	abstract = {Maintenance is one of the most effort consuming activities in the software development lifecycle. Efficient maintenance within short release cycles depends highly on the underlying source code structure, in the sense that complex modules are more difficult to maintain. In this paper we attempt to unveil and discuss relationships between maintenance productivity, the structural quality of the source code and process metrics like the type of a release and the number of downloads. To achieve this goal, we developed a Bayesian Belief Network (BBN) involving several maintainability predictors and three managerial indices for maintenance (i.e., duration, production, and productivity) on 20 open source software projects. The results suggest that maintenance duration depends on inheritance, coupling, and process metrics. On the other hand maintenance production and productivity depend mostly on code quality metrics.

	address = {Cham},
	abstract = {Issue tracking systems are used, in most software projects, but in particular in almost all free open source software, to record many different kinds of issues: bug reports, feature requests, maintenance tickets and even design discussions. Identifying which of those issues are bug reports is not a trivial task. When researchers want to conduct studies on the bug reports, managed by a software development project, first of all they need to perform this identification.
The job for researchers here is very different from the bug triaging that researchers do. In the latter case, people with a considerate experience in the project make a decision based on the information available at that time (maybe just a short comment by some user), asking, if needed, for more details. In the former case, researchers usually have not that experience in the project, but they have at their use all the information produced, until the moment the issue was closed. This may include not only all comments and actions on the issue tracking system, but for example, discussions about a fix in the code review system, or the final fixing patch in the source code management system. Having all that information conveyed to the researchers, in an easy, flexible and quick way, accelerates and makes their decision process much more reliable. It simplifies large scale manual analysis of issues (in hundreds or thousands), helping researchers to ensure that they are really working with what they intend to work: bug reports.
This paper presents a tool designed to solve exactly the problem of providing the researchers with all the relevant information needed to decide whether an issue corresponds to a bug report or not. The tool uses information extracted automatically from the projects repositories. It offers a web-based interface which allows collaboration, traceability and transparency of the identification of bug reports. All this makes the process easier, faster, and more reliable.},

We performed two action research cycles based on the Kanban method. This paper has two main contributions; first, it describes a real world situation, where Kanban is applied to a FOSS project, and second, it suggests two new Kanban practices. These two methods are targeted specifically at FOSS projects and their characteristics.

We compare successful and unsuccessful projects on volume of communication by core (committer) and peripheral community members and on use of inclusive pronouns as an indication of efforts to create intimacy among team members. An innovation of the paper is that use of inclusive pronouns is measured using natural language processing techniques. We find that core and peripheral members differ in their volume of contribution and in their use of inclusive pronouns, and that volume of communication is related to project success.

It is particularly challenging in Free and Open Source Software (FOSS) ecosystems, in which hundreds of loosely connected developers and their projects need to be coordinated to release software to a schedule. To better understand this process and its challenges, we analyzed over two and half years of communication in the GNOME ecosystem and studied developers{\textquoteright} interactions. We cataloged communication channels, categorized high level communication and coordination activities in one of them, and triangulated our results by interviewing developers. We found that a release schedule, influence instead of direct control, and diversity are factors that impact positively the release process in the GNOME ecosystem. Our results can help organizations build better large-scale teams and show that research focused on individual projects might miss important parts of the picture.

As yet, how these relationships form and evolve is not understood extensively. This article presents a longitudinal case study of a smartphone startup that founded its early product development strategy on reliance on feedback from its customers through a web based question and answer forum. With this, the company managed to extend values typical for open source communities to support development of its proprietary software. Our main findings include that the challenge in similar settings lies in striking the right balance between the open and the proprietary {\textendash} while overt openness may risk the competitive advantage of a company, leaving too much behind closed boundaries can create unnecessary friction in the relationship.

The overarching goal of the study is to establish how organisations contribute to open standards development through editorship. Specifically, the focus is on open standards development in W3C. Through an analysis of editorship for all W3C recommendations we contribute novel findings concerning organisational involvement and collaboration, and highlight contributions from different types of organisations and countries for headquarter of each organisation. We make three principal contributions. First, we establish an overall characterisation of organisational involvement in W3C standardisation. Second, we report on organisational involvement in W3C standardisation over time. Third, we establish organisational collaboration in W3C standardisation through social network analysis.

