    Problem :
    Units Produced = P = 100
    Defects Found = D = 3
    Parts per Unit = PPU = 17
    Number of Operations = Op = 8
    Solution:
    Defects per Unit = DPU = 3/100 = 0.03
    Defects per Opportunity = DPO = DPU/PPU  = 0.03/17 = 0.001764
    Defects per Million Opportunities = DPMO = 1764
    Throughput Yield = Ytp =  e (-0.03) = 0.97
    Normalized Yield per Operation = (Ytp) ^(1/Op)
                                                      = (0.97)^(1/8)
                                                      = 0.996
    OP PPU P   Therefore your equation  8+17+100 is wrong.
