Abstract: Most information systems (IS) research into emergency management (EM) consists of case studies of prior disasters, social behavior research, and planning or preparedness research. This study fills a gap in EM and IS research as it aims to better understand the nature of coordination during crisis response; investigate the functions and capabilities of existing coordination systems; and identify the desired functions to manage multi-agency coordination response. Grounded theory is the methodology adopted for this study. Firsthand interview and observational data will be collected from agency command centers, ride-outs with police, fire, and emergency medical services (EMS) agencies, and from multi-agency training exercises. This study is expected to make a theoretical contribution to crisis response system design as it will develop a theory to better understand the information requirements for context-aware multi-agency real-time coordination responses to crises.
