Hello experts,
May be its a stupid question but I was wondering what's the best approach to calculate first pass yield of a manufacturing site if you have more than one production line producing different range of products?
Option-1: Calculate no. of batches produced at all the lines and check total failures to calculate FPY.
Option-2: Calculate FPY of each line then take average? .......wait a sec........ should we take average here or multiply FPY of each line to get total FPY(as what we do to calculate Rolled Throughput Yield RTY) , its really confusing isn't it?
Would love to hear feedback fromeveryone!
Thanks,
