Weighted voting is most useful for 'taking the temperature of a group' as it works towards consensus. It is also sometimes used to reduce the number of ideas or select one from a list. Because weighted voting is based on the positions and preferences of group members and involves neither selection criteria nor discussion, it seldom produces a satisfactory agreement by itself.

How to Use Weighted Voting

Draw a table — options by members — on a flip chart, as shown below. Give each member a number of votes to distribute in line with their preferences. As a rule of thumb, the number of votes should be about 1½ times the number of options. Members then decide how to distribute their votes among the options to indicate their relative preferences.

The following is an example of weighted voting used by a team trying to agree on where to have their Christmas lunch. Each member had six votes to distribute among four options.

Weighted voting does not make decisions. It merely gives the group information on where the individual members stand — and how strongly. This information makes it easier to uncover opposing viewpoints. Consensus cannot be reached without dealing with those viewpoints.

Variation

Instead of giving people a number of votes of equal value to be distributed as they like, you could provide them with a set of 'pre-weighted' votes to help separate the options. In the above example, you could give people three votes with values of 1, 3 and 5 to distribute among the four options. I'm unsure if this is a good recommendation, but this system is used in the "Eurovision Song Contest".
