Most organizational changes fail not because the strategy is wrong, but because the people affected by the change aren’t brought along effectively. The Prosci change management model exists to solve exactly that problem, giving leaders a structured, repeatable framework for managing the human side of transitions. Whether you’re rolling out new technology, restructuring teams after a merger, or shifting company culture entirely, Prosci’s methodology provides the tools to move people from resistance to commitment.
At Robyn Benincasa’s core, our work centers on helping organizations build the kind of team cohesion and leadership resilience that makes change stick. Through decades of experience in adventure racing and firefighting, environments where adapting to change isn’t optional, Robyn has seen firsthand that no framework succeeds without people who trust each other enough to move through uncertainty together. That’s where models like Prosci become powerful: they give structure to the messy, emotional reality of organizational transformation.
This guide breaks down everything you need to understand about the Prosci methodology, including its foundational ADKAR model (Awareness, Desire, Knowledge, Ability, Reinforcement), the Prosci 3-Phase Process, and the PCT Model that ties it all together. You’ll walk away with a clear picture of how each component works, how they connect, and how to apply them when your organization faces its next big shift. If you’re responsible for leading people through change, not just planning it on a whiteboard, this is the operational playbook worth understanding.
What the Prosci change management model is
Prosci is a research-based change management methodology developed by the firm of the same name, founded in 1994. The framework is built on the premise that changes succeed or fail based on individual adoption, not on the quality of the technical solution. While most project management approaches focus on deliverables, timelines, and budgets, Prosci specifically addresses the human dimension: whether the people who need to change their behavior actually do. The model gives practitioners a structured approach to managing change that complements existing project management work without replacing it.
Where Prosci comes from
The Prosci methodology grew out of benchmarking research that began in the late 1990s, with the organization studying hundreds of projects across industries to identify what separated successful change initiatives from failed ones. That research produced a consistent finding: the organizations that managed change well treated it as a deliberate discipline, not an afterthought. Over time, Prosci synthesized those findings into the tools and models practitioners use today, including ADKAR, the PCT Model, and the 3-Phase Process. The methodology has since been applied in over 80 countries and across every major industry sector, which gives it a broad evidence base that most competing frameworks lack.
The core insight behind Prosci is that every organizational change ultimately comes down to individual people deciding to do something differently, and that transition needs to be actively supported.
The three core components of the framework
The Prosci change management model is built on three interlocking components, each of which addresses a different level of the change challenge. Understanding how they relate to each other is the starting point for using the framework effectively.
- ADKAR Model: A goal-oriented model that describes the five outcomes an individual needs to achieve for a change to succeed: Awareness, Desire, Knowledge, Ability, and Reinforcement. ADKAR operates at the individual level.
- PCT Model (Project Change Triangle): A diagnostic tool that assesses the overall health of a change initiative by examining three dimensions: Leadership/Sponsorship, Project Management, and Change Management. It operates at the project level.
- Prosci 3-Phase Process: A structured process that guides change practitioners through Preparing for Change, Managing Change, and Reinforcing Change. It connects individual and project-level work into a coordinated sequence.
Each component works independently, but they’re designed to function as a connected system. You can use ADKAR to diagnose where an individual is stuck, use the PCT Model to assess whether your initiative has the right conditions to succeed, and use the 3-Phase Process to sequence your actual change management activities in a logical order.
Why the individual-level focus changes everything
Most change frameworks operate at the organizational or process level. They produce communication plans, training schedules, and stakeholder maps, all of which are useful. But Prosci specifically focuses on the individual because organizations don’t change; people do. A new system only delivers value if the people operating it actually use it correctly. A restructured team only performs better if the members adjust their behavior. Prosci’s emphasis on individual outcomes means that every tool in the framework ultimately points back to one question: what does this specific person need to move forward?
This individual focus also makes Prosci highly actionable for managers and team leads, not just change management specialists. When you understand ADKAR, you can have a targeted conversation with a resistant employee and diagnose exactly where they’re stuck in the change process. That’s a practical capability that most leadership frameworks don’t provide, and it’s what makes Prosci useful beyond the walls of a dedicated change management office.
