Demographic antecedents and performance consequences of structural holes in work teams

This paper addresses two important questions concerning social fragmentation in work teams. First, from where do disconnections between team members, measured in terms of the proportion of structural holes within the work team, derive? Second, what are the consequences for team performance of having more or less structural holes between team members? In answering the first question, the research investigated whether demographic diversity in teams played a role in predicting the proportion of structural holes in team friendship networks. For 19 teams at a wood products company, there were no effects of ethnic and gender diversity on structural hole proportions. However, age diversity significantly reduced the extent of structural ‘holeyness.’ In investigating the second question, two countervailing tendencies were considered. In the absence of structural holes, teams are likely to be at low risk for new ideas. But fragmented teams in which team members are separated by many structural holes are likely to have difficulty coordinating. The researchers demonstrated a curvilinear effect: a moderate level of structural diversity in teams was positively associated with team performance. Thus, the research suggested that it is structural diversity (measured in terms of the proportion of structural holes) rather than demographic diversity that matters in the prediction of team performance.

The social identity and social networks of ethnic minority groups in organizations: a crucial test of distinctiveness theory

Distinctiveness theory posits that patterns of social identity and friendship are based on numeric rarity within specific contexts. In ethnically diverse organizations, the theory predicts that members of the smaller ethnic group (relative to members of the larger ethnic group) will: (a) tend to identify and form friendships within their own ethnic group, and (b) lack access to well‐connected individuals in the network of friendship relations. Prior tests have supported these predictions, but they have been unable to rule out the possibility that it was chronic differences in social status and numeric representation in society at large (rather than numeric distinctiveness within specific contexts) that explained the observed patterns of social identity and friendship. In this field‐based study, we examined an organization whose social composition effectively controlled for these confounds. We found that members of the smaller ethnic group tended to identify and form friendships within group, as predicted by distinctiveness theory. However, in contrast to previous work, we found that members of the smaller ethnic group were equally well connected to the center of the friendship network as were the members of the larger ethnic group.

Diversity and team outcomes: the moderating effects of outcome interdependence and group longevity and the mediating effect of reflexivity

Reflexivity—the extent to which teams reflect upon and modify their functioning—has been identified as a possible key factor in the effectiveness of work teams. We examined the extent to which team composition affected team process (i.e., reflexivity) and in turn team outcomes (i.e., satisfaction, commitment, and performance). The results of diversity research thus far have been inconclusive in terms of positive or negative effects of team composition on team process and outcomes. In the current research, group longevity and outcome interdependence were expected to moderate the relationship between diversity on the one hand and reflexivity and team outcomes on the other hand. Reflexivity was expected to mediate these interaction effects. The current field study was conducted among 54 work teams from 13 different organizations. As predicted, few main effects were found. Instead, analyses showed interaction effects of diversity and outcome interdependence on the measures of reflexivity, satisfaction, and performance. As predicted, interaction effects were also found for diversity and group longevity on the measures of reflexivity, satisfaction, and performance. Three‐way interactions were found for satisfaction and commitment. Also, reflexivity was shown to mediate these relationships, indicating that the moderating effects of outcome interdependence and group longevity on the relation between diversity and team outcomes are due to the effects on process.

Me and us: differential relationships among goal‐setting training,efficacy and effectiveness at the individual and team level

Efficacy‐effectiveness relationships were examined for individual nurses and nursing teams who were either trained or untrained in goal‐setting. At the individual level, positive direct relationships were demonstrated between self‐efficacy and effectiveness, between training and subsequent self‐efficacy, and between training and effectiveness. Initial self‐efficacy also moderated the training‐effectiveness relationship. Nurses low in initial self‐efficacy realized greater effectiveness gains from the training than did nurses high in initial self‐efficacy. At the team level, group efficacy was related to effectiveness, and training was related to subsequent group efficacy, but training was not related to effectiveness, and there were no moderation effects for initial group efficacy. Collective cognition and behavioral plasticity are potential explanations for different effects at the individual and team level and avenues for theory development and future research.

Good acting requires a good cast: A meso‐level model of deep acting in work teams

This study proposes and tests a meso‐level model of deep acting in work teams that draws on emotional contagion theory to explain how shared means of complying with display rules can arise in work teams. We argue that the presence of influential deep actors can lead to greater convergence (lower dispersion) on individual deep acting in the team. That is, team members behave more similarly. When a team has greater convergence, deep acting by individual members should be related to lower emotional exhaustion and higher job satisfaction and in‐role performance. In a sample of mature work teams, these hypotheses received general support. Our findings suggested that team‐level deep acting effects can foster benefits for team members (lower emotional exhaustion and higher satisfaction) and organizations (higher job performance).

