One has to sit down with a knowledge worker and think through with him what should be done and why, before one can even know whether he is doing a satisfactory job or not. And this is time-consuming.

Since the knowledge worker directs himself, he must understand what achievement is expected of him and why. He must also understand the work of the people who have to use his knowledge output. For this, he needs a good deal of information, discussion, instruction—all things that take time. And contrary to common belief, this time demand is made not only on his superior but equally on his colleagues.

Whenever I see a senior executive asserting that more than half his time is under his control and is really discretionary time which he invests and spends according to his own judgment, I am reasonably certain that he has no idea where his time goes. Senior executives rarely have as much as one quarter of their time truly at their disposal and available for the important matters, the matters that contribute, the matters they are being paid for. This is true in any organization except that in the government agency the unproductive time demands on the top people tend to be even higher than they are in other large organizations.

To be effective, every knowledge worker, and especially every executive, therefore needs to be able to dispose of time in fairly large chunks. To have small dribs and drabs of time at his disposal will not be sufficient even if the total is an impressive number of hours.

This is particularly true with respect to time spent working with people, which is, of course, a central task in the work of the executive. People are time-consumers. And most people are time-wasters.

To spend a few minutes with people is simply not productive. If one wants to get anything across, one has to spend a fairly large minimum quantum of time. The manager who thinks that he can discuss the plans, direction, and performance of one of his subordinates in fifteen minutes—and many managers believe this—is just deceiving himself. If one wants to get to the point of having an impact, one needs probably at least an hour and usually much more. And if one has to establish a human relationship, one needs infinitely more time.
