Keeping track of shared documents has historically been a challenge with cloud services aimed at single users with shared documents. As staff arrive and depart, documents and links can be lost when their drive is moved or removed.
Drive for teams will enable staff to share documents in a central location, with content ownership and sharing managed at the team level. Add a new staff member to the team and they instantly have access. Remove a member from the team and all of their work stays in place.
Google Drive for teams is coming soon, with a preview available through the G Suite Early Access Program.
