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.

Time is the scarcest resource, and unless it is managed, nothing else can be managed. The analysis of one’s time, moreover, is the one easily accessible and yet systematic way to analyze one’s work and to think through what really matters in it.

Everything requires time. It is the one truly universal condition. All work takes place in time and uses up time. Yet most people take for granted this unique, irreplaceable, and necessary resource. Nothing else, perhaps, distinguishes effective executives as much as their tender loving care of time.
