Leading teams over time through space: Computational experiments on leadership network archetypes

A key function of team leadership is building and sustaining shared mental models. Topological approaches to leadership identify structural patterns, such as decentralized and shared leadership that empower members to collectively lead themselves toward important goals, but an open question is the particular form of leadership that best promotes team mental models. We explored 8 leadership archetypes using a computational model fit on data from a unique sample of NASA analog space crews. Data from 4, 4-member crews living and working together for 45-days were used to parameterize the model which then accurately predicted mental models for the next set of 4-member crews. The validated model was used to conduct virtual experiments exploring the effects of leadership structures on mental models. We found shared leadership has the largest effect on shared mental models, followed by hierarchical and coordinated leadership. These findings extend shared leadership theory leveraging computational methods to examine leadership archetypes and suggest propositions about how they shape team functioning over time.     

Measuring Sharedness of Team-Related Knowledge: Design and Validation of a Shared Mental Model Instrument

Many researchers have explored how people share and construct similar mental models in teams. They have claimed that successful team performance depends on a shared mental model of team members about task, team, equipment and situation. Most of the literature has illustrated simplified relationships between a team's mental model and their performance without a valid instrument addressing the confined and relevant constructs of a shared mental model. This paper describes the instrument development steps and the conceptual framework for factors associated with shared mental models. After development and refinement, the instrument was finalized for use to measure team-related knowledge. The final instrument consists of 42 items that are linked to the five emergent factors of shared mental models including general task and team knowledge, general task and communication skills, attitude toward teammates and task, team dynamics and interactions, and team resources and working environment.     

The servant leadership advantage: When perceiving low differentiation in leader-member relationship quality influences team cohesion,team task performance and service OCB

How does servant leaders' unique ability to place each follower's needs above their own influence relationships between followers and impact their collective performance? In a study that integrates principles of servant leadership with the social comparison theoretical framework, we tested a group-level model to examine how servant leadership induces low perceived differentiation in leader-member relationship quality (perceived LMX differentiation) within a group, which strengthens team cohesion and in turn positively influences team task performance and service-oriented organizational citizenship behaviors (service OCB). Our sample comprised 229 employees nested in 67 work teams. Structural equation modeling results indicate that servant leadership significantly predicts low perceived LMX differentiation; perceived LMX differentiation is strongly related to team cohesion such that the lower the perceived differentiation, the stronger the team's cohesiveness. And, team cohesion is also strongly related to both the team's task performance and service OCB. Perceived LMX differentiation and team cohesion mediate the effect of servant leadership on both team task performance and service OCB.     

A team level investigation of the relationship between Leader–Member Exchange (LMX) differentiation,and commitment and performance

Although the differential treatment of team members by their leader is at the heart of Leader–Member Exchange (LMX) theory, empirical studies exploring the role of within-team LMX differentiation in relation to team outcomes are still relatively scarce. This study among 269 Dutch secondary school teachers from 33 different teams tested the hypotheses that the relationship between LMX differentiation and team commitment, and team performance is moderated by LMX-quality median. Moreover, we hypothesized that team members' perceived dissimilarity regarding work values and orientations would be positively related to within-team LMX differentiation. Teachers completed questionnaires on LMX-quality, dissimilarity, and team commitment, whereas team performance was rated by school principals. Results indeed showed that LMX differentiation is positively related to both outcome variables in teams with a low LMX-quality median only. As expected, more perceived dissimilarity between team members was related to more within-team variability in LMX-scores. These results contribute to knowledge on hypothetical antecedents and consequences of LMX differentiation at the team level.     

