Systems and Modeling II
In Chapter 2 it was shown that systems are objects as perceived by people (see Figure 2.1). A system was also defined as an abstraction from the world, which is in fact a model. Miller (1967) talked about formulation of chunks of information when a threshold of complexity was passed, and it was also noted in Chapter 2 that these are recursively updated as more information is received. This is conceptual/mental modeling. Much of our everyday life is concerned with this sort of activity. Despite the gross simplification, however, the process is one of reduction to a level of usefulness. It does help us to progress through everyday life; it is parsimonious.
