Software Product Lines (SPL) and Service-Orientation (SO) are two strategies that focus on different goals, but they both use software reuse as their main principle. SPL encompass a family of software systems developed from reusable assets, while SO is a way of developing service-based applications, providing reusable business functionalities. In the combination of SPL and SO, a key aspect is the understanding about the use of variability mechanisms for realizing variabilities in different levels of granularity (e.g., components, services, service-orchestrations) addressed in a technology specific way and improve modularity, complexity, and Separation of Concerns (SoC) of reusable assets. In this paper, we present a quantitative case study for evaluating the modularity, complexity, SoC and stability of reusable core assets using distinct technologies for implementing them, and an initial decision model based to guide software engineers on choosing suitable technologies. © 2010 IEEE.

In software product lines (SPL), scoping is a phase responsible for capturing, specifying and modeling features, and also their constraints, interactions and variations. The feature specification task, performed in this phase, is usually based on natural language, which may lead to lack of clarity, non-conformities and defects. Consequently, scoping analysts may introduce ambiguity, inconsistency, omissions and non-conformities. In this sense, this paper aims at gathering evidence about the effects of applying an inspection approach to feature specification for SPL. Data from a SPL reengineering project were analyzed in this work and the analysis indicated that the correction activity demanded more effort. Also, Pareto's principle showed that incompleteness and ambiguity reported higher non-conformity occurrences. Finally, the Poisson regression analysis showed that sub-domain risk information can be a good indicator for prioritization of sub-domains in the inspection activity.© 2012 Elsevier Inc.

Software maintenance starts as soon as the first artifacts are delivered and is essential for the success of the software. However, keeping maintenance activities and their related artifacts on track comes at a high cost. In this respect, change request (CR) repositories are fundamental in software maintenance. They facilitate the management of CRs and are also the central point to coordinate activities and communication among stakeholders. However, the benefits of CR repositories do not come without issues, and commonly occurring ones should be dealt with, such as the following: duplicate CRs, the large number of CRs to assign, or poorly described CRs. Such issues have led researchers to an increased interest in investigating CR repositories, by considering different aspects of software development and CR management. In this paper, we performed a systematic mapping study to characterize this research field. We analyzed 142 studies, which we classified in two ways. First, we classified the studies into different topics and grouped them into two dimensions: challenges and opportunities. Second, the challenge topics were classified in accordance with an existing taxonomy for information retrieval models. In addition, we investigated tools and services for CR management, to understand whether and how they addressed the topics identified. Copyright © 2013 John Wiley & Sons, Ltd.
