An examination of the characteristics required by the employees and heads of undertakings of every kind leads to the same conclusions as the foregoing study, which was confined largely to industrial concerns. In the home and in affairs of State, the need for administrative ability is proportional to the importance of the undertaking. Like every other undertaking, the home requires administration, that is to say planning, organization, command, coordination and control. Nothing but a theory of administration, which can be taught and then discussed by everybody, can put an end to the general uncertainty as to proper methods, which exists in the isolation of our households. There is therefore a universal need for a knowledge of administration.
