Introduction

The notion of team members sharing leadership responsibilities is not a novel one, with researchers as early as the 1950s proposing the value of looking toward multiple leaders as a way to enhance group and team outcomes. However, there has been a recent revitalization of the topic, in large part driven by not simply a desire for leadership to be shared as a way to better empower and engage teams, but more so by the changing nature of work that has increased the responsibilities of leadership beyond the capacities of a single individual. Though the research on singular (i.e., vertical) leadership is thorough and extensive, the sharing of leadership as a collective, distributed, and/or networked construct has emerged as a critical component in the modern organizational world. While numerous terms have been used to define leadership involving multiple individuals, we utilize the term shared team leadership to encapsulate the most common terminology in management literature. The ever-changing environmental conditions of teams and organizations make the sharing of leadership critical for survival, especially when tasks are interdependent and complex. Moreover, team members actively involved in accomplishing team tasks and goals may best understand the complexity of the modern organizational setting. Thus, those individuals are often in the best position to recognize and address needs of leadership. The purpose of this article is to provide an introduction to the concept of shared leadership. Specifically, we offer summaries and resources regarding the history and trends in this area, with a particular focus on the numerous ways to define this form of leadership. Further, we provide guidance regarding the particular factors and associated resources that may serve to highlight relationships that have been studied regarding the inputs, processes/emergent states, and outcomes of shared leadership, as well as contextual factors that may serve to moderate its role in organizations. Further, we offer resources that provide guidance regarding the methodological issues surrounding the many operationalizations of shared team leadership. As the empirical work in the area of shared team leadership is still growing and relatively new, yet at the same time rather complex, we have included some references at multiple points within the article, but with different annotations regarding the reference’s relevance for that particular topic or subtopic.

History and Trends

In the development of the construct of shared leadership, there has been a need to distinguish what is meant by “shared leadership” and to make distinctions between it and similar constructs. Additionally, it is important to identify how shared leadership occurs and what variables influence it and what variables are influenced by it. These sections discuss the definitions of shared leadership and provide some models of how shared leadership works.

Definitions of Shared Leadership

The definition of shared leadership has been confounded by its use in a variety of distinct circumstances and often used interchangeably with other terms such as collective, distributed, and networked leadership. This section provides references related to the conceptualization of “shared leadership,” including the oldest reference and distinguishing between vertical and shared leadership and collective, distributed, and networked leadership.

Inputs: Team Composition and Individual Differences Influencing Shared Team Leadership

Team composition and individual differences examine the characteristics of the team and team members and shape how teams share leadership. Team composition encompasses both individual- and team-level factors, and the role of team composition within a given team will shift as team members are added, removed, or changed within a group.

Individual Factors

Teams are comprised of individuals who possess varying attributes that influence shared leadership processes and outcomes. Individual factors such as the personality of each team member and their leadership characteristics are notable for influencing how teams may share leadership. Within a team that aims to share leadership, each team member’s personality may play a pivotal role. Personality may be described in terms of the Big Five (i.e., openness, conscientiousness, extraversion, agreeableness, and emotional stability), in addition to other individual differences. Within teams that share leadership, it is important to consider not only the role of personality traits in isolation but also the interaction of numerous personality traits.

Team Factors

When considering the composition of the team, it is also important to consider the role that various characteristics of the team may play in shaping how individuals share leadership within a team. Several team level factors, such as diversity within the team, team tenure, and team size, may influence team-shared leadership.

Team Cultural Diversity

As the workforce becomes more globalized, teams spanning across geographic bounds has become a commonality, resulting in culturally diverse team composition. However, cultural values within a team may vary not only due to geographic dispersion, but also due to varying values within the same culture. While few studies have considered cultural diversity and shared leadership, those that have tend to focus on the distinction between individualism and collectivism, with collective cultures tending to share leadership.

However, the nationalities included and the respective team composition of these nationalities were not specified in the study due to the large number of unique nations represented.

Team Tenure

Meta-analytic results reveal that team tenure moderates the relationship between shared leadership and team performance, such that as team tenure increases, the relationship between shared leadership and performance becomes weaker, as discussed in Nicolaides, et al. 2014. These results indicate that it may be difficult to sustain the positive effects of shared leadership over time. However, current studies that include team tenure in their analyses have only used them as a control variable, highlighting the need for additional research in this area.

