Management Support Systems:

Presented by:Nitin Kr. Banka

Management Support Systems 

The support of management tasks by the application of technologies 

Sometimes called Decision Support Systems or Business Intelligence

Learning Objectives 

  



Understand how management uses computer technologies. Learn basic concepts of decision-making. Understands decision support systems. Recognize different types of decision support systems used in the workplace. Determine which type of decision support system is applicable in specific situations.

Factors Affecting DecisionMaking  





New technologies and better information distribution have resulted in more alternatives for management. Complex operations have increased the costs of errors, causing a chain reaction throughout the organization. Rapidly changing global economies and markets are producing greater uncertainty and requiring faster response in order to maintain competitive advantages. Increasing governmental regulation coupled with political destabilization have caused great uncertainty.

What do Management Support Systems Offer?    



 

Quick computations at a lower cost Group collaboration and communication Increased productivity Ready access to information stored in multiple databases and data warehouse Ability to analyze multiple alternatives and apply risk management Enterprise resource management Tools to obtain and maintain competitive advantage

Cognitive Limits 









The human mind has limited processing and storage capabilities. Any single person is therefore limited in their decision making abilities. Collaboration with others allows for a wider range of possible answers, but will often be faced with communications problems. Computers improve the coordination of these activities. This knowledge sharing is enhanced through the use of GSS, KMS, and EIS

Six Major Types Of Systems 





TPS - Computerized system that perform and record the daily routine transaction necessary to conduct the business. OS - Computer systems, such as word processing ,e-mail, scheduling, that are designed to increase the productivity of data workers in office. KWS - Information system that aid knowledge workers in the creation and integration of new knowledge in the organization.







MIS - Information systems at management level to serve the function of planning, controlling, and decision making by providing routine summary and expectation reports. DSS - Information systems at management level to combine data and sophisticated analysis model to support non routine decision making. ESS - Information systems at strategic level designed to address non routine decision making through advanced graphics and communication
