Systems Engineering and Integration (SE&I) is part of the Research and Engineering Directorate at NASA’s Armstrong Flight Research Center in Edwards, California. SE&I is a disciplined approach for the definition, implementation, integration, and operations of a system (product or service). Emphasis is on the satisfaction of stakeholder functional, physical, and operational performance requirements in the intended use environments over its planned life cycle within 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.

The goal of Armstrong’s branch is to provide systems engineering services to programs and projects to ensure that Armstrong systems are designed, built, and operated in the most cost-effective way possible. The branch provides high-quality systems engineering expertise, and supporting products and services required of successful programs and projects. The branch primarily supports large and complex flight and space projects at Armstrong, including NASA’s Science Mission Directorate and space exploration missions.
