The calculation of a Sigma level, is based on the number of defects per million opportunities (DPMO).
In order to calculate the DPMO, three distinct pieces of information are required:
a) The number of units produced
b) The number of defect opportunities per unit
c) The number of defects
The actual formula is:
DPMO = (Number of Defects X 1,000,000)/ ((Number of Defect Opportunities/Unit) x Number of Units)
