What
is Systems Dynamics?
Systems
dynamics is a modelling methodology whose power lies in understanding
complex situations through cause and effect. Invented at MIT
in 1961, it has seen much success in modelling the environment,
business dynamics and social situations. A systems dynamics model
is built by making assumptions, with their consequences explored
using a range of mathematical methods including computer simulation.
It is not always possible to predict future changes accurately
as there are too many unpredictable factors such as birth rates.
However it is possible to establish principles that govern the
way change occurs in given situations. These principles enable
the causes of growth and decline to be understood as well as
suggesting strategies to maximise growth. It is, therefore, an
ideal method for studying church growth, given the proviso that
God "continues to act the same way." He can sovereignly
change situations (represented by the parameters of the model)
at any time in ways that no model can predict.
