Tree Diagram
The Tree Diagram is used to figure out all the various
tasks that must be carried out to achieve an objective.
It is a useful planning tool that helps structure the
activities of the team. If the group uses it carefully and
thoroughly, it will give them a better understanding of
the a project, and will help the team focus on specific
tasks that are needed to get something done.
The Tree diagram is a linear thinking tool. Each level of detail is determined by
moving from left to right, and asking, "What needs to happen to achieve this
outcome, goal or action?" Participants usually start off slow and then pick up
momentum as they become familiar with linear thinking.
Tree Diagram Instructions
- The Tree Diagram maps out details of a plan and levels of tasks needed to
accomplish a goal.
- The major headings are the tasks, the sub-goals or the means by which the
plan will be achieved.
- Breakdown each major task area into more detail by providing answers to the
question "What needs to addressed to achieve the solution?" Repeat the
question for each successive level until the team agrees there is enough
detail to complete the plan or until all the tasks are assigned.
- Review the completed Tree Diagram to determine if all the tasks need to be
done. If team members are unsure about the value of some tasks/activities,
use decision-making tools to evaluate the possible activities against things
such as costs, risks, timelines, and feasibility.
- Review the completed Tree Diagram to determine if all the necessary tasks
are included. If necessary tasks were omitted, add them to the diagram.
