I’ve been in IT since the early 80’s. When I heard how much this effort cost, my jaw dropped. The cost was absurd, by a couple of orders of magnitude.
And that is assuming that the final product would have worked well.
The more money they say they need to " fix it " the more we know it really has problems and will not be able to fix.
When you look at it ? it might be just a slush fund.
Congress really needs to investigate just where all that money really went.
