The document describes the tree diagram as a systematic tool for mapping all activities necessary to achieve a goal and identifying factors contributing to a problem. It emphasizes the strength of this method in examining the logical and chronological links between tasks. An example of applying a tree diagram for safety performance is provided, including various strategies such as training, inspections, and benchmarking.

1. Tree diagram
The systems flow / tree diagram is used to systematically map
out the full range of activities that must be accomplished in
order to reach a desired goal. It can be also used to identify all
the factors contributing to a problem under consideration. One
of the strengths of this method is that it forces the user to
examine the logical and chronological link between all the tasks.
The example of the tree diagram for Safety performance is
shown on the next slide.
