Management Information System (MIS) is a computer-based system that processes data into information to support operations, management, and decision-making across departments in an organization. MIS provides managers with tools to organize, evaluate, and efficiently manage their departments. It integrates hardware, software, data, people, and procedures to facilitate planning, control, and decision-making in an organization. An effective MIS focuses on products, customers, costs, marketing, and risks to make information available for strategic decision-making.
