"Back in the day" I identified a way to save prob a quarter million dollars a year on my project, funded with your tax dollars. Created a spreadsheet model for the cost, documented it all, and gave it to my boss. He said "I'll look it over". I asked his two weeks later if he'd been thru it. His response was "It looks correct. Nice job." I asked if were going to trial it.
Golden response: "No, we don't get paid to save money; we get paid to spend money."
And that is when I truly understood Cost+Award Fee contracting with the gov't.
