Explanation

Six Sigma is a quality management methodology that aims for near-perfection by limiting defects to no more than 3.4 defects per million opportunities (DPMO). This corresponds to a 99.99966% perfection rate. The sigma level refers to standard deviations from the mean in a normal distribution - Six Sigma means six standard deviations between the mean and the nearest specification limit.
