RE4SuSy: 3rd International Workshop on Requirements Engineering for Sustainable Systems Birgit Penzenstadler University of California, Irvine Irvine, USA bpenzens@uci.edu Martin Mahaux University of Namur Namur, Belgium martin.mahaux@fundp.ac.be Camille Salinesi Universit´ e Paris 1 - Sorbonne Paris, France camille@univ-paris1.fr Abstract—Research has started investigating the support of sustainability within systems and software engineering.Yet there are few workshops that explore the topic, and there is only one so far in requirements engineering: RE4SuSy. The International Workshops on Requirements Engineering for Sustainable Systems (RE4SuSy) have been held at REFSQ in 2012 and at RE in 2013. We want to continue this series back in Europe at RE’14. We plan an interactive workshop that engages with authors well before the deadlines and that produces new results already during the workshop and will promote them throughout the conference. This is also the take-off point for new collaborations between participants. I. MOTIVATION AND OBJECTIVES A. Motivation Researchers have recently started to explore the concept of ”sustainability requirements”, and how to support the elicita- tion and documentation of such requirements. They are show- ing that requirements engineers have indeed a very important role to play in order to ensure that future socio-technical systems are sustainable. For example, requirements have an important impact on the potential premature obsolescence of hardware, on the electricity consumption of software or on the number of servers needed to offer a service. Further, as ubiquitous socio-technical systems alter the way we live, the requirements of those systems have to be carefully written such that those new ways of living are more sustainable. In the industry, companies not only want to be “ecologically trendy”, but also become aware that sustainability require- ments will have strategic impacts on business organization and value creation, as with zero paper projects that revolutionize enterprise architectures, or intelligent powergrids that lead to delivering innovative services. This workshop will provide an interactive stage for re- searchers to share and exchange about their latest works, to collaboratively define a research agenda in RE for sustainable systems, and also to jumpstart collaboration through the live creation of teams that commit to work together on concrete points of this agenda. B. Objective The objective of the workshop is to establish a community of researchers interested in collaborating on the topic of sustainability in requirements engineering. The basis for this is provided by: • the earlier workshops and their derived research agendas • various international research collaborations (i.a., with Germany, Spain, Belgium, Brazil, USA, Netherlands) that have started in the past two years This objective shall be reached by the following actions: • provide a platform for researchers where they can present their current work and trigger discussion • revisit and add to the defined research agendas • identify and link contributions to that agenda where there has already been work done or work is in progress • trigger discussions in small groups on favored topics of the research agenda • kickstart new collaborations in between the workshop participants • spread the word about the workshop and its results at the main conference How the actions are planned to be realized within the work- shop is described in the following section. II. HISTORY OF THE WORKSHOP Related workshop on sustainability, green software, and software engineering are GREENS 1 (at ICSE’12 and ’13), WSRCC 2 (at OOPSLA’09, ICSE’10, CAISE’11), and GIBSE 3 (AOSD’13), but none of them explicitly considers require- ments engineering. The 1st Intl. Workshop on RE4SuSy 4 was held at the International Working Conference on REFSQ 5 in March 2012. We had 8 contributions that were presented at the workshop and 14 attendees. Much of the workshop was dedicated to the collaborative building of a first research agenda for the discipline. The 2nd Intl. Workshop on RE4SuSy 6 was held at the International Conference on Requirements Engineering in July 2013, with 7 contributions and 17 attendees. The af- ternoon of the workshop was dedicated to discussion in 1 http://greens.cs.vu.nl/ 2 http://www.cs.toronto.edu/wsrcc/Previous.html 3 http://trese.ewi.utwente.nl/workshops/GIBSE/ 4 https://sustainability.wiki.tum.de/RE4SuSy 5 http://refsq.org 6 http://www4.in.tum.de/ ∼ penzenst/re4susy/2013/
