Systematic literature reviews in software engineering a systematic literature review

ISSN Systematic reviews of the literature have become an important methodology within software engineering research. In applying this methodology the critical aspects are related to achieving an appropriate design and execution, as well as an effective search strategy. Hence the need to find a design, implementation and evaluation approaches to optimally extract information from the scientific literature.

The main objective of this research is to analyze the methodological structure of the systematic reviews of literature carried out in Software Engineering evidencing the evolution of the different stages considered. For this, a systematic mapping study was carried out using the publications in the last 8 years in the Scopus and Wos databases.

We assert that there is a need of evidence based body of knowledge about the application of systematic reviews in software engineering. To address this need, we have started an empirical research program that aims to contribute to the growing body of knowledge about systematic reviews in software engineering. This paper reports the design, logistics, and results of the first phase empirical study carried out in this program. The results provide interesting insights into different aspects of systematic reviews based on the analysis of the data gathered from 17 interviewees with varying levels of knowledge of and experiences in systematic reviews.

The findings from this study are expected to contribute to the existing knowledge about using systematic reviews and help further improve the state-of-the-practice of this research methodology in software engineering. Article :. DOI: Systematic review quality Results: Of 20 relevant studies, eight addressed research trends rather than technique evaluation. Seven Cost estimation SLRs addressed cost estimation. The quality of SLRs was fair with only three scoring less than 2 out of 4. Conclusions: Currently, the topic areas covered by SLRs are limited.

European researchers, particularly those at the Simula Laboratory appear to be the leading exponents of systematic literature reviews. The series of cost estimation SLRs demonstrate the potential value of EBSE for synthesising evidence and making it available to practitioners. All rights reserved. Contents 1.
