That right here is the meat of so many issues in large IT projects: large corporations or government are very, very skeptical about changing their "established processes", usually due to "we have always done it this way". And no matter how often you try to explain them "do it a tiny bit differently to get the same end result but MUCH more efficiently" you'll always run into walls.
