Comments interspersed below... Joe's comments are generally right on, and I can provide some insight into how governments buy stuff (it's pretty strictly regulated.. far more so than in private industry, but some of the processes seem arcane and bewildering at first glance)

I agree. Here at JPL we have pretty stringent rules under which we can do things in terms of using the name of JPL or NASA.  Granted, nothing stops you advertising your product "as sold to NASA", but under no circumstances could we provide any sort of endorsement or recommendation.  We can co-author a paper or report with the vendor which reports information from some activity. We can say what we did, and make generalized fact based recommendations.

I agree here, too. My wife works in commercial IT, and I'd say that they tend to beat the vendors down more than we do here in government funded work.  She (and her bosses) have to report against monthly, quarterly, and annual targets for everything.  Government work tends to be funded on an annual cycle (October 1st is the FY start date.. funding gets set based on proposals in March/April, and cast into concrete around now for the next FY).  

Where government work is concerned, the problems usually aren't profit margin (we're happy to give a reasonable rate of return, because screwing the clamps down onto the vendor's last penny usually doesn't work out well.. they'll put their top people on the jobs that have decent returns, especially if your job gets into difficulties).  It's the myriad other weird and not so weird  conditions (Drug Free Workplace Act, Buy American Act, Foreign Corrupt Practices Act, etc.) resulting from the dual role of government procurement: get something useful done and create social policy. That, and the absolute paranoia that the taxpayer might be getting the short end of the stick results in a substantially larger paperwork burden to prove they aren't.  All those folks standing up decrying "waste, fraud, and abuse"... In a commercial entity, one can do a cost benefit trade on, say, inventory losses vs time/effort to keep track of things.  Not in government, when someone will be sure to !
 stand up and say "Agency X lost or misplaced 3 laptops out of the 123,000 they have, and this must stop now!"

Government work also often pays slow, but reliably.  But your bank may not understand, so getting operating capital can be a challenge.

Yes.. it makes *this week/month/quarter's* numbers look better, and also gets you out of having to seek capital (which has been hard recently in these odd-times for credit).

This sort of thing is often done under a "Cooperative Research and Development Agreement" or CRADA.  This is basically a contract between the govt and the vendor which lays out who is doing what, what they're bringing to the table, and where the intellectual property rights will wind up.  For example, I'm working on a space mission now where several vendors have provided equipment under CRADAs. I don't know anything about what's in the agreement, but in general, it's something along the lines of "we give you a ride into space and you get to fly your box and test your new technology"  International MoUs for science instruments also work this way.  For NASA this is all covered under the "Space Act"

You got that right.. You'd have to put a number on the prestige and trade it against someone's advertising budget.

Exactly.. we do this with "source selection" all the time.  The proposals are proprietary and confidential, the reviewers on the Source Evaluation Board all sign NDAs and go work in a special room where all the materials are kept. It's a very, very big deal (even for relatively small procurements).  Once the selection is made, then we shred all the materials, and go to negotiate the actual contract with the vendor (which can't change substantially from what they proposed, because otherwise the losing vendors can legitimately complain).  

During the negotiation process (especially if it is a cost plus fixed fee) the vendor will need to provide a lot of financial details to allow our people to determine if the price is "fair" and that the vendor is giving the government the "lowest price" (if you want to stay out of trouble, do not sell us something for $1000 and then sell it to someone else for $900).  That financial detail is generally proprietary (e.g. as a vendor you don't want us telling everyone how much your people are paid and how much you pay in fringe benefits) and wouldn't be disclosed, but the total contract value, and a fair amount of other information, is disclosed.
