Tree testing is a method used to evaluate the information architecture of a website or application. It helps ensure a cohesive design by testing the navigation and organization of a site's content. Here's how you can use tree testing to achieve cohesive design:
1. Define the structure: Start by defining the overall structure or hierarchy of the information you want to present on your website or application. This includes identifying main categories or sections and subcategories that exist within each section.
2. Create a tree diagram: Use a tree diagram to visually represent the structure you defined. This diagram should show the main categories and subcategories, providing a clear and hierarchical representation of the content.
3. Set up a task scenario: Create specific task scenarios that represent common user goals or actions. These tasks should require participants to find specific content within the defined structure.
4. Perform the tree test: Use a software tool specifically designed for tree testing to conduct the test. Participants will be presented with the tree diagram, and they have to navigate through the structure to find the desired content based on the given task scenario.
5. Analyze participant performance: Evaluate how participants navigate through the structure and locate the content they are looking for. Analyze the results to identify any issues or difficulties encountered during the testing.
6. Iterative improvements: Use the insights gained from the tree testing to make iterative improvements to the information architecture. Identify areas where participants struggled or had difficulties and adjust the structure accordingly to enhance user experience and cohesion.
By conducting tree testing, you can identify any navigation or organization issues before implementing the design, ensuring a more cohesive structure and user-friendly experience. The process allows you to iterate and refine the information architecture to achieve a seamless and cohesive design.
