It's pretty common that in any given group, the subset of people who have good ideas and the subset of people who are comfortable dominating a group conversation are not entirely the same.<p>One strategy that I've found is sometimes helpful that recognizes this fact is to start group decision making by having everyone write ideas down independently on sticky notes for, say, 5 minutes. This means every person present ends up with a physical representation of the fact that they have ideas, sitting in front of them on the table.<p>Then, in a second phase, you can put them on a board and organize them, evaluate them, vote on them, etc. Since the ideas are now sticky notes on a board, they can be evaluated (more) independently of the person who articulated them.<p>The first time I participated in something like this, it felt like Kindergarten, and I didn't really appreciate it. But after some practice, I've come to appreciate that it gives every member of a group the chance to contribute ideas, without having to simultaneously finesse the holding-the-floor game.
