六西格玛是一种能够严格、集中和高效地改善企业流程管理质量的实施原则和技术。它包含了众多管理前沿的先锋成果，以”零缺陷”的完美商业追求，带动质量成本的大幅度降低，最终实现财务成效的显著提升与企业竞争力的重大突破。
    西格玛即希腊字σ的译音，是统计学家用语衡量工艺流程中的变化性而使用的代码。企业也可以用西格玛的级别来衡量在商业流程管理方面的表现。传统的公司一般品质要求已提升至3sigma.这就是说产品的合格率已达至99.73％的水平，只有0.27％为次货。又或者解释为每一千货产品只有2.7件为次品。很多人认为产品达至此水平已非常满意。可是，根据专家研究结果证明，如果产品达到99.73％合格率的话，以下事件便会继续在现实中发生：每年有20，000次配错药事件；每年不超过15，000婴儿出生时会被抛落地上；每年平均有9小时没有水、电、暖气供应；每星期有500宗做错手术事件；每小时有2000封信邮寄错误。由此可以看出，随着人们对产品质量要求的不断提高和现代生产管理流程的日益复杂化，企业越来越需要象六西格玛这样的高端流程质量管理标准，以保持在激烈的市场竞争中的优势地位。事实上，日本已把”6 Sigma”作为他们品质要求的指标。管理专家Ronald Snee先生将6西格玛管理定义为：“寻求同时增加顾客满意和企业经济增长的经营战略途径。”
    6西格玛管理专家Tom Pyzdek：“6西格玛管理是一种全新的管理企业的方式。6西格玛主要不是技术项目，而是管理项目。”
    下面是韦尔奇先生在接受美国著名作家珍妮特·洛尔采访时谈到的6西格玛管理：
“品质的含意从字面上来看，乃是要提供一个超越顶级的事物，而不仅是比大多数的事物更好而已。”80年代初，当通用电器面临竞争者的威胁时，韦尔奇曾说道：摩托罗拉、惠普科技、德州仪器和施乐公司并没有足够的资本与我们抗衡，而他们的竞争力来自于他们的产品品质。90年代中后期韦尔奇成为6西格玛品质热衷的追求者。1996年，在佛吉尼亚夏洛特城举行的通用电器公司的年会上，韦尔奇说：“在通用电器的进展过程中，我们有一项重大科技含量的品管任务，这项品管任务会在4年内将我们的生产方式引至一个卓越的层次，使我们无论是在产品制造还是在服务方面的缺陷或疵暇都低于百万分之四。这是我们通用电器前所未有的大挑战，同时也是最具潜力和最有益处的一次出击。”“我们推翻了老旧的品管组织，因为他们已经过时了。现代的品管属于领导者，属于经理人员，也属于员工—每一位公司成员的工作。”“我们要改变我们的竞争能力，所依恃的是将自己的品质提升至一个全新的境界。我们要使自己的品质使消费者觉得极为特殊而有价值，并且对他们来说是相当重要的成功因素。如此一来，我们自然就会成为他们最有价值的惟一选择。”
     我们可以把6西格玛管理定义为：“获得和保持企业在经营上的成功并将其经营业绩最大化的综合管理体系和发展战略。是使企业获得快速增长的经营方式。”6西格玛管理是“寻求同时增加顾客满意和企业经济增长的经营战略途径。”是使企业获得快速增长和竞争力的经营方式。它不是单纯的技术方法的引用，而是全新的管理模式。6西格玛管理具有以下特点：
    1) 比以往更广泛的业绩改进视角，强调从顾客的关键要求以及企业经营战略焦点出发，寻求业绩突破的机会，为顾客和企业创造更大的价值；
    2) 强调对业绩和过程的度量，通过度量，提出挑战性的目标和水平对比的平台；
    3) 提供了业绩改进方法。针对不同的目的与应用领域，这种专业化的改进过程包括：6西格玛产品/服务过程改进DMAIC流程，6西格玛设计DFSS流程等；
    4) 在实施上由“勇士Champion”、“大黑带MBB”、“黑带BB”“绿带GB”等经过培训职责明确的人员作为组织保障；
    5) 通过确定和实施6西格玛项目，完成过程改进项目。每一个项目的完成时间在3-6个月；
    6) 明确规定成功的标准及度量方法，以及对项目完成人员的奖励；
    7) 组织文化的变革是其重要的组成部分。
    六个西格玛的管理方法重点是将所有的工作作为一种流程，采用量化的方法分析流程中影响质量的因素，找出最关键的因素加以改进从而达到更高的客户满意度。如果你正在寻找一种使企业降低质量缺陷和服务偏差并保持持久性的新方法，那么不用犹豫了。六西格玛将以重大的财务成效证明你的选择是正确的。美国通用电气公司首席执行官韦尔奇先生在2000年年报中指出：
    六西格玛所创造的高品质，已经奇迹般地降低了通用电气公司在过去复杂管理流程中的浪费，简化了管理流程和降低了材料成本。六西格玛的实施已经成为介绍和承诺高品质创新产品的必要战略和标志之一。

