Two words: Change Control

Some change controls inherently have no or poor backout alternatives. Soemtimes you can perform what looks like a perfectly good Change, and the problem doesn't show up until related systems are on for twelve hours and try to execute something that no longer works. Besides that, some Change Controls do not account for all stakeholders until it is too late. Backup admins are inexplicably left out of the loop all too many times.
