Management primarily means the process of planning, organization, human resource management, management, and control, as well as organizing and managing tasks, resources and reserves, a process aimed at the achievement of a given objective. Leadership is the process of directing the behavior of others towards achieving a goal, where directing means getting people to behave in a certain way and follow a certain path. Under the leadership style we mean the synthesis of individual methods, procedures, and techniques of management of managers in certain types of organizations, so it is important for a leader to know about the different leadership styles and to try to use a variety of styles when to do so by the demands of the situation. Knowledge obtained during the theoretical part of the work has been applied to company Studio Interior LTD from Zagreb, where they observed and described leadership style as a function in process of management.
