Documents are currently the preferred information exchange and distribution mechanism However maintenance, change traceability and cross referencing in documents is almost impossible to achieve. Thus, increasing not only the costs during the analysis stages but also the possibility of errors and use of outdated information. The aim of DGSO and related activities is to enable a transition, for all ESA missions, of the ground segment systems engineering domain to a fully model-centric approach, and for DGSO this effort is focused on the transition to a model-centric approach for the artefacts used and generated during the phase 0/A of a space mission.
