Change management models: what Lewin, Kotter, and Kanter still teach us today

Why rely on theoretical models to manage change? It is a valid question, especially as transformations accelerate and digital tools promise faster and faster solutions. The answer is simple: because human behavior in the face of change follows stable patterns, which theorists have patiently documented for over seventy years.

Change management models are not recipes—they are maps. They do not tell you where to go, but they help you understand the terrain, spot predictable obstacles, and choose the most suitable levers for every situation. Provided, of course, that you read them with a critical eye and know how to adapt them to each organization's unique context.

Here are the three most frequently cited, taught, and utilized models in change management practices: Kurt Lewin's, John Kotter's, and Rosabeth Moss Kanter's.

Kurt Lewin’s Model: Unfreeze, Change, Refreeze

Kurt Lewin is often considered the parent of social psychology applied to organizations. In the 1940s, this German-born psychologist who sought refuge in the United States laid down theoretical foundations for group dynamics and organizational change that remain remarkably relevant today.

His most famous contribution is the three-phase model, published in 1947 in his article Frontiers in Group Dynamics. This model relies on a simple and powerful metaphor: change is like reshaping a block of ice. To change it, you must first melt it, give it a new shape, and then let it solidify in this new configuration.

Phase 1: Unfreeze

The first phase is about creating the psychological and organizational conditions that allow change to happen. Lewin observed that individuals and groups naturally tend to maintain an equilibrium—a relative state of comfort built on habits, routines, and shared norms. For change to be possible, you must disrupt this balance.

In practice, unfreezing means creating an awareness of the need to change, communicating the reasons behind it, and reducing resistance before trying to overcome it. This is the most underestimated phase in transformation projects: all too often, we rush into action without truly preparing the human ground. Based on Kotter’s research, this lack of preparation is one of the leading causes of project failure.

Phase 2: Change

The second phase is the actual change itself: you implement new practices, test new behaviors, and roll out new tools. This is the most visible phase, and often the best planned, but it is also where the strongest resistance emerges.

Lewin emphasized a crucial point: change cannot simply be decreed. You build it through interaction between individuals and their environment. This is why he advocated for participatory approaches, gradual experimentation, and continuous support rather than an imposed, unilateral transformation.

Phase 3: Refreeze

The third phase is stabilization. You must firmly anchor the new behaviors and practices into individual habits and collective norms. Without this phase, change remains superficial and fragile: as soon as the pressure eases, people return to their old ways.

Refreezing means celebrating successes, formalizing new practices within processes and tools, training teams for the long term, and aligning recognition and evaluation systems with the new expected behaviors.

What Lewin Offers Us Today

The strength of Lewin's model lies in its simplicity and psychological depth. By reminding us that change begins with an unfreeze, he prompts supervisors to evaluate human readiness before technical deployment. By emphasizing refreezing, he highlights one of the most common oversights in transformation projects: prematurely abandoning support once the new practices are formally in place.

Its main limitation is that it was designed for separate, sequential changes, whereas today's organizations navigate simultaneous and permanent transformations. However, the model remains an indispensable lens for structuring each wave of change, even in a context of continuous acceleration. 

John Kotter’s Model: The 8 Steps to Successful Change

John Kotter is a professor at Harvard Business School and one of the most influential researchers in change management. His 8-step model, published in his 1996 book Leading Change, comes from an in-depth analysis of over one hundred organizations undergoing major transformation projects. He identified the most common mistakes leading to failure and used them to define the conditions for success.

His initial finding is revealing: according to his research, nearly 70% of change projects fail. Not because they are poorly designed technically, but because they fail to engage people. His model serves as a direct solution to these failures.

The 8 Steps in Detail

•        Establish a sense of urgency: convince enough people that the status quo is riskier than change. Without this shared sense of urgency, no transformation project can find the energy needed to start.

•        Create a powerful guiding coalition: bring together an influential, legitimate group of people to drive the change. This coalition must combine formal authority, expertise, credibility, and informal leadership.

•        Develop a clear vision and strategy: articulate a future state that is clear and inspiring enough to guide decisions and actions. A vague vision generates confusion, not commitment.

