The UKs NHS IT programme attempted to centralise patient records and its going "oh so well". Its (IMO) a good example of where IT tries to work against the existing service models and ways of working. Of course patient data needs to be shared, it is shared today, but maybe the right way to do it is share it in-context rather than centralising it. A business centric view helps you answer that, an IT centric view helps you create an "optimal" IT model that might in fact be useless to the business.
