ADKAR Model: What It Is and How It Works

The ADKAR (Awareness, Desire, Knowledge, Ability, Reinforcement) model is a structured, individual-focused change management framework created by Prosci that guides people through five sequential stages. Organizational change only succeeds when each person affected makes a successful transition, so the model diagnoses and resolves barriers at the personal level before change can take hold across a team or an entire company.

What is the ADKAR model and where does it come from?

The ADKAR model is an outcome-oriented change management framework developed by Prosci, a research-based change management organization. The model is built on the premise that organizational change is the sum of individual changes. If any single stage is incomplete for a given person, the overall change initiative hits a barrier point at that individual.

The five building blocks of the Prosci ADKAR model are:

Why use the ADKAR change model over other frameworks?

The ADKAR model of change management stands out because it pinpoints exactly where a change is breaking down for a specific individual, rather than treating the organization as a uniform block. Most change initiatives stall not because the strategy is wrong, but because individual people are stuck at one of the five stages.

Key advantages include:

• Targeted diagnosis: A manager can identify whether an employee lacks awareness, desire, or ability, then apply the right intervention rather than a generic one.
• Reduced resistance: By addressing the root cause of each person's resistance to organizational change, the model prevents blockages from spreading across teams.
• Better return on investment: Changes that reach the Reinforcement stage are more likely to be sustained, improving the long-term return on technology and process investments.
• Scalable from individual to organization: Once each person moves through all five stages, individual progress aggregates into measurable organizational change.

"Every technological change must be accompanied, often step by step. Teams sometimes told me, a year and a half later: I finally understand why you changed that six months ago."

Mathieu Blin, DSI, Motul, on the Lemon Learning podcast

When should you apply the ADKAR methodology?

The ADKAR change management model is most valuable when a change requires people to actually work differently, not just when a process is updated on paper. It is the primary tool for the project manager, business leader, and change agent responsible for guiding teams through transitions.

Common use cases include:

• Rolling out new enterprise software, SaaS platforms, or digital tools
• Restructuring teams or reporting lines
• Introducing new compliance or regulatory requirements
• Scaling a new process across multiple departments

The model also helps identify where a live initiative is already struggling. If employees have been trained but are not changing their behavior, the barrier is likely at the Ability or Reinforcement stage rather than the Knowledge stage. This distinction prevents teams from repeating training that will not resolve the actual problem. For a broader view of how this fits into a structured program, see the guide to a successful change management process.

How do you apply the ADKAR model step by step?

Applying the ADKAR model means moving each individual through all five stages in sequence. Skipping a stage creates a gap that will surface later as resistance, low adoption, or regression to old behaviors.

Awareness and Desire: building the will to change

Start by communicating the business reason for the change clearly and honestly. Employees who understand why a change is happening are far more likely to develop the desire to support it. For individuals who remain reluctant, the direct manager must address personal motivations and concerns one to one. Addressing resistance to change at this early stage is far less costly than attempting to correct it after rollout.

Knowledge and Ability: building the skill to change

Once employees want to change, they need to know how. Structured training, coaching sessions, and job aids deliver the Knowledge component. The Ability stage then requires practice - employees need real opportunities to apply new skills in context, on the actual tools or processes involved. The gap between knowing and doing is often wider than anticipated, and patience at this stage pays off in sustained adoption.

Reinforcement: making the change last

Reinforcement is the most frequently neglected stage of the ADKAR change model. Recognizing progress, conducting follow-up audits, and correcting drift back to old habits are all essential to locking in the change. Lemon Learning's change management solution supports this stage by delivering in-application guidance that reinforces new workflows at the moment of use, reducing the need for repeated retraining and sustaining long-term employee development.

The ADKAR model for change management provides a clear, actionable structure for any change initiative. By identifying and resolving the specific stage where each individual is stuck, change leaders can move from initiative launch to sustained adoption with far greater consistency and confidence.
