(MIS) A computer system, usually based on a mainframe or minicomputer, designed to provide management personnel with up-to-date information on an organisation's performance, e.g. inventory and sales. These systems output information in a form that is useable by managers at all levels of the organisation: strategic, tactical, and operational. A good example of an MIS report is an annual report for a stockholder (a scheduled report).
