ADKAR Model

A goal-oriented change management framework developed by Prosci that breaks individual change into five sequential stages: Awareness, Desire, Knowledge, Ability, and Reinforcement, giving organizations a structured way to drive adoption one person at a time.

What Is the ADKAR Model?

Key Takeaways

  • ADKAR is a change management model created by Jeff Hiatt, founder of Prosci, that focuses on individual transitions rather than organizational-level planning.
  • The five elements (Awareness, Desire, Knowledge, Ability, Reinforcement) must happen in sequence. Skipping stages is the primary reason change efforts stall.
  • Projects with excellent change management are 6 times more likely to meet their objectives than those with poor change management (Prosci, 2023).
  • Unlike Kotter's model (which focuses on organizational steps), ADKAR zooms in on what each person needs to successfully adopt a change.
  • HR teams use ADKAR to diagnose exactly where resistance is coming from and apply targeted interventions instead of blanket communication campaigns.

The ADKAR Model is a change management framework that treats organizational change as something that happens one person at a time. Developed by Jeff Hiatt at Prosci in the late 1990s, it breaks individual change into five sequential building blocks: Awareness of why the change is needed, Desire to participate and support it, Knowledge of how to change, Ability to implement the change day to day, and Reinforcement to sustain it over time. Here's why this matters for HR: most change programs focus on the organizational side. They create project plans, communication strategies, and training schedules. But they forget that organizations don't change. People do. If even one of those five building blocks is missing for an individual employee, they won't make the transition. ADKAR gives you a diagnostic tool to figure out exactly where each person (or group) is stuck. Is the sales team aware of the new CRM but doesn't want to use it? That's a Desire problem, not a Knowledge problem. Sending more training won't fix it. Prosci's 2023 benchmarking study found that 84% of organizations using structured change management met or exceeded their project objectives. That's not accidental. Structured models like ADKAR prevent teams from solving the wrong problem.

What Are the Five Elements of ADKAR?

Each element represents a milestone that an individual must reach before moving to the next. Think of them as gates: you can't skip ahead.

Awareness: Why is this change happening?

Awareness isn't just knowing that a change is coming. It's understanding the business reasons behind it, the risks of not changing, and how it connects to the organization's direction. Most companies rush past this stage. They announce the change in an email, check the "communication" box, and move on. But awareness requires repetition across multiple channels: town halls, manager conversations, written FAQs, and direct answers to "what does this mean for me?" Research from Prosci shows that the primary sender of awareness messages should be the employee's direct supervisor for personal impact and senior leadership for business reasons. One email from the CEO doesn't create awareness. It creates noise.

Desire: Do I want to participate?

This is where most change efforts hit their first wall. An employee can fully understand why a change is happening and still not want to do it. Desire is personal. It's driven by factors like "what's in it for me," fear of what they'll lose, trust in leadership, and peer influence. You can't mandate desire. Telling people they must adopt a new process creates compliance at best and sabotage at worst. Building desire requires showing personal benefits, addressing fears directly, involving people in shaping the implementation, and ensuring managers visibly support the change. Prosci's data shows that direct managers have the greatest influence on employee desire, which is why manager coaching is critical in any ADKAR implementation.

Knowledge: Do I know how to change?

Knowledge covers the information, training, and education needed to change. This includes understanding new processes, learning new tools, knowing new behaviors expected, and understanding new roles or reporting structures. Knowledge comes through formal training, job aids, coaching, and practice environments. A common mistake is delivering training too early (before awareness and desire are established) or too late (after go-live, when people are already frustrated). The timing of knowledge transfer matters as much as the quality.

Ability: Can I actually do it?

Knowledge and ability aren't the same thing. You can know how to use a new software platform and still struggle with it daily. Ability is the demonstrated capability to perform the change in the real work environment. It develops through practice, coaching, hands-on experience, and time. The gap between knowledge and ability is often underestimated. Training someone on a new system in a classroom setting doesn't mean they can use it effectively under time pressure with real data. Ability building requires ongoing support, accessible help resources, patience from managers, and a safe environment to make mistakes during the learning curve.

