Long term process sigma level formula

WebProcess 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? ). The theoretical defect rate for a Six Sigma process is 3.4 defects per million ... WebSigma (σ) is the standard deviation of the process. If you enter an historical value for σ, then Minitab uses the historical value. Otherwise, Minitab uses one of the following methods to estimate σ from the data.
