Cost estimates are needed throughout the software lifecycle to determine feasibility of software projects and to provide for appropriate allocation or reallocation of available resources. To assess the effect of imprecise evaluations, a comprehensive sensitivity analysis was performed on a major cost estimation model, COCOMO II. Results of this analysis are described and explicated in this paper. To reduce risk of drawing biased conclusions, three different methods for sensitivity analysis were employed: the mathematical analysis of the estimating equation, Monte Carlo simulation, and error propagation. The results of the first two methods are very consistent and confirm expected highest sensitivity of the model to the imprecision of the size estimate. Error propagation allows determination of the combined impact of imprecision in multiple inputs and it is therefore most valuable from the practical point of view. The results obtained by this technique also indicate very strong sensitivity to the imprecision in size estimates. A possible way to cope with imprecise information in software cost estimation is also indicated.","PeriodicalId":165815,"journal":{"name":"Proceedings Eighth IEEE Symposium on Software Metrics","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131494791","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}

For example, several studies have identified clear empirical relationships between class-level coupling and the fault-proneness of the classes. A common way to quantify the coupling is through static code analysis. However, the resulting static coupling measures only capture certain underlying dimensions of coupling. Other dependencies regarding the dynamic behavior of software can only be inferred from run-time information. For example, due to inheritance and polymorphism, it is not always possible to determine the actual receiver and sender classes (i.e., the objects) from static code analysis. This paper describes how several dimensions of dynamic coupling can be calculated by tracing the flow of messages between objects at run-time. As a first evaluation of the proposed dynamic coupling measures, fairly accurate prediction models of the change proneness of classes have been developed using change data from nine maintenance releases of a large SmallTalk system. Preliminary results suggest that dynamic coupling may also be useful for developing prediction models and tools supporting change impact analysis. At present, work on developing a dynamic coupling tracer and ripple-effect prediction models for Java programs is underway.","PeriodicalId":165815,"journal":{"name":"Proceedings Eighth IEEE Symposium on Software Metrics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133243039","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}

Redirecting development effort toward reversing system degeneration takes extra effort and delays the release of the next version. The value of an improved architecture is clear to technical staff, but it is often difficult to convince upper management that the extra effort is necessary. Improved architecture is intangible and does not translate into visible user features that can be marketed. Due to a lack of representative metrics, technical staff has problems arguing that stopping degeneration is indeed necessary and that the effort will result in an improved architecture that will pay off. We believe that architectural metrics would give technical staff better tools to argue their case. This paper defines and uses a set of architectural metrics and outlines a process for analyzing architecture to support such an argument. The paper reports on a case study from a project where we restructured the architecture of an existing client-server system written in Java while adding new functionality. The modules of the existing version of the system were \"library-oriented\" and had a disorganized communication structure. The new architecture is based on components and utilizes the mediator design pattern. The goal of the study is to evaluate the new architecture from a maintainability perspective.","PeriodicalId":165815,"journal":{"name":"Proceedings Eighth IEEE Symposium on Software Metrics","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115273218","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}

A module-order model (MOM) uses an underlying quantitative prediction model to predict this rank-order. This paper compares performances of module-order models of two different count models which are used as the underlying prediction models. They are the Poisson regression model and the zero-inflated Poisson regression model. It is demonstrated that improving a count model for prediction does not ensure a better MOM performance. A case study of a full-scale industrial software system is used to compare performances of module-order models of the two count models. It was observed that improving prediction of the Poisson count model by using zero-inflated Poisson regression did not yield module-order models with better performance. Thus, it was concluded that the degree of prediction accuracy of the underlying model did not influence the results of the subsequent module-order model. Module-order modeling is proven to be a robust and effective method even though both underlying prediction may sometimes lack acceptable prediction accuracy.","PeriodicalId":165815,"journal":{"name":"Proceedings Eighth IEEE Symposium on Software Metrics","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127894080","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}
