In sum, the committee says, "Cover Oregon failed for two main reasons: The state acted as their own system integrator (like HeathCare.gov), and the state tried to revamp its entire health care system, not just build an exchange."
Seems to me that the state had more to do with it than Oracle. I am sure you are great at making "simple credit card web app" but if you have ever done anything with healthcare in the US it is a nightmare. And yes I currently work building software for healthcare in the US at a state level.
So they're paying millions of dollars for Oracle to claim they don't know how to do it? Maybe it is Oracle's fault after all... sales says "ok, we'll pad the budget, but it should be dead simple" and then implementation teams come in and realize they were actually undersold and then begin trying to suck all the blood out of a walking-dead project.
Oracle is at fault here for saying they knew the fuck what they were doing.
