Of 3,555 projects from 2003 to 2012 that had labor costs of at least $10 million, only 6.4% were successful. The Standish data showed that 52% of the large projects were “challenged,” meaning they were over budget, behind schedule or didn’t meet user expectations. The remaining 41.4% were failures — they were either abandoned or started anew from scratch.
On the other hand, we should all trust that the biggest IT project in the history of the world, the NSA, is error free and perfectly trustworthy.
Of course, all its failures and screwups are top secret, so we’ll never know.
