Given the types of documents we in engineering deal with.  Be it SolidWorks documents or Inventor  or AutoCad.  Or MS Office or MathCAD.  What is your experience with Serial Numbers?  I was planning on using initial Development Numbers (Sandbox Numbers) that get switched out to Production Numbers but the complication with that is I wanted to uses the Designers initials as part of the Development Number.  No biggie except the Sandbox is shared between all users on any given project so I would need to write a Serial Number Addin to determine whom the users is requesting it.  Obviously a big issue with the Development Numbers is that to rename I would need to Move them from a Development folder to a Production folder and have the accociated data Cards set up calling different Serial Number Generators.

Then comes the issue with Items versus Files.  I can obviously generate Production Item Numbers easy enough but the Files should match.

How are you doing this sort of this?
