A flow chart is made linking everything in the system to the “Primary Useful Function” and the “Primary Harmful Function”.

Secondary functions are included, going to the level of detail required by the particular need that created the project.

The links between nodes in the flow chart represent causal relationships.

The output is a comprehensive set of problem statements defining the problem space.
