Question

A process step produces the following data: the total number of units processed equals 50 units, and the total number of actual defects found equals 7. What is the "throughput yield" for this process step?

Answer 1

The throughput yield for this process is equal to $e^{-DPU}$ (DPU meaning Defects per Unit) DPU=Total of defectives/Total of units

So:

$DPU=\frac{7}{50}$=0.14

Throughput yield= $e^{-0.14}=0.869$
