The systematic literature reviews (SLRs) are a formally planned approach in finding, evaluating and summarising all available evidence on a specific research question. The objective of this paper is to compare formal SLRs and informal literature reviews in software engineering. For this purpose, a SLR has been conducted to compare the results with a previously conducted informal literature review of software process improvement success factors. Previous research using an informal literature review approach found 47 articles via the snow balling technique. For formal literature reviews, the SLR was conducted by applying customised search strings covering the time to 30 June 2004 (this is the deadline of the informal literature review). In total, 38 relevant articles were identified via the formal literature review. The results show that the data extraction process in the formal literature review enabled more success factors to be extracted (i.e. 34) than the informal literature review (i.e. 18). In the formal literature review, the publication inclusion and exclusion criteria and selecting primary studies helped in identifying the right list of publications. A real challenge in the formal literature review was to define a search string. In general it was observed that the SLR methodology is better than the informal literature review with respect to the planning for literature review, the design of search string, sources to be searched, publication inclusion and exclusion criteria, publication quality assessment and the data extraction process. However, the informal literature review has identified more articles than the formal literature review. Snow balling technique should be used with the formal literature review in order to identify all the relevant articles.

“…In earlier studies, we found that neither refactoring to patterns nor other refactoring methods necessarily improve software quality [5,6]. These results motivated us to investigate the effect of each refactoring method on particular software quality attributes rather than on quality in general.…”

“…Accordingly, the originality of this research focuses on classifying refactoring methods, based on their measurable effect on several software quality attributes, internal and external This enables improvement in these quality attributes that, in turn, are indicators of good software quality. In this work, we use the same quality attributes used by Alshayeb in [5,6], in which he found that each refactoring method has a different impact on software quality.…”

Refactoring is the process of improving the design of existing code by changing its internal structure without affecting its external behavior. Refactoring tends to improve software quality by improving design, improving readability and reducing 'bugs'. There are many different refactoring methods, each having a particular purpose and effect. Consequently, the effect of refactoring methods on software quality attributes may vary. Moreover, it is often unclear to software designers how to use refactoring methods to improve specific quality attributes. In this paper, we propose a classification of refactoring methods based on their measurable effect on software quality attributes. This, in turn, helps software designers choose appropriate refactoring methods that will improve the quality of their designs, based on the design objectives. It also enables them to predict the quality drift caused by using particular refactoring methods.

“…The subject systems were selected from different domains (Java parser, class browser, neural networks and file manager) and different system sizes (number of classes range from 9-202). In this study, we focus on studying the effect of refactorings at the classlevel not at the overall system-level [34]. Therefore, the size of the system is not crucial.…”

Refactoring to patterns allows software designers to safely move their designs towards specific design patterns by applying multiple low-level refactorings. There are many different refactoring to pattern techniques, each with a particular purpose and a varying effect on software quality attributes. Thus far, software designers do not have a clear means to choose refactoring to pattern techniques to improve certain quality attributes. This paper takes the first step towards a classification of refactoring to pattern techniques based on their measurable effect on software quality attributes. This classification helps software designers in selecting the appropriate refactoring to pattern techniques that will improve the quality of their design based on their design objectives. It also enables them to predict the quality drift caused by using specific refactoring to pattern techniques
