In this great article on the IT project fiasco in Mitt Romney's campaign, there's a quote that is representative of much of what you see around many IT projects:
[...] I had some serious questions—things like 'Has this been stress tested?', 'Is there redundancy in place?', and 'What steps have been taken to combat a coordinated DDOS attack or the like?', among others. These types of questions were brushed aside (truth be told, they never took one of my questions). They assured us that the system had been relentlessly tested and would be a tremendous success."
