A Growth and Underinvestment structure is simply an elaborated Limits to Growth structure where the growth inhibitor is part of another Balancing Loop with an external standard and some delay. The real nasty thing about this structure is that the two Balancing Loops form a single Reinforcing Loop which inhibits growth.
When we address situations we tend to do so with myopic limited awareness of the real nature of the situation and our actions tend to produce unintended consequences which make the situation worse or create other problems that have to be dealt with by us or others.
This is a definition of the Systems Thinking Interactive Learning Environment (STILE) development process which was used to create Beyond Connecting the Dots (BCtD).
This is the sample model used as a demo for enfolding and unfolding a model. This is what we had to do before the Storytelling feature was developed. Save this one for posterity!
A Tragedy of the Commons situation exists whenever two or more activities, each, which in order to produce results, rely on a shared limited resource. Results for these activities continue to develop as long as their use of the limited resource doesn't exceed the resource limit. Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished. See also Archetypes.
We often set out to solve a problem or accomplish some particular result and things seem to go as planned. As time progresses it seems that progress becomes more and more difficult, if not impossible, and things may actually become worse than when we started. When this happens it is typically a Fixes that Fail structure that's operating. See also Archetypes.
The limits to growth structure is based on the basic growth structure. And, as should be obvious, nothing grows forever as growth requires resources. Those required resources become a limits to growth. See also Archetypes.
