理解开发者的合作行为是促进开源社区协作开发的关键一步。已有文献主要对社区成员的加入与迁移展开研究,而对社区中已有开发者之间的实际合作行为关注甚少。主要从开发者的交互关系与个人技能两个角度出发,探析社区已有开发者如何建立新合作以及哪些因素影响他们的合作。应用Sourceforge.net平台公开的数据进行实验,结果表明不同的开发者的偏好合作模式不同,拓扑距离上的优势(“朋友的朋友”关系)对开发者间首次合作的影响不大,开发者之前的合作次数越多越有利于他们 再次建立合作,而开发环境(操作系统)与开发者(管理)经验对合作也有明显的影响。所得结论有助于提高开源社区已有开发者的合作意识,促进社区的稳定与可持续性。 相似文献

This article examines distributed participatory design in open source software (OSS) development. User participation is becoming a relevant topic of research in the OSS development context. Though it has not been examined much to date, the OSS development context has been argued to advocate a particular type of participatory design, which can now be scrutinised in its natural setting as it evolves. Two interpretive case studies on user participation in OSS development are included in this article. The first examines a traditional community OSS development project; the second concentrates on the company OSS development context, the case being a software development unit of a global corporation involved in OSS development. Through analysis of the cases, different forms of participatory design (PD), especially of distributed PD, are identified. Distributed PD is interpreted to include gaining an understanding of users' current practices, redesigning them together with users and gathering feedback from users related to the solutions. Different kinds of roles are available to users, as well as to for intermediaries ‘representing users’. Especially, the importance of online forum-based and intermediary-driven PD is emphasised in this article. Implications for PD and OSS research and practice are considered. 相似文献

In this paper, the evolution of a large sample of open source software systems will be analysed. The evolution of commercial systems has been an issue that has long been a centre of research, thus a coherent theoretical framework of software evolution has been developed and empirically tested, most notably the laws of software evolution. In exploring the evolutionary behaviour of open source systems, these results can serve as a point of reference, allowing to assess if differences exist, or which aspects of open and collaborative development styles have an impact on evolutionary behaviour. The data collection method relying on a large software repository and the respective source code control systems is described, and an overview on the collected data on several thousand projects is given. The evolutionary behaviour is explored using both a linear and a quadratic model, with the quadratic model being shown as better suited. The most interesting fact is that while in the mean the growth rate is linear or decreasing over time according to the laws of software evolution, a significant percentage of projects is able to sustain super‐linear growth. There is a positive relationship between the size of a project, the number of participants, and the inequality in the distribution of work within the development team with the presence of super‐linear growth patterns. On the other hand, there is evidence for a group of projects of moderate size which shows decreasing growth rates, while small projects in general exhibit linear growth.

An information system is typically developed by a team of information systems (IS) professionals. Research shows that teams staffed with the right people are more likely to be effective and efficient. There is a paucity of study that examines the important traits of IS professionals in team contexts. The objective of this research is to identify and understand the important characteristics of good team members in software development projects. We applied an established psychological technique (Repertory Grid) to guide our interviews with 21 experienced IS professionals, who have had extensive experience in software development teams. The comprehensive list of important characteristics was analysed qualitatively using open coding method of grounded theory. Fifty‐nine unique characteristics were identified and classified into eight categories. Among them, attitude/motivation, knowledge, interpersonal/communication skills, and working/cognitive ability were perceived by research participants to be the most important categories. Our study provides a context‐specific (i.e. software development team) evaluation of important characteristics of IS professionals. The results have significant implications for IS recruiting, IS training, IS staffing, and IS human resource management. Our study also supplements the research on management of IS development teams. 相似文献

Abstract This paper presents results from research into open source projects from a software engineering perspective. The research methodology employed relies on public data retrieved from the CVS repository of the GNOME project and relevant discussion groups. This methodology is described, and results concerning the special characteristics of open source software development are given. These data are used for a first approach to estimating the total effort to be expended. 相似文献

Although the development of open source software (OSS) projects is known to be critically dependent on many key factors, the precise contribution of the various user and developer activities toward the development of an OSS project is unknown. Therefore, an empirical study is performed to examine the correlation between the user/developer activities and the state of development of an OSS project. It is shown that certain user/developer activities have a particular efficacy in facilitating OSS project development. The results presented in this study provide an effective approach useful in observing and evaluating the development of OSS projects. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Open source software (OSS) has been developing for more than two decades. It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects. 相似文献

Despite a growing body of research on OSS production, much remains to be learned. One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model.We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant. 相似文献