Teams as boundaries: How intra‐team and inter‐team brokerage influence network changes in knowledge‐seeking networks

What role does an ego's brokerage location—within a team (intra‐team) or outside the team (inter‐team)—play in the evolution of an instrumental knowledge‐seeking network in terms of both proximal (i.e., within the team) and distal (i.e., outside the team) tie formation and tie decay? We address this question by drawing on literature about social networks, brokerage, and teams. We use temporally separated data from 302 students embedded in 97 teams to test our hypotheses about the impacts of intra‐team and inter‐team brokerage on proximal and distal network evolution, specifically on four network changes in knowledge‐seeking networks: proximal tie formation, proximal tie decay, distal tie formation, and distal tie decay. We find that these four changes depend on individual network brokerage location even after controlling for personality and task characteristics. Specifically, inter‐team brokers change their networks both within and outside their teams, whereas intra‐team brokers curtail their network changes. We argue that these opposite effects occur because inter‐team brokers have greater autonomy than intra‐team brokers. This study adds to the ongoing dialog about network evolution in social network literature and to the conversations about brokerage and its location in the context of team‐based work.     

The emergence of team helping norms: Foundations within members' attributes and behavior

This research examined the antecedents of organizational citizenship behavior helping norms in teams, specifically with regard to how members' personality, values, beliefs, and helping behavior predict the emergence of helping norms in newly formed project teams. We drew from theory on emergent phenomena and team composition research to propose and test a compilation model of how helping norms are influenced by having at least one member with particularly low (minimum) or high (maximum) levels of attributes that may influence helping‐norm development (i.e., conscientiousness, agreeableness, other‐oriented values, personal helping beliefs). We further examined the extent to which members' helping behaviors, as rated by peers, predicted helping norms and whether these behaviors mediated the relationship between individual attributes and helping norms. The results of a longitudinal study of 47 student project teams revealed that teams' minimums on agreeableness, other‐oriented values, and personal helping beliefs had direct relationships with helping‐norm emergence, and the effects of agreeableness were mediated through mean helping behavior. By contrast, teams' maximums on these attributes showed no relationships with helping norms, and only a team maximum on agreeableness was associated with teams' mean helping behavior.

Missing persons in the study of groups

This research examined relationships between team‐level variables with various patterns of individual non‐response. In the first analysis, professional basketball teams (n = 389) were used to study the relationship between team cooperation and team performance. In the second analysis, the same teams were used to study the relationship between team experience and team performance. In the third analysis, professional baseball teams (n = 1984) were used to study the relationship between team experience and team performance. Individuals were deleted from the complete data sets to simulate three different types of non‐response that might be encountered in organizational group or team research. In all three analyses, team‐level relationships were attenuated as individual members were deleted randomly. Team‐level relationships were also generally reduced as individuals were deleted as a function of their level of participation with the team. The overall amount of variance explained, however, showed a pronounced curvilinear effect. Namely, in all three analyses, the variance explained in team performance peaked when 30–40 per cent of the low‐participation members were deleted. Finally, in the first analysis, relationships were also attenuated as the least cooperative members were deleted from the data set. The results demonstrate the need for researchers to understand the diverse effects of various types of non‐response in team and group research. Copyright © 2005 John Wiley & Sons, Ltd.     

Adjusting to new work teams: Testing work experience as a multidimensional resource for newcomers

The successful performance adjustment of team newcomers is an increasingly important consideration given the prevalence of job‐changing and the uncertainty associated with starting work in a new team setting. Consequently, using sensemaking and uncertainty reduction theories as a conceptual basis, the present study tested work experience as a potential resource for newcomer performance adjustment in teams. Specifically, we tested work experience as a multidimensional predictor of both initial newcomer performance and the rate of performance change after team entry. We tested hypotheses using longitudinal newcomer performance data in the context of professional basketball teams. Although the traditional quantitative indicators of the length and amount of work experience were not meaningfully associated with newcomer performance adjustment, their interaction was. In addition, the qualitative indicator of newcomers' past transition experience revealed a significant, positive association with the rate of newcomer performance improvement following team entry. These results suggest that work experience is a meaningful facilitator of newcomer adjustment in teams and emphasize the dual consideration of both quantitative and qualitative work experiences. The theoretical and practical implications of these findings are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Scaling the quality of teammates' mental models: equifinality and normative comparisons

We tested the impact of teammates' team and task mental model sharedness on team processes and performance using 70 undergraduate teams that completed a series of missions on a PC‐based flight simulator. Moreover, we considered how the quality of mental models might moderate such relationships. Team processes were found to partially mediate the relationship between task mental model sharedness and team performance. Although team mental model sharedness failed to exhibit a significant linear relationship with team processes or performance, it did evidence a multiplicative relationship as moderated by the quality of those models. Team processes and performance were better among teams sharing higher‐quality team mental models than among teams evidencing less sharedness or who had lower‐quality models. Again, team processes partially mediated these relationships. Results are discussed in terms of the equifinality of mental model quality and applications to various team environments.

