使用方差分析 (Analysis of Variance , ANOVA) 的方法首先检验 LEAN 所实现的节约是否等于 SIX SIGMA 所实现的改善 { 附注:学习过 SIX SIGMA 的人都知道,假设检验是非常严格而且经得起考验的检验,不能凭口说某样东西有效果,或是某样东西没有效果。如果能用数据并使用假设检验,进行统计学的测试,那么这个结果的可...

Shewhart首先使用six sigma来衡量产品质量。 6 sigma : 每百万样本只有3.4个错误 (正确率99.99966%) 5 sigma: 每百万样本有233个错误 (正确率 99.7%). 上下两者相差68倍。 Sigma等级计算,即“正确率”。到达99.99966%就是6 Sigma。 如果做一件事的正确率是99.5%,也只能达到可怜的Sigma 4 - 4.1水平 ...
