need to spend more time than conventional team counterparts being explicit about expectations. This is due to the patterns of behavior and dynamics of interaction which are unfamiliar. Moreover, even in information rich virtual teams using video conferencing, it is hard to replicate the rapid exchange of information and cues available in face-to-face discussions. To develop role clarity within virtual teams, leaders should focus on developing: (a) clear objectives and goals for tasks; (b) comprehensive milestones for deliverables; and (c) communication channels for seeking feedback on unclear role guidance. When determining an effective way of leadership for a culturally diverse team there are various ways: directive (from directive to participatory), transactional (rewarding) or transformational influence. Leadership must ensure effective communication and understanding, clear and shared plans and task assignments and collective sense of belonging in team. Further, the role of a team leader is to coordinate tasks and activities, motivate team members, facilitate collaboration and solve conflicts when needed. This proofs that a team leader's role in effective virtual team management and creating knowledge sharing environment is crucial. Presence and Instruction Virtual team leaders must become virtually present so they can closely monitor team members and note changes that might affect their ability to undertake their tasks. Due to the distributed nature of virtual teams, team members have less awareness of the wider situation of the team or dynamics of the overall team environment. Consequently, as situations change in a virtual team environment, such as adjustments to task requirements, modification of milestones, or changes to the goals of the team, it is important that leaders monitor followers to ensure they are aware of these changes and make amendments as required. The leaders of virtual teams do not possess the same powers of physical observation, and have to be creative in setting up structures and processes so that variations from expectations can be observed well virtually (for instance, virtual team leaders have to sense when "electronic" silence means acquiescence rather than inattention). At the same time, leaders of virtual teams cannot assume that members are prepared for virtual meetings and also have to ensure that the unique knowledge of each distributed person on the virtual team is fully utilized. Virtual team leaders should be aware that information overload may result in situations when a leader has provided too much information to a team member.
