A Dynamic Process Model for the Design and Assessment of Network Systems

Abstract : Modern warfare has witnessed the proliferation of coalition efforts to contain terrorism. To be successful, these efforts rely upon the effective integration of human and technological agents. Typically, models and analyses of network centric warfare (NCW) focus on technological aspects of a system, eschewing the roles, contributions and decisions made by humans. The Dynamic Model of Situated Cognition (DMSC) emerged as an attempt to represent relationships between technology and humans in a system. The model has been applied in a variety of contexts: individual performance, military command and control, naval operations, human error in military mishaps, and, most recently, to modeling team behavior in complex organizations (Miller & Shattuck, 2004, 2005a, b; Shattuck & Miller, 2004, 2005; Miller, Shobe & Shattuck, 2005). During the 2004 CCRT Symposium, we introduced A Process Model of Situated Cognition in Military Command and Control. We have expanded and refined the model over the last two years and it continues to be well received. In this paper, we review these changes and extend the Dynamic Model of Situated Cognition to serve as an aid for system designers as they consider how individual and team behaviors emerge and interact with complex technology in a system context.
