There are many applied disciplines or worldviews. For example, an engineer, a driver, a passenger, an ecologist, a tax inspector and other people interested in automobiles can look at a “car” system.
Every person has a unique worldview, that is, different roles see the physical world differently. Each role has a unique reality definition. It is obvious, that many views can fail to coincide, and different people want to change the world differently. And this is normal.
Moreover, the more people are interested in a system, the more complicated the systems is. In the modern world, one needs to regard many interests. The complexity of the world or systems is in the necessity to be able to work with numerous interests.
Each interested person is guided by his or her personal worldviews, theories, models and disciplines. All these theories not only determine a personal worldview, but also help to describe a corresponding interest as a document. For example, there is a “tax” interest in an “enterprise” system. There are accounting and taxation theories, which create a relevant description of this interest.
For there are many interests in any system, it is necessary to be able to work with these interests and theories. Currently, systems thinking is a much-in-demand work method. As a transdiscipline, systems thinking can work with various theories, disciplines and models behind any interest.
