I'm interested in understanding where the users are spending their time. Are users "living" in SP and posting to Jive or vice versa.
Are they using sharepoint versioning? If so, how?
How is Jive/SP affecting email usage? What percentage decrease of email are they seeing with Jive SharePoint integration compared to the "old fashion" way of emailing everyone? Are users still relying on email to communicate their docs? Has there been a ramp-up period?
Are they using Sharepoint as the exclusive repository or are they splitting between storing in Jive and SP?
