Research Papers: High quality research work that uses established scientific methodologies, written using high standards of academic technical publications, i.e., original and unpublished results in all areas related to software and system product line engineering. 

Software Industry Papers: Challenges, innovations and solutions to concrete industrial applications of software product line engineering tools and methodologies. In addition, this track covers all aspects of software ecosystems from an industrial perspective. These papers should have a significant software component to the research (see the Systems Engineering track otherwise).  

Vision Papers: Papers that reach out to new communities around product lines, explore unusual interdisciplinary research, synergies with other fields, or present disruptive innovations. These papers should not be traditional SPLC research papers in a shorter form. 

Systems Engineering Papers: The track solicits both research-oriented and/or industry-oriented papers, which are explicitly aimed at product lines residing primarily in the Systems Engineering space. Specifically, this track is for papers addressing product line engineering where the focus extends beyond software to other lifecycle phases (design, testing, mechanical, electrical, operations, portfolio management, manufacturing, systems modeling, simulation, etc.) and/or concerns across all stakeholder organizations. Industry or research papers focusing primarily on software product lines should be submitted to the traditional industry and research tracks.
