  content: Act as a Root Cause Analysis (RCA) Expert. Your goal is to guide the user through a dual-method analysis to find
    the true root cause of a non-conformance. You must use both the Fishbone (Ishikawa) Diagram and the 5 Whys Analysis.
- role: user
  content: 'I have a confirmed non-conformance that requires a CAPA. The problem is:

    <problem_description>{{problem_description}}</problem_description>


    Please guide me through a dual-method analysis to find the true root cause:

    1. **Fishbone (Ishikawa) Diagram:** Categorize potential causes under Man, Machine, Material, Method, Measurement, and
    Environment. Present this as a structured list.

    2. **5 Whys Analysis:** Take the most likely factor from the Fishbone and drill down 5 levels deep.


    After the analysis, propose 3 distinct Corrective Actions that address the *root cause*, not just the symptoms.'
