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。     

Transformational leadership and ambidexterity in the context of an acquisition

This study explores the role of transformational leadership and the values incorporated in a learning culture in promoting ambidexterity (the ability to explore new capabilities while exploiting existing ones) in teams involved in acquisition integrations. Data from a field study of an acquisition integration (N = 71 work teams) support hypotheses arguing that transformational leadership behaviors and the development of a learning culture, characterized by psychological safety, openness to diverse opinions, and participation in decision making, promote ambidexterity at the team level. We also found support for the association between transformational leadership and learning cultures.     

Diabolical dictators or capable commanders? An investigation of the differential effects of autocratic leadership on team performance

Autocratic leader behavior is often seen as negative for team morale and performance. However, theories on social hierarchy suggest that autocratic leadership may also positively affect morale and performance through the creation of a psychologically appealing, hierarchically-ordered environment of predictability and security. We propose that autocratic leadership can foster team psychological safety when team members accept the hierarchy within the team. In contrast, when members challenge the hierarchy and engage in intrateam power struggles, autocratic leaders' centralizing power behaviors will clash with team members' competition for power and frustrate members, impairing psychological safety and performance. We find support for these ideas in a study of 60 retail outlets (225 employees and their managers) in the financial services industry. As expected, when team power struggles were low, autocratic leadership was positively related to team psychological safety, and thereby indirectly positively related to team performance. When team power struggles were high, autocratic leadership was negatively related to team psychological safety and thereby indirectly negatively related to team performance. These effects were also found when controlling for leader consideration.     

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.     

化被动为主动:共享型领导对员工主动变革行为的影响及作用机制研究

如何让员工将其工作角色外的行为,如主动变革行为,视为其角色内的行为越来越受到学者和管理者的关注。主动变革行为是指个体通过自愿的和建设性的努力来影响组织功能改变的行为,属于一种挑战性的组织公民行为。尽管以往研究对员工主动变革行为的影响因素进行了一些探讨,但主要聚焦于正式垂直领导和个体因素,鲜有研究关注团队情景因素对其的作用效果。通过问卷调查法,以69个部门和262名员工的配对数据为样本,本研究考察了共享型领导对员工主动变革行为的影响及作用机制。跨层次分析结果表明:(1)共享型领导对员工主动变革行为有积极影响;(2)主动变革行为的角色定义与和谐工作激情会分别中介共享型领导与员工主动变革行为之间的关系;(3)领导-成员交换质量会分别调节共享型领导与员工角色宽度自我效能与和谐工作激情之间的关系,领导-成员交换质量越高,共享型领导对员工角色宽度自我效能与和谐工作激情的积极作用越显著;(4)领导-成员交换质量会调节共享型领导通过角色宽度自我效能对员工主动变革行为的间接作用,领导-成员交换质量越高,这一间接作用越显著。     

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.     

Transformational leadership,job satisfaction,and team performance: A multilevel mediation model of trust

In spite of calls for deliberate differentiation between individual and team levels of analysis, leadership research based on well-grounded theory referring to multiple levels is scarce. We seek to fill this gap by analyzing the relations between transformational leadership, trust in supervisor and team, job satisfaction, and team performance via multilevel analysis. Results are based on a sample of 360 employees from 39 academic teams. Transformational leadership was positively related to followers' job satisfaction at individual as well as team levels of analysis and to objective team performance. The relation between individual perceptions of supervisors' transformational leadership and job satisfaction was mediated by trust in the supervisor as well as trust in the team. Yet, trust in the team did not mediate the relationship between team perceptions of supervisors' transformational leadership and team performance. Implications for theory and research of leadership at multiple levels as well as for practice are discussed.

The role of leadership in shared mental model convergence and team performance improvement: An agent-based computational model

Research in shared mental models has immeasurably aided our understanding of effective teamwork and taskwork. However, little research has focused on the role that leaders play, if any, in influencing, developing and/or fostering shared mental models and thereby improving team performance. We developed an agent-based computational model based on McComb's theory of three-phase mental model development, where agents repeatedly share individual opinions (orientation phase), evaluate and respond to the opinions expressed by others (differentiation phase), and modify their understanding of the team based on the responses (integration phase). Leadership and team properties are represented in three experimental parameters: social network structure, heterogeneity of agents' domains of expertise, and level of their mutual interest. Participative leadership is represented by a fully connected network, while Leader–Member eXchange (LMX) is represented by a fully connected network of in-group members and several out-group members connected only to the leader. Our simulation results show that, in general, participative leadership promotes mental model convergence better than LMX. In the meantime, the team performance improvement is achieved by participative leadership only when members have both heterogeneous domains of expertise and strong mutual interest. In all other conditions, participative leadership causes the worst degradation of team performance through team development processes, while LMX is the best to minimize such team degradation. Implications and suggestions for future research are provided.     

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.     

An empirical study of transformational leadership,team performance and service quality in retail banks

The discipline of operations management (OM) has long been offering differing quantitative techniques for improving the efficiency of banking operations. However, there has been a trend in recent years that operations and services of the banking industry are becoming more diverse and unstructured, rendering many traditional OM quantitative techniques less effective in performance improvement. By integrating the literature on banking operations, service quality, leadership style and work teams, we argue that leadership style and team performance are crucial concerns determining the service quality performance of today's banking operations in a team setting. Using data collected from 192 employees from 32 operational teams (a leader and five members in each team) in 15 retail banks in Macau, China, we investigated whether the five dimensions of transformational leadership have an impact on team performance with respect to team cohesion, team leader job satisfaction and team competence; and whether the dimensions of team performance have an impact on such service quality dimensions as reliability and responsiveness. We found that one of the dimensions of transformational leadership and two of the dimensions of team performance have a significant impact on service quality. We discuss the implications of the findings for research and practise.     

