Diamond Ranking for Decision Making

Diamond Ranking for Decision Making


Purpose

When making decisions, you often need to choose between a series of options. When told to rank options, people sometimes want to give the same rank to multiple options. In some cases, it might be more important to learn about the most and least preferred options rather than to spend time judging between the middle choices.

A technique known as Diamond Ranking can help you focus on the most and least preferred options.

Objective

Use the Diamond Ranking technique to make decisions.

What You Need

  • Blank cards

Setup

  • Get the delegates to work on a given problem and generate options using a technique that is suitable for your training needs.
  • Ask the delegates to rank the options based on the pattern of a diamonds shown above (left pattern).
  • If there are the right number of options (say 9), this is straightforward. Otherwise, delegates may need to cluster options in a certain level more than others. This is fine. What matters most is what options end up at the two points and the decision process they go through to decide that.
  • If there are many options, you can expand the diamond to accommodate all options. In any case, keep only 5 main levels between the best and worst choices. This is because you want to minimise decision making on middle choices and instead focus on what ends up on extreme ends. For example, you can aim for the pattern shown on the right in the image above.
  • Allocate 15 minutes.
  • Follow with a discussion.
