GDSS vs DSS: Difference and Comparison

Thinking about decisions and making them according to the situation is essential to life. They are extremely important in business and can spell the difference between profit and loss.

Of course, decision-making should be left to those with analytical brains, but it never hurts to have the correct equipment to assist the writer.

The GDSS (Group Software Application) and DSS (Decision Support System) enter the picture at this point.

Key Takeaways

  1. GDSS stands for Group Decision Support System, which is a system designed to help groups make decisions together. In contrast, DSS stands for Decision Support System, which is a system designed to help individuals make decisions.
  2. GDSS includes features like brainstorming, discussion forums, and voting, while DSS includes data analysis and modelling.
  3. GDSS is more useful for group decision-making processes, while DSS is more useful for individual decision-making processes.

GDSS vs DSS 

The difference between GDSS and DSS is based on the participation of human beings in the process of developing a decision. The DSS is an important tool that assists a person in weighing various considerations and making the best decision possible. GDSS, on the other hand, assists a group of people in brainstorming ideas and determining the best course of action. 

GDSS vs DSS

The full form of GDSS is a group decision-support system. GDSS is a system that is interactive and based on a computer.

It helps a group of decision-makers solve unstructured situations (DeSanctis and Gallupe, 1987). It provides tools and technologies that are specifically designed for group decision-making. 

A decision support system (DSS) is a software application that aids in making decisions, judgments, or actions to be taken in a business or firm.

A data science platform sifts through it and evaluates large amounts of data, generating complete data that can be used to solve problems and make decisions. 

Comparison Table

Parameters of Comparison GDSS DSS 
Involvement of people The GDSS is associated with the group. The DSS is associated with a person. 
Fundamental The GDSS is based on ideas and uses them as a method too. The DSS is based on knowledge and mathematical formulas. 
Requirement A working network is required in GDSS. No Working network is needed in DSS. 
 Application It is seen that GDSS decisions are mostly suitable for every case. It is seen that DSS decisions are not suitable for most cases.  
Judgement Parameters  The decision is discussed in the group and all the ideas are welcomed. Formulas and knowledge are used for confirmation purposes so past experiments are the judge of decision.

Even though the collaboration, including Internet teleconference and online meeting solutions mentioned earlier in this article, can help with some group decision-making, their primary focus is on communication.

GDSS was formed in response to a growing concern about meeting quality and efficacy and delivers methods and software specially tailored for group decision-making.

One of the fundamental issues in a joint decision has been the explosion of decision-making.

Three to five attendees are the best meeting size for decision-making meetings without GDSS support. As the group grows larger, the meeting process begins to break down.

According to studies, adopting GDSS software can increase the number of attendees at a meeting while also increasing efficiency.

One reason for this is that attendees contribute at the same time rather than one at a time, allowing for more efficient use of meeting time.

What is DSS? 

A decision support system (DSS) is a software application that aids in making decisions, judgments, or actions to be taken in a business or firm.

A data science platform sifts through it and evaluates large amounts of data, generating complete data that can be used to solve problems and make decisions. 

A DSS’s typical data contains an objective or expected revenue, sales figures or historical data from various periods, and other inventory and operations-related data.

A DSS could be used to estimate revenue for another six months based on new product revenue goals. 

A traditional application gathers and processes information before integrating it into complete reports. In this regard, a DSS differs from standard operations software in that it collects data rather than provides information.

The DSS might be entirely automated or run entirely by people. It may incorporate both in some instances.

The ideal systems assess data and make decisions on behalf of the user. At the very least, they allow humans to make more informed decisions in a shorter amount of time. 

 Main Differences Between GDSS and DSS 

  1. The distinction between GDSS and DSS is the number of people who are participating in the procedure and development of the decision-making process. The DSS is a helping tool that aids a person in weighing many factors and arriving at the best possible option. GDSS, on the other hand, helps and supports a group of people to come up with new and creative ideas and decide over determine on the best course for the path of action. 
  2. The GDSS is based on ideas and discussion of the people, thus, is used as a method, whereas The DSS is based on knowledge and mathematical formulas. 
  3. A working network is required in GDSS, whereas No Working network is needed in DSS. 
  4. It is seen that GDSS decisions are mostly suitable for every case, whereas it is seen that DSS decisions are not suitable for most cases. 
  5. The decision is discussed in the group, and all the ideas are welcomed, whereas Formulas and knowledge are used for the confirmation purpose so past experiments are the judge of the decision.
