The Wikipedia article you posted is very relevant to me because I watched a division of the Air Force waste tens of millions of dollars trying to implement that approach for their collection of IT systems.

The consultants got very rich with their cartoon drawings on the walls and nothing was produced for the taxpayers naturally.

A complete failure but because it's the federal government nobody was held accountable and the person in charge changed the success criteria enough to be able to cancel it and call it complete.