Redesigning computer call center work: a longitudinal field experiment

Computer technology call centers provide technical assistance to customers via the telephone to solve computer hardware and software problems. The simultaneous demands for technical and customer service skills often place strain on call center employees, frequently producing poor job attitudes. We utilized a field experiment (N = 149) with a randomly assigned pretest–posttest and control group design to compare three interventions' effectiveness on employee job attitudes in a computer technology call center: Intervention 1 focused on aligning organizational structures; Intervention 2 focused on increasing employee involvement in work processes (high‐involvement); and Intervention 3 implemented autonomous work teams. We found that high‐involvement work processes produced the most potent effects on job satisfaction and organizational commitment attitudes, as well as on performance (i.e., improved customer satisfaction scores, increased closed problems, reduced problems escalated, and fewer repeat calls). Further, we found that group work preference moderated the results between the group‐oriented interventions and employees' job satisfaction. Under high involvement and in autonomous work teams, high preferences for group work resulted in greater job satisfaction than when employees had lower preferences for group work. However, preferences for group work were not associated with increased organizational commitment in either intervention. Copyright © 2004 John Wiley & Sons, Ltd.

Putting first things first: Outcome and process focus in knowledge work teams

This paper presents a new perspective on the management of outcomes and processes in a knowledge team's work. Knowledge teams frequently face complex, open‐ended tasks for which the a priori specification of goals and work processes is not possible. Such teams must define these work elements themselves; emphasizing one over the other can lead a team to become either outcome‐or process‐focused, with implications for the level at which they identify their activities and the flexibility with which they conduct work. A survey study of student teams and a field study of organizational teams test the effects of outcome versus process focus on performance. Consistent with prior findings, the first study demonstrates that outcome focus is positively related to performance on complex, open‐ended tasks and that team members' level of action identification mediates the effects of outcome and process focus on performance. Action research conducted as part of the second study demonstrates the importance of early events in a team's life cycle and the challenge for managers who hope to influence their teams to have a greater degree of focus on outcomes over process.

Individualism–collectivism and team member performance: Another look

This study revisits the commonplace research conclusion that greater team member collectivism, as opposed to individualism, is associated with higher levels of individual‐level performance in teams. Whereas this conclusion is based on the assumption that work in teams consists exclusively of tasks that are shared, typical teamwork also includes tasks that are individualized. Results of a laboratory study of 206 participants performing a mix of individualized and shared tasks in four‐person teams indicate that heterogeneous combinations of individualism and collectivism are associated with higher levels of team member performance, measured as quantity of output, when loose structural interdependence enables individual differences in individualism–collectivism to exert meaningful effects. These results support the modified conclusion that a combination of individualism and collectivism is associated with higher levels of member performance in teams under typical work conditions; that is, conditions in which the tasks of individual members are both individualized and shared.

Team job‐related anxiety and creativity: Investigating team‐level and cross‐level moderated curvilinear relationships

Researchers have examined the effects of individual job‐related anxiety on employee attitudes and behaviors but have yet to examine whether team job‐related anxiety would have similar or different effects. Building on prior research on negative group affective tone and creativity, we propose that team job‐related anxiety has an inverted U‐shaped curvilinear relationship with both team and individual creativity. Furthermore, we posit that team cooperativeness moderates those curvilinear relationships. Using a two‐wave research design and matched employee‐supervisor data from 290 employees nested in 65 teams, we found support for the proposed inverted U‐shaped relationships. Moreover, the intermediate level of team job‐related anxiety was associated with higher individual creativity in teams with higher cooperativeness. We conclude the study with a discussion of the theoretical and practical implications of our findings.     

