Chapter 19. Modeling Matters > Managing Complexity

Managing Complexity

A model, at least any reasonable model, is simpler than the thing it models. Using a good modeling notation, the important features and characteristics of a very complex system can be represented in a relatively small and simple diagram.

Modeling gives mental leverage. If you know the symbols and the language, the model can be a way of picturing and then thinking about complex problems, especially in terms of the relationships among pieces. In code or text, relationships are implicit; a word or label here refers to a thing that is elsewhere. In most graphical models, relationships are explicit, visible as those lines and arrows connecting parts of the diagram. Good graphical models can also offer a meaningful overview of a system that would be impossible to get from reading—or writing—page after page of code.
