What makes great nonprofits great? Not large budgets. Not snazzy marketing. Not perfect management. The answer is not what you might think. Great nonprofits spend as much time working with institutions outside their four walls as they do managing their internal operations. They use the power of leverage to become greater forces for good. This landmark book reveals the six powerful practices of 12 high-impact nonprofits and tells their compelling stories. Leslie Crutchfield and Heather McLeod Grant spent four years surveying thousands of nonprofit leaders, conducting hundreds of interviews, and studying in-depth a dozen high-impact organizations to uncover their secrets to success. Their quest took them from the well-known (Habitat for Humanity) to the less well-known (YouthBuild USA) and to the unexpected (the Exploratorium). What the authors discovered surprised them. How did seeing a pile of McDonald's trash lead Environmental Defense's president to join forces with business instead of treating it as the enemy? Why did a school bus driver prompt Self-Help Credit Union to move from serving low-income groups in North Carolina to launching a national advocacy campaign against predatory lenders? And how did Teach For America turn the teachers it places in underserved public schools into a national vanguard for education reform? At a time when the social sector has grown to more than $1 trillion, understanding what leads to impact is essential. Whether you're a nonprofit leader, philanthropist, business executive, board member, volunteer, or simply interested in changing the world, this book will inspire you to be a stronger force for good.
