A management information system (MIS) gives business managers the information they need to make decisions and solve problems, while facilitating data from different aspects of a project.[3] Early business computers were used for simple operations such as tracking inventory, billing, sales, or payroll data, with little detail or structure[4] (see EDP). Over time, these computer applications became more complex, hardware storage capacities grew, and technologies improved for connecting previously isolated applications. As more data was stored and linked, managers sought greater abstraction as well as greater detail with the aim of creating significant management reports from the raw, stored data. Originally, the term Management Information System "MIS" described applications providing managers with information about sales, inventories, and other data that would help in managing the enterprise. Over time, the term broadened to include: decision support systems, resource management and human resource management, enterprise resource planning (ERP), enterprise performance management (EPM), supply chain management (SCM), customer relationship management (CRM), project management and database retrieval applications.
The terms Management Information System (MIS), information system, Enterprise Resource Planning (ERP), and information technology management are often confused. Information systems