实施六西格玛对于一个企业来说，不仅仅只是一系列的训练。它意味着整个企业文化从防护性的标准化管理到放开思想改革创新的突破性理念。六西格玛在提供行之有效的管理方法和流程技术的基础上，为企业培养了具备组织能力、激励能力、项目管理技术和数理统计诊断能力的领导者，这些人才是企业适应变革和竞争的核心力量。他们将最先进的工作方法和最新的电脑技术，应用到一个简单的流程模式DMAIC中，通过追求零缺陷运行和改善流程达到使顾客满意的快速突破性改善。以达到每一个环节的不断改善（Continuous Improvement）的战略目标。

Six Sigma

Six Sigma is a strict, concentration and effectively improve the quality of process management enterprise implementation principle and technology. It contains a number of management, in pioneer "zero defect" pursuit of perfect commercial, quality cost greatly reduced, and finally achieves the financial results of the improved and competitiveness of the breakthrough.
Sigma namely the Greek word σ, statisticians, measured in terms of changing process of the code. An enterprise may also use sigma level to measure in the business process management. The traditional company general quality request has been promoted to 3sigma. This means that the rate of products has reached to 99.73% level, only 0.27 percentage points for orders. And for every 1,000 goods or explanation for the defective product only 2.7 pieces. Many people think of this level has very satisfied. However, according to the research results show that if the expert 99.73% qualified products, following the incident will continue to occur in reality: a 20,000 times with the wrong medicine, Each year more than 15,000 not thrown born babies were born, An annual average 9 hours without water, electricity, heat supply, Each week had 500 cases do wrong operation, Every hour 2,000 letter mailed error. We can see that, as people to improve the product quality and the modern production management process, the enterprise and the complexity of the six sigma so as to high-end procedures, in order to maintain the quality management standard in the fierce market competition advantage. In fact, Japan has six Sigma "" as their quality requirement. Management experts Ronald Sneer six sigma management will define as: "seek increase customer satisfaction and enterprise management strategy of economic growth."
The six sigma management experts Tom Pyzdek: "the six sigma management is a kind of brand-new management enterprise. Six sigma project, it is main technical management project."
Mr. Welch below is the famous writer; Janet’s interview about six sigma management of:
"Quality the implications of the literal meaning, but from top to provide a transcendence of things, but not better than most of the things are." In the early 1980s, when faced with get competitor threats, Welch once said: MOTOROLA, HP technology, Texas instruments and Xerox and not enough capital and we compete, and their competitiveness from their product quality. The middle of 90's Welch becomes the six sigma quality keen admirers. In 1996, in Virginia charlotte city at the annual meeting of the general electric company, he said: "in the process of the progress of general electric, we have an important scientific and technological content of the product, the quality control tube task in 4 years task of our production to a superior level, make us whether in products manufacturing or services are free of defects or defects of four million below. This is our general electric unprecedented challenges, is also the most potential benefits and most of the time attack." "We overthrow the old qc group, because they are out of date. The modern leader, belong to belong to managers, also belong to the staff members of the company -- each job." "We want to change our competitive ability, the scholar-bureaucrats is their quality to a new realm. We must make oneself quality make consumers feel very special and valuable for them, and it is very important to success factors. Thus, we will become their most valuable only choice."
We can put the six sigma management is defined as: "get and maintain the success in business and operating performance of the maximization of comprehensive management system and development strategy of enterprise is to get. Rapid growth mode of operation. The six sigma management is "seeking and increase customer satisfaction and enterprise management strategy of economic growth." Enterprise is to obtain rapid growth and competitiveness of the mode of operation. It is not merely technical method, but new management mode. Six sigma management has the following features:
1) More than ever, the extensive performance improvement, emphasize the key requirements from customers and business enterprise strategic focus, seeking breakthroughs opportunity for performance of customers and create more value.
2) Emphasize on performance and process metrics, through measurement, challenging goals and level compared to the platform,
3) Provides the performance improvement methods. According to different purposes and fields of application, the specialization of improvement process includes: the six sigma product/service process improvement process, the six sigma DMAIC DFSS design process,
4) In the implementation of "the Champion", "big men", "black belt MBB black belt in BB" "green belt GB" trained personnel of responsibilities as the organizational safeguard,
5) Through six sigma project implementation and completion process improvement project, each project completion time in 3-6 months.
6) Specified standard of success and measuring method, and the rewards for completed project staff,
7) Organization culture change is the important component parts.
Six sigma management method "is all the work as a process, USES the method of quantitative analysis of the factors affecting the quality of process and find out the key factor of improved so as to achieve better customer satisfaction. If you are looking for an enterprise to reduce the quality defect and service and maintain the persistent deviations, so don't hesitate to new methods. Six sigma to financial results prove your choice is correct. American general electric company CEO Mr. Welch in 2000, an annual report that:
Six sigma is of high quality, create miracle has reduced the general electric company in the past the waste management processes of complex and simplify the management process and reduce the material cost. Six sigma implementation has become the introduction and commitment to innovation products of high quality and the symbol of a strategy.
