The topic of this paper and the research subject is: Management functions in selected judo club and the method of the paper is analysis. Analysing management functions enables the creation of an image about existence of management in a firm, its coverage and the way it is applied. This paper was written to compare theoretical facts about management and real everyday practice. After detailed analysis of management functions it was concluded that it is possible to do business without professional manager and his team. However, choosing between professional and non-professional approach to management has a great impact on a quality of running a business. In this paper I will explain management functions on the example of Judo Club '' Dubrovnik1966''. This club was founded in 1966 in Dubrovnik, and its founder was Andrija Habulin who started the developement of judo in Dubrovnik-Neretva County. This club changed its name several times. Its first name was Nacui, later it became Dubrovnik and after that its name changed into Dubrovačka banka (after its main sponsor) and later it's been known as Dubrovnik1966. After many years of work and development, the club gained trust of European Judo Union which encouraged the club to organize many international cups. The aim of this paper is to inform the reader with basic functions of management and by combining the theoretical starting point with the research part try to realize in what way and to what extent are these functions significant for the development of a company. Reference literature has been used as well as the official web sites.
