SUPPORT SYSTEMS
Learning Objectives
Understand concepts and fundamentals of groupwork,
communications, and collaboration.
Examine how computer systems enhance communication and
collaboration.
Understand the principles and capabilities of GSS.

and loss, and task gain and loss.
Understand the fundamentals of electronic meetings.
Examine GSS’ three technologies.
Learn how the Web enables GSS, electronic meetings, and
collaborative computing.
Explain hoe distance learning is enabled by GSS.
Show how GSS enhances creativity.
Collaborative Design at Boeing-Rocketdyne
Problem
Drive the cost of rocket engine down 95%
Get the engine to market 10 time faster
Require radical new design, significant creativity, and unusual
innovation
Solution
Created expert team from business partner
Used collaborative technology
Internal
Notebook : Members could access the software securely
from anywhere. Could create, comment on, reference-link, search,
and short-entries also use electronic whiteboard that allowed
multiple team members near-instance access.

Collaborative Design at Boeing-Rocketdyne
Solution
Project Vault : A software allowed secured common file
storage and transfer of these files on as-needed basis.
Software tools and protocol were modified and allowed
which allowed face-to-face meeting, content was posted
online for group sharing.
Major tools used to support the lengthy virtual meetings by
teleconferencing and videoconferencing.
Used powerful desktop analysis software to analyse
designs during the meeting, so results could be discussed in
real-time and evaluted through brainstorming.
Collaborative Design at Boeing-Rocketdyne
Result
Designed
a product made of 6 parts instead of normal
1200
Cost $0.5 million from $14 million
Quality level 9 sigma from 2-6 sigma
Team did all this in 10 months instead of 6 years
Production cost $47,000 instead of $4.5 million and with
more than a 5 percent reduction in total engineering
hours.
Making decisions in Groups :
Characteristics
Groupwork
Work done by two or more people together.
Members can be located in different places and work
at different times
Information may be located external to the project
Allows for rapid solutions
May exhibit normal team problems of synergy or
conflict
Often Internet based
Groupware tools support groupwork
Work called computer-supported cooperative work
Group Decision-Making Process
Even in hierarchical organizations, decision making is
usually a shared process. The following activities and
process characterize meetings:
The
decision situation is important, so it is advisable to
make it in a group in a meeting
Joint activity
Outcome of the meeting depends partly on the knowledge,
opinions, judgement and composition of its participants.
Differences in opinion are settled either by the ranking
person, or through negotiation or arbitration.
They can be virtual team
May be beneficial or dissatisfaction
Benefits and limitation of group work
Process gains are the benefit of working in group
It provides learning. Groups are better than individuals at
understanding problems
People readily take ownership and responsibility
Group members have their egos embedded in the decision
Groups are better than individuals at catching errors
A group has more information
A group may produce synergy
Working in group may stimulate the creativity
A group may have better and more precise communication working
together
Risk propensity is balanced
Benefits and limitation of group work
Dysfunction may occur Process loss
Social pressure of conformity may result in groupthink
It’s a time consuming, slow process, costly
There can be lack of coordination of the meeting and poor meeting
planning
Inappropriate influence
Some members may afraid to speak up
Can be compromised solutions of poor quality
Too much information
Incomplete, incorrect and inappropriate
Improving the meeting Process
Researchers have developed methods for
improving the process of group work; that is,
increasing some of the benefits of meeting and
eliminating of reducing some of the losses. Two
representative methods
Delphi method : is a qualitative forecasting methodology that
uses anonymous questionnaires.
Nominal group thinking : is a simple brainstorming process for
non-electronic meeting.

Supporting group-work with computerized
systems
Almost all dynamic organizations using some computerbased communication and collaboration methods and
tools to support people working in teams or group.

Increase effectiveness of decisions
Computers have been used for several decades to
facilitate group-work and group decision making, lately,
collaborative tools have received even greater attention
due to their increased capabilities and ability to save
money.
Groupware
Software providing collaborative support to groups
Different time/place applications
Most use Internet technologies
Most offer one or more capabilities
Electronic brainstorming
Free flow of ideas and comments
Electronic conferencing or videoconferencing
Group scheduling and calendars
Conflict resolution
Model building
Electronic document sharing
Voting services
Electronic meeting services also available
Enterprise-wide systems expensive in cost and human resources
Popular Groupware
Groupware products provides a way for group to
share resources and opinions. Groupware implies
the use of networks to connect people.

GSS Meeting Process
Group leader meets with facilitator to plan meeting
structure.
Participants meet on computers.
Group leader or facilitator poses question.
Participants brainstorm by entering comments into
computer.
Facilitator employs idea organization software to sort
comments into common themes.
Results are displayed.
Facilitator or group leader leads discussion.
Themes are prioritized.
Highest priority topics are either sent through the process
again for further discussion or a vote is taken.
