*** Last Call for Papers (Research/Industry) *** 19th European Conference on Software Architecture (ECSA 2025) September 15-19, 2025, 5* St. Raphael Resort and Marina, Limassol, Cyprus https://conf.researchr.org/home/ecsa-2025 (*** Proceedings to be published by Springer in LNCS ***) The European Conference on Software Architecture (ECSA) is the premier European software architecture conference, providing researchers, practitioners, and educators with a platform to present and discuss the most recent, innovative, and significant findings and experiences in the field of software architecture research and practice. The 19th European Conference on Software Architecture (ECSA 2025) will be held from September 15 to 19, 2025. ECSA 2025 is planned as an in-person conference taking place in the beautiful city of Limassol (Cyprus). SCOPE The theme for ECSA 2025 is “impactful software architecture”. The software architecture discipline has had a critical role in shaping robust, scalable, and maintainable systems. We are interested in learning about software architecture principles and practices, emergence trends and case studies highlighting strategic architectural choices that can lead to enhanced performance, improved collaboration, and long-term sustainability. The overarching question is how these architectural principles and practices, both well-established and emerging, are making an impact in real-world systems, and how that impact is being felt across various domains, from enterprise systems to more novel areas like, e.g., AI-driven or autonomous applications? The Program Committee of the 19th European Conference on Software Architecture seeks submissions of original and unpublished high-quality papers describing fundamental and applied research; new methods, approaches, and processes; novel applications; education and training in software architecture; and experience reports on all topics related to software architecture. We particularly encourage papers that demonstrate that diversity in gender, culture, religion, country, etc. are key factors for success and innovation in software architecture. Topics of interest include, but are not limited to: • Foundational principles of software architecture • Relationship of requirements engineering and software architecture • Quality attributes and software architectures • Architecture practices for secure, explainable, and trustworthy software • Architecture design and analysis • Architecture description languages and meta-models • Architecture verification and validation • Management of architectural knowledge, decisions, and rationale • Architecture patterns, styles, and tactics; reference architectures • Architecture viewpoints and views • Architecture conformance • Software architecture virtualization and visualization • Architecture-centric process models and frameworks • Software architecture and agile, incremental, iterative, and continuous development • Component-based models and deployment; middleware • Software architecture and system architecture • Software tools and environments for architecture-centric software engineering • Ethics, cultural, economic, business, social, human, and managerial aspects of software architecture • Architecture and technical debt • Architecting for sustainable and environment friendly systems • Applying AI and LLMs in software architecture and architecting for AI and LLM intensive systems • Software architecture education • Cross-disciplinary approaches to software architecture • Architectures for reconfigurable and self-adaptive systems • Architectural concerns of autonomic systems • Software architecture applied to new and emerging areas, such as the cloud/edge, big data, blockchain, cyber-physical systems, IoT, autonomous systems, systems-of-systems, energy- aware software, quantum computing, AI-enabled systems • Empirical studies, systematic literature reviews, and mapping studies in software architecture • Diversity, equity, and inclusion in activities related to software architecture RESEARCH PAPERS ECSA 2025 seeks four types of papers for the research track: • Research papers (max. 16 pages in LNCS style) which describe novel contributions to software architecture research (submissions should cover work that has a sound scientific/technological basis and has been validated) • Education and training papers (max. 16 pages in LNCS style) that address methodologies, experiences and best practices for teaching and training software architecture • Experience reports (max. 16 pages in LNCS style) that cover innovative implementations, novel applications, insightful performance results and experience in applying software architecture research advances to practical situations and systems • Short papers (max. 8 pages in LNCS style) that present novel and preliminary work-in- progress or challenges in a topic of software architecture research, education, and training. Submissions must have a sound basis, but not necessarily be validated in full. All submitted papers will undergo a rigorous double-blind peer review process. Papers will be selected based on originality, quality, soundness, and relevance. All contributions must be original, not published, accepted, or submitted for publication elsewhere. Contravention of this concurrent submission policy will be deemed a serious breach of ethics, and appropriate action will be taken in all such cases. Plagiarism checking will be conducted