Most change initiatives inside organizations don’t fail because the strategy was wrong. They fail because people weren’t ready. The ADKAR model Prosci developed addresses exactly this gap, it shifts the focus from project plans and timelines to the individual human beings who actually have to do things differently. That distinction matters more than most leaders realize.
At Robyn Benincasa’s core, our work centers on helping teams perform under pressure, adapt to shifting conditions, and commit to outcomes bigger than any one person. Whether it’s navigating a merger, breaking down silos, or rallying a sales force around a new direction, the human side of change is where results are won or lost. The ADKAR framework gives leaders a structured way to think about that human side, and it pairs well with the teamwork-driven approach we bring to organizations every day.
This article breaks down all five building blocks of the ADKAR model, Awareness, Desire, Knowledge, Ability, and Reinforcement, and shows you how to put each one to work. You’ll walk away with a clear understanding of the framework and practical ways to apply it inside your own team or organization.
What the Prosci ADKAR model is
The ADKAR model is a goal-oriented change management framework built around five outcomes that every individual must reach for a change to stick. The acronym stands for Awareness, Desire, Knowledge, Ability, and Reinforcement. Unlike frameworks that focus on process steps or project timelines, ADKAR zeroes in on the person going through the change. Each letter represents a specific building block, and a person has to clear each one before the next becomes useful.
ADKAR works because it treats change as something that happens to a person, not to a project plan.
Where ADKAR came from
Prosci, the research and training organization behind the framework, developed ADKAR based on studies conducted with more than 700 organizations in the late 1990s. Founder Jeff Hiatt studied why some changes landed and others collapsed, and the pattern he found was consistent: success or failure almost always traced back to individual adoption. Hiatt published the model formally in 2006 in his book ADKAR: A Model for Change in Business, Government and our Community.
The adkar model prosci created didn’t come from theory alone. It came from watching real organizations attempt real change and tracking what the people inside those organizations actually needed to move forward. That grounding in observed behavior is a big reason the framework has held up for nearly three decades and remains one of the most widely used change management tools in the world today.
The goal behind the framework
The framework exists to give leaders and managers a precise diagnostic tool, not just another communication checklist. When a change initiative stalls, ADKAR helps you pinpoint exactly where the breakdown happened. If someone has Awareness but no Desire, they understand the change but don’t want it. If someone has Knowledge but no Ability, they know what to do but can’t execute it yet. Each gap has a different cause and a different fix.
This precision matters because most change efforts treat resistance as a single, uniform problem. They respond with more announcements, more training, or more pressure, without diagnosing what’s actually missing for the individuals involved. ADKAR forces you to slow down and ask a more useful question: where specifically is this person stuck? When you can answer that, you can target your support instead of spreading it thin. That shift from broadcasting change to supporting individuals through it is what separates organizations that complete transformations from the ones that keep restarting them.
How ADKAR fits into change management
Change management covers a wide range of practices, from stakeholder communication to project governance, but most frameworks operate at the organizational level. They focus on timelines, workstreams, and deliverables. ADKAR operates at a different level entirely. It focuses on the individual inside the organization, which is where change either takes hold or quietly dies.
ADKAR within the broader Prosci methodology
The adkar model Prosci built sits at the center of a larger methodology that also includes the PCT Model (People, Process, and Context) and a structured three-phase change process. You can use ADKAR as a standalone diagnostic tool, but inside Prosci’s full system, it serves as the measure of whether your change management efforts are working at the individual level. Think of the broader methodology as the map and ADKAR as the instrument that tells you whether each person is actually moving across the terrain.
ADKAR tells you not just that a change is stuck, but exactly where and with whom it’s stuck.
The difference between organizational and individual change
Most organizations track project milestones: system launch dates, policy rollout deadlines, training completion rates. Those metrics tell you what happened at the organizational level. They don’t tell you whether the people who showed up to training actually left with the confidence and capability to change their behavior. That gap between organizational progress and individual adoption is where most change efforts fall apart.
ADKAR bridges that gap by giving you a common language to assess readiness at the person level. When your HR team, frontline managers, and senior leaders all use the same five building blocks to evaluate where people are in the change journey, you stop having vague conversations about "resistance" and start having specific conversations about what support each person actually needs. That specificity accelerates adoption across the entire organization.
