The broad notion is that private-sector IT culture has undergone major change in the last couple of decades. The failure of HealthCare.gov under the old model and its subsequent turnaround using the sort of modern methods common in Silicon Valley woke people up to the possibility of doing something new.
The question, then, is how to get government working like we do. (At least where it's beneficial; we solve a lot of our mistakes by shutting down companies, but government departments can't work like that.)
A number of things have been tried, starting with the Presidential Innovation Fellows. [1] The US Digital Service is the latest pass. The USDS HQ is under the US CTO, which I believe makes it part of the Office of Science and Technology Policy [2], which is part of the Executive Office of the President [3]. The agency teams are embedded in the agencies themselves, and so I'd assume those are legally under the appropriate cabinet secretaries. I get all this mainly from the USDS pages. [4]
Personally, I suspect that this is not a lot of money. It's mainly people, and they made clear that they will be paying industry salaries, not government salaries. And given that it is getting government to reduce waste and learn from the private sector, I expect it has bipartisan appeal.
Even if the next administration dissolves it all, though, I expect it will still have a fair bit of effect. As anybody in the industry knows, the switch from 18- to 36-month cycles to 1-4 week cycles is pretty much permanent because the culture has shifted. People just expect stuff sooner now.
But I hope the next administration continues the effort. At the meeting it was clear there were a lot of people in tech who really want to go serve their country by taking a couple years to make the government run better. It'd be foolish not to take advantage of that yearning for public service.
