The Growth Archetype is a reinforcing structure which promotes exponential growth. This is one of the two foundation archetypes. The other being the goal seeking structure. Watch Video
We begin with [action] producing a [result].
That [result] promotes more of the same [action] that produced the [result].
The resultant structure is a growth structure due to the reinforcing nature of the relationships. The more it grows the faster it grows. Examples include savings account, population growth, run on a bank.
This structure may actually be virtuous or vicious depending on whether the increasing or decreasing result is desired or not.
This is the same structure implemented as a simulation model. The [factor] is simply a variable which may be varied from 0 to 1 to view the change in [results]. [action] = [factor] * [results]
With [results] = 1 and [factor] = 1 the exponential growth nature of the structure is quite evident.
If we use [action] = 0.5 you can see a substantial decline in the value of [results] at the end of the run. It's even more evident if you look at the Table values in the simulation.
Please spend some time simulating the model with different values of [results], [factor] and [Simulation Time Step] on the Settings drop down. Once you've set the parameters click Simulate. What conclusions do you come to about the relationships?
