Every system has a goal. We know this and we help an organization find the correct measurements to move it ever closer to its goal. However, each system is composed of subsystems. Sometimes these are obvious and self-imposed, such as departments of a firm or classes in a school. Sometimes they are less obvious such as systems of political allegiance within the firm or ethnic groups within the school. Conversely, each system is always just a subsystem of some supersystem: the firm is part of a supply chain and the school is part of a community. We happily use the phrase "the system as a whole" but, in reality, there is no such thing.
How do the goals of each of these systems, subsystems and supersystems interact? Classically, we know that measurements applied to the departments of a firm often move the firm itself away from its goal. And that's because each department's goal does not recognise the goal of the supersystem. To what extent does this happen? To what extent is it the case that a subsystem's goal is always in conflict with it's supersystem's goal? Considering a system as a network of dependencies, graph theory tells us that there are a great many possible subsystems (subgraphs) of the main system. To what extent, in reality, do each of those subgraphs represent a "real" subsystem with its own goal? At what point do we stop moving upwards, looking at higher and higher level supersystems and say: "these are separate systems for which it is not worth looking for a common goal"?
Each system is made of individuals working. Each of these people is a valid system with its own goal. If we come up with a framework for examining goal-interaction between systems and their components then it should be able to model the way people interact with each other either in the effort to reach a common goal or in the effort to attain their goal at the expense of others' goals or of the goal of the society or organization they belong to.
