True, but nothing compares to government for the sheer magnitude of costing errors. Back in the 1980s, I was on the receiving end of a satellite operations system developed by IBM. It was bid as an $80 million open-ended project. Years late and $800 million later, we finally received a system to do satellite operations. It was a buggy mess but what's a 1000% overrun between friends? There are other examples of government projects that run several hundred percent over budget, and the Big Dig proves it isn't limited to high tech or military programs. Corporations can and do experience overruns but they seldom let things get so far out of hand before either restructuring the project or killing it. I do know of some DoD projects that were killed for going over budget but the number is very small.
