Bug fix time prediction models have been used to predict the fix-time of newly reported bugs in order to help out the developer during the triaging process by prioritizing which bugs to fix first. While constructing these prediction models, we deal with large data sets. It is very likely that these data sets contain outliers that would affect the predictive power of the prediction models. For example,...
Predicting bug fix-time is an important issue in order to assess the software quality or to estimate the time and effort needed during the bug triaging. Previous work has proposed several bug fix-time prediction models that had taken into consideration various bug report attributes (e.g. severity, number of developers, dependencies) in order to know which bug to fix first and how long it will take...
Software architecture is a key discipline in software engineering as it performs a central role in many modern software development paradigms. For an evolving complex architecture, assessing the change impact for the components considering all maintenance scenarios is a difficult problem. In this paper, we present a methodology to conduct sensitivity analysis of maintainability-based risk factors...
Software Product Line aims at improving productivity and decrease realization times by gathering the analysis, design and implementation activities of a family of systems. Evaluating the quality attributes for SPL architectures is very crucial especially architecture maintainability as SPL are expected to have longer lifetime span. Aspect-orientation offers a modularization way by separating crosscutting...
A software product spends more than 65% of its lifecycle in maintenance. Software systems with good maintainability can be easily modified to fix faults. We define maintainability-based risk as a product of two factors: the probability of performing maintenance tasks and the impact of performing these tasks. In this paper, we present a methodology for assessing maintainability-based risk in the context...
Development of software systems utilizes only 20%-40% of the overall project cost; the rest is consumed by maintenance. Systems with poor maintainability are difficult to modify and to extend. Maintainability based risk is defined as a product of two factors: the probability of carrying out maintenance tasks and the impact of these tasks. The decision of adopting a single architecture over others...
The study of software architectures is gaining importance due to its role in various aspects of software engineering such as product line engineering, component based software engineering and other emerging paradigms. With the increasing emphasis on design patterns, the traditional practice of ad-hoc software construction is slowly shifting towards pattern-oriented development. Various architectural...
