I work with some people who used to work for RBS IT, they tell me that the department was as bureaucratic as they come (presumably to reduce risk) but once all the hoops had been jumped through, it came down to single team who would put code into production, and they were often quite poor at it.
When I think about the scale of this mess, and the hundreds of millions that RBS is going to loose in compensation and lost customers, I hope that RBS (and in house corporate IT in general) starts to appreciate the need for automated deployment and fault tolerant IT systems rather than yet more process as the answer (I'm looking at you ITIL).
