ABSTRACT
The purpose of this chapter is to propose foundations for a systemic theory of situation awareness based on the analysis of interactions between agents (i.e. both human and artefact) in subsystems. This approach may help promote a better understanding of technology-mediated interaction in systems, as well as helping in the formulation of hypotheses and predictions concerning shared situation awareness. It is proposed that agents within a system each hold their own situational awareness which may be very different from (although compatible with) other agents. It is argued that we should not hope for, or indeed want, sharing of this awareness, as different system agents have different purposes. This view marks situational awareness as a dynamic and collaborative process that binds agents together on tasks on a moment-by-moment basis. Implications of this viewpoint for development of a new theory of situational awareness are offered.
