The document provides an overview of management information systems (MIS) and how they have evolved over time. Early systems involved manually collecting and reporting limited data on business performance periodically. Over time, businesses began storing larger amounts of detailed data and linking separate information systems to provide managers with reports. The term "MIS" was developed to describe applications that collected, processed, stored and disseminated management data. MIS systems have advanced from manual typewriters to touchscreen computers, manual filing to computerized storage, floppy disks to external hard drives, providing faster, easier, more accurate and secure data gathering, collection and storage.
