To develop insights regarding a situation of interest there are a number of things should be considered to ensure a view of the relevant influences.

A Tragedy of the Commons situation exists whenever two or more activities, each, which in order to produce results, rely on a shared limited resource. Results for these activities continue to develop as long as their use of the limited resource doesn't exceed the resource limit. Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished. As an example, consider multiple departments with an organization using IT resources, until they've exhausted IT capacity.

This is a model depicting the interactions of the Aesop's Fable "The Boy Who Cried Wolf."

Based on a sound realization of reality we need an effective approach to dealing with situations which promotes the requisite understanding to develop a strategy that deals appropriately with the situation. A strategy which also is explicitly designed to minimize unintended consequences and puts in place responses to them should they arise.

A Limits to Growth Systems Archetype consists of a Reinforcing Loop, the growth of which, after some success, is offset by the action of a Balancing Loop.

If we pay close attention to our actions and the typical outcomes of those actions it would be evident that there are frequently occurring patterns that develop. And there is a relation between the patterns.

As long as A and B are equally successful everything will remain stable. Though if either A or B receive more resources than the other, or A or B is more successful than the other, the imbalance will result in greater success of A or B accordingly and promote even more success of the one that demonstrates greater success.

Part 1 demonstrates Picture primitives and Links to create representations of interactions. These are made visually attractive because the Picture primitives are overlayed with images.

When endeavoring to develop an understanding of the nature of something it is generally useful to create a model of some type to aid in surfacing that understanding.

This fixes that fail diagram describes how people often address symptoms, but not fundamental causes.  Poke yoke is a design principle that operates in one of two ways.  One is to prevent the defect from occurring, which addresses the source.  This is ideal because there are no defective products to scrap or rework.

The other is one that prevents defective work-in-process from being passed on to the next stage.  This does not prevent the defect from occurring.  There is still the scrap and rework, but it prevents the product from reaching the customer.
