From One to Many: Scaling Up Health Programs in Low Income Countries addresses both problems and opportunities in scaling up health programs: It gives voice to the too often unheard program implementers and articulates their rarely found details and hard-won insights about the step-by-step negotiations that determine the success or failure of bringing programs to scale. At the same time it delivers the critical analysis and the breadth of perspective of academic writers who have studied scaling up efforts across the globe. It also provides the unique perspective of those with a foot in both the worlds of implementation and academia. This collection serves both as a guide book for those working on the ground scaling up health programs as well as expanding the discourse about different approaches to implementing and evaluating the process of scaling up.
