WebThe larger the Z shift, the more scope there is to improve the process by eliminating shifts and drifts in the process mean. Some industries define the sigma capability of a process as the long-term Z benchmark + a 1.5 Z shift. Meaning a process with a long-term Z benchmark of 4.5 is quoted as a Six Sigma process. 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 …
