In any good brainstorming session, there will come a time when there are too many good ideas, too many concepts, and too many possibilities to proceed. When this time has come, dot voting is one of the simplest ways to prioritize and converge upon an agreed solution.
At least 3 participants; in larger groups, tallying votes will be more time-consuming
First, the group needs a set of things to vote on! This may be something they have just developed, such as a wall of sticky notes, or it may be a flip-chart list that captures the ideas in one place. Ask the group to cast their votes by placing a dot next to the items they feel the most strongly about. They may use stickers or markers to do this. As a rule of thumb, giving each participant five votes to cast works well.
Participants cast their votes all at once and they may vote more than once for a single item if they feel strongly about it. Once all the votes are cast, tally them, and if necessary make a list of the items by their new rank.
This prioritized list becomes the subject of discussion and decision making. In some cases, it may be useful to reflect on ideas that didn't receive votes to verify that they haven't been left behind without cause.
This technique is used to collaboratively prioritize any set of items. It could be used to hone a list of features, to agree on discussion topics, or to choose among strategies and concepts. Giving participants five votes is enough to be meaningful while still asking for individual prioritization; however, this is not a hard rule.
