Abstract

When improving a process quality using Six Sigma methodology, sigma metric as a measure of quality is introduced. The metric is computed using a special table which converts defects per million opportunities (dpmo) to sigma level. The article shows that when sigma quality of a process is under 3,2, the metric can distort the original information about the process quality contained in dpmo.
