And every single part of that "rescue" would never have been needed if the original team had been allowed to "do things the normal standard way" the first time. We can guess the reasons - everyone and their dog wanted to be part of the flagship IT project, a slew of conflicting interests and parties who would not talk to each other or in some cases were actively sabotaging efforts, a failure to recognise that "working complex systems only ever evolve out of simple working systems". Why do we always do this to ourselves ?
