Term
| What is the difference between problem solving and decision making? |
|
Definition
| The decision making phase is only intelligence, design and choice where problem solving includes and goes beyond decision making.: |

Decision Support System
A organised collection of people, procedures, software, databases and devices that are in place to support managerial decision making and problem solving activities |
|
|
Term
|
Definition
| DSSs are used to bring structure to the unstructured problems that are found within a organisation. |
|
|
Term
| What are the main components of a DSS? |
|
Definition
| A database, model base, dialogue manager and links to external sources such as internet, corporate intranet and other external databases. |
|
|
Term
| What are the 4 capabilities of a DSS? |
|
Definition
- Support for problem solving phases
- Support for different decision frequencies
- Support for different problem structures
- Support for various decision-making levels |
|
|
Term
| Compare a DSSs to a MISs briefly |
|
Definition
- A DSS is usually used to support unstructured problems and a MIS usually deals with structured problems.
- A DSS supports individuals, small groups and the entire organisation and a MIS supports primarily the organisation
- A DSS supports all aspects and phases of decision making but doesn't replace the decision maker (people still make decisions) where as some MISs make the decisions and replace the decision maker |
