Training is an integral part of disaster preparedness. Practice in dealing with crises improves our ability to manage emergency situations. As an emergency escalates, more and more agencies get involved. These agencies require training to learn how to manage the crisis and to work together across jurisdictional boundaries. Consequently, training requires participation from many individuals, consumes a great deal of money, and cannot be conducted often. Moreover, in the current crisis management environment, most training is conducted through tabletop and paper-based scenario exercises. In this dissertation, we describe a socio-technical training simulator and research tool for upper level emergency managers. This tool is important because it enables emergency managers to train for crises more efficiently and effectively in a virtual environment. It also serves as a research tool for scientists to study emergency management decision-making and organizational learning.
