INTRODUCTIONThe globalization of business competition and a growing need for customer responsiveness in the past few decades have caused an increasing number of firms to undergo dramatic organizational changes (Miles & Snow, 1992). Organizations transform to networks by flattening organizational structure and establishing inter-organizational links (Davidow & Malone, 1992). This change has promoted contemporary firms to coordinate activities that span geographical and organizational boundaries (Townsend et al., 1998). It has also increased the need for utilizing decentralized, specialized knowledge and expertise (Alavi & Tiwana, 2002;Boutellier, 1998;Penrose, 1959). Virtual teams have emerged to allow organizations to overcome these geographical boundaries and to address the emerging knowledge needs (Powell et al., 2004;Workman, 2007).Virtual teams constitute essential structures in today's organizations (Siebdrat et al., 2009).
An internal virtual workforce survey of twelve hundred employees in Intel Corporationreveals that approximately 70 percent of the Intel workforce collaborates with people in different time zones without meeting face to face (Intel Corporation, 2004). Accenture, an international IT systems consulting firm, rests its viability on the performance of "customerintimate" project teams coordinated among dispersed sites (Accenture., 2005 ). Virtual teams form an essential part of today's organizations with important implications for teamwork and collaboration.A crucial aspect of virtual teams is the knowledge process among the team members. In fact, the main driver for building virtual teams is the prospect of integrating the dispersed knowledge and expertise of the team members (Alavi & Tiwana, 2002;Boutellier, 1998).However, while virtual teams are established to support knowledge integration it has been recognized that the virtual collaboration environment inhibits the team's knowledge 3 processes. The geographic dispersion and the reliance on information technologies hinder team members to create, transfer, store and apply knowledge (Alavi & Tiwana, 2002;Cramton, 2001;Griffith et al., 2003). Studies in innovation management (Ahuja, 2000) and organizational learning (Walsh, 1995) highlight how the distributed nature of cognition and the diversity of knowledge in team settings creates challenges for team learning and knowledge processes. These challenges become even more pronounced when the interaction among teams are virtual (Alavi & Tiwana, 2002).Virtual teams are in a "catch-22" situation: the opportunities of integrating dispersed knowledge promotes the emergence of virtual teams; at the same time virtual teams are arguably less capable of identifying and leveraging the collective knowledge of their members than traditional teams are. Recognizing this paradox is highly important for virtual team members as effective knowledge exchange and utilization is not achieved until the team has id...
