Managers are in constant action. Virtually every study of managers in action has found that they “switch frequently from task to task, changing their focus of attention to respond to issues as they arise, and engaging in a large volume of tasks of short duration.”3 Mintzberg observed CEOs on the job to get some idea of what
they do and how they spend their time. He found, for instance, that they averaged 36 written and 16 verbal contacts per day, almost every one of them dealing with a distinct or different issue. Most of these activities were brief, lasting less than nine minutes.
