Advantages & Disadvantages

Components of GDSS

GDSS Alternatives

Future of GDSS

GDSS PRESENTATION TOPICS



Group Decision Support Systems (GDSS) - Aninteractive, computer-based system that facilitates

solution of unstructured problems by a set of decision-makers working together as a group. It aids groups,especially groups of managers, in analyzing problemsituations and in performing group decision making

tasks.

.

DEFINITIONS



Both use models, data and user-friendly software

Both are interactive with “what-if ” capabilities

Both use internal and external data

Both allow the decision maker to take an active

role

Both have flexible systems

Both have graphical output

SIMILARITIES BETWEEN

GDSS AND DSS



1. more information in less time2. Greater participatin

3. More structured

4. Automated documentation

WHY USE GDSS?



Special Design

Ease of use

CHARACTERISTICS OF GDSS



Specific and general support

Suppressing negative group behavior

Supporting positive group behavior

CONTD.



GDSS TIME/PLACE ENVIRONMENT

Same-Time

Same-Place

(Most widely used GDSS-computers with projectors, voting

tools)

Same-Time

Different-Place(team room, tools, audio

conferencing, screen sharing, chat)

Different-Time

Same-Place(audio/video conferencing,

document sharing)

Different-TimeDifferent-Place

(voice mail, email, bulletin boards)



Anonymity – drive out fear leading to betterdecisions from a diverse hierarchy of decision makers

Parallel Communication – eliminate monopolizing providing increased participation, better decisions

Automated record keeping – no need to take notes,

they’re automatically recorded

ADVANTAGES OF GDSS



Ability for virtual meetings – only need hardware,software and people connected

Portability - Can be set up to be portable… laptop

Global Potential - People can be connected across

the world

No need for a computer guru – although somebasic experience is a must

CONTD.



Cost – infrastructure costs to provide the hardwareand software/room/network connectivity can be

very expensive

Security – especially true when companies rent thefacilities for GDSS; also, the facilitator may be a

lower-level employee who may leak information topeers

Technical Failure – power loss, loss of connectivity,relies heavily on bandwidth and LAN/WANinfrastructure – properly setup system should

minimize this risk

DISADVANTAGES OF GDSS



Keyboarding Skills – reduced participation may result due tofrustration

Training – learning curve is present for users, varies by situation

Perception of messages – lack of verbal communication could

lead to misinterpretation

CONTD.



COMPONENTS OF A GDSS AND GDSS SOFTWARE

Database

Model base

Dialogue managerCommunication capability

Special software (also called GroupWare)

E.g., Lotus Notespeople located around the world work on

the same project, documents, and files,

efficiently and at the same time



GDSS ALTERNATIVES

Local area

decision network

Wide area

decision network

Decision

roomTeleconferencing

Location of group members

close distant

high

low

D e c i s i o n f r e q u

e n c y



WIDE AREA DECISION NETWORK

Characteristics

Location of group members is distant

Decision frequency is high

Virtual workgroups

Groups of workers located around the world working on common problems via a GDSS



DECISION ROOM

Decision Room

For decision makers located in the same geographic area

or building Use of computing devices, special software, networking

capabilities, display equipment, and a session leader

Collect, coordinate, and feed back organized information

to help a group make a decision

Combines face-to-face verbal interaction withtechnology-aided formalization





1) Group Leader (and Facilitator?) select software,develop agenda

2) Participants meet (in decision room/Internet) and aregiven a task.

3) Participants generate ideas – brainstorm anonymously4) Facilitator organize ideas into categories (different for

user-driven software)

5) Discussion and prioritization – may involve ranking bysome criteria and/or rating to the facilitators scale

6) Repeat Steps 3, 4, 5 as necessary

7) Reach decision

8) Recommend providing feedback on decision andresults to all involved

TYPICAL GDSS PROCESS



Integrating into existing corporate framework

GDSS brings changes which must be managed

GDSS will incorporate Artificial Intelligence and Expert

Systems – the software will “learn” and help the usersmake better decisions

Decreasing cost will allow more organizations to use

GDSS

Increasing implementation of GDSS with the customer

Customer voice their needs in non-threatening

environment

FUTURE IMPLICATIONS OF GDSS



GDSS may play a large role in the future of the virtual

companies

GDSS can help the virtual companies do business in the

global business environment

GDSS can help promote a culturally diverse work

environment

Telework seems to make a lot of sense using GDSS

FUTURE IMPLICATIONS OF GDSS
