Explanation

DPU (Defects Per Unit) measures the average number of defects per product or unit. The formula is: DPU = Total Defects ÷ Total Units (or products). This differs from DPO (Defects Per Opportunity) which divides by opportunities, and DPMO which scales to million opportunities. DPU is a straightforward metric that tells you how many defects exist per product on average.
