As metrics become increasingly complex, implementing them using imperative and interrogative programming is oftentimes cumbersome. Consequently, their understanding, testing and reuse are severely hampered. In this paper we identify a set of key mechanisms that are involved in the implementation of design metrics and, more general, of design-related structural analyses: navigation, selection, set arithmetic, filtering and property aggregation. We show that neither of the aforementioned approaches offers a simple support for all these mechanisms and, as a result, an undesirable overhead of complexity is added to the implementation of metrics. The paper introduces SAIL, a language designed to offer a proper support to a simplified writing of design metrics and similar design-related analyses, with special emphasis on object-oriented design. In order to validate the expressiveness of SAIL the paper provides a comprehensive comparison with the other two approaches","PeriodicalId":402415,"journal":{"name":"11th IEEE International Software Metrics Symposium (METRICS'05)","volume":"311 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116610172","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}

To systematically combine these processes in the context of an integrated quality assurance strategy, measurement must provide empirical evidence on how effective these processes are and which types of defects are detected by which quality assurance process. Typically, defect classification schemes, such as ODC or the Hewlett-Packard scheme, are used to measure defects for this purpose. However, we found it difficult to transfer existing schemes to an embedded software context, where specific document- and defect types have to be considered. This paper presents an approach to define, introduce, and validate a customized defect classification scheme that considers the specifics of an industrial environment. The core of the approach is to combine the software engineering know-how of measurement experts and the domain know-how of developers. In addition to the approach, we present the results and experiences of using the approach in an industrial setting. The results indicate that our approach results in a defect classification scheme that allows classifying defects with good reliability, that allows identifying process improvement actions, and that can serve as a baseline for evaluating the impact of process improvements","PeriodicalId":402415,"journal":{"name":"11th IEEE International Software Metrics Symposium (METRICS'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129486605","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}

We used two further industrial data sets in which we compare accuracy levels with and without this adjustment. Our results were broadly consistent with those from the Jorgensen study. Using the R2M resulted in a small increase in predictive accuracy. For one data set it was necessary to first partition it into more homogeneous subsets. Also when there was very weak correlation between predicted and actual productivity using the sample mean was the least bad strategy. We believe that independent validation of results is an important activity. Specifically our results add further support for the R2M approach in that there is a small, but positive, effect upon prediction accuracy. By combining results from both studies we observe a consistency across all 7 data sets","PeriodicalId":402415,"journal":{"name":"11th IEEE International Software Metrics Symposium (METRICS'05)","volume":"56 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123898343","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}

In many open-source projects, such as KDE, Gnome, Mozilla, Openoffice, change requests, and related data, are stored in a bug tracking system such as Bugzilla. These data, together with the data stored in a versioning system, such as CVS, are a valuable source of information on which useful analyses can be performed. In this paper we propose a method to derive the set of source files impacted by a proposed change request. The method exploits information retrieval algorithms to link the change request description and the set of historical source file revisions impacted by similar past change requests.

The flaws in the limitation of the UML diagrams are solved by specifying UML/OCL combined models, OCL being an essential add-on to the UML diagrams. Aware of the importance of building precise models, the main goal of this paper is to carefully describe a family of experiments we have undertaken to ascertain whether any relationship exists between object coupling (defined through metrics related to navigations and collection operations) and two maintainability sub-characteristics: understandability and modifiability of OCL expressions. If such a relationship exists, we will have found early indicators of the understandability and modifiability of OCL expressions. Even though the results obtained show empirical evidence that such a relationship exists, they must be considered as preliminaries. Further validation is needed to be performed to strengthen the conclusions and external validity","PeriodicalId":402415,"journal":{"name":"11th IEEE International Software Metrics Symposium (METRICS'05)","volume":" 14","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132188603","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}

This process aims at improving software engineering decisions. For the last three years, EBSE has been taught to university students at Hedmark University College, Rena, Norway. The motivation for the EBSE-course is that it is essential for the students, as future practitioners, to learn how to base important software engineering decisions on the systematic and critical evaluation of the best available evidence. The main purpose of this paper is to inspire and support other universities in their work on developing their own EBSE-courses. For this purpose we report on how our course has been organized and what lessons have been learned. There are currently no studies available on the effects of teaching EBSE and, as far as we know, only we have gained practice-based experience.

Relevant measures of such phenomena are often collected using semi-structured interviews. Such interviews involve high costs, and the quality of the collected data is related to how the interviews are conducted. Careful planning and conducting of the interviews are therefore necessary, and experiences from interview studies in software engineering should consequently be collected and analyzed to provide advice to other researchers. We have brought together experiences from 12 software engineering studies, in which a total of 280 interviews were conducted. Four areas were particularly challenging when planning and conducting these interviews; estimating the necessary effort, ensuring that the interviewer had the needed skills, ensuring good interaction between interviewer and interviewees, and using the appropriate tools and project artifacts. The paper gives advice on how to handle these areas and suggests what information about the interviews should be included when reporting studies where interviews have been used in data collection. Knowledge from other disciplines is included. By sharing experience, knowledge about the accomplishments of software engineering interviews is increased and hence, measures of high quality can be achieved","PeriodicalId":402415,"journal":{"name":"11th IEEE International Software Metrics Symposium (METRICS'05)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128929714","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}

Given a size estimate, it is usually possible to estimate the effort that will be needed to build this system. The most widely used approach to size estimation is function point analysis (FPA). It is not clear, however, how function points can be reasonably counted for object-oriented requirements specifications. We found that this cannot be done fully automatically, since several constructs of such a representation can be interpreted in various ways in the spirit of FPA, depending on the context. For applying FPA to object-oriented requirements specifications, we defined rules that specify a semi-automatic transformation from an object-oriented requirements model to an FPA model","PeriodicalId":402415,"journal":{"name":"11th IEEE International Software Metrics Symposium (METRICS'05)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127630217","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}
