What Is Lewin's Change Model?
Key Takeaways
- ✓Lewin's Change Model describes organizational change as three sequential phases: Unfreeze (preparing people for change), Change (implementing the transition), and Refreeze (stabilizing the new state as the norm).
- ✓Developed by Kurt Lewin in 1947, it's the oldest formal change management framework and the theoretical foundation that later models like Kotter's and ADKAR were built upon.
- ✓The model's core insight is that human behavior is in a state of quasi-equilibrium. To change behavior, you must first disrupt the forces keeping it in place (unfreeze), then introduce new behavior, and finally establish new equilibrium (refreeze).
- ✓73% of change management practitioners still reference Lewin's model as foundational to their practice (ACMP, 2023).
- ✓The force field analysis tool, also created by Lewin, is commonly paired with this model to identify driving and restraining forces before starting a change initiative.
Lewin's Change Model breaks organizational change into three phases: Unfreeze, Change, and Refreeze. Kurt Lewin, a German-American social psychologist, published the framework in 1947 after studying group dynamics and behavioral patterns. His core idea was simple but profound: human behavior isn't random. It's held in place by a balance of forces. Some forces push toward change (dissatisfaction, external pressure, new opportunities). Other forces resist change (comfort, fear, habit, power structures). Lewin called this balance a "quasi-stationary equilibrium." To change behavior, you have to disrupt that equilibrium first. That's the Unfreeze phase. Then you introduce and support new behaviors during the Change phase. Finally, you stabilize the new behaviors so they become the default during the Refreeze phase. For HR professionals, Lewin's model is valuable because it explains why people resist change at a fundamental level. They're not being difficult. They're in equilibrium. And disrupting equilibrium is uncomfortable. Every time you roll out a new HRIS, restructure a department, or change a performance review process, you're asking people to unfreeze behaviors they've practiced for years. Understanding this makes you better at planning transitions that actually work.
What Are the Three Phases of Lewin's Model?
Each phase serves a distinct purpose. Spending too little time on any one of them is the primary reason change efforts fail under this framework.
Phase 1: Unfreeze
Unfreezing is about creating the conditions where change becomes possible. People need to understand why the current state is no longer acceptable before they'll consider alternatives. This phase involves three activities: disconfirmation (presenting evidence that challenges the status quo), creation of survival anxiety (showing what will happen if nothing changes), and creation of psychological safety (reassuring people that the transition won't destroy them). An HR example: before rolling out a new applicant tracking system, the HR team shares data showing that 30% of candidates drop off because the current process is too slow, that competitors using modern ATS platforms are winning talent the company wants, and that the new system will come with training, support, and a 90-day learning period. Lewin warned that moving to the Change phase before adequately unfreezing is the most common and damaging mistake. If people haven't accepted that the old way is broken, they'll fight the new way at every turn.
Phase 2: Change (Transition)
This is the messiest phase. Old behaviors have been disrupted, but new ones haven't solidified yet. People feel uncertain, confused, and often less productive than before. Lewin recognized that this discomfort is normal and necessary. During this phase, people learn new behaviors through education, training, coaching, and practice. They experiment with new processes, make mistakes, and gradually build competence. The role of leadership and HR during this phase is to provide support: clear direction on what's expected, resources for learning, patience with the learning curve, and active coaching. Communication must increase dramatically during the Change phase. People need frequent updates on progress, honest acknowledgment of difficulties, and visible evidence that leadership remains committed. This isn't the time to go quiet. Silence during transition gets interpreted as abandonment.
Phase 3: Refreeze
Refreezing establishes the new behaviors as the standard. It's not enough for people to adopt new practices temporarily. The new way of working must become "just how things are done here." Refreezing activities include: embedding new processes in policies and procedures, updating performance metrics to reflect new expectations, recognizing and rewarding people who exemplify the new behavior, removing access to old systems and processes (making reversal difficult), and hiring and onboarding new employees into the changed environment. Without refreezing, organizations experience what Lewin called "regression to the mean," people gradually drift back to old habits because the new ones aren't anchored. HR teams see this constantly: a company launches a new performance review process, managers use it for one cycle, and then quietly revert to the old approach because nobody enforced the change.
What Is Lewin's Force Field Analysis?
Force field analysis is Lewin's complementary diagnostic tool. It maps the forces pushing for change against those resisting it, giving you a clear picture of what you're working with before you start.
How force field analysis works
Draw a line down the center of a page. On the left, list all forces driving the change (customer complaints, competitive pressure, cost savings, employee feedback, regulatory requirements). On the right, list all forces resisting it (fear of job loss, comfort with current process, lack of skills, political interests, budget constraints). Rate each force's strength on a 1-to-5 scale. The analysis reveals whether driving forces outweigh restraining forces and, more importantly, which specific forces you need to address. Lewin's key insight: it's often easier and less disruptive to reduce restraining forces than to increase driving forces. Adding more pressure for change when people are already anxious tends to increase resistance. Removing obstacles and addressing fears tends to lower resistance naturally.
