This document discusses causal systems analysis and fishbone diagrams as tools for identifying the root causes of problems. It provides an overview of the causal systems analysis process, which involves defining the problem, identifying main categories of potential causes, and then asking "why" multiple times to drill down to underlying causes within the system that can be influenced. The document includes examples of a fishbone diagram that maps relationships between different root causes and a high teacher turnover rate problem. It also provides tips for creating a fishbone diagram, such as staying user-centered by considering different perspectives, and using data when possible to test hypothesized causes.