Emergence of shared leadership networks in teams: An adaptive process perspective

Adaptive leadership theory suggests that shared leadership networks grow in a complex manner. We propose that leadership decentralization (the dispersion of leadership), leadership density (the total amount of leadership), and situationally-aligned leadership (SAL: leadership transitions to those who fit situation requirements) are distinct aspects of a shared leadership network and should be examined together to capture the development of shared leadership process. Through a study of 450 participants in 90 teams, we find that each of these three aspects of shared leadership plays a different role during shared leadership network emergence. Specifically, transactive memory systems (TMS) contribute to decentralized leadership structures, which in turn precipitate more dense leadership networks. We also find that TMS contributes to the most situationally aligned team member engaging in leadership. Both leadership density and SAL predict team performance. We discuss the theoretical and practical implications of these results.     

Shared leadership performance relationship trajectories as a function of team interventions and members' collective personalities

We used longitudinal data from 205 members of 53 student teams who competed in a complex business simulation over 10 weeks to test: (1) whether shared leadership and performance were related reciprocally over time; (2) the relative magnitude of those relationships; and (3) whether a shared leadership intervention changes those relationships. We also considered the influence of team members' mean level personality to account for compositional effects. As anticipated, shared leadership and performance were related positively and reciprocally over time. Moreover, the shared leadership to performance relationship grew stronger and positive whereas the performance to shared leadership relationship remained fairly consistent over time. As expected, the intervention positively related to the trajectory of shared leadership. Finally, we did not find evidence for the hypothesized relationships of personality on shared leadership nor the strength of the intervention.     

The shared leadership of teams: A meta-analysis of proximal,distal, and moderating relationships

The current meta-analysis examines the relationship between shared leadership and team performance. It also assesses the role of team confidence (i.e., collective efficacy and team potency) in this relationship. Mediation analyses supported the hypothesis that team confidence partially mediates the effects of shared leadership on team performance. We also found support for the notion that shared leadership explains unique variance in team performance, over and above that of vertical leadership. Furthermore, a variety of substantive continuous and categorical variables were investigated as moderators of the shared leadership–team performance relationship. Specifically, the relationship between shared leadership and team performance was moderated by task interdependence, team tenure, and whether performance was objectively versus subjectively measured. Finally, results suggest that the approach used when measuring shared leadership can also play a role in the observed validity. Theoretical and practical implications of these findings are discussed.     

Cultural and societal influences on shared leadership in globally dispersed teams

Leading globally dispersed teams poses critical challenges, especially if the team members are not only physically separated, but also culturally diverse and their tasks are dynamic and complex. It has been argued that shared leadership behaviors, such as continuous reflection, anticipation of a team's information needs, and initiating a team's social influence, positively influence virtual team performance. Country-level effects on shared leadership in globally dispersed teams, however, have been neglected. Building on the country institutional profile developed by Kostova (1997), we argue that regulative, cognitive, and normative components influence the likelihood that the individual will engage in shared leadership behaviors. Analyzing the differences between the institutional profiles of team members' home countries as reflected in institutional diversity as a team-level property, we furthermore point to different levels of institutional diversity as an enabling or hindering condition of shared leadership.

Examining the cross-level relationship between shared leadership and learning in teams: Evidence from China

The current study extends the literature on shared leadership by exploring the questions of whether, how, and when shared leadership makes an impact on team and individual learning behaviors. Specifically, the current research proposed that shared leadership has a positive impact on both team and individual learning and this impact was realized through the mediating role of team psychological safety. Furthermore, the study introduces job variety as a potential moderator in the relationships between shared leadership on team and individual learning behaviors through team psychological safety, such that the indirect effects are more positive when team members perceived high job variety. Using 263 members from 50 teams in China, the hypotheses were largely supported. Theoretical contributions, practical implications and future research directions are discussed.

Contextualizing LMX within the workgroup: The effects of LMX and justice on relationship quality and resource sharing among peers

While leader–member exchange (LMX) has evolved, a richer understanding continues to evade scholars due to the sustained focus on the leader–member dyad. We argue that LMX theory remains incomplete until contextual factors surrounding these pivotal relationships are accounted for including the impact of coworker exchange relationships, peer exchange, and perceptions of justice regarding individual LMX relationships. A fully crossed experimental design manipulating participant LMX and distributive justice and coworker LMX and distributive justice was employed to understand how these constructs affect coworker exchange relationships. Support was found for a causal model which specifies that justice moderates the causal relationship between LMX similarity and CWX, which subsequently leads to increased sharing of resources among coworkers. The data suggest that workgroup members are savvy to differences within individual leader–member relationships, where the sharing of resources among peers is determined by their own LMX, the LMX of their coworker and perceptions of justice of their respective LMX levels. These findings are contextualized in extant leadership research and practice.     

