Simon points to computer-driven woe at the Royal Bank of Canada. They have 155 people working on the problem.
In the olden days, I used to work at a bank. They ran their entire transaction processing load on a brand new IBM 4341. One pension day, something really bad happened, and in the space of two minutes, the computer room filled with people.
They arranged themselves thusly:
I know all this because I was visiting some of the other operations staff at the time, and was left to watch the scene unfold through the plate glass windows. Pretty soon, the area I was in filled up too.
I looked around, decided that no good could come from watching a disaster unfold, and made myself scarce.
