Problems for Practice Quality Management Problem 1: Given the following defects information for 70 production units. Determine DPU: Defect 0 3 Units 31 22 12 5 1 2 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. Problem 5: a. The first pass yield for a single operation is 94%; what is the probability of a defect, and what is the Z value? b. The first pass yield for a single operation is 98%; what is the probability of a defect, and what is the Z value? What is the long and short term of the part (a) d. What is the Z Long and short term of the part (b) Problem 6: If a process were producing 70 defective/million, what would be the 6-sigma quality Level? If a process were producing 91 DPM, what would be the 6-sigma quality Level? Problem 7 Use Table Il Six Sigma Failure Rate Table to answer the following: 1. What is the short term if DPM equals 159.15? 2. What is the 6-sigma quality level with 1.5 o process shift if the DPM equals 66810.63
