Tree Testing

Turns observations, needs, and patterns into a tangible result by drafting the tree, writing tasks, and iterating labels and structure.

Core question
Can participants find the correct answers in the proposed navigation structure, and which paths lead them astray?

Purpose

The method helps clarify observations, needs, and patterns concretely. It groups observations into patterns, questions, and decisions. The result is captured as findability metrics, path analysis, and a revised information architecture.

How it works

The team follows the steps: draft the tree, write test tasks, run participant tests, check success rates, and iterate labels and structure. Each step is captured visibly. At the end, findability metrics, path analysis, and a revised information architecture are available so decisions, tests, or actions can follow directly.

Deep dive

In detail

Tree Testing follows a clear working logic: drafting the tree, writing tasks, running participant tests, checking success rates, and iterating labels and structure. This turns the method into a visible thinking process rather than only a conversation. Participants move step by step from raw material, observations, or options toward a shared structure. As a result, findability metrics, path analysis, and a revised information architecture support decisions, learning, or further planning.

Facilitation

Prepare a clear guiding question, the right information, and a visible workspace. Plan about 1-2 days with 10-30 participants and use the format asynchronously. The facilitation needs notable structure and preparation; short timeboxes, visible intermediate results, and a parking lot for open questions help.
