Leveraging member expertise to improve knowledge transfer and demonstrability in groups

Group success is dependent on both the knowledge of group members and the extent to which the group can access this knowledge. This research focuses on promoting effective knowledge transfer in group members by facilitating their use of extant knowledge when solving novel problems and examines how this affects subsequent discussion, decision making, and performance. Participants (N = 540) answered a series of estimation items individually or in a group. Sessions were recorded to provide insight into the group interactions. Facilitating knowledge transfer promoted (a) a more effective dialogue in which members were able to share more of their knowledge and discuss member expertise, (b) groups giving greater weight to better member preferences in their decision-making process, and (c) improved group performance relative to both average comparison individuals and to groups operating without this intervention. The effectiveness of promoting knowledge transfer in a group context relative to an individual context is discussed and group superiority is related to the concept of task demonstrability.
