System Design Requirements

System design requirements evolve from the initial identification of a consumer/user need and are developed through the accomplishment of a feasibility analysis, the definition of system operational requirements and the maintenance concept, the development and prioritization of technical performance measures (TPMs), the accomplishment of a functional analysis, and the top-down allocation of requirements to the depth necessary. One of the objectives in system engineering is to assume a leadership role to ensure the proper and timely selection and integration of the required design disciplines, combined in such a manner as to enable the development of a system that will respond to the consumer/user need in a cost-effective manner. Inherent within the system engineering process are the requirements for reliability, maintainability, supportability, disposability, and quality. The necessity to integrate these activities into a total effective engineering design effort is a major aspect of system engineering.
