The concept of Systems-of-Systems (SoS) has evolved from a means to comprehend complex systems to a problem-solving paradigm based on the cooperation of multiple independent systems, and the properties that emerge from it. This transition has motivated extensive research, leading to its application in multiple engineering domains. However, multiple factors make the architecting process of systems with SoS characteristics particularly challenging. This thesis explores one in particular that has been little explored despite being linked to major integration and operational issues: the conflicts between the multiple disciplines involved in the architecting process of an SoS, in particular Systems Engineering (SE) and Software Engineering (SWE). Among other results, this thesis reveals prevalent issues related to SE-SWE collaboration in this kind of complex system. Given the lack of guidelines for addressing them, this thesis empirically identifies key 'harmonization' practices from the experience of existing long-running scientific SoS in the radio astronomy domain. On top of this, as a contribution to one of the most prominent issues identified, namely interface management, a tailored Documentation as Code (DaC) approach for managing interfaces in this context was designed in collaboration with practitioners. This was further validated with experts from multiple areas, revealing additional insights and potential extensions to other SoS domains.
