Do you give sysadmin rights to a DBA's regular LAN ID? We only grant admin rights to special ID's that aren't used for anything else. That prevents a bunch of mistakes, and provides the appropriate SOX cover as well. We make sure that no ID has admin rights on both a test/development box and a production box, which prevents anyone from accidentally running tests against a production database. We also have a separate acceptance environment that is set up hte same as a production box, with limited access for developers and support personnel. All actions on the aceptance environment are done by a DBA/Server admin just as would occur on a production box. This ensures that installs and upgrades to apps and databases will work. Nothing goes straight to a production box - all changes must go through acceptance first.
