The involvement of managers and decision makers in all aspects of information systems is a major factor for organizational success, including higher profits and lower costs. Some of the benefits business organization seek to achieve through information systems include: better safety, competitive advantage, fewer errors, greater accuracy, higher quality products, improved communications, increased efficiency and productivity, more efficient administration, superior financial and managerial decision making. Keywords: information system, management, software, organization JEL Code: D80 1. Introduction An IS can be defined as a set of interrelated elements or components that collect, manipulate and store and disseminate data and information as well as a feedback mechanism. Information systems take much more time and money to implement than originally anticipated or the completed systems does not work properly. Because so many information systems are trouble-ridden, designers, builders, and users of information systems should understand why they succeed or fail. Management Information Systems (MIS) began to develop in the 1960s and are characterized by the use of information systems to produce managerial reports. In the most cases, these early reports were produced periodically (daily, monthly, or yearly). Because they occurred on a planned basis, they were called scheduled reports and helped managers to perform their duties. Other types of reports also developed during the early stages of management IS are demand reports. These reports were developed to give decision makers certain information upon request. Exception reports describe unusual or critical situation and are produced if a certain condition exists. By the 1970s and 1980s dramatic improvements in technology resulted in IS that were les expensive but more powerful. The computer system could be used to support all aspects of decision making. This type of system, called a decision support system (DSS), supports and assists all aspects of problem specific decision making. A DSS can provide immediate assistance in solving complex problems and goes beyond a traditional MIS, which merely produced reports; a DSS can help by suggesting alternatives and assisting final decision making.
