d. Stakeholders
Explanation / Answer
Answer:
1. The initial step in any six sigma methodology is Define. However, since in this step be actually define the problem therefore Problem definition can also be correct answer in some peoples view. According to us the correct answer is Option b. Define.
2. Throughput Yield = e-DPU ; here, DPU is Defects Per Unit
Average Yield in the given question = 99.80 + 97.40 + 96.40 / 3 = 97.8667 therefore, 97.8667 = 2.71828-DPU or DPU =
3. Defects expected in 1 million opportunities = 80 x 1,000,000 / 1000 = 80,000; Correct answer is Option d.
4. The approximate Six Sigma Level of the process which has DPMO 860 is 4.60 approx. if 1.5 sigma shift over normal distribution is assumed.
5. These other parties are known as Stakeholders. Option d. is correct answer.
