Efficiency oriented

21
Q

a knowledge-based system, used by senior managers, which facilitates the creation of knowledge and allows its integration into the organization.

22
Q

This system is often used to analyze existing structured information and allows managers to project the potential effects of their decisions into the future.

A

DSS

23
Q

It is usually interactive and is used to solve ill-structured problems.

A

DSS

24
Q

It offers access to databases, analytical tools, allows “what if” simulations, and may support the exchange of information within the organization.

A

DSS

25
Q

manipulates and builds upon the information from a MIS and/or TPS to generate insights and new information.

A

DSS

26
Q

Examples of DSS

A

Group Decision Support Systems (GDSS)
Computer Supported Co-operative work (CSCW)
Logistics systems
Financial Planning systems
Spreadsheet Models

27
Q
