scope:

PURPOSE. This directive provides guidance for the systems engineering of Goddard Space Flight Center (GSFC) Missions. The intent is to outline a set of requirements that provide a consistent method for performing systems engineering across GSFC projects. The requirements for system engineering outlined in this directive are universal principles that, when followed, should result in sound systems.

APPLICABILITY. This systems engineering procedure shall be tailored and applied to all missions (e.g., projects) for which GSFC is responsible, as well as to deliverable instruments, spacecraft and other GSFC mission products. This procedure applies to all concept studies, mission formulation, and implementation subprocesses, including mission operations, decommissioning and disposal.
