Consequently, telecommunications software is required to have high reliability. Many previous studies define the classification fault prone in terms of fault counts. This study defines fault prone as exceeding a threshold of debug code churn, defined as the number of lines added or changed due to bug fixes. Previous studies have characterized reuse history with simple categories. This study quantified new functionality with lines of code. The paper analyzes two consecutive releases of a large legacy software system for telecommunications. We applied discriminant analysis to identify fault prone modules based on 16 static software product metrics and the amount of code changed during development. Modules from one release were used as a fit data set and modules from the subsequent release were used as a test data set. In contrast, comparable prior studies of legacy systems split the data to simulate two releases. We validated the model with a realistic simulation of utilization of the fitted model with the test data set. Model results could be used to give extra attention to fault prone modules and thus, reduce the risk of unexpected problems.","PeriodicalId":441362,"journal":{"name":"Proceedings of ISSRE '96: 7th International Symposium on Software Reliability Engineering","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114571787","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}

Various symmetric combinations of NVP and AT have also been suggested. We take the view that one can insert an AT at virtually any point in a suitably constructed multi-channel computation graph and that judicious placement of ATs will lead to cost-effective reliability improvement. Hence, as a general framework for the creation, representation, and analysis of combined NVP-AT schemes, we introduce MTV graphs, and their simplified data-driven version called DD-MTV graphs, composed of computation module (M), acceptance test (T), and voter (V) building blocks. Previous NVP-AT schemes, such as consensus recovery blocks, recoverable N-version blocks, and N-self-checking programs can be viewed as special cases of our general combining scheme. Results on the design and analysis of new NVP-AT schemes are presented and the reliability improvements are quantified. We show, e.g., that certain, somewhat asymmetric, combinations of M, T, and V building blocks can lead to higher reliabilities than previously proposed symmetric arrangements having comparable or higher complexities.","PeriodicalId":441362,"journal":{"name":"Proceedings of ISSRE '96: 7th International Symposium on Software Reliability Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128697068","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}

Musa et al. (1991). It represents the average detectability of the faults in software. Other parameters that control reliability growth are software size and execution speed of the processor which are both easily evaluated. The fault exposure ratio thus presents a key challenge in our quest towards understanding the software testing process and characterizing it analytically. It has been suggested that the fault exposure ratio may depend on the program structure, however the structuredness as measured by decision density may average out and may not vary with program size. In addition FER should be independent of program size. The available data sets suggest that FER varies as testing progresses. This has been attributed partly to the non-randomness of testing. We relate defect density to FER and present a model that can be used to estimate FER. Implications of the model are discussed. This model has three applications. First, it offers the possibility of estimating parameters of reliability growth models even before testing begins. Secondly, it can assist in stabilizing projections during the early phases of testing when the failure intensity may have large short term swings. Finally, since it allows analytical characterization of the testing process, it can be used in expressions describing processes like software test coverage growth.","PeriodicalId":441362,"journal":{"name":"Proceedings of ISSRE '96: 7th International Symposium on Software Reliability Engineering","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124387630","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 cases reviewers use checklists to guide their analysis during review sessions. However, valuable, checklist-based code-reviews have the principal shortcoming of their high costs due to lack of supporting tools enabling at least partial automation of typical multiple appearing rules. This paper describes an approach towards semi-automation of some steps of individual review processes based on checklists. The method proposed is interactive, i.e. reviewers will be enabled to actualize, extend, and check the consistency and redundancy of their checklists. The basic idea underlying the approach is the usage of a rule-based system, adapting concepts of the compiler theory and knowledge engineering, for acquisition and representation of knowledge about the program. Redundant and conflicting knowledge about the program under study is recognized and solved by means of an embedded truth maintenance system. As a result of fault diagnosis, rules for fault classification are used. Software reliability models are applied to validate the results of each review session. The approach has shown promising preliminary results in analyses of conventional C-programs developed in the automotive industry.","PeriodicalId":441362,"journal":{"name":"Proceedings of ISSRE '96: 7th International Symposium on Software Reliability Engineering","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114651605","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}
