What is a Group Decision Room

The Group Decision Room is an inspirational environment where sensitive subjects and important topics can be discussed without dominance and hierarchy. The wisdom of the crowd will provide insights, and decisions will be made. We accomplish this by implementing the GDSS in our Group Decision Room. The Spilter GDSS (Group Decision Support System) has been developed in-house and is one of the leading systems worldwide. The Group Decision Room is also known by the acronym GDR.

The Group Decision Room is comprised of three key parts: the process facilitator, the software and the participants. An experienced consultant knows like no other how to leverage the software in the most effective manner. If desired, we can also assist with asking the appropriate questions and selecting relevant forms of questions and analysis. This provides the capability to expose differences of opinion right away so that participants can discuss the issues that truly matter and so that you can obtain maximum benefits from the knowledge of all participants.

Digital and analogue activities complement each other in a Group Decision Room. The software visualises differences of opinion in real-time so that participants can focus on the content that truly matters. The input collected can be presented easily to gauge the group’s opinions. The results are available in a report at the end of the session, so that less time is necessary for processing the details.

We truly believe Spilter provide us with added value for the discussion and the subsequent yield

 Refreshing and new: the working method and approach left us feeling something had really been done with our input.

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

Group Decision Room with Spilter


All participants in a Group Decision Room use a device, such as a smartphone, tablet or laptop. They can use their own devices or you can have us provide them. We will build the Group Decision Room for you with laptops or iPads and then we will take everything with us after your meeting has finished. The Group Decision Room software is web-based; therefore, all you need is Wifi or one of our local servers and a power socket.

Our professional and experienced facilitators are also happy to advise you. They give their input and lead the group process in a methodical and decisive manner so that you can be certain your objective will be achieved. Of course, you also have the option to just use the platform in your own Group Decision Room with technical support. During your session, an experienced operator will operate the software so that the process facilitator can fully focus on the group and the discussion. We offer various levels of support to meet your needs and requirements.
