I started in business back in 1973. When you were conducting it, you picked up the phone, made an appointment, met the person (often times over lunch), discussed the proposition and you moved ahead – or you did not. Today requires us to interact through several different forms and at several different levels. That, in and of itself, is a skill that requires patience, coordination, timing, access and understanding of several specific modes of communication.
When you have a large work-group, comprised of people at all different ages, spread across ten time zones, with varying hardware/software/bandwidth at their disposal. It usually requires someone to step in and ask the question, “are we all speaking the same language here?”
