Team Situation Awareness (TSA) is one of the intermediate steps in the team decision-making process, widely used to assess performance of human-artifact interaction in many operational domains, such as power plant, aviation, emergency center and so on. However, there is still no clearly understandable, generally accepted, objective ways to measure TSA. Following our previous work on TSA that TSA is modeled as an entity reducible to individual SAs and mutual beliefs, in this study, the authors developed a combination of measures to capture TSA and study various interventions that contribute to formation of TSA. TSA was measured both as a state and a process entity using queries and protocol analysis. Results showed that proposed method is practically useful for TSA measurement.
