-The RE4SuSy workshop series has established a strong and growing research community around the different aspects of sustainability and how to support them in requirements engineering. Since requirements define how and what a software will do, we maintain that requirements engineering is the key point in software engineering through which sustainability can be fostered. Thus, the RE4SuSy workshop series is concerned with research on techniques, tools, and processes for sustainability through requirements engineering. Yet, so far, the the series has not made any effort in converging the RE for sustainability community towards a common set of fundamentals. This edition of the RE4SuSy workshop will initiate the first convergence discussion to elicit what characteristics a requirement should process, or what constraints should it meet in order to be called a ”sustainability requirement”. RE4SuSy is an interactive workshop: the contributors and prospective participants will engage well before the workshop date through on-line collaborative writing, discussion, and peer feedback. The workshop aims to foster community growth by supporting new collaborations, holding preliminary case studies, discussions, and birds-of-a-feather group work.
Software is a main driver for change in business and society, in changing life styles as well as business practices. Since requirements are the starting point for defining software, requirements engineering is the key point in software engineering through which sustainability can be fostered.
This workshop aims to provide an interactive stage for researchers and practitioners to share and exchange their latest work, to collaboratively work on expanding the body of knowledge in RE for sustainable systems, and to jumpstart new collaborations through the live creation of teams that commit to work together on concrete topics and in-workshop case studies and experiments.
In addition, this year we will start on the work of consensus building around the key notions of RE for sustainability. For the last few years, researchers have been exploring the notion of “sustainability requirements”, and how to support the elicitation, documentation, and conflict resolution of such requirements. Yet, there still is no common understanding as to what makes a requirement into a “sustainability requirement”. Some, for instance, insist that only requirements that support environmental needs are ”sustainability requirements”, others consider sustainability to be inclusive of social, individual, economic, and technical domains as well. So how then does a requirement becomes a ”sustainability requirement”? One of the key tasks of this edition of the worksop is to elicit a common ground amongst the workshop participants in answering this question.
The objective of the workshop is to establish a community of researchers and practitioners interested in collaborating on the topic of sustainability in requirements engineering. This community will expand and build on the work already initiated in the past editions of this workshop, such as the research agendas and the the Karlskrona Manifesto on Sustainability Design. The workshop also aims to establish a common ground on the key topics of RE for Sustainability. These objective shall be supported in the workshop through the following actions: Call for submission of key topics and definitions for Requirements Engineering in Sustainability (with the ”sustainability requirement characteristics” provided as an example topic by the organisers of the workshop); Working sessions to discuss the submitted topics and apply the emerging ideas to a demonstrator case study; Provision of a platform for researchers and practitioners to present their current work and trigger discussion; Continued collaboration on the previously initiated topics (e.g., Karlskrona Manifesto on Sustainability Design); Support for group work and discussion on newly favored topics; Kickstart new collaborations between the workshop participants Publication of a white paper on the common fundamentals of RE for Sustainability; Dissemination of the workshop ideas and results at the main conference.
This is the only workshop that focuses on the topics of sustainability in and through RE. It has been held in four previous instances: The 1st Intl. Workshop on RE4SuSy1 was held at the International Working Conference REFSQ 1https://sustainability.wiki.tum.de/RE4SuSy in March 2012. It had 8 contributions that were presented at the workshop and 14 attendees. The 2nd Intl. Workshop on RE4SuSy was held at the International Conference on Requirements Engineering in July 2013, with 7 contributions and 17 attendees. The 3rd Intl. Workshop on RE4SuSy was held at the International Conference on Requirements Engineering in August 2014, with 8 contributions and 14 attendees. The afternoon was dedicated to working on the Karlskrona Manifesto for Sustainability Design, which continued to be developed throughout the conference and was presented on the last day to the plenary. The working group established for this continues to collaborate actively on this topic. The 4th Intl. Workshop on RE4SuSy2 was held at RE’15 in Ottawa, with 7 contributions and 17 attendees. The 5th edition of the workshop, held last year, did not attract many participants, mainly due to location of the workshop. However, our initial poll of the RE4SuSy community indicates much more interest in attending the workshop at Lisboa than last year.
Related workshops on sustainability, green software, and software engineering are GREENS3 (at ICSE’12, ’13, ’14, and ’15), WSRCC4 (at OOPSLA’09, ICSE’10, CAISE’11), and GIBSE5 (AOSD’13 and Modularity’15), but none of them explicitly considers requirements engineering.
As of 2015, RE4SuSy has been part of the newly formed GREENS alliance that brings together all these workshops around sustainability in software engineering (each focused on different areas of Software Engineering) .
