Which QDM tool aids a group in reaching a consensus?

Multivoting is a decision-making tool that helps a group reach consensus by allowing participants to rank or vote on options or ideas. This process condenses a large number of choices into a more manageable number, helping the group to identify the most favored options through systematic elimination. By enabling individuals to express their preferences and collectively seeing the group's choices, multivoting helps facilitate discussion and can lead to a clear consensus on the next steps or the most important issues.

The other tools serve different purposes. Affinity grouping is designed to categorize ideas into clusters based on their natural relationships, which can be useful for organizing thoughts but does not directly lead to a decision-making process. Flowcharting is a visual tool primarily used to map out processes or workflows, helping understand sequences and relationships rather than aiding in reaching a consensus. The fishbone diagram, also known as a cause-and-effect diagram, is typically used for identifying the root causes of problems, which is more analytical than consensus-building. Each of these tools plays an important role in quality management practices but targets different aspects of team collaboration and problem-solving.
