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

The International Conference on Software and Systems Reuse, Product Lines, and

Configuration (VARIABILITY 2026) invites high-quality contributions from researchers and

practitioners in software engineering, systems engineering, and related disciplines

focussing on a broad spectrum of methods, concepts, and tools for variability.

VARIABILITY aims to be the premier forum for the exchange of ideas, experiences, and

results in all aspects of software and systems variability management, reuse, software

configuration, and customization.

 

As software and systems become increasingly configurable, reusable, and adaptable,

managing their variability across all lifecycle phases is more critical—and more challenging

—than ever. VARIABILITY 2026 seeks to bring together the diverse communities that

address these challenges from theoretical, technical, and practical perspectives.

 

VARIABILITY results from a merge of three prominent conferences focussing on software

and systems variability, configuration and reuse: SPLC (the International Systems and

Software Product Line Conference, 29 successful editions), VaMoS (the International

Working Conference on Variability Modelling of Software-Intensive Systems, 19 successful

editions), and ICSR (the International Conference on Systems and Software Reuse, 22

successful editions).

 

VARIABILITY is by design open as a conference. It welcomes new fields of variability-

intensive research, such as artificial intelligence, hybrid software-hardware systems, etc.

For this first edition of VARIABILITY, we strive to continue the success of the predecessor

conferences ICSR, SPLC, and VaMoS by welcoming high-quality submissions for the

research track in numerous closely related areas, such as systems and software product

lines, systems and software reuse, configurable systems and software, product

configuration, and systems and software variability.

 

 

Publication of Proceedings

 

All accepted contributions will be published by Springer in the LNCS series. For more

information, including the submission link, please refer to the conference website.

Tracks and Types of Submission

 

Research Track

• Full Papers (up to 18 pages excluding references): Research papers must present

original, unpublished work with validated results through empirical evaluation, formal

analysis, or implementation-based experiments. Submissions must clearly articulate the

problem, its relevance, the proposed contribution, and validation results.

 

• Short Papers (6 - 8 pages excluding references): Short papers present early-stage

research, novel ideas, or conceptual proposals that are not yet fully developed or

validated but offer promising directions. These papers should articulate the vision,

motivation, and potential impact.

Journal First

To qualify for a Journal-First presentation at VARIABILITY 2026, a paper must meet these

criteria:

• It was published on the publisher’s website between May 2024 and March 2026.

• It fits within the scope of VARIABILITY 2026, as described in the research track call

(https://conf.researchr.org/track/variability-2026/variability-2026-papers#Call-for-Papers),

and can bring new insights or directions to the community.

• It presents new research results or significant extensions of prior work that have not

been presented at SPLC, VaMoS, or ICSR before.

• It has not been presented at, and is not under review for, Journal-First Tracks of other

related conferences.

 

For detailed information please refer to the conference website:

https://conf.researchr.org/track/variability-2026/variability-2026-journal-first

 

Project Showcases

We welcome submissions on research projects that address reuse, product lines, and

variable/configurable software systems. 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

 

For detailed information please refer to the conference website:

https://conf.researchr.org/track/variability-2026/variability-2026-project-showcase

 

Demos and Tools

Submissions must describe either (1) a new tool or prototype; (2) a novel extension to an

existing tool; (3) a practical demonstration of an approach; (4) a new or curated dataset

relevant to variability and reuse; (5) a significant update to a previously published tool or

dataset (include a clear description of new contributions).

 

Each submission must include:

• A paper of up to 4 pages, including references and figures.

• An optional appendix of up to 2 pages (not included in the proceedings), describing the

planned live demonstration or dataset usage scenario.

• A link to a short video (max. 5 minutes) illustrating the tool, demonstration, or dataset

in action.

Doctoral Symposium

The Doctoral Symposium of VARIABILITY 2026 aims to provide a supportive environment

that enables doctoral students to get constructive feedback on their research. Students

will discuss their work with experienced community members and other students. The

event is open to any PhD student whose research topic concerns software variability,

software and systems reuse, product lines, and configuration. This includes PhD students

at early stages of their research (after setting up a research program, but before having

results).  Accordingly, we will have two submission categories:

• Late – late-stage PhD students, having at least 6 months of work after the conference

and before their expected completion; and

• Early – early-stage PhD students, with at least 6 months of work already performed

prior to the submission date.

Industry Track

The Industry Track of VARIABILITY 2026 offers a platform for practitioners, researchers,

and technology leaders to share practical experiences in industrial settings with reuse,

variability management, configuration, and product line engineering across software and

systems. Building on the industrial tracks of SPLC, VaMoS, and ICSR, this track bridges

research and practice by showcasing how variability, reuse, and product line strategies are

being applied and developed in today’s fast-changing industrial environments.

 

For detailed information please refer to the conference website:

Workshop Proposals

We invite you to submit proposals for half-day or full-day workshops in any area related

to the field of Software and Systems Reuse, Product Lines, and Configuration, all of which

fall under the broader area of Variability. In particular, workshops on challenging,

emerging areas related to the conference topics are especially sought. We particularly

encourage workshop proposals for highly interactive and collaborative workshops, rather

than mini-conferences, e.g., apart from the traditional short and long papers, consider

allowing position papers with only one page (not included in the proceedings) and focus

on a lively discussion after the presentation, to foster new ideas and gather feedback

(rather than just defending the presented work). The expected date of the workshops

will be the September 29th, 2026, before the main track of the conference.
