Defects calculation
How can one determine the amount of defect in one million chances?
The amount of defects in a million opportunity can also be called 'Defects Per Million Opportunities, DPMO'.

DPMO = 1000000 X DPO,
Where, DPO = D/(O X U).

D = Total Number of Defects,
O = Opportunities of Defects Per Unit
U = Total Number of Units.
