Eight ascending steps with a flag at the top and one step incomplete

TL;DR

Is Kotter's 8-Step Change Model Still Relevant?

  • The 8 steps remain the most widely used change framework in business, and the research supports each step individually.
  • No study has ever validated the model as a whole, and its three structural gaps - linearity, top-down bias, and the missing individual dimension - are well documented.
  • Kotter closed the first gap himself: since 2014 the steps have been concurrent accelerators, not a sequence.
  • The remaining gap is measurement. The model tells you what to do; it has never been able to read the culture you are doing it to. That is what has changed.

Ask a room of managers to name a change model and you will get one answer before any other: Kotter. The 8 steps have been the default grammar of organisational change since 1995, taught on every MBA and stencilled into a thousand transformation decks. I studied under John Kotter at Harvard, and the first thing worth saying about the model is that it earned its place - it was built on a blunt observation that has never stopped being true. Most change efforts fail, and they fail in predictable ways at predictable stages.

The second thing worth saying is that the model is thirty years old, the academic record on it is mixed in ways that matter, and Kotter himself has revised it more thoroughly than most of the people still using the 1995 version. So the question deserves a straight answer rather than loyalty in either direction.

What the model actually says

What is Kotter's 8-Step Change Model?

Kotter's 8-Step Change Model is a framework for leading organisational change, first published in Harvard Business Review in 1995 and expanded in the 1996 book Leading Change. The steps are: create a sense of urgency, form a powerful coalition, create a vision for change, communicate the vision, remove obstacles, generate short-term wins, build on the change, and anchor the changes in culture. Kotter derived the sequence from studying over 100 companies attempting major transformation, arguing that most failures happen in predictable ways at predictable stages.

What made the original Harvard Business Review article land was not the list but the failure analysis behind it. Each step exists because Kotter watched transformations die there. Urgency fails when fewer than three quarters of management genuinely believe the status quo is unacceptable. Vision fails when it takes thirty minutes to explain - his test was five minutes or less. Consolidation fails when victory is declared early: in eight of ten re-engineering efforts he studied, the useful changes had dissolved within two years of the celebration.

Those thresholds are the part of the model that still reads as field notes rather than theory, and they are the part practitioners quietly rely on.

Each step exists because Kotter watched transformations die there.

What the evidence supports - and what it doesn't

What are the criticisms of Kotter's 8-Step Change Model?

Three criticisms recur in the academic literature. First, the model was presented as a strict sequence, but no study has validated that the steps must run in order - and practice shows they overlap. Second, it assumes top-down, hierarchical governance, which fits fewer organisations every year. Third, it operates at the organisational level while, as Kotter himself acknowledged in 2002, the core problem of change is changing the behaviour of individual people. A separate methodological critique notes that the original claim of studying over 100 companies was never accompanied by a documented method or sample.

The most thorough review remains Appelbaum and colleagues' 2012 study, which went through fifteen years of research step by step. Its conclusion cuts both ways. For each individual step there is supporting evidence: urgency aligns with the change-readiness research of Armenakis; coalition strength correlates with position power; communication quality predicts employee satisfaction through restructuring; short-term wins measurably build momentum. But no study validates the model as a whole, and the weakest evidence sits exactly where Kotter said the stakes were highest - step 8, anchoring change in culture.

Mark Hughes' 2016 critique added the methodological point: the "over 100 companies" behind the original claims were never described - no sample, no protocol, no data anyone could re-examine. That does not make the model wrong. It makes it what it honestly is: a thinking tool distilled from an unusually good observer, not a validated predictive instrument. The difference matters when a board treats the eight steps as a guarantee.

Kotter or Lewin?

What are the key differences between Kotter's 8-Step Change Model and Lewin's change management model?

Lewin's model has three phases - unfreeze, change, refreeze - and describes the psychological arc of any change: loosening the current state, moving, then stabilising the new state. Kotter's model has eight steps and is a leadership playbook: it tells executives what to do, in what order, to drive a large transformation. Lewin is simpler and more general; Kotter is more prescriptive and more operational. They are compatible - Kotter's steps 1 to 4 broadly unfreeze, 5 to 7 move, and 8 refreezes - but neither model measures whether the culture in front of you is ready for any of it.

The comparison is worth a moment because it clarifies what kind of thing Kotter's model is. Lewin gave the field its physics; Kotter gave it an operating manual. And the last clause of the answer above is the point this article keeps returning to: both frameworks describe the change, and neither can see the culture it lands on.

Kotter revised it himself

The criticism the field spent two decades making - that real change does not run in a neat sequence - was eventually conceded by the one person with the authority to fix it. In Accelerate (2014), Kotter re-cast the eight steps as eight concurrent accelerators, running continuously inside a "dual operating system": the hierarchy manages the routine business while a volunteer network - five to ten per cent of the workforce is enough - moves at speed on the change itself. Urgency is no longer a phase you complete; it is a condition you maintain.

His 2021 book Change went further, grounding the framework in neuroscience: a workforce operating in threat-response mode - the survive channel - cannot do the creative, collaborative work that transformation requires, however precisely the eight steps are executed above their heads. It is a striking place for the model to have arrived, because it concedes the point Kotter first made in 2002: the core problems of change are never really strategy, structure or systems. They are changing the behaviour of people.

The model tells a leadership team what to do. It has never been able to tell them what they are doing it to.

The gap that remains is measurement

Follow the model's own evolution to its logical end and you arrive at a question the framework has never answered. If change fails at urgency because the culture is comfortable, at coalition because trust forms slowly, at vision because the organisation mistakes a forty-page strategy document for a story - then the decisive variable is not the playbook. It is the culture the playbook lands on. The model tells a leadership team what to do. It has never been able to tell them what they are doing it to.

That is no longer an unmeasurable thing. Culture is the collective language and behaviour of an organisation's people, and behaviour can be mapped: aggregate the working preferences of everyone in the organisation and you get a measured picture - across six dimensions - of exactly the terrain the eight steps must cross. Whether urgency will find receptors or complacency. Whether a coalition will form in weeks or quarters. Whether "short-term win" means ninety days or eighteen months in this culture's definition of finished. Each of the eight steps, read against real preference data rather than assumed - which is the subject of the readiness article in this series.

Used that way, the three known weaknesses close. Linearity: a measured culture shows which steps are ready now, in any order. Top-down bias: the data comes from the whole population, not the org chart. The missing individual dimension: the map is built from nothing but individuals, one ten-minute survey at a time.

So - still relevant?

Is Kotter's model still relevant?

Yes, used honestly. Reviews of the research find supporting evidence for each individual step - urgency, coalition, vision, communication, obstacle removal, quick wins, consolidation and anchoring all correlate with change success in separate studies. What was never validated is the model as a whole, and its author has moved on from the strict sequence himself: since 2014 Kotter has presented the steps as concurrent accelerators rather than a linear checklist. Treat the 8 steps as eight diagnostic lenses rather than a recipe and they remain among the most useful tools in change management.

The honest position, then, is neither reverence nor dismissal. The 8 steps are the best-evidenced description we have of where change efforts die. They are not a sequence, they are not a guarantee, and they were never a measurement. Use them as eight questions to ask of a culture you can actually see - and the thirty-year-old model becomes sharper than it has ever been. The framework was always sound. What it was waiting for was the data.

The companion pieces: why culture is measurable at all is in why culture can be mapped; the canvas it is measured on is the six dimensions; what readiness means and how to assess it is in what is change readiness. The instrument is Sariio AI.
