The main goal of this paper was to determine the connection between social networking and business success of an individual manager. The theoretical part of the paper defines networking as a managerial competence that can, if recognized, developed and promoted, provides a manager with a comparative advantage in career development and achieving business success. By defining the social network, its constituent parts and by explaining the dynamics of creating relationships within the network, one gets an insight into the structure of the network itself and network relations. Particular emphasis is placed on weak ties that connect individuals as those that potentially provide access to non-redundant data and information that can lead to new knowledge and insights. These information can be crucial in achieving business success. Contrary to the advantages provided by weak ties within the managerial network, the concept of social capital is explained through the definition of trust, support and reciprocity that exist in the relationship between actors within the network and whose creation and development increases the quality of relationships between actors.Empirical research among managers in the public sector explores the types of connections which prevail in management networks, the content and quality of these ties and also managers' perceptions of the impact of self-defined social networks on their own business success, as they understand it.
