As long as IT seems and is held to be a different part than the business any communication must fail.
IT must be part of the business and aligned to the business goals or it will be a drag to the business.
As for history:
Probably a good part of why the Third Reich never lasted 1000 years was the misalignment of goals between Hitler and Halder.
Also a very neat display of how business goals can be re-interpreted (by Halder) to the point of becoming something else.
And the good thing was: The operational goals were drawn up well before the operation started. Talk project scope creep and misdirection at high level before the project even gets underway.
As if New Order of Europe and The Final Solution were public works projects that simply got way out of hand. :unsure:
