	title = {The Effects of Diversity in Global, Distributed Collectives: A Study of Open Source Project Success},
	booktitle = {Information Systems Research},
	year = {2012},
	abstract = {Diversity is a defining characteristic of global collectives facilitated by the Internet. Though substantial evidence suggests that diversity has profound implications for a variety of outcomes including performance, member engagement, and withdrawal behavior, the effects of diversity have been predominantly investigated in the context of organizational workgroups or virtual teams. We use a diversity lens to study the success of non-traditional virtual work groups exemplified by open source software (OSS) projects. Building on the diversity literature, we propose that three types of diversity (separation, variety and disparity) influence two critical outcomes for OSS projects: community engagement and market success. We draw on the OSS literature to further suggest that the effects of diversity on market success are moderated by the application development stage. We instantiate the operational definitions of three forms of diversity to the unique context of open source projects. Using archival data from 357 projects hosted on SourceForge, we find that disparity diversity, reflecting variation in participants{\textquoteleft} contribution-based reputation, is positively associated with success. The impact of separation diversity, conceptualized as culture and measured as diversity in the spoken language and country of participants, has a negative impact on community engagement but an unexpected positive effect on market success. Variety diversity, reflected in dispersion in project participant roles, positively influences community engagement and market success. The impact of diversity on market success is conditional on the development stage of the project. We discuss how the study{\textquoteleft}s findings advance the literature on antecedents of OSS success, expand our theoretical understanding of diversity, and present the practical implications of the results for managers of distributed collectives.},

	title = {When Cultures Clash: Participation in Open Source Communities and Its Implications For Organizational Commitment},
	number = {7},
	year = {2011},
	abstract = {Software applications developed within the OSS community have enjoyed tremendous success and for-profit organizations are keen to tap into this significant pool of software development talent (Chesbrough 2003; Feller et al. 2008). Examples companies include Netscape, IBM and Google (Maccormack et al. 2006). These companies seek to benefit from the talent of a global and sometimes voluntary workforce by paying some employees to contribute to OSS projects (Raymond 1999, Shah 2006). This merging of open and traditional software development may cause developer stress based on conflicting OSS community and traditional software development norms. Specifically, developers must balance company intellectual property concerns with the reciprocal and community-based norms that drive OSS development (Stewart and Gosain 2006). When these values are not in sync, contributors that aim to abide by conflicting values may exhibit dysfunctional attitudes. Employee stress with respect to their role can be destructive to organizational outcomes (Maas and Matejka 2009; Aranya and Ferris 1984). This study develops an OSS context specific model that describes the relationship between clashing software development cultures and employee organizational commitment. We leverage the rich OSS literature and the research that focuses on organizational-professional conflict (OPC) to develop hypotheses linking clashing cultures and organizational commitment. These hypotheses are tested using a combination of archival data and a survey of 127 GNOME developers. The findings presented in this paper contribute to OSS literature and offer findings that will enable organizations to more successfully engage OSS communities.},

Using cross-sectional and longitudinal data on a sample of 108 open source projects, this research investigated how the complexity of open source project releases varied throughout the life of the project. Functional data analysis was applied to the release histories of the projects and recurring evolutionary patterns were derived. There were projects that saw little evolution, according to their measures of size and structural complexity. However, projects that displayed some evolution often differed on the pattern of evolution depending on whether size or structural complexity was examined. Factors that contribute to and result from the patterns of complexity were evaluated, and implications for research and practice are presented.},

	title = {The Impact of Person-Organization Fit on Turnover in Open Source Software Projects},

	year = {2010},
	abstract = {Participant turnover in open source software development is a critical problem. Using Schneider{\textquoteright}s (1987) Attraction Selection and Attrition Framework and the notion of Person- Organization fit, we hypothesize about the relationship between a participant{\textquoteright}s fit with an open source project and turnover. Specifically we predict that value fit, needs-supplies fit and demandsabilities fit between a participant and a particular project will have a negative association with participant turnover and that the role of the participant in the project acts a moderator. An empirical study is designed to examine the hypotheses using a combination of survey and archival data. Since for-profit companies are increasingly leveraging open source software development, implications of our findings will be useful for project managers seeking to retain talented contributors in the absence of financial compensation.},

	abstract = {This paper examines the factors that influence the long-term sustainability of FLOSS projects. A model of project sustainability based on organizational ecology is developed and tested empirically. Data about activity and contribution patterns over the course of five years for 2,772 projects registered with SourceForge is analyzed. Our results suggest that the size of the project{\textquoteright}s development base, project age and the size of niche occupied by the project are positively related to the project{\textquoteright}s ability to attract user and/or developer resources. The ability to attract resources is an indicator of the perceived project legitimacy, which in turn is a strong predictor of the project{\textquoteright}s future sustainability. Thus a project{\textquoteright}s ability to attract developer and user resources is shown to play a mediating role between the demographic (size and age) and ecological (niche) characteristics of the project and its future sustainability. Our results support the applicability of tenets of organizational ecology related to the liability of smallness, the liability of newness, and population characteristics (niche size) to the FLOSS development environment. The implications of the results for future research and practice are discussed.},

Several challenges in analyzing the data from software projects are discussed, an approach to overcoming those challenges is described, and preliminary results from the analysis of a sample of open source software (OSS) projects are provided. The results demonstrate the utility of FDA for uncovering and categorizing multiple distinct patterns of evolution in the complexity of OSS projects. These results are promising in that they demonstrate some patterns in which the complexity of software decreased as the software grew in size, a particularly novel result. The paper reports preliminary explorations of factors that may be associated with decreasing complexity patterns in these projects. The paper concludes by describing several next steps for this research project as well as some questions for which more sophisticated analytical techniques may be needed.},
