Problem 1: Given the following defects information for 70 production units. Determine DPU: Defect 0 1 2 3 Units 31 22 12 4 0 Problem 2: Assume that each unit in Problem 1 has four opportunities for a defect (these are A, B, C, and D). Determine DPO and DPMO Problem 3: Assume that a process has a first pass yield of 0.90, determine the DPU. Problem 4: A process consists of 5 sequential steps: 1,2,3, 4, and. The yield of each step is as follows: Y1=96%, Y2=94%, Y3=92%, and Y4=95%. Determine the rolled throughput yield and the Total defects per unit
