Final answer:
The nominal group technique is the selection tool that quickly reduces a list of items to a few choices by engaging all group members in ranking the options.
Step-by-step explanation:
The selection tool used to quickly reduce a list of items to two or three choices from the options given is the nominal group technique. A decision tree is useful for making complex decisions with different outcomes, while a Pareto chart is generally used to prioritize issues by identifying the most significant factors and sorting bars from largest to smallest. A fishbone diagram is typically utilized for identifying many possible causes for a problem and organizing them. Therefore, the nominal group technique, which involves all members of the group in the decision-making process and ranks the options, is best suited for narrowing down a list of choices to a manageable number.
The selection tool used to quickly reduce a list of items to two or three choices is the Decision tree. A decision tree is a graphical representation of decisions and their possible consequences, which helps in systematically analyzing and evaluating different options. It allows individuals to weigh the pros and cons of each choice, leading to a final decision.
