Results of research of distinctions between complexes of significant professional and personal qualities of managers of different action areas on studying of levels of optimum development of their competences are presented. The allocated complexes of key professional and personal competences can be a basis for formation and development of competitiveness of managers of these areas of professional activity. Data of the analysed works allowed to establish the general structure of the professionally important competences (PIC) of managers of various fields of activity. In this structure along with the general basis including key professional competences of the manager also differentiating competences for managers of various areas of professional activity are marked out. These characteristics define competitiveness of the manager in each area of work. The cluster analysis of distribution of professional areas of managers on expressiveness of their PIC allowed to distribute their professional requirements into 3 clusters. Cluster distribution of professional and personal competences of managers of various action areas allowed to divide them into 4 clusters. These clusters divide the general structure of professional competence of the manager on levels of its development. The cluster of PIC which have the greatest value for determination of competitiveness of managers from a position of predictive approach to development of professional and personal competence is allocated.
