Hello all,
I've been challenged by my boss to review if what we are doing to measure our process in correct.
Currently we are using DPPM. The problem I have with the way we do it right now is that we calculate DPPM = total number of defects / total number of produced units * 1 000 000. This way we can have more defects than produced units so the DPPM number will be higher than 1 000 000.
For example, if I want to build 10 cables with a terminal and the machine that crimps a terminal into a cable throws away 10 terminals during the process then I will have 10 defects and 10 produced units so the DPPM will be 1M.
Is this correct? It seems to me that this should be trated in a different way.
What do yo think about this? Any help will be appreciated
Thanks,
JP
