Ries maintains that entrepreneurs, existing companies—or anyone trying to create something new and innovative—must find ways to constantly experiment and quickly put new ideas out into the world for public consumption, rather than devoting extensive resources and time to trying to perfect ideas behind closed doors. Ries urges businesses to focus on developing what he calls “minimum viable products”—in effect, quick, imperfect test versions of ideas that can be put out into the marketplace in order to learn what works and what doesn’t.
