Hmmm, well there could be lots of reasons but an obvious one, at least to me, is that staff need to go get their heads around a new way of building systems and then they must build the new stuff and maybe integrate the old stuff too. If after several project's it's still more expensive then: (1) They mightn't be getting the benefit they thought they would (2) Their staff just can't cope with the new methods (3) The new tech they're using isn't up to much .......