Reinforcement: Will this change stick?

Without reinforcement, people revert to old habits. Reinforcement includes celebrations of success, recognition of adoption, accountability mechanisms, feedback loops, and corrective action when people slip back. Prosci's research shows that 70% of organizations that neglect reinforcement experience significant regression within 6 months of go-live. Effective reinforcement is both positive (rewards and recognition for new behaviors) and structural (removing the option to use old systems, updating KPIs to reflect new processes). It's not a one-time event. It's an ongoing effort that typically takes 3 to 6 months after the change goes live.

How Do You Run an ADKAR Assessment?

The ADKAR assessment is a diagnostic tool that scores each employee (or group) on each of the five elements, revealing exactly where resistance or gaps exist.

Scoring methodology

Rate each element on a 1-to-5 scale through surveys, manager observations, or one-on-one conversations. A score of 3 or below on any element is a "barrier point," the stage where that person is stuck. The first barrier point is the one to address. There's no benefit in building knowledge for someone who doesn't have desire yet. Focus interventions on the lowest-scoring element that comes first in the sequence.

Group-level patterns

When you aggregate ADKAR scores across a team or department, patterns emerge. If 80% of the engineering team scores low on Awareness, your communication hasn't reached them. If the sales team scores high on Awareness and Knowledge but low on Desire, they understand the change but don't want it. Each pattern requires a different intervention. This diagnostic precision is what makes ADKAR more actionable than generic resistance management.

ADKAR ElementCommon Barrier Point SymptomsRecommended Interventions
Awareness"I didn't know this was happening" or "Why are we doing this?"Executive communication, business case sharing, manager talking points, town halls
Desire"I don't want to change" or "What's in it for me?"Manager coaching, personal impact discussions, involving employees in design, addressing fears
Knowledge"I don't know how to do this" or "The training was unclear"Role-specific training, job aids, demos, peer learning sessions, FAQ documents
Ability"I know how but I keep making mistakes" or "It's too hard in practice"Hands-on coaching, practice time, help desk support, buddy systems, reduced workload during transition
Reinforcement"We used to do it better" or reverting to old processesRecognition programs, performance metrics tied to new behaviors, removing old systems, celebrating milestones

ADKAR vs Kotter's 8-Step Model vs Lewin's Change Model

Each model addresses change from a different angle. They're not competing frameworks. Many organizations use them together.

How Do You Apply ADKAR in Practice?

Theory without application is useless. Here's how HR teams actually use ADKAR in real change scenarios.

HRIS implementation example

A mid-size company rolling out Workday to replace spreadsheets and legacy systems. Awareness phase: the CHRO presents the business case (manual processes causing payroll errors costing $200K/year). Desire phase: managers hold one-on-ones explaining how the new system saves each employee 3 hours per week on self-service tasks. Knowledge phase: role-specific training for HR admins, managers, and employees (not one generic session for everyone). Ability phase: a 4-week parallel-run period where both old and new systems operate. Reinforcement phase: the old system is decommissioned after 90 days, and adoption dashboards are shared weekly.

Return-to-office mandate example

Awareness: leadership explains the data behind the decision (collaboration metrics, mentorship gaps, client feedback). Desire: rather than mandating five days, the company offers three in-office days with flexibility on which three. They address fears about commute costs with a transit subsidy. Knowledge: clear guidelines on booking desks, meeting room protocols, and hybrid meeting etiquette. Ability: managers receive coaching on leading hybrid teams. IT sets up seamless video conferencing in every room. Reinforcement: monthly pulse surveys track satisfaction, and leadership publicly adjusts the policy based on feedback after 90 days.

