Understanding the relationships between different elements is key to product development. This is where affinity charting comes in. Also known as KJ analysis, affinity charting is a tool that helps developers to see the connections between ideas. It can be used to brainstorm new product features, redesign existing products, or understand customer needs
Affinity charting is based on the principle that people are more likely to come up with creative ideas when they are not restricted by linear thinking. To create an affinity chart, developers write down all of the ideas related to a project on individual Post-It notes. These notes are then grouped together based on similarity. This process helps developers to see relationships between different ideas that they may not have been aware of before
Affinity charting is an important tool for physical product development because it allows developers to quickly identify potential problems and come up with creative solutions. For example, if a team is designing a new car, they may use affinity charting to brainstorm all of the possible features that could be included in the design. By seeing all of the ideas in one place, they can quickly identify any areas where there may be gaps in the design or potential problems that need to be addressed.
