I’ve led or been involved in organizational changes ranging from software migrations to full restructurings. Some went well. Most went worse than expected. And in every case, the problems weren’t technical — they were human.
Change management frameworks exist because humans are predictably irrational about change. We resist it even when we intellectually agree it’s necessary. We mourn what we’re losing even when what we’re gaining is objectively better. We comply behaviorally while resisting emotionally. Understanding these patterns — and having a framework to address them — is the difference between change that sticks and change that collapses the moment leadership looks away.
These eight frameworks represent fundamentally different philosophies about how change works. Some focus on organizational steps. Some focus on individual psychology. Some focus on both. I’ll tell you when each one works best and where each one breaks down.
Key Takeaways
- No single framework works for every type of change — matching the framework to the situation is half the battle
- Step-based models (Kotter, Lewin) work well for planned, top-down changes; psychology-based models (Bridges, Kübler-Ross, Satir) work better when emotional resistance is the primary barrier
- ADKAR is the most practical individual-level framework; McKinsey 7-S is the most comprehensive organizational-level one
- Most change failures aren’t framework failures — they’re commitment failures, where leadership moves on before the change is embedded
1. Kotter’s 8-Step Model
Best for: Large-scale organizational transformations that need executive sponsorship and sustained momentum
John Kotter’s model, published in “Leading Change” (1996), remains the most widely referenced change framework in corporate settings. The eight steps provide a sequential roadmap:
1. Create urgency — build a compelling case for why the status quo is unsustainable
2. Build a guiding coalition — assemble influential leaders who champion the change
3. Form a strategic vision — define what the changed organization looks like
4. Enlist a volunteer army — communicate the vision broadly and recruit supporters
5. Enable action by removing barriers — eliminate structural obstacles to the new behaviors
6. Generate short-term wins — create visible successes early to build momentum
7. Sustain acceleration — use early wins to drive deeper changes
8. Institute change — embed the new approaches into organizational culture
Where it works: Kotter excels when change requires broad organizational buy-in and sustained effort over months or years. The emphasis on urgency and coalition-building addresses the two most common failure points in large changes: complacency and lack of leadership alignment.
Where it breaks down: The model is sequential, but real organizational change is messy and nonlinear. You’ll often find yourself working on steps 3, 5, and 6 simultaneously. It also focuses primarily on leadership and strategy without deeply addressing individual employee psychology. If your people are emotionally resistant, Kotter tells you to “remove barriers” but doesn’t give you tools for the emotional work that requires.
My experience: I’ve used Kotter for two major restructurings. The urgency step is the most important and most often shortchanged. When leaders assume the urgency is obvious, they skip to vision — and then wonder why no one follows.
2. Lewin’s Change Model
Best for: Simple, clearly defined changes where the current state and desired state are both well understood
Kurt Lewin’s model (1947) is the oldest and simplest: Unfreeze, Change, Refreeze.
Unfreeze: Prepare the organization for change by disrupting the current equilibrium. Challenge existing assumptions, present data that creates dissatisfaction with the status quo, and create psychological safety for new behaviors.
Change: Implement the new processes, structures, or behaviors. Provide training, support, and clear communication about what’s expected.
Refreeze: Stabilize the organization around the new normal. Reinforce new behaviors through systems, rewards, and cultural norms until they become automatic.
Where it works: Lewin’s simplicity is its strength. When you’re implementing a well-defined change (new software, new process, new reporting structure), three stages are often all you need. The model’s clarity makes it easy to communicate to everyone involved.
Where it breaks down: The “refreeze” concept assumes you’ll reach a new stable state, which is increasingly unrealistic in environments where change is continuous. Organizations that “refreeze” after every change develop rigidity that makes the next change even harder. Also, the model doesn’t address the emotional dimension of change beyond surface-level acknowledgment.
3. Bridges’ Transition Model
Best for: Changes where emotional resistance is the primary obstacle, not logistical complexity
William Bridges made a critical distinction: change is situational (new software, new structure, new boss), but transition is psychological (how people internally process and adapt to that change). His model focuses entirely on the human experience:
Ending, Losing, Letting Go: Every change begins with an ending. People must let go of the old identity, routines, and relationships before they can embrace anything new. This stage is often ignored by leaders who want to “focus on the positive” and skip straight to the new beginning.
The Neutral Zone: The uncomfortable in-between where the old way no longer applies but the new way hasn’t become natural yet. Productivity drops. Anxiety increases. People feel unmoored. This is where most change initiatives fail, because leaders interpret the discomfort as evidence that the change was wrong, rather than recognizing it as a normal part of transition.
The New Beginning: People develop new identities, competencies, and energy around the changed reality. This can’t be rushed — it emerges when people have genuinely processed the ending and survived the neutral zone.
Where it works: Bridges is invaluable when the change involves identity shifts — role changes, team restructurings, cultural transformations, mergers. Any change where people’s sense of “who I am at work” is disrupted benefits from this framework.
Where it breaks down: It doesn’t provide operational steps for implementing change. It’s a psychological lens, not a project plan. Best used alongside a structural framework like Kotter or ADKAR.
4. The Satir Change Model
Best for: Predicting and managing the emotional performance curve during disruptive changes
Virginia Satir’s model describes five stages that map performance and emotional state during change:
Late Status Quo → Resistance → Chaos → Integration → New Status Quo
The model’s unique contribution is normalizing the “chaos” stage — the productivity valley where performance drops below the original baseline before it improves. This is the point where most organizations panic and either revert the change or double down with pressure, both of which make things worse.
Where it works: The Satir model is excellent for setting realistic expectations. When I show leaders this curve before a change initiative, it prevents the “why is everything getting worse?” panic at month three. Knowing that chaos is a normal, temporary stage changes how leaders respond to it.
