What Is the Distributed Leadership Model?

The distributed leadership model holds that leadership is not a set of traits belonging to one designated person, but a practice that plays out across multiple people, in interaction with each other and with the tools, routines, and structures of an organization. Rather than asking “who is the leader,” distributed leadership asks “how does leadership work get done here, and who is involved.”

This is a genuine shift in unit of analysis. Traditional leadership theories, from trait theory through transformational leadership and transactional leadership, focus on an individual leader’s behavior, style, or relationship with followers. Distributed leadership instead treats the group, the interactions, and the situation as the thing worth studying. The International Encyclopedia of Education frames this directly: leadership under this model is understood at the level of the group, arising from the joint activity of several people acting together rather than from one individual’s decisions alone.

What makes this genuinely useful, rather than just a rebranding of teamwork, is that it gives researchers and practitioners a way to actually trace where leadership activity happens. Instead of assuming the principal, CEO, or ward manager is the sole source of direction, a distributed lens follows the activity itself: who called the meeting, who set the agenda, who has the expertise that others defer to on a given task, and how the routines of the organization carry leadership work between people.

Why “Distributed” Rather Than “Shared” or “Delegated”?

The word choice matters. Distributed signals that leadership is stretched, or spread, across people and artifacts as a natural condition of complex work, not as a deliberate act of generosity by a single leader. In the broader academic synthesis of the field, a leader under this model is anyone whose everyday actions influence the motivation, knowledge, or practice of colleagues, with that status coming from the task at hand rather than from a formal position on the org chart. That is a meaningfully different starting point than simply saying a leader delegated tasks to the team.

This distinction becomes important later when comparing distributed leadership with shared leadership and simple delegation, both of which are often used interchangeably with it in casual writing but rest on different assumptions about hierarchy and intent.

Where the Theory Came From: Spillane, Gronn, and Harris

Distributed leadership did not arrive fully formed. It has a specific intellectual lineage worth knowing if you are writing about it academically, because examiners and reviewers expect the theory to be attributed correctly.

James P. Spillane and the Distributed Leadership Study

James P. Spillane, a professor at Northwestern University, is the figure most closely associated with the contemporary theory. His Distributed Leadership Study examined how leadership practice actually unfolded inside Chicago-area elementary schools. Spillane’s central claim, drawn directly from his fieldwork, is that leadership practice gets built through the back-and-forth interaction of two or more leaders working together, and that the tools, routines, and structures surrounding them are not simply accessories that make a leader more efficient. They actively help define what the practice of leadership even is.

This is a subtle but important point. In Spillane’s framing, a school improvement planning process or a five-week assessment routine is not just a container that leadership pours into. The routine itself shapes what leadership looks like, because it determines who talks to whom, what data gets seen by which people, and what decisions become possible at what moments. His 2006 book Distributed Leadership and the 2007 follow-up with John Diamond, Distributed Leadership in Practice, remain the two most cited texts in the field.

Peter Gronn and Concertive Action

Peter Gronn approached the same idea from a different angle, focused on what he called concertive action. Gronn argued that distributed leadership offered researchers a genuinely new unit of analysis, one that let leadership be studied as a whole rather than treated as a simple sum of separate individual contributions. His taxonomy distinguished conjoint agency, where two or more people’s actions become fused into a single leadership event, from numerical action, where individual acts of leadership are simply added up.

Gronn identified three forms this conjoint agency could take, as summarized in a review published in the International Journal of Management Reviews: spontaneous collaboration, intuitive working relationships built up over time between colleagues, and institutionalized practices formally built into how the organization runs. All three, Gronn argued, require interdependence and coordination between the people involved.

Alma Harris and the Policy Turn

Alma Harris extended the theory from an analytical tool into something education systems could adopt as policy. Her work, described in a retrospective published in the journal School Leadership and Management, describes distributed leadership as an extended, collective practice that centers on how people depend on and coordinate with one another, rather than on any one person acting independently. Through the 2000s and 2010s, this more prescriptive reading of distributed leadership gained real traction with policymakers across the UK, the United States, Australia, several European countries, and New Zealand, with Wales building it directly into its 2012 national school effectiveness framework and England folding it into workforce remodeling reforms.

This policy adoption is worth flagging as a genuine tension in the literature. Spillane’s original work was descriptive, an attempt to understand what leadership practice actually looked like on the ground. Harris and the policy movement that followed treated distributed leadership as prescriptive, something organizations should deliberately install to improve outcomes. Both readings appear in the academic literature, and conflating them is a common source of confusion in student essays.

The Core Ideas Behind Distributed Leadership

Three ideas recur across nearly every serious treatment of the distributed leadership model, and understanding them together is what separates a surface-level definition from genuine command of the theory.

Leadership Is Stretched Across People

The first idea is that leadership practice is stretched, distributed, over the work of a number of individuals. This does not require formal authority. A subject-matter expert without a management title can be exercising real leadership if colleagues defer to their judgment on a specific task. Spillane’s fieldwork found this pattern clearly: leadership routines for literacy at one school he studied involved the principal, a literacy coordinator, a curriculum specialist, and lead teachers acting together, while mathematics leadership routines at the same school were carried almost entirely by four lead math teachers, without the principal directly involved at all.

