The inculcation of belief in the real existence of a common purpose is an essential executive function. - Chester Irving Barnard

It is in the nature of a leader’s work that he should be a realist and should recognize the need for action, even when the outcome cannot be foreseen, but also that he should be idealist and in the broadest sense pursue goals some of which can only be attained in a succeeding generation of leaders. Many leaders when they reach the apex of their powers have not long to go, and they press onward by paths the ends of which they will not themselves reach. In business, in education, in government, in religion, again and again, I see men who, I am sure, are dominated by this motive, though unexpressed, and by some queer twist of our present attitudes often disavowed. Yet, ‘Old men [and old women] plant trees’... to shape the present for the future by the surplus of thought and purpose which we now can muster seems the very expression of the idealism which underlies such social coherence as we presently achieve, and without this idealism we see no worthy meaning in our lives, our institutions, or our culture.

An organization is a subordinate system of a specific larger system, the cooperative system, whose components are physical, biological, and personal systems. The relations with other organizations... are outside this specific cooperative system. Other organizations are a part of the social environment of the organization. It is for this reason I have used the phrase "complex of organizations" rather than "system." Usually the most significant relationships of a unit organization are those with the specific cooperative system of which it is a part. It is this system which primarily and on the whole in most instances determines the chief conditions of the organization's existence.

The making of decisions, as everyone knows from personal experience, is a burdensome task. Offsetting the exhilaration that may result from correct and successful decision and the relief that follows the termination of a struggle to determine issues is the depression that comes from failure, or error of decision, and the frustration which ensues from uncertainty.
