Defects per Million Opportunities (DPMO)

Six Sigma metric: (defects / (units x opportunities per unit)) x 1,000,000.

Definition

DPMO normalizes defect rates across processes with different complexity and maps to a sigma level; 3.4 DPMO corresponds to six sigma with a 1.5 sigma shift.

Example

25 defects in 500 units with 10 opportunities each: DPMO = 5,000.

Exam tip

Know the formula and that 6 sigma = 3.4 DPMO.