Why this model matters for real adoption
Most organizations invest heavily in the technical side of change: new software licenses, process redesign, rebranding, restructuring plans. What they routinely underinvest in is the human side, specifically the work of helping individuals understand why the change is happening, want to participate in it, and actually sustain new behaviors over time. The prosci change management model exists precisely to fill that gap with a structured approach that is measurable, repeatable, and grounded in research rather than intuition.
The gap between launching a change and embedding it
Launching a change is relatively easy. You announce the initiative, roll out training, update the org chart, and move on. Embedding the change, meaning getting people to actually work differently six months later, is where most initiatives break down. Research from Prosci’s benchmarking studies consistently shows that projects with excellent change management are significantly more likely to meet their objectives, stay on schedule, and come in on budget compared to projects with poor or no change management. That gap exists because unmanaged resistance, confusion, and skill deficits don’t disappear on their own; they accumulate until the initiative quietly stalls.
When people lack awareness of why a change is necessary, no amount of training or process documentation will move them forward.
Why a framework beats ad hoc effort
Without a structured model, change management becomes a collection of well-intentioned activities with no coherent logic connecting them. You might send a few emails, run a town hall, and designate someone as a "change champion" without any clear theory of what outcome each activity is supposed to produce. A structured framework forces you to ask the right questions in the right sequence: Do people know the change is coming? Do they want to support it? Do they have the skills to execute it?
That sequencing matters more than most leaders realize. Investing in detailed training before people understand why the change is necessary produces low retention and high frustration. Prosci’s framework builds in a deliberate order of operations, so your investments in communication, coaching, and training land at the moments when individuals are actually ready to receive them. The result is not just a smoother rollout, but a fundamentally better chance that the change you worked hard to design actually shows up in day-to-day behavior, where it creates real organizational value.
ADKAR explained: the five outcomes
ADKAR is the foundational model within the prosci change management model, and it describes the five specific outcomes that any individual must achieve for a change to take hold in their behavior. The model works sequentially: each element builds on the one before it, so a gap at any stage blocks progress at every stage that follows. Understanding ADKAR shifts how you approach conversations with your team because instead of guessing why someone is resistant, you can diagnose exactly where they are in the process.
ADKAR’s sequential logic is its most important feature: you cannot train your way out of a Desire problem, and you cannot coach your way out of a Knowledge gap.
Awareness and Desire: the motivational foundation
Awareness is the first outcome, and it answers one question: does this person understand why the change is necessary? Without a clear reason for the change, nothing else works. People need to know what is driving the initiative and what happens if the organization does not act. Awareness is not a memo or a single all-hands meeting. It requires ongoing communication through trusted channels, particularly direct managers, who carry far more credibility with employees than executive announcements alone.
Desire is the second outcome, and it is often the hardest to build. Awareness tells people why the change is happening; Desire determines whether they actually choose to support and participate in it. Desire is personal. It depends on what an individual values, fears, and believes about the change. Your role as a leader is to understand those individual motivations and address them directly, not to assume that a compelling business case automatically translates into personal buy-in.
Knowledge, Ability, and Reinforcement: the execution layer
Knowledge covers what an individual needs to know to change: the new skills, processes, systems, or behaviors required. This is where training and education belong in the model. The critical insight is that Knowledge only produces results when Awareness and Desire are already in place. Investing heavily in training before you have addressed motivation is one of the most common and costly mistakes organizations make during a change rollout.
Ability is the practical outcome that follows Knowledge, and it represents whether a person can actually perform the new behavior in real working conditions. Practice, coaching, and structured feedback build Ability over time. Reinforcement, the fifth element, ensures the change sticks by creating accountability structures and recognition systems that make reverting to old behavior less likely. Without reinforcement, even well-executed changes tend to fade.
PCT model explained: how to assess change health
The Project Change Triangle (PCT) Model is the diagnostic tool within the prosci change management model that operates at the initiative level rather than the individual level. Where ADKAR tells you whether a specific person is moving through change effectively, the PCT Model tells you whether your entire change initiative has the structural conditions it needs to succeed. Think of it as a health check you run on the project itself, not on the people involved.
