TOC改善实施效果是6sigma的20倍, Lean的9倍

        作为全球两大热门管理方式6sigma与lean模式, 近年来国内众多大型企业先后导入这些管理模式, 取得的实际改善成果是多了一堆虚伪的6sigma? 或lean改善报告? 还是产生了实际的改善成果?

        或许，只有那些企业的CFO们知道了。在2006年, 美国生产运营管理权威机构—美国运营管理协会(APICS)抽查了21家企业的100多个改善项目, 其中有11家导入了6sigma, 4家企业导入了lean, 6家企业在导入前面两种管理模式后,又导入了TOC管理模式, 结论得出:
        TOC的改善效果是6sigma的20倍, 是lean的9倍, 并将研究结果在2006年5月的APICS杂志进行发表。

(A study released in the May, 2006 APICS magazine demonstrates that TOC is twenty times as effective as Six Sigma, and nearly ten times more effective than lean at causing cost savings. I find this remarkable result especially interesting because cost savings are a side benefit of TOC...TOC focuses on increasing Throughput.

This is the only scientific double-blind study of its kind performed "in the wild", i.e. in actual business plants. The authors summarize the results of over 100 improvement projects, where:

11 plants applied Six Sigma
4 plants applied Lean
6 plants applied TOC, Lean and Six Sigma 
 

The results are unequivocal:

A little further analysis shows:

If we assume linearity (i.e. that the treatments are additive), we can estimate TOC alone. The 11 six sigma plants saved 0.63% per plant, and the 4 Lean plants saved 1.5% per plant. So, we subtract 6x(.63+1.5) = 13% for the 6 plants that did the combined, the estimated TOC alone savings is 76%, or ~13 % per plant. So, TOC is twenty times more effective than six sigma, and around nine times more effective than lean.

 Lean Project Management (LPM), API's extension of CCPM, takes the same approach as the workers in these plants: combining the synergistic effects of the three improvement approaches. The combination caused savings of 14% (of the total saved) per plant, or 24 times more effective that six sigma alone, and ten times Lean alone.

牛！我刚买了本中文版来看

可以考虑结合TLS来做实践改善。

Velocity: Combining Lean, Six Sigma and the Theory of Constraints to Achieve Breakthrough Performance - A Business Novel

http://www.amazon.com/Velocity-C ... 30995524&sr=8-1

Book Description
Publication Date: December 29, 2009
Millions of readers remember The Goal, the landmark business novel that sets forth by way of story the essential principles of Eliyahu Goldratt's innovative methods of production. Now, from the AGI-Goldratt Institute and Jeff Cox, the same creative writer who co-authored The Goal, comes VELOCITY, the book that reveals how to achieve outstanding bottom-line results by integrating the world's three most powerful continuous improvement disciplines: Lean, Six Sigma, and Goldratt's Theory of Constraints.
Used by the United States Navy and United States Marine Corps to dramatically improve some of the most complex, logistically vast supply chains in the world, the VELOCITY APPROACH draws on the strengths of all three disciplines to deliver breakthrough performance gains. In physics, speed with direction is velocity; in business, the application of VELOCITY means your organization can achieve operational speed with strategic direction to outmaneuver competitors, gain loyalty with customers, and rapidly build sustainable earnings growth -- in as little as one or two business quarters.

每个企业用了不同的工具，关键在于关于这对这些工具的认识，效果如何，工具决定不了一切，工具只是一个因素而已，关键在于全员的思想观念（企业文化）。

回复 sxczwjh 的帖子

执行的过程中太多的不确定性因素，而每个企业面对的又是完全不同的。
例如：TOC中的VV项目，若企业没有良好的管理基本和人力智力支持，基本是玩不转的。

不一定认可该观点，主要看你执行的如何

需要注意的是：仅仅降低OE或I（取决于一个明确的点，即服务的客户），是不可能的，结果是失去销售。另一方面，潜在的提高销售收入是无限的，只要在比其它竞争对手更快、更好地提供产品或服务的时候就能创造客户价值。
因此，最有效的方式是：通过提升销售收入来达到最大化收益率和投资回报率（ROI）。

回16楼：
TOC能给企业带来什么？
用老高的话说，就是提升销售收入，降低运营费用和投资（库存）。

回17楼：
国内确实有不少的成功案例，据我与这些咨询师交流所知道，有几个HK咨询公司就有这样的案例分享。
