Good article, What if I know only the population size (!000 for example) and I don’t know the Sigma Value ?
How can I calculate the sample size ?

Hello Syah;

We use Rolled Throughput Yield (RTY) to monitor each Sub Process and to see the rework (Waste).

For the whole process, we use FTY to show the Accepted output / Total Input.

Thanks

Actually, I’m confused because when I read this article and compared it with the below one regarding to FTY Calculations;

Appreciate if anyone can correct me if I’m wrong.
