The Iceberg Model

What are you reacting to?

3 min

Events, patterns, structures - which are you reacting to?

Most of what we react to at work is just the tip of the iceberg - the single event in front of us. But the event is rarely the whole story. Underneath it sits three more layers, each one further from view and closer to the actual cause:


  • Events – What just happened? The specific incident right in front of you.


  • Patterns – Has this happened before? What's the trend over time, once you stop looking at it as a one-off?


  • Structures – What's it about how you work - a process, a role, an incentive - that keeps producing this pattern?


  • Mental models – What belief or assumption makes that structure feel normal, or even necessary? This is the deepest layer, and usually where the real leverage sits.

When’s the best time to use this tool? 

  • When the same event keeps happening and you keep reacting to it fresh each time


  • Before you fix something, to check you're not aiming at the surface


  • When a team's behaviour only makes sense once you understand the belief behind it


  • When you're about to propose a change and want to know if it'll actually hold

How to use:

Step 01:

Name the event. Write down exactly what happened - just the facts, no interpretation yet.


Step 02:

Look for the pattern. Has this happened before? How often, and under what circumstances?


Step 03:

Ask what structure produces it.

  • What process, role, or incentive keeps generating this pattern?
  • Who's involved every time, and what are they responding to?


Step 04:

Surface the belief underneath.

What would have to be true - or seem normal - for that structure to exist unquestioned? This is the layer most people never reach, and it's usually where the real change has to happen.

Why we love it:

Most managers spend their time firefighting events, which feels productive but rarely changes anything. The Iceberg Model forces you below the surface - to the pattern, then the structure, then the belief holding it all in place - so you're solving the actual problem instead of responding to its latest symptom.

Key Takeaway

The event is just the tip. The real problem is usually a few layers down.
