While I agree that sys admin actions on production machines should be tracked, as a developer I wish there was an easier solution to logging user behavior. It has been a few years, but shortly after Change Data Capture became available I was building an application where we wanted to track who changed what. The DBA thought this would be a great place to try out CDC. It all seemed great -- until I needed modify the schema. Then all that goodness silently broke leaving no tracking. This to me is the kind of story that just shouldn't happen.
