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 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 SE&I Branch is part of the Research and Engineering Directorate at the NASA Dryden Flight Research Center. The goal of the SE&I Branch is to provide systems engineering services to Programs and Projects to ensure that DFRC systems are designed, built, and operated in the most cost-effective way possible. The SE&I 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 Dryden, including the Stratospheric Observatory For Infrared Astronomy ((SOFIA), Science Mission Directorate and Constellation Abort Flight Test Project (Exploration Systems Mission Directorate).
