We particularly encourage research papers based on industrial experience and empirical studies and which identify and structure open challenges and research questions. We are interested in all topics related to model-driven techniques in product line engineering. This includes, but is not limited to:

·       Modelling SPLs

­         Variability modelling

­         Model-based product line scoping

­         Models across the software life cycle

·       Product derivation/configuration

­         Automated and interactive techniques

­         Assembly/generation of SPL artefacts

­         Handling of non-functional properties

­         Handling large and complex SPLs

·       Visualisation and interactive techniques for large and complex SPLs

·       Feature-oriented approaches for modelling and implementation

­         Feature dependencies and feature interactions

·       Evolution and Change

­         Model maintenance (merging, conflict resolution)

­         Co-evolution of models and artefacts

·       Variability-aware techniques, e.g., for validation and verification

·       Integration of heterogeneous modelling languages and techniques

·       Runtime-variability, dynamic SPLs, variability in adaptive systems

·       Collaborative and distributed SPLs

­         Multi-stakeholder, multi-disciplinary environments

­         Multi product lines, software ecosystems

·       Non-technical issues around model based PLE

­         Management issues

­         Economic issues

­         Variability modelling “culture” and mindset of stakeholders
