Where I work, at a mobile ad network, they put everyone on call on a rotating basis even if they are not devops or server engineers. We use Pager Duty and it works well. Since there is always a primary and secondary on call person, and the company is pretty small and technical, everyone feels "responsible" during their shifts, and at least one person is capable of handling rare, catastrophic events. I often wonder which is more important: good docs on procedures for failure modes or a heightened sense of responsibility. A good analogy may be the use of commercial airline pilots. They can override autopilot, but I am told rarely do. The safest airlines are good at maintaining their heightened sense of vigilance despite the lack of the need for it 99.999% of the time.
