You’re organizing a community art fair and have asked local artists to submit their ideas. Soon, the sticky notes start piling up with suggestions—abstract paintings, ceramic sculptures, live art demos, craft workshops, and more.
The sheer number of ideas is exciting but overwhelming, making it hard to see how everything fits together.
Wouldn’t it be simpler to group these ideas into categories, such as ‘exhibits,’ ‘workshops’, and ‘performances’?
That’s exactly what an affinity diagram does. It helps you organize related ideas into a structured plan—just like sorting your art fair ideas into clear categories to create a cohesive event plan.
In this article, we’ll explore how you can use affinity diagrams to guide decision-making and problem-solving in the workplace. But before that, let’s get our basics clear.
Meta Title: How to Create an Affinity Diagram
Summarize this article for me pleaseWhat Is an Affinity Diagram?
An affinity diagram is a visual tool for organizing tasks, ideas, or research findings into meaningful clusters. It’s especially useful during brainstorming sessions or project planning, as it helps make sense of complex information by highlighting patterns and themes that might not be obvious at first glance.
Whether you’re a designer, project manager, researcher, or business decision-maker, affinity diagrams would be a time-saving addition to your workflow.
Origin and development of affinity diagram
While the idea of data grouping isn’t new, there was no standardized terminology or method for it a few decades ago.
The term ‘affinity diagram’ (also known as the KJ Method) was first introduced by Jiro Kawakita, a Japanese anthropologist, in the 1960s. He developed this method to synthesize the vast ethnographic data collected during his explorations in the Himalayas.
Affinity mapping eventually made its way into the corporate world, helping organizations collect and analyze information systematically and approach problem-solving collaboratively. It quickly gained traction, particularly in the fields of UX design and project planning.
Over time, it has become a staple in various management practices, including Total Quality Management (TQM) and Six Sigma.
What is affinity mapping?
Affinity mapping is the process of creating an affinity diagram. It involves jotting down individual ideas or pieces of information on separate notes or cards and then sorting these into groups based on their similarities.
By doing this, you can visually organize information and spot relationships between different pieces of data. It’s a great way to make a big, unwieldy set of information more manageable and insightful.

Affinity diagram vs. mind mapping
Both affinity diagrams and mind maps are tools for organizing information, but they work in slightly different ways. Basically, an affinity diagram groups similar items based on their natural relationships.
On the other hand, mind mapping starts with a central idea and branches out with related thoughts. It’s best suited for brainstorming and exploring different facets of a single topic.
Let’s understand the differences between affinity diagrams and mind maps with an example:
Affinity diagram: Suppose your content marketing team is brainstorming topics for a new blog series on ‘Effective Social Media Strategies.’ You gather various ideas, such as:
- Case studies of successful campaigns
- Tips for using analytics
- Social media tools reviews
- Strategies for increasing engagement
You write these ideas on sticky notes and then group them based on similarities.
In this process, you find that ‘Case studies of successful campaigns’ and ‘Strategies for increasing engagement’ fit into the ‘Success Stories’ category, while ‘Tips for using analytics’ and ‘Social media tools reviews’ fall under the ‘Practical Tips’ category.
And that’s it—you have the main themes for your blog series.
Mind map: Now, let’s say you’re creating a content strategy for the same blog series. So you start with ‘Social Media Strategies’ in the center of your mind map. From there, you create branches for key elements like ‘Content Types, ‘Distribution Channels,’ ‘Target Audience,’ and ‘Success Metrics’.
Under ‘Content Types,’ you branch out into ‘How-to Guides,’ ‘Infographics,’ and ‘Video Tutorials.’
Under ‘Distribution Channels,’ you can have branches for ‘Meta,’ ‘LinkedIn,’ and ‘Instagram.’
And there you go—you have a visual map to see the topics and subtopics of the primary idea.
Summarize this article for me pleaseStep-by-Step Guide to Creating an Affinity Diagram
We’ll walk you through the process of creating an affinity diagram. Follow these six steps, and you’re ready to cut through complex data sets and get to the key information.
1. Define the problem
Sometimes, approaching a problem from a fresh perspective can lead to breakthroughs. Therefore, ask yourself if re-organizing the information differently might make the issue more understandable and manageable.
If the answer is yes, here’s the first step to creating an affinity diagram—clearly define the problem/topic you want to address and the goals you want to achieve by creating the diagram.
So, take some time to reflect on the issue at hand and determine exactly what you’re trying to solve or understand. Do you need to make an important decision? Or is there a project that’s not progressing as expected? Being specific about the problem helps you gather relevant information.
Affinity diagrams work well when your goals/expectations revolve around:
- Analyzing customer research data
- Generating ideas for new projects
- Identifying issues within your existing processes
For this step, you can use ClickUp Docs. You can work in real time with your remote team to list the key problems you’re facing and the objectives you want to achieve by creating an affinity diagram. Since it lets multiple people edit simultaneously, everybody can get their thoughts down in the shortest time.
2. Gather information
Once you clearly understand the problem, it’s time to gather information. This is where brainstorming comes into play.
Involve cross-functional teams and external stakeholders in the process. They’ll bring in different opinions and you’ll get a wide range of inputs.
Don’t hold back—note down every idea, no matter how small or unconventional.
This step works great if everyone writes their ideas on good old sticky notes. However, when the inputs are numerous, you might want to take the digital route to effectively capture and analyze the data.
ClickUp Whiteboards, a platform for real-time visual collaboration, would be a great fit for your brainstorming session. The tool offers a creative canvas where your team members can write notes, add shapes, draw freehand, and put their best ideas on the table.
You can also link relevant tasks, files, and documents from your ClickUp Workspace to make the notes more contextual.

