The dynamics of the economic life and the contemporary informational explosion have turned the different decision-making assisting systems into a must. Despite the limitations caused by the impossibility for a computer to perfectly reproduce human reasoning, today, in management, information systems are indispensable tools for the modern manager. Their continual improvement, doubled by the improvement of the calculation technology, provide increased possibilities of taking over ever more comprehensive segments of the reasoning activity carried out by the human decision-maker. We shall note that under the conditions created by the Internet, the information system has set itself free from the enterprise and has even gone beyond the scope of the enterprise, providing a direct connection with banks and providers, and offering the corporate leadership data on the leadership of the modern enterprise is no longer satisfied with operative information; it wants forecasts, it wants to foresee its competitors’ future moves and the future evolution of the market, taking into consideration what is going on at present. For this reason, although no such decision-making support systems have been designed so far, we can state that the modern information systems should look beyond the perimeter of the enterprise.
