Question

Cablesplice Inc.'s manufacturing process consists of 5 steps:making conductors, adding insulation, adding sheathing, irradiation and printing and coil cutting. Units are measured in meters. In 970,000 meters of cable, 700 defects were found in the conductors, and 75,000 defects were found in the insulation. In 44,000 meters of cable, 8,930 defects were found in the sheathing, and no defects were found in the in the remaining two steps.

1. Calculate DPU for each process step
2. Calculate the TY(throughput yield) for each process step using Method 1(DMAIC).
3. Estimate the sigma level for each process step.
