Metcalfe s Law states that the value of a telecommunications network increases exponentially with its size. In the 1970s communications were largely limited to telephone calls, telexes, and telegrams; on average, executives had to deal with fewer than 1,000 of them a year from people other than coworkers. That number rose dramatically as new technologies spread: We estimate that executives today receive an average of 30,000 external communications every year. And the more senior an executive, the more time subordinates must spend filtering, organizing, and coping with all those messages and conversations.
