Big Picture View of this Session
Habits of a Systems Thinker
Understanding theComplexity of Systems
Using Iceberg Model of Systems Thinking
Observes how elements within systems change over time, generating patterns and trends
Changes perspectives to increase
understanding
Identifies the circular nature of complex cause and effect relationships
Seeks to understand the big picture
Recognizes that a system’s structure generates its
behavior
Surfaces and tests assumptions
Considers an issue fully and resists the urge to
come to a quick conclusion
Habits of a Systems Thinker
Considers how mental models affect current reality and
the future
Considers both short and long-term consequences
of actions
Finds where unintended consequences emerge
Recognizes the impact of time delays when
exploring cause and effect relationships
Checks results and changes actions if needed:
“successive approximation”
Uses understanding of system structure to
identify possible leverage actions

Habits Card Exercise
Quickly make a pile of a habits cards that describe the aspects of systems thinking that you see as critical to your work.
Choose one habit from your pile and prepare to tell a short story that illustrates how you practice the habit.
Characteristics of a System
➢ System boundaries
➢ Elements or Parts
➢ Interconnections or relationships among the parts
➢ Dynamics
➢ Goal or purpose
Mental ModelsMental models are deeply ingrained assumptions, generalizations, or even pictures or images that influence how we understand the world and how we
take action. Peter Senge, The Fifth Discipline, 1990
Information &experiences around me
I notice certain information & experiences.
I add my own meaning. (cultural & personal)
I develop beliefsbased on the
meaning I add.
I do something because of my
beliefs.
R
My beliefs affect what I choose to notice in the future.
Ladder of Inference
Adapted from The Fifth Discipline Fieldbook . Last modified 5/05
Using the Ladder of Inference
• Reflection– Become more aware of your own thinking
• Inquiry– Inquire into other’s thinking and reasoning
• Advocacy– Make your thinking and reasoning more visible to
others
Behavior-over-time Graphs (BOTGs)
BOTGs show trends and patterns of behavior in a system, rather than discrete events. They measure change over time and show “what” has happened in the system as represented by the graphed component.

Feedback LoopsCausal Loop Diagrams (CLDs)
Feedback: As different parts of a system affect each other, causes become
effects which in turn become causes.
Causal Loop Diagrams (CLDs) show circular causal relationships (feedback) within a system. CLDs can show
“how” and “why” a system operates the way it does.
