It's exactly like properly/cleverly documenting your code/project: not only for others now or in a few year, but also for yourself later on.
It's having common rules across teams to get more reliability out of the whole company.
You build it, you run it. Fine. Until the point when you can't anymore (because... reasons - it just happens). In any activity you want to sustain, you always have to have backups (in people and in processes), instead on relying on your-(self/team) alone.
