Transactive memory systems (TMSs) describe the structures and processes that teams use to share information, work together, and accomplish shared goals. First introduced over three decades ago, TMSs have been measured in a variety of ways. This dissertation proposes the use of network analysis in measuring TMS. This is accomplished by describing the creation and administration of a TMS network instrument, evaluating the relation of the proposed network measures and performance, and considering the validity of the proposed network measures. Although the proposed network measures do not appear to be valid in their current form, this study provides motivation for future exploration of using instrumental networks as measures of TMS.
