What Have We Learned since September 11, 2001? A Network Study of the Boston Marathon Bombings Response

In light of recent disasters, it is evident that more research is needed to understand how organizations can effectively coordinate disaster preparedness, mitigation, response, and recovery efforts. This research assesses the effectiveness of interorganizational coordination and collaboration in response to the Boston Marathon bombings. After reviewing the major changes in federal emergency management policies and frameworks since September 11, 2001, this article applies a social network analysis to compare the disaster response networks embodied in formal disaster preparedness plans with the actual response networks. Data come from content analyses of the Boston Emergency Operations Plan, national and local newspaper articles, after‐action reports, and situation reports. The timely response to the bombings is attributable to long‐term institutionalized planning efforts; multiple platforms established for frequent interorganizational interactions through formal plans, training, and exercises prior to disasters; and an integrated communication system .