•        Communicate the change vision: use every available channel to share the vision repeatedly and consistently. Kotter emphasizes an often-forgotten principle: leaders must personally embody the vision in their daily actions.

•        Empower broad-based action: identify and remove structural barriers to change, whether they are organizational (processes, evaluation systems), managerial (supervisors slowing down change), or cultural (norms incompatible with new expectations).

•        Generate short-term wins: plan and create visible, rapid successes that prove the change is working. These early wins maintain motivation and disarm skeptics.

•        Consolidate gains and produce more change: use the credibility of your first wins to launch new change initiatives and deepen the transformation. Avoid declaring victory too early.

•        Anchor the changes in the culture: embed new practices into the organization's norms, values, and systems to ensure they last. Change only sticks when it becomes "the way we do things around here."

What Kotter Offers Us Today

The strength of Kotter’s model is its operational focus. While Lewin offers an understanding of psychological dynamics, Kotter provides a structured action plan with sequential steps and concrete points of attention. His focus on the guiding coalition and short-term wins is incredibly valuable for managers handling complex transformations.

Its primary limitation is the linear, sequential nature of the model, which was built for planned and relatively stable transformations. In 2014, Kotter himself updated this perspective, proposing a dual model: a traditional hierarchical system for daily operations, complemented by a more agile network system to drive transformations. This evolution demonstrates how well the model adapts to contemporary realities. 

Rosabeth Moss Kanter’s Model: The Ten Commandments of Change

Rosabeth Moss Kanter is a professor at Harvard Business School and one of the most influential figures in management since the 1980s. A sociologist by training, she brought a unique perspective to change management by focusing specifically on the organizational and cultural conditions that allow transformations to succeed or fail.

In her 1983 book The Change Masters, she identified the traits of organizations capable of continuous innovation and transformation. From this, she created a list of ten commandments, often presented as a practical guide of what to do and what to avoid in any change project.

Kanter’s Ten Commandments

•        Analyze the organization and its need for change: understand the underlying reasons for change, not just the surface-level issues.

•        Create a shared vision and common direction: bring meaning to the change by connecting it to the values and aspirations of the people involved.

•        Separate from the past: help people let go of the old way without dismissing it, so they can commit to the new one.

•        Create a sense of urgency: clarify why the change cannot wait, without generating panic.

•        Support a strong leader role: identify and mobilize the champions who will drive the change within their teams and networks.

•        Line up political sponsorship: secure the backing and resources needed to make the change legitimate and viable.

•        Craft an implementation plan: align systems, processes, and HR policies with the new expected practices.

•        Develop enabling structures: cultivate the skills, mechanisms, and networks required to support people through the learning curve.

•        Communicate, involve people, and be honest: transparency and active participation are the two most powerful levers for reducing resistance.

•        Reinforce and institutionalize change: ensure the change is successful when it no longer relies on an external push but on the internal culture of the organization.

What Kanter Offers Us Today

Kanter’s unique contribution is putting organizational culture and systemic conditions at the heart of change success. While Lewin clarifies individual and collective psychological dynamics, and Kotter structures operational delivery, Kanter examines the entire ecosystem in which the change occurs. An organization whose evaluation, compensation, and recognition systems align with old behaviors cannot successfully adopt new ones for the long term.

Her emphasis on transparency and participation anticipated the collaborative approaches that form the core of modern change management practices. Her work on organizational barriers also helped build a systemic understanding of resistance, moving far beyond simple individual psychology. 

Lewin, Kotter, and Kanter: How to Use Them Together

These three models do not compete; they complement each other. Each illuminates a different angle of the same process, and combining them offers a more complete, practical vision of what active change management involves.

Lewin provides the fundamental psychological framework: understanding why individuals resist, how a group changes its collective norms, and why stabilization is its own distinct phase. His model is incredibly valuable for analyzing human dynamics and designing tailored support.

Kotter provides the operational roadmap: his eight steps form a practical guide for managers tasked with running a transformation project. His focus on the guiding coalition, the vision, short-term wins, and cultural integration addresses the real-world mistakes that most organizations make.