    Nicolaides et al.’s meta-analytic investigation notes that few studies have considered the role team tenure plays on shared leadership within formal hypotheses, but that many studies tend to control for it.

Team Size

Meta-analytic results reveal that team size is unrelated to shared leadership directly, but it was not assessed as a moderator of the shared leadership and performance relationship due to a lack of primary sources reporting team size statistics (e.g., mean, variance; Nicolaides, et al. 2014). Further, the shared leadership studies that do include team size tend to only use it as a control variable. Therefore, future research should take a closer look at this phenomenon to understand the impact that team size may have on shared leadership and performance.

Team Processes and Emergent States Associated with Shared Team Leadership

Team processes and emergent states are potential mediating variables in the input-process-output (IPO) model. In comparison, emergent states serve to provide insight toward member attitudes, values, and motivations. Shared leadership emerges in team processes by rotating leadership among members in order to capitalize on the individual knowledge and skill needed to accomplish a goal, as explained in Fausing, et al. 2015. Both influences are demonstrated to be essential antecedents for shared leadership behaviors.

Team Emergent States

Emergent states are cognitive, motivational, and affective states of teams, which are considered both team inputs and subsequent outcomes. These represent distinct constructs comparative to team interactions or actions that likewise lead to various important outcomes. Emergent states are those factors that result from team interactions (including team processes) and, in turn, function as inputs to proximal processes and outcomes. Shared leadership behaviors become a function of the cyclical nature underlying team dynamics. These sections will discuss the research associated with the impact of various emergent states in shared leadership environments.

Team Attitudes/Affect

Shared leadership describes a relational process among individuals and influences member perceptions to share responsibilities and roles within the team, thus playing an important role in shaping overall team attitudes, as discussed in Liu, et al. 2014. Psychological empowerment is characterized by being feeling more motivated at work, and therefore more willing to take action, as documented in Grille, et al. 2015. Further, in regard to other team affective states, shared leadership has been studied in relation to the psychological safety of learning environments in traditional organizational teams, as well as the degree to which cohesion may show differential effects in relation to shared leadership. Finally, by engaging in shared leadership activities, trust has been shown to increase, as has the efficacy of the team as members put aside their own personal goals for the greater good of the team.

    Avolio et al. provide a conceptual framework and measurement approach regarding team development processes. Implications of the study suggest that in shared leadership, it is necessary that individual members go beyond a self-interested, narrow view of their role in order to enhance their overall commitment to the team’s purpose. Consequently, members may increasingly engage in leadership behaviors and transfer functions among the team to achieve the shared goal.

    Daspit et al. examine the internal factors underlying cross-functional team (CFT) effectiveness, where team members belong to different operative areas within a system. The findings suggest that the internal team environment encourages members to partake in shared leadership, but there is no direct relationship among shared leadership and cohesion, dissimilar to traditional team research. The lack of support for this relationship may be due to leader’s unique expertise of their role.

Team Cognition

Team cognition is a necessary function in shared leadership where members should have congruent conceptions of the knowledge and procedural skills comprising their team. In the team literature, shared mental models are formally defined as the degree to which long-term memory structures held by team members are aligned, such that there is substantial agreement that, in turn, guide the coordinated actions involved in transferring leadership functions, as seen in Burke, et al. 2003. The emergent nature of team cognition requires the prerequisite of team members having awareness of the shared expectations gathered from mental models before these expectations can be acted upon, as explained. In addition, these models must be flexible in a way that members do not conform to rigid social norms, which could restrict strategy formulating or updates in mental models.

Team Processes

Team processes are the means through which taskworks are directed and monitored in pursuit of team goals. Shared leadership emerges in team processes and involves the rotation of leadership to the team member who possesses the necessary resources and skills to solve a given task.

Action- and Transition-Focused Behavioral Processes

Shared leadership theory suggests that formal leadership functions are replaced by a team’s more informal approach of self-managing behaviors. Such behaviors encourage team members to resolve task- and teamwork-related problems through resources internal and external to the team environment, as discussed in Morgeson, et al. 2010.

Interpersonal and Conflict Processes

Intra-team conflict may have detrimental consequences for team task functioning and relationship functioning.

