Representing the characteristics of modeled processes

In modeling a system which exhibits some dynamic behavior, representation of the processes that originate the dynamic changes in the system is elementary to understanding how the system works, and also to having an accurate and meaningful model of that system. In order to model such processes, the defining characteristics of the processes prove useful in their composition and presentation. A minimal subset of those characteristics are presented here, with consideration for potential variations among them, and also consideration of possible implications that such modeling may lead to - understanding of system behavior that can be represented with such modeling, that may not be possible without these characteristics being exhibited.
