True, I've seen programs heavily underbid and staffed with recent college grads with very little programming knowledge. The goal was to produce non working product to then milk the O&M contract for years and years.
Accenture, IBM, Booz Allen , Lockheed Martin , SAIC are all very similar when it comes to large project execution. The name of the game is to win a proposal by any means necessary then control the costs. In a large project it is never about the developers, what makes or breaks a large gov project is the quality of the functional analysts and tech management. If conflicting reqs and features can be argued down the proj will succeed.
