The multiple pathways of high performing groups: the interaction of social networks and group processes
研究考察了内部友谊网络强弱不同的群体如何通过利用外部网络和建设性争论来实现高绩效，发现强关系群体依赖建设性争论，而弱关系群体则需减少外部桥接联系。
Abstract This study examines how both strong and weak relationship groups (groups with numerous, intense internal friendship ties and few, less intense internal friendship ties respectively) achieve high performance when utilizing strategies that capitalize on the strengths and minimizing the weaknesses associated with their internal social structure. We examine the interactions of groups' internal friendship networks with their external network structures (external ties) and internal intragroup conflict (constructive controversy). The results of a study using survey, archival and interview data on 35 groups of MBA students indicated that internal friendship networks interacted with constructive controversy and external networks to determine when groups would achieve superior performance. High performing strong relationship groups engaged in greater constructive controversy than low performing strong relationship groups, while constructive controversy appeared to have minimal effect on the performance of weak relationship groups. High performing weak relationship groups had fewer external bridging ties to other groups when compared to low performing weak relationship groups, while external bridging ties appeared to have minimal effect on the performance of strong relationship groups.