研发团队共享领导力行为的产生和对创新绩效的作用：基于垂直领导力的影响

 共享领导力是提高多元性、知识型的组织绩效的有效方式，但已有对研发组织领导力理论的研究大都侧重于垂直领导力对创新的影响，对共享领导力关注不足，而共享领导力作为一种随着团队发展而动态形成的领导力类型，已被证明是提高多元性、知识型组织绩效的有效方式；目前将共享领导力作为整体概念的研究思路能从宏观视角把握其作用机制，但不足以从微观层面揭示共享领导力的动态性的产生和作用。        基于领导力行为理论，从7个行为维度对共享领导力和垂直领导力进行解构，考虑垂直领导力的影响，从微观层面研究共享领导力的产生及对创新绩效的作用。运用访谈和参与性观察对4个研发团队进行全生命周期数据收集，通过多案例研究方法和规范的质性分析技术探究共享领导力行为在团队不同发展阶段的形成过程，以及垂直领导力行为对该形成过程的影响。区分创新绩效中的过程绩效、产品绩效和学习绩效，进一步揭示共享领导力和垂直领导力在促进不同创新绩效过程中发挥的不同作用。        研究结果表明，共享领导力不同行为的产生既直接依赖于垂直领导力，又通过依存环境间接依赖于垂直领导力；共享领导力的不同行为并非一次性形成，而是分别产生于团队生命周期的不同阶段，即在团队构建期首先形成跨边界领导行为，在成员磨合期形成激励行为和关怀行为，在规范执行期形成授权行为和变革领导行为；共享领导力行为的这种动态性决定了其直接作用于团队创新的学习绩效和产品绩效，对过程绩效没有直接作用，而垂直领导力行为则对过程绩效具有直接促进作用，并通过共享领导力间接作用于学习绩效。        在理论层面，从共享领导力行为角度分析其产生和作用，从微观层面挖掘其动态特性，解释了共享领导力和垂直领导力在促进创新绩效过程中的替代和互补关系，从而完善共享领导力的动态概念理论，也为后续的动态研究提供新思路。在实践层面，为研发团队管理中依据团队不同阶段和不同类型的创新绩效需求发展不同的共享领导力行为提供理论支持。     

Shared leadership across cultures: Do traditionalism and virtuality matter?

Shared leadership, in which the role of the leader is shared across team members, has great potential, yet little is known about the conditions under which it may be more or less effective across cultures. We examine traditionalism and the extent of virtuality as features which may change the relationship between shared leadership and team effectiveness, among 211 individuals working in 56 teams in a multinational aerospace design collaboration. We find a 3-way interaction between traditionalism, virtuality, and shared leadership in predicting team effectiveness. When traditionalism was high, virtuality was essential for shared leadership and team effectiveness. The theoretical contributions and relevance for managers in utilizing shared leadership are discussed.     

Leadership capacity in teams

The present article examines the state of the field regarding leadership in teams. A perspective is advanced that considers leadership as an outcome of team processes (e.g., teamwork and team learning) that provides resources for better team adaptation and performance in subsequent performance cycles. This perspective complements but does not replace the perspective of leadership as an input to team processes and performance. Specific facets of the teaming cycle are reviewed, including the nature of teamwork and interventions designed to facilitate its development, the role of team learning as different from individual learning, and relatively recent advances in understanding shared and distributed leadership (DL). These components of team leadership are cast within an emerging IMOI (inputs, mediators, outcomes, inputs) framework proposed for understanding the cyclical and ongoing nature of teams in organizations.     

