In this paper, we describe a team cognitive task analysis (CTA) conducted for the purpose of guiding the development of training and training systems for large, distributed tactical teams. This effort is based on the premise that challenges associated with working in a large, distributed tactical team differ from those associated with working in less complex (e.g., smaller or co-located) teams. This difference means that team training paradigms developed in recent years for the latter type of team may not adequately support team integration expertise in the more complex type of team. Thus, our goals include identifying (1) challenges to team coordination in large, distributed tactical teams; (2) knowledge and skills used to achieve coordination in the face of those challenges; and (3) training guidelines and approaches that support the acquisition of team coordination knowledge and skills. To these ends, we performed a training requirements analysis of the naval air wing domain and are performing a CTA to assess the knowledge and skills used by expert versus novice aviators in support of team coordination. The CTA and its implications for training design are the focus of this paper.
