Defects Per Million Opportunities (DPMO)

The average or ratio of the number of defects per unit observed during an average production or service run divided by the total number of opportunities to make a defect on a product or service normalized to the number 1,000,000.

Calculating DPMO

​-To Calculate DPMO from DPO simply multiply DPO by 1,000,000.
- To Calculate DPMO from DPU - DPU/(opportunities/unit) x 1,000,000.
