Understanding Diversity

Daan van Knippenberg is Professor of Organizational Behavior at RSM Erasmus University, Erasmus University Rotterdam, The Netherlands. His research interests include work group performance, especially work group diversity and group decision making, leadership, in particular the roles of self and identity, and of emotions, and social identity processes in organizations. In his inaugural address he argues that the effects of work group diversity on group performance should be understood in terms of two processes that have independent and interactive effects: elaboration of task-relevant information and social categorization. He outlines how an integrative model of these processes may explain inconsistent findings in diversity research and provide clear directions for the management of diverse groups. In this respect, he advocates in particular attention for group members’ understanding of work group diversity. Daan van Knippenberg is co-founder of the Erasmus Centre for Leadership Studies, and Associate Editor of Organizational Behavior and Human Decision Processes and of Journal of Organizational Behavior. His research is published in such academic outlets as Journal of Applied Psychology, Organizational Behavior and Human Decision Processes, and Annual Review of Psychology.The key question in diversity research is how differences between group members affect work group process and performance. Over 50 years of research have made clear that diversity can have positive as well as negative effects on performance, but research and practice are still struggling to formulate models that are able to make sense of these diverging effects and that offer clear guidance in how to manage diversity. The Categorization-Elaboration Model (CEM) addresses this issue. The CEM proposes that the effects of work group diversity on group performance should be understood in terms of two processes that have independent and interactive effects: elaboration of task-relevant information and social categorization. Diversity may have positive effects on performance to the extent that it engenders the exchange and integration of task-relevant information (elaboration). At the same time, diversity may be detrimental to performance to the extent that it engenders "us-them" distinctions (social categorization) and intergroup biases – especially because these intergroup biases disrupt information elaboration processes. The CEM also identifies the factors on which the occurrence of elaboration and social categorization processes is contingent, factors that may offer clear angles for the management of diversity

Team Leadership and Team Cultural Diversity:The Moderating Effects of Leader Cultural Background and Leader Team Tenure

By bringing team members with different cultural backgrounds together, teams in international business can benefit from cultural diversity and reach higher levels of performance. Cultural diversity also brings challenges, however, and diversity research has identified the need to consider moderating influences in the diversity–performance relationship. Team leadership should be particularly important in this respect and drawing on a theoretical analysis that puts an understanding of cultural diversity center stage, we propose that factors that reflect leaders’ experience with cultural diversity positively moderate the relationship between cultural diversity and team performance. We identify leader cultural background (local vs. foreign to the host culture) and leader team tenure as such factors. We predict that the influence of team nationality diversity (a form of cultural diversity) on team performance is more positive with a leader who is foreign to the host country than with a local leader, and with a leader with longer team tenure. In addition, we predict that the one moderating influence substitutes for the other, such that the effect of leader cultural background is stronger for leaders with shorter tenure with the team. Results from a survey of N = 66 teams (N = 336 individuals) from a multinational company support these hypotheses and inform our discussion of ways forward in the study of leadership and team diversity.</p

Leader Network Centrality and Team Performance:Team Size as Moderator and Collaboration as Mediator

The social network perspective provides a valuable lens to understand the effectiveness of team leaders. In understanding leadership impact in team networks, an important question concerns the structural influence of leader centrality in advice-giving networks on team performance. Taking the inconsistent evidence for the positive relationship of network centrality and leadership effectiveness as a starting point, we suggest that the positive impact of leader centrality in advice-giving networks is contingent on team needs for leadership to meet communication and coordination challenges, which we argue are larger in larger teams. Developing our analysis, we examine the mediating role of member collaboration in the relationship of leader network centrality and team performance as moderated by team size. Based on a multi-source data set of 542 employees and 71 team leaders, we found that leader centrality in advice-giving networks related positively to team performance in larger teams but negatively in smaller teams. Results supported the mediated moderation model via member collaboration in smaller teams, but not in larger teams

From member creativity to team creativity? Team information elaboration as moderator of the additive and disjunctive models

One of the most fundamental questions in team creativity research is the relationship between individual member creativity and team creativity. The two answers that team creativity research has advanced–teams are more creative when their average member creativity is higher (the additive model) and teams are more creative when their most creative member is more creative (the disjunctive model) are straightforward. Surprising, however, is that neither the additive model nor the disjunctive model is consistently supported, begging the question of what moderates the predictive power of these models. We address this question by integrating individual-to-team creativity models with team process research. We propose that team information elaboration is a key moderating variable, such that average member creativity is more positively related to team creativity with higher information elaboration, and the highest member creativity is more positively related to team creativity with lower information elaboration. A multi-source study of 60 sales teams (483 employees) in a Chinese bakery chain supported these hypotheses. In addition, the study did not support the prediction that the most creative member’s outgoing advice ties (as a conduit for the dissemination of ideas) would further moderate the joint effect of the highest individual creativity and team information elaboration on team creativity

Gender and leadership aspiration: the impact of organizational identification

Purpose Although nowadays more women occupy leadership roles, they still are a minority. Because aspiration is a precursor of advancement, examining conditions fostering female leadership aspiration is important. A neglected perspective is the impact of organizational identification. Identification can be argued to foster leadership aspiration because the essence of leadership is the pursuit of collective interests, and identification motivates such pursuits. The paper aims to discuss these issues. Design/methodology/approach A cross-sectional survey design with an n=400 fulltime employed men and women, working for various organizations was selected. Findings The initial prediction was that identification is more important to women’s leadership aspiration to the extent that gender is associated with communal orientation, because women tend to have stronger communal orientation with associated greater affiliation needs, and organizational identification can be expected to cater to those needs. The communal orientation by organizational identification interactive influence on leadership aspiration was supported. Also, the indirect effect of gender on leadership aspiration via this interactive influence of communal orientation and organizational identification was supported. Research limitations/implications Due to the selected survey approach the data are correlational and as a result no reference to matters of causality can be made. Thus (field) experimental data is needed to confirm these findings. Practical implications Within the paper the discussion focuses on the importance of creating an environment that is more conducive to organizational identification and as such speaks to the communal orientation – being more pronounced among women – to act in favor of the organization by aspiring leadership positions. Originality/value The presented results depict an important step toward understanding how organizational identification and communal orientation interact and how they interact with women’s leadership aspiration

Leadership and Fairness: The State of the Art

Research in leadership effectiveness has paid less to the role of leader fairness than probably it should have. More recently, this has started to change. To capture this development, we review the empirical literature in leadership and fairness to define the field of leadership and fairness, to assess the state of the art, and to identify a research agenda for future efforts in the field. The review shows that leader distributive, procedural, and especially interactional fairness are positively associated with criteria of leadership effectiveness. More scarce and scattered evidence also suggests that fairness considerations help explain the effectiveness of other aspects of leadership, and that leader fairness and other aspects of leadership, or the leadership context, may interact in predicting leadership effectiveness. We conclude that future research should especially focus on interaction effects of leader fairness and other aspects of leadership, and on the processes mediating these effects

Culturally diverse teams may require more central coordination than others

But there is such a thing as too much centralisation, find Christian Tröster, Ajay Mehra and Daan van Knippenber

Work group diversity

Work group diversity, the degree to which there are differences between group members, may affect group process and performance positively as well as negatively. Much is still unclear about the effects of diversity, however. We review the 1997–2005 literature on work group diversity to assess the state of the art and to identify key issues for future research. This review points to the need for more complex conceptualizations of diversity, as well as to the need for more empirical attention to the processes that are assumed to underlie the effects of diversity on group process and performance and to the contingency factors of these processes..
