Understanding Relationship and Their Implications: The Essence of AND?

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.

The Accidental Adversaries structure represents a situation where two interacting entities which should produce growth unwittingly limit the growth of each other because of their actions to promote their own growth. 

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.

With two different ways to address a situation with one being easier and faster which do you think gets implemented? The problem is that taking the easy path makes it harder to take the longer term solution.

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.

An escalation structure results from two or more competing entities with the competition taking them to somewhere none of them want to be.

A goal seeking structure with delay can be responsible for behavior that's quite difficult to intuit.
