Preprocessors are a common way to implement variability in software. They are used in numerous software systems, such as operating systems and databases. Due to the ability of preprocessors to enable and disable code fragments, not all parts of the program are active at the same time. Thus, programmers and tools need to handle the interactions resulting from annotations in the program. With our Eclipse-based...
The evolution dynamics of a software ecosystem depend on the activity of the developer community contributing to projects within it. Both social and technical changes affect an ecosystem's evolution and the research community has been investigating the impact of these modifications over the last few years. Existing studies mainly focus on temporary modifications, often ignoring the effect of permanent...
Agile software development approaches are becoming mainstream as organizations recognize that their delivery methodology has to be nimble and flexible to accommodate new technologies and evolving customer requirements. However, large organizations depend on a global software delivery model wherein software teams are geographically distributed, and such an environment seems unsuited for Agile to succeed...
We introduce Polinode, an online tool for performing network analysis. Polinode is aimed at commercial and non-commercial users alike and supports both research-related use cases as well as teaching network analysis to students. One of its primary advantages is that it is web-based. It therefore doesn't require any software downloads and opens up new avenues for collaboration and the incorporation...
We all want to be associated with long lasting ideas; as originators, or at least, expositors. For a tyro researcher or a seasoned veteran, knowing how long an idea will remain interesting in the community is critical in choosing and pursuing research threads. In the physical sciences, the notion of half-life is often evoked to quantify decaying intensity. In this paper, we study a corpus of 19,000+...
Trust is quintessential to safety in a network and is the epitome of security. Trust management schemes have been researched and implemented in Wireless Sensor Networks (WSNs) to provide an added advantage over and above the cryptographic security mechanisms. Each trust management scheme deals with the concept of trust and its evaluation in a unique manner. This uniqueness in approach is achieved...
There is a growing interest in socio-technical networks that encompass people, process and technology. They capture connections among technical artifacts and human resources. Existing studies have shown that social networks among resources that collaborate to work on a business process instance have an impact on the performance of the instance. Hence, the social network among the resources should...
Empirical analysis of software repositories usually deals with linear histories derived from centralized versioning systems. Decentralized version control systems allow a much richer structure of commit histories, which presents features that are typical of complex graph models. In this paper we bring some evidences of how the very structure of these commit histories carries relevant information about...
Determining contributors' expertise, role, and individual importance are fundamental for assessing their impact on a software project. Currently-used expertise metrics are agnostic to contributor roles and can lead to incorrect characterizations. To address these issues, we operationalize contributor expertise and role. First, we revisit current expertise metrics and show that their use bundles many...
In this position paper we discuss the necessity of using User-Centered Design (UCD) methods in order to design collaborative software for the intelligence community. We discuss a number of studies of collaboration in the intelligence community and use this information to provide some guidelines for collaboration software.
Software architecture design is known to be driven by the quality attributes we may want to satisfy. Among them, modifiability plays an important role since software maintenance takes the lion's share in the software development costs. However, to successfully maintain a legacy system, the latter must be sufficiently understood so that the maintenance team will not introduce new bugs when correcting...
This position paper reflects on recent work that sought to make positive changes to the IEEE Requirements Engineering conference (RE), and on twenty years of requirements engineering (REng) research. We question the values that seem to underpin RE, and offer what we believe are more appropriate values. We argue that these new values would result in better alignment between research and the needs of...
This paper describes the development of a collaborative social platform to support innovation process management. The Drupal based platform accommodates different types of innovation processes (also called waves or idea contests), enhances collaboration and eases management. The main contribution lies on the gathering of context parameters which helps enterprises on the detection of critical success...
The emerging empirical literature on Open Source communities indicates that a majority of code writing and communication activity is concentrated with a few contributors, the “core” (maintainers). However, these communities allow and encourage participation from anybody, the “periphery”. The focus of this work is on explaining how distributed communities solve software problems through the participation...
Agile software development and project management methodologies, such as Scrum and Extreme Programming, have become very popular in quickly delivering quality Functional Requirements (FRs). However, agile project management methodologies have not adequately captured planning and prioritization activities for crosscutting concerns and non-functional requirements in agile practices. This research proposes...
Many software developments involve collaborations of developers across the globe. This is true for both open-source and closed-source development efforts. Developers collaborate on different projects of various types. As with any other teamwork endeavors, finding compatibility among members in a development team is helpful towards the realization of the team's goal. Compatible members tend to share...
Flexible interactions in complex social and service-oriented collaboration systems increasingly demand for automated adaptation techniques to optimize partner discovery and selection. Today, applications of complex service-oriented systems can be found in crowd sourcing environments. In such environments, collaborations are typically short-lived and strongly influenced by incentives and actor behavior...
Empirical studies show that mismatches between design and organizational structures may cause expensive inter-team communication costs. However, prevailing design models and metrics are not designed for identifying independent, globally distributable task assignments, and do not account for organizational structure. Our research objectives are to develop design-centric theories, models, and measures...
