Diversity in demographic characteristics, abilities and personality traits: Do faultlines affect team functioning?

This study examines the impact of faultlines within teams on cohesion and conflicts. Faultlines concern the attributes of several team members simultaneously and mirror the structure of diversity within a team. The strength of a faultline indicates the level of similarity within potential subgroups and its width the extent of dissimilarity between them. The faultlines addressed in this study are based upon the demographic characteristics, abilities and personality traits of team members. We also address the interaction of team autonomy on the effects of faultlines. Data for this study were collected by means of questionnaires administered to 99 teams of undergraduate students. The results indicate that demographic faultlines directly impair the functioning of a team. Team autonomy conditioned both the relationship between the strength of the ability faultline and team cohesion and the relationship between the depth of the personality faultline and intra-team conflict. In other words, these faultlines are more detrimental to team functioning when team autonomy is high. Ability faultlines seem to emphasize similarities within subgroups, while personality faultlines accentuate dissimilarities between subgroups.
