Answer to Question 2
Answer: Virtual teams are groups of geographically dispersed coworkers who interact using a combination of telecommunications and information technologies to accomplish an organizational task.
The main challenges virtual teams face are often people related. Challenges include building trust, cohesion, and team identity, and overcoming the isolation among team members.
Success therefore depends on human resource management actions. In particular, train virtual team members in leadership, conflict management, and meetings management, and to respond swiftly to virtual teammates. Be scrupulous about answering e-mails and being positive. Select virtual team members using behavioral and situational interviews, where they describe how they'd respond to illustrative virtual team situations. Use current virtual team members to help recruit and select new team members.
