The document provides information on problem trees and objective trees. It defines a problem tree as a tool to represent a problem by showing the main problem, causes, and effects. An objective tree mirrors the problem tree but formulates the causes as means and effects as ends, transforming it into potential solutions. The document outlines how to create both, including identifying the core problem, direct effects and root causes for a problem tree, and reformulating these into positive objectives linked by means-end relationships for an objective tree. Examples of partially completed trees are included for a bus accident and river water quality.