The three dimensions of the PCT Model
The PCT Model identifies three interdependent dimensions that every change initiative must manage simultaneously. A weakness in any single dimension creates risk across the others, which is why the model presents them as a triangle rather than a linear checklist.
| Dimension | What it covers | Why it matters |
|---|---|---|
| Leadership/Sponsorship | Active, visible support from senior leaders who own the change | Without committed sponsors, resistance goes unaddressed and resources get pulled |
| Project Management | The technical and logistical side: scope, budget, timeline, deliverables | A poorly managed project undermines even the best people-side work |
| Change Management | The people side: communication, coaching, training, resistance management | Without this, adoption stalls regardless of how well the project delivers |
Each dimension must be healthy and aligned with the other two. Strong project management combined with weak sponsorship produces a technically delivered change that nobody adopts. Strong sponsorship with weak change management produces well-intentioned leadership that never translates into behavioral shift at the front line.
How to use the PCT Model as a diagnostic tool
You use the PCT Model by rating each dimension at regular intervals throughout your initiative and identifying which dimension is creating the most drag on overall change success. Prosci provides a structured assessment tool for this, but even an informal review of the three areas reveals patterns quickly.
When sponsorship is your weakest dimension, your first priority is not to build more training; it is to strengthen the visible commitment of the leaders who own the change.
Pay particular attention to leadership/sponsorship as the highest-leverage dimension. Research from Prosci’s benchmarking studies consistently identifies active and visible executive sponsorship as the single most important factor in change success. If your sponsor is delegating change management entirely to a project team without staying personally engaged, the PCT assessment will surface that gap before it becomes a project failure.
The Prosci 3-Phase Process explained
The Prosci 3-Phase Process is the operational backbone of the prosci change management model. It takes the individual-level insights from ADKAR and the initiative-level diagnostics from the PCT Model and organizes them into a sequenced set of activities you can run on a real project. The three phases are Prepare Approach, Manage Change, and Sustain Outcomes. Each phase produces specific outputs that feed directly into the next, so skipping or shortcutting any phase creates predictable gaps that surface later in the rollout.
Phase 1: Prepare Approach
Phase 1 is where you define the scale and complexity of the change before committing significant resources or executing any activities. You assess which groups of people are impacted, how much change each group faces, and what risks and resistance points you’re most likely to encounter. The output is a tailored change management strategy that reflects the actual nature of your initiative rather than a recycled plan from a previous project.
- Clarify scope, timeline, and expected individual impact
- Identify impacted groups and the degree of change each group faces
- Assess organizational capacity for change and relevant change history
- Develop your sponsorship model and overall change management strategy
Phase 2: Manage Change
Phase 2 is where most of the visible change management work happens. You develop and execute the specific plans that move people through the ADKAR outcomes: communication plans, sponsor roadmaps, coaching guides, training plans, and resistance management plans. Each plan targets a specific barrier to individual adoption and is delivered through the management chain rather than around it.
The manager channel is your highest-value communication asset in Phase 2 because employees consistently rank their direct manager as their most trusted source of information during a change.
Running these plans well requires active coordination between your change practitioner, the project team, and the sponsor. Treat each plan as a living document that you update regularly based on adoption feedback and behavioral data collected throughout the phase, not as a static deliverable produced at the start.
Phase 3: Sustain Outcomes
Phase 3 is the most frequently skipped and the most consequential step in the entire process. Your job here is to measure actual adoption, identify gaps between intended and real behavior change, and activate corrective actions before momentum fades. You also formally transfer ownership of the change to the business unit responsible for sustaining it.
Sustaining outcomes requires structured accountability mechanisms embedded in normal business operations rather than maintained by a temporary project team. Without those mechanisms, changes that appeared successful at launch quietly erode as old habits return and no one is formally responsible for catching the regression.
How to apply Prosci on a real change initiative
Knowing the components of the prosci change management model is different from knowing how to use it when you have an actual initiative in front of you. The steps below translate the framework into a practical sequence you can follow from the moment a change is scoped through the point where new behaviors are embedded in daily operations.