Outcomes of Shared Leadership

Just as shared leadership has many antecedents and processes associated with its full conceptualization, there are many outcomes that can result from engaging in shared leadership. These outcomes can be separated based on their level of analysis. The first level includes aggregated team/organizational outcomes, while the second level includes individual outcomes. Each level of analysis may be useful in the pursuit of answering a diverse set of research questions.

Team/Organizational Outcomes

One level where shared leadership has an impact is in teams and the organizations made up of those teams. Through an understanding of how shared leadership impacts such higher-order units, the influence of these leadership behaviors can be generalized and understood in a broader context. These diverse outcomes at the team and organizational level include performance/effectiveness, learning, satisfaction, problem-solving, and creativity/innovation.

Team Performance and Effectiveness

The performance and effectiveness of a team are vital to ensuring the accomplishment of the goals that the team is tasked with completing. Shared leadership may be one way in which these two related team outcomes can be more successfully achieved. It is through sharing leadership that goals become more relevant to employees, allowing workers to more closely identify with their goals and perform at their best.

Individual Outcomes

A second level that can be studied to understand the outcomes of shared leadership is that of individuals. While team and organizational outcomes depict the big picture of shared leadership outcomes and influences, individual outcomes can give researchers a more nuanced idea of how those aggregated relationships came to be. Individual outcomes that have been studied in the context of shared leadership include emergence and satisfaction.

Individuals’ Emergence as Leader(s)

Emergence is a process that results in group members having peer recognition of leadership status. Leadership emergence does not necessarily imply the emergence of a single leader, however. In groups characterized by shared leadership, such leadership inherently emerges for multiple different people at different times.

Moderators of the Shared Leadership and Outcomes Relationship

As seen in the section on Individual Outcomes, knowing how shared leadership influences outcome variables of interest is of great organizational importance. However, this relationship is rarely straightforward. Moderators of the relationship between shared leadership and its outcomes can provide a greater comprehension of when such leadership is most effective and how it can be tailored to increase its efficacy. Moderators include the environmental context, team context, and individual context.

Environmental Context

Shared leadership does not exist in a vacuum. Rather, it is influenced by a variety of situations and contexts. Moderators that fall into the environmental context are those that are influenced by the organization as a whole. These include organizational culture and organizational structure.

Organizational Culture

Organizational culture refers to shared values, norms, and practices of behavior and has been shown to affect the success of shared leadership in business. For shared leadership to be successful in an organizational culture, that culture must embody collaboration, trust, and reciprocal accountability.

  • Erkutlu, H. “The Impact of Organizational Culture on the Relationship between Shared Leadership and Team Proactivity.” Team Performance Management 18.1–2 (2012): 102–119.

Team Context

While the environmental context plays an external role in influencing shared leadership, the team context plays an internally influential role. This team context includes elements of task complexity and task/team interdependence.

Team Task Complexity

Task complexity imposes demands on the knowledge, skills, and abilities of team members. It is theorized that as the task becomes more complex, there is a lower likelihood that any one individual team member can complete all parts of the task. Thus, task complexity is posed as one potential moderator of the shared leadership and performance relationship.

Team Interdependence

Task interdependence in teams is the extent to which team members must rely upon one another to accomplish their tasks and subsequent team goals. It is often argued that the benefits of shared leadership are greatest in certain contexts that are characterized as interdependent. These studies seek to explore this potential moderator.

Individual Context

In addition to team context, individual context plays an internal role in moderating shared leadership’s relationship with outcome variables. The individual context, however, is a more basic unit of analysis compared to the aggregated team context.

    Hoch et al. explored the moderating effect of age diversity and team coordination on the relationship between shared leadership and team performance. Results indicated that shared leadership predicted team performance. Both age diversity and coordination moderated the impact of shared leadership on performance, such that strong effects of shared leadership on team performance were evident when age diversity and coordination were low, but shared leadership was not related to team performance when both age diversity and coordination were high.

Measurement Considerations for Shared Team Leadership

There are numerous measurement considerations to make when assessing shared leadership within a team. Early approaches to assessing shared leadership tended to apply aggregate measures, while later methods employed social network analysis, which encompasses more advanced techniques such as (de)centralization and density. Such studies have been conducted both within the lab and in the field to reveal the benefits of shared leadership across various contexts. However, future research should consider the advantages and disadvantages that each of these approaches provides given their research context to further advance our understanding of shared leadership.

