[Transactive memory in decision-making teams: implications for team effectiveness].

The transactive memory system (TMS) construct is one of the most extended theoretical approaches to understand the role of cognitive processes at group level in the effectiveness of work teams. This study examined the relationships among TMS, performance, satisfaction and functional communication in decision-making teams. 40 four-person teams were asked to suppose they were expert consulting teams advising a fictitious organization on how to solve a problem with their employees. Results showed a mediating effect of TMS on the relationships between functional communication, perceived team performance and satisfaction. Contrary to our expectations, TMSs were not related to performance as evaluated by external raters. These findings suggest the importance of team communication in the formation of TMSs, as well as their implications for the effectiveness of decision-making teams.
