SYSTEM: Many abstract definitions-classifications of systems,e.g.:physical-human designed, biological, social, political,open, closed, et al. For simplification purposes, I will only address physical-human designed systems such as: a hi-fi audio system, car, airplane, C5i (command, control, communications, computer, collaboration/cyber, intelligence).
A system is an integrated set of interacting subsystems/components working together to achieve an overall system objective function. It consist of: hardware, software (in some cases),facilities,personnel, and operations and maintenance data/procedures. The Mission Requirements, Overall System Level Requirements (e.g., availibility/reliability/maintainability, etc), Primary Design Requirements,Interface Requirements, Environmental Requirements, Logistics Support, and Test and Evaluation Requirements need to specified in the system specification. The system specification tree becomes part of the Program Work Breakdown Structure. These system requirements are allocated to major functional subsystem requirements and on down the line to to lower levels of system indenture, including identifying critical engineering/logistics risks components and back requirements.
Given the above, what is the System Objective Function (SOF) of a car or cyberpeacefare ?
(Answers: Car - transport people and baggage/things. Cyberpeacefare - ?
