Question: Suppose you have a 3 step process. The first process has a 3% scrap rate and a 5% rework rate for a first pass yield
Suppose you have a 3 step process. The first process has a 3% scrap rate and a 5% rework rate for a first pass yield of 92%. The second process has a 2% scrap rate and a 4% rework rate for a first pass yield of 94%, and the third process has a 3% scrap rate and a 8% rework rate for a first pass yield of 89%. Of all raw materials entering the process, what % will eventually be ready for sale? What is the rolled throughput yield (RTY) of the process and what does it mean? What is the overall scrap rate? Show your work.
