The results of the scientific research presented in the doctoral dissertation represent contribution to economic sciences both in theoretical and in the applicable sense. In the theoretical sense, the contribution of economic sciences refers to: a) the development of scientific thinking about management in general and in particular regarding compensating management in modern economic conditions in market economies; b) the development of scientific thinking in the creation of appropriate models of Croatian compensation systems that could help to create successful business strategies of Croatian economic entities in the IT sector in order to be able to maintain the existing markets and penetrate the new market; c) the development of innovation and innovative business in the IT segment in order to achieve sustainable competitive advantages. Contributions to the doctoral dissertation of economics in a meaningful sense relate to empirical findings on key aspects in human resources management, rewarding systems, and innovation support, with the aim of improving the competitiveness of an economic entity. Similarly, based on theoretical insights and explanations about compensation management, competitive advantages, prerequisites and boosting innovations, critical analyzes of current Croatian realities and the results of empirical research in a propulsion area such as IT, a number of possible applications are suggested in economic practice. The purpose of company's strategic positioning is to improve its competitive edge by increasing its profitability and better disposition of organization resources. It is about selecting a strategy of cost advantage or a strategy of differentiation and their combination by applying focus strategies, but also by supporting connectivity and / or information management strategies. Based on the recommendations set out in the PhD dissertation, the proposed strategies for Croatian economic entities - and not only in the IT sector - are aimed at achieving their competitive advantages on the domestic and global markets, with optimum positioning and management of the most important resource - people.
