He emphasizes a variation of the cost benefit formula + urgency, called Cost of Delay for prioritizing that basically boils down to "Value / Time Remaining" because your cost is the time remaining. It naturally prioritizes work based on shortest time to value because, unless the value proposition is enormous, dividing by estimated time is almost always going to favor the shorter tasks.
This will of course vary by team, but in general it puts a focus on responsiveness and getting the little stuff out of the way first (including tech debt). When you have a formula that doesn't let the little stuff build up, it gets easier to focus on the big stuff too. It's also make it easy to pivot because it totally disregards prior time investments.
It meshes better with what agile is supposed to be better than any other methodology that I've encountered to this point.
