Leveraging variability modeling for multi-dimensional model-driven software product lines

In order to be adopted in industrial cases, the Software Product Line paradigm must be adapted to the specific organizational context and culture. In this paper, we consider a scenario of a multinational company that would benefit from SPL. This company uses a model-based software and system development process, which allows them to build reliable and consistent systems for the defence, security, aerospace and transportation domain. Initial efforts to adopt SPL in their software production proved successful. However, they still need to leverage variability modeling to the software and system level, integrating it to their existing model-based development. Therefore, this work aims at (i) presenting an industrial scenario and identifying the main challenges to leverage variability modeling for it, (ii) outlining our point of view and perspectives on how these challenges can be addressed, and (iii) discussing the suitability of current variability modeling approaches.
