Team Situation Awareness (TSA) is a critical contributing factor in enhancing reliability of team performance. How to effectively incorporate between human teams and artifacts, how to achieve mutual understanding, is the major topic in this paper. Based on our previous study on TSA, an argument will be presented that recognition, SA inferring, and mutual responsiveness are the prerequisite abilities to engage in cooperative activity. We also develop the principle to assess appropriateness of TSA from two aspects: the soundness and completeness of mutual belief. Simulation results will be given to indicate that team uses the information from external environment to establish effective TSA based on internal knowledge.
