Lippitt’s change theory is a seven-phase framework for managing planned change in organizations, developed by Ronald Lippitt, Jeannette Watson, and Bruce Westley in 1958. It grew directly out of Kurt Lewin’s earlier three-step model but expanded the process into a more detailed sequence and placed far greater emphasis on the person driving the change, known as the change agent. The theory has had its strongest uptake in healthcare and nursing management, where it continues to guide improvement projects, though its logic applies to any setting where change needs to be deliberate rather than improvised.
Where the Theory Came From
Lewin’s model, published in the late 1940s, described organizational change in three broad strokes: unfreeze existing behavior, move to a new state, and refreeze the new behavior so it sticks. It was elegant but sparse. Lippitt and his colleagues felt that practitioners needed more granularity, especially around how to diagnose problems before acting and how to manage the relationship between the person leading the change and the people experiencing it. Their 1958 book, The Dynamics of Planned Change, broke the process into seven phases and shifted the theoretical center of gravity toward what the change agent actually does at each stage.
That focus on the change agent is what distinguishes Lippitt’s theory from most competing models. Lewin treated the group or organization as the main unit of analysis. Lippitt asked a different question: what does the person responsible for shepherding this change need to think about, decide, and do at each point in time? The answer became a seven-phase sequence that reads less like an abstract model and more like a project plan.
The Seven Phases
Each phase represents a distinct task the change agent should complete before moving to the next. They are sequential in theory, though in practice people often loop back to earlier phases when new information surfaces.
- Phase 1: Diagnose the problem. Before proposing any solution, the change agent gathers data to understand the current situation. What is actually going wrong, and for whom? This phase is about resisting the urge to jump to a fix before the problem is clearly defined.
- Phase 2: Assess motivation and capacity for change. Even a well-diagnosed problem may not lead to successful change if the people involved are not ready for it. This phase examines whether the organization or team has the willingness and the resources to change.
- Phase 3: Assess the change agent’s own motivation and resources. Lippitt was unusual in asking the change agent to turn the lens inward. Do you have the expertise, the time, the credibility, and the emotional stamina to see this through? If not, the project may need a different leader or additional support.
- Phase 4: Select progressive change objectives. This is the planning stage, where specific goals and timelines are set. Rather than aiming for one dramatic overhaul, the model favors incremental objectives that build toward the larger goal.
- Phase 5: Choose an appropriate role for the change agent. The change agent might act as an expert, a facilitator, a coach, or an advocate, depending on the situation. This phase involves picking the role that fits the organizational culture and the specific resistance patterns at play.
- Phase 6: Maintain the change. Once the new practice or behavior is in place, the change agent works to stabilize it so it does not slide back to the old way of doing things.
- Phase 7: Terminate the helping relationship. The change agent gradually withdraws, transferring ownership of the new practice to the people who will sustain it going forward. The goal is that the change survives without the change agent’s ongoing involvement.
The first three phases are diagnostic and reflective. The middle phases are action-oriented. The final two deal with sustainability and exit. That arc from diagnosis through action to handoff is one reason the model appeals to project managers and healthcare leaders: it mirrors how real initiatives unfold when they go well.
The Planning and Execution Phases in Practice
Phases 4 and 5 are where the theory gets most operational. In Phase 4, the change agent develops a concrete plan that accounts for factors like staff skills, cost, and the forces pushing for and against the proposed change. A timetable is drawn up, and each team member gets a defined responsibility. The plan also identifies which broad strategy will guide implementation: you might rely on educating people with evidence, on leveraging authority, or on reshaping group norms and values.
Phase 5 asks the change agent to pick a role and commit to it. The theory treats change agents as active participants, not distant planners. At this stage the agent transforms intentions into concrete efforts, and resistance often intensifies precisely because the change becomes real rather than theoretical. Lippitt’s model explicitly warns that the change agent should reassess resistance at this point, because forces that seemed manageable during planning may grow once implementation begins.1Nursing Management.