Where it breaks down: Like Bridges, it’s descriptive rather than prescriptive. It tells you what will happen emotionally but doesn’t give you detailed steps for managing each stage. It also doesn’t help you decide what to change — only how to anticipate the emotional response.
5. Kübler-Ross Change Curve
Best for: Understanding individual emotional responses to unwelcome or imposed changes
Adapted from Elisabeth Kübler-Ross’s grief model, this framework maps five emotional stages: Denial → Anger → Bargaining → Depression → Acceptance.
In organizational settings, this looks like: “This won’t actually happen” → “This is terrible and unfair” → “Maybe if we do it this way instead” → “I can’t believe this is really happening” → “Okay, this is the new reality.”
Where it works: The Kübler-Ross curve is most useful for empathy-building among leaders. When a manager understands that an angry reaction to change is a predictable stage rather than a personal attack or evidence of a bad attitude, they respond more effectively. It’s also useful for one-on-one conversations with individuals who are struggling.
Where it breaks down: People don’t move through these stages linearly or predictably. Some skip stages, some loop back, some experience multiple stages simultaneously. The model also doesn’t scale well — it’s an individual-level framework applied to groups, which means the team might have people at five different stages simultaneously. And it provides no action steps for moving people through the stages faster.
6. ADKAR Model
Best for: Individual-level change adoption, especially when you need to diagnose where specific people are getting stuck
Prosci’s ADKAR model (Jeffrey Hiatt) is the most actionable individual-level framework. It defines five sequential milestones that every person must reach:
Awareness: Understanding why the change is necessary
Desire: Personal motivation to participate in the change
Knowledge: Understanding how to change (skills, processes, tools)
Ability: Demonstrated capability to implement the change
Reinforcement: Sustained support to maintain the change
The diagnostic power: ADKAR’s greatest strength is pinpointing exactly where an individual is stuck. A person who understands why the change is needed but doesn’t want to participate has an Awareness-to-Desire gap. A person who wants to change but doesn’t know how has a Desire-to-Knowledge gap. Each gap requires a different intervention.
Where it works: ADKAR is practical, measurable, and applicable to any type of change. I’ve used it for technology adoptions, process changes, and cultural shifts. The ability to diagnose individual barriers makes it especially useful for managers having one-on-one conversations.
Where it breaks down: It’s an individual-level model applied person by person, which can be resource-intensive for large-scale changes. It also doesn’t address organizational alignment, structural barriers, or leadership coalition-building. Best paired with an organizational-level framework.
7. McKinsey 7-S Model
Best for: Diagnosing organizational alignment problems and understanding how changes in one area ripple through others
The 7-S framework examines seven interconnected organizational elements: Strategy, Structure, Systems, Shared Values, Style, Staff, and Skills. The core insight is that changing one element without adjusting the others creates misalignment that undermines the change.
Hard elements (easier to change): Strategy, Structure, Systems
Soft elements (harder to change): Shared Values, Style, Staff, Skills
Where it works: McKinsey 7-S excels at diagnosis. When something feels wrong but you can’t articulate why, mapping all seven elements usually reveals the misalignment. A company that changes its strategy to “innovation-first” but keeps its old risk-averse approval systems (Systems) and promotes only safe operators (Staff, Style) will fail. The 7-S model makes that misalignment visible.
Where it breaks down: It’s a diagnostic framework, not a change management process. It tells you what’s misaligned but doesn’t give you a step-by-step approach for fixing it. The seven elements are also broad enough to make the analysis feel overwhelming. I’ve found it works best as a pre-change diagnostic, not an ongoing management tool.
8. Nudge Theory
Best for: Gradual behavior changes that work better through choice architecture than mandates
Based on Richard Thaler and Cass Sunstein’s work, Nudge Theory suggests that you can influence behavior by changing how choices are presented rather than restricting or mandating choices.
Organizational examples: Making the desired behavior the default option (opt-out instead of opt-in for retirement savings). Placing healthy food at eye level in the cafeteria. Making the new software the homepage while keeping the old system accessible. Publicly celebrating teams that adopt the new process.
Where it works: Nudge Theory is powerful for behavioral changes that don’t require dramatic disruption. It respects individual autonomy while gently steering behavior. For gradual cultural shifts, habit changes, and adoption of new tools or processes, nudges often succeed where mandates create resistance.
Where it breaks down: It’s too subtle for urgent or large-scale transformations. If you need to restructure an entire department or migrate to a new system by a hard deadline, nudges won’t create sufficient momentum. It also requires careful design — a poorly designed nudge can backfire or feel manipulative.
How to Choose the Right Framework
Large organizational transformation: Start with Kotter’s 8 Steps for the overall structure. Add ADKAR for individual adoption. Use McKinsey 7-S as a pre-change diagnostic.
Technology or process change: Lewin (Unfreeze-Change-Refreeze) for the overall approach. ADKAR for diagnosing individual adoption barriers.
Emotionally charged change (layoffs, restructuring, mergers): Bridges’ Transition Model to understand and support the human experience. Kübler-Ross for individual conversations. Satir to set leadership expectations about the performance valley.
Gradual cultural shift: Nudge Theory for behavior design. McKinsey 7-S to ensure organizational alignment supports the desired culture.
The honest truth: Most successful change initiatives combine frameworks rather than following one exclusively. The organizational-level models (Kotter, Lewin, McKinsey) provide structure. The individual-level models (ADKAR, Bridges, Kübler-Ross) provide empathy. The behavioral models (Nudge) provide practical tools. Using at least one from each category gives you the best chance of change that actually lasts.
