When I was doing disaster recovery we measured three things: 1) the likelihood of a particular scenario, 2) the magnitude of the impact if the scenario unfolded, and 3) the level of effort expected to recover. It was the combination of these three things that prioritized decision making.
We were working towards a business continuity plan which can include incidents like your main office and operations being destroyed and having to quickly relocate all services to 3rd-parties using off-site backups with minimal staff. While that was a worst-case, a primary focus was just getting a notification site up and running in the event of a network outage because that was vastly more frequent and had high visibility.
It was a very interesting project and I learned quite a bit about how to think comprehensively about the solutions we provided.
