Time is fragmented. Managers have acknowledged from antiquity that they never seem to have enough time to get all those things done that need to be done. In the latter years of the twentieth century, however, a new phenomenon arose: demand for time from those in leadership roles increased, while the number of hours in a day remained constant. Increased work hours was one reaction to such demand,
but managers quickly discovered that the day had just 24 hours and that working more of them produced diminishing marginal returns. According to one researcher, “Managers are overburdened with obligations yet cannot easily delegate their tasks.
As a result, they are driven to overwork and forced to do many tasks superficially. Brevity, fragmentation, and verbal communication characterize their work.”Mintzberg, H. (1990). “The Manager’s Job: Folklore and Fact.” Harvard Business Review, March–April 1990, p. 167.
Values compete and the various roles are in tension. Managers clearly cannot satisfy everyone. Employees want more time to do their jobs; customers want products and services delivered quickly and at high quality levels. Supervisors want more money to spend on equipment, training, and product development;
shareholders want returns on investment maximized. A manager caught in the middle cannot deliver to each of these people what each most wants; decisions are often based on the urgency of the need and the proximity of the problem.
The job is overloaded. In recent years, many North American and global businesses were reorganized to make them more efficient, nimble, and competitive. For the most part, this reorganization meant decentralizing many processes along with the wholesale elimination of middle management layers. Many managers who survived such downsizing found that their number of direct reports had doubled.
Classical management theory suggests that seven is the maximum number of direct reports a manager can reasonably handle. Today, high-speed information technology and remarkably efficient telecommunication systems mean that many managers have as many as 20 or 30 people reporting to them directly.
