Design teams need to manage and revision control files, but to go further with PLM you need to understand what processes you want to support before you know what data you need in the first place. Process drives the requirements for data.
Job one for successful PLM is to get the data, not just CAD and other files but information, centrally accessible and secure. If processes are enabled in PLM by poor data, decisions will be impacted negatively.
