Interface Management for a NASA Flight Project Using Model Based Systems Engineering (MBSE)
The goal of interface management is to identify, define, control, and verify interfaces; ensure compatibility; provide an efficient system development; be on time and within budget; while meeting stakeholder requirements. This paper will present a successful seven step approach to interface management used in several NASA flight projects. The seven step approach using Model Based Systems Engineering will be illustrated by interface examples from the Materials International Space Station Experiment X (MISSE X) project. The MISSE X was being developed as an International Space Station (ISS) external platform for space environmental studies, designed to advance the technology readiness of materials and devices critical for future space exploration. Emphasis will be given to best practices covering key areas such as interface definition, writing good interface requirements, utilizing interface working groups, developing and controlling interface documents, handling interface agreements, the use of shadow documents, the importance of interface requirement ownership, interface verification, and product transition.
