Design a set of best practices for the leadership of cross-cultural, virtual teams

Design a set of best practices for the leadership of cross-cultural, virtual teams. Consider the following questions in your design:

What are the challenges posed by cultural diversity among team members? Pay particular attention to the ways in which cross-cultural teams are unique.

How important is an understanding of the individual cultures represented on the team to successful team management? Should your best practices be culture-specific or apply to cross-cultural management in general? Cite specific examples in your analysis.

What are the human resource considerations for designing cross-cultural and/or virtual teams? How are considerations for these two groups similar or different?
