Management Information System (MIS) is a computer-based system that processes data into information to support management, operations, and decision-making in an organization. There are different types of MIS like executive support systems, decision support systems, and transaction processing systems. Developing an effective MIS involves preliminary investigation, requirements analysis, systems design, procurement, and implementation. Key benefits of MIS include improved decision-making, cost savings, and increased productivity. Components of an MIS in a non-profit include a client database, work planning application, financial system, and personnel information system.
