Quizplus · Accepted Answer

The defect rate is calculated as the number of defects per million opportunities (DPMO). With 32 parts per unit, there are 32 opportunities for defects per unit. The total opportunities are 13,250 units * 32 = 424,000. With 7,650 complaints, the DPMO is (7,650 / 424,000) * 1,000,000 ≈ 18,066. This corresponds to a Six Sigma level slightly better than 3.5.
