Sustainability in Software Engineering: A Systematic Literature Review for Building up a Knowledge Base <s> E. Related Work <s> Sustainability has become one of the "grand challenges" of our civilization. Because of their pervasiveness, the way we design, and consequently use, software-intensive systems has a significant impact on sustainability. This gives software requirements engineering an important role to play in society. However, there is currently no specific support for handling sustainability requirements, while such support exists and has proved useful for other quality requirements like security or usability. This paper reports on a software project in which sustainability requirements were treated as first class quality requirements, and as such systematically elicited, analysed and documented. The authors intended to assess how current techniques support these activities. Beyond raising awareness on the importance of sustainability concerns in requirements engineering, this experience report suggests that, while a lot of work remains to be done, small and easy steps may already lead us to more sustainable systems. It also contributes to the agenda of requirements engineering researchers concerned with sustainability. <s> BIB001 </s> Sustainability in Software Engineering: A Systematic Literature Review for Building up a Knowledge Base <s> E. Related Work <s> BACKGROUND: Systematic Literature Reviews (SLRs) have gained significant popularity among software engineering (SE) researchers since 2004. Several researchers have also been working on improving the scientific and technological support for SLRs in SE. We argue that there is also an essential need for evidence-based body of knowledge about different aspects of the adoption of SLRs in SE. OBJECTIVE: The main objective of this research is to empirically investigate the adoption and use of SLRs in SE research from various perspectives. METHOD: We used multi-method approach as it is based on a combination of complementary research methods which are expected to compensate each others' limitations. RESULTS: A large majority of the participants are convinced of the value of using a rigorous and systematic methodology for literature reviews. However, there are concerns about the required time and resources for SLRs. One of the most important motivators for performing SLRs is new findings and inception of innovative ideas for further research. The reported SLRs are more influential compared to the traditional literature reviews in terms of number of citations. One of the main challenges of conducting SLRs is drawing a balance between rigor and required effort. CONCLUSIONS: SLR has become a popular research methodology for conducting literature review and evidence aggregation in SE. There is an overall positive perception about this methodology. The findings provide interesting insights into different aspects of SLRs. We expect that the findings can provide valuable information to readers on what can be expected from conducting SLRs and the potential impact of such reviews. <s> BIB002
There are systematic literature reviews on different topics in software engineering, but so far none has been conducted that investigates the relation between sustainability and software engineering. Mahaux et al. BIB001 performed a preliminary search on the DBLP Computer Science Bibliography database BIB002 . For articles with the prefixes "sustainab-" OR "ecolog-" OR "environmental-" in the title, the data base returned over 3000 results (in January 2010), but filtering on important software-related venues lead to as few as 11 results. They propose that a systematic literature review should be conducted. In contrast to BIB001 , we are interested in publications from all scientifically sound venues and journals as we see great potential for learning from other domains. Therefore, we did not restrict this systematic literature review to softwarerelated venues, which is the main reason why we received more results.
