局面,正式推广“六西格玛质量计划”,产生了非常好的结果。这源于摩托罗拉公司,由通用电气公司成功推广的六西格玛管理,被世界上越来越多的企业所接受。如今,六西格玛管理成为公认的璀璨明星,风靡管理界。 六西格玛管理方法以数据和事实为依据,以满足客户需求为宗旨,以提高效率和减少成本为目标,以对生产和服务流程的持续改进为根本,以全员参与,建立和改善企业文化为灵魂的科学而严谨的管理方法。六西格玛管理方法基于建立可测量的方式,借助统计工具评估的一整套解决问题的方案。 本文介绍了质量管理的历史,六西格玛诞生的背景,介绍了六西格玛的内容和特点,逐渐深入地介绍了西格玛改进DMAIC,结合CCMC公司的机加工标准工时降低项目的实例,探讨了六西格玛管理的具体应用步骤,及在此项目中的认识。首先,项目定义阶段明确了项目章程,尤其是项目目标Y和影响因子X；其次,测量和分析阶段识别出项目需要重点改进的方向：机加工程序的改进,随后的改善与控制阶段,对项目进行了具体实施,运用流程能力Cpk验证了改进的质量可靠性,运用方差分析(ANOVA)验证了改进的有效性。最后,分析了项目的财务收益,即2013年度预计收益为713,458元,达到预期目标703,671,圆满完成项目。用具体案例说明六西格玛管理支持企业不断流程改进的成功。
[Abstract]:In the 1980s, in the face of quality competition from Japanese enterprises, Motorola formally promoted the "six Sigma quality Plan" in order to reverse the situation of poor product quality, which produced very good results. This stems from Motorola, managed by six Sigma, successfully promoted by General Electric, and is accepted by more and more companies around the world. Today, six Sigma management has become recognized as a bright star, popular in the management world. The six Sigma management method is based on data and facts, aims at meeting customer needs, aims at improving efficiency and reducing cost, takes the continuous improvement of production and service process as the foundation, takes the whole staff participation, establishes and improves the enterprise culture as the soul of the scientific and rigorous management method. The six Sigma management method is based on the establishment of a measurable approach, with the help of statistical tools to evaluate a set of problem-solving solutions. This paper introduces the history of quality management, the background of the birth of six Sigma, introduces the contents and characteristics of six Sigma, gradually introduces the example of Sigma improvement DMAIC, combined with CCMC company's machining standard working hours reduction project, probes into the concrete application steps of six Sigma management and the understanding in this project. First of all, the project definition stage defines the project charter, especially the project objective Y and impact factor X. secondly, the measurement and analysis stage identifies the key improvement directions of the project: the improvement of machining program, and then the improvement and control stage, the project is implemented concretely, the quality reliability of the improvement is verified by process capability Cpk, and the effectiveness of the improvement is verified by variance analysis (ANOVA). Finally, the financial income of the project is analyzed, that is, the expected income in 2013 is 713458 yuan, which achieves the expected target 703671 and completes the project successfully. A concrete case is given to illustrate the success of six Sigma management in supporting continuous process improvement in enterprises.