The five ADKAR building blocks explained
The adkar model Prosci built treats each of the five building blocks as a required checkpoint, not an optional step. A person who skips one doesn’t simply fall behind; they hit a wall that stops all further progress. Each building block stacks directly on the one before it, which means the sequence matters as much as the content itself. Understanding what each block actually means helps you deploy the right support at the right time.
| Building Block | What it means |
|---|---|
| Awareness | Understanding why the change is happening |
| Desire | Choosing to support and participate in the change |
| Knowledge | Knowing how to change |
| Ability | Being able to implement the change consistently |
| Reinforcement | Sustaining the change over time |
Awareness, Desire, and Knowledge
These first three blocks form the motivational and cognitive foundation of change. Awareness answers the question of why: why is this change necessary, and what does the organization risk by not making it? Desire goes a step further, because understanding the reason isn’t the same as wanting to act on it. A person can fully grasp the rationale and still choose not to engage. Knowledge then shifts the focus to how: what specific behaviors, skills, and processes does this person need to learn? This is where many leaders make their first mistake by delivering heavy training programs before people have moved through Awareness and Desire, leaving employees with knowledge they have no motivation to use.
You can inform people all day, but until they want the change and know how to execute it, nothing moves.
Ability and Reinforcement
Ability is where many change initiatives quietly break down. A person can attend every training session and still struggle to perform the new behavior under real working conditions. Ability requires practice, coaching, and enough time to convert knowledge into consistent execution. Reinforcement closes the loop by making the new behavior the default. It is often treated as a nice-to-have, but without recognition, accountability structures, and visible consequences, people drift back to familiar habits and the change investment evaporates within weeks of the initial rollout.
How to apply ADKAR step by step at work
Applying the adkar model Prosci developed isn’t complicated, but it does require discipline. The most common failure mode is treating it as a one-time checklist instead of an ongoing diagnostic that you return to throughout the entire change process. The five building blocks only work when you use them as a living tool, not a form you fill out on launch day and file away.
Start with a change readiness assessment
Before you roll out any change, assess where each person currently sits across all five building blocks. You don’t need a lengthy survey. A simple one-on-one conversation with each direct report, guided by the five ADKAR elements, gives you enough information to identify gaps before they become blockers. Ask whether people understand the reason behind the change, whether they believe in it, and whether they feel equipped to act on it. Map the results so you can see exactly which building blocks are missing across your team and where to focus your energy first.
Spend more time diagnosing before the change launches than you think you need to, because gaps found early cost far less to close than gaps found after rollout.
Use managers as the primary change channel
Managers are the single most powerful lever you have when applying ADKAR inside a real organization. Research from Prosci consistently shows that employees prefer to hear about changes that affect their work directly from their immediate supervisor, not from company-wide emails or town halls. Train your managers to recognize each ADKAR building block in conversations with their teams and to respond with targeted support rather than generic reassurance.
Reinforcement, the final block, is where manager accountability becomes non-negotiable. Schedule structured check-ins after a change goes live to confirm that new behaviors are sticking, recognize the people who have made the shift, and address backsliding quickly before it spreads across the team.
Common ADKAR mistakes and how to avoid them
Even well-intentioned leaders make predictable errors when applying the adkar model Prosci developed. Most of these mistakes share a common thread: they prioritize organizational convenience over individual readiness, which is the exact opposite of what the framework is designed to do. Recognizing these patterns before they take root saves you time, budget, and the goodwill of the people you need to bring along.
Jumping straight to training
The most widespread mistake is launching knowledge-building activities before people have moved through Awareness and Desire. Sending your team to a two-day training session while they still question why the change is happening guarantees low retention and high resentment. Knowledge only sticks when people already understand the reason behind the change and have chosen to engage with it.
If your training rooms are full but your adoption numbers are empty, check whether Awareness and Desire were ever truly established.
Fixing this mistake is straightforward. Before you schedule any training, confirm that every person affected can articulate why the change is necessary and what it means for their specific role. If they can’t, you have more foundational work to do first.
Ignoring reinforcement after launch
Many organizations declare victory at go-live, which is precisely when the real work begins. Without structured reinforcement, the new behaviors compete against years of ingrained habits and almost always lose within the first few weeks. The absence of recognition, follow-up conversations, and visible accountability signals to people that the change wasn’t actually serious.
Build reinforcement into your plan before you launch, not after you notice people slipping back. Assign your managers specific check-in milestones, recognize early adopters publicly, and address backsliding with direct coaching rather than blanket reminders. Reinforcement is not a bonus step; it is the building block that locks in everything the previous four steps built.
What to do next
The adkar model Prosci developed gives you a framework that cuts through the noise of organizational change and focuses on what actually determines success: whether each individual in your organization moves through all five building blocks completely. You now have a clear picture of what each block means, how they connect, and where most change efforts go wrong. The next step is to take that knowledge into a real conversation with your team, run a simple readiness assessment before your next initiative, and commit to reinforcing new behaviors well past the launch date.
Change at scale starts with one person at a time, and the leaders who understand that consistently outperform the ones who rely on announcements and slide decks.