III. WORKSHOP CONTRIBUTIONS AND EVALUATION
The workshop solicits a number of contribution types: fundamental concept submission up to 2 pages, defining the concept and explaining why it is fundamental for RE for sustainability. These will be used to map out the set of key notions and start discussion on converging towards common grounds around these fundamental concepts; user studies/experiments for the duration of an hour with a maximum description of 6 pages. One or two studies will be selected to run as working sessions at the workshop. We encourage submissions related to the fundamental notions in RE 4 Sustainability; case study reports on RE 4 Sustainability, 6 - to 10 pages long; full papers of 10 pages, short papers of 6 pages, posters with a 2-page abstract, videos of up to 5 minutes (also with 2 pages abstract), open collaboration papers (long or short) (new submission format). Here, author(s) can solicit for open collaboration on a paper. The solicitation starts at least two months before submission deadline, via a form on the 2http://web.csulb.edu/ bpenzens/re4susy/ 3http://greens.cs.vu.nl/ 4http://www.cs.toronto.edu/wsrcc/Previous.html 5http://trese.ewi.utwente.nl/workshops/GIBSE/ RE4SuSy webpage. The paper will be hosted and written via a collaborative edition platform (framapad, overleaf, pirate pad, etc.), see also pre-workshop activities.
We encourage the submission of new and interactive formats, which can be presented as such at the workshop, and published in the workshop proceedings with textual descriptions.
The submission, review process, and communication will be performed via the Easychair system. The contribution ratings will include the option of a conditional accept as we consider it more sustainable to request specific improvements instead of rejections of potentially good contributions. In case one or more of the organizers decide to submit a contribution, the reviews will be handled in an adequate way to preserve blind review rules.
The program committee we plan to invite is a mix of representatives from different domains of requirements engineering and sustainability.

There are three phases of pre-workshop activities: 1) Open collaboration: We solicit open collaboration papers that start at least two months before the deadline on an open collaboration platform. Authors are encouraged to advertise this on the workshop website. 2) Shepherding: Four weeks before the submission deadline, authors are invited to upload the preliminary abstracts, outlines, or papers for a constructive feedback phase. Other authors and interested PC members can comment on them so the authors can improve their papers before the actual submission. 3) Reading: In a pre-workshop reading phase from the CR deadline until the workshop, we provide the cameraready version papers in a protected download area for authors and PC members. That way participants are already engaging with the contents before the actual workshop and discussion is facilitated.
B. Workshop format
1) Warm-up and intro: Before the workshop each attendee will be asked to submit a single slide that summarises their research interest and work related to the workshop. A copy of this slide-set will be share with all attendees. The workshop will be kicked off with an interactive warm-up exercise where the participants introduce themselves and their slide. This is aimed at facilitating introductions, clarifying the positions, and identifying discussion topics and collaboration opportunities.
2) Contribution presentations: A small set (3 to 4) accepted papers will be presented to provide further input into the subsequent discussion sessions. All accepted papers will be available in advance of the workshop as password-secured download. In parallel, we will be taking notes in a shared online document as a living protocol of the workshop. Authors of accepted papers will be encouraged to prepare a poster. These will be displayed in the workshop room on the walls to enable further discussions and collaboration during breaks, lunchtime, or after the workshop.
3) ”Sustainability Requirement”: Moving towards a common ground in the notion of the ”Sustainability Requirement” will be one of the discussion topic options for group discussion.
4) Concepts, Collaboration, and Studies: Topics for work in breakout sessions with discussion facilitation (e.g. creativity techniques like the Osborne checklist, role-play, etc.) will be collected from accepted papers during the review stage as well as during the workshop itself. The afternoon will be dedicated to group work, with each group focusing on one or two selected topic. Related fundamental concept submission will automatically form a discussion group topic. The breakout sessions will be also used to facilitate new collaborations amongst attendees. Specific attention will be given to study design to evaluate concepts early on.
5) Experiments: Furthermore, if we accept experiment proposals, one to two hours will be allocated to working on experiments.
6) Final Wrap-up: In a final come together, we will gather and share the major discussion points of the day and group work results all workshop.
a) Results: The workshop results will include: A workshop report, formatted as an online protocol of the workshop; A white paper on the common fundamentals of RE for Sustainability; Updated research agenda and challenges; New research collaborations initiated through discussion groups and collaborative writing; Experiments / user studies and study designs carried out at the workshop. The results of these will be shared with the participants and the workshops as a whole.
A wrap-up of results to be presented at the main conference A further strengthened community of actively collaborating researchers
The post-workshop activities will be focused around completing writing of the white paper; intensifying collaborations that originated during the workshop; having informal working sessions both in person and on-line. The workshop results will also be shared with the main conference. Results of the workshop will be shared via the online protocol for all interested parties.
Room with 20 chairs and tables for them as well as a projector. The preferred setting is a U-shape. The room shall provide enough space so we can move around along the walls during interactive sessions.
Free walls for the posters of the workshop.
More free walls where we are allowed to (temporarily) stick many post-its and pieces of papers to collect and organise ideas.
Harmonized feedback forms would be welcome.
We plan to publish workshop proceedings with the free and public CEUR WS proceedings.
The organising team (along with the interested workshop participants) will write a white paper, and a workshop report and make it available in an adequate publication. The workshop report will be based on the protocol elaborated collectively online during the day and participants are welcome to co-author.
The workshop is aimed to researchers and practitioners working on/with requirements engineering or broader software and systems engineering topics and with interest in sustainability. As this is a particularly interdisciplinary topic, we also hope to encourage interdisciplinary contributions.
