Consensus is a process for group decision-making. It is a method by which an entire group of people can come to an agreement. The input and ideas of all participants are gathered and synthesized to arrive at a final decision acceptable to all. Through consensus, we are not only working to achieve better solutions, but also to promote the growth of community and trust.
Voting is a means by which we choose one alternative from several. Consensus, on the other hand, is a process of synthesizing many diverse elements together.
Voting is a win or lose model, in which people are more often concerned with the numbers it takes to "win" than with the issue itself. Voting does not take into account individual feelings or needs. In essence, it is a quantitative, rather than qualitative, method of decision-making.
With consensus people can and should work through differences and reach a mutually satisfactory position. It is possible for one person's insights or strongly held beliefs to sway the whole group. No ideas are lost, each member's input is valued as part of the solution.
A group committed to consensus may utilize other forms of decision making (individual, compromise, majority rules) when appropriate; however, a group that has adopted a consensus model will use that process for any item that brings up a lot of emotions, is something that concerns people's ethics, politics, morals or other areas where there is much investment.
