What is a GDSS

A GDSS (Group Decision Support System) is software that digitally supports creative and decision-making processes. A well-known application for this is the Group Decision Room. Since all participants provide input at the same time, you have immediate insight into areas of agreement and differences of opinion. This allows the group to discuss truly important matters. Scientific studies show that GDSS decision-making processes not only progress faster, the quality of the results is also higher.

Spilter GDSS is the most comprehensive GDSS software available. It supports every topic, regardless of the complexity, no matter the method. Participants are more involved in the entire process, whereby the outcomes of the meeting are widely supported. It gathers and uses the knowledge and opinions of all participants. Since there is more insight into what others are thinking, there is more contact and interaction among everyone present.

You have to experience it for yourself to see how effective it is.
