Question

Consider a company that provides two services using the same basic process. Service A is relatively complex, and has 15 opportunities for a defect. Service B is relatively simple, with only 5 possible defect opportunities. The company produces 500 units of A and 1000 units of B. A total of 10 defects are experienced in service A and 17 defects are experienced in service B. What is the DPMO (Defects Per Million Opportunities) for the overall process?

Answer 1

Answer:

The answer is: Total DPMO of the overall process is = 4,733.33

Explanation:

To calculate the defects per million opportunities (DPMO) we use the following formula:

       DPMO = (D/(U*O))*1,000,000

• Defects = D
• Unit = U
• Opportunity to have a defect = O

We are given the following data:

Service A:                                           Service B:

D = 10                                                  D = 17

U = 500                                              U = 1,000

O = 15                                                  O = 5

DPMO Service A = [10 / (500 x 15)] x 1,000,000 = 1,333.33

DPMO Service B = [17 / (1,000 x 5)] x 1,000,000 = 3,400

Total DPMO = 4,733.33
