Why Differences Make a Difference: A Field Study of Diversity, Conflict, and Performance in Workgroups

A multimethod field study of 92 workgroups explored the influence of three types of workgroup diversity (social category diversity, value diversity, and informational diversity) and two moderators (task type and task interdependence) on workgroup outcomes. Informational diversity positively influenced group performance, mediated by task conflict. Value and social category diversity, task complexity, and task interdependence all moderated this effect. Social category diversity positively influenced group member morale. Value diversity decreased satisfaction, intent to remain, and commitment to the group; relationship conflict mediated the effects of value diversity. We discuss the implications of these results for group leaders, managers, and organizations wishing to create and manage a diverse workforce successfully.

Assessing the Relationship between Industry Characteristics and Organizational Culture: How Different can You Be?

This study investigated the relationship between two industry characteristics, technology and growth, and organizational culture. We examined this relationship by comparing the cultures of organizations within and across industries. Using 15 firms representing four industries in the service sector, we found that stable organizational culture dimensions existed and varied more across industries than within them. Specific cultural values were associated with levels of industry technology and growth. One implication of this finding is that the use of organizational culture as a competitive advantage may be more constrained than researchers and practitioners have suggested.

INTRAGROUP CONFLICT IN ORGANIZATIONS: A CONTINGENCY PERSPECTIVE ON THE CONFLICT-OUTCOME RELATIONSHIP

Abstract In this paper, we review recent empirical work on interpersonal conflict in organizations and, by incorporating past theory and multiple disciplinary views, develop a comprehensive model of the effects of intragroup conflict in organizations from a contingency perspective. We consider: (1) the type of conflicts that exist; (2) the organizational outcome that is predicted or desired; (3) the temporal aspect of group life and conflict; and (4) the circumstances under which conflict occurs and the processes used to manage it that moderate the conflict-outcome relationship. We highlight the final aspect, the moderating factors, by presenting a conflict-outcome moderated (COM) model that delineates types of moderators which influence the conflict-outcome relationship: amplifiers (those variables that amplify the conflict-outcome relationship, strengthening both the positive and negative effects), suppressors (those variables that weaken both the positive and negative effects on outcomes), ameliorators (those variables that decrease negative effects and increase positive effects), and exacerbators (those variables that increase negative effects of conflict and decrease positive effects). We ultimately present a model of constructive intragroup conflict in organizations delineating the contingencies upon which group success, as it relates to conflict, is dependent.

Interpersonal relationships and task performance: An examination of mediation processes in friendship and acquaintance groups.

This study used multiple methods to examine group processes (information sharing, morale building, planning, critical evaluation, commitment, monitoring, and cooperation) that mediate the effect of relationship level on group performance. The study uses a 2 by 2 experimental design, crossing relationship (friendship vs. acquaintance) as a between-subjects variable and task type (decision making vs. motor) as a within-subject variable. Fifty-three 3-person groups participated in the study, and data from 4 types of measurement were used to analyze the mediating processes between relationship level and task performance. Friendship groups performed significantly better than acquaintance groups on both decision-making and motor tasks because of a greater degree of group commitment and cooperation. Critical evaluation and task monitoring also significantly increased decision-making performance, whereas positive communication mediated the relationship between friendship and motor task performance.

The Paradox of Intragroup Conflict: A Meta-Analysis.

Since the meta-analysis by De Dreu and Weingart (2003b) on the effects of intragroup conflict on group outcomes, more than 80 new empirical studies of conflict have been conducted, often investigating more complex, moderated relationships between conflict and group outcomes, as well as new types of intragroup conflict, such as process conflict. To explore the trends in this new body of literature, we conducted a meta-analysis of 116 empirical studies of intragroup conflict (n = 8,880 groups) and its relationship with group outcomes. To address the heterogeneity across the studies included in the meta-analysis, we also investigated a number of moderating variables. Stable negative relationships were found between relationship and process conflict and group outcomes. In contrast to the results of De Dreu and Weingart, we did not find a strong and negative association between task conflict and group performance. Analyses of main effects as well as moderator analyses revealed a more complex picture. Task conflict and group performance were more positively related among studies where the association between task and relationship conflict was relatively weak, in studies conducted among top management teams rather than non-top management teams, and in studies where performance was measured in terms of financial performance or decision quality rather than overall performance.

