Two Heads are Better than One!

6 Mar

While the DSS I have discussed so far focuses largely on individual decision making-important at administrative and managerial level- I am aware that in today’s business world much work is accomplished in groups within organizations. This is where Group Decision Support Systems or GDSS comes in! “A Group Decision Support System is an interactive, computer-based system that facilitates solutions to unstructured problems by a set of decision makers working together as a group” (DeSanctis and Gallupe,1987)

GDSS are being used more widely so we can evaluate some of their benefits and tools.

The benefits, or process gains, from using a GDSS (over more traditional group techniques) are:

  • More precise communication;
  • Synergy: members are empowered to build on ideas of others;
  • More objective evaluation of ideas;
  • Stimulation of individuals to increase participation;
  • Learning: group members imitate and learn from successful behaviors of others.

The costs, or process losses, from using a GDSS (instead of more traditional group techniques) are:

  • More free riding;
  • More information overload;
  • More flaming;
  • Slower feedback;
  • Fewer information cues;
  • Incomplete use of information.

However, researchers have found that GDSS over traditional group techniques limited or reduced the following process losses:

  • Less attention blocking
  • Less conformance pressure
  • Less airtime fragmentation
  • Less attenuation blocking
  • Less socializing
  • Less individual domination


Electronic GDSS has developed significantly since the 1980s, helping organizations like NASA, Intel, IBM and P&G to build better company communication networks and make decisions that enhance company services and growth. Advances in electronic infrastructure, processing, meeting space, and communication are just a few examples of how GDSS can improve organizational decision-making processes.

GDSS facilitates group decision making, which increases participation within an organisation and encourages innovation.


So there you go folks, I have written my sixth and final blog. I hope you have enjoyed reading these blogs and have learnt something from them. On behalf of all group 4: 110377583, 110722651, 111006439 and I, we would like to say we have enjoyed working on-line as a team on this on-line collaborative environment. We have benefited from the research we undertook into how IS helps organisations make decisions, and from reading all the other blogs and posts we have expanded our systems analysis and design knowledge. So until next time, over and out!

    Great blog ! I personally love GDSS 🙂 Could you give some examples, please? Thank you.

      Glad you enjoyed the blog 🙂 Examples of GDSS include Computer Supported Cooperative Work or CSCW. This software is less about technology and more about people as it is socially dependent; it looks at the way people interact and collaborate with each other andattempts to develop guidelines for developing technology toassist in the communication process. Examples of firms that use GDSS include IBM as stated above, it improved their group meeting. 🙂

    Great blog 😀 it was very descriptive, I am sorry to see that it is your last blog 😦 I like the way you brought businesses like NASA, INTEL and other big companies into the blog to make it clear for us to see how much GDSS has helped them when it comes to communicating and helping their business be more efficient and effective 😀 Thanks again 😀
