In my thesis I have investigated the relation between dependency of NGOs on its stakeholders and their autonomy and heteronomy of decision making. Where my research question is: how dependency can influence the decision making in NGOs? Answering my research question I have assumed the hypothesis: more dependent an NGO on its external environment, there is more intervention in the decision making of decision makers. I confirm my hypothesis by conducting an explanatory case study about two known NGOs, Caritas Tirol and Greenpeace Vienna; where collecting the data is by semi structure interviews, and analyzing fifteen interviews from the two NGOs using a deductive qualitative content analysis. Moreover, I find first that dependency (economic, political, and social) can influence the autonomy and the heteronomy of the two NGOs, indifference to the fact that Greenpeace is economically independent; second that the two NGOs are highly dependent on the Media.
