Why Change Models Matter
(and Why Most People Ignore Them)
Change is not the problem. Poorly managed change is.
Most organisations jump straight into implementation. New system, new process, new structure. Then they wonder why things fall apart halfway through.
That is where change management models come in. They are not theory for the sake of theory. They are practical tools that help you guide people from where they are today to where you need them to be.
At their core, these models help you:
- Reduce resistance
- Improve communication
- Structure your approach
- Increase the chances of success
They do not guarantee success. But not using one almost guarantees problems.
1. Lewin’s Change Model – Keep It Simple
Three stages:
- Unfreeze
- Change
- Refreeze
In simple terms: You prepare people, you implement the change, and then you lock it in.
The strength of this model is its simplicity. It is easy to understand and works well for smaller or more contained changes.
The weakness? Real life is rarely that neat. Change is often messy and ongoing.
2. Kotter’s 8-Step Model – The Structured Approach
It walks you through change step by step:
- Create urgency
- Build a guiding team
- Set a clear vision
- Communicate it
- Remove barriers
- Create quick wins
- Keep momentum
- Make it stick
This model gives leaders a clear playbook but can feel heavy if applied too rigidly.
3. ADKAR – Focus on the Individual
ADKAR focuses on individual change:
- Awareness
- Desire
- Knowledge
- Ability
- Reinforcement
It helps identify where people are getting stuck and why.
4. The Change Curve – The Human Side of Change
People go through emotional stages:
- Shock
- Resistance
- Frustration
- Acceptance
- Commitment
Understanding this helps you respond properly instead of reacting emotionally.
5. McKinsey 7S – The Big Picture View
It looks at:
- Strategy
- Structure
- Systems
- Shared values
- Skills
- Style
- Staff
It ensures everything is aligned during change.
6. Bridges Transition Model – Change vs Transition
Three phases:
- Ending
- Neutral zone
- New beginning
If people have not let go of the old, they will not commit to the new.
7. Nudge Theory – Small Changes, Big Impact
It influences behaviour subtly:
- Change defaults
- Simplify decisions
- Guide behaviour
Useful for behavioural and cultural change.
So… Which Model Should You Use?
There is no single best model.
Most change managers mix approaches depending on the situation.
Models are tools, not rules.
Final Thought
Change will happen whether you manage it or not.
Unmanaged change creates chaos. Managed change creates opportunity.
