Opening Vignette: Chrysler SCORES with Groupware
Chrysler used groupware to enhance collaboration and communication with suppliers
Identify waste in the Value Chain Eliminate the waste

Meetings
Joint activity Equal or near equal status Outcome depends on participant’s knowledge,
etc. Outcome depends on group composition Outcome depends on decision-making process Disagreement settled by rank or negotiation

Groupware
To support groupwork / meetings … Computer-supported cooperative work
(CSCW) Software that provides collaborative
support to groups

Group Support Systems
Goal: to support groupwork Increase benefits / decrease losses of
collaboration Based on
Nominal Group Technique Delphi Method
Electronic Meeting System (EMS)
![Page 19: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/19.jpg)

Important Features
Parallelism Anonymity
Lead to process gains and task gains
![Page 20: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/20.jpg)

GSS Process Gains
Parallel information processing / flow Larger groups can participate Rapid computer discussions Quiet people can participate equally Noisy people can’t strongly drive meeting Saves travel time (millions $ / year)

Few OrganizationsUse Decision Rooms
High Cost Need for a Trained Facilitator Software Support for Cooperative Tasks,
NOT Conflict Issues Infrequent Use Different Place / Different Time Needs May Need More Than One

Multiple Use Facility Cheaper Still need a facilitator
Web-based Cheaper: no extra hardware needed Still need facilitator

GSS Meeting Process
Idea generation Idea organization Prioritizing Idea generation
Iterate until solution is reached
![Page 32: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/32.jpg)

Why GSS?
Successful Need
Organizational commitment Executive sponsor Operating sponsor User-seductive interface Dedicated well-trained facilitator Good planning
![Page 33: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/33.jpg)

Distance Learning (DL)
Nontraditional classroom CSCW / GSS / Groupware Requires technology Not new Effective Growing fast Corporate, too
![Page 34: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/34.jpg)
34
DL Advantages Just as effective or more Flexible time Student can keep job Student can travel in job Access anywhere / anytime Can present new technology cheaply Can focus on specific skills Can cost less Expand classroom size easily
![Page 35: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/35.jpg)
35
More DL Advantages
Add breadth and depth to course More one-on-one interaction with instructor
(e-mail) Student/faculty contact time increases For continuous learners Attendance is flexible (Careful!) Discussion technologies Student attitudes evolve and improve Impacts (scores) are higher
![Page 36: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/36.jpg)
36
DL Disadvantages
Fewer social interactions Less or no on-campus interaction Communications problems Students MUST be highly motivated Students MUST be highly disciplined Students MUST have effective time
management skills Students MUST be extremely dedicated
![Page 37: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/37.jpg)
37
More DL Disadvantages
Takes more faculty and staff time Learner must be more responsible Students MUST work hard!

Creativity and Idea Generation
Creativity: Generally a human trait Creativity and innovation
Can create tremendous impacts in organizations
![Page 40: 1 SEGMENT 5 Collaborative Computing Technologies: Group Support Systems.](https://reader030.fdocuments.net/reader030/viewer/2022032803/56649e375503460f94b27e58/html5/thumbnails/40.jpg)
40
Idea Generation Electronic Brainstorming Can be simulated Can adjust methods
Create more ideas (information overload)
Cognitive maps - useful

Creativity
Software that exhibits creativity
Intelligent agents (softbots) Copycat (creates analogies) AARON (creates painted art) Genjam (writes jazz music) Kurzweil’s Cybernetic Poet (writes poems)
