The impact of information technology (IT) companies are probably in the form of gigantic proportions. With the advent of the Internet, the traditional methods of business have changed significantly, as evidenced by the emergence of electronic commerce. In addition, adding a greater use of the World Wide Web for different applications through IT. Time and space is exceeded and the “world is flat” now. Globalization will continue and is the result of increased competition between operators. This shows that information technology can change business! Aware of the profound impact of information technology, IT, of course, requires a greater need for business and strategic management focus. Particularly interesting is the use of IT in strategic management. In this context, the role of information technology expands, it changes the role of the traditional role of an information system that more and more leadership. Three key concepts must be taken in connection with this fact. This is a strategic management, information technology (IT) and Information System (GIS). The following descriptions explain the connection between First, the relationship between information technology and management information system concepts.The. The traditional view that the computer processes information technology activities, the information held. From this perspective, only the information systems of different positions. Hardware and software are important implications for the function. Strategic planning requires decisions to be made that not taking place. Therefore, use of IT systems for the selection of the data impossible under the only decisions that are arranged between the nature.The Second, strategic management and information management.

This means that the flow of information has been designed so that the data are available if needed. Take the example of a strategic information system to collect information about booking a flight through the exchange of information between the organization and its airline alliances, ticket offices and travel agencies.