and any paper reporting more than a 20% match with published work will be desk-rejected. To note is that research papers, education and training papers, and experience reports that are rejected in their categories may be re-evaluated as short papers only if the committee decides on rejection of the full paper on the basis that it presents preliminary work. The research track of ECSA 2025 supports an Open Science policy. We encourage all contributing authors to disclose (anonymized and curated) data/artifacts to increase reproducibility. Note that sharing research artifacts is not mandatory for submission or acceptance. Upon submission to the research track, authors are required: • To make their artifacts available to the program committee (via a link to an anonymous repository) and provide instructions on how to access this data in the paper; or • To include in the paper an explanation as to why this is not possible or desirable; and • To indicate why they do not intend to make their data or study materials publicly available upon acceptance, if that is the case While sharing research artifacts is not mandatory for submission or acceptance, authors are required to include a Data Availability statement after the Conclusions section in a section named "Data Availability". This statement should explain whether or not data and/or artifacts are available or how they could be accessed (or not). Upon acceptance, papers with Open Science artifacts (e.g., data, tools, etc.) will be invited to upload their artifacts into the ECSA Zenodo community (https://zenodo.org/communities/ecsa/) to make them accessible and visible to the ECSA community. Sharing artifacts via the ECSA Zenodo community is required for authors to be eligible for the best Open Artifact award. All contributions must be formatted according to the Springer LNCS style (https://www.springer.com/gp/computer-science/lncs/conference-proceedings-gu…). Page limits include figures and references. Contributions need to be submitted in PDF format via EasyChair to the ECSA 2025 Research Track: https://easychair.org/conferences/?conf=ecsa2025. Please select the “Research Track” in EasyChair for your submission and click "Continue". The proceedings will be published by Springer as part of the LNCS series. We also plan to organize a Journal Special Issue on the theme of ECSA 2025 and to invite authors of selected papers to submit an extended version of their research. INDUSTRY PAPERS The Industry Track at ECSA 2025 brings together practicing software architects and software architecture researchers from regional, European, and worldwide communities. We are seeking contributions from industry that share challenges, practical solutions, successful practices, failures, and lessons learned while analyzing, designing, implementing, evaluating, and evolving software architectures. Topics of interest include, but are not limited to the following themes: • Experience with architectures for emerging technologies, like LLM, and Agent-based system • Domain-specific challenges for software architects and architectures • Architecture specification and documentation • Architectural patterns, tactics, and tools • Practices and methods supporting architecture design, evaluation and evolution • Integration of architectural practices and methods with other software engineering approaches/practices/methods (e.g. Agile) • Social and organizational aspects, like human-machine, human-AI interactions, human-in-the-loop The ECSA 2025 Industry track aims to contribute to bridging the gap between academia and industrial practice by establishing an open communication and discussion environment. It will offer researchers and practitioners the opportunity to interact with fellow professionals and develop new ideas and skills for addressing industrial problems and collaborations. There are three ways to contribute: Full Papers (up to 16 pages in Springer LNCS style) describing best practices and experience from applying novel approaches to large-scale industrial projects in the context of software architecture. Submissions will be selected based on originality, quality, soundness, practical relevance, and potential for discussion. Short Papers and Presentations (6-10 pages in Springer LNCS style) outlining presentations on practices and experience related to software architecture from the industry. Submissions will be selected based on originality, practical relevance, and potential for discussion. Software Architecture Showcases (6 pages in Springer LNCS style) demonstrating a specific real-world architecture (including its flaws) together with a discussion of the context, challenges, and/or process that led to its present form. It can be formulated as an abstract outlining the architecture to be presented, preferably together with links to externally available work products. Submissions will be selected based on the offered insights into real architectural work, work products, and learnings related to architecture. All contributions need to be written in English, must be original, not published, accepted, or submitted for publication elsewhere. If accepted, each contribution needs to be presented by one of the authors who is registered at the conference. All contributions must be formatted according to the Springer LNCS style (https://www.springer.com/gp/computer-science/lncs/conference-proceedings-gu…). Page limits include figures and references.
