Common Terms[edit]

Boundary Object[edit]

  • A tangible representation (e.g. diagram with few words) to illustrate key concepts, actions and the relationships between them, which are accessible and modifiable by all participants (Black & Andersen, 2012)

Community[edit]

  • There are many definitions of the term "community" (e.g. geographical, by association). In System Dynamics practice, "how we define 'community' determines who is is involved, how the issues get framed, who the stakeholders are, how we understand the politics and power, and even what language we use". The process of defining a community is a scientific act. (Hovman, 2014, p7.)

Community based system dynamics[edit]

  • A participatory method for involving communities in the process of understanding and changing systems from the endogenous or feedback perspective of system dynamics (Richardson, 2011; Sterman, 2000; Forrester, 1990; as cited in Hovmand, 2014, p.1)

Decision rules[edit]

  • The policies and protocols specifying how the decision maker processes available information, and thereby takes action (Sterman, 2000)
  • "A decision rule specifies which information to take account of, and how to combine the information to arrive at a decision." (Hines & House, 2001)

Dynamic hypothesis[edit]

  • A statement of belief that a particular articulation or model of a system can generate the behavior described in the reference mode. (Hovmand, Sato, Kuhlberg & Chung, 2015)

Feedback Loop[edit]

  • A closed loop structure that brings results from past action of the system back to control future action (Forrester, 1990)

Group Model Building[edit]

  • A process of involving multiple stakeholders that are central to a project in developing an informal or formal model (Hovmand, 2014)
  • The process aims to create shared insights, consensus, and motivation for implementing the results (Hovmand, 2014)

System Dynamics[edit]

  • System dynamics is the use of informal maps and formal models with computer simulation to uncover and understand endogenous sources of system behavior (Richardson, 2011)
