It's funny how government contract awards go. Losers whine and if the RFP hasn't been properly documented, vetted and scored then bidders can and have overturned decisions. It can even wind up in court based on federal procurement laws. In some cases fraud or collusion is involved while in others despite having an open process, a selected bidder can have an easier path through the process. The latter being the collusion part. For example a department writes an RFP and it goes out to bid for a new computer system that must be natively compatible with IBM's iSeries. Let's count how many bidders there may be.
This is how you get overly priced items built for the government. It drowns in paper and bureaucracy including the annual "spend the budget" fun of summer where government agencies spend unused money on anything and everything because they don't want to risk the upcoming fiscal year budget. Rather than waving or giving the budget back to the treasury they'll spend it on anything they can.
In reading the TFA it sounds like Lockheed did indeed come up with an overpriced system that had features that NASA didn't want. In reasonable cases that'd be it but all of the government contractors, not just aerospace, know how to game the system to the determent of all US taxpayers. It'll be fun to see if this gets dragged out. Fortunately there's two years until the next contract period and if Lockheed ultimately wins, the current contract holders will probably get paid at an escalated rate to deliver resupply missions because it'll be in their contracts as well since it's outside the agreed upon contract duration.
