A Practitioner’s Guide to the Most Important Frameworks

by Braden Kelley and Art Inteligencia

Change management models exist because organizational change fails far more often than it succeeds. Research consistently puts the failure rate of major change initiatives at 60–70% — not because leaders lack intelligence or commitment, but because most organizations attempt change without a structured framework for thinking about what change actually requires of people, processes, and leadership.

After two decades of working with organizations on change and innovation, and developing the Human-Centered Change™ methodology — including the Change Planning Canvas™ and more than 70 visual, collaborative tools that make up the Change Planning Toolkit™ — I’ve come to believe that the right change management model is not the one that is most academically respected or most commonly cited. It’s the one that fits your organization’s specific situation, culture, and change challenge.

This guide covers the most important change management models in use today, what each one does well, where each one falls short, and how to choose the right framework for your change initiative.

What is a Change Management Model?

A change management model is a structured framework that helps leaders plan, implement, and sustain organizational change. Models provide a common language for talking about change, a sequence of steps or activities to follow, and a set of principles that reflect how people and organizations actually respond to change. Without a model, change programs tend to focus on technical deliverables (new systems, new org charts, new processes) while neglecting the human dimensions that determine whether change is actually adopted.

The best change management models share three characteristics: they are grounded in how people actually experience change (not just how organizations want them to), they provide actionable guidance rather than abstract principles, and they are flexible enough to be adapted to different organizational contexts and change types.

The Most Important Change Management Models

Lewin’s Change Model (Unfreeze-Change-Refreeze)

Developed by social psychologist Kurt Lewin in the 1940s, this is the foundational model that most others build on. Lewin proposed that change occurs in three stages:

• Unfreeze — Create the motivation and readiness to change by challenging the status quo, communicating the need for change, and reducing the forces that resist it
• Change — Move toward the new desired state through new behaviors, processes, and ways of thinking
• Refreeze — Stabilize and sustain the new state by embedding new behaviors in culture, systems, and practices

Strengths: Elegantly simple. Captures the essential insight that change requires deliberate unfreezing of current patterns before new ones can take hold — an insight most organizations ignore by jumping straight to implementation.

Limitations: Too linear for complex modern change environments. The “refreeze” concept is increasingly obsolete in organizations that need to change continuously rather than stabilize between change cycles. Also provides little practical guidance on how to execute each stage.

Best for: Providing a conceptual foundation and common language for thinking about change. Less useful as a practical implementation guide.

Kotter’s 8-Step Change Model

Harvard Business School professor John Kotter developed his 8-step model based on research into why change programs fail. The eight steps are: create urgency, build a guiding coalition, form a strategic vision, communicate the vision, remove obstacles, generate short-term wins, sustain acceleration, and institute change.

Strengths: The most widely used change management model in large organizations. Strong emphasis on building a coalition of change champions and creating visible short-term wins to sustain momentum. The urgency-first approach addresses one of the most common failure modes in change programs.

Limitations: Primarily a leadership model — it tells leaders what to do but provides little guidance on the employee experience of change. Sequential step approach can create rigidity in dynamic environments. Does not adequately address resistance or the emotional dimensions of change. Works better for top-down, well-resourced change programs in large organizations than for the complex, multi-directional change challenges most organizations actually face.

Best for: Large-scale organizational transformation programs with strong executive sponsorship. Less effective for culture change or change initiatives that require significant employee participation in the design process.

ADKAR Model (Prosci)

Developed by Jeff Hiatt at Prosci, ADKAR focuses on the individual experience of change rather than the organizational process. The acronym stands for Awareness (of the need for change), Desire (to support the change), Knowledge (of how to change), Ability (to implement new skills and behaviors), and Reinforcement (to sustain the change).

Strengths: The best model available for diagnosing where individual change adoption is breaking down. Highly practical — if someone isn’t changing, ADKAR helps you identify exactly which building block is missing. Strong focus on the human side of change that Kotter’s model underemphasizes. Excellent for managing large-scale ERP implementations, technology rollouts, and process changes where individual adoption is the critical success factor.

Limitations: Individual-focused model that doesn’t address organizational or systemic dimensions of change. Can create a mechanical, compliance-oriented approach to change if not applied thoughtfully. Doesn’t address the cultural and leadership behavioral changes required for transformation. The reinforcement stage is often underfunded and underexecuted in practice.

Best for: Technology adoption, process change, and any initiative where the primary challenge is getting individuals to change their behavior in specific, defined ways.

McKinsey 7-S Framework

Developed by Tom Peters and Robert Waterman at McKinsey in the late 1970s, the 7-S Framework identifies seven interdependent elements of an organization: Strategy, Structure, Systems, Staff, Style, Skills, and Shared Values. The model proposes that effective change requires alignment across all seven elements.

Strengths: The most comprehensive organizational diagnostic tool of the major models. Excellent for identifying where misalignment is undermining change efforts — especially useful for post-merger integration, where organizational systems and values are often deeply misaligned. Forces leaders to think systemically rather than focusing on one or two visible elements of change.

Limitations: A diagnostic model, not an implementation guide. Tells you what needs to be aligned but not how to align it. Complex enough that it often requires external facilitation to apply effectively. Can become an academic exercise without strong executive engagement.

Best for: Organizational diagnosis, post-merger integration, and large-scale transformation programs where systemic alignment is the primary challenge.

