Product Definition Knowledge Management (PDKM) is a solution architecture approach that guides the use of PLM in supporting the full lifecycle of a product.  The purpose is to have all the relevant product information in one place, connected to meet business needs, and safe.  In other words, PDKM is a single source of the truth.  The PDKM solution covers the product definition scientific and engineering information from the earliest research through all the improvements made to the product and its manufacturing process until the end-of-life.

During a recent business trip, I was sitting in an airport café with some colleagues while discussing how to build and manage BOMs.  We got some strange looks.  Then I mentioned something about exploding the BOM.  More strange looks.  Nervous glances.  Finally, we decided it was best to avoid using the B word in airports.  But since you probably know a thing or two about BOMs and PLM (otherwise, uh,  why are you reading this?), I'll assume you know what I'm talking about and I can use my normal Nerd-speak of PLM acronyms.  (My nickname around the office is "Big Nerd", because I'm six foot four and I think BOMs are interesting).
