What is an affinity diagram?

An affinity diagram is a visual tool used to organize large amounts of information into meaningful groups based on relationships and themes. It helps you make sense of complex data, identify patterns, and extract key insights – whether from user research, brainstorming sessions, or business planning.

Originally developed in the 1960s by Japanese anthropologist Jiro Kawakita, this technique was first known as the ‘KJ Method’. Kawakita used it to analyze ethnographic data, realizing that spatially grouping information revealed meaningful connections. Over time, this method gained popularity across industries and became a key tool in design thinking, UX research, and problem-solving frameworks.

At its core, an affinity diagram is about turning chaos into clarity. When dealing with large volumes of qualitative data – like interview transcripts, survey responses, or brainstorming ideas – it helps you sort and categorize information into logical clusters. This makes it easier to identify recurring themes, prioritize key findings, and drive informed decision-making.

While affinity diagrams were traditionally created with sticky notes on a wall (and this still has its place!), digital tools have made them even more accessible – allowing remote teams to collaborate effortlessly.

Examples of affinity diagrams

Affinity diagrams are used across industries to organize data, uncover patterns, and streamline decision-making. Here are some real-world examples of how they’re applied:

  • UX research data categorization: After conducting usability testing on a new onboarding flow, a UX team uses an affinity diagram to group feedback into themes like "confusing navigation," "missing instructions," and "positive first impressions."

  • Brainstorming and idea clustering: During a design sprint, a product team maps out dozens of new feature ideas, grouping them under themes like "user engagement," "accessibility improvements," and "cost-saving features."

  • Customer feedback analysis:  A support team reviews 200+ customer tickets and uses affinity mapping to identify recurring complaints around billing confusion, feature requests, and account setup issues.

  • Project management and workflow optimization: A project manager gathers team input on current pain points, then builds an affinity diagram to group issues by "communication gaps," "tool limitations," and "time management."

  • Competitor analysis and market research: A marketing team compiles competitor data from analyst reports and customer reviews, then uses affinity mapping to highlight themes like "pricing strategies," "feature gaps," and "messaging tone."

When is the best time to use affinity mapping?

Affinity mapping is most effective when you’re faced with information overload and need a clear way to organize your data. Consider using it when:

  • You have a large volume of qualitative data: If research findings, usability test results, and survey responses feel overwhelming, creating an affinity diagram can help you structure them into groups.

  • Patterns aren’t immediately clear: When raw data is scattered and unstructured, grouping related ideas can reveal hidden connections.

  • Your team needs alignment: If multiple stakeholders have differing perspectives, affinity mapping can create a shared understanding and highlight priorities.

  • You're defining next steps: Whether refining a product roadmap or solving a design challenge, categorizing ideas helps focus efforts.

By using affinity mapping at the right moments, you can avoid decision paralysis and turn complex information into clear insights.

How to create an affinity diagram

Creating an affinity diagram is a structured yet flexible process that you can use to organize large amounts of information into meaningful groups. Follow these steps to get started.

1. Define your focus

Start by identifying the problem or topic you want to explore. Whether analyzing data, brainstorming product ideas, or categorizing customer feedback, having a clear goal keeps your diagram useful.

Top tip: Frame your focus as a specific question – for example, "What are the biggest usability pain points in our product?"

2. Gather your data

Collect all relevant information – user research findings, survey responses, brainstorming ideas, or team feedback. You can write each idea on sticky notes or use a digital equivalent.

Top tip: “Perfect is the enemy of good” here, so free yourself: the more ideas, the better!

3. Find connections and group similar ideas

Look for patterns among your notes and cluster related ideas together. Grouping information reveals overarching themes and recurring issues.

Top tip: This builds on our tip above – don’t overthink categories at first. If an idea fits multiple groups, place it where it feels most relevant – refinements can come later.

4. Label each category

Give each cluster a clear, concise name that represents the ideas within it. These labels should capture key themes, such as “Navigation Issues” or “Feature Requests.”

5. Synthesize findings and draw insights

Step back and assess what the diagram reveals. What patterns stand out? Are there common pain points? Any gaps or unexpected insights?

Use color-coding or visual markers to highlight priority areas or recurring trends.

