While these pictures represent very different things there is a common essence.

A model to use to demonstrate scenarios using button scripts.

This is a simplification of the Austerity vs Prosperity model in the hope that it will be easier to understand.

The boundary defines the extent of the system.

Examples of reinforcing and balancing loops enhanced with images to maybe them more visually engaging.

Population Growth in an Agrarian Society with the addition of agriculture.

Storytelling allows you to build a display sequence for an insight so it can be unfolded to tell the story of the model. You can sequence primitive visibility, messages and javascript actions to unfold the story of the model.

Often times there are a number of parameters in a model you want to set to specific values and run the model to demonstrate a particular behavior. When there are several variables involved remembering the setup is often difficult and takes time. And can you demonstrate the behavior when you're not there? Developing scenarios with Button scripts is a quick way to overcome these difficulties.

A spatially aware, agent based model of disease spread. There are three classes of people: susceptible (healthy), infected (sick and infectious), and recovered (healthy and temporarily immune).

There are about fifteen known archetypes with an interesting set of relationships among them.

This is the demo project used for the 19.05.21 introduction to Insight Maker Simulation internet session.

Demo of changing vector length on the fly.

Investigations into the relationships responsible for the success and failure of nations. This investigation was prompted after reading numerous references on the subject and perceiving that *Why Nations Fail: The Origins of Power, Prosperity, and Poverty* by Acemoglu and Robinson seem to make a great deal of sense.

Consider the following "Sustaining the Forest" model intended to provide another example of how unexpected the behavior of a web of extended interactions can be.

This model represents an elaboration of the Savings Account model to investigate the implications associated with intending to save money for retirement so an amount may be withdrawn monthly for living expenses.

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.

This is the model of the collaborative model development process which is being developed in a collaborative method to help understand what guidelines might be developed to aid in the model development.

Once the strategy has been developed it's up to the Stakeholders who own the segments of the revised model to implement it so a new pattern of behavior is created thus effecting the desired situation.

Use a bathtub model to investigate the manner in which inflows and outflows govern the quantity of a stock. Extend the structure to create and investigate the relationships of a goal seeking balancing loop.

A map of the elements associated with Systems Thinking as defined by different sources.

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.

The strategy is actually a set of structural changes that have to be made to the relationships that cause the future to be different than the past.
