It's now time for the stakeholders to take the investigation resulting from leverage and craft a strategy which will address the current situation in a manner that is beneficial to the whole system.

Simple bathtub model to show the difference between Stock and Flow. Run the model with various values for filling and draining to see the implications.

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

This is an example of a very complex model though it consists only of Balancing and Reinforcing loops.

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 limits to results structure endeavors to bring a balance between a current state and a desired state though more often than not the action is limited by some constraint.  See also Archetypes.

ABM Model Test

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

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.

A basic savings account 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.

Identification of the leverage points within the Network Magic Structure is essential to developing a strategy.

Success to the successful archetype represents two reinforcing structures which may be in a delicate balance though as soon as one gains a small advantage the resource allocation favors the more successful and the result is then rapidly skewed in the direction of the more successful. See also Archetypes.

Out of Control is one of the four generic archetypes developed by Eric Wolstenholme and maps to the Fixes that Fail, Accidental Adversaries, Shifting the Burden and Addiction Systems Archetypes.

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. 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.
