UFFDA!
I've used Vantage for a total of about 10 years at 2 different companies
and Side A made me shudder! I'm currently at a medical company, and we LOVE
to make things as complicated as possible, and WE haven't even considered
that!
You asked "What are the ramifications of creating part numbers for each
process step?" I can think of a few...
Number 1:
How does he propose to make Vantage change part numbers at every step?
Maybe I'm blanking out a third option, but the only two ways I can think of
to change part numbers at a manufacturing operation are to make EVERY
operation step a subassembly of the one before, or to make every step a
different job--both options sound like a nightmare to me!! Plus, you said
you have some 2 level BOMS, you would lose the obvious manufacturing levels
of those BOMS--they'd only be visible by part numbers or prints. Besides,
your production controller might have something to say when they find out
how much extra job paperwork they would have to do.
Number 2:
How does he proprose to "define" each of these part numbers?
By this I mean----Generally at most companies, each part number is defined
by a print, specification or something else that says "this is the criteria
this part needs to meet when you have completed the operations to create
it". This will obviously depend on how your company defines part numbers.
My company would have to have a print or a material specification, and
inspection documents for every part number. Once again, a complete
paperwork nightmare for Quality and Engineering if they had to create
something for every operation. Also depending on if you're certified to
something (ISO 9000, etc.) your Quality Group might also have some input on
what he would need to have for each part number to be "legal" within your
Quality system--this might dissuade him, as well :-)
In general, we usually only create manufactured part numbers for three
reasons...
1. If it makes sense to stock at that level (i.e. common part that can be
used on multiple parts)
2. It makes sense to break up the manufacturing so we can define what it
should be at that level (i.e. we manufacture components in one area, and
assemble them in another. We have separate part numbers for the
manufactured components because we want to make sure that they meet certain
criteria, like a subassembly drawing, before they go on to be assembled.)
3. Finished goods part number to sell to the customer.
Hope this helps! (Sorry for the long-windedness!)

Subject: [Vantage] Soliciting Comments on Job Setup
We are having a philosophical discussion regarding Job Setups and Bills.
Conditions: 1 or 2 level bills are the norm, 3 to 4 job operations are the
norm, Version 5.0
Side A:
Says that a part number needs to be created for each job step so that WIP
amounts processed can be tracked. IE; as part abc1 moves to operation 2 it
becomes part abc2, as it moves to operation 3 it becomes part ABC3 and so
on. This will necessitate the creation of a part number in the part master
for each process step, so that materials management will know how much
material is in each step.
What are the ramifications
of creating part numbers for each process step?
