Causal loop diagrams are more rigorous than rich pictures though are still only contain a very few elements with well defined rules for connecting them.

Our actions are based on our beliefs and the results of those actions are the basis for our beliefs. The difficulty we create for ourselves is that we make assumptions as to how to interpret the results we select based on our beliefs. As a result we are often operating on a flawed perspective of reality.

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.

A system is an entity that the existence of which is maintained via the mutual interaction of its parts and which demonstrates characteristics not exhibited by any of its parts.

To this point the Situation, Behavior, Model, Stakeholder and Boundary aspects of this situation have been investigated. It is now appropriate to consider the assumptions that have been made to this point and ensure we are on a solid foundation before proceeding to the Leverage and Strategy aspects are considered.

When the typical approach doesn't work we tend to rely on our tried and true problem solving approaches, which as you will see really aren't that good.

There are things we can influence and usually a broader array of things we are concerned about though can't influence. It's important to know the differerence otherwise we waste our energies trying to change things we have no influence over.

From reading Why Politics Makes Us Stupid by Ezra Klein I though I had discovered a new archetype though it's really just a simple reinforcing structure, or so it seems.

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.
