"The meaning that I have given to the word administration and which has been generally adopted, broadens considerably the field of administrative science. It embraces not only the public service but enterprises of every size and description, of every form and every purpose. All undertakings require planning, organization, command, co-ordination and control, and in order to function properly, all must observe the same general principles. We are no longer confronted with several administrative sciences but with one alone, which can be applied equally well to public and to private affairs and whose principal elements are today summarized in what we term the Administrative Theory."

“In my opinion, it is the industry concerned which should have the chief say in the question of the amount of theoretical training required. It is the industry which uses the products of the schools, and, like every consumer, it has the right to make its wishes known.”

“Administration, which calls for the application of wide knowledge and many personal qualities, is above all the art of handling men, and in this art, as in many others, it is practice that makes perfect. This is one of the reasons why we should release our future engineers for practical work as early as possible; there are many drawbacks to staying too long at school.”

“Management plays a very important part in the government of undertakings: of all undertakings, large or small, industrial, commercial, political, religious or other. I intend to set forth my ideas here on the way in which that part should be played.”

“a minister has twenty assistants, where the Administrative Theory says that a manager at the head of a big undertaking should not have more than five or six.”

“The technical and commercial functions of a business are clearly defined, but the same cannot be said of the administrative function. Not many people are familiar with its constitution and powers; our senses cannot follow its workings - we do not see it build or forge, sell or buy - and yet we all know that, if it does not work properly, the undertaking is in danger of failure.”

“means both to assess the future and make provision for it.”
