What is an Affinity Diagram?

Brainstorming is a great way to come up with creative ideas as a team. But it isn’t the most structured way to work with this board full of ideas and information, and at the end of the session teams may leave teams feeling frustrated if there are no clear takeaways. This is where an Affinity Diagram comes in (also known as an affinity chart or K-J method after its founder Kawakita Jiro).

It is a visual map that organizes ideas into categorized clusters after the initial brainstorming. This process of creating affinity diagrams is known as affinity mapping. Affinity mapping allows all ideas to be strategically analyzed- instead of just focusing on one of two standouts. As clear themes start to emerge, you can consider multiple solutions to each problem.

We’ve created a simple affinity diagram template and guide you can use for your Affinity Diagrams. Read on to see how it works.

We’ve broken the mapping process down into three main parts.

Step 1: Ideation

It’s a great idea generation technique that prioritizes participation and inclusivity. It’s also great for generating a large number of ideas in a short period of time. Try the brainwriting technique with our free template.

Six thinking hats

This method focus on outside-the-box thinking for innovative problem solving. Six thinking hats is effectively used both in brainstorming as well as strategic decision making.

How Might We

How might we is an exercise used primarily in design thinking to reframe the problem as a challenge and focus on finding innovative solutions from different perspectives. Your How Might We could ideally become a launchpad for your brainstorming session.

Step 2: Diagraming

Next, it’s time to start looking at the ideas to find affinities and connections. It can help to talk through why you think ideas belong together and encourage discussion within the group. Be prepared for this step to take the longest, but eventually you will be able see a clear map emerge.

Once categories or themes have emerged, you can label the category areas and begin placing the sticky notes in the relevant categories.

The final step in the Affinity diagram is to select the final one or two ideas from each category and drag them into the lower Refinement area. Now, you should have identified exact solutions to your initial problems.

Step 3. Wrap-up

Once you have organized each group, think about the next steps and create a plan of action by assigning tasks to team members.

If you want to take it a step further, try adding the Action Priority or Priority Matrix templates to the board.
