How to Use Affinity Diagrams to Organize Your Ideas Better
What Is an Affinity Diagram?
An affinity diagram is a popular visualization tool that organizes related ideas, data, or concepts. It also facilitates organized design thinking, visualizes connections, discovers patterns, and derives solutions.
Need a quick example to help you relate? Here’s a scenario showing how affinity diagrams can be game changers.
🔹Scenario
Your team is brainstorming ways to improve customer service. After gathering ideas, you’re left with a long, scattered list.
Let’s assume that team members have listed down:
- Reducing response times
- Personalizing communication
- Offering self-service options
- Implementing a chatbot
- Training staff on new systems
🔹What affinity diagrams do
All these ideas are categorized with the help of an affinity diagram tool. Considering the scenario, here are a few possible categories:
| Category | Ideas |
|---|---|
| Response efficiency | “Reducing response times” and “Implementing a chatbot” |
| Customer interaction | “Personalizing communication” and “Offering self-service options” |
| Team development | “Training staff on new systems” |
🔹The effect of the diagram
- Connections are clear
- Actions and decisions are prioritized and structured
- Team efforts are focused
Key components of an affinity diagram
With a clear picture of how affinity diagrams can sharpen focus and prioritize actions, let’s dive into the key components that make them effective.
- Header: This is the central focus or topic of the diagram, displayed at the top for clarity. It’s often aligned with business targets or specific goals
- Ideas and data points: These are the individual thoughts or data your team has gathered. They’re typically collected in a separate brainstorming or ideation session
- Category cards: This element is how you organize ideas into meaningful clusters
💡 Pro Tip: You can group ideas under each main category based on logical systems or specific relationships.
Affinity diagram vs fishbone diagram
Before diving into the “how-to,” let’s clear up a common misconception. Project teams sometimes confuse an affinity map with a fishbone diagram.
While the mix-up is understandable, it’s important to remember that these tools are quite different. Knowing these differences is crucial for using them effectively.
Here’s a quick table to highlight the key nuances:
| Aspect | Affinity diagram | Fishbone diagram |
|---|---|---|
| Purpose | Organizes and groups related ideas to identify patterns and insights | Identifies the root causes of a specific problem or issue |
| Structure | Clusters ideas into natural categories or themes | Visually represents causes and sub-causes leading to a problem |
| Usage | Used during brainstorming or when dealing with scattered information | Used for problem-solving by analyzing cause-and-effect relationships |
| Focus | Focuses on organizing data and revealing connections | Focuses on understanding why a problem is occurring |
| Output | Grouped ideas with common themes for better decision-making | A diagram showing the hierarchy of causes contributing to a problem |
| Visual appearance | Non-linear clusters of ideas or sticky notes | A fishbone-like structure with branches representing causes |
When and How to Use Affinity Diagrams
Affinity diagrams are powerful only when used at the right time. Ill-timed affinity mapping may result in wasted resources, misaligned strategies, or missed opportunities.
When should you use affinity mapping?
To stay on the right track, here’s when to use the affinity diagram:
- Grouping ideas after brainstorming: Opt for this tool after you’ve generated a pool of ideas. Affinity diagrams facilitate logical grouping and pattern identification, not data creation
- Simplifying complex problems: Create an affinity diagram to break complex problems into small chunks. Simplify the multiple variables and factors by visualizing them into manageable sections
- Processing large datasets: Simplify analysis of large data sets with affinity diagrams. Use this tool when handling qualitative data, such as customer feedback, survey results, or research findings
- Driving process improvement: Opt for an affinity diagram when explaining and identifying improvement. Map out the steps and use the affinity diagram to spot bottlenecks or inefficiencies
- Creating information structure: Adopt affinity diagrams when data points are unorganized. Give information like notes, ideas, or observations a clear structure and highlight key common themes
📝Note: Affinity diagrams begin after brainstorming and data collection, focusing on organizing the collected information rather than creating new ideas.
Steps to create affinity diagrams
Here are the five clear steps and the best tools involved in the affinity diagram process:
Step 1: Define your challenge
The first part of an affinity diagram is to establish why you must create one. This involves clearly articulating the problem or question you aim to address.
Recording this helps you maintain focus and keeps everyone on the same page. This demands efficient and versatile documentation, and shines with a dedicated tool designed for that.
Docs is an excellent documentation tool for mapping thoughts and processes. Its rich markdown formatting helps structure pain points. Segmenting content based on departments or functions with built-in subpages is easy.
The tool features real-time collaboration, instant commenting, and editing. It is integrated with an AI tool Brain for clear, concise, and error-free writing.
Using Docs to define the problem is pretty simple. Here are the four steps:
Action I: Go to Docs in your workspace
Action II: Create a new Doc. Then, name your document. For example, ‘Affinity Diagram: Customer Service.’
Action III: Pen down the details. Map the date, focus, goals, and objectives. Then, jot down your pain points. This will help provide context for the affinity diagram, its purpose, and desired outcomes.
Action IV: Share the Doc. Once your content is structured and mapped, allow your team members to add their pain points and challenges.
💡 Pro Tip: Add standard questions to your Doc to help your team identify pain points. This will make it easier for everyone to contribute and organize their thoughts. For example, if the focus is customer service, questions could be:
- “What are the most common customer complaints?”
- “Where do customers experience the longest wait times?”
- “What are the biggest obstacles to customer satisfaction?”
Step 2: Add in your ideas or data points
With the reason established, you have the agenda for your affinity diagram. The next step is to import or record your ideas or data points. New ideas and data points come from brainstorming and are best visualized or mapped on a blank canvas.

Best Practices that Facilitate Effective Affinity Diagrams
Aside from the steps we’ve covered, here are a few best practices for an effective affinity diagram:
- Enable a silent brainstorming exercise: Ask participants to map their ideas on individual sticky notes or cards in silence. This helps generate a broader range of ideas without groupthink or bias
- Group ideas: Have participants collaboratively sort ideas into groups based on similarity, but do this without talking at first. This step allows for organic, unbiased clustering of thoughts
- Encourage discussions: Invite participants to discuss and refine the groupings after the initial sorting. These conversations clarify ambiguous ideas, align categories, and facilitate affinity mapping
- Limit categories: Avoid overcomplicating the diagram with too many groups. Stick to meaningful clusters that simplify the problem, usually around 5–10 categories
- Have a dedicated facilitator: To keep the session on track, assign a facilitator for each brainstorming session and an affinity diagram for prompt clarifications. Facilitators should also encourage quieter participants to share their view
- Use visual markers: Once grouped, use colored markers or symbols to emphasize critical categories. This will help identify patterns that the team may want to focus on during follow-up
- Summarize and move to the next steps: Summarize the insights gained immediately after the diagram is complete. Also, discuss the next steps in the same meeting. This leads the group to decide on concrete actions
⚡ Bonus Tip: Use Brain as your AI Project Manager. Once your affinity diagram is ready, Brain will generate insights and summaries for you to act on.
