The following slides show how to calculate DPMO, which stands for Defects Per Million Opportunities.

A word of caution:  keep things simple whenever possible, and avoid using metrics like DPMO, DPO, and DPU unless they offer a clear advantage. In the case below, we recommend using a metric that all levels of the organization will understand, like average defects per order (total defects divided by total orders).

Remember, Six Sigma is about understanding and improving our processes to achieve tangible results.
