Relying on experience from a single domain is limiting. Going from the “inside view” to the “outside view,” i.e., switching the mindset from narrow to broad, is the practice of looking outside of the surface features of a project for structurally similar analogies.
The power of making a multitude of analogies from varied domains is what leads to coming up with solutions, and successful problem solvers are more able to determine the deep structure of a problem before matching it with a strategy.
