Today’s fastest growing, most profoundly impactful companies are using a completely different operating model. These companies are lean, mean, learning machines. They have an intense bias to action and a tolerance for risk, expressed through frequent experimentation and relentless product iteration. They hack together products and services, test them, and improve them, while their legacy competition edits PowerPoint. They are obsessed with company culture and top tier talent, with an emphasis on employees that can imagine, build, and test their own ideas. They are maniacally focused on customers. They are hypersensitive to friction – in their daily operations and their user experience. They are open, connected, and build with and for their community of users and co-conspirators. They are comfortable with the unknown – business models and customer value are revealed over time. They are driven by a purpose greater than profit; each has its own aspirational “dent in the universe.” We may simply refer to them as the first generation of truly responsive organizations.
