This research investigates new empirical routes to improve the implementation of sport governance by sports organizations. It asks the question: what determinants influence the decision of sport national governing bodies in Switzerland to implement sport governance? It builds on implementation deficits highlighted by benchmark analysis, an exploratory literature review and a description of the non-profit sector. This paper invites a reflection on the challenges and difficulties related to sport governance standards. The method builds on an exploratory, inductive and qualitative research design. The data comprise interviews with 10 decision makers of national sport federations and the national umbrella federation of sport and Olympic committee analyzed by theme-based coding. The analysis highlights five meta-themes associated with determinants: (1) strategic priority, (2) decision makers’ knowledge on the concept of sport governance, (3) sport governance issues, (4) resources, and (5) personal attributes of decision makers. The results and findings indicate that improving the implementation of sport governance is a multidimensional issue that mainly involves organizational and individual elements, and calls for a tiered approach rather than a “one size-fits all” approach.
