DPO (Defects Per Opportunity)
Defects Per Opportunity
Number of defects divided by the total number of possible defect opportunities.
Examples
- 01An order-entry audit finds 30 errors in 100 forms with 20 fields each, so DPO is 30 divided by 2,000, or 0.015.
- 02During Measure, the team uses DPO to compare a short 8-field form with a long 40-field form on a fair basis.
- 03The tollgate review documents DPO before and after the new form design: from 0.015 down to 0.004.
