It Depends: Environmental Context and the Effects of Faultlines on Top Management Team Performance
研究了信息断层线（团队成员任务相关属性的分组）对高层管理团队绩效的影响，发现环境动态性、复杂性和丰裕性会调节这种影响。
Informational faultlines, the alignment of team member task-related attributes to form subgroups, are important in explaining team performance. Although informational faultlines may promote specialization and division of labor, they may also increase communication and coordination costs. Integrating work on the categorization-elaboration model, social identity theory, and contingency theory, we posit that facets of a team’s external environment moderate the effects of informational faultlines on performance. Using a sample of 380 top management teams, we examine moderation effects of environmental dynamism, complexity, and munificence. We find that informational faultline strength positively affects firm performance under low environmental dynamism, high complexity, and high munificence, but it negatively affects firm performance under high environmental dynamism, low complexity, and low munificence. We discuss the implications of our findings for theory and practice.
