We have learnt what is First pass yield and throughput yield in previous articles. But, in those articles we have only considered one process, since we are just started to learn. Let’s learn to calculate first pass yield of whole process of a product which have more than one processes.
Let’s start…
So, if there is more than one process how will we calculate First Pass Yield (FPY) of whole process together ?!
Don’t worry it’s not that complicated….
Just multiply individual process first pass yields.
First pass yield calculation example
Suppose a product has 3 processes and individual first pass yield of each processes are 60%, 70% and 90%.
Now FPY is equal to,
60% x 70% x 90%
= 37.8 %
That means if we pass 100 products through this processes, only 37.8 nos will come out of the processes initially as good products.
That’s it we have done the calculations.
Thank you.
