Proper selection of persons to perform managerial work (in various forms of ownership) is an important initial step, and after proper selection, one should continuously work with persons who will perform that work, monitor them, guide and work on their career development. When choosing a leader, one must take into account the knowledge he should possess, desirable traits (intellectual, voluntary and emotional personality traits), attitudes, the degree of authority he enjoys and the nature of functioning -the group he works with to solve problems. Important personality traits, which should be taken into account when choosing a person for managers are: temperament, interests, character and abilities, and they can be determined to some extent on the basis of certain qualitative and quantitative indicators. Numerous knowledge from practice, although various sciences and scientific disciplines provide a good basis for high efficiency and effectiveness, show that there are many managerial (managerial) problems, and there are few good managers. The aim of this paper is to provide certain theoretical knowledge that provides a good basis for improving operational practices aimed at properly identifying candidates for managers, their proper education and training throughout their working lives and career development.
