Despite the importance of systematically characterizing and understanding this relationship, little has been done in this realm mainly due to the lack of proper mechanisms for both sharing information between IT project phases and learning from past experiences. To tackle this issue, we present a Bayesian model to perform support cost predictions based on data from software development and test phases. In addition, we present a qualitative and quantitative analysis of the model, in order to demonstrate its effectiveness and efficiency, and also discuss its potentialities and limitations.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"67 1-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123469111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agile methods have also had an impact on software engineering education with universities adapting their courses to accommodate this new point of view of software development. Software engineering research has tried to evaluate the impact of agile methods in industrial projects and discover in which situations it is beneficial to apply such methods. However, there are still few studies focusing on the progress of the Agile Movement in Brazil.In this paper, we present an overview of the evolution of the Agile Movement in Brazil, outlining the history of its first advocates in academia and industry. We also describe existing educational initiatives and the impact of agile development on the national research and present a report on the agile state-of- the-practice in the Brazilian IT industry.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127949357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, there is an urgent need for software engineeringtechniques for MAS-based systems that guide the processes of design, development and maintenance. Without adequateprocesses and techniques such systems will not be sufficientlydependable, robust, trustworthy nor easily extended. This paper discusses the sub-areas of MAS Software Engineering research and development that have been focus of our research group in the software engineering laboratory (LES) at PUC-Rio. We give examples of relevant results and present a subset of the extensive literature the group has produced during the last decade. We also report how we managed to face the challenges that emerged from our research by organizing and developing a research community at the intersection of software engineering, programming and MASs with a concern for scalability of solutions.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134115367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Models used in this area describe computer systems, i.e. they not only describe static aspects but also dynamic aspects of systems behavior. Many different types of models have been used to build and analyze software systems, describing the system from different points of view and also at different levels of abstraction. As in other engineering disciplines, models must be accurate and non ambiguous. This means they must be expressed in languages with formally defined syntax and semantics. Based on these formal models, it is possible to define methods to build, analyze, transform, compare, and maintain software systems. This article discusses the presence of formal methods over the 25 years of SBES, including the creation of the Brazilian Symposium on Formal Methods and discusses potential developments for the area.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127517197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SBSE contributes to reduce efforts and costs associated to software development since the solutions found by search techniques satisfy constraints that are usually in conflict and, in general, are very difficult to be obtained for software engineers. The field is emerging in Brazil, the number of published works and research groups have significantly increased in the last three years. The goal of this paper is to divulge SBSE, serving as a reference to this novel field and contributing to its consolidation in Brazil.

This paper presents the results of an experimentation of the Model Driven RichUbi in the adaptive rich interfaces development against a not model-driven process based on the classic software life cycle. The experiment was conducted with groups of senior students from Computer Science and Computer Engineering undergraduate courses, in order to evaluate the teams' efficiency based on the data of development time and implemented lines of code collected during the processes execution. The results reported in this paper show that the groups which applied the Model Driven RichUbi process were, in general, faster and more productive for developing adaptive rich interfaces than the other groups.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121196792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such analysis is useful to understand the dynamics of refactoring throughout development, especially in multi-developer environments, such as open source projects. In this work, we propose a fully automatic technique to analyze refactoring frequency, granularity and scope in software repositories. It is based on SAFEREFACTOR, a tool that analyzes transformations by generating tests to detect behavioral changes -- it has found a number of bugs in refactoring implementations within some IDEs, such as Eclipse and Netbeans. We use our technique to analyze five open source Java projects (JHotDraw, ArgoUML, SweetHome 3D, HSQLDB and jEdit). From more than 40,723 software versions, 39 years of software development, 80 developers and 1.5 TLOC, we have found that: 27% of changes are refactorings. Regarding the refactorings, 63,83% are Low level, and 71% have local scope. Our results indicate that refactorings are frequently applied before likely functionality changes, in order to better prepare design for accommodating additions.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115617046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More recently, software evolution researchers have investigated logical dependencies between artifacts to assess failure-proneness, detect design issues, infer code decay, and predict likely changes. However, the interplay between these two kinds of dependencies is still obscure. By mining 150 thousand commits from the Apache Software Foundation repository and employing object-oriented metrics reference values, we concluded that 91% of all established logical dependencies involve non-structurally related artifacts. Furthermore, we found some evidence that structural dependencies do not lead to logical dependencies in most situations. These results suggest that dependency management methods and tools should rely on both kinds of dependencies, since they represent different dimensions of software evolvability.","PeriodicalId":142932,"journal":{"name":"2011 25th Brazilian Symposium on Software Engineering","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133685112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
