Affinity Grouping

What is Affinity Grouping?

Affinity grouping can be used as a collaborative prioritization activity. It works by having your group of participants brainstorm ideas and opportunities on Post-It Notes. The team then works to put the sticky notes into groups of similar items. Once the groups are created, the team votes on the groups to rank them.

Affinity grouping is a collaborative prioritization and brainstorming technique with many different possible applications. This article will provide a broad overview of the process as well as some tips for product managers who want to use affinity grouping to prioritize their product roadmap.

The general idea behind this method is simple. Participants get together and brainstorm several ideas and opportunities. Then, the group works together to sort their new ideas into thematic clusters. After establishing several “affinity groups” of initiatives, the group can vote and rank each group. At the end of the activity, you’ll have a prioritized list of new ideas.Affinity Grouping Activity Example

How Do You Facilitate an Affinity Grouping Activity?

Affinity grouping does not need to be an extremely formal or complicated activity. Here’s how to facilitate a very basic session.

  1. Get a group of participants together. Ideally, participants from various parts within the organization can participate so you get a wide variety of ideas and perspectives.
  2. As a group, write down as many ideas as possible. You can use Post-It notes, note cards, a whiteboard, or even a piece of paper.
  3. Work with participants to sort through your ideas and group similar ideas into “affinity groups.” These help keep ideas organized by themes.
  4. As a group, vote on different themes. You can treat this like a buy-a-feature prioritization session, or simply have everyone work as a group to rank the themes by importance.

When Should You Use Affinity Grouping?

Affinity grouping activities are useful for product teams in need of ways to collaboratively brainstorm new projects and features. These activities are great opportunities to bring together members from various functional departments. In addition, they allow other teams (i.e. marketing, sales, etc.) to actively participate in product roadmapping and have a say in the product.
