This document discusses cause-effect diagrams, also known as Ishikawa or fishbone diagrams. These diagrams identify the potential causes for a specific effect or problem. The document provides an example fishbone diagram analyzing the causes of students arriving late to class. The three root causes identified are: students not taking responsibility, students experiencing psychological or emotional problems, and a lack of consequences for lateness. The document then provides solutions to address each of these root causes, such as clearly communicating attendance policies and using campus resources to help students with psychological issues.
