Information Systems researchers have not been slow to embrace this combination of method and data. Such systems increasingly provide "digital trace data" that provide new research opportunities. Yet digital trace data are substantively different from the survey and interview data for which network analysis measures and interpretations were originally developed. This paper examines ten validity issues associated with the combination of data digital trace data and social network analysis methods, with examples from the IS literature, to provide recommendations for improving the validity of research using this combination. %B Journal of the Association for Information Systems %V 12 %N 12 %& Article 2 %> https://flosshub.org/sites/flosshub.org/files/HowisonSNADigitalTraceData-WorkingPaper.pdf %0 Journal Article %J IEE Proceedings Software %D 2002 %T Open Source Software Projects as Virtual Organizations: Competency Rallying for Software Development %A Kevin Crowston %A Barbara Scozzi %K competencies %K competency rallying %K coordination %K project success %K sourceforge %K virtual organizations %X The contribution of this paper is the identification and testing of factors important for the success of Open Source Software (OSS) projects. We present an analysis of OSS communities as virtual organizations and apply Katzy and Crowston's (2000) competency rallying (CR) theory to the case of OSS development projects. CR theory suggests that project participants must develop necessary competencies, identify and understand market opportunities, marshal competencies to meet the opportunity and manage a short-term cooperative process. Using data collected from 7477 OSS projects hosted by the SourceForge system (http://sourceforge.net/), we formulate and test a set of specific hypotheses derived from CR theory. %B IEE Proceedings Software %V 149 %P 3–17 %G eng %> https://flosshub.org/sites/flosshub.org/files/crowston.pdf