3. Sort and group information
With all your ideas laid out, the next step is to sort and group them into categories. Start by reviewing the collected items and identifying common themes or patterns.
For example, if you’re working on improving customer service, you might create categories like ‘Customer Feedback,’ ‘Staff Training’, and ‘Process Improvements.’ Label each category clearly and also organize the items within each group in logical order.
With this arrangement, you can visualize relationships between different pieces of information and see the bigger picture.
You can use ClickUp Mind Maps (within ClickUp Whiteboards) to illustrate the relationship between ideas. The tool enables you to:
- Break down complex ideas into small units for clarity
- Edit, delete, or reorganize ideas to fit your requirements
- Add ideas to the map and convert them into actionable tasks
- Reorganize the map with Re-Layout and preserve the hierarchy
For instance, under ‘Staff Training,’ you can have subcategories like ‘Soft Skills Training,’ ‘Chat Support Training,’ and ‘Technical Training’. The mind map provides a comprehensive picture of the different facets of a single task/idea.
4. Create the affinity diagram
Now, it’s time to arrange your grouped information into an affinity diagram. Place your categories and items on a whiteboard and arrange them in a way that visually represents their relationships.
Additionally, use lines, arrows, or other visual connectors to show how different categories and ideas are connected.
Don’t be afraid to rearrange things as you go along; the goal is to create a diagram that effectively communicates the connections and patterns within your data.
If you’re using ClickUp Whiteboards, you can drag and drop your ideas, rearrange them, and add visual cues (arrows, connectors, color-coding, etc.) for seamless categorization.
5. Review and refine your affinity diagram
Once your diagram is in place, take a step back and analyze the layout. Ensure that the diagram includes all the groups and items and the connections accurately reflect the relationships between different pieces of information.
Seek feedback from team members or key stakeholders to get their perspectives and identify any gaps or areas for improvement. Based on the feedback, make necessary adjustments, if any.
Be prepared—during this step, you might have to reorganize categories, add/omit information, or clarify connections.
ClickUp Whiteboards makes this step a breeze. Your internal team and stakeholders can collaborate directly on the whiteboard and make changes to the affinity diagram as required. No need for to-and-fro email communication or calls—get the work done in a single platform.
6. Prioritize and act
Finally, use your affinity diagram to prioritize categories and develop a plan of action. Look for key themes or clusters that highlight the most critical areas needing attention.
For example, if the diagram reveals that the majority of issues belong to the ‘Customer Feedback’ category, you might take them up first.
Outline a plan to address each priority area, assign responsibilities, and set clear timelines. As you implement these plans, track progress and make adjustments to your plan on the go based on outcomes and feedback.
On ClickUp Whiteboards, it’s easy to move from understanding the problem to taking effective action. When you identify an idea/issue that needs immediate action, you can create a ClickUp Task directly from your whiteboard.
Thanks to 15+ customizable ClickUp Views, you can track progress the way you want—whether you’re looking for a bird’s-eye view of the entire workflow or a granular view of a specific task. Here are some views you might find useful:
- Gantt View: It offers a visual timeline of tasks, showing how they overlap and interact with one another. You can see the project schedule and dependencies at a glance with this view

Let’s explore how you can implement affinity diagramming in different aspects of project management:
Affinity diagrams in design thinking
Design thinking is a problem-solving approach that focuses on developing innovative solutions tailored to users’ needs. It involves five non-linear stages—Empathize, Define, Ideate, Prototype, and Test. Affinity diagrams are useful in many of these stages.
- In the Empathize stage, where the goal is to deeply understand users through methods like interviews and observations, an affinity diagram helps you categorize large volumes of qualitative data
- In the Define stage, the clusters from your affinity diagram allow you to focus on the recurring problems users have been facing
Affinity diagrams and Six Sigma
Six Sigma methodology aims to improve business processes and reduce defects to achieve near-perfect quality and performance. It follows the DMAIC framework (Define, Measure, Analyze, Improve, Control), and affinity diagrams enable you to navigate each of these steps with an organized approach.
Here’s how:
| DMAIC phase | Use of affinity diagrams |
| Define | Organize customer needs and project goals into clear categories, ensuring everyone is on the same page |
| Measure | Sort and visualize data metrics and identify trends and key areas for evaluation |
| Analyze | Cluster data to locate root causes and patterns |
| Improve | Group and evaluate potential solutions during brainstorming sessions |
| Control | Categorize and monitor KPIs and project risks |
Affinity diagrams in decision-making
It’s overwhelming to analyze a large set of data points, ideas, or feedback and make concrete decisions based on this analysis. An affinity diagram can be a powerful tool for sorting everything into clear, organized categories.
For instance, if your team is brainstorming new features for a product, you might receive tens of suggestions. Using an affinity diagram, you can group similar ideas together and quickly spot common themes/priorities.
They also show how different input pieces fit together, making it easier for your team members to reach a consensus and make well-informed decisions.

Affinity diagrams in UX
In UX design, affinity diagrams empower you to make sense of the qualitative data you gather from customer research, like interviews or surveys.
For example, let’s say some customers talk about difficulties in navigating the website while others mention a lack of customization options.
An affinity diagram lets you group these notes into clusters based on their common themes, such as ‘navigation issues’ or ‘feature requests,’ and you can start noticing patterns in users’ needs and their pain points.
Affinity diagrams in Agile
Agile teams juggle multiple tasks and ideas simultaneously, and affinity diagrams are perfect to keep things well-structured. Here’s how:
- During backlog refinement, you might have multiple user stories or tasks that need sorting. Using an affinity diagram, you can group related stories and prioritize them more effectively
- During sprint planning, these diagrams help you visualize and organize tasks and make the planning process smoother
- In Agile retrospectives, affinity diagrams serve as a great tool to group feedback and identify recurring issues so teams can locate areas for improvement and craft actionable plans
