Stronger Than the Sum of Its Parts? The Performance Implications of Peer Control Combinations in Teams
研究同伴规范强度和同伴压力两种控制机制如何互补，通过信任和努力的中介过程影响团队绩效，基于41个自管理医疗团队的多源多波数据。
Integrating theorizing on situational strength and complementarity with control theory, we investigate the mediating processes that transmit peer control combination effects to team performance. We argue that two critical peer control mechanisms—norm strength and peer pressure—complement each other such that their joint impact on team members becomes stronger than the sum of their parts. In a multiple mediator model, we identify effort and trust as two distinct mediating processes that explain the relationship between peer control combinations and team performance. Multisource, multiwave data from 41 self-managing healthcare teams largely support our model. The pattern of mediation was more complex than we anticipated, revealing an indirect effect of peer controls on effort via trust. Together, our findings offer insight into how controls complement each other and the processes through which they do so.
