This is a great article pointing some important areas leading to team work spirit within a DBA team and providing superior professional services to an organization for a DBA team.
A DBA team needs to establish proven and consistent procedures to perform support. The purposes for these are to inform the involved parties for a database change to take place, to obtain required responsible parties' approval for a change, and finally to ensure a change to be well integrated into the current application.
Any DBA team members who can solve tough architectural and technical problems are certainly great asset for a DBA team. However, heroes building up with "short-cuts", "back-door" practices, and the like are certainly leaving changes without necessary tracking, undesirable for applications of established organizations, and away from team spirits as well.
Thanks Craig for your nice article!