Start with a clear definition of success at the individual level
Before you build any plans, define what successful change looks like for the specific people this initiative touches. Identify the groups most affected by the change and describe, in concrete behavioral terms, what each group needs to do differently when the rollout is complete. That definition becomes your reference point for every communication, coaching, and training activity you design.
Once you have that definition, run a quick ADKAR assessment with a representative sample of the impacted population. Ask targeted questions about each element to find out where each group currently sits. If most people lack Awareness, your first action is communication, not training. The assessment prevents you from investing resources in the wrong activity at the wrong moment.
Your change management effort should be sized to match the scale of behavioral change required, not the scale of the technical project.
Build your sponsor model before you build your plans
Most practitioners jump straight to communication and training plans. The more high-leverage move is to secure and structure your sponsorship first. Identify your primary sponsor, clarify their specific role, and build a roadmap of the actions they need to take at each phase of the initiative. An engaged sponsor who actively communicates, removes barriers, and addresses resistance publicly multiplies the effectiveness of everything else you run.
A practical sponsor roadmap identifies the specific audiences the sponsor needs to reach, the messages they need to deliver, and the decision points where their visible involvement matters most. Share it with them directly and treat it as a working agreement, not a formality you file and forget.
Treat adoption data as a project metric
Track actual behavioral adoption throughout Phase 2 using structured feedback loops: pulse surveys, manager check-ins, and usage data from any new systems or processes involved. Report adoption metrics alongside traditional project metrics in your regular status updates so that resistance and knowledge gaps receive the same operational attention as budget and timeline variances. When you treat adoption as a measurable output, course-correcting becomes standard project management rather than a late-stage crisis response.
Common mistakes and how to fix them
Even practitioners who understand the prosci change management model well often fall into predictable patterns that limit their results. The good news is that these mistakes are recognizable early if you know what to look for, and each one has a clear correction that doesn’t require restarting your initiative from scratch.
Treating ADKAR as a checklist instead of a diagnostic
The most common misuse of ADKAR is treating each element as a box to check rather than an outcome to verify. You send one announcement email and mark Awareness as complete. You run a two-hour training session and declare Knowledge achieved. But ADKAR elements are not activities; they are states that individuals either have or don’t have at any given point in the process.
ADKAR only tells you where individuals are stuck if you actually measure it; assuming adoption without evidence is the most expensive mistake in any change rollout.
The fix is to collect structured feedback from impacted employees at each stage rather than assuming that delivering an activity automatically produces the intended outcome. Brief pulse surveys or direct manager conversations give you the adoption signal you need to course-correct before gaps compound.
Skipping Phase 1 to save time
Organizations under pressure frequently skip Phase 1 (Prepare Approach) and jump straight into building communication and training plans. This feels productive in the short term, but it produces plans that are disconnected from the actual scale of the change. Without a proper impact assessment and risk analysis, your plans address the change you assumed you had rather than the one your employees are actually experiencing. Spend the time upfront to define the scope of behavioral change each impacted group faces. That investment returns as fewer expensive course corrections during execution.
Underestimating the sponsorship requirement
Many leaders believe their role in a change initiative is to approve it and then delegate execution. That model breaks down because employees watch senior leaders closely for signals about whether a change is real, lasting, and worth committing to. When your sponsor disappears after the launch announcement, people read that absence as a lack of conviction and adjust their own commitment accordingly.
The fix is to build a concrete sponsor roadmap that specifies exactly what your sponsor needs to do, who they need to communicate with, and when their visible involvement matters most throughout the rollout. Active sponsorship is your single highest-leverage factor in driving real adoption.
Next steps you can take now
The prosci change management model gives you a structured, research-backed way to close the gap between launching a change and actually embedding it. Start by picking your next initiative and running a quick ADKAR assessment with a representative sample of the people it affects. That single step will tell you where to focus your energy first, whether that’s building awareness, securing stronger sponsorship, or closing knowledge gaps before you invest in training. From there, build your sponsor roadmap, develop your three-phase plan, and measure behavioral adoption as a real project metric throughout the rollout.