Leadership Is Stretched Across Situation

The second idea is that tools, routines, and organizational structures are not neutral backdrops. They actively shape leadership practice. A weekly grade-level meeting, a shared spreadsheet of student assessment data, or a whiteboard used for daily huddles all carry part of the leadership work. Change the tool or the routine, and the leadership practice itself changes, even if the same people remain in the same roles.

Leadership Is Not an Activity, It Is a Practice

The third idea, drawn from the broader academic synthesis of the field, is that distributed leadership is best understood as an ongoing procedure rather than a single discrete activity. Leadership, in this reading, is made up of the everyday actions tied to an organization’s core work that its members carry out specifically to shape the motivation, knowledge, or practice of their colleagues. Under this definition, a leader is simply anyone performing these actions, regardless of job title, and the people affected become the followers, at least for that specific interaction.

Distributed Leadership vs Shared, Delegated, and Transactional Leadership

Students and practitioners regularly conflate distributed leadership with adjacent models. The distinctions carry real analytical weight, and getting them right is one of the more commonly tested skills in leadership coursework.

Distributed Leadership vs Shared Leadership

The two terms are frequently used as synonyms, but they rest on different assumptions. Distributed leadership is primarily descriptive and analytical. It asks how leadership practice actually unfolds, and it does not require that authority be equal among participants. Shared leadership, by contrast, tends to be normative: it holds that decision-making power should be spread roughly evenly across team members, whereas a distributed model can retain a designated leader who delegates specific tasks while still coordinating overall direction.

A useful practical distinction comes from an organization that has actually run both models side by side: they describe distributed leadership as decision-making dispersed across everyone on the team, and shared leadership as the sharing of influence and power while one person still remains formally in charge. In other words, shared leadership can coexist with a named leader who holds ultimate accountability; distributed leadership pushes further, questioning whether a single locus of decision-making needs to exist at all for a given task.

Distributed Leadership vs Delegation

Delegation is narrower than either model above. It describes a single leader handing off specific tasks while retaining ultimate authority and decision rights. A team-development consultancy draws the line clearly, arguing that distributed leadership goes well beyond assigning tasks and is really about empowering others to act as genuine leaders in their own right, which means trusting them with real responsibility rather than simply handing down work while keeping all actual decision power at the top.

This matters because delegation leaves the underlying leadership structure hierarchical and unchanged. Distributed leadership, at least in its stronger forms, questions whether that hierarchical structure is even the right frame for understanding how the work gets done.

Distributed Leadership vs Transactional and Transformational Leadership

Both transactional leadership and transformational leadership are built around the behavior and style of an individual leader, whether that means managing exchanges of reward and performance, or inspiring followers toward a shared vision. Distributed leadership sits at a different level of analysis entirely. It does not compete with these models on the question of “what should a leader do.” It challenges the premise that a single leader is the correct unit to study in the first place. A school or hospital could, in principle, exhibit transformational leadership qualities distributed across several people rather than concentrated in one.

For a fuller comparison of individual-leader models, see the guides on servant leadership, authentic leadership, and situational leadership, all of which remain focused on a single leader’s traits, values, or adaptive style rather than the group-level unit of analysis distributed leadership uses.

Key Characteristics of a Distributed Leadership Model

Across the education, healthcare, and business literature on distributed leadership, a handful of recurring characteristics separate genuinely distributed arrangements from simply well-run teams with good delegation.

Interdependence Between Leaders

Genuine distributed leadership requires that the actions of one leader enable, or are shaped by, the actions of another. Spillane called this reciprocal relationship “collaborated distribution,” and compared it to a partner dance, where one person’s movement only makes sense in relation to the other’s. This is distinct from parallel leadership, where two leaders simply run separate parts of an operation without their actions actually depending on each other.

Role Space Beyond Formal Position

A team member without a formal title can occupy real leadership “role space” if their expertise or relationships give them genuine influence over how work gets done. Research on distributed leadership in organizations, published in Leadership Quarterly and reviewed extensively by Bolden, identifies role space as one of the key dimensions separating shared-distributed leadership, where team members occupy the same role space together, from dispersed-distributed leadership, where different individuals occupy entirely separate role spaces across the organization.

Boundary Conditions and Limits

Distributed leadership is not infinitely elastic. Research on the model in health and social care settings, examining the boundary conditions of the concept, found that highly regulated, hierarchical professional structures such as clinical governance systems place real limits on how far leadership practice can actually be distributed, regardless of organizational intent. A hospital cannot distribute prescribing authority the way a school can distribute curriculum planning, because professional licensure and legal accountability constrain who can exercise certain forms of leadership, no matter how collaborative the culture becomes.

