Production DBAs roles in different groups under a DB Manager

I am curious to know how some of the big organizations have their DB org
structure from an Operations perspective
Can someone let me know how its done in your organization and how it has
helped ? I am looking for the different groups under say a director/manager
of database operations ?
Thank youWe are spilt into 3 groups: Adabase, DB2, and SQL server. One of the DB2
guys dabbles a bit in SQL (maybe assist with migrations, easy data
transfers, etc.) which has been nice on busy days.
I was on the phone yesterday though with a company that is also split into 3
groups: Development, QA, and Production. I would guess this greatly reduces
the amount of people that need security rights to production boxes.
