Systems Engineering and Integration
Systems Engineering and Integration (SE&I) is a disciplined approach for the definition, implementation, integration, and operations of a system (product or service). Emphasis is placed on the satisfaction of stakeholder functional, physical, and operational performance requirements: these include intended use environments, intended life cycle, and cost and schedule constraints. SE&I includes the engineering activities and technical management activities related to the above definition considering the interface relationships across all elements of the system, other systems, or as a part of a larger system.
