7 Change Management Models Every Leader Should Know

Change management models are structured frameworks that help organizations plan, implement, and sustain transformation. The most widely adopted models include Kurt Lewin's 3-Stage Model, the ADKAR (Awareness, Desire, Knowledge, Ability, Reinforcement) Model, Kotter's 8-Step Model, McKinsey 7-S, and the Kübler-Ross Change Curve. Each addresses a different dimension of change, from individual psychology to organization-wide alignment. Understanding the differences helps leaders choose the right approach for their specific context and reduce employee resistance to change.

"Traditional business strategy too often does not bother to create a story or narrative about its actions for its employees and the world to gather around. For the strategy to become reality, people need to see themselves in the story and then take action to make the story happen."

What Are Change Management Models?

A change management model is a repeatable framework that guides leaders and their teams through organizational shifts, whether those shifts involve new technology, restructuring, process updates, or cultural transformation. These models were developed through observation of real-world organizational behavior and are designed to reduce friction, build employee commitment, and make change outcomes more predictable and sustainable.

No single model fits every situation. The value of understanding multiple frameworks is that you can select the elements most relevant to your organization's size, culture, and the nature of the change itself. The seven models below represent the most cited and applied frameworks in the field today.

1. Lewin's Change Model: Unfreeze, Change, Refreeze

Kurt Lewin's 3-Stage Model is one of the oldest and most widely referenced frameworks in change management. Developed in the 1940s, it remains relevant because of its simplicity and psychological grounding. The model describes change as a three-stage process of unfreezing existing behaviors, transitioning to new ones, and then stabilizing the new state.

The Three Stages

1. Unfreeze: The organization challenges the status quo and builds awareness of why change is necessary. At this stage, people may feel unsettled or resistant as they are asked to question familiar routines.
2. Change (Transition): People begin to adopt new behaviors, processes, or tools. Uncertainty is highest here, and clear communication and leadership support are critical.
3. Refreeze: New behaviors are reinforced, embedded into standard practice, and aligned with organizational culture so that the change is sustainable.

Lewin's model is best suited to organizations that need a clean, linear framework for a well-defined change initiative. Its main limitation is that it treats change as a discrete event rather than a continuous process, which can be a poor fit for organizations in rapid, ongoing transformation.

2. ADKAR Model: Individual-Level Change

The ADKAR model was created by Jeffrey Hiatt, founder of Prosci, based on analysis of hundreds of organizational change projects. The model is explicitly focused on the individual rather than the organization as a whole, on the premise that organizational change only succeeds when each person successfully navigates their own transition.

The Five Elements of ADKAR

• Awareness: The individual understands why the change is necessary.
• Desire: The individual is motivated and willing to support the change.
• Knowledge: The individual knows how to change, including the skills and behaviors required.
• Ability: The individual can apply the knowledge in practice.
• Reinforcement: Mechanisms are in place to sustain the change and prevent regression.

ADKAR is particularly useful as a diagnostic tool. If a change initiative is stalling, the model helps pinpoint exactly where individuals are getting stuck, whether that is lack of awareness, insufficient training (Knowledge), or inadequate follow-through (Reinforcement). This makes it actionable as well as descriptive.

3. McKinsey 7-S Model: Organizational Alignment

The McKinsey 7-S framework was developed by consultants at McKinsey and Company in the late 1970s. Rather than guiding a change process step by step, it provides a diagnostic map of the seven internal elements that must be aligned for an organization to perform effectively. The key insight is that these elements are interdependent: changing one will create ripple effects across all the others.

The Seven Elements

Shared Values sit at the center of the model because they influence and are influenced by all six other elements. The McKinsey 7-S Model is especially valuable during mergers, large-scale restructuring, or digital transformation, where changes to one element (such as Systems) quickly expose misalignments in Staff capabilities or organizational Structure.

4. Kotter's 8-Step Model: Leading Large-Scale Change

Harvard Business School professor John Kotter developed his 8-Step Model of Change after observing more than 100 organizations attempting transformation. The model focuses on the human and leadership dimensions of change rather than the technical process, and it is structured as a sequential roadmap that builds organizational momentum over time.

The Eight Steps

1. Create a sense of urgency: Help people understand why the change is necessary and time-sensitive.
2. Build a guiding coalition: Assemble a cross-functional team of leaders and advocates with the authority and credibility to drive the initiative.
3. Form a strategic vision: Define a clear, compelling picture of where the organization is heading and how it will get there.
4. Communicate the vision: Share the vision consistently and transparently with all stakeholders.
5. Remove obstacles: Identify and address structural, procedural, or cultural barriers that block progress.
6. Generate short-term wins: Create and celebrate visible early successes to build confidence and momentum.
7. Sustain acceleration: Use early wins as a foundation to drive deeper, broader change rather than declaring victory too soon.
8. Anchor change in culture: Reinforce new behaviors and practices until they become embedded in the organization's norms and values.

Kotter's model is well-suited to large, complex organizations where winning hearts and minds is as important as executing a plan. Its emphasis on urgency and coalition-building makes it particularly effective for top-down transformation initiatives.

5. Bridges Transition Model: Managing the Human Journey

Consultant William Bridges developed the Bridges Transition Model to draw a deliberate distinction between change (an external event) and transition (the internal psychological journey people go through in response to that event). The model argues that organizations often manage the change well but fail to manage the transition, which is why so many initiatives lose momentum after launch.

