Honestly, having worked in corporate IT, a project big enough to last for 5-10 years has an enormous amount of inertia behind it from the tens or hundreds of people in the company who got behind it, all the "ra ra" project newsletters, the political capital expended to get the project budget approved, etc..
Even if it was going absolutely terribly and wasting millions of dollars, the project sponsor has every incentive in the world to keep moving forward and try to get something out of it to justify all of that. The failure of a big project like that might kill somebody's career at that company; a lackluster deployment a few years behind schedule is survived more easily.
