“…Mainly the measurement of scientific productivity has been based on indicators of scientific publications, patents and awards (Goel & Göktepe-Hultén, 2019; Ribas et al, 2015), but when relating scientific productivity to the performance of RG the relevance to the group's size on performance and productivity is evident (Rey-Martin et al, 2008; Rueda-Barrios & Rodenes-Adam, 2016; García, 2019) where there is not always a positive correlation between these two factors, however, it is wise to establish a unit of measure that explains and compares the level of productivity based on the size of the RG in Colombia as a way of sizing individual activity. Mod et al (1984) considers that the production of RG is due to factors related to short-term impact, long-term impact and a quality notion, understood from cognitive, methodological, aesthetic quality; in turn, other determinants of the performance of RG are related to strong leadership, strategic direction, skills and human talent, complexity of collaboration focused on the subject, diversification and entrepreneurship (Harvey, Pettigrew & Ferlie, 2002), as well as co-authorship (Garner et al, 2018), in addition Brew et al (2016) compiles institutional characteristics variables, academic abilities, workload, time of dedication and communications, as well as demographic, physiological and psychological aspects (Goel & Göktepe-Hultén, 2019) or the reputation of researchers (Ribas, 2015), all of them useful variables to make comparisons about productivity between groups.…”
