Best practices for tagging new files

• Trying to get staff on board to tag newly-created files in SP.
• We're recommending that staff create new documents in SP (rather than creating a document in Word on their machine and then uploading it).
• The following is the simplest way to do that, as far as I can tell. (It seems very clunky; hard to believe it's the best method.)
  • Create new document (or other file type) in SP.
  • Change the file name.
  • Close the file.
  • Select "Edit in grid view."
  • Add metadata.
  • Close grid view.
  • Reopen the file.

Is this really the smoothest method? It just isn't intuitive to require a user to close a file they just created.
