Product Judgment isn’t an obscure concept. It exists, it is verifiable, and it is learned through direct experiences with customers.nYou can increase the speed at which you build Product Judgment by talking to, and observing, more and more customers.nBuilding a great product crosses many domains, and Product Judgment is domain specific. The domain might be the industry the product is in, or the type of problem it solves. Or the domain might be the different areas that make up a full product, from how it is designed, to how it is priced and positioned in the market.nProduct Judgment is transferable across similar domains, but not across different domains. To build fully rounded Product Judgment, you need to cover the wide range by directing talking to customers about all the domains.
