Summary or Abstract : The research plan presented in this study sought to assess and evaluate the decision making procedures, communication activities, and human-computer interactions that facilitate teamwork in 911 dispatch teams. Due to the variability in emergency allocation procedures among 911 dispatch teams across differing contexts, dispatch groups located within two diverse geographical and demographical contexts were evaluated. Data from in situ observations and cognitive task analyses with 911 dispatchers was analyzed according to the principles and implications of three extant theories of teamwork: distributed cognition, transactive memory, and Recognition-Primed Decision (RPD) making. Each theory was evaluated to determine its applications and shortcomings to the characteristics of 911 dispatch group contexts. Additionally, the current research evaluated the application of information technology to support teamwork, team decision making, and the formation of team mental models in 911 dispatch teams within the various contexts of the dispatch teams. The results suggest that geographical and demographical context can affect the nature of teamwork in regards to team decision making procedures, communications, utilization of information technology, and formation of team mental models. The results also revealed fifteen key characteristics or attributes of 911 dispatch teams concerning team decision making, communication, and utilization of information technology. Application of extant theory to the attributes of 911 dispatch teams suggests that distributed cognition theory is more applicable to the study of 911 dispatch teams than transactive memory theory and RPD. Transactive memory was found to be more applicable to the study of 911 dispatch teams than RPD. While all theories were applicable to some of the key attributes of 911 dispatch teams, none of the theories were applicable to all attributes. Additionally, some attributes of 911 dispatch teams were not applicable to any of the theories. Therefore, a new framework, the Rapid Aysnchronous-Synchronous Distributed Decision (RASDD - pronounced "raised") framework, was proposed to account for all key attributes of 911 dispatch teams..
