One of the most interesting bits to me was something said by Todd Park, a former CTO of the US and still a White House advisor. I was, frankly, suspicious that Washington's culture could really accept a lot of the Agile and Lean notions that are commonplace in the high-tech world. But he pointed out, correctly, that waterfall projects are enormously risky. A big reason Lean Startup advocates place such a strong emphasis on frequent small releases is that it helps us reduce risk by finding and fixing problems early. He pointed out that if bureaucrats really want to play it safe, using agile, iterative approaches is exactly what they'll have to do.
I don't know enough about Washington to say if this really will work, but improving government efficiency through smart use of tech strikes me as exactly the kind of thing people from all parties can get behind. I'm excited to see how it turns out.
