Management Information System (MIS)

Management Information System (MIS)

An MIS provides managers with information and support for effective decision making, and provides feedback on daily operations.

MIS provides information to the users in the form of reports

Output, or reports, are usually generated through accumulation of transaction processing data.

MIS is an integrated collection of subsystems, which are typically organized along functional lines within an organization.

Management Information System (MIS):
