The situation where you have a bunch of people trying to make a name for themselves within a project perceived to be very important without one strong decision maker keeping everyone in line is my number 1 "project smell" for detecting likely failure of a big project, and I'd be surprised if this wasn't a factor in the failure of the HealthCare.gov site.
