In my current company one team is responsible for the Automic System (actually 2: PROD and DEV) and the Components & Processes needed for it (DB, Agents, Reorg, etc...)
every Department is responsible for its clients on these both systems for development and deployment of code, etc.
we have some guys that own a special role that help you if you have questions how to implement or code something - someday I will be part of this team :-)
