I've had to do this. When there's SLAs / money involved for failure,
you can't cowboy anything - because you're risking your job if you do.
Funny thing is, going through a "rehersal" before you make any change
increases significantly your chances of success - and now I prefer to
plan my changes in detail before I do them, as it makes me look a lot
better at my job.

A firewall change in particular, because of the security consequences
of mistake, justifies planning and review before implementation.

Regards,
Mark.
