DPMO stands for "Defects Per Million Opportunities" and is a way to measure how well a business process is working. It's like a report card that shows how many mistakes happen out of a million chances. This measurement is commonly used in quality improvement methods like Six Sigma and Lean Manufacturing. When you see DPMO mentioned in a resume, it usually means the person has experience in measuring and improving the quality of business processes. The lower the DPMO number, the better the process is performing. For example, if a company makes phones and has a DPMO of 100, it means there are 100 defects for every million opportunities for something to go wrong.
