Little consensus has emerged about how organizational performance should be defined and measured. Most studies have used traditional approaches to give their own perspective about organizational performance and effectiveness, but none have recently tried to encompass these different views into one unified model. In the present paper, Chelladurai's systems view of organizations is used to integrate the dimensions of organizational performance highlighted by previous studies on non-profit sport organizations. These organizational performance dimensions are highlighted and categorized into macro-dimensions (e.g., financial resources acquisition, size, internal atmosphere, organizational operating, financial independence, achieving elite sport success and mass sport participation). Relationships between these macro-dimensions are analyzed. A multidimensional framework is developed which gives an overview of which dimensions constitute organizational performance in non-profit sport organizations and of how to measure them. Further research directions and management implications are discussed.Keywords: literature review, non-profit sport organizations, organizational performance, systems view model, unified model, sport management, performance measurement Running head: NON-PROFIT SPORT ORGANIZATIONS PERFORMANCE 3The construct of organizational performance assesses an organization's performance by evaluating the input (e.g., available resources), throughput (e.g., processing of the input) and output (e.g., goals achieved) of the organization. However, little consensus has emerged, either theoretically or empirically, to what constitutes organizational performance and how to measure it (Sowa, Selden & Sandfort, 2004). The increasing amount of literature and research on this topic is characterized by varying theoretical perspectives and research objectives, which make accumulation and integration very hard (Herman & Renz, 1999). Nonetheless, the option to move away from defining (and measuring) performance (effectiveness and efficiency) is not a viable one (Venkatraman & Ramanujam, 1986). Performance is of theoretical, empirical and practical significance. Even in non-profit organizations (NPOs), questions of performance have become increasingly important in the world of practice, as government and philanthropic funders, clients, and the public exert increased pressure on NPOs to demonstrate their impact on complex social problems (Sowa, Selden & Sandfort, 2004). The apportioned amount of subsidy is usually based on some predetermined criteria related to the characteristics, performance and effectiveness of organizations (Papadimitriou, 2007;Schulz, 2005). As a result, rational criteria and conditions for investments, subsidies and their priorities need to be established (Lim et al., 1994). Consequently, the application of organizational performance criteria to NPOs management becomes increasingly important.To our knowledge, no recent study has fully attempted to synthesize the literature on the organizational pe...