6. Decide on next steps

Depending on the context, your affinity diagram can guide decision-making, shape UX design improvements, or help prioritize action items.

Top tip: If you’re working with a team, use dot voting to quickly identify the most critical themes or issues to address first.

7. Refine and iterate

If new insights emerge or categories need adjusting, revisit and refine your diagram. The process is meant to be flexible and adaptive.

Top tip: Save and document your diagram – it can serve as a valuable reference for future discussions or design iterations.

Using affinity diagrams to make sense of UX research

UX research doesn’t end when you collect data – it’s what you do with that data that matters. But when you're dealing with interview transcripts, usability test results, and survey responses, it’s easy to get lost in a sea of conflicting feedback.

Affinity mapping brings order to this chaos. By grouping related data into clear themes, you can analyze patterns, synthesize findings, and derive insights that inform meaningful design decisions.

Here are five ways affinity diagrams can help you analyze and synthesize research:

  1. Organizing your research data: Affinity diagrams help you categorize interview transcripts, survey responses, pain points, and behavioral patterns into structured groups for analysis.

  2. Synthesizing findings: By clustering similar data points, you can identify patterns in user behavior, frustrations, and expectations that reveal deeper insights.

  3. Prioritizing user needs: The visual clustering reveals which issues appear most frequently, helping you focus on what matters most to users.

  4. Improving stakeholder communication: A well-structured affinity diagram visually conveys UX insights, making it easier to share findings and drive alignment across teams.

  5. Supporting UX design principles: By uncovering deep user needs, affinity diagrams help ensure data-driven design decisions that align with usability best practices rather than assumptions.

Example: Affinity mapping in action

Imagine you've conducted 10 user interviews for a mobile banking app. After transcribing the conversations, you’re left with pages (and pages) of unstructured feedback. Using an affinity map, you might group your findings into categories like:

  • Navigation issues: Users struggle to find key features like bill payments.

  • Trust & security concerns: Many express hesitation about linking external accounts.

  • Feature requests: Users frequently ask for a "dark mode" option.

With these themes clearly identified, you can prioritize fixes, make recommendations for design updates, and advocate for feature improvements backed by real user data.

Tips for creating successful affinity diagrams

Affinity mapping is a powerful tool, but its effectiveness depends on your approach. While processes vary between teams, these best practices will help you avoid common pitfalls and make your affinity diagrams as effective as possible.

Encourage open participation

Affinity mapping works best when everyone feels comfortable contributing. If team members seem hesitant to share, try setting a minimum quota for ideas during brainstorming. This encourages a range of perspectives and prevents the conversation from being dominated by a few voices.

Do: Involve cross-functional teams for well-rounded perspectives.

Don’t: Let a few voices dominate the conversation.

Let themes emerge naturally

One of the biggest mistakes is forcing categories too soon. Instead of imposing a structure from the start, let patterns emerge organically as you sort ideas. This helps to prevent bias and uncover unexpected connections.

Do: Group insights based on emerging patterns, not preconceptions.

Don’t: Overlook subtle connections that might yield valuable insights.

Keep it simple and flexible

Overcomplicating the process can make your affinity map harder to use. Avoid creating too many categories or getting stuck in analysis paralysis. If an idea fits in multiple groups, place it where it feels most relevant and adjust as needed.

Do: Create categories that are broad enough to be useful but specific enough to be meaningful.

Do: Use color coding or labels for visual clarity.

Don’t: Overload your map with excessive detail – clarity is more valuable than complexity.

Set a time limit to stay productive

Affinity mapping can take longer than expected, so set a time frame to keep things focused. If you’re running a session in person, you might allocate:

  • 15 minutes for brainstorming

  • 15 minutes for grouping

  • 15 minutes for discussion, with a buffer for refinements

Do: Use structured time blocks to maintain momentum.

Don’t: Let the process drag on indefinitely – know when to move forward.

Make your map actionable

An affinity diagram is most useful when it leads to clear next steps. Whether you're using it to analyze UX research findings, understand how to optimize a workflow, or for strategic planning, the final map should highlight key themes and priorities.

Do: Review and refine your map as new patterns emerge.

Don’t: Treat it as a static document – it should evolve as your understanding deepens.
