This figure is a just a probability of failure.
This parameter, known as the defects per million opportunities, calculates the probability that a process’s defect probability per million units produced.ĭPMO for the bottle manufacturing process is calculated as: All give the same result, so once you know one…you know them all. There are more than one formula for calculating the DPO, but this is the simplest. Three parameters are integrated to facilitate this calculation: The defects per opportunity measures the probability of defects being generated by a system.
