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.

Enabling a Better Tomorrow is a systemic approach for developing a systemic strategy which may be employed to intervene in a current situation to effect the desired results while minimizing the likelihood of creating new problems in the process.

Bathtub model with filling control added. Running the model is essentially considered to be turning on the faucet and water will run into the bathtub until it is full.

There is much we can learn from the development of qualitative relationships models though once we begin to ask questions like how long, how much, when, etc., a qualitative most is not likely to be of much use. The following video demonstrates how, in a very simple goal-seeking structure with delay, depending on the delay, it can be almost impossible to intuit the implications of the interactions with any level of accuracy. The difficulty arises essentially from operating with outdated data. See also Archetypes.

The delays associated with adjusting the shower is a very common example of the Balancing Loop with Delay Systems Archetype. 

The Self-Referening Model is one of the four basic model forms presented by Hannon & Ruth in Dynamic Modeling.

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.

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model to investigate the implications associated with intending to save money for retirement so an amount may be withdrawn monthly for living expenses.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 simple savings account is used to demonstrate the nature of a reinforcing loop. Change the initial amount and interest rate and run the model to see the implications of changing these values.

There's actually more to filling a swimming pool with water than you might realize.

Faced with a performance gap the two most obvious responses are to work harder or work smarter. There are trade offs associated with each, some obvious, some not so obvious.

Inventory Model v2.0 adds production and order lead time. As well as the ability to keep track if parts are on order for a production run. See also: Inventory Model v3.0.

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.

Being fascinated with systemigrams I wondered if I could create them in Insight Maker.

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

This is the entry model that describes the four building blocks, Stock, Flow, Variable and LInk, used to develop models.

The three basic simulation structures.

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?

Before we can begin to sort out how to approach this situation it's appropriate to identify the relevant stakeholders and their motivations.