The Three Transition Stages

Ending, and Letting Go
The first stage begins the moment a change is announced. Employees must let go of familiar roles, processes, or identities. This is where resistance is born, and where leaders must acknowledge loss rather than minimize it.

The Neutral Zone
The second stage is a state of limbo where old ways have been left behind but new ways have not yet taken hold. Productivity may dip, confusion is common, and anxiety can rise. Bridges viewed this stage as both the most difficult and the most creative, because it is where genuine reinvention happens.

The New Beginning
The third stage marks the point at which employees genuinely embrace new behaviors, adopt new identities, and commit to the changed organization. This stage requires reinforcement and recognition from leadership to take root.

6. Kübler-Ross Change Curve: Emotional Stages of Change

Psychiatrist Elisabeth Kübler-Ross originally developed her five-stage grief model to describe responses to terminal illness. The model was subsequently adapted by organizational practitioners as the Kübler-Ross Change Curve to describe the emotional journey employees experience during significant workplace disruption. It remains one of the most widely used frameworks for understanding and anticipating emotional resistance to change.

The Five Emotional Stages

• Denial: Employees refuse to accept or minimalize the reality of the change.
• Anger: Frustration surfaces as the change becomes unavoidable.
• Bargaining: Employees attempt to negotiate a way to limit the impact of the change on their work or roles.
• Depression: Motivation and productivity can dip as the full impact of the change settles in.
• Acceptance: Employees begin to engage constructively with the new reality.

A critical insight of the model is that individuals cross these stages at different speeds and may cycle back through earlier stages. Leaders who understand this can provide targeted support, such as more intensive communication for employees still in denial or additional training for those who have reached acceptance but lack confidence. The model reinforces the importance of empathy and transparent dialogue throughout a change initiative.

7. The Deming Cycle: Continuous Improvement

The Deming Wheel, also known as the PDSA (Plan-Do-Study-Act) Cycle, was developed by statistician and management thinker W. Edwards Deming. Unlike the other models on this list, it is not designed to manage a one-time transition. Instead, it is a circular, iterative framework for continuous improvement, making it particularly relevant for organizations that treat change as an ongoing operational discipline rather than a project.

The Four Stages

• Plan: Identify the problem or opportunity, analyze root causes, and design a targeted improvement plan.
• Do: Implement the plan on a small scale or in a pilot environment to test its effectiveness.
• Study: Measure and analyze the results of the pilot against the expected outcomes.
• Act: If the pilot succeeded, roll out the change more broadly and standardize it; if not, revise the plan and begin the cycle again.

The PDSA Cycle's iterative structure makes it well-suited to process improvement, quality management, and technology rollout scenarios where learning and adjustment are expected. Its circular nature also reinforces a culture of continuous learning, where each completed cycle informs the next improvement initiative.

How to Select the Right Change Management Model

There is no universally correct change management model. The right choice depends on the nature and scale of the change, the organizational culture, and the specific challenges you anticipate. In practice, many organizations draw on more than one model simultaneously: for example, using McKinsey 7-S to assess organizational readiness, ADKAR to track individual adoption, and Kotter's framework to structure leadership activities.

Regardless of which model you select, the consensus across all seven frameworks is consistent: place employees at the center of the process, communicate transparently at every stage, and build in mechanisms for reinforcement so that new behaviors stick. Change that does not reach people at an individual level rarely endures at an organizational level.

For organizations navigating digital transformation, change management models work best when supported by tools that help employees build confidence in new systems from day one. Lemon Learning is a digital adoption platform designed to deliver in-application guidance, interactive walkthroughs, and real-time support directly within the tools employees are learning. This approach reinforces the Ability and Reinforcement stages of ADKAR, accelerates the Refreeze stage in Lewin's model, and helps generate the short-term wins that Kotter identifies as critical to sustaining momentum. You can explore how the platform supports digital adoption at an organizational level, or download a practical framework in our change management guide.

Frequently Asked Questions

What are the three change management models?

The three most foundational change management models are Kurt Lewin's 3-Stage Model (Unfreeze, Change, Refreeze), the ADKAR Model, and Kotter's 8-Step Model. These three frameworks are widely cited because they address change from different angles: psychological readiness, individual adoption, and organizational leadership respectively.

What is the 7-S model of change management?

The McKinsey 7-S Model identifies seven interdependent organizational elements that must be aligned for effective change: Strategy, Structure, and Systems (the hard, tangible elements) and Style, Staff, Skills, and Shared Values (the soft, intangible elements). Changing any single element creates a ripple effect across all others.

What are the 5 C's of change management?

The 5 C's of change management are Context, Clarity, Commitment, Communication, and Culture. While not tied to one specific named model, they are frequently used as a practical leadership checklist alongside structured frameworks such as ADKAR or Kotter's 8-Step process to ensure change initiatives are well-communicated and culturally grounded.

What is Kurt Lewin's 3-step model?

Kurt Lewin's 3-Step Model describes change as three sequential stages: Unfreeze (challenging existing behaviors and building awareness), Change or Transition (adopting new processes and behaviors), and Refreeze (stabilizing and embedding the new state into everyday practice). Developed in the 1940s, it remains widely used because of its clarity and ease of application.
