Currently, open source software (OSS) products have started to become popular in the market as an alternative to traditional proprietary or closed source software. Governments and organizations are beginning to adopt OSS on a large scale and several governmental initiatives have encouraged the use of OSS in the private sector. One major issue for the government and private sector is the selection of appropriate OSS. This paper uses new internal quality characteristics for selecting OSS that can be added to the dimensions of DeLone and McLean information systems’ model. Through this study, the quality characteristics are organized in a two level hierarchy, which list characteristics and sub-characteristics that are interconnected with three main dimensions: system quality, information quality and service quality. These characteristic dimensions are tailored to the criteria having been built from literature study and standard for software quality and guidelines. This paper presents case study results of applying the proposed quality characteristic on eight different open source software that are divided between open source network tools and learning management systems.  相似文献

Until recently, organizations willing to acquire application systems have had no choice but to adopt proprietary software. With the advent of open‐source software (OSS), a new model for developing and distributing software has entered the stage. OSS has evolved from a generally horizontal infrastructure towards more highly visible applications in vertical domains, giving information systems (IS) managers more degrees of freedom in their selection of enterprise application software (EAS). Although a large body of research exists on the relative importance of evaluation criteria for proprietary EAS, the role of OSS in the EAS evaluation process has received little attention so far. To address this research gap, this study represents the first empirical investigation to compare the relative importance of evaluation criteria in proprietary and open‐source EAS selection. Through an online survey, we evaluated the responses of IS managers of 358 organizations to a conjoint study spawning 8592 trade‐off pair comparisons and 3580 purchase evaluations on proprietary and open‐source enterprise resource planning (ERP) and Office software packages. The results show that the relative importance of evaluation criteria significantly varies between proprietary and open‐source ERP systems. Implementation factors such as ease of implementation and support are much more crucial in the evaluation of open‐source than of proprietary ERP systems, which is generally due to IS managers' risk mitigation behaviour. Interestingly, there are no major differences in the ranking of evaluation criteria between proprietary and open‐source Office systems. We conclude our paper with a detailed discussion of our findings and their implications for researchers, companies, EAS vendors and open‐source communities.  相似文献

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.  相似文献

Commercial software companies face many challenges when competing in today’s fast moving and competitive industry environment. Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.  相似文献

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.  相似文献

ContextOpen source software (OSS) is changing the way organizations develop, acquire, use, and commercialize software.ObjectiveThis paper seeks to identify how organizations adopt OSS, classify the literature according to these ways of adopting OSS, and with a focus on software development evaluate the research on adoption of OSS in organizations.MethodBased on the systematic literature review method we reviewed publications from 24 journals and seven conference and workshop proceedings, published between 1998 and 2008. From a population of 24,289 papers, we identified 112 papers that provide empirical evidence on how organizations actually adopt OSS.ResultsWe show that adopting OSS involves more than simply using OSS products. We moreover provide a classification framework consisting of six distinctly different ways in which organizations adopt OSS. This framework is used to illustrate some of the opportunities and challenges organizations meet when approaching OSS, to show that OSS can be adopted successfully in different ways, and to organize and review existing research. We find that existing research on OSS adoption does not sufficiently describe the context of the organizations studied, and it fails to benefit fully from related research fields. While existing research covers a large number of topics, it contains very few closely related studies. To aid this situation, we offer directions for future research.ConclusionThe implications of our findings are twofold. On the one hand, practitioners should embrace the many opportunities OSS offers, but consciously evaluate the consequences of adopting it in their own context. They may use our framework and the success stories provided by the literature in their own evaluations. On the other hand, researchers should align their work, and perform more empirical research on topics that are important to organizations. Our framework may be used to position this research and to describe the context of the organization they are studying.  相似文献

Drawing on social capital theory, we develop a theoretical model aiming to explore how open source software (OSS) project effectiveness (in terms of team size, team effort and team's level of completion) is affected by expertise integration. This in turn is influenced by three types of social capital – relational capital, cognitive capital and structural capital. In addition, this study also examines two moderating effects – the impact of technical complexity on the relationship between cognitive capital and expertise integration, and of task interdependence on the relationship between expertise integration and task completion. Through a field survey of 160 OSS members from five Taiwanese communities, there is support for some of the proposed hypotheses. Both reciprocity and centrality affect expertise integration as expected, but the influence of commitment and cognitive capital (including expertise and tenure) on expertise integration is not significant. Finally, expertise integration affects both team size and team effort, which in turn jointly influence task completion. This research contributes to advancing theoretical understanding of the effectiveness of free OSS development as well as providing OSS practitioners with insight into how to leverage social capital for improving the performance of OSS development.  相似文献

Prior network-based research on open source software (OSS) development has focused on the benefit of network ties and assumed all network ties play the same role. We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader–follower type and follower–leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects.  相似文献

User satisfaction has always been a major factor in the success of software, regardless of whether it is closed proprietary or open source software (OSS). In open source projects, usability aspects cannot be improved unless there are ways to test and measure them. Hence, the increasing popularity of open source projects among novice and non-technical users necessitates a usability evaluation methodology. Consequently, this paper presents a usability maturity model specifically aimed at usability-related issues for open source projects. In particular, the model examines the degree of coordination between open source projects and their usability aspects. The measuring instrument of the model contains factors that have been selected from four of our empirical studies, which examine the perspectives of OSS users, developers, contributors and the industry. In addition to presenting the usability maturity model, this paper discusses assessment questionnaires, a rating methodology and two case studies.  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