In aiming to increase efficiency and effectiveness of debugging and bug-fixing for concurrent software, a deep understanding of concurrency bugs, their frequency and fixing-times would be helpful. Similarly, to design effective tools and techniques for testing and debugging concurrent software understanding the differences between non-concurrency and concurrency bugs in real-word software would be useful. This paper presents an empirical study focusing on understanding the differences and similarities between concurrency bugs and other bugs, as well as the differences among various concurrency bug types in terms of their severity and their fixing time. Our basis is a comprehensive analysis of bug reports covering several generations of an open source software system. The analysis involves a total of 4872 bug reports from the last decade, including 221 reports related to concurrency bugs. We found that concurrency bugs are different from other bugs in terms of their fixing time and their severity. Our findings shed light on concurrency bugs and could thereby influence future design and development of concurrent software, their debugging and testing, as well as related tools.

	abstract = {Previous studies on issue tracking systems for open source software (OSS) focused mainly on requests for bug fixes. However, requests to add a new feature or an improvement to an OSS project are often also made in an issue tracking system. These inquiries are particularly important because they determine the further development of the software. This study examines if there is any difference between requests of the IBM developer community and other sources in terms of the likelihood of successful implementation. Our study consists of a case study of the issue tracking system BugZilla in the Eclipse integrated development environment (IDE). Our hypothesis, which was that feature requests from outsiders have less chances of being implemented, than feature requests from IBM developers, was confirmed.

	abstract = {Women are underrepresented in the IT sector. But the situation in FLOSS (free, libre, open source software) development is really extreme in this respect: past publications and studies show a female participation of around 2 \% to 5 \% and have shed some light into this problem. In this paper, we give an update the state of knowledge to the current situation of gender in FLOSS, by analyzing the results of surveying more than 2,000 contributors to FLOSS projects in 2013, of which more than 200 were women. Our findings confirm that women enter the FLOSS community later than men, do primarily other tasks than coding, participate less if they have children, and have slightly different reasons to enter (and to stay in) the development communities they join. However, we also find evidence that women are joining FLOSS projects in higher numbers in recent years, and that the share of women devoting few hours per week to FLOSS and full-time dedication is higher than for men. All in all, comparing our results with the ones from the 2000s, the context of participation of women in FLOSS has not changed much.

	abstract = {The ability to create high-quality software artifacts that are usable over time is one of the essential requirements of the software business. In such a setting, open source software offers excellent opportunities for sustainability. In particular, safeguarding mechanisms against planned obsolescence by any single actor are built into the definition of open source. The most powerful of these mechanisms is the ability to fork the project. In this paper we argue that the possibility to fork serves as the invisible hand of sustainability that ensures that code remains open and that the code that best serves the community lives on. Furthermore, the mere option to fork provides a mechanism for safeguarding against despotic decisions by the project lead, who is thus guided in their actions to consider the best interest of the community.},

	abstract = {The software stack opened under Open Source Software (OSS) licenses is growing rapidly. Commercial actors have released considerable amounts of previously proprietary source code. These actions beg the question why companies choose a strategy based on giving away software assets? Research on outbound OSS approach has tried to answer this question with the concept of the {\textquotedblleft}OSS business model{\textquotedblright}. When studying the reasons for code release, we have observed that the business model concept is too generic to capture the many incentives organizations have. Conversely, in this paper we investigate empirically what the companies{\textquoteright} incentives are by means of an exploratory case study of three organizations in different stages of their code release. Our results indicate that the companies aim to promote standardization, obtain development resources, gain cost savings, improve the quality of software, increase the trustworthiness of software, or steer OSS communities. We conclude that future research on outbound OSS could benefit from focusing on the heterogeneous incentives for code release rather than on revenue models.

The promise of community-style development, innovation and cost savings drive the wider adoption of OSS in companies. However, it is still difficult to institutionalize the open and agile culture of sharing innovation especially into larger departmentalized organizations. The aim of this research paper is to investigate the characteristics of one successful OSS development implementation approach limited inside a company (Inner source). Based on our data, we argue that there are possibilities for employing OSS as a new kind of development process within a company and leveraging thus the innovation potential inside the company.

	abstract = {Open source software is a phenomenon that has potential to change the traditional patterns of business behavior. Research committed so far has not evaluated the entire scale of potential changes, which is the purpose of this explorative thesis. Previous literature on the subject can be divided into history of the phenomenon, explaining the nature of the phenomenon, and a more general discussion about strategies and business models in the software business. By using these theories this thesis provides a framework for analysing the entire phenomenon. The framework is put to use in the empirical part. Data consist of interviews of experts in the field. An analysis of the data is done using narrative methods. The analysis yield eleven narratives that describe the phenomenon. Four of the narratives reveal effects. On the basis of the responses gathered, open source software can change competition environment, customer expectations, the importance of competence, and platform thinking.},
