Evaluating and comparing MBSE methodologies for practitioners

The objective of Model-Based System Engineering (MBSE) is to provide the right tools to create and manage all life-cycle information in a pragmatic, concise, consistent and traceable way across the numerous perspectives and architectural levels. Its practical use, however, is currently impeded by a universal lack of experience and integration with development processes. Interested engineers therefore find it difficult to select the methodology best suited for their particular context. This paper proposes a Framework for the Evaluation of MBSE Methodologies for Practitioners (FEMMP) based on a catalogue of standard criteria to assess the practical use of the available methodologies, which are evaluated using a standard case study. The paper illustrates the evaluation process comparing the authors' own methodologies: SYSMOD+ and the MDDM.