Aggregating and Level of Analysis as Considerations in Shared Leadership Research

Aggregate measures of shared leadership apply concepts of individual leadership behaviors to the team level to assess shared leadership and assumes that the entire team is the source of leadership. This method has team members rate their overall team on how well the team exhibits shared leadership and then aggregates these assessments to the team level.

    The authors modified the Pearce and Sims 2002 questionnaire and concluded that shared leadership is comprised of four dimensions: directive, transactional, transformational, and empowering leadership. In aggregate assessments of shared leadership, team members would rate the degree to which the team performed each of these dimensions.

Networked Metrics to Operationalize Shared Team Leadership

When considering shared leadership, network measures apply social network analysis to understand the relationships between members within a team. This approach considers the degree to which each team member may partake in leadership processes. These measures often require the team to rate all of their team members on a particular assessment, such as how often each member performs a set of leadership functions. Then the ratings are used to calculate the degree of (de)centralization and density within the team.

(De)centralization Metrics

Centrality identifies an individual’s position within the team in terms of their relationships with other members within that team, where central team members have many relationships/ties with other actors. Individuals in central positions (i.e., high centrality score) within a network tend to emerge as leaders of the group, as explored, with numerous members citing them as a leader. In contrast, low centrality scores indicate that there is no clear leader or that everyone in the team is proving leadership. Thus, teams that share leadership have low centralization scores, or exhibit (de)centralization.

    Erez et al. revealed that student teams with rotated leadership had higher levels of voice, cooperation, and performance than teams with leader emergence. Rotated leadership was an assigned condition where teams were instructed to have different leaders for each project; therefore, shared leadership was not formally assessed.

    Contrary to many studies, they found that decentralization of leadership was not significantly related to performance, but, most notably, found that different decentralized leadership structures were more related to better team performance than others. Thus, highlighting the need considers not only the degree of (de)centralization, but the structure of leadership within a team.

Density Metrics

Density refers to an individual’s ties in comparison to all possible ties, or the percent of ties an individual has, and team density is calculated by taking the aggregate of the team members’ individual density scores. In high-density teams, individuals exhibit ties with the majority of their team members, where “complete” networks exist when all possible ties within network are present. When applying density to assess shared leadership, teams that rate all members as exerting leadership influence in the team would be considered dense.

Research Design Issues for Investigating Shared Team Leadership

The next methodological concern for assessing shared leadership considers the contextual factors that are a part of the design for different research studies. As is common in organizational research, the majority of shared team leadership studies have been conducted as cross-sectional studies, ignoring the implications that shared leadership may have temporally within a team. Further, it is also important to consider the varying effects that the type of sample utilized may have on the relationships that emerge with shared leadership.

Longitudinal and Dynamic Aspects of Shared Team Leadership

While meta-analytic results reveal that the effects of shared leadership on performance may dissipate overtime, there is little consensus on why these results may occur or what the true role of shared leadership within a team may be in the long term. By evaluating varying antecedents and outcomes over time, longitudinal assessments help depict the role that shared leadership plays within a team and why this role may shift temporally.

The Role of the Study Setting (Lab, Field)

While labs provide a controlled environment to study phenomena, they are often critiqued for failing to be representative of organizational settings. Meta-analysis reveals that labs tend to have smaller effect sizes than organizational settings for the relationship between shared leadership and performance and may provide a conservative sample for testing shared leadership (D’Innocenzo, et al. 2016).

    Boies et al. conducted this on undergraduate students in an upper-level strategy course where students participated in a business simulation task over the duration of the semester. They found that both team trust and potency are antecedents of team-shared leadership. However, this laboratory-based study did not find a significant relationship between shared leadership and performance, which may be due to the conservative estimates that laboratory-based samples could provide.

Determining the Appropriate Operationalization for Shared Team Leadership Studies

There are numerous approaches to assessing shared leadership. However, it is important to understand when to apply each approach for different research questions. While aggregate approaches may be appropriate in some situations, understanding when and why to employ network centrality and density assessments should be key focal questions, as researchers continue to research shared leadership.