Kanter brings a systemic perspective: looking beyond individuals and projects to evaluate structures, processes, and organization culture. Her model is particularly helpful for HR teams and leaders who want to develop long-term organizational change capability, rather than just managing one-off projects.

A Concrete Example of Coordination

Let's look at the rollout of a new collaborative work tool. Using Lewin's model, you begin by analyzing current habits and group norms to design an appropriate unfreezing phase. With Kotter, you build a coalition of internal champions, define a clear vision of the future state, and plan visible, early wins. With Kanter, you verify that evaluation systems, management practices, and team culture align with the new expected behaviors, monitoring progress regularly to adjust along the way. 

Are These Models Still Valid Today?

It is a fair question to ask. These models were designed in organizational and technological settings quite different from our own. The change that Lewin, Kotter, and Kanter analyzed was discrete, planned, and bounded in time. Today, organizations experience continuous, simultaneous, and often externally driven transformations.

Three limitations are worth noting. First, these models assume change has an identifiable beginning and end, which is rarely the case in organizations undergoing constant transformation. Second, they were built for environments where you had ample time to guide people: today, project timelines have shrunk significantly. Third, they do not specifically address transformations driven by AI and automation, which impact professional identity in a fundamentally different way than classic reorganizations.

Even so, their core foundations remain completely valid. The human behaviors they describe—such as the attachment to habits, the need for meaning, the value of active participation, the role of leadership, and the power of cultural integration—are human constants. Neither AI nor rapid technology shifts change these truths. What shifts is the pace, intensity, and nature of the transformations. What remains unchanged is how people navigate them.

Change management practitioners use these models as compasses rather than rigid rules. They combine them with agile approaches, design thinking, collaborative facilitation methods, and real-time adoption measurement tools. Theory and practice move forward together. 

FAQ: Frequently Asked Questions on Change Management Models

Which model should I choose between Lewin, Kotter, and Kanter?

There is no single correct answer. Your choice depends on your goal. Lewin is best for understanding human dynamics and designing support initiatives. Kotter is the most practical for structuring a transformation project's execution. Kanter is most relevant for evaluating systemic and cultural conditions. In practice, the most effective initiatives combine all three perspectives.

Why do 70% of change projects fail according to Kotter?

Kotter identifies eight major mistakes that correspond to the eight steps of his model: weak urgency, an ineffective coalition, underestimating a clear vision, under-communicating, allowing barriers to block change, neglecting short-term wins, declaring victory too early, and failing to anchor the change in the culture. Any single one of these errors can derail a project, no matter how well-engineered it is technically.

What is resistance to change in Lewin’s theory?

For Lewin, resistance to change is not a personal issue, but a normal, collective response to a disrupted equilibrium. He conceptualizes this through Force Field Analysis: change results from a balance between driving forces (pushing toward change) and restraining forces (opposing it). To drive change, it is more effective to reduce the restraining forces than to force the driving ones.

Is Kanter still relevant today?

Yes, perhaps more than ever. Kanter’s focus on transparency, active participation, and the alignment of organizational systems resonates deeply today. AI-driven transformations generate profound concerns about the future of work, meaning superficial answers are no longer enough. People need real input into defining their new roles, combined with perfect consistency between leadership messaging, evaluation, and compensation systems.

Are there newer change management models?

Yes. The ADKAR (Prosci) model, developed in the 2000s, offers an individual-focused approach: Awareness, Desire, Knowledge, Ability, Reinforcement. Large organizations use it widely to manage individual change journeys and track adoption progress. Agile change approaches have also emerged, prioritizing short development cycles, experimentation, and learning over rigid linear plans. 

Conclusion: Models as Compasses, Not Recipies

Lewin, Kotter, Kanter: three distinct perspectives on a single challenge—supporting individuals and organizations through transformations that disrupt and require genuine effort. Seventy years after Lewin's first publications, these models remain highly relevant because they focus on what does not change: how human beings experience and adapt to change.

However, these models cannot replace situational intelligence, listening to your teams, and the adaptive capacity of managers and change practitioners. They reveal their full value when you combine them with a clear understanding of your unique context and people.

For those who wish to deepen these approaches and apply them directly, change management training programs help you transition from theory to practical mastery, matching the pace and context of your organization.
