I don't know what ISO 9000 says but here is my theory:
We have a low volume product that sometimes uses parts that are the same
as
in another product but we refrain from re-using the same part number
across
projects. The reasoning for this is what if the part has to be revised at
design or in the future, this now changes the part for all jobs it was
used
in. There is a specification for defining when a part gets a new number
but
I feel it is just to dangerous and prone to errors, ie: someone not
realising where else the part is used and changing it. So we just do a
save
as and give the part a new number for the new job.
For comman parts ie; nuts screws etc we have a system similer to the
previous poster.
Again we produce low volumes so this makes sense for us it may not for a
different situation.
