There are sophisticated schools of decision making in places like Harvard, West Point, Sandhurst, etc but peel the onion and at the core is always this framework that is incredibly successful with all things we “make” – buildings, dams, bombs, computers, genetic engineering – NASA put a man on the moon using this framework. However if honest we note the core framework is less successful with things we “manage” – economies, agriculture, desertification, climate change, etc. The former are termed “complicated” and the latter “complex” in Systems Science jargon.
