System Engineering Schema Overview Color Code Physical Element Interface Element FunctionalElement Requirement Element decomposed by basisof Function Exit Requirement exits by refined by inputs / outputs / triggered by captures / consumes / produces specifies Selected Classes Item Resource decomposed by performs transfers connected to / thru Component Link built from joins & joins thru comprised of Interface This diagram reflects the heart of the systems engineering schema. Additional classes and relationships exist to capture issues, risks, test & evaluation material, and much more.
