DPO – Defects per opportunity

Calculation used in Six Sigma and DFSS, (Design for Six Sigma). The total number of possible errors or defects that could be counted in a process or service. The formula uses the number of defects and the number of units times the DO,(defect opportunities).

DPO  = Number of defects

Number of units x Number of opportunities

One way to calculate PPM you would use one, (1), as the number of opportunities and then use the DPMO, (Defects per Million Opportunities), formula to calculate PPM. (see the note on the DPMO page)

We have a free and commercial product to aid you in these calculations. See our free DPO-DPMO calculator and the commercial DPO-DPMO calculator for more details.