Distributed Leadership in a Chicago School District

The clearest empirical case study of distributed leadership in practice comes directly from Spillane’s own fieldwork inside Chicago-area elementary schools, the setting where the modern theory was built and tested.

What the Chicago Study Revealed About Tools and Routines

Spillane also documented how specific artifacts carried leadership practice at Hillside School in Chicago, where the principal used student writing samples as a tool to structure conversations between teachers about instructional quality, rather than delivering top-down instructional judgments directly. The tool itself, not just the principal’s authority, became part of how leadership was enacted.

The broader retrospective published in School Leadership and Management describes how, within roughly a decade of Spillane’s original study, distributed leadership had already been taken up enthusiastically by education policymakers in several countries, including the UK, the United States, Australia, parts of Europe, and New Zealand. Reforms in Wales wrote it explicitly into the 2012 national school effectiveness framework, and England’s workforce remodeling policies built distributed structures into new models of schooling such as federations and multi-agency partnerships.

For students writing about educational leadership more broadly, comparing distributed models against other frameworks like path-goal theory or laissez-faire leadership can sharpen the analytical contrast between models built around a single leader’s behavior and models built around group-level practice.

Distributed Leadership in the NHS: The Salford Royal Physiotherapy Case

Healthcare provides a genuinely different testing ground for distributed leadership, because clinical settings combine strict professional hierarchies with the kind of complex, expertise-dependent coordination that distributed models are meant to explain.

Why Healthcare Tests the Limits of the Model

Distributed leadership research in healthcare settings has been notably thinner than in education. A systematic review published in Health Services Management Research points out that the concept has rarely been given a precise empirical definition or studied in real depth outside of education, and that comparatively little research directly links change leadership to outcomes in healthcare, even though pluralistic, public-sector organizations like the NHS create exactly the kind of complex conditions where distributed patterns would be expected to matter most.

The same review, drawing on ten comparative case studies of NHS improvement projects under a program focused on early cancer diagnosis, found a connection between broadly distributed change leadership and improved service outcomes, while also finding that professional and managerial hybrid staff performed crucial lateral facilitation roles connecting clinical and managerial leadership. This hybrid role, sitting between formal clinical authority and formal management authority, is a distinctly healthcare-specific expression of distributed leadership that has no close equivalent in the education case studies.

Students researching healthcare leadership assignments can find additional grounding in nursing leadership resources and management and leadership in nursing, both of which cover how clinical hierarchy interacts with collaborative leadership practice.

Distributed Leadership in Swedish Eldercare: Six Workplaces Compared

A 2025 study published in BMC Health Services Research offers one of the most methodologically careful recent applications of distributed leadership theory, examining six eldercare workplaces in Sweden through what the researchers call a realistic evaluation design.

The Lesson: Same Policy, Different Practice

What makes this case study valuable for students is precisely the finding that six workplaces, all nominally implementing the same distributed leadership policy in the same national eldercare system, produced meaningfully different forms of distribution in practice. This directly supports Spillane’s original theoretical point: leadership practice is not simply installed by policy directive. It emerges from the specific interaction of people, tools, and local routines, which is why the same organizational reform can look entirely different from one site to the next.

Distributed Leadership Outside Education: Business Applications

Although distributed leadership theory was built inside classrooms and school districts, the underlying logic travels reasonably well into business and organizational settings, provided the specific vocabulary translates carefully.

Cross-Functional Product Teams

Technology companies organized around cross-functional squads, where product management, engineering, and design leads jointly own a roadmap, exhibit a business-world analogue to Spillane’s literacy leadership pattern: multiple actors, no single dominant decision-maker, and coordination carried substantially by shared tools like sprint boards and roadmap documents rather than by a single manager’s individual authority.

Harvard Business Review’s Framing

A frequently cited summary of the concept for business audiences points to Harvard Business Review’s framing of the idea: distributed leadership goes well beyond delegation, resting instead on a team that shares a genuine sense of purpose and joint responsibility for how the company as a whole gets led. Different people may take the lead on different parts of the work, but responsibility for the overall direction never sits with just one person. This framing captures the core distinction from delegation covered earlier: authority is not handed down from one source, it is genuinely distributed according to expertise and context.

Trust as the Operating Constraint

Business-oriented commentary on distributed leadership consistently returns to trust as the binding constraint on how far distribution can go. One analysis frames the underlying shift plainly: the manager’s job stops being about deciding for others and becomes about creating the conditions that let others decide well, while still holding onto responsibility for overall direction and purpose. That same source warns that when the shift is poorly prepared, distributed structures can spawn too many uncoordinated mini-leaders, causing the organization to lose overall coherence, or leave roles and responsibilities so vague that the result is stress and inertia rather than genuine empowerment.

For students building out organizational behavior essays, this connects directly to broader coverage of organizational culture, leadership and change management, and network versus hierarchical organizational structure, all of which shape how far a distributed model can realistically extend inside a given company.

Advantages and Challenges of Distributed Leadership

No leadership model is free of trade-offs, and the case studies above already hint at where distributed leadership tends to succeed and where it tends to strain.
