The term management refers to a system of knowledge and practices in order to establish an effective organization. People who operate in this area are called managers. The activities that management deals with are management functions. Management functions consist of planning, organizing, staffing, leading and controlling. Each of these functions is important but leading is considered to be one of the most important functions of management. The goals direct the actions of the organization at all levels (strategic, tactical and operational). Setting and determining the goals at all levels of management is one of the most important tasks of management. Leading is the essential function of management because there is no other function of such the importance of the management success. Other management functions can be passed to others while leading is the only function which can not be passed to others, not even partially. One can only be a true leader only if he/she possesses the best leading skills. Leading is influencing people in a way that they readily seek to achieve their objectives. The style of management is extremely important for creating the successful company management and achieving good results. Style is reflected by how leaders stimulate their employees to carry out a specific task. Autocratic leadership style presents a style in which all the leadership power lies in the hands of only one person, and that person has unlimited power to make decisions. The democratic leadership style appears opposing the autocratic style. This style is characterized by including the subordinates in decision-making processes that are essential for a successful business. Also mentioned are laissez-fair style and the theory " X " and " Y".
