In earlier work, PPPLab has identified ten ‘ingredients’ or building blocks of scaling strategies. This study looks at success factors for effective scaling processes. It focuses on how to shape the process: process dynamics, leadership, and the ability to act and relate, rather than on ‘what’ to address and achieve. What are the essential capabilities of those that lead the scaling process? How to make use of system dynamics in your scaling effort? How to partner in the most effective way to make scale happen?
