The global development community is teeming with different ideas and interventions to improve the lives of the world's poorest people. Whether these succeed in having a transformative impact depends not just on their individual brilliance but on whether they can be brought to a scale where they reach millions of poor people. Getting to Scale explores what it takes to expand the reach of development solutions beyond an individual village or pilot program so they serve poor people everywhere. Each chapter documents one or more contemporary case studies, which together provide a body of evidence on how scale can be pursued. The book suggests that the challenge of scaling up can be divided into two solutions: financing interventions at scale, and managing delivery to large numbers of beneficiaries. Neither governments, donors, charities, nor corporations are usually capable of overcoming these twin challenges alone, indicating that partnerships are key to success. Scaling up is mission critical if extreme poverty is to be vanquished in our lifetime. Getting to Scale provides an invaluable resource for development practitioners, analysts, and students on a topic that remains largely unexplored and poorly understood.
