One of the leading business thinkers in the world offers a bold, new theory of advanced leadership for tackling the world's complex, messy, and recalcitrant social and environmental problems. Over a decade ago, renowned innovation expert Rosabeth Moss Kanter co-founded and then directed Harvard's Advanced Leadership Initiative. Her breakthrough work with hundreds of successful professionals and executives, as well as aspiring young entrepreneurs, identifies the leadership paradigm of the future: the ability to "think outside the building" to overcome establishment paralysis and produce significant innovation for a better world. Kanter provides extraordinary accounts of the successes and near-stumbles of purpose-driven men and women from diverse backgrounds united in their conviction that positive change is possible. A former Trader Joe's executive, for example, navigated across business, government, and community sectors to deal with poor nutrition in inner cities while reducing food waste. A concerned European banker used the power of persuasion, not position, to find novel financing for improving the health of the oceans. A Washington couple enticed global partners to join an Uber-like platform to match skilled refugees with talent-hungry companies. A visionary journalist-turned-entrepreneur closed social divides by giving fifty million social media users access to free local education and culture. When traditional approaches are inadequate or resisted, advanced leadership skills are essential. In this book, Kanter shows how people everywhere can unleash their creativity and entrepreneurial adroitness to mobilize partners across challenging cultural, social, and political situations and innovate for a brighter future.
