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):

Management level

Inputs:High volume data

Processing:Simple models

Outputs:Summary reports

Users:Middle managers

Example: Annual budgeting





Structured and semi-structured decisions

Report control oriented

Past and present data

Internal orientation

Lengthy design process
