Systems engineering is not about developing electronics, mechanical, or software designs. Systems engineering is really about four things:
In a traditional systems engineering environment, the primary medium of exchange is textual documentation, often encompassing hundreds to thousands of pages of text. Text, while wonderfully expressive, has some well-known problems for such specifications, including inherent ambiguity and difficulty in ensuring and maintaining consistency, accuracy, and the right level of fidelity.
Including model-based artifacts (UML or SysML) in the hand-off provides better understandability while simultaneously offering greater precision. It is possible to organize the systems engineering workflow to support both the systems engineering work and to support the hand-off to subsystem design teams.
