Steps in developing a Problem Tree Analysis:
1. Identify major existing problems based on available information
2. Select an individual starter, a focal problem for analysis
3. Look for related problems to the starter problem and identify substantial causes/effects
4. Construct the problem tree by establishing a hierarchy of cause and effect relationships
5. Connect the problems with cause-and-effect arrows
6. Review the diagram, verify its validity and completeness, and make necessary adjustments
