Limitation of MIS MIS cannot replace managerial judgments in decision making.
it is an effective tool for the managers in decision making andproblem solving.
MIS is less useful for making non programmed decisions
MIS in organizations is less effective where information is not
being shared with others.
MIS may not have enough flexibility to update itself quickly, in afast changing and complex environment,
MIS cannot provide tailor made information packages. It is
required to analyze the available information before decisionmaking.
The quality of output of MIS is directly proportional to the qualityof input and processes.
MIS is less effective due to frequent changes in top management,organizational structure and operational staff. 17