Bridges’ Transition Model

William Bridges distinguished between change (the external event or situation) and transition (the internal psychological process people go through in response to change). His model identifies three phases: Endings (letting go of the old), the Neutral Zone (the in-between state of confusion and possibility), and New Beginnings (embracing the new).

Strengths: The most psychologically sophisticated of the major models. The critical insight — that transition begins with an ending, not a beginning — is consistently underappreciated by change leaders who focus on communicating the new state without acknowledging the loss of the old one. Exceptionally useful for understanding and managing resistance to change.

Limitations: A conceptual model rather than a practical implementation framework. Requires skilled facilitation to apply effectively. Less useful for organizations looking for a step-by-step change management process.

Best for: Culture change, leadership transitions, post-restructuring integration, and any change situation where resistance and emotional response are the primary obstacles.

Kübler-Ross Change Curve

Originally developed to describe the emotional stages of grief, Elisabeth Kübler-Ross’s model was adapted for organizational change to describe the emotional journey individuals experience when facing unwanted change: shock, denial, anger, bargaining, depression, acceptance, and integration.

Strengths: Helps leaders understand that resistance and emotional responses to change are normal, predictable, and temporary — not signs of failure. Creates empathy for the human experience of change. Particularly useful for communicating with leaders who are frustrated by employee resistance.

Limitations: Originally developed for grief, not organizational change — the mapping is imperfect. Implies a linear progression through stages that people actually experience non-linearly and idiosyncratically. Can inadvertently normalize a passive, wait-it-out approach to change resistance rather than proactive engagement.

Best for: Building change leadership empathy and designing communication strategies that acknowledge the emotional journey of change.

The ACMP Standard for Change Management

Before covering the Human-Centered Change™ methodology, it’s worth acknowledging the ACMP Standard for Change Management — the professional standard developed by the Association of Change Management Professionals (ACMP). The ACMP Standard is not a prescriptive model but a competency framework that defines what effective change management practice looks like across five process groups: Evaluating Change Impact and Organizational Readiness, Formulating the Change Management Strategy, Developing the Change Management Plan, Executing the Change Management Plan, and Closing the Change Management Effort.

The ACMP Standard is significant because it represents the profession’s consensus on what change management involves — independent of any proprietary model or methodology. Practitioners who hold the Certified Change Management Professional (CCMP™) designation are assessed against this standard. The Human-Centered Change™ methodology is designed to be fully consistent with the ACMP Standard, giving practitioners a practical visual toolkit that aligns with the professional framework their organizations may require.

The Human-Centered Change™ Methodology — A Practitioner’s Evolution

Every model above has genuine value. But after years of applying them in organizations and observing where they fell short, I wrote Charting Change and developed the Human-Centered Change™ methodology to address the gaps that no single existing model fills.

The core problem with most change management models is that they are either too abstract (Lewin, Bridges) or too prescriptive (Kotter), too individually focused (ADKAR) or too organizationally focused (McKinsey 7-S), and critically — none of them are visual or collaborative. They were designed to be communicated to people, not built with them. In an era of complex, multi-stakeholder change, that is a fundamental limitation.

The Human-Centered Change™ methodology takes a different approach. At its center is the Change Planning Canvas™ — a poster-sized visual planning tool that functions as the anchor of a physical or digital Change Planning Wall. Surrounding the Canvas are 70 additional tools from the Change Planning Toolkit™, printed at 11″ x 17″ (A3) size, that cover every dimension of change planning: stakeholder mapping, resistance analysis, communication planning, readiness assessment, and more.

The entire toolkit is designed for both physical and digital use. Change teams can build a Change Planning Wall in a conference room using printed tools, or work entirely in online whiteboarding platforms such as Miro, Mural, FigJam, Lucidspark, Google Jamboard, or Microsoft Whiteboard. This flexibility means the methodology works equally well for co-located, hybrid, and fully distributed teams.

The Change Planning Canvas™ and elements of the Change Planning Toolkit™ (26 of 70+) are included with every copy of Charting Change. Commercial licenses for organizational use are available at bradenkelley.com. The methodology is also delivered through workshops, masterclasses, and private events for organizations that want facilitated implementation support.

The result is a change planning approach that is more visual, more collaborative, more comprehensive, and more likely to produce change plans that are genuinely owned by the teams executing them — rather than documents developed by consultants and communicated downward.

How to Choose the Right Change Management Model

No single model is right for every change situation. The most effective change leaders are fluent in multiple models and know when to apply which one. Here is a practical guide:

Your primary challenge	Best model(s) to use
Building executive alignment and urgency for a large transformation	Kotter’s 8-Step Model
Diagnosing why individuals aren’t adopting a new system or process	ADKAR
Understanding and managing emotional resistance to change	Bridges’ Transition Model, Kübler-Ross Change Curve
Identifying systemic misalignment blocking change	McKinsey 7-S Framework
Building a shared, comprehensive change plan with your team	Human-Centered Change™ / Change Planning Canvas™
Post-merger integration or cultural transformation	McKinsey 7-S + Bridges’ Transition Model
Technology rollout or process change	ADKAR + Human-Centered Change™ toolkit
Large-scale organizational transformation	Kotter + Human-Centered Change™ toolkit
Aligning with professional change management standards	ACMP Standard for Change Management + Human-Centered Change™

The most common mistake change leaders make is selecting a model based on familiarity or organizational convention rather than fit. If your organization has always used Kotter, that doesn’t mean Kotter is right for your current change challenge. Take the time to diagnose what your specific situation requires before selecting your framework.
