DEFINATION A management information system (MIS) is a system designed to collect, store and transmit data in the form of information needed to perform management functions in an organization. MIS helps an organization obtain information and manage its business efficiently. The management information system is different from other information systems. It is because they are used to analyze and facilitate strategic and operational activities. In the beginning, the management information system (MIS) was designed to support management decision making. Over time, the term has expanded and includes many resources such as resource management and human resource management, supply chain management, customer relationship management and many others. The Management Information System (MIS) produces information products that support many decision-making needs of managers, staff and business professionals. The reports, views and responses produced by management information systems provide information that these decision makers have specified in advance as adequately meeting their information needs. Such pre-defined information products meet the information needs of decision makers at the operational and tactical levels of the organization who are faced with more structured types of decision situations. For example, sales managers rely heavily on sales analytics reports to evaluate performance differences between salespeople selling the same types of products to the same types of customers. They have a pretty good idea of ​​what kind of sales performance information (by product line, sales territory, customer, salesperson, etc.) they need to manage sales performance effectively. Furthermore, MIS is also used by managers and other decision makers fo...... middle of paper...... meet their needs. Marketing led the way and was followed by manufacturing and finance. Most current attention is focusing on the executive level and the human resources function. An MIS consists of two types of information production subsystems. Reporting software provides information in the form of periodic and special reports. Mathematical models provide information in the form of simulation results. MIS is an organization-wide commitment to a quality information resource. MIS is particularly useful for identifying problems and helping managers understand them so they can be solved.
