To make the most of bringing people together to talk about deciding something, you need to decide between different good ways of bringing people together, don't try to make all the good ways work for everyone at once. It is better to let people end with different thoughts than pretend everyone agrees. You should write down what people thought at the end and make it clear how that is used in deciding something. Plan to share in open ways, so others can learn from what happened and what people thought at the end - others might use what you shared in ways you didn't plan, but that might help bringing people together mean more.