Why the Change Agent Matters So Much
In many change models, the leader is assumed to exist but is not examined in much detail. Lippitt made the change agent a variable to be managed, not just a given. Phase 3’s requirement that the agent assess their own resources is a recognition that change fails not only because people resist it but because the person driving it runs out of credibility, energy, or expertise partway through.
The theory also ties outcomes directly to the change agent’s skill. Whether a proposed change ultimately gets adopted or rejected depends on how accurately the problem was diagnosed, how well the solution fits the problem, how much the affected group was involved in the process, and how skilled the change agent is at navigating all of it. When change does fail, Lippitt’s framework encourages the agent to identify the specific restraining factors and, when possible, rediagnose the problem with the new information that failure provides.2ScienceDirect. Planned Change in Nursing: The Theory
This is a pragmatic stance rather than an optimistic one. The theory does not assume that well-planned change always succeeds. It assumes that when change fails, something in the diagnostic or relational process broke down, and that understanding what broke down is more useful than simply trying again with more force.
How It Differs from Lewin and Kotter
Lewin’s unfreeze-change-refreeze model is the conceptual ancestor, and Lippitt never rejected it. Instead, he treated it as a skeleton that needed muscle and skin. The seven phases essentially elaborate what happens inside Lewin’s three stages, with the biggest additions being the explicit assessment of the change agent (Phase 3) and the deliberate termination of the helping relationship (Phase 7). Lewin’s model does not address either of those.
Kotter’s eight-step model, developed decades later in the 1990s, shares some DNA with Lippitt but was designed primarily for large-scale corporate transformation. Kotter emphasizes creating urgency, building coalitions, and communicating a vision. Lippitt’s model is less concerned with organizational politics and more concerned with the diagnostic rigor of the early phases and the interpersonal dynamics between the change agent and the client system. If Kotter’s model reads like a leadership playbook, Lippitt’s reads more like a consulting engagement plan.
Another key difference: Lippitt’s Phase 7, the termination phase, has no direct equivalent in either Lewin or Kotter. It reflects the model’s roots in consulting and helping relationships, where the goal is always to make the client self-sufficient rather than dependent on the helper. In healthcare settings, where external consultants or project leaders often drive change initiatives with a defined end date, this phase resonates strongly.
Applications in Healthcare and Nursing
Lippitt’s theory has found its most durable home in nursing and healthcare management. The model’s emphasis on diagnosis, on understanding resistance, and on working within a defined relationship between helper and client maps well onto how quality-improvement projects work in clinical settings. A nurse manager introducing a new protocol, for instance, fits naturally into the change agent role, and the nursing staff experiencing the change are the client system.
One concrete example: Lippitt’s framework was used to structure a project aimed at reducing medication errors by cutting down on phone-call interruptions during medication administration. The seven phases provided a step-by-step guide for diagnosing the interruption problem, planning the intervention, implementing it, and handing off the new workflow to the unit’s permanent staff.3USF Scholarship. Reducing Avoidable Interruptions During the Medication Administration Process
Projects like this illustrate why the model persists in healthcare even though it is over six decades old. Medication safety initiatives, infection-control improvements, and workflow redesigns all tend to follow a predictable arc: someone identifies a problem, gathers data, proposes a fix, encounters resistance, implements the change, and then needs it to stick after the project leader moves on. Lippitt’s seven phases match that arc without requiring the user to adopt a lot of abstract organizational theory.
If the change is adopted, the model’s guidance is to focus energy on maintaining or modifying the new practice so it lasts. If it is rejected, the guidance is to identify the restraining factors and, where possible, rediagnose the problem with whatever new information the failed attempt generated.4ScienceDirect. Planned Change in Nursing: The Theory That iterative quality makes it practical for clinical settings where first attempts at change often run into unexpected obstacles.
Strengths of the Model
The model’s greatest strength is probably its clarity. Seven phases, each with a defined purpose, presented in a logical order. For someone who has never led a change initiative before, it provides a scaffold that prevents the most common mistakes: jumping to a solution before understanding the problem, ignoring whether people are ready for change, and walking away before the new practice is stabilized.
