Scaling aims to increase the use of innovations (new technologies or practices) to impact many people. At the same time, scaling should also lead to a sustainable system change in which the impact remains, or even accelerates, without further special project or donor interventions. Successful scaling of innovations requires that at least as much attention is paid to the complementary non-technological requirements. These non-technical requirements form the basis for the Scaling Scan, which is built around 10 “Scaling Ingredients” that each require attention to reach a scaling ambition.
