Forrester 1995 FellowArchived at the Wayback Machine See also References System Dynamics Forrester This model is presented more fully in Forrester's 1971 World Dynamics, and is notable primarily because it served as the initial basis for the World3 model used by Donella Meadows and Dennis Meadows in their popular 1972 book The Limits to Growth. ![]() The paper also gives an overview of Forrester's model of world dynamics that correlates population, food production, industrial development, pollution, availability of natural resources, and quality of life, as well as projections of those values into the future under various assumptions. ![]() The paper further suggests that measures to reduce the shortage - such as the conversion of land use from housing to industry, or an increase in real estate taxes to spur redevelopment of property - would counter-intuitively create the result desired when enacting the failed policies. an increase in the amount of low-income housing available, or a reduction in real estate taxes) counter-intuitively serve to make the situation worse by increasing the population but not the availability of jobs, so that the relative shortage increases. Systems thinking originated in 1956, when Professor Jay Forrester founded the Systems Dynamic Group at MIT's Sloan School of Management.The paper summarizes the results of a previous study on the system dynamics governing economic dynamics in urban centers, which showed 'how industry, housing, and people interact with each other as a city grows and decays.' The study's findings, presented more fully in Forrester's 1969 book Urban Dynamics, suggest that the root cause of depressed economic conditions is a significant shortage of job opportunities relative to the population level, and that the most popular solutions proposed at the time (e.g. Among the systems thinking tools are: the behavior over time (BOT) graph, which indicates the actions of one or more variables over a period of time the causal loop diagram (CLD), which illustrates the relationships between system elements the management flight simulator, which uses an interactive program to simulate the effects of management decisions and the simulation model, which simulates the interaction of system elements over time. Systems thinking uses computer simulation and a variety of diagrams and graphs to model, illustrate, and predict system behavior. Attention to that relevant feedback can allow management to look for other solutions rather than wasting resources on an approach that has been demonstrated to be counterproductive. However, in practice, that tactic might have actually slowed development in the past. For example, in project management, prevailing wisdom may prescribe the addition of workers to a project that is lagging. A balancing process is one that tends to maintain equilibrium in a particular system.Īttention to feedback is an essential component of system thinking. If reinforcement is unchecked by a balancing process, it eventually leads to collapse. A reinforcing process leads to the increase of some system component. Systems thinking can be used in any area of research and has been applied to the study of medical, environmental, political, economic, human resources, and educational systems, among many others.Īccording to systems thinking, system behavior results from the effects of reinforcing and balancing processes. The systems thinking approach contrasts with traditional analysis, which studies systems by breaking them down into their separate elements. Systems thinking is a holistic approach to analysis that focuses on the way that a system's constituent parts interrelate and how systems work over time and within the context of larger systems. ![]()
