*** First Call for Project Showcases *** International Conference on Software and Systems Reuse, Product Lines, and Configuration (VARIABILITY 2026) 29 September - 2 October 2026, 5* St. Raphael Resort and Marina Limassol, Cyprus https://conf.researchr.org/home/variability-2026 The VARIABILITY conference series brings together the communities previously served by ICSR, SPLC, and VaMoS, forming a unified venue for research on variability, configuration, customization, and related disciplines in software and systems engineering. As part of this mission, VARIABILITY 2026 invites submissions to its Project Showcase Track, a forum dedicated to presenting ongoing or recently completed research projects. The track offers a stage for research teams to share their vision, goals, early outcomes, intermediate results, final achievements, and lessons learned from funded projects of all scales, including collaborative research centers, EU projects, and nationally or regionally funded initiatives. The goal is to encourage interaction, foster collaboration opportunities, and help disseminate project insights to the broader community. Objectives and Scope We welcome submissions on research projects that address reuse, product lines, and variable/configurable software systems. A list of research topics that are relevant for this track is available from the call for the papers for the VARIABILITY 2026 Research Track, at: https://conf.researchr.org/track/variability-2026/variability-2026-papers#Ca... Submissions are expected to describe ongoing or recently completed research projects within this scope. This track is not intended for publishing mature research results. Instead, it focuses on project summaries and overviews, highlighting goals, structure, challenges, insights, and project level impact. Examples of suitable submissions include: • Ongoing projects focusing on goals, challenges, methodology, or early findings • Recently completed projects summarizing outcomes, evidence, and impact • Large scale, collaborative, or multi partner efforts, where visibility and networking are beneficial • Smaller or emerging projects that would benefit from early feedback and exposure PhD thesis projects are not in scope for this track. We warmly encourage PhD candidates to submit their work to the VARIABILITY 2026 Doctoral Symposium. Submission Format • Length: 7 to 10 pages, excluding references • Format: LNCS (Springer), single blind submissions Each submission will receive feedback from three reviewers. All submissions must adhere to the LNCS (Springer) format. Please refer to the official LNCS template at https://www.springer.com/gp/computer-science/lncs/conference-proceedings-gui... . Submissions must be in PDF format and submitted via EasyChair: https://easychair.org/conferences/?conf=variability2026 (Select “Projects Showcase Track”). Presentation and Publication Accepted papers will appear in the VARIABILITY 2026 Companion Proceedings published by Springer in the LNCS series. Accepted submissions will receive a presentation slot. At least one author of each accepted paper must: • Register for the full conference, and • Present the contribution at the event Evaluation Criteria Submissions will be evaluated on: • Relevance to the conference scope • Clarity of project goals, context, and contributions • Potential for impact, collaboration, reuse, or technology transfer • Value for discussion and interaction at the conference The focus is on clarity, relevance, and value to the community rather than scientific novelty.
