“…Conversely, Wendorff reports that the "uncontrolled use of patterns" caused, in their case, "severe maintenance problems" [11, p. 77]. In general, we find support both for (e.g., [8], [9], [10]) and against (e.g., [6], [7], [11]) design patterns, for each of several related attributes-modifiability, maintainability, understandability, quality, and so forth. In response to these and other contradictory findings, the authors of a recent (2012) systematic literature review conclude, "We could not identify [aside from two marginal caveats] firm support for any of the claims made for patterns in general" [12, p. 1213], [13].…”

“…Similarly, in the Bayesian models, we find (for all tasks) that the effect of variant is more significant at individual sites than when generalized across sites (uT1,C1:46-54,791-826). 6 For example, on CO task 2, the marginal 6. We use references of this form to map specific assertions back to the Bayesian probabilities on which they are based.…”

“…After filtering, a 1-unit (or approx. 17%) increase in patKnow yields an average correctness increase of 11 percentage points for CO (80% CI: [4][5][6][7][8][9][10][11][12][13][14][15][16][17], as well as a 30% time decrease for GR (80% CI: [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. patKnow is also significant in the CO time model, but in that case its marginalized effect is not meaningful because the patKnow ⇥ variant interaction also becomes significant (pvalue = 0.029).…”

Context. Several empirical studies have explored the benefits of software design patterns, but their collective results are highly inconsistent. Resolving the inconsistencies requires investigating moderators-i.e., variables that cause an effect to differ across contexts. Objectives. Replicate a design patterns experiment at multiple sites and identify sufficient moderators to generalize the results across prior studies. Methods. We perform a close replication of an experiment investigating the impact (in terms of time and quality) of design patterns (Decorator and Abstract Factory) on software maintenance. The experiment was replicated once previously, with divergent results. We execute our replication at four universities-spanning two continents and three countries-using a new method for performing distributed replications based on closely coordinated, small-scale instances ("joint replication"). We perform two analyses: 1) a post-hoc analysis of moderators, based on frequentist and Bayesian statistics; 2) an a priori analysis of the original hypotheses, based on frequentist statistics. Results. The main effect differs across the previous instances of the experiment and across the sites in our distributed replication. Our analysis of moderators (including developer experience and pattern knowledge) resolves the differences sufficiently to allow for cross-context (and cross-study) conclusions. The final conclusions represent 126 participants from five universities and twelve software companies, spanning two continents and at least four countries. Conclusions. The Decorator pattern is found to be preferable to a simpler solution during maintenance, as long as the developer has at least some prior knowledge of the pattern. For Abstract Factory, the simpler solution is found to be mostly equivalent to the pattern solution. Abstract Factory is shown to require a higher level of knowledge and/or experience than Decorator for the pattern to be beneficial.

“…Similar studies to those discussed in our work have been conducted for design patterns [3]: Heuzeroth et al presented an approach to support the understanding of software systems by detecting design patterns automatically using static and dynamic analyses [5]. Aversano et al report an empirical study showing that for three open source projects, the number of defects in design-pattern classes is in several cases correlated with the scattering degree of their induced crosscutting concerns, and also varies among different kinds of patterns [6].…”

One of the goals of Software Engineering is to reduce, or at least to try to control, the defectiveness of software systems during the development phase. The aim of our study is to analyze the relationship between micro patterns (introduced by Gil and Maman) and faults in a software system. Micro patterns are similar to design patterns, but their characteristic is that they can be identified automatically, and are at a lower level of abstraction with respect to design patterns. Our study aims to show, through empirical studies of open source software systems, which categories of micro patterns are more correlated to faults. Gil and Maman demonstrated, and subsequent studies confirmed, that 75% of the classes of a software system are covered by micro patterns. In our study we also analyze the relationship between faults and the remaining 25% of classes that do not match with any micro pattern. We found that these classes are more likely to be fault-prone than the others. We also studied the correlation among all the micro patterns of the catalog, in order to verify the existence of relationships between them.

The implementation of crosscutting concerns in object-oriented (OO) systems entails scattering and tangling of code across several components increasing code duplication and making the system harder to comprehend, maintain, evolve and reuse. Therefore, identification of crosscutting concerns drives the reengineering or refactoring tasks in order to improve modularization of an existing system and increasing its overall internal quality. This paper proposes an approach to identify and analyse the components implementing the static and dynamic crosscutting in OO systems. The approach defines a meta-model representing the structure of an OO system in terms of its components. A static analysis of an OO software system is performed to create an instance of this meta-model. Such meta-model is finally analysed to find static and dynamic crosscutting among concerns. The effectiveness and efficiency of the proposed approach have been validated in an empirical assessment where it was applied to some OO java systems. The obtained results show a good level of effectiveness for the crosscutting analysis.
