We regularly hear from organizations that are using or thinking about using a product data management (PDM) solution such as Autodesk Vault or SolidWorks Enterprise PDM (EPDM) to manage their CAD drawings and parts (items).  Users want to know how these PDM applications fit into a PLM strategy.  “Does PLM replace PDM?”  “Should we stop the PDM evaluation process and just go to a PLM solution?”  “We implemented PDM, but the company wants to implement PLM.  Our CAD users don’t want to change.  Can they work together?” For starters, there is a role for each solution.  It is not a question of one-or-the-other.  Coexistence can be a preferred strategy for certain situations.
