    It is common throughout industry to see digital transformation through model-based initiatives (MBIs). The prevalence of models can now be seen across systems engineering (SE) activities, throughout the life-cycle. So why is it challenging to understand the landscape of SE and Architecture in the context of MBIs?
    The authors analysed key concepts and relationships of systems life-cycle activities (ISO/IEC/IEEE 15288) and architecture descriptions (ISO/IEC/IEEE 42010). Although base level activities and approaches could be generalised, there are were issues with common understanding.
    A conceptual model has been produced, describing aspects of the landscape for SE life-cycle processes and MBIs. The importance of architecture description languages and their associated metamodels is also discussed in terms of how these contribute as enablers towards model-based transformations.
    This paper shows how an increased use of robust ontologies and metamodels, and their integration with underlying SE life-cycle processes and models, can contribute to improved common understanding when transitioning to a model-based organisation.
    An INCOSE UK joint workstream was formed to understand the relationship between Architecture and Model-based Systems Engineering (MBSE) and explore areas of common interest. One of the themes is the Landscape of Architecture and MBSE, which this paper has been produced from. The purposes of the theme are to: identify key relationships and dependencies between architecture and MBSE, provide a map of the landscape, understand where architecture and MBSE converge and diverge, and to support the other themes. To establish common ground, the authors represented key terminology and relationships for systems life-cycle activities and architecture descriptions (ADs) as conceptual models. These conceptual models were elaborated on to capture key aspects of the Systems Engineering (SE) and Architecture landscape (the Landscape) and the relationship with model-based initiatives (MBIs). This paper discusses the team’s challenges with modelling the architecture of the Landscape and reflects on the need for integrating MBI-related systems life-cycle processes (SLCPs) into the organisation when transitioning to a model-based organisation.
