Kotter's 8-step change model: the complete guide

John Kotter, then a professor at Harvard Business School, published Leading Change in 1996 after studying why most corporate transformation efforts failed. His conclusion was blunt: they failed not because the plan was wrong but because leaders underestimated how much work it takes to shift how people think and behave. The eight steps are his answer.

The eight steps

Two things are widely misunderstood. First, Kotter's original framing was sequential — the steps build on one another and skipping any one of them undermines the rest. In his later work he softened this, arguing that in fast-moving organisations the steps run concurrently and continuously. Second, step 1 is about feeling, not information. Circulating a report does not create urgency; showing a team the customer complaint queue might.

Applied in a UK workplace

Take a realistic example. A regional distribution business is moving from paper-based stock checks to a handheld scanning system. The warehouse team has done it the old way for a decade, and two of the most experienced pickers are openly sceptical.

• Urgency (1) — instead of announcing efficiency targets, the team leader shows the last quarter's stock discrepancies and the resulting late deliveries to named customers. The problem becomes concrete.
• Coalition (2) — the team leader recruits the shift supervisor, the IT support contact, and — deliberately — one of the two sceptics, who is respected on the floor.
• Vision (3) — "Every pick confirmed at the shelf, so nobody spends Friday afternoon hunting for missing stock." Short enough to repeat.
• Volunteer army (4) — three pickers volunteer to trial the scanners for a fortnight and feed back.
• Remove barriers (5) — the trial reveals the scanners lose signal in one aisle and that the pick rate target has not been adjusted for the learning curve. Both are fixed. This is the step most managers skip, and the one that decides the outcome.
• Short-term wins (6) — discrepancies in the trial aisle fall to near zero in three weeks, and this is shared with the whole shift.
• Sustain (7) — the approach is rolled out to a second site, with the trial pickers as trainers.
• Institute (8) — scanning is written into the standard operating procedure, the induction pack and the supervisor checklist.

Notice how much of the work sits in steps 4 and 5. That is Kotter's central argument.

Criticisms and limitations

This is the section that earns marks at Level 5, and the section most articles leave out.

• It is top-down. The model assumes leaders design the change and then bring people along. It has little to say about change that emerges from the front line, and critics argue it can look like sophisticated selling rather than genuine participation.
• It treats change as an episode. Eight steps with a beginning and an end fit a one-off transformation, not the continuous adaptation most organisations now live with. Kotter's own Accelerate (2014) concedes this and proposes a dual operating system in response.
• The evidence base is thin. It is drawn from Kotter's consulting observation rather than controlled research. The often-quoted "70% of change programmes fail" figure traces back to this literature and does not stand up to scrutiny.
• It assumes the change is the right one. There is no step for testing whether the vision is any good. A well-executed change in the wrong direction is still the wrong direction.
• Sequence rigidity. In practice you frequently discover barriers (step 5) while trying to build urgency (step 1), and have to loop.

A strong portfolio does not just list these criticisms — it says which of them bit in your change, and what you did about it.

How to evidence this in your ILM portfolio

Kotter maps directly onto the change units, and because ILM is assessed by portfolio you evidence it by leading or contributing to a real change, not by writing an essay about Kotter.

Level 3 — Unit 307 Managing and implementing change. Suitable evidence:

• A reflective account of a change you led, structured around the steps you used and the ones you skipped, and what happened as a result.
• Workplace documents as supporting proof: the communication you issued, the project plan, the revised procedure.
• A witness testimony from your manager or a team member confirming how you handled resistance.

Level 5 — Unit 515 Leading innovation and change, with Unit 504 Leading people and organisational culture where culture is part of the change. At Level 5 you are expected to evaluate the model, not just apply it: compare Kotter's prescription with what actually worked, and justify your adaptations.

Also useful: Unit 312 Effective communication at Level 3 or Unit 503 Managing people at Level 5, where the change involved leading people through uncertainty.

Remember that skills evidence must come from your own workplace or a realistic working environment, and must be attributable to you. See what a portfolio of evidence is and reflective account examples for the mechanics.
