Core building blocks
The foundations everything else builds on. Start here if you're new to systems thinking.

System behaviours and patterns
What systems actually do over time - the shapes you see when you step back far enough.
Systems archetypes
Recurring patterns that show up across wildly different systems. Once you can name them, you start seeing them everywhere.
Complexity and uncertainty
The terrain where traditional planning breaks down and different approaches are needed.
How to think about systems
Mental models and ways of seeing
How we think about systems - and the tools that help us see them more clearly.
Boundaries, perspectives, and power
Who gets to define the system, what's included, and whose interests are served.
Human dimensions
The psychological and cognitive aspects of working with - or against - systems.
How systems change
Resilience, adaptation, and change
How systems survive, adapt, and sometimes transform into something entirely new.
Natural and ecological metaphors
Concepts from ecology and biology that illuminate how all systems work.
Organisational and social systems
Systems thinking applied to the world of work, institutions, and collective action.
How to work with systems
Leverage and intervention
Where and how to intervene in a system to create change that sticks.
Design and intervention approaches
Practical frameworks for working with systems, not against them.
Measurement, signals, and sense
How we know what's happening in a system - and how measurement itself changes what happens.