Merger integration example

During a merger, ADKAR helps HR address the fact that employees from both companies are going through change, but their barrier points differ. The acquiring company's employees might score high on Awareness but low on Desire (they didn't ask for this). The acquired company's employees might score low on everything because they feel powerless. ADKAR assessments run separately for each population, and tailored interventions address each group's specific gaps. This precision is why ADKAR is popular in M&A playbooks.

Common Mistakes When Using the ADKAR Model

ADKAR is simple to understand but easy to misapply. These mistakes undermine even well-resourced change programs.

  • Treating ADKAR as a communication plan. Awareness is only one of five elements. Teams that create beautiful slide decks but don't address Desire, Knowledge, Ability, or Reinforcement are doing 20% of the work.
  • Skipping Desire and jumping to training. You'll see this constantly: a company announces a change, immediately schedules training, and then wonders why attendance is low and adoption is poor. People who don't want to change won't learn how to change.
  • Running a single ADKAR assessment and never revisiting. People's barrier points shift as the change progresses. Someone stuck on Desire in month one might move to a Knowledge gap by month three. Reassess quarterly at minimum.
  • Applying ADKAR only to the "end users" of a change. Managers, executives, and HR team members go through ADKAR too. A manager who hasn't reached Desire will never coach their team through the same stage.
  • Confusing Knowledge with Ability. Sitting through a training session creates Knowledge. Being able to perform the new process under real conditions, with real time pressure, creates Ability. They require different interventions.
  • Stopping at go-live and neglecting Reinforcement. This is the most commonly skipped element. Without it, adoption rates typically drop 30 to 50% within 6 months (Prosci).

Frequently Asked Questions

Who created the ADKAR Model?

Jeff Hiatt, the founder of Prosci, created ADKAR in the late 1990s after studying over 700 organizations going through change. He published the framework formally in his 2006 book "ADKAR: A Model for Change in Business, Government, and Our Community." Prosci continues to develop and validate the model through their ongoing benchmarking studies, which now include data from over 6,000 change practitioners worldwide.

Is ADKAR only for large organizations?

No. ADKAR works at any scale because it focuses on individuals, not organizational size. A 50-person startup implementing a new project management tool benefits from ADKAR the same way a 50,000-person enterprise does during an ERP migration. The complexity of the change matters more than the headcount. Smaller organizations often find ADKAR easier to apply because they can have direct conversations with every affected person.

Can you use ADKAR alongside Kotter's model?

Yes, and many organizations do. Kotter's 8-Step Model addresses the organizational side of change (building coalitions, creating vision, generating wins). ADKAR addresses the individual side (what each person needs to adopt the change). They complement each other. Use Kotter's steps to plan and sequence the organizational effort. Use ADKAR to diagnose and support individual adoption. Prosci's own methodology maps ADKAR elements to organizational activities in this way.

How long does it take to move someone through all five ADKAR elements?

It depends entirely on the change's complexity and the individual's starting point. A simple process change might take 2 to 4 weeks per person. A major technology overhaul or cultural shift can take 6 to 12 months. The Desire stage typically takes the longest because it involves personal motivation, which can't be rushed. Prosci's data shows that the average enterprise change initiative takes 18 to 24 months from awareness through sustained reinforcement.

What's the biggest weakness of the ADKAR Model?

ADKAR's individual focus is both its strength and its limitation. It doesn't directly address organizational politics, power dynamics, resource allocation, or structural barriers to change. If a VP is actively sabotaging a change initiative, no amount of individual ADKAR coaching will fix the problem. You need organizational-level interventions (coalition building, executive alignment) that models like Kotter's handle better. That's why experienced change practitioners use multiple models together.

Is ADKAR certification worth it for HR professionals?

If you're regularly involved in change initiatives, yes. Prosci's Change Management Practitioner certification (which teaches ADKAR as the core framework) is one of the most recognized credentials in the field. It runs about $4,500 for the three-day program. The certification gives you a common language with other practitioners, access to Prosci's benchmarking data, and practical tools you can apply immediately. For HR business partners and OD professionals, it's one of the highest-ROI certifications available.