Cracks in Diversity Research: The Effects of Diversity Faultlines on Conflict and Performance

In this quasi-field study, we investigate the effects of diversity faultlines on the conflict experience, performance, and morale of 79 groups. This is one of the first studies to operationalize the construct of diversity-related faultlines (Lau and Murnighan 1998). One of the most important contributions of this research is that faultlines incorporate multiple characteristics of group members simultaneously rather than assessing just one demographic characteristic at a time as most past diversity research has done. We develop a measure to capture the complexity of the faultline construct and to examine the effects of various group diversity faultline profiles on group outcomes. Linear results with a limited range of data show that faultlines are negatively related to conflict and positively related to morale and performance. Supplemental analyses that take into account the unique characteristics of our dataset indicate curvilinear relationships between diversity faultlines and relationship conflict, process conflict, group morale, and group performance. Groups with either virtually no faultlines (very diverse members) or strong faultlines (split into 2 fairly homogeneous subgroups) had higher levels of conflict and lower levels of morale and performance than groups with medium faultlines. The results suggest a more complex relationship between diversity and group process and outcome variables than typically described in diversity research. A detailed discussion of the faultline measure we developed and the methodological issues associated with measuring and interpreting faultlines are reported.

Do friends perform better than acquaintances? the interaction of friendship, conflict, and task

This article examines the influence of friendships among group members, intragroup conflict, and task on group performance. Previous research has found that friendships among group members (operationalized as group affinity, comraderie, or cohesion) has both positive and negative effects on performance. The effect of friendship on performance is contingent on many factors. The focus of this article is on the different types of conflict experienced by groups and on the type of task that the group is performing. The results indicate different interaction patterns and degrees of conflict (emotional, task content, and administrative conflict) in friend (strong relationship) groups and acquaintance (weak relationship) groups. Overall, the findings suggest that friend groups perform significantly better than acquaintance groups on both decision-making and motor tasks. Process data from transcripts of group discussions also suggest several mediating factors that may account for these performance differences.

Conflict transformation: a longitudinal investigation of the relationships between different types of intragroup conflict and the moderating role of conflict resolution

In this longitudinal study, the authors examine the relationships between task, relationship, and process conflict over time. They also look at the role of conflict resolution in determining whether certain forms of intragroup conflict are related to the appearance of other forms of conflict over time. Their findings indicate a negative and long-lasting impact of process conflict occurring early in the teams interaction. Specifically, they find that process conflict, but not task or relationship conflict, occurring early in a teams interaction leads to higher levels of all other conflict types for the remaining interactions of the team. In addition, the authors find that the effect of process conflict on the other types of conflict over time may be limited when members are able to resolve their process conflicts at the start of their time together.

Using triangulation to validate themes in qualitative studies

Purpose – The purpose of this paper is to provide instructional guidance on how to increase validity and reduce subjectivity in qualitative studies, such as grounded theory. The paper also demonstrates how different techniques can help management research by including informants/managers in a time efficient way.Design/methodology/approach – This paper describes how three complementary triangulation methods can be used for validation and exploration of concepts and themes in qualitative studies. Tree graphs, concept mapping, and member checking are applied in a managerial case study, complementing a conventional grounded theory approach.Findings – The paper suggests that naturalistic inquiries, such as grounded theory and thematic analysis, can use mixed methods and multiple sources and coders in order to offset biases and to validate and sort findings. The case study presents three different perspectives on how an organization comprehends diversity as a strategic issue.Originality/value – The paper sugges...

The effects of conflict asymmetry on work group and individual outcomes

We examine the consequences of an often ignored aspect of work group conflict—asymmetric conflict perceptions—for the effectiveness of individuals and groups. Tests of our multilevel hypotheses using data on 51 work groups showed that group conflict asymmetry (the degree to which members differ in perceptions of the level of conflict in their group) decreased performance and creativity in groups. In addition, individual conflict asymmetry (a member perceiving more or less conflict than other group members) explained reported performance and satisfaction with a group. Social processes and a positive group atmosphere mediated this effect.
