Massive international response to humanitarian crises such as the South Asian Tsunami in 2004, the Hurricane Katrina in 2005 and the Haiti earthquake in 2010 highlights the importance of humanitarian inter-organizational collaboration networks, especially in information management and exchange. Though, in recent years, humanitarian information management has considerably improved due to significant development in humanitarian information management principles and systems (Van de Walle et al., 2009), humanitarian information sharing continues to challenge the international community (Maiers et al., 2005; Wentz, 2006; Maitland et al., 2009; Bharosa et al., 2010). As I mentioned earlier, in the humanitarian relief field, the number of inter-organizational networks has significantly increased with the rise in number and complexity of humanitarian disasters of the past few decades (Stephenson, 2005; 2006; Ngamassi et al., 2010). The effectiveness of these networks in disaster response is still to be determined. Despite more than a decade old call for better understanding of the effectiveness of inter-organizational networks in the nonprofit context (see O'Toole, 1997; Provan & Milward 1995), to date limited work has been done (Provan et al., 2007).
