This model is derived from the paper "Nobody Ever Gets Credit for Fixing Problems that Never Happened: Creating and Sustaining Process Improvement" by Nelson P. Repenning and John D Sterman. See Insight 1899 for a simulation of this model.

A Growth and Underinvestment with a Drifting Standard structure is simply an elaborated Growth and Underinvestment structure where the growth inhibitor induces a decline of the standard over time. The real nasty thing about this structure is that the growth inhibitor influence sets up a Reinforcing Loop which even further promotes a drifting of the standard over time.

A Limits to Growth Systems Archetype consists of a Reinforcing Loop, the growth of which, after some success, is offset by the action of a Balancing Loop.

Introduce the concept of modeling and simulation.

As long as A and B are equally successful everything will remain stable. Though if either A or B receive more resources than the other, or A or B is more successful than the other, the imbalance will result in greater success of A or B accordingly and promote even more success of the one that demonstrates greater success.

Borrowed from STW/STiA Certification program to help develop insights regarding situations of interest to New Community Paradigms. There are a number of things should be considered to ensure a view of the relevant influences.

Analysis has served us well in developing the understanding of things, at least to a point. Though analysis will not allow us to answer the why questions about things. For that we need synthesis. One might consider analysis and synthesis two sides of a coin that one shouldn't attempt to separate.

There are limits to what one can infer from a qualitative model.

What's the real difficulty associated with managing time?

New Learning tend to reduce Outdated Thinking, Communicating & Learning though our Outdated Thinking, Communicating & Learning inhibits new learning. The question is then how do we break this cycle. Adopted from "An Introduction to Systems Thinking with STELLA" by Barry Richmond.

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. As an example, consider multiple departments with an organization using IT resources, until they've exhausted IT capacity.

It's relatively well understood that you can't be all things to all people. Somewhere one has to make choices. An Attractiveness Principle Systems Archetype is essentially a Limits to Growth Systems Archetype with multiple limits, all of which can not be addressed equally.

This is a model depicting the interactions of the Aesop's Fable "The Boy Who Cried Wolf."

This diagram presents the valid relationships between stocks, flows, and parameters. Ghosts of Stocks, Flows, and Converters can be created as needed.

Reinforcing Loop/SFD Simulation allow one to experience the explicit implications of the interactions.
