Motorola derived the sigma level from attribute tracking of quality. What does "five sigma" mean? It means that the results would occur by chance alone as rarely as a value sampled from a Gaussian distribution would be five standard deviations from the mean. The Excel function 1- normsdist(5) computes that the fraction of the normal distribution that is greater than five standard deviaitons from the mean. Process sigma (also referred to as sigma level) is a measure of process capability: the higher the process sigma, the more capable the process is. A Six Sigma process has a short-term process sigma of 6, and a long-term process sigma of 4.5 (see why not 4.5 sigma?).

So why does Six Sigma require six standard deviations between the mean and the nearest specification limit? 2012-02-09 5-sigma: 99.99994 percent So that means that purely statistical fluctuations will give you a result way out in the 5-sigma range 0.00006 percent of the time. When physicists announce that they have a 5-sigma result, that means that there's a 1 in 3.5 million chance that it was the result of a statistical fluctuation over the spectrum of 5-sigma: 99.99994 percent So that means that purely statistical fluctuations will give you a result way out in the 5-sigma range 0.00006 percent of the time. When physicists announce that they have a 5-sigma result, that means that there's a 1 in 3.5 million chance that it was the result of a statistical fluctuation over the spectrum of Sigma level is tossed around these days with no true understanding. The lower quality six sigma programs have sort of equated the sigma level with the number of standard deviations away from the mean (a z-score). I am an old six sigma guy and was there when it started.

The video explains the concept of Sigma Level using a simple example. You will also find detailed explanation of the concepts like normal distribution, stand (Note that 3.4 per million actually corresponds to a 4.5 sigma process since an additional 1.5-sigma is included to account for experimental bias.) The choice of which significance level to use is always a subjective one and conflicts with the scientist or engineer’s intention to conduct an objective test. The Sigma Level provides a high level baseline metric to understand the capability of a process (or entire organization) to meet customer requirements. As indicated in figure below [1], the normal probability distribution predicts a 3.4 defects per million opportunities (DPMO) for a Sigma Level of 4.5 and 0.002 DPMO for Sigma Level of 6. Motorola has determined, through various studies on process data collected for years, that the process average (mean) is likely to shift over the long term by +/- 1.5.
