Barnard(1996-1961) published his pioneering book The Functions of the Executive, in 1938, over sixty years ago. Yet, while Barnard's book is universally praised, it has had little practical impact. Communication for Barnard was vague and general. It was human relationships, and personal. However, what makes communications effective at the workplace is that they are focused on something outside the per-son. They have to be focused on a common task and on a common challenge. They have to be focused on the work.——《Management Challenges for the 21st Century》Chapter 4.
