At the 15th System Analysis and Modelling Conference (SAM) in October 2023, a panel session was dedicated to the discussion of the past, present, and the future of Model-Driven Development (MDD). The session focused on the themes history, impact, lessons learned, and barriers to the adoption of MDD. In the context of history and impact, the results of the Norwegian national R&D project “Support to Integrated System Development” (SISU) were discussed, as well as recent development approaches akin to MDD. SISU focused on MDD based on the Specification and Description Language (SDL), a modeling language standardized by the International Telecommunication Union (ITU). The panelists agreed that the quality of the systems produced within SISU was usually very high, since SDL and the concepts used in a model match reality well and make it therefore easier to comprehend. Nevertheless, the adoption of MDD did not progress as expected after project completion. The discussion on barriers to MDD revealed key challenges in two perspectives: users experience and tools support. Besides some lessons learned, this paper presents a number of recommendations, that might help to address the mentioned challenges leading towards a more prominent use of MDD in software engineering in the future.
