Compositionality of Team Mental Models in Relation to Sharedness and Team Performance

“The better the team mental model, the better the teamwork”, or so is said, in which better model refers to the extent to which the model is shared by the team members. This paper argues that according to circumstances, some components of that model are more relevant with respect to team performance than others. Circumstances change with the dynamics of the environment, the team composition and organization, its members, and the team task. Consequently, a compositional approach to measuring sharedness of team mental models is proposed. A case study illustrates the argument and the approach.
