“…This resulted in a list of factors that various authors have posited as important or necessary for successfully scaling up and/or out from a pilot stage (Rogers, 1962(Rogers, , 2010Rogers and Shoemaker, 1971;Granovetter, 1978;Kemp et al, 1998;Kern et al, 2001;Moore, 2002;Gershon, 2009;Rosenberg, 2011;World Health Organization ExpandNet, 2011;Management Systems International, 2012;Ardoin et al, 2013;Butler et al, 2013;Sutton and Rao, 2014, UNDP Small Grants Programme, Stanford ChangeLabs, unpublished). While some of these authors cited real-world examples of scaling success throughout their papers (Kern et al, 2001;Rosenberg, 2011;World Health Organization ExpandNet, 2011;Management Systems International, 2012;Ardoin et al, 2013 UNDP Small Grants Programme), the discussion of which factors were most important to ensure success were largely theoretical. Furthermore, we found no empirical evaluations of the association of these factors with scaling success.…”
