“…Prominent works focus on co-located or distributed work groups (Dourish and Bly, 1992;Gupta et al, 2009), project teams (Evaristo et al, 2004;, consortia, alliances, and joint ventures (Ibrahim and Ribbers, 2009;Miles and Snow, 1995). Although less emphasis has been placed on individuals who do not work together under such hierarchical structures, we argue that it is important that managers understand how their decisions play a critical role (Dubé et al, 2006) in how workers self-organize as ''communities of communities'' (Brown and Duguid, 1991, p. 54). We also believe that it is timely to focus on mobility in a discussion of community-based knowledge sharing (Wasko and Faraj, 2000), as collaboration across organizational boundaries (e.g., Adebanjo and Michaelides, 2009;Elaluf-Calderwood et al, 2005;Kim, 2000;Lefebvre and Lefebvre, 2002;Wattal et al, 2010) increasingly happens through mobile IT.…”
