When Taiwan was designing their new health system in the 90s, there wasn't yet consensus on how it should work. And as anyone who reads Dilbert knows, when the decision maker doesn't understand the space, bad decisions are made. So, how to educate a decision maker?
"[We] had a conference in Taipei, over three days, and all these [experts] debated each other. And I required cabinet ministers [aka decision makers] in Taiwan to chair the various sessions, like the minister of finance, the minister of planning, of health. See, when you chair a meeting, you have to sit through the whole thing and listen. That's how you educate decision makers."
