Nominal group technique (or NGT) is a way to make sure everyone in a group gets the chance to share their ideas. It's used when a group of people are trying to make a decision together or solve a problem.
The way it works is that everyone sits together in a circle, or online in a group chat, and they take turns saying ideas out loud. The leader then writes or types down all the different ideas and makes sure everyone is heard before they continue. Once the ideas are written down, the group can then compare the ideas and decide which one to use.
Using the NGT technique helps everyone in the group to make sure their ideas are heard and can help groups come up with the best possible answer for the problem.