Leadership emergence in face-to-face and virtual teams: A multi-level model with agent-based simulations,quasi-experimental and experimental tests

With leadership as a major predictor of team performance in both face-to-face and virtual teams, research on differences in leadership emergence in these contexts seems warranted. We offer a multi-level model analyzing the roles of degree of team virtuality and density of social network ties as boundary conditions on leadership emergence, viewed as a fundamentally social–cognitive process. Using agent-based modeling and simulations, our results suggest that virtuality moderates the relationships between cognitive ability, extraversion, and self-efficacy (as independent variables) and leadership emergence (as dependent variable); and density of network ties serves as a moderator for the associations of cognitive ability and self-efficacy with leadership emergence. Subsequent quasi-experimental and experimental tests support the role of density of network ties as a moderator for the association of extraversion with leadership emergence. Implications of these findings and future paths for research bridging the fields of leadership, team virtuality and social networks are discussed.     

Shared Leadership in Commercial Organizations: A Systematic Review of Definitions,Theoretical Frameworks and Organizational Outcomes

The importance of context has been well established in studies of leadership (Bryman, A. and Stephens, M. (1996). The importance of context: qualitative research and the study of leadership. Leadership Quarterly, 7, pp. 353–371; Pettigrew, A. and Whipp, R. (1991). Managing Change for Competitive Success. Oxford: Blackwell). However, recent reviews of shared leadership have tended to merge findings across commercial and non‐commercial settings, disregarding contextual differences in these distinctive domains. Acknowledging that the challenges of leadership may vary in different organizational contexts, this paper argues that a focused review of shared leadership in commercial organizations (COs) is needed. The authors thus systematically review findings from over twenty years of empirical research on the practice of shared leadership in commercial organizations, critically reviewing definitions, theoretical dispositions and measurement approaches adopted in the field, before evaluating the impact of shared leadership on performance in this context. Findings from commercial and non‐ commercial organizations are then compared, highlighting significant differences in the conceptualization of shared leadership in these distinct settings. Contributing to theory in this field, a framework is developed, mapping the landscape of current research in commercial contexts, revealing critical gaps in our present understanding of shared leadership processes. Consequently, a model summarizing a proposed research agenda for future studies is provided, highlighting the need for such research to focus on the interactions of individuals as they share in the leadership of their team.     

Leader-member exchange as a linking pin in the idiosyncratic deals - Performance relationship in workgroups

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups.     

When opposites do (and do not) attract: Interplay of leader and follower self-identities and its consequences for leader–member exchange

Employees' self-identities, or the ways in which they define themselves relative to others, have implications for the quality of leader and follower relationships at work. Although self-identity has been examined within the context of transformational and charismatic leadership, its relevance for leader–member exchange (LMX) has received little attention. In this study we integrate LMX and self-identity theories. Doing so proved useful because it was found that leader and follower identities predicted LMX quality, as did the fit between leader and follower identities and interactions among fit at different self-identity levels. LMX quality fully mediated relationships of self-identity fit with job performance, regardless of whether LMX was reported by subordinates or their supervisors. Lastly, we also found that self-identity predicted LMX agreement across supervisors and subordinates. Implications of our findings for theory and practice are discussed.     

Paternalistic leadership and employee voice in China: A dual process model

Drawing from social exchange and self-concept-based leadership theories, we investigate how paternalistic leadership — authoritarian, benevolent, and moral — affects employee voice from leader–member exchange (LMX) and status-judgment perspectives in the Chinese context. Data from 402 employees and their supervisors show that LMX and status-judgment mechanisms could work simultaneously in transmitting the influences of paternalistic leadership behaviors to employee voice. Authoritarian paternalistic leaders reduce employee voice by reducing their status judgment. Benevolent paternalistic leaders encourage employee voice by enhancing both LMX and status judgment. Moral paternalistic leaders positively influence employee voice mainly through LMX processes. We discuss theoretical and practical implications of the findings.
