"I've Got a Situation and Would Appreciate Your Experience": An Extra-Organizational Virtual Community of Practice for Independent Professionals

Virtual Communities of Practice CoPs that are launched and managed by organizations have been amply documented in KM literature, but extra-organizational virtual CoPs have received little coverage. This study performs an ethnography of an extra-organizational Usenet-based CoP of tax professionals, using a longitudinal Social Network Analysis to map a tight-knit long-lived community and identify its members. The result is a naturalistic description of the ways in which the Wenger dimensions of Mutual engagement, Joint enterprise and Shared repertoire manifest themselves in day-to-day interactions in an online CoP. The study highlights how energetic voluntary participation by members produces a successful long-lived virtual CoP, even in the absence of organizational KM or IT resources. For independent professionals, extra-organizational virtual CoPs can provide a powerful support group and the means to constantly update their personal competence. For organizations intent on developing formalized CoPs, these results are a useful reminder that member commitment is the ultimate driver of a CoP's success.
