Leadership is the activity of influencing people to cooperate toward some goal which they come to find desirable. - Ordway Tead

Many leaders are in the first instance executives whose primary duty is to direct some enterprise or one of its departments or sub-units...
It remains true that in every leadership situation the leader has to possess enough grasp of the ways and means, the technology and processes by means of which the purposes are being realized, to give wise guidance to the directive effort as a whole...
In general the principle underlying success at the coordinative task has been found to be that every special and different point of view in the group affected by the major executive decisions should be fully represented by its own exponents when decisions are being reached. These special points of view are inevitably created by the differing outlooks which different jobs or functions inevitably foster. The more the leader can know at first hand about the technique employed by all his group, the wiser will be his grasp of all his problems...
But more and more the key to leadership lies in other directions. It lies in ability to make a team out of a group of individual workers, to foster a team spirit, to bring their efforts together into a unified total result, to make them see the significance of the particular task each one is doing in relation to the whole.

[Committees are] a tool of the democratic, knowledge-pooling, and desire-harmonizing process which cannot be otherwise forwarded. And when committees fail, as they sometimes do, it is because the limits to their role are not clearly understood or because they have not benefited by proper leadership from the chairman.

The leader is one who knows with greater than average strength of intuition what he wants to get done and where he wants to go. 'The world stands aside to let pass the man who knows whither he is going.'
This means that he possesses clarity and precision as to the objectives, purposes or aims that he desires for himself and his group, and that he holds these deeply enough and permanently enough to see them well on the way to being realized. Purposefulness to be effective requires that the aims are: (1) definite; (2) readily communicable to others; (3) potentially attractive to others; and (4) vigor¬ously, persistently and enthusiastically sustained by the leader.
