From my point of view, outages are caused by:
1) operator
2) software defect
3) hardware defect

From my experience now days the likelihood of an outage as a result of 3) is
magnitude less than 2) and same goes for 2) to 1) ratio. 
In other words the vast majority of the outages are caused by human error. 
One way to partially rule out 1) is to have a fully customized stupid proof
provisioning system - customized by those who know how stuff works.
