The existence of effective transactive memory systems in teams has been found to enhance task performance. Methods of developing transactive memory are therefore an important focus of research. This study aimed to explore one such method, the use of a generic team-skills training program to develop transactive memory and subsequent task performance. Sixteen three-member teams were all trained to complete a complex collaborative task, prior to which half the teams (n = 8) completed a team-skills training program. Results confirmed that those teams that had been trained to develop a range of team skills such as problem-solving, interpersonal relationships, goal setting, and role allocation evidenced significantly higher team skill, transactive memory, and performance than those that were not trained in such skills. Results are discussed with reference to the wider transactive memory literature and the mechanisms through which team-skills training could facilitate the more rapid development of transactive memory.
