What is the defects per million opportunities (DPMO) of a process if the number of defects found in several lots are given along with opportunities for defect?

0.10250
102,500
68,750
0.06876

The correct answer is: 102,500

To determine defects per million opportunities (DPMO), you can use the following formula: DPMO = (Number of Defects / (Number of Opportunities)) × 1,000,000 In this scenario, if you were provided with data showing the total number of defects and the total number of opportunities for those defects, you would input those numbers into the formula to calculate DPMO. The reason why the selected value of 102,500 is valid is that it indicates there were 102,500 defects for every one million opportunities. This figure suggests a relatively high defect rate, which could be indicative of issues within the process that may need addressing. Values like 0.10250 and 0.06876 would indicate a much lower defect rate and wouldn't align with the context of the calculated DPMO if the defects and opportunities were significant. Similarly, 68,750, while a number that might appear relevant, doesn't account correctly for the scale expressed in millions based on the provided data. The DPMO is essential in Six Sigma as it provides a clear measure of quality performance, helping organizations understand and improve their processes.
