Definition

A group decision support system is an interactive, computer-based system that

facilitates group decision making by providing tools to facilitate communication,

encourage brainstorming, and manage shared information.

A Group Decision Support System (GDSS), also known as an Electronic Meeting

System or groupware, is commonly defined as a collection of software, hardware,

and procedures designed for the automated support of group work.

A GDSS aims to improve the process of group decision making by removing

common communication barriers, providing techniques for structuring decision

analysis, and systematically directing the pattern, timing, or content of discussion

Components of GDSS

The components of a GDSSare basically similar to those ofDSS, including

hardware, software, and people; but in addition, within the collaborative environment,

communication and networking technologies are added for group participation from

different sites.

There are three fundamental types of components that compose GDSS

1. Software

The software part may consist of the following components: databases and database

management capabilities, user/system interface with multi-user access, specific

applications to facilitate group decision-makers activities, and modeling capabilities.

2. Hardware

The hardware part may consist of the following components: I/O devices, PCs or

workstations, individual monitors for each participant or a public screen for group,

and a network to link participants to each other.

3. People

The people may include decision-making participants and /or facilitator. A facilitator

is a person who directs the group through the planning process.
