This is the reason why a 6σ (Six Sigma) process performs better than 1σ, 2σ, 3σ, 4σ, 5σ processes. The more number of standard deviations between process average and acceptable process limits fits, the less likely that the process performs beyond the acceptable process limits, and it causes a defect.

Standard Deviation (also known as Sigma or σ) determines the spread around this mean/central tendency. What is Sigma and Why is it Six Sigma? Mean is the arithmetic average of a process data set.Ĭentral tendency is the tendency of data to be around this mean.
