> It also hammers home the idea that you need backing and buy-in from key players in the workforce before everyone else will follow.

Yup, this is the key issue and what makes it primarily a people problem. Technical solutions don't work if the main problem is getting buy-in to spec/build/adopt one, unless you're willing to build a lot of things you end up throwing out. So instead the bulk of the high risk work is actually negotiation between people.
