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
