Change management is the planned, structured work of helping people and organizations understand a change, take part in it, learn what it requires, put new practices into effect, and keep them in place. A new software system, reporting policy, or operating model only delivers its intended benefits when people actually adopt it, so change management focuses on that adoption gap rather than on the announcement itself.
The UN System Staff College (UNSSC) describes the discipline in its 2025 report, State of Change Management in the UN System, as “a strategic, structured, and inclusive process that helps prepare, equip, and support individuals, teams, and organizations to successfully adapt to and sustain reforms or new ways of working.” That is a description written for the UN context rather than a universal legal or technical standard, but it captures the core idea used across most of the field.

What change management covers
The UNSSC report says change work addresses technical, cultural, and behavioral shifts, and both the human and systemic dimensions of change. The systemic side includes structures, processes, and procedures. The human side includes how people perceive, accept, and act on a change.
A concrete example helps. Suppose a finance team replaces its expense-claim system. The technical change is the new software. The behavioral change is that staff must submit receipts within a set window and use the correct categories. The systemic changes are the approval workflow, the policy that governs claims, and the reports managers use to review spending. If only the software is installed, the change has technically happened but the new way of working has not taken hold.

This is why change management is not the same as communication, though communication is part of it. The organizational side typically includes:
- aligning leaders on the purpose and expected outcomes of the change
- naming a sponsor with the authority to make decisions and remove obstacles
- communicating what is changing, why, and what it means for each group
- providing training and practice matched to the new tasks
- coordinating with the functions that make new behavior possible, such as HR, IT, and internal communications
- checking whether the new practice is being used and producing the intended result
Change management and organizational transformation
“Organizational transformation” usually refers to a broader or more consequential shift in strategy, structure, culture, technology, or operating practice. A transformation program may contain many smaller changes, each of which needs its own adoption work.
There is no single agreed scale that separates a routine change from a transformation. The UNSSC material describes both transformation and ongoing change without establishing a universal classification, so it is more useful to ask how many people are affected, how much daily work changes, and how many other initiatives are running at the same time than to decide whether a label applies.

Two levels of work: individual adoption and organization-wide implementation
Change management operates at two connected levels. The first is the individual: whether each person understands, supports, and can perform the new way of working. The second is the organization: whether leaders, structures, sequencing, and support systems move the change forward across many people and teams. Frameworks differ in which level they emphasize.

ADKAR is an individual-change model published by Prosci. Its name is an acronym for five elements. Prosci treats them as a sequence of observable outcomes that a person needs to reach before a change sticks.
| Element | What it means | Typical sign that it is missing |
|---|---|---|
| Awareness | Understanding why the change is needed | People ask why the change is happening or doubt the problem it solves |
| Desire | Willingness to participate in and support the change | People understand the change but resist, delay, or work around it |
| Knowledge | Knowing how to change, including what to do differently | People want to comply but make avoidable errors or do not know the steps |
| Ability | Putting new skills and behaviors into practice | People know the steps but cannot perform them under real working conditions |
| Reinforcement | Sustaining the new way and preventing a return to old habits | Adoption fades after launch, and people revert to previous processes |
Prosci explicitly separates ADKAR, its individual-change model, from the broader Prosci Methodology, which connects individual adoption to organizational planning, sponsorship, and support. Calling ADKAR a complete change management methodology overstates its scope.
Kotter: leading and mobilizing change across an organization
John Kotter’s Leading Change introduced the 8 Steps framework, according to Kotter’s official methodology page. The later book Accelerate moved the original linear model for episodic change toward an iterative model suited to conditions where change is constant. Kotter’s framework focuses on creating urgency, building a guiding coalition, and mobilizing people behind a shared direction, which is a different question from how one person moves from awareness to reinforcement.
How the frameworks compare
The two frameworks answer different questions, and they can be used together where they solve different problems. Neither is universally superior, and combining branded methods is not automatically necessary.
| Comparison point | ADKAR (Prosci) | Kotter 8 Steps and later work |
|---|---|---|
| Level of focus | Individuals and their adoption journey | Leadership and organization-wide mobilization |
| Scope | An individual-change model used within the wider Prosci Methodology | A broader leadership and change framework |
| Time pattern | Diagnoses where each person is in the adoption sequence | Originally staged and episodic; later work describes an iterative model for continuous change |
| Typical use | Finding the earliest unmet element and tailoring support to it | Building urgency, coalition, and direction across the organization |
Prosci’s phrase “Organizational change happens one person at a time” is a useful way to explain why individual adoption matters. It is vendor wording that introduces Prosci’s approach, not a neutral consensus statement.

