Asking "what can possible go wrong?" is good. Believing that nothing can go wrong is suicidal.
No doubt you will still miss some failure modes, but looking for them and developing ways to deal with them will pay off in the long run. -- Shmuel (Seymour J.)

I was working at an HMO in California and troubleshooting a networking problem with the Network Control dudes. One of them thought that reseating a token ring cable would fix the problem. As he was reaching down I formed the word STOP when he deftly unplugged the cable and said, โThis will only take a second.โ In which second he took down all the call center 3270โs across Southern California. He said it was only a brief interruption. Management disagreed and instituted the NO cable work except during a weekend window with a change record even for troubleshooting.
