A function model, also called a functional model, is a structured representation of the functions within a modeled system or subject area. The functions it shows can be activities, actions, processes or operations. It is used in systems engineering, software engineering and computer science. Much like an activity model or a process model, it is a graphical picture of what an enterprise does within a defined scope. Its purposes are to describe the functions and processes, to help find out what information is needed, to help spot opportunities for improvement, and to give a basis for working out what products and services cost. IDEF0 is one of the function modeling methodologies built on this idea.
