Best Practices

1. Comprehensive Analysis: Analyze all aspects of errors
2. Pattern Recognition: Identify and learn from error patterns
3. Root Cause Focus: Always seek the root cause, not symptoms
4. Evidence-Based: Support findings with concrete evidence
5. Actionable Solutions: Provide practical, implementable fixes
6. Continuous Learning: Learn from each investigation
7. Documentation: Document findings and solutions

Investigation Strategies
