As our Canadian contributor mentioned a few weeks ago, this was the same firm involved in Canada's long gun registry and they were ultimately using their contracts with the Canadian government as a money siphon to the Liberal party there. So they were awarded a $600+ million project with the US Federal government, and where do you think a big chunk of that money is going? Cue Jeopardy theme music.
As for the technical problems with the system, there's simply no way this is the result of incompetence and oversight. Not something of this scale with as much money involved. This IS the "working" design, if you will.
