Sector Relationships

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.

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.

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.

Creating a Pulse function that has a size and duration based on an outbreak. The assumption is that there can't be an outbreak if there is an outbreak.

Leverage Point Modeling (LPM) is a demonstrated approach for improved planning and spending for Operations and Support (O&S) activities. LPM is a continuous-event simulation technique that uses the System Dynamics approach of model building. Dr. Nathaniel Mass championed the potential of LPM, and adapted it for the Department of Defense (DoD) as a tool for jumping to a higher performance curve as a means of offsetting higher costs and declining budgets. The purpose of LPM is to test policies and investments that improve mission capability for a given level of investment or funding. It is particularly used to evaluate investments in component reliability and parts availability. Ref: http://bit.ly/aT44kB

Purpose: Employ the Mono Lake model adapted from "Modeling the Environment" by Andrew Ford as a basis for developing a set of guidelines to support asynchronous multi-user model development.

Mono Lake is an ancient inland sea on the eastern side of the Sierra Nevada. From a policy point of view Mono Lake is the story of how a handful of people began a campaign to save a dying lake.

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.

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

The Exponential Growth Archetype is a reinforcing structure which promotes exponential growth. This is one of the two foundation archetypes. The other being the goal seeking structure. 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.

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.

Rich Pictures are simply pictorial representations of the relations between a number of relevant elements. The strength of rich pictures is that they're free form without any formal rules, which also tends to be the shortcoming of rich pictures.
