Management information system
MIS makes information available to relevant users by producing pre-determined and pre-designed reports required by the management.
Management information system helps middle level management planning, controlling and decision making. The data stored can be used or manipulated to produce differently defined reports from pre-defined reports. It can be presented graphically or pictorially. The reports generated by the MIS are used for analytical decision making by the management. The application software can construct projections, build scenarios, do what if analysis to enable better Decision making.
- MIS
- Provides information on monitoring and controlling the business
- Fixed and regular reports are generated from data kept in TPS.
- Report formats are predefined.
- User is part of the system
- Controlled by IT Dept
Decision Support Systems
DSS was defined by Bill Inmon, father of data warehouse, as "a system used to support managerial decisions. Usually DSS involves the analysis of many units of data in a heuristic fashion. As a rule, DSS processing does not involve the update of data"
- DSS
- Helps in non routine decision making
- Users are not linked with the structured information flows.
- Greater emphasis on models, display graphics & ad hoc queries
- DSS is a small part of users' actions.
- Directly used by middle level managers
