Skip a Step

John Kotter studied over a hundred transformations and found the same thing every time: they don't fail at random. They fail at the exact step somebody skipped — and the bill arrives months later, when it's expensive. You have 12 tokens of leadership attention and eight steps that each want three. You can't fund everything. Choose what to skip, run 18 months, and see where it bites.

The model

Eight steps, because eight ways to fail

Kotter's model wasn't derived from watching transformations succeed. It came from watching more than a hundred of them fail — first in the 1995 Harvard Business Review article "Leading Change: Why Transformation Efforts Fail," then in the book Leading Change. Each step exists because he kept finding its absence in the wreckage. That's why the steps are sequential: each failure mode is the absence of a step, and each step builds the platform the next one stands on. Skip one and the program doesn't fail immediately — it fails later, at the month where that step's work was supposed to be holding the weight.

Create urgency

Make the case for change vivid enough that people clear their calendars. Kotter's bar: about 75% of management genuinely convinced the status quo is more dangerous than the change.

Error #1: allowing too much complacency.

Build a guiding coalition

Assemble a group with enough position power, expertise, and credibility to lead the change — and get them working as a team, not a committee.

Error #2: failing to create a powerful enough guiding coalition.

Form a vision & strategy

A picture of the future clear enough to direct a thousand small decisions. Kotter's test: if you can't communicate it in five minutes and get a reaction, you're not done.

Error #3: underestimating the power of vision.

Communicate the vision (×10)

Use every channel, constantly — and behave consistently with the message. What leaders do is the loudest channel of all.

Error #4: undercommunicating the vision by a factor of ten.

Remove obstacles

Change the structures, systems, and incentives that still reward the old way — and confront the managers who undercut the change. Empowerment is mostly subtraction.

Error #5: permitting obstacles to block the new vision.

Generate short-term wins

Plan for visible wins in the first year — don't just hope for them. Wins are the evidence that keeps sponsors funded and skeptics quiet.

Error #6: failing to create short-term wins.

Consolidate gains

Use the credibility of early wins to tackle the bigger, structural changes. Resistance doesn't disappear when you celebrate — it waits.

Error #7: declaring victory too soon.

Anchor changes in culture

Show people how the new behaviours produced the results, and make sure hiring, promotion, and succession carry the change forward. Culture comes last, not first.

Error #8: neglecting to anchor changes in the culture.

Why "communicate ×10"

Of all eight errors, Kotter put a number on exactly one. Studying failed transformations, he found the vision was routinely undercommunicated by a factor of ten — and in Leading Change he sharpened it further: often by a factor of 100, even 1,000. The arithmetic is brutal. In three months, an employee might receive millions of words of corporate communication — emails, meetings, dashboards, hallway chatter. The transformation typically gets a kickoff, a few emails, and a slide at the town hall: a rounding error of the total. Everything else the company says is, implicitly, a message that nothing has changed.

That's why one great speech does nothing, and why in the simulator a weak step 4 hands the narrative to the grapevine. The vacuum always gets filled — the only question is by whom. Kotter's fix isn't louder announcements; it's every channel, every week, and leaders whose behaviour matches the words. Repetition isn't nagging. Repetition is the message.

Honest caveats

What this model is — and isn't

Kotter's eight steps are the most useful checklist ever written for leaders driving change. They are not the whole story, and the simulator inherits their blind spots. Use the model with its limits in view:

It's a top-down model

The eight steps describe change as something leadership does to an organisation. That's often true — and it systematically underweights change that bubbles up from teams, customers, and the people closest to the work.

Pair it with a person-level model

Kotter tracks the program; models like ADKAR (awareness, desire, knowledge, ability, reinforcement) track each individual. An organisation "at step 6" still contains people at every stage — both lenses, or you're flying half-blind.

Expect a loop, not a line

Real change iterates: steps overlap, urgency needs re-creating, visions get revised mid-flight. Kotter himself later reframed the steps as continuous "accelerators" run by a volunteer army, not a one-pass sequence. The order still matters — as dependencies, not as a calendar.

The simulator is a caricature

Real organisations are noisier, slower, and more surprising than any deterministic curve. What the simulator preserves is the part Kotter's evidence supports: skipped steps send a bill, and the bill arrives late. Treat the numbers as story, not forecast.

Here's the uncomfortable version of the exercise you just ran: your organisation already has an allocation. It's visible in the last three change programs — the step that never gets funded, the failure mode that keeps showing up with different project names on it.

Which step does your organisation habitually skip? If you can name it — and most leaders can, instantly — you already know where the next transformation will bite. Fund that step first. Skipping it was never faster.
