"I really have trouble understanding the big 4 consulting model. It mainly seems to consist of the following" I think that, as with enterprise software, is mostly about the management in the customer company trying to cover his/her ass. Big four and similar are the less risky options, not for the project but for the managers. 'Yes, the project was a disaster, but I hired IBM, so, no responsibility here.' Of course, the management of the customer and the consulting companies are normally old friends. That helps too.
