Abstract: Group diversity research has gained much progress in the past two decades, but still little has been known about how diversity affects group process and its effectiveness. This paper reviewed recent literature on group diversity, and proposed a series of theoretical development and empirical evidence based on group faultlines theory, with particular emphasis on the interpretation of best practice and contingency factors. Finally, this study discussed some key issues for future diversity research as well as its managerial implications.

Key words: diversity, group faultlines, integrative model, contingency factors
