Open source software licenses: Strong-copyleft, non-copyleft, or somewhere in between?

Studies on open source software (OSS) have shown that the license under which an OSS is released has an impact on the success or failure of the software. In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.     

User acceptance model of open source software

The development and implementation of open source software (OSS) is one of the most current topics within the academic, business and political environments. Traditionally, research in OSS has focused on identifying individual personal motives for participating in the development of an OSS project, analyzing specific OSS solutions, or the OSS movement, itself. Nevertheless, user acceptance towards this type of technology has received very little attention. For this reason, the main purpose of the current study is to identify the variables and factors that have a direct effect on individual attitude towards OSS adoption. Therefore, we have developed a technological acceptance model on behalf of the users towards a solution based on OSS. For this development, we have considered the technology acceptance model. Findings show that OSS is a viable solution for information management for organizations.     

Understanding OSS development in communities: the perspectives of ideology and knowledge sharing

This study aims to understand why open source software (OSS) developers contribute and how their dispersed efforts are controlled to lead to viable outputs. Drawing on theories related to ideology and information sharing, a model is proposed and tested empirically. We found that OSS values are positively associated with collaborative elaboration and communication competence, which in turn affect the performance of OSS task in terms of task completion. Our results also delineate the relationship among OSS norms, collaborative elaboration and source credibility, and task completion. This research contributes to advancing theoretical understanding of OSS performance as well as providing OSS practitioners with guidelines on how OSS communities use OSS ideology to achieve better performance.     

Competency rallying in electronic markets: implications for open source project success

This paper studies the success of Open Source Software (OSS) projects in attracting developer interest and achieving project efficiency. The focus of our study is on examining the relationship between the four sets of capabilities proposed in the Theory of Competency Rallying (TCR) and the success of OSS projects. The data collected from 607 OSS projects mainly confirm that the capabilities proposed in the TCR are necessary for the success of OSS projects. The results of this study show that in order to succeed, OSS projects should constantly identify their market??s quality and functionality needs. Ability of OSS project managers to know which developers possess certain skills required to meet a particular market need is also found to be critical. Another capability that is recognised to be crucial in predicting project success is the ability of OSS developers in effectively addressing market needs and continuously learning from such experiences. Finally, the ability of stakeholders involving in addressing a particular market need to efficiently collaborate and fulfil that specific market need is found to be another essential capability required for OSS projects to succeed. Implications of the results for practitioners and the research community are presented.     

Users’ perception of open source usability: an empirical study

The number of open source software (OSS) users has increased in recent years. No longer are they limited to technically adept software developers. Many believe that the OSS market share could increase tremendously provided OSS had systems that were easier to use. Although examples of good usable open source software exist, it is agreed that OSS can be made more usable. This study presents an empirical investigation into the impact of some key factors on OSS usability from the end users’ point of view. The research model studies and establishes the relationship between the key usability factors from the users’ perspective and OSS usability. A data set of 102 OSS users from 13 open source projects of various sizes was used to study the research model. The results of this study provide empirical evidence by indicating that the highlighted key factors play a significant role in improving OSS usability.     

The influence of project initiators’ person-to-person followership on project popularity in open source communities: The role of reach and importance

Person-to-person (P2P) followership is an important aspect of major open source software (OSS) development platforms. In this age of social media platforms, P2P followership has significantly shaped the way users engage in OSS development by facilitating the establishment of connections among OSS users. Despite the prevalence of P2P followership, less is known about the impact of OSS project initiators’ P2P followership nodes on their project popularity. This is a particularly important gap considering the low rate of OSS project success. We posit that OSS project initiators derive information and influence benefits from the quantity and connectivity of their P2P followership nodes, explaining the popularity of the projects initiated. We determine the connectivity of OSS project initiators’ P2P followership nodes based on the nodes’ reach and importance. To test the hypotheses, we use a large panel dataset collected over 24 months from GitHub. The findings indicate that the quantity of OSS project initiators’ P2P followership nodes including followers and followees has a positive effect on their project popularity. Moreover, such an effect is mostly dependent on the connectivity of the OSS project initiators’ P2P followership nodes in such a way that highly connected P2P followership nodes do not impact influence benefits but they increase information benefits. We discuss the theoretical and practical implications of our findings.     

Adoption of open source software in organizations: A socio-cognitive perspective

Open source software (OSS) is an important trend in the information technology adoption landscape. It has received considerable attention in the scientific literature, but mostly in the professional press. In fact, there is much debate over its actual commercial and organizational value. Since the public discourse accompanying an IT may influence adoption decisions, it is important to consider IT specialists’ perceptions of the discourse on OSS. In this study, we investigated the relationship between IT specialists’ profiles, IT specialists’ reception of the public discourse on OSS, and their organizations’ receptivity to OSS. Drawing on the socio-cognitive perspective of IT innovation adoption and the organizing vision theory, a survey of 271 IT specialists was conducted to examine these issues. Our results indicate that a majority of IT specialists in our sample are rather neutral about the OSS concept conveyed in the public discourse. However, our sample also comprises respondents with more extreme perceptions who can be classified as either supporters or detractors. Our results indicate that detractors have more years of experience but have been less exposed to OSS than supporters, and that IT specialists’ perceptions of the OSS concept are positively associated with their organizations’ openness to OSS adoption and, to a lesser extent, with the existence of an organizational policy that favors OSS adoption. Altogether, our findings provide strong support for the organizing vision theory and the idea that the popularity of an IT innovation concept favors the adoption of the material IT innovation in organizations. By providing a preliminary test of a nomological network of IT specialists’ perceptions of the OSS concept, our study offers insights as to why organizations may or may not take OSS into account in their software procurement decisions.     

Has open source software been institutionalized in organizations or not?

ContextAlmost a decade ago, researchers in information systems and analysts of the information technology (IT) industry were predicting a bright future for open source software (OSS). Recent examples appear to lend support to this, but there exist many detractors of OSS and resistance to the transformation it creates. Thus, it is relevant to take a closer look at the institutionalization of OSS.ObjectiveThis paper evaluates the extent of OSS institutionalization in organizations. A practice or innovation is said to be institutionalized when it is taken-for-granted and its use becomes the norm.MethodDrawing on institutional theory, the underlying concept of organizing vision and the rhetorical theory of diffusion of innovations, we analyze OSS institutionalization through the observation of the evolution of the public discourse about OSS and, simultaneously, the observation of the rate of adoption or diffusion of OSS in organizations.ResultsOSS has become institutionalized for many back-end applications and is gradually becoming institutionalized for some front-end applications, mainly in small and medium enterprises but also in organizations in the financial, publishing, education, government and public sectors. Using the rhetorical theory of diffusion of innovations in tandem with the concept of organizing vision, we provide a deep understanding of the institutionalization of OSS by showing that it has not only diffused among organizations, but is also taken-for-granted in thought and social action. The positive tone and prominence of the public discourse on OSS have an important role to play in its institutionalization.ConclusionThe institutionalization of OSS in organizations cannot be underestimated by IT and business executives as well as key players in the IT industry. Future research efforts should be pursued and directed toward the institutionalization of particular OSS applications in a variety of industries and geographic regions.     

Open source software success: Measures and analysis

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.
