The deployment of Model-Based Systems Engineering (MBSE) in space projects is not straightforward. The interactions among stakeholders at various levels happen to be difficult because the tools involved are not fully interoperable. One of the key elements that would facilitate and ensure the exchange of engineering data information, is the definition of a Systems Engineering supporting infrastructure, also called System Factory, that would allow implementing this interoperability. This paper introduces the Operational Analysis, System Need Analysis and Logical Architecture of the System Factory designed following the ARCADIA method [1] and using the Capella tool. This paper is the result of the SASyF activity (“Specification and Architecture of a System Factory”).
