This document discusses methods for measuring team situation awareness. It describes situation awareness and how it applies to teams. Team situation awareness involves a partially shared mental model between team members that is integrated to anticipate future status. Two methods are described: Coordinated Awareness of Situation by Teams (CAST), which observes team communication during glitches, and Questionnaires for Distributed Assessment of Team Mutual Awareness (QDATMA), which asks individuals to rate their own and others' awareness of tasks, workload, and teamwork. Both methods have advantages and limitations regarding validity, reliability, and ability to capture implicit coordination. More validation studies are needed to evaluate team situation awareness measurement methods.
