Systems Thinking
Puzzles, Problems, and Messes
16 year old German Shouryya Ray solves gravitation question set by Newton
Fitness Landscapes
Mt. Fuji Fitness Landscape
Complex Systems
Complex systems are open to flows of energy, matter, and information...
What is a System?
Practical Systems Tools
Guidance for Thinking in Systems
15 year old American Jack Andraka wins Intel science fair for new pancreatic cancer test
Oregon engineers attempt to solve a mess with dynamite
Rugged Fitness Landscape
Dancing Fitness Landscape
...which flow through networks of positive and negative feedback loops...
...which are the source of:
Complexity
Interdependence between components
Nonlinear Dynamics
Output disproportional to inputs
Attractors, phase transitions, tipping points
Self-organization
Spontaneous increase in order
Adaptation
Feedback retains useful varation
Emergent properties
Whole is different from the sum of the parts
Complexity
Systems
Always think of issues in
their broader context
Don't get trapped at a single scale of analysis
Make connections across scales and across fields
Consider dynamics
not just snapshots
Harness complexity
through adaptation
Relationships are more
important than objects
Encourage
diversity
Hold ideas in
dynamic tension
Competition
Cooperation
Build models from
multiple worldviews
It's easy to get started
1. Choose a part
2. Ask what it influences
& what influences it
4. Look at the new parts
& ask the same questions
5. Repeat until
feedback loops emerge
3. Label the relationships
Iteration
Creates a reinforcing loop
Also influences
Also influences
Including marginal
perspectives

learn more?
6. Identify sources of
leverage and stability
within the system
System Archetype
Rich Picture
Systems Map
Purposeful Activity System
Four Systems Perspectives
System Dynamics
Look
between
things rather than
at
them
