Question

Quizplus · Accepted Answer

The DPU measurement of this process is 0.0125.
Key Takeaway: Defects per Unit or DPU is a process performance metric that calculates the defect occurrence rate depending on a production cycle or process. In this example, the total number of defects per 10,000 pencils produced = 80 + 45 = 125 defects.
The DPU = Total Number of Defects ÷ Total Number of Units
= 125 ÷ 10, 000
= 0.0125
