"Just as the chief executive is aided by staff officials in the carrying out of his program, so also do subordinate line executives establish normal and continuous relationships with staff officials in the development of their work. If the line official cannot satisfy the staff assistant as to the necessity of his proposal, then the door of the executive's office must be open to him and he should be free to state his recommendation, explain any points of difference he has with the staff assistant, and leave the decision to his superior. As a general proposition also, if the decision is close, the chief executive should decide in favor of the line official, since presumably he knows his own needs better than any staff assistant because he is closer to them and is responsible for results. If the chief executive fails to back him up then he is bound to feel that his judgment is in question. This injures his initiative and self-confidence-as well as his confidence in his superior-and is to be avoided if possible. Ordinarily, however, if both line and staff men are competent, they will be able to reach an agreement and make a unified recommendation. Close decisions are rare when all the facts are known."
