VARIABILITY 2026
Tue 29 September - Fri 2 October 2026

Call for 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.

VARIABILITY is a new conference that has been merged of three prominent conferences focussing on software and systems variability, onfiguration and reuse: SPLC (the International Systems and Software Product Line Conference, 29 successful editions, ranked as a top conference), 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).

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.

Submissions / Publishing

VARIABILITY workshop papers will be published in a volume of the conference proceedings published by Springer. Moreover, a one-page summary of each accepted workshop will be published in the proceedings as well.

Workshop proposals should be authored by at least two organizers, preferably from different institutions, and they should contain the following three sections and address each corresponding point:

1. Organizers

  • Name: organizers’ full names
  • Contact information: affiliations, job titles, postal addresses, e-mail addresses, URLs, and phone
  • Brief biography: 100-200 words, focusing on the organizers’ expertise in the field and experience as workshop organizers

2. Workshop Content

    • To avoid duplicated topics and cancellations, did you coordinate with or (plan to) merge workshops on the same/similar topics from previous years (if there are any)?
    • What will be done to stimulate collaborative interaction?
    • What are the planned pre- and post-workshop activities?
  • Participants:
    • What is the expected number of submissions and participants? Provide a plan for attracting sufficient submissions and promoting attendance
    • If applicable, please provide information from previous or related workshops. Have there been previous workshops on the same or a closely related topic? When, where and with how many participants?
    • Special room equipment (please note that VARIABILITY conference and the workshops are in-person events) like flip charts, microphone, etc.
    • Do you plan for a half-day or full-day workshop?
  • Program Committee: list of tentative program committee members, names and affiliations.

Relevant supporting material, such as proceedings from previous editions of the proposed workshop or other workshops organized by the proposal authors, should be included if available but are not required for submission.

Acceptance Criteria

Each workshop proposal will be evaluated according to the relevance of its topic, the expertise and experience of the workshop organizers, and the workshop’s potential for attracting participants and generating useful results. We underline the importance of active and creative workshops that foster a collaborative environment of interest to both practitioners and researchers, aiming, e.g., to evolve the field of Variability and to identify elements of joint future work. To obtain a balanced and cohesive workshop program, the Organizing Committee will collaborate closely with workshop organizers and reserves the right to circulate proposals to other submitters in view of possible workshop mergers. The organizers of accepted workshops will be required to create and maintain a website in a timely manner to serve as a workshop information center and to provide a repository for documenting pre- and post-workshop activities.

At least one author of each accepted proposal must register and attend VARIABILITY 2026 in order for the workshop to be accepted and the summary of the workshop published.

The submission and review platform for workshop papers will be the one for the main conference (i.e., all workshops will be as different tracks under the same Easy Chair installation).

MODEVAR - International Workshop on Languages for Modelling Variability

Workshop Homepage: https://modevar.github.io/

Description

Feature models were invented in 1990 and have been recognized as one of the main contributions to the Software Product Line community. Although several attempts have been made to establish and study a sort of standard variability modeling language (e.g., OVM, CVL, TVL, .) there is still no consensus on a simple feature modeling language. There can be many motivations to have one but among others, there is one that is very important: information sharing among researchers, tools, or developers. Following the spirit of the previous MODEVAR workshops, this meeting plans to be a full-day, interactive event where all participants shall share knowledge about how to build up a simple feature model language that the community can agree on.

Scope

We invite submissions considering topics related to variability modeling languages:

  • Concepts: domain modeling, language constructs, mapping to other artifacts.
  • Usages: writing, reading, generating, reverse engineering, (de-)composition, benchmarking.
  • Tools: (collaborative) editing, storage/repositories, exchange, translation to other representations, analyses, and testing.
  • Analyzing existing languages and approaches: Feature Modelling, Decision Modelling, OVM, UML-based, KConfig, Delta-Oriented Modelling, CVL, TVL, etc.

The topics are not limited to the list above. In particular, we invite submissions addressing the scope of the VaMoS conference.
