SummaryBecause research on team mental models is still in its formative stages, there is a need for continued conceptual development of the construct and direct empirical support linking team mental models to team outcomes. Researchers in other ®elds have developed concepts that are distinct from, but clearly related to team mental models, including information sharing, transactive memory, group learning, and cognitive consensus. Although these research streams currently exist in parallel with little cross-fertilization, there is much to be gained from integration across disciplinary boundaries. Therefore, the purpose of this paper is to enrich the theoretical understanding of team mental models and to broaden the empirical research base by adopting a cross-disciplinary focus and incorporating related team knowledge domains from other literatures. Based on a synthesis of various literatures, we develop a framework that delineates the relationships among team knowledge constructs.