Leadership and team identification: Exploring the followers' perspective

This study investigates the influence of leadership on followers' identification with their work group. Adopting a qualitative research approach, it takes on the followers' perspective for inductively deriving leadership behaviors that pertain to the development of team identification. Based on in-depth data from members of seven teams in the context of UN peacebuilding operations, four aggregate leadership dimensions can be identified that are conducive to members' team identification: providing guidance, encouraging involvement, role modeling, and administering teamwork. Accordingly, this study adds to the exploration of leadership behaviors relevant for team identification that have not been considered by extant research. The results may lay the foundations for future investigations on complementary effects of different leadership behaviors for fostering followers' identification with their work group.     

Unpacking Team Familiarity: The Effects of Geographic Location and Hierarchical Role

Examination of team productivity finds that team familiarity, i.e., individuals' prior shared work experience, can positively impact the efficiency and quality of team output. Despite the attention given to team familiarity and its contingencies, prior work has focused on whether team members have worked together, not on which team members have worked together, and under what conditions. In this paper, I parse overall team familiarity to consider effects of geographic location and the hierarchical roles of team members. Using data on all software‐development projects completed over 3 years at a large Indian firm in the global outsourced software services industry, I find that team familiarity gained when team members work together in the same location has a significantly more positive effect on team performance compared with team familiarity gained while members were collaborating in different locations. Additionally, I find that hierarchical team familiarity (a manager's experience with front‐line team members) and horizontal team familiarity (front‐line team members' experience gained with one another) have differential effects on project team performance. These findings provide insight into the relationship between team experience and team performance.     

An integrative model of leadership behavior

Decades of questionnaire and interview studies have revealed various leadership behaviors observed in successful leaders. However, little is known about the actual behaviors that cause those observations. Given that lay observers are prone to cognitive biases, such as the halo effect, the validity of theories that are exclusively based on observed behaviors is questionable. We thus follow the call of leading scientists in the field and derive a parsimonious model of leadership behavior that is informed by established psychological theories. Building on the taxonomy of Yukl (2012), we propose three task-oriented behavior categories (enhancing understanding, strengthening motivation and facilitating implementation) and three relation-oriented behavior categories (fostering coordination, promoting cooperation and activating resources), each of which is further specified by a number of distinct behaviors. While the task-oriented behaviors are directed towards the accomplishment of shared objectives, the relation-oriented behaviors support this process by increasing the coordinated engagement of the team members. Our model contributes to the advancement of leadership behavior theory by (1) consolidating current taxonomies, (2) sharpening behavioral concepts of leadership behavior, (3) specifying precise relationships between those categories and (4) spurring new hypotheses that can be derived from existing findings in the field of psychology. To test our model as well as the hypotheses derived from this model, we advocate the development of new measurements that overcome the limitations associated with questionnaire and interview studies.     

Group leadership and shared task representations in decision making groups

The development of adequate shared understanding of the task is of critical importance to group functioning. Group leaders play an important role in this respect, as a key function of leadership is to shape group members' understanding of their job. In the present study we focus on decision making groups with distributed information and examine how group leaders shape members' mental representations of the group decision task through leadership behavior rooted in their own representations of the task. We propose that the extent to which the group leader has task representations that emphasize information exchange and integration affects group members' task representations, group information elaboration, and decision quality. We tested these hypotheses in an experiment (N = 94 three-person groups) in which we manipulated whether a group leader was present and whether this leader held representations emphasizing information elaboration. Results supported the hypotheses, and suggest that team leaders may play an important role in creating a socially shared understanding of team tasks.     

Exploration of the impact of organisational context on a workplace safety and health intervention

ABSTRACT

The Safety and Health Improvement Program (SHIP) was designed to increase workers’ safety and health using supervisor/leadership training. SHIP was implemented and evaluated in a cluster randomized controlled trial with 20 supervisors and 292 construction crew members representing a high-risk industry. The intervention had three components: (1) computer-based training to teach supervisors ways to better support worker safety and work-life challenges; (2) supervisor behavioural self-monitoring to facilitate transfer of training to practice; and (3) team-based discussions with supervisors and work crew members to identify challenges and opportunities for improvement with 30, 60, and 90 day follow-up check-in meetings. Main effects for the intervention on perceptions of family supportive supervisor behaviors, team effectiveness, and work-life effectiveness were not found, suggesting that the pre-intervention context could help explain the lack of intervention effects. We found that the intervention was more beneficial for work crew members who had poorer pre-intervention perceptions of their supervisor (lower leader-member exchange) and lower perceived team cohesion, suggesting the important impact of the organisational context on intervention effects. We argue that perhaps these work crews were more ready for change and improvements in functioning than were the crews that were already functioning well.     

Peers,proactivity, and problem-solving: A multilevel study of team impacts on stress appraisals of problem-solving demands

ABSTRACT

To date, there is a paucity of research on team-level impacts on the individual stress appraisal process despite the recognised role of teams for solving problems. Applying a multilevel approach, this study investigates the cross-level impact of team problem prevention behaviours on employee stress appraisals of problem-solving demands. It was hypothesised that team problem prevention would moderate the individual-level relationship between problem-solving demands and stress appraisals. Data were collected from 43 work teams comprised of 192 team members including all team leaders who also provided evaluations of their team’s problem prevention behaviour. Results supported the hypothesised cross-level moderating effects on challenge appraisal, but not threat appraisal. As one of the first studies to demonstrate that stress appraisals are impacted by the group, not just by individual factors, the results support a multilevel conceptualisation of stress appraisals. The findings also highlight implications for practice, broadening the scope of possibilities for stress management interventions to utilise team-level strategies such as leadership development programmes and/or team building initiatives.

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.
