<P> Suppose a process had 3 steps . Step 1 produced 10 units and 2 were defective, the yield of step 1 would be 8 / 10 or 0.80, Step 2 had a yield of 0.9 and step 3 had yield of 100% . The rolled throughput yield for this entire process would be: </P> <P> RTY = 0.80 * 0.90 * 1.0 = 0.72 </P> <P> RTY = 72% </P> <P> The probability of this 3 step process producing a defect free product is 72% </P>

Compute dpu and operation yield for each step. determine the rolled throughput yield
