I get the idea that more companies are getting away from the integration of the part number format into the document number format. For example, in older, best-practice companies, 123456 is the document number and 123456-03 is the part number designation. (Tabulated part-number methodology recommended by author Frank Watts.) The newer method would have a tabulated design number that might look the same as the tabulated part number (123456-03), but the part number related to the design 123456-03, might be 78912345… Author Dave Garwood champions this newer method.

My question relates to identifying numbers that physically appear on a spare part or spared assembly (assuming the newer method). I would guess that if the service department would want an identifying number to physically appear, they would want it to be the part number, not the design number. Does anyone have some insight and experience in this?

Our service requirements and aftermarket parts are based on the identification of the part number, not the design number. The part number defines the physical element the customer has in hand whereas the design number defines potential geometry and potential material only depending on customer requirements.
