To create a Tree Diagram

  1. Develop a clear statement of the problem, issue, or objective to be addressed. Place it on the left side of a board, wall, or easel and work toward the right.
  2. Brainstorm all of the sub-goals, tasks, or criteria necessary to accomplish or resolve the issue.
  3. Repeat this process using each of the sub-goals until only actionable tasks or elements remain.
  4. Check the logic of the diagram in the same way as the Ishikawa: Start at the right and work your way back to the left by asking: If we do this, will it lead to the accomplishment of the previous task?
