One of the keys to handling complexity is developing fitting models. A model is an abstraction of reality. It contains only those elements of reality that are necessary to describe the system of interest. For example, the earth is modeled in abstract by a globe. Water is a reality represented by the chemical model of H2O. On your desktop PC, icons model applications (MS Word, e-mail, web browser, etc.). Organization charts model corporate structures and paper planes depict jetliners.
Models may employ many ingredients. Some use mathematics, some symbols. Images, statistics, persons, and prototypes, miniatures and mock-ups all can be used as models. Models help us to comprehend, to communicate, and to handle complexity.
