these figures assume that the process mean will shift by 1.5 sigma toward the side with the critical specification limit. in other words, they assume that after the initial study determining the short-term sigma level, the long-term c value will turn out to be 0.5 less than the short-term c value. so, now for example, the dpmo figure given for 1 sigma assumes that the long-term process mean will be 0.5 sigma beyond the specification limit (c = –0.17), rather than 1 sigma within it, as it was in the short-term study (c = 0.33). note that the defect percentages indicate only defects exceeding the specification limit to which the process mean is nearest. defects beyond the far specification limit are not included in the percentages.
