What are the general trends for defining dpmo. They way I understand it is dpmo = Total defects / Total opportunities. My question is that if there are two or more defects of the same kind on the board - such as - shots on a QFP. Now would this be counted as 1 defect or it would be counted as two or more defects. Because if it is counted as two or more the dpmo changes. I want to know what is the general industry practices. Any help will be appreciated.
