Affinity mapping — an easy way to gather and analyse ideas as a team
Affinity mapping lets you solve problems, answer questions and make plans as a team. You generate a pool of ideas, spot patterns and then sum these up to guide your next steps.
What you need
- Post-its
- Sharpies
- Whiteboard
- Whiteboard markers
How it works
It’s a 6S process:
- State the goal
- Silent brainstorm
- Share out loud
- Sort
- Sum up
- Select your next step
State the goal
Start by letting people know what you want to achieve.
Silent brainstorm
Working separately, everyone writes down ideas for ways to achieve the goal, one idea per post-it. Any idea is a good one. You want to generate as many as possible.
Share out loud
Everyone takes turns to read out each of their ideas, clarifying as required. They stick these up on the whiteboard.
Sort the ideas
Then everyone comes up to the whiteboard and groups like with like. Put identical ideas on top of each other. Put similar ideas side by side. This creates clusters of related ideas. If different people see different groupings, discuss and agree as you go.
Sum up the clusters
Ask the team how they would summarise what each cluster covers and write the summary on the whiteboard. It's OK to have singletons.
Select your next step
You can now vote on the most important grouping and your next step.
We often use 3-2-1 voting. Everyone gets to vote for 3 choices, giving their top choice 3 votes (as ticks or tally marks beside that item on the whiteboard), their next highest 2 votes and their 3rd highest 1.
