As most marketing and project management leaders know from experience, gathering customer data and research is the first step toward better understanding behaviors and needs. Yet sifting through all of the information that comes in from various sources can be overwhelming, time-consuming, and unproductive when tackled disparately.
Fortunately, there are solutions available to help leaders make sense of customer and user experience data. One such method, the affinity diagram, helps users organize unwieldy research and develop clearer ideas for improving customer experiences as a result of better structured data.
In this article, we’re taking a closer look at affinity diagrams and how to use them to better approach research for more tangible results. To do this, we’ll cover:

- When to use an affinity diagram
- How to create an affinity diagram

What is an affinity diagram?
An affinity diagram, also called an affinity map, is a method of organizing output from various sources by grouping them based on similar characteristics or relationships. Affinity diagrams serve to help leaders make sense of large amounts of data or feedback to better understand their importance within the larger context of a project or initiative.
Affinity diagrams got their start in the 1960s as a project management tool created by Kawakita Jiro. Originally used to sort through the ideas set forth during brainstorming sessions, these diagrams evolved to group like items together and help teams simplify issues, identify patterns, and solve problems without being overwhelmed by the information.
Affinity diagrams are helpful when faced with disordered or vast amounts of data points that are difficult to organize and develop conclusions from. They can also be extremely useful in group situations where there are a number of contributors or data sources (or both) coming together with little to no organization to them. Affinity diagrams can easily be created using on-hand office supplies, including whiteboards or Post-it Notes, to allow items to be jotted down and moved between categories as they are discussed.
A great way to picture an affinity diagram is an assortment of Post-it Notes, each with a different term or item listed, placed on a board and grouped together based on their similarities.
When to use an affinity diagram
Affinity diagrams are most helpful when dealing with a large number of ideas or issues that need to be organized to address them efficiently and productively. These maps are broken down into single items, tasks, ideas, or data points that can be rearranged under common headings or categories to make better sense of the patterns and approach needed.
This organizational method can also help with brainstorming sessions where ideas need to be seen clearly and structured based on a group consensus.
Here are some of the most common use cases for affinity diagrams:
- Organizing brainstorming sessions
- Sorting survey results
- Understanding customer data
- Gaining group consensus on a project
- Demystifying large or complex ideas
- Consolidating chaotic facts or feedback
- Creating product or project roadmaps
How to create an affinity diagram
While managers and leaders can create an affinity diagram on their own, some of the best results are achieved when working in pairs or groups.
When preparing to make an affinity map, make sure you have collected all the data points or information in advance for organization and processing during the creation phase. If pulling together a team to work on the effort, the group will want to designate a leader or point person to help document feedback and organize. And of course, managers or leaders should encourage everyone involved to contribute their ideas as the diagram develops.
Follow these steps to build an affinity diagram:
Step 1 — Create Post-it Notes for your ideas
Start by documenting every idea or data point that needs to be accounted for in your project. Each individual item should be written out on a Post-it Note or a note card so that it can be moved around as needed during later steps. Keep the ideas short and to the point so everyone knows what’s being listed. If working with a larger team, write large or with a marker to make sure everyone can see the items as they’re being written out.
The goal is to create a record of every contribution to the project. If brainstorming, these can be created in real time, noting each suggestion as it’s put forth and worrying about its place in the grand scheme of the project later. When dealing with data or survey feedback, each Post-it Note can reflect a single contribution and include the number of times it was put forth to avoid duplication.
Step 2 — Put the Post-it Notes into groups
Next, look for the affinities, or similarities, between the items that have been noted. Natural categories or groups should start to show themselves as the team reviews all the input. Look for patterns and organize the Post-it Notes into groups, sticking them together under headings on a board, wall, or large table everyone can see. Consider creating header Post-it Notes or cards that can be rearranged as the process progresses.
Feel free to shift the categories as you move forward. This is a fluid process, and new comparisons and connections might start to show as the team discusses the items at hand.
