This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well.

All the following have a common characteristic.

This model was started at the STIA+ Conference in Seattle on April 18th by Rebecca Niles of Leverage Networks for discussion at her Open Space session. The intent is to continue that open space here in a virtual context.

Network Magic is high tech start up growing rapidly and having difficulty developing resources to respond to customer demand.

The establishment of a goal is one way to provide a basis for results thought is has its difficulties.

An introduction to what seems to be our typical approach to dealing with problems that arise unexpectedly when we're focused on dealing with other immediate issues.

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.

There are numerous influences which work against the possibility of sustainable capitalism though there are a few that might be put in place to actually support its emergence.

Insight synthesis of exchanges to better understand the basis of this decision.

Escape behavior often results in more stress than one escapes from.

Use of the latest version of the button scripts for unfolding a model or walking through the comments.

A small change in one variable can have a marked impact on multiple variables. Run the model (with height=0)  and consider the output. What happens if  you change to height=5. Run the model to find out. Was the change what you expected?

Implications of a variation between deadline and expected project completion date.

Two goal seeking structures attempting to resolve and based on the delay one may tend to settle for less. See also Archetypes.

OK, we have a problem. Yet, do we really know what the problem is? More often than not we look at the symptoms, consider them the problem and attempt to fix them. This actually dooms us to failure because they're only symptoms.

Macros are very useful for defining functions that need to be repeatedly at various places in the model.

An escalation structure results from two or more competing entities with the competition taking them to somewhere none of them want to be. See also Archetypes.

The goal seeking structure endeavors to bring a balance between a current state and a desired state. This is one of the two foundation archetypes. The other being the growth structure. See also Archetypes.

Influences which work in opposition to sustainable capitalism and influences that might work to further promote it.
