This context provides an opportunity to examine how the use of technological support to span temporal and organizational discontinuities affects decision-making processes. 258 software-modification decision episodes were collected from the public emailing lists of six Free/Libre Open Source Software (FLOSS) projects over a span of five years. Six decision-making paths were identified as 1) short-cut decision-making path; 2) implicit-development decision-making path; 3) implicit-evaluation decision-making path; 4) normative decision-making path; 5) dynamic decision-making path; and 6) interrupted/delayed decision-making path. We suggest that the nature of the tasks and the affordances of the technology used reduce the need for explicit coordination, resulting in a broader range of possible decision processes than are observed in face-to-face groups.}, attachments = {https://crowston.syr.edu/sites/crowston.syr.edu/files/Decision\%20Making\%20Paths\%20in\%20Self\%20Organizing\%20Technology\%20Mediated\%20Dist.pdf}, author = {Li, Qing and Heckman, Robert and Kevin Crowston and James Howison and Allen, Eileen E. and Eseryel, U.

We compare 3 analysis approaches to identify the core: the named list of developers, a Bradford{\textquoteright}s law analysis that takes as the core the most frequent contributors and a social network analysis of the interaction pattern that identifies the core in a core-and-periphery structure. We apply these measures to the interactions around bug fixing for 116 SourceForge projects. The 3 techniques identify different individuals as core members; examination of which individuals are identified leads to suggestions for refining the measures. All 3 measures though suggest that the core of FLOSS projects is a small fraction of the total number of contributors.}, keywords = {FLOSS}, attachments = {https://crowston.syr.edu/sites/crowston.syr.edu/files/CoreAndPeripheryInFreeLibre.pdf}, author = {Kevin Crowston and Kangning Wei and Li, Qing and James Howison} } @proceedings {Heckman:2006b, title = {Emergent decision-making practices in technology-supported self-organizing distributed teams}, year = {2006}, address = {Milwaukee, WI, 10{\textendash}13 Dec}, abstract = {We seek to identify work practices that make technology-supported self-organizing distributed (or virtual) teams (TSSODT for short) effective in producing outputs satisfactory to their sponsors, meeting the needs of their members and continuing to function.

We examined developer interaction data from three active and successful FLOSS projects and used content analysis to identify the coordination mechanisms used by the participants. We found that there were similarities between the FLOSS groups and the reported practices of the proprietary project in the coordination mechanisms used to manage task-task dependencies.
