Formula:

DPMO = (Total defect/Total Opportunities) x 1000000 Defect (%) = (Total defect/Total Opportunities) x 100% Yield (%) = 100 - Defect (%) Process sigma = 0.8406+sqrt(29.37)-2.221 x (log(DPMO)) Where, Opportunities = Lowest defect noticeable by customer DPMO = Defects Per Million Opportunities