How to implement a change step by step
- Clarify the case for change and the desired outcome. State what is changing, why it is changing, who is affected, and how success will be recognized. The UNSSC report recommends that sponsors set clear expectations and connect initiatives to strategic priorities.
- Map the affected groups and their capacity. Groups differ by role, location, prior experience, and exposure to other initiatives. Capacity should be checked for each group rather than assumed for the organization as a whole.
- Secure active sponsorship and coordination. The UNSSC report recommends senior sponsors who champion the discipline, invest in change capability, coordinate priorities across initiatives, and involve HR, IT, and internal communications.
- Listen and adjust support. Regular engagement, active listening, and feedback dialogues reveal barriers that a plan may not anticipate. The UNSSC recommendations call for these practices specifically.
- Build ability as well as awareness. Explain the reason for the change, then provide the knowledge and practice required, and make help available at the points where people get stuck.
- Reinforce and measure adoption. Check whether the new practices are being used and whether they produce the intended outcomes, and keep support in place where they are not. The UNSSC report recommends frameworks and metrics for measuring progress.
These steps are synthesized from the UNSSC report and the framework descriptions above. They are practical recommendations, not findings from a study that tested each step separately.
Diagnosing where a change is stalling
When adoption lags, the ADKAR elements offer a way to ask which kind of support is missing. The mapping below applies the framework as a diagnostic aid; it is not a reported finding about how often each gap occurs.
| What you observe | Earliest element to check | Likely response |
|---|---|---|
| Staff ask why the process is changing, or the old process is still defended | Awareness | Restate the problem the change solves, with examples from the affected group |
| Staff understand the change but avoid using the new tool or process | Desire | Explore concerns directly with feedback sessions, and address workload or incentive conflicts |
| Staff want to comply but make repeated errors | Knowledge | Provide clear instructions, job aids, and examples of the new steps |
| Staff know the steps but cannot complete them on real work | Ability | Offer coaching, supervised practice, and support at the point of work |
| Early adoption is good but drops after several months | Reinforcement | Build the new practice into performance expectations, reporting, and routine reviews |
What the 2025 UNSSC survey shows about change conditions
The figures below come from the UNSSC’s 2025 State of Change Management in the UN System, based on responses from 123 experienced change sponsors, change managers, and practitioners across the UN system. They describe those respondents and that institutional setting. They are not global business benchmarks.

- On average, respondents reported six simultaneous change initiatives per organization. Digital transformation, culture change, and efficiency initiatives were among the most frequently mentioned.
- 90% said the changes they were working on had a somewhat clear or very clear definition of success.
- 68% believed their organizations were at, nearing, or past change saturation.
- 87% rated their organization’s change agility as moderate or low.
- 86% of change managers believed their organization had no further capacity for change, compared with 39% of change sponsors. The gap suggests capacity should be checked across stakeholder groups rather than read from one vantage point.
- 74% said peer conversations or communities of practice were their most helpful tool for learning to manage change.
- 31% said they regularly use AI tools in change management, while 62% reported ethical or AI-bias concerns. The report also notes limited practical experience with AI and concern about preserving human relationships.
Sequencing and capacity
When several initiatives run at once, each one competes for the same people’s attention, time, and goodwill. A change that is well designed can still fail if it lands during a period when staff are already absorbing other changes. Before launching a change, check which other initiatives affect the same groups, which ones can be delayed or merged, and whether the sponsor is willing to remove work to make room. The capacity gap between managers and sponsors shown above is a reminder that people closest to the work often see saturation first.
What this means if you are affected by a change
If you work inside an organization that is changing its systems or processes, you can use the same logic as a change manager. Useful questions to ask your manager or project lead include:
- What is changing, and what will be different in my daily work?
- Why is this change happening, and what problem is it solving?
- What will I be expected to do, by when, and who will show me how?
- Where can I get help when I get stuck?
- How will the organization know whether the change is working?
Clear answers to these questions suggest that the organization is addressing awareness, knowledge, and reinforcement. Vague answers are a signal to raise the issue early, before the gap turns into repeated errors or a workaround that becomes permanent.
The limits of the evidence
The UNSSC report is the most current source here and is specific to the UN system. Its survey figures describe 123 respondents and should not be generalized to all organizations or sectors. ADKAR and the 8 Steps framework are described by their developers, and this article reports those descriptions rather than independent tests of their effectiveness. Prosci’s claims about outcomes from best-practice change management are its own and are not included, because they could not be checked against the underlying study.
