ADKAR Model: A Guide to Delivering Lasting Organisational Change

The ADKAR model sits at the heart of effective change management because it recognises a simple truth: organisations only change when their people change. It gives leaders a clear structure for understanding how individuals move through change and highlights that people are central to every transformation. Strategies shift, technologies develop and teams adjust their ways of working – but long-term success depends on how well people connect with the organisation’s purpose and how smoothly the change is delivered.

The five ADKAR outcomes – Awareness, Desire, Knowledge, Ability and Reinforcement – help leaders see where people are in their own change journey and what support they need to move forward. By focusing on these outcomes, leaders can give targeted communication, training and coaching that reflects real readiness. Whether the change is cultural, technical or structural, ADKAR provides a consistent, practical framework that helps drive adoption, reduce resistance and build lasting change.

This article explains how the model works, why it adds value and how to use it to support successful transformation.

The ADKAR Model was created by Jeff Hiatt, the founder of Prosci, after studying how people responded to change in more than 700 organisations. His research showed a common problem: organisations were investing heavily in new systems, processes and projects, but many initiatives still failed. People were left unclear about expectations, received mixed messages and often did not get the support they needed.

ADKAR was developed to close this gap by breaking the human experience of change into five clear, measurable outcomes. Prosci later expanded the model into a full methodology that connects project delivery, leadership behaviour and employee adoption. Today it is used across digital programmes, culture shifts, mergers, operating model changes and compliance work, and it often sits alongside agile and programme management approaches.

The core purpose of ADKAR has stayed the same: to make people’s adoption of change something leaders can understand, influence and measure.

ADKAR describes the stages individuals move through during any change:

Leaders value ADKAR because it uses a shared, simple language and focuses on outcomes rather than ticking off tasks. It keeps attention on people, helping leaders understand how their actions influence the pace and consistency of adoption.

Leaders often sense when a change is slowing down but may not know why. ADKAR helps identify the missing outcome. Low awareness creates confusion; weak desire leads to quiet resistance; gaps in knowledge or ability show up as mistakes or delays; poor reinforcement allows old habits to return.

Using the ADKAR model improves decision-making by revealing trends across teams and helping leaders act quickly. It also gives HR, project teams and sponsors a common language for discussing progress.

ADKAR only works when it reflects real experience. If it becomes a box-ticking exercise, it loses its human focus and reduces trust. While ADKAR is sequential, real change does not move in a straight line. Awareness may need refreshing, especially during long programmes or when new people join. In agile environments, ADKAR blends well with sprint planning, release cycles and continuous reinforcement.

Each stage builds on the previous one. When applied consistently, ADKAR helps leaders anticipate challenges and build momentum.

39% of employees said that a lack of awareness around the reason for change makes them the most resistant to change. Awareness is about clarity: people need to know why the organisation is changing, what problem is being solved and what happens if nothing changes. Without this, they fill the gaps with their own assumptions.

Common barriers include limited transparency, inconsistent messages and anxiety fuelled by rumours.

Leaders build awareness by:

Desire is the turning point in any change. It reflects a personal decision to support what’s coming. People consider how the change affects their workload, their role, their confidence and their trust in leaders. Desire grows when employees feel engaged, listened to and involved.

Common barriers include past failures, high workload and uncertainty.

Leaders build desire by:

Knowledge gives people the information, skills and context they need to work in new ways. Training alone is not enough – they need clarity about expectations and time to digest what is changing.

The word ‘impact’ often has a negative connotation, but the change can impact people positively. Through good communication and giving people the tools to understand and recognise why it is happening, leaders take people with them on the change journey rather than dragging them along.

Common barriers include poorly training design, too much information at once and unclear processes.

Leaders build knowledge by:

Ability grows through practice. Even well-trained teams need time, support and the right tools. 83% of change-fatigued employees feel their employer doesn’t offer tools to support their adaption to workplace changes. People need safe spaces to try new behaviours and receive feedback.

Common barriers include outdated systems, unclear workflows, limited coaching or competing priorities.

Leaders accelerate ability by:

Reinforcement locks in new habits to ensure the change sticks. Without it, people naturally return to old routines. Reinforcement includes recognition, accountability, measurement and ongoing support.

Common barriers include old habits resurfacing, lack of accountability, or unclear ownership of the new process.

Leaders reinforce change by:

Our experience supporting a clinical-trial documentation programme illustrates this progression in action. By taking the complex global audience through each ADKAR stage systematically, the programme achieved a visible shift in mindset, built stronger capability and established sustained compliant working practices. The outcomes were both measurable and enduring, including a documented 30% increase in knowledge levels. You can read the full case study here to explore the impact.

ADKAR execution becomes more effective when backed by supportive organisational infrastructure. Crucially, this infrastructure only functions properly when leaders are unified on direction and timing; without cohesive sponsorship, even the strongest ADKAR plan will struggle to get off the ground.

Useful supporting structures include:

This infrastructure helps leaders turn ADKAR theory into everyday practice.

For example, we supported a global infrastructure business that wanted employees to treat data and information as critical assets alongside their physical infrastructure. By helping them establish strong supporting structures – governance, aligned messaging, capability tracking, engaging events and a connected community of information risk owners and champions – the ADKAR stages became far easier to achieve. This infrastructure amplified awareness, fostered desire, developed capability and reinforced new behaviours, creating a confident network that managed information with improved consistency and accountability.

Seeing how ADKAR sits alongside other models helps leaders pick the right tool for different situations.

When ADKAR Works Best

The model performs particularly well in operational changes, technology deployments, compliance-driven changes and settings where required behaviours are well-defined. For highly uncertain innovation work where outcomes are still taking shape, ADKAR often works effectively alongside other approaches as a supporting element.

Organisations select ADKAR because it’s straightforward, scalable and action-oriented. Key benefits include:

ADKAR establishes a shared vocabulary for change, cutting through confusion and aligning expectations across the organisation.

For example, a pharmaceutical organisation redefining its Design function used an ADKAR-led survey to benchmark perceptions and tailor its value proposition. This evidence-based approach strengthened awareness, generated desire for a fresh narrative and underpinned a wider shift positioning Design as an embedded partner – demonstrating how ADKAR facilitates precise, people-focused change.

Even with a solid framework, organisations can hit predictable problems during implementation. Leaders need to watch out for:

Leaders can sidestep these problems by:

Change only succeeds when the people experiencing it succeed. The ADKAR Model gives leaders a practical mechanism to understand, support and accelerate that journey. It breaks transformation down into a series of definite outcomes: awareness, desire, knowledge, ability and reinforcement.

Used as both a planning tool and a measurement instrument, ADKAR brings clarity and rigour to change work. It improves communication, develops capability and establishes the right conditions for sustainable adoption. Senior leaders who embed ADKAR into their transformation approach see quicker alignment, cleaner delivery and more robust long-term outcomes.

Lasting change depends on people who grasp why it matters, feel motivated to get involved, know what they need to do, can perform confidently and receive support to maintain momentum. ADKAR helps leaders create each of these conditions deliberately.
