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 正确率(Yield)和sigma等级的定义 [概念] DPMO : ...

A Six Sigma control chart is proposed as a cross functional management tool and illustrated with an example. The benefits of using this control chart and the role of SAS programming are described. The fundamentals of Defects Per Million Opportunities (DPMO) and Defects Per Million Units (DPMU) ...
I have often been asked, why do we have 3.4Defects Per Million Opportunities (DPMO)for a Six Sigma process? Before I talk about Six Sigma, let's talk about the process control with plus-minus three sigmas. Historically processes were controlled in±3σ, and this was the basis ofcontrol ...
DPMOis a crucial tool within Six Sigma, as it defines the proportion of defects in 1 million opportunities. It essentially illustrates how often a fault or error occurs relative to every possible opportunity for a fault to arise. The formula to calculate the DPMO is the following: ...
