Sustainability in Software Engineering: A Systematic Literature Review for Building up a Knowledge Base <s> I. MOTIVATION AND BACKGROUND <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> BIB001 </s> Sustainability in Software Engineering: A Systematic Literature Review for Building up a Knowledge Base <s> I. MOTIVATION AND BACKGROUND <s> Background: Supporting sustainability in software engineering is becoming an active area of research and we want to contribute the first SLR in this field. Researchers who are motivated to contribute to that topic need to accumulate a body of knowledge as starting point through time-consuming literature research. Aim: We aim to provide an overview of different aspects of sustainability in software engineer- ing research with regard to research activity, investigated topics, identified limitations, proposed approaches, used methods, available studies, and considered domains. Method: The applied method is a Systematic Literature Review (SLR) in five reliable and commonly-used databases according to the (quasi-standard) protocol by Kitchenham et al. [288]. We assessed the 100 first results of each database ordered by relevance with respect to the search query. Results: Of 500 classified publications, we regard 96 as relevant for our research questions. Most of the excluded publications were ruled out because of an unfitting usage of terms within the search query. We sketch a taxonomy of their topics and domains, and provide lists of used methods and proposed approaches. Conclusions: Currently, there is little research coverage on the different aspects of sustainability in software engineering. Future work includes extending the study by reviewing a higher number of publications, including dedicated journal and workshop searches, and snowballing. <s> BIB002
Sustainability is currently an omni-present term in calls for research proposals and conference sessions (ICSE, CAiSE, RE, etc.). However, in literature, there is no overview of the current state of the art in supporting sustainability in software engineering research and practice. Consequently, researchers who are motivated to contribute to that topic (like the first author  ) have to invest much time in finding a basic body of knowledge through literature research of many unrelated leads. This paper reports on our systematic literature review with the objective of retrieving a solid basis of knowledge  on the support of sustainability in software engineering.