Energy's role in the extraversion (dis)advantage: How energy ties and task conflict help clarify the relationship between extraversion and proactive performance

While academic and practitioner literatures have proposed that extraverts are at an advantage in team‐based work, it remains unclear exactly what that advantage might be, how extraverts attain such an advantage, and under which conditions. Theory highlighting the importance of energy in the coordination of team efforts helps to answer these questions. We propose that extraverted individuals are able to develop more energizing relationships with their teammates and as a result are seen as proactively contributing to their team. However, problems in coordination (i.e., team task conflict) can reverse this extraversion advantage. We studied 27 project‐based teams at their formation, peak performance, and after disbandment. Results suggest that when team task conflict is low, extraverts energize their teammates and are viewed by others as proactively contributing to the team. However, when team task conflict is high, extraverts develop energizing relationships with fewer of their teammates and are not viewed as proactively contributing to the team. Our findings regarding energizing relationships and team task conflict clarify why extraversion is related to proactive performance and in what way, how, and when extraverts may be at a (dis)advantage in team‐based work.

Should we be “challenging” employees?: A critical review and meta‐analysis of the challenge‐hindrance model of stress

The challenge‐hindrance model of stress proposes that stressors can be divided into two distinct groups: those that challenge employees and those that hinder employees. This critical review seeks to explain the history of the model and its basic tenets, while succinctly summarizing the findings of existing studies based on the model. A thorough search of the stress literature uncovered 32 studies that specifically examined the relationship between challenge and hindrance stressors and important personal/organizational variables. Results were reviewed and analyzed, specifically by describing past meta‐analyses on the model, looking at the overall pattern of results from primary studies, and meta‐analyzing the relationships presented in those papers. This synthesis suggests that although there are some differential relationships of challenge and hindrance stressors with organizational variables (e.g., performance and engagement), the relationships to other key variables, such as counterproductive work behaviors, psychological strains, and physical health, are consistently negative for both challenge and hindrance stressors. Thus, we propose that stress research move away from the current challenge‐hindrance model in favor of other established models and/or a more appraisal‐based approach.     

Self-directed workteams and safety: a winning combination?

The organization of work into self-directed work teams (SDWT) has considerably changed the power structure within companies. In addition to carrying out the work, SDWT members make decisions that are traditionally the jurisdiction of first line supervisors. This exploratory research examines the impact of this type of group empowerment on the management of health and safety in twelve factories in Quebec. As expected, the management of health and safety is greatly modified when self-directed work teams are implemented. These teams play a major role in the planning, implementation and monitoring of corrective measures on the shop floor. Staff and management provide support and advice to the work teams, but make fewer and fewer decisions themselves. Peer pressure, when perceived as legitimate, is likely to positively influence the safety attitudes and behaviours of team members. Furthermore, the safety performance of these organizations is actually better than average. However, our respondents were concerned about the growing lack of health and safety leadership displayed by some managers. They worry about the definition of roles, integration of occupational health and safety (OHS) concerns and adoption of OHS measures by less mature work teams. Peer pressure is not always seen as legitimate, thereby causing tension. Finally, our respondents were concerned about the stress and health difficulties that may be related to group decision-making and added responsibilities.     

On the relationship between intragroup conflict and social capital in teams: A longitudinal investigation in Taiwan

In response to the prevalent deployment of teams in organizations, there is a need to jointly consider conflict and social capital within the teams to offer novel ways to understand group process. This study proposes that the association between intragroup conflict and group social capital may be dynamic and reciprocal. Specifically, this study investigates longitudinally how intragroup conflict influences group social capital within cross‐functional teams and recognizes whether the teams with high group social capital can further produce intragroup conflict. The two‐year longitudinal study sampled 527 individuals in 90 teams across two time periods. This study finds that when teams are formed (Time 1), task conflict relates positively to structural social capital, and relationship conflict relates negatively to cognitive social capital. There is an inverted U‐type relationship between task conflict at Time 1 and social capital at Time 2. Established teams (Time 2) with higher levels of social capital experience higher levels of task conflict and lower levels of relationship conflict than teams with lower levels of social capital.

Long work hours: a social identity perspective on meta‐analysis data

The current study utilizes social identity theory to investigate employees' work hours. Specifically, we use meta‐analysis to examine the relationships between hours worked and indicators of organizational identity (e.g., organizational support and tenure), occupational identity (e.g., human capital investments and work centrality), and family identity (e.g., family responsibilities and family satisfaction). The meta‐analysis also allowed us to explore other important correlates of hours worked (e.g., situational demands, job performance, mental health, and physical health), moderating variables (e.g., age, gender, and job complexity), and curvilinear relationships of work hours to social identity indicators. Overall, we found that occupational factors and situational demands had the strongest relationships with hours worked, hours worked were negatively associated with measures of employee well‐being, gender had several significant moderating effects, and there were curvilinear relationships between hours worked and well‐being and work–family conflict variables. The article concludes with directions for future theoretical and empirical research. Copyright © 2008 John Wiley & Sons, Ltd.
