All of Vora's points are accurate, but one stuck out at us more than others: "Lack of trust is one of the biggest killers in a virtual team environment. The way you manage a team tells a lot about how much you trust them."
Tells a lot? It tells everything.
When a team is away, leaders tend to get insecure and start micro-managing. They just push decisions to their teams, rather than involving them in the decision making. This works against building a culture of trust and empowerment.
We've talked about the people process before and just how important it is to model the right behaviors in your own leadership to facilitate a strong team, whether virtual or not. Remember, though, the other legs of the stool; modeling positive leadership for your people is directly supported by team-friendly processes that communicate clearly, and technology that supports communication and strategic objectives. The strongest teams emerge when all three -- the people, process, and technology variables -- are functioning at their strongest and supporting the weight of the project equally. With strong teams comes respect and trust, not only in leadership, but in one another.
