There are five functions of management; planning, organizing, staffing, directing, and controlling. All five functions are very closely related and they tend to blend together. They can be integrated in many ways and to be honest I am not sure they can exist without integrating.
Planning is the basic function of management and it's primary focus is setting organizational goals. Organizing is the act of bringing together different departments to actively achieve organizational goals. Staffing is the act of manning the structure. Directing is influencing, guiding, supervising, motivating so that the organizational goals can be achieved. The last function is controlling. This is basically setting performance standards, making sure they are followed and achieved and taking corrective action if they are not.