The diagnostic emphasis of the first three phases is particularly valuable. Many failed change efforts in organizations can be traced back to a poorly understood problem or a solution that was imposed without assessing readiness. Lippitt’s model forces the change agent to slow down and gather information before acting, which is counterintuitive in environments where leaders are rewarded for speed and decisiveness.
Phase 7, the termination of the helping relationship, is another underappreciated strength. In practice, many change initiatives collapse after the person driving them leaves or shifts attention elsewhere. By making the handoff a formal phase rather than an afterthought, the model increases the odds that the change survives the change agent’s departure. This is especially relevant in consulting engagements, rotating leadership roles, and academic medical centers where improvement projects often have a defined lifespan.
Limitations and Common Criticisms
The most frequent criticism of Lippitt’s theory is that it assumes change can be planned and managed in a linear sequence. Real organizations are messy. Resistance does not wait politely for Phase 5 to surface. New problems emerge mid-implementation that send the team back to Phase 1. The seven-phase structure can feel artificially tidy when applied to a complex, politically charged environment.
The model also gives relatively little attention to organizational culture, power structures, and the systemic forces that shape how change unfolds. It zooms in on the change agent and the client system as a dyad but does not say much about how to handle competing stakeholders, institutional inertia, or the informal networks that determine whether a new practice actually gets adopted on the ground. More recent models, including those that draw on complexity theory, address these dynamics more explicitly.
Another limitation is scope. Lippitt’s model was designed for planned, deliberate change, where someone has identified a specific problem and is proposing a specific solution. It is less useful for emergent change, where the organization needs to adapt to rapidly shifting conditions without a clear endpoint. In a crisis or a fast-moving industry, the luxury of seven sequential diagnostic and planning phases may not exist.
Finally, the model’s emphasis on the individual change agent can be a double-edged sword. It provides clear accountability but can also create a single point of failure. If the change agent lacks skill, loses credibility, or burns out, the entire initiative stalls. Distributed leadership models, where change responsibility is shared across a team rather than concentrated in one person, may be more resilient in some contexts.
Choosing the Right Change Strategy Within the Model
One practical detail that often gets overlooked in summaries of Lippitt’s theory is the role of change strategies within Phase 4. The model recognizes three broad approaches the change agent can choose from when planning implementation. The first relies on presenting evidence and rational argument to persuade people that the change makes sense. The second uses authority and policy to compel compliance. The third works by shifting group norms and values so that people internalize the change rather than merely complying with it.5Nursing Management. Selecting the best theory to implement planned change
Each strategy fits different situations. An evidence-based approach works well when the people affected are professionals who respond to data and logic. An authority-driven approach may be necessary when patient safety is at stake and there is no time for consensus-building. A norm-shifting approach is slower but tends to produce more durable change, because people adopt the new behavior as part of their identity rather than as an external requirement they follow grudgingly.
Experienced change agents often blend these strategies, leading with evidence, backing it up with policy when needed, and working to shift norms over time. The model does not prescribe one strategy as superior; it asks the change agent to make a deliberate choice based on the situation rather than defaulting to whatever feels comfortable.
Using the Model Outside Healthcare
Although nursing and healthcare management account for most of the published applications, Lippitt’s theory is not inherently a healthcare model. Its logic applies wherever a defined change agent is working with a client system to move from a current state to a desired one. Education administrators introducing new curricula, IT departments rolling out new systems, and nonprofit leaders restructuring programs all face the same basic sequence of problems: diagnosing the need, assessing readiness, planning the intervention, managing resistance, and sustaining the result.
The model tends to work best in settings where the change is bounded and the change agent has a clear relationship with the people affected. A department-level workflow improvement, a new training program, a policy revision within a single unit: these are the model’s sweet spot. Organization-wide transformations that involve multiple layers of leadership, competing priorities, and ambiguous accountability may benefit from a model that accounts for more structural complexity.
That said, even in large-scale efforts, individual project teams often find Lippitt’s seven phases useful as a local framework. The team leading one piece of a broader transformation can use the model to manage its own slice of the work, even if the overall initiative is guided by a different strategic framework at the enterprise level. Treating the seven phases as a project-management tool rather than an organization-wide theory of change may be where the model delivers its most consistent value.
