The aim of the paper is to compare effects and barriers of e-organizations and traditional organizations. The authors claim that global strategies of organization can be realized more completely and more easily thanks to virtual organizations. In the first part of the paper the authors present a comparative analysis of management systems of e-organizations and traditional organizations. They concentrate on the research conducted on MBA studies and among extra-mural students. In the second part they analyze 50 companies examined by the students of the final year of the Economics Department at the Lazarski School of Commerce and Law in Warsaw during their workshops called 'Meetings with heads of companies'. An e-organization is an attractive form of organization. In comparison to a traditional organization it eliminates a lot of barriers connected with its establishment and further stages of its life cycle - functioning and managing it. On the one hand, an effective functioning of a traditional organization is mostly influenced by management styles used and appropriate organizational structure. On the other hand, a virtual organization eliminates these problems to the minimum. A virtual organization is able to function both locally and globally thanks to development of information technology. The development of e-organizations guarantees an increase in competitiveness of small and large organizations on the global markets.
