Plurality
A decision method where the choice with the largest share of support prevails, even if it does not receive more than half of all votes.
Key Points
- The winning option is the one with the most votes, not necessarily more than 50%.
- Different from majority (over 50%) and unanimity (100% agreement).
- Useful when there are many alternatives and a quick decision is needed.
- May require follow-up actions to build broader buy-in and define tie-breakers.
Example
A project team must select one of four vendors. In a vote of 12 members, Vendor A gets 5 votes, Vendor B gets 4, Vendor C gets 2, and Vendor D gets 1. Vendor A is selected because it has the largest number of votes, even though it does not have a majority.
