Systems Thinking © 2009 - Jane Qiong Zhang and Linda Vanasupa 1 Storyboard 3 properties that determine system behavior Open vs. closed thermodynamic systems Map events Link events in causal loops Events proceed from patterns Patterns proceed from systemic structure resiliency capacity Awareness of facts: Systems exhibit certain properties that guide design decisions Main point All activity takes place within dynamic, interacting systems that cannot be separated from one another Awareness of personal role: Addressing system requires being able to visually represent the system Awareness of strategies: Changing symptoms requires changing systemic structure redundancy This work made possible in part by the National Science Foundation, DUE#0717428

7. Systems Thinking © 2009 - Jane Qiong Zhang and Linda Vanasupa Boundary system The Key System Properties Capacity- depends on placement of the system boundary and system properties Interdependency- degree of interconnectedness among the sub-systems within the system; higher interconnectedness results in less stable systems Resiliency- ability to adapt to changes in the surroundings; greater redundancy results in greater resiliency. Redundancy- the extent to which there are duplicate paths within the system to produce the same result. Surroundings 7
