The Methodology of Systems Engineering

It is well known that the amount of contents related to the Systems Engineering often makes confused the users about their suitable exploitation in a linear product development process. Therefore, in this first technical chapter, some basic concepts are defined and some typical models of product development are shown. They are compared and distinguished from some architecture frameworks currently applied to define the system capabilities and some crucial views. A sketch of the main steps of the Systems Engineering implementation is finally drawn, together with a list of some proprietary approaches proposed by societies, companies and software vendors for its straight deployment. Tools and languages are even described, together with some engineering methods and the SysML language is used as a relevant example to describe the main diagrams applied in functional modeling.
