Beginning with the end in mind: planning pilot projects and other programmatic research for succesful scaling up
Pilot projects and other programmatic interventions in which health innovations are tested on a small scale often show impressive results. However, their influence tends to remain confined to the original target areas and their results are often not sustainable. One of the reasons for this failure is that the requirements of large-scale implementation are rarely taken into account at the time of pilot- or field-testing.
