"The lightbulb has to want to change."
So very true. The problem I encounter with any sort of "agile IT," "green IT," or anything even remotely innovative is the reactionary mindset of the copper-counters. There is, in their mind, absolutely no reason to spend anything...EVER...until a problem has arisen needing solving. Regardless of any business case you put forward, regardless of the potential or calculated savings, if what they have right now works, and any changes would cost them even a bent copper...there is no way we will ever be allowed to implement it.
It is for putting out fires. Not for preventing them. So sayeth the copper-counters.
