Autoregressive integrated moving average (ARIMA) models are the most commonly used prediction models in the previous studies on software evolution prediction. This study explores a prediction method based on fuzzy time series for predicting the future commit activity in open source software (OSS) projects. The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems. It is found that the predicted results of the computational method outperform various ARIMA models. Towards the end, a commit prediction model is used for each project to analyse the trends in their commit activity.

This paper aims to analyse the key factors influencing knowledge sharing in open source software projects. Four deep cases are analyzed to develop a conceptual framework based on within-case and cross-case analysis. In terms of data collection, online (including skype meeting, email, email-list, IRC, forum, group meeting, etc) and offline (mainly with face-to-face discussion) activities are two major platforms. The research framework is that distributed innovation (independent variable) will influence shared knowledge (medium variable) and continue to affect the performance of OSS projects (dependent variable). During distributed innovation, developers located on the supply side will affect the shared knowledge from the aspects of Participative Motivation, Social Network and Organizational Culture. Meanwhile, users situated on the demand side will function from the view of user innovation.

There exists two types of developers in open source software (OSS) projects: 1) Committers who have permission to commit edited source code to the Version Control System (VCS), 2) Developers who contribute source code but cannot commit to the VCS directly. In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer. Finally, we develop a committer-identification model to assist OSS projects identifying future committers.

This study relies on Media Synchronicity Theory and Social Network Analysis to analyze how the structure of collaboration networks change when collaborating teams become temporally dispersed. The empirical test of hypotheses using ordinary least squares with archival data from 230 open source software projects shows that the collaboration structure networks of more temporally dispersed teams are sparser and more centralized, and these associations are stronger in those teams exhibiting higher relative performance.

A comprehensive set of governance mechanisms and dimensions were investigated to identify combinations of mechanisms that are effectively used together in on-going volunteer-based open source software (OSS) projects. Three configurations were identified: Defined Community, open Community, and Authoritarian Community. Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team. The results provide guidance for practitioners about how to combine 19 identified governance mechanisms into effective project governance that stimulates productive participation.

Nowadays, many software projects are partially or completely open-source based. There is an increasing need for companies to participate in open-source software (OSS) projects, e. g., in order to benefit from open source ecosystems. OSS projects introduce particular challenges that have to be understood in order to gain the benefits. One such challenge is getting newcomers onboard into the projects effectively. Similar challenges may be present in other self-organised, virtual team environments. In this paper we present preliminary observations and results of in-progress research that studies the process of onboarding into virtual OSS teams. The study is based on a program created and conceived at Stanford University in conjunction with Facebook's Education Modernization program. It involves the collaboration of more than a dozen international universities and nine open source projects. More than 120 students participated in 2013. The students have been introduced to and supported by mentors experienced in the participating OSS projects. Our findings indicate that mentoring is an important factor for effective onboarding in OSS projects, promoting cohesion within distributed teams and maintaining an appropriate pace.

The migration of legacy monolith systems toward a microservice architecture is a large-scale, nontrivial technical activity and investment. This shift would be infeasible without the use of robust underlying software that can sustain a big part of this work and sort the complexities involved. A myriad of open source software (OSS) projects are available in the community for this purpose, however, many companies may remain reluctant to adopt them as the cornerstone for their new evolved systems that can work at scale. Ownership, security, quality concerns, or support confidence are widely common reasons. Furthermore, these concerns are intensified when the OSS is to take part in critical sections of the evolved system. Using a complex case study from Zalando, this article aims to give some light to both researchers and practitioners into the use of OSS to drive this evolution, and the impact that the OSS can have on the adopting system.

software development is extremely complex, requiring collaboration between teams and developers who collaborate on various tasks;these activities lead to the generation of an implicit developer social network (DSN). The authors' aim to understand the development process in terms of collaboration between developers. In this work, they conducted an empirical study on mining social collaboration patterns of DSNs for open source software projects based on an integrated approach involving the identification of global and local collaboration patterns among developers based on social network analysis. The bug tracking system-based DSN (BTS-DSN) is chosen as an example over the other DSNs since it incorporates larger collaboration activities and actors. The empirical results show that the DSNs, specifically BTS-DSN, exhibits three different coordination pattern levels (Plan, Aware, and Reflexive) based on their collaboration activities. The mean time to repair metric proves that the Reflexive level occupies the fastest bug fixing time, then the Plan level comes secondly, and lastly the Aware level. In addition, each level group shows different collaboration behaviours among developers;thus, this information can be useful as a resource for better understanding of developer collaboration and collaboration awareness.

We apply survival analysis methods to a dataset of publicly-available software projects in order to examine the attributes that might lead to their inactivity over time. We ran a Kaplan-Meier analysis and fit a Cox Proportional-Hazards model to a subset of software Heritage Graph Dataset, consisting of 3052 popular Python projects hosted on GitLab/GitHub, Debian, and PyPI, over a period of 165 months. We show that projects with repositories on multiple hosting services, a timeline of publishing major releases, and a good network of developers, remain healthy over time and should be worthy of the effort put in by developers and contributors.
