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 central concept of measure theory is that of a measure on a set \Omega Ω, which is a way to quantify the “size” of its subsets. However, it is usually impossible to assign such a “size” to every subset of \Omega Ω in a way consistent with the axioms of a measure.
