“…This kind of innovation process makes the measurability of innovation specially difficult, since it occurs in a disperse (even globally) way and distributed in a community. As a result, the most salient surveys on FLOSS production take as observational units the software workers and developers collaborating in community projects: the WIDI 2001 survey (Robles, Scheider, Tretkowski, & Weber, 2001), the BCG Hacker Survey 2002 (Lakhani, Wolf, Bates, & DiBona, 2002), the FLOSS 2002 survey from UNU MERIT (UNU MERIT & Berlecon Research, 2002), the UNGS-SADIO 2004 survey (Borello, Erbes, Robert, Roitter, & Yoguel, 2005;Borello, Robert, & Yoguel, 2006;Robert, 2006), and the survey from the FLOSS WORLD 2007 project (MERIT, 2007).…”
