Meeting workspaces, version history, bulk tagging.
Improvements to My Organization:
It has helped us collapse all our versions into a single file. It has also improved our meetings.
Room for Improvement:
Setting up permissions can be overwhelming. If this can be improved it would be great. Also Sharepoint search out-of-the-box needs improvement.
Use of Solution:
Five years. Started out with Sharepoint 2007.
Most issues are from the change management part.
The solution appeared unstable at deployment but it's been more stable since then.
We implemented through a vendor team.
