Our review is organized around an input-mediator-output-input (IMOI) model. We start with a description of the articles selected for the review. We then discuss findings of this literature categorized into issues pertaining to inputs (e.g., member characteristics, technology use and project characteristics), processes (software development and social processes), emergent states (e.g., trust and task related states) and outputs (e.g. team performance, FLOSS implementation and project evolution). Based on this review, we suggest research questions, including methodological and theoretical issues, to guide future inquiry in this area.},

	abstract = {There is an exciting natural match between social network analysis methods and the growth of data sources produced by social interactions via information technologies, from online communities to corporate information systems. 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.},

Based on prior work on leadership in distributed groups, we identify leaders with those who make the highest level of contribution to the group and assess the degree of leadership by measuring centralization of communications. We compare the dynamics of leadership in two FLOSS projects, one more and one less effective. We find that in both projects, centralization was higher in developer-oriented communications venues than in user-oriented venues, suggesting higher degrees of leadership in developer venues. However, we do not find a consistent relation between centralization and effectiveness. We suggest that SNA can instead be useful for identifying interesting periods in the history of the project, e.g., periods where the leadership of the project is in transition.},

We also expanded upon the original results by applying different criteria for evaluating the rate of new software releases for sustainability of project activity. We discuss the points of convergence and divergence from the original work from these extensions of the classification, and their implications for studying FLOSS development using archival data.

	abstract = {This paper presents a novel method and algorithm to measure the size of an open source project{\textquoteright}s user base and the level of potential user interest that it generates. Previously unavailable download data at a daily resolution confirms hypothesized patterns related to release cycles. In short, regular users rapidly download the software after a new release giving a way to measure the active user base. In contrast, potential new users download the application independently of the release cycle, and the daily download figures tend to plateau at this rate when a release has not been made for some time. An algorithm for estimating these measures from download time series is demonstrated and the measures are examined over time in two open source projects.

Unlike previous research focused on the influence of synchronous ICTs, our study examines how group decisions are made in asynchronous communication channels. Our inductive qualitative analysis of 360 decision episodes of six FLOSS projects revealed diversity in decision-making practices, which appears to be related to differences in project effectiveness and task type. We also find that standardization of procedures through CSCW tools transforms the nature of some software development work from non-routine to standard procedure.},

Recently we have begun a second phase, which is to introduce another established principle of eResearch, that of broader collaboration through shared workflows accessing these data repositories. To provide an example of the potential value of this principle, we are replicating seminal FLOSS papers using eResearch approaches. This paper describes research outcomes and lessons learned from translating published literature into eResearch workflows.},