Force field analysis example for HR
An HR team wants to implement a four-day workweek pilot. Driving forces (rated 1-5): employee demand (5), retention data showing competitors offer flexibility (4), productivity research supporting compressed schedules (3), CEO interest (4). Restraining forces: client expectations of five-day availability (5), middle manager concerns about team coverage (4), IT systems built around five-day schedules (2), "we've always worked five days" mindset (3). Total driving: 16. Total restraining: 14. The analysis shows the change is feasible but fragile. The biggest restraining force (client expectations) needs a specific mitigation plan. Reducing that one force from 5 to 3 (by implementing rotating coverage schedules) would shift the balance decisively.
| Force Type | Examples | How to Address |
|---|---|---|
| Driving (increase) | Market competition, employee dissatisfaction, cost pressure, leadership mandate, regulatory change | Present data publicly, create urgency communications, benchmark against competitors |
| Restraining (decrease) | Fear of unknown, lack of skills, political resistance, comfort with status quo, resource constraints | Provide training, address fears directly, involve resistors in planning, allocate budget |
| Neutral (convert) | Ambivalent stakeholders, fence-sitters, uninformed groups | Share information, invite participation, provide early wins to build confidence |
How Does Lewin's Model Apply to HR Initiatives?
The model's simplicity makes it easy to apply across virtually any HR change scenario.
Restructuring and layoffs
Unfreeze: share financial data and market analysis that makes the restructure necessary. Be transparent about what's driving the decision. Change: provide severance packages, outplacement support, role clarity for remaining employees, and frequent communication about what's changing and what's staying. Refreeze: update org charts, redefine roles and responsibilities, adjust workloads to reflect the smaller team, and establish new team norms. The refreeze phase is often forgotten after layoffs. Remaining employees need new equilibrium, or they'll exist in a permanent state of anxiety and disengagement.
Remote-to-hybrid transition
Unfreeze: present collaboration data showing what's been lost in fully remote work (mentorship gaps, cross-team innovation, new hire onboarding challenges). Change: establish hybrid schedules, redesign offices for collaboration rather than individual work, train managers on hybrid team leadership, and set up technology for seamless remote-office meetings. Refreeze: embed hybrid expectations in offer letters, update the employee handbook, tie office presence to collaboration outcomes (not attendance tracking), and recognize teams that use in-office time well.
Compensation philosophy overhaul
Unfreeze: show that the current comp structure is causing turnover in critical roles, that pay equity gaps exist, or that competitors are winning talent with different approaches (like pay transparency or skills-based pay). Change: design the new comp framework, train managers on the new philosophy, adjust individual pay where needed, and communicate changes to all employees. Refreeze: update all job postings with new pay ranges, embed the new philosophy in annual comp review processes, and publish pay equity reports quarterly. The refreeze here matters enormously: if the old informal negotiation culture persists alongside the new formal framework, pay equity will erode within a year.
Lewin's Model Compared to Kotter and ADKAR
Lewin's framework is foundational. Later models built on his concepts and added more detail.
| Dimension | Lewin's Change Model | Kotter's 8-Step Model | ADKAR (Prosci) |
|---|---|---|---|
| Year created | 1947 | 1996 | 1998 |
| Phases/steps | 3 phases | 8 steps | 5 elements |
| Level of focus | Group dynamics and organizational behavior | Organizational leadership and strategy | Individual adoption and mindset |
| Diagnostic tool | Force field analysis | None built-in | ADKAR assessment (1-5 scoring) |
| Best for | Understanding why people resist change | Planning and executing large-scale transformation | Diagnosing and supporting individual adoption |
| Weakness | Too simple for complex, multi-phase changes | Too linear; doesn't address individual resistance | Doesn't address organizational politics or power |
| Mapping | Unfreeze / Change / Refreeze | Steps 1-4 / Steps 5-7 / Step 8 | Awareness-Desire / Knowledge-Ability / Reinforcement |
What Are the Criticisms of Lewin's Model?
Despite its longevity, Lewin's model faces valid criticisms. Understanding these helps you apply it more carefully.
The 'refreeze' problem in continuous change
The biggest criticism is that modern organizations don't have time to refreeze. Change is constant. By the time you've stabilized one change, the next one is already starting. Critics argue that the refreeze concept implies a static endpoint that doesn't exist in today's business environment. However, defenders of Lewin point out that refreezing doesn't mean permanent rigidity. It means establishing enough stability for people to function effectively before the next disruption. Even in rapidly changing organizations, people need periods of stability to process, adapt, and perform.
Oversimplification
Three phases can't capture the complexity of a multi-year, multi-geography transformation involving thousands of people. That's a fair criticism. Lewin's model works best as a mental framework ("where are we in the change process?") rather than a detailed project plan. For detailed planning, pair it with Kotter's steps or Prosci's ADKAR methodology. Use Lewin's language to explain the big picture to senior leaders and employees. Use more detailed frameworks for execution.
Limited practical guidance
Lewin tells you what needs to happen (unfreeze, change, refreeze) but doesn't give you step-by-step instructions for how to do it. This is why practitioners almost always combine Lewin with other frameworks. ADKAR tells you how to unfreeze individuals (build Awareness and Desire). Kotter tells you how to unfreeze organizations (create urgency, build coalitions). Lewin gives you the conceptual map. The other models give you the driving directions.

How Has Lewin's Model Been Updated for Modern Use?
Scholars and practitioners have adapted Lewin's original concepts to fit contemporary organizational realities.
Schein's elaboration
Edgar Schein, a student of Lewin, expanded the Unfreeze phase into three sub-processes: disconfirmation (realizing the current state isn't working), survival anxiety (understanding the cost of not changing), and psychological safety (believing you can learn the new way without losing face or status). Schein's work made the Unfreeze phase more actionable by giving practitioners specific psychological conditions to create before attempting change.
Continuous change models
Some modern adaptations replace "Refreeze" with "Continuous learning" or "Dynamic stability," acknowledging that organizations rarely reach a true frozen state. These adaptations maintain Lewin's core insight (you must prepare people before changing and stabilize after) while removing the implication that change has a definitive end. The result is a cycle rather than a line: Unfreeze, Change, Stabilize, then Unfreeze again for the next initiative.
