✅ Why this step helps you find clarity in complexity
You’ve gathered loads of insights, feedback, or ideas—but it’s all a bit messy.
Affinity diagramming helps you organise scattered information into meaningful themes. It’s a powerful method to group observations and identify patterns, especially after interviews, research sessions, or idea generation. This step gives you a clearer picture of what matters—and what to do next.
📘 What you’ll make sense of
- User quotes, behaviours, or needs from interviews
- Brainstormed ideas, challenges, or features
- Observations from product testing or workshops
- Notes from team debriefs or planning sessions
- Themes that suggest product directions, pain points, or opportunities
🛠️ Tools and methods
✅ Step-by-step checklist
Prepare sticky notes or digital cards — one idea or quote per note
Work solo first: write freely without grouping
Move notes into a shared space (physical or digital)
Group similar notes together into rough clusters
Name each group with a short, behaviour-based label
Discuss gaps, overlaps, and unclear notes with your team
Capture final themes and next actions for framing or prioritisation
Example Theme Table
| Sticky Notes (Summarised) | Theme |
| Didn't know how to reset, manual unclear, support questions | Setup confusion |
| Feels solid, nice materials, looks premium | Perceived quality |
| Would use daily, fits into routine | Habit fit |
- Use tools like Miro, FigJam, or Notion boards to run remote sessions
- Document your final themes and feed them into your product planning
⚠️ Common pitfalls
- Jumping to conclusions too soon — let themes emerge naturally
- Over-labeling — keep group names simple and user-focused
- Excluding voices — include notes from all roles, not just designers
- Forgetting to share — summarise and save the outputs for later use
💡 From synthesis teams
“We thought we had ten ideas—but affinity sorting showed just three underlying problems. That clarity shaped our MVP and saved us months.”– Innovation Coach, CleanTech Accelerator
💡 Run this session as a team. Talking while sorting reveals as much as the notes themselves.

✍️ Quick self-check
Have we grouped the notes from all team members and sources?
Are our themes simple, relevant, and linked to user behaviour?
Did everyone contribute and understand the final clusters?
Have we saved the outputs in a way we can reuse?
